Description

Connector with a plurality of connectors

Technical Field

The present disclosure relates to connectors.

Background

The connector disclosed in patent document 1 includes a housing capable of accommodating a terminal component, and a stopper body mounted to the housing so as to be movable between a temporary locking position and a normal locking position. The housing has a cover. The cover has a contact surface at an inner bottom portion thereof fitted with the counterpart connector. The stopper has a projection projecting forward from the abutment surface. The stopper is configured to lock the terminal in the normal locking position to restrict backward detachment of the terminal. When the stopper is located at the temporary locking position, the protruding piece interferes with the counterpart connector to restrict the fitting of the counterpart connector. This makes it possible to detect (recognize) forgetting of the movement operation of the stopper body to the main locking position. Patent document 2 also discloses a connector capable of detecting the position of a stopper. Patent document 3 discloses a connector capable of detecting poor mounting of terminal parts.

Disclosure of Invention

Problems to be solved by the invention

Unlike patent document 1, the following conventional techniques are also known: when the stopper is in the temporary locking position, a part of the stopper protrudes from the outer surface of the housing to interfere with the counterpart connector, thereby detecting that the stopper has not moved to the main locking position. However, in the prior art or the technology of patent document 1, a detection mechanism for detecting the position of the stopper is provided at an end portion of the housing or outside the housing, which is separated from the housing portion of the terminal component. Therefore, there is a problem in that the connector is enlarged.

Accordingly, an object of the present disclosure is to improve a technique of detecting a position of a stopper while avoiding enlargement of a connector.

Means for solving the problems

The connector of the present disclosure includes: a1 st connector housing of a1 st connector and a 2 nd connector housing of a 2 nd connector which can be mutually jogged; a1 st terminal part accommodated in a1 st cavity formed in the 1 st connector housing; and a stopper body that is movable from a temporary locking position to a normal locking position with respect to the 1 st connector housing in a direction intersecting a fitting direction of the 1 st connector housing and the 2 nd connector housing, wherein the 1 st terminal component is locked in the normal locking position, the 1 st connector housing has a recess opening at a fitting surface facing the 2 nd connector housing between the 1 st cavities, the stopper body has a stopper body side interference portion facing an inner side of the recess, and the 2 nd connector housing has a housing side interference portion arranged at a prescribed depth inside the recess when the stopper body is positioned in the normal locking position, and arranged at a shallower interference than the prescribed depth inside the recess when the stopper body is positioned in a halfway position from the temporary locking position toward the normal locking position or the temporary locking position.

Effects of the invention

According to the present disclosure, a technique of detecting a position of a stopper while avoiding enlargement of a connector can be improved.

Detailed Description

[ Description of embodiments of the present disclosure ]

First, embodiments of the present disclosure will be described.

The connector of the present disclosure is provided with a connector,

(1) The device is provided with: a 1 st connector housing of a 1 st connector and a2 nd connector housing of a2 nd connector which can be mutually jogged; a 1 st terminal part accommodated in a 1 st cavity formed in the 1 st connector housing; and a stopper body that moves from a temporary locking position to a normal locking position with respect to the 1 st connector housing in a direction intersecting a fitting direction of the 1 st connector housing and the 2 nd connector housing, wherein the 1 st terminal component is locked in the normal locking position, the 1 st connector housing is restricted from being separated from the 1 st cavity, the 1 st connector housing has a recess opening at a fitting surface facing the 2 nd connector housing between the 1 st cavities, the stopper body has a stopper body side interference portion facing an inner side of the recess, and the 2 nd connector housing has a housing side interference portion arranged at a prescribed depth inside the recess when the stopper body is positioned in the normal locking position, and arranged at a shallower interference with the stopper body side interference portion than the prescribed depth inside the recess when the stopper body is positioned in a halfway position from the temporary locking position toward the normal locking position or the temporary locking position.

When the stopper is positioned at the main locking position, the housing-side interference portion of the 2 nd connector housing is disposed inside the recess portion at a predetermined depth, and the 1 st connector housing and the 2 nd connector housing can be brought into a fitted state.

When the stopper is located at the temporary locking position or the intermediate position, the housing-side interference portion of the 2 nd connector housing interferes with the stopper-side interference portion and is disposed shallower inside the recess, and fitting of the 1 st connector housing and the 2 nd connector housing is restricted, so that the 1 st connector housing and the 2 nd connector housing cannot reach the fitted state. This makes it possible to detect (recognize) that the stopper has not moved to the normal locking position.

In particular, according to the above configuration, since the stopper-side interference portion faces the inside of the recess portion formed between the 1 st cavities in the 1 st connector housing, the 1 st connector housing is not enlarged by providing the stopper-side interference portion, and enlargement of the connector can be avoided.

(2) Preferably, the 2 nd connector housing has a cylindrical cover portion, the 2 nd terminal element connectable to the 1 st terminal element protrudes to the inside of the cover portion, and the housing-side interference portion is formed in an anti-tightening portion protruding side by side with the 2 nd terminal element inside the cover portion.

According to the above configuration, the tightening prevention portion can have both the function of preventing the tightening engagement of the 1 st connector housing and the 2 nd connector housing to protect the 2 nd terminal component and the function of detecting the position of the stopper. Therefore, the structure of the 2 nd connector housing can be simplified and the enlargement of the connector can be more avoided than when the two functions are formed in separate portions of the 2 nd connector housing.

(3) Preferably, the stopper body has a stopper body and a regulating portion protruding from the stopper body to one side in the fitting direction, the stopper body side interference portion is formed in the stopper body continuously with the regulating portion, the 1 st connector housing has a stopper body receiving hole that receives the stopper body, and the stopper body receiving hole is opened in an opening shape corresponding to a cross-sectional shape of the stopper body and the regulating portion on one surface of the 1 st connector housing.

When the stopper body is in a correct mounting posture with respect to the 1 st connector housing, the stopper body is accommodated in the stopper body accommodating hole from an opening in one face of the housing.

When the stopper takes an improper posture opposite to normal with respect to the 1 st connector housing, the restricting portion interferes with one surface of the 1 st connector housing, and the stopper cannot be accommodated in the stopper accommodating hole. Therefore, the stopper can be prevented from being attached to the 1 st connector housing in an improper posture. In particular, since the restricting portion is formed continuously with the stopper-side interference portion, the structure of the stopper does not become complicated.

(4) Preferably, the stopper body has a pair of divided portions disposed inside the 1 st connector housing with the recess therebetween, the pair of divided portions each having a through hole communicating with the 1 st cavity at the main locking position, and the stopper body side interference portion is connected to the pair of divided portions.

Since the pair of divided portions are disposed across the concave portion, it may be difficult to ensure the strength of the entire stopper. In this regard, according to the above-described structure, the stopper-side interference portion can function to reinforce the pair of divided portions.

[ Details of embodiments of the present disclosure ]

Specific examples of the present disclosure will be described below with reference to the drawings. The present invention is not limited to these examples, but is defined by the appended claims, and all modifications that come within the meaning and range of equivalency of the claims are intended to be embraced therein.

< Embodiment 1>

As shown in fig. 9, the connector 10 according to embodiment 1 of the present disclosure includes a1 st connector housing 11 and a 2 nd connector housing 12 that can be fitted to each other, a1 st terminal part 13 housed in the 1 st connector housing 11, a 2 nd terminal part 14 housed in the 2 nd connector housing 12, and a stopper 15 attached to the 1 st connector housing 11. The 1 st connector housing 11 and the 1 st terminal fitting 13 are provided in the 1 st connector. The 2 nd connector housing 12 and the 2 nd terminal member 14 are provided in the 2 nd connector. In the following description, the front-rear direction is defined as the front side of the surface on which the 1 st connector housing 11 and the 2 nd connector housing 12 are fitted to face each other. The vertical direction is based on the vertical direction of each of the figures other than fig. 5. The left-right direction is based on the left-right direction of fig. 1-4. The vertical direction and the horizontal direction are synonymous with the height direction and the width direction, respectively. In fig. 1 to 4, the front side is denoted by reference numeral X, the right side is denoted by reference numeral Y, and the upper side is denoted by reference numeral Z. These references of directions do not necessarily coincide with directions in a state where the connector 10 is mounted on a vehicle or the like, not shown.

(2 Nd connector housing, 2 nd terminal part, etc.)

The2 nd connector housing 12 is made of synthetic resin, and includes a 2 nd housing main body 16 having a square block shape and a square tubular cover portion 17 protruding forward from the outer periphery of the2 nd housing main body 16, as shown in fig. 1. The1 st connector housing 11 is fitted inside the cover 17. The cover 17 has a pair of cam followers 18 protruding from the inner surfaces of the upper wall and the lower wall, respectively. Each cam follower 18 has a cylindrical shape, and engages with a lever 19, which will be described later, supported by the1 st connector housing 11 to thereby push the1 st connector housing 11 and the2 nd connector housing 12 into engagement.

The 2 nd housing main body 16 has: a2 nd terminal housing portion 22 having a plurality of 2 nd cavities 21; and a2 nd coaxial terminal accommodating portion 23 provided continuously from an upper side of the 2 nd terminal accommodating portion 22.

The 2 nd coaxial terminal 24 (see fig. 2) is accommodated in the 2 nd coaxial terminal accommodation portion 23. The 2 nd coaxial terminal 24 is arranged in the 2 nd coaxial terminal housing portion 23 in a row in the left-right direction. The 2 nd coaxial terminal 24 is made of conductive metal, and is electrically and mechanically connected to a terminal portion of a coaxial wire (shield wire) not shown. A2 nd front stopper, not shown, is assembled to the 2 nd coaxial terminal housing portion 23 from the front. The 2 nd coaxial terminal 24 is restricted from being separated from the 2 nd coaxial terminal accommodating portion 23 by the 2 nd front stopper.

As shown in fig. 9, the 2 nd terminal fitting 14 is accommodated in the 2 nd terminal accommodation portion 22. The 2 nd terminal fitting 14 is accommodated in the 2 nd cavity 21 of the 2 nd terminal accommodating portion 22 from the rear. The 2 nd terminal member 14 is made of conductive metal, and is electrically and mechanically connected to the terminal portion of the electric wire 27. The 2 nd terminal member 14 has a protruding piece 28 protruding inward of the cover 17. As shown in fig. 2, a movable plate 29 is assembled inside the cover 17. The movable plate 29 is movable in the front-rear direction inside the cover 17, and when it is positioned at the initial position away from the 2 nd terminal housing 22, the distal end portion of the 2 nd terminal member 14 is inserted in a positioned state, thereby protecting the 2 nd terminal member 14.

As shown in fig. 1, the 2 nd connector housing 12 has an anti-tightening portion 31 arranged side by side with each 2 nd terminal member 14 inside the cover portion 17. The tightening prevention portion 31 is formed to protrude forward from the 2 nd terminal housing portion 22. The tip of the tightening prevention portion 31 is disposed forward of the tip of the tab 28 of each 2 nd terminal member 14 inside the cover portion 17. When the 1 st connector housing 11 assumes an inclined posture with respect to the cover 17, the tip of the tightening prevention portion 31 interferes with the 1 st connector housing 11 in the inclined posture, and further fitting of the 1 st connector housing 11 is restricted. This prevents the 1 st connector housing 11 and the 2 nd connector housing 12 from being engaged with each other.

The tightening prevention portion 31 has a plate shape, and includes a horizontal plate portion 32 extending in the left-right direction along the upper end of the front surface of the 2 nd terminal housing portion 22, and a vertical plate portion 33 extending in the up-down direction between the 2 nd cavities 21 on the left and right sides of the front surface of the 2 nd terminal housing portion 22. The 2 nd chambers 21 are disposed on the left and right sides of the vertical plate portion 33. The plate thickness of the vertical plate portion 33 in the left-right direction is larger than the plate thickness of the horizontal plate portion 32 in the up-down direction. The vertical plate portion 33 has a concave evacuation portion 34 for evacuating an erection portion 37 described later at an end portion near the horizontal plate portion 32. The retreat portion 34 extends over the entire length of the vertical plate portion 33 in the front-rear direction, the front end of the vertical plate portion 33 is open, and the rear end is closed by the front surface of the 2 nd terminal housing portion 22. As shown in fig. 10, the upper end portion of the vertical plate portion 33 has a step-shaped reinforcement portion 35 that narrows the height of the retreat portion 34 up and down at the base end portion connected to the 2 nd terminal accommodating portion 22.

As shown in fig. 2, the movable plate 29 has an insertion hole 36 through which the reinforcement portion 35 of the tightening prevention portion 31 can be inserted. The insertion hole 36 has a shape corresponding to the reinforcing portion 35 of the tightening prevention portion 31. The movable plate 29 has a mounting portion 37 that partially closes the insertion hole 36 in a portion corresponding to the evacuation portion 34 on the reinforcement portion 35 side. The mounting portion 37 can be inserted into the retreat portion 34.

The front end of the vertical plate portion 33 has a case-side interference portion 38 below the escape portion 34. The case-side interference portion 38 is formed as an end surface along the up-down direction and the left-right direction at the front end of the vertical plate portion 33.

The 2 nd connector housing 12 has a pair of holding portions 39 protruding forward from the front surface of the 2 nd terminal housing portion 22 on both right and left sides across the tightening prevention portion 31. The holding portions 39 are plate-shaped and are arranged so as to face the plate in the lateral direction. Each holding portion 39 engages the movable plate 29 with a claw portion on the distal end side, and restricts the detachment of the movable plate 29 from the cover 17.

(1 St connector housing, 1 st terminal part, etc.)

The 1 st connector housing 11 is made of synthetic resin, and includes a1 st housing body 41 having a square block shape and a square frame-shaped mounting portion 42 provided continuously to the upper side of the 1 st housing body 41, as shown in fig. 3. As shown in fig. 4, a1 st coaxial terminal accommodating portion 43 (see fig. 10 and 11, since this is located behind a1 st front stopper 46 described later in fig. 4), which is separate from the 1 st connector housing 11, is inserted into the mounting portion 42. The 1 st coaxial terminal not shown is accommodated in the 1 st coaxial terminal accommodation portion 43. The 1 st coaxial terminals are arranged in a row in the left-right direction in the 1 st coaxial terminal accommodating portion 43. The 1 st coaxial terminal is made of conductive metal, and is electrically and mechanically connected to a terminal portion of a coaxial wire (shield wire). The 1 st front stopper 46 is assembled to the 1 st coaxial terminal accommodating portion 43 from the front. The 1 st coaxial terminals are restricted from being separated from the 1 st coaxial terminal accommodating portion 43 by the 1 st front stopper 46.

As shown in fig. 3, the 1 st connector housing 11 has a pair of support shafts 47 protruding from the lower surface of the 1 st housing body 41 and the upper surface of the mounting portion 42, respectively. Each support shaft 47 rotatably supports the lever 19. The lever 19 is made of synthetic resin, and has a pair of plate-shaped cam portions 48 facing each other in the vertical direction and a connecting portion 49 connecting the cam portions 48, as shown in fig. 4. The lever 19 is mounted so as to span the 1 st connector housing 11 in a state in which the support shafts 47 are fitted to the cam portions 48. The cam portions 48 are disposed along the lower surface of the 1 st housing body 41 and the upper surface of the mounting portion 42, and cover the lower surface of the 1 st housing body 41 and the upper surface of the mounting portion 42. At the start of fitting of the 1 st connector housing 11 and the 2 nd connector housing 12, each cam follower 18 enters a cam groove, not shown, of each cam portion 48. When the lever 19 is turned while pinching the coupling portion 49 from this state, the cam followers 18 slide on the groove surfaces of the cam grooves, and the 1 st connector housing 11 and the 2 nd connector housing 12 are fitted. Then, the cam followers 18 reach the rear side of the cam grooves, and the elastic locking portions 51 provided on the lever 19 lock the locking portions 52 (see fig. 1 and 2) provided on the 1 st connector housing 12, so that the 1 st connector housing 11 and the 2 nd connector housing 12 are kept in the fitted state.

As shown in fig. 3, the 1 st housing body 41 has a plurality of 1 st chambers 53. The 1 st chambers 53 are arranged in the 1 st housing body 41 in a vertically and laterally aligned manner at positions corresponding to the 2 nd chambers 21. As shown in fig. 9, the 1 st housing main body 41 has an elastically deformable lance portion 54 protruding from the inner surface of each 1 st cavity 53.

The 1 st terminal part 13 is inserted into the 1 st cavity 53 from the rear, is locked to the lance 54, and is primarily restricted from being released from the 1 st cavity 53 to the rear. The 1 st terminal member 13 is made of conductive metal, and is electrically and mechanically connected to the terminal portion of the electric wire 55 as shown in fig. 9. The 1 st terminal part 13 has a cylindrical connecting portion 56 at a distal end portion thereof, which is locked to the lance portion 54. The tab 28 of the 2 nd terminal member 14 is inserted into the connection portion 56 to be electrically connected to the 1 st connector housing 11 and the 2 nd connector housing 12 when they are fitted.

The 1 st housing main body 41 has an anti-tightening receiving portion 57 that can fit the anti-tightening portion 31 at a position corresponding to the anti-tightening portion 31. As shown in fig. 3, the anti-tightening receiving portion 57 is recessed in the front surface of the 1 st housing main body 41. The anti-tightening receiving portion 57 has a recess 58 disposed between the 1 st cavities 53 in the 1 st housing main body 41 and a recess 59 disposed on the upper side of each 1 st cavity 53, and is opened in a T-shape on the front surface of the 1 st connector housing 11.

The recess 59 opens widely in the left-right direction and the front-rear direction on the upper surface of the 1 st housing body 41, and communicates with the inside of the mounting portion 42. The left and right ends 59A and the rear end 59B of the recess 59 are closed by the edge portions of the upper surface of the 1 st housing main body 41.

The recess 58 extends in the vertical direction at the left and right central portions of the 1 st housing main body 41, and the upper end communicates with the recess 59. Each 1 st chamber 53 is divided left and right through the concave portion 58. In other words, the concave portions 58 extend continuously in the vertical direction with the same width between the 1 st chambers 53 adjacent in the horizontal direction. The lower end 58A of the recess 58 is closed by the lower end of the 1 st housing body 41 located below the 1 st chamber 53 of the lowermost layer. The rear end of the recess 58 is continuous with the rear end 59B of the recess 59 without a step, and is closed by the rear end of the 1 st housing main body 41.

As shown in fig. 8, the 1 st connector housing 11 has a stopper accommodating hole 61 extending in the vertical direction in the front-rear center portion of the 1 st housing body 41 and having a lower end opening on the lower surface (one surface) of the 1 st housing body 41. The stopper accommodating holes 61 intersect the 1 st chambers 53, and intersect the recess 58 at the right and left central portions of the 1 st housing body 41 as shown in fig. 10 and 11.

As shown in fig. 5, the opening of the stopper accommodating hole 61 in the lower surface of the 1 st housing body 41 has a body insertion opening 62 extending long in the left-right direction and a limiting insertion opening 63 extending short in the front-rear direction at the left-right center portion and communicating with the body insertion opening 62 at the front end, and is formed in an asymmetric shape in the front-rear direction. As shown in fig. 10 and 11, the insertion limiting port 63 communicates with the recess 58.

As shown in fig. 3, the 1 st connector housing 11 has a pair of insertion holes 64 penetrating the 1 st housing body 41 in the front-rear direction on both left and right sides across the anti-tightening receiving portion 57. The holding portions 39 of the 2 nd connector housing 12 are inserted into the insertion holes 64 when the 1 st connector housing 11 and the 2 nd connector housing 12 are fitted. The 1 st connector housing 11 has a pair of engaging projections 65 arranged in the vertical direction and projecting from the inner surface of the lower end side of each insertion hole 64.

(Stopper body)

The stopper 15 is inserted into the stopper receiving hole 61 of the 1 st housing body 41 from the lower side. The stopper 15 is movable in the up-down direction with respect to the 1 st connector housing 11 between the temporary locking position and the normal locking position in a state of being accommodated in the stopper accommodating hole 61.

As shown in fig. 6 and 7, the stopper 15 has a plate-like stopper body 66. The stopper body 66 is disposed so as to face the plate in the front-rear direction. The stopper body main body 66 has a plurality of through holes 67 at positions corresponding to the 1 st chambers 53 (except for the 1 st chamber 53 on the uppermost layer). Each through hole 67 has a rectangular opening shape corresponding to the connection portion 56 of the corresponding 1 st terminal member 13. The stopper body main body 66 has a drop-off preventing portion 77 on the front side of the inner lower surface of each through hole 67 and the front side of the upper surface of each divided portion 68 described later. As shown in fig. 9, when the stopper 15 is positioned at the main locking position with respect to the 1 st connector housing 11, the retaining portion 77 is arranged so as to be able to be locked with the 1 st terminal member 13 from the rear, thereby secondarily restricting the 1 st terminal member 13 from being released from the 1 st cavity 53 to the rear.

As shown in fig. 6 and 7, the stopper body main body 66 includes a pair of divided portions 68 divided into left and right sides, and a housing space 69 penetrating in the front-rear direction between the divided portions 68. The through holes 67 are arranged in the pair of dividing portions 68 in the same number. The accommodation space 69 is formed in a rectangular opening shape longer in the vertical direction corresponding to the vertical plate portion 33 of the tightening prevention portion 31, and is disposed at the left and right central portions of the stopper body main body 66. As shown in fig. 10, the vertical plate portion 33 is accommodated in the accommodation space 69 when the 1 st connector housing 11 and the 2 nd connector housing 12 are fitted.

As shown in fig. 6 and 7, the stopper body main body 66 has a connecting portion 71, and the connecting portion 71 is connected between lower end portions of the respective divided portions 68 to close the lower surface of the accommodation space 69. The stopper body main body 66 includes stopper body side interference portions 72, and the stopper body side interference portions 72 are connected between the upper end portions of the divided portions 68 to close the upper surface of the accommodation space 69. When the stopper 15 is located at the temporary locking position with respect to the 1 st connector housing 11, the stopper-side interference portion 72 interferes with the front surface of the housing-side interference portion 38, and the fitting of the 1 st connector housing 11 and the 2 nd connector housing 12 is restricted. The front surface of the stopper-side interference portion 72 continues without steps to the front surface of each of the divided portions 68. The upper surface of the stopper-side interference portion 72 is continuous with the upper surface of each of the divided portions 68 at the same height in the left-right direction. The lower surface of the stopper-side interference portion 72 is disposed at a position overlapping the 1 st chamber 53 of the uppermost layer of the divided portions 68 in the up-down direction along the left-right direction.

As shown in fig. 6 and 7, the stopper body 15 has a restricting portion 73 protruding rearward from the stopper body side interference portion 72 on the rear surface side of the stopper body main body 66. The upper surface of the restricting portion 73 is continuous with the upper surface of the stopper body side interference portion 72 without steps. The restricting portion 73 is formed in a plate shape having a rectangular shape in plan view, and has a plate thickness of the same size as the up-down thickness of the stopper-side interference portion 72. The right-left width of the restricting portion 73 and the right-left width of the stopper-side interference portion 72 are set to be the same. As shown in fig. 5, when the stopper body 15 is inserted into the stopper body receiving hole 61, the stopper body 66 is fitted into the body insertion opening 62, and the restricting portion 73 is fitted into the restricting insertion opening 63.

As shown in fig. 6, the stopper body main body 66 has a pair of rectangular window holes 74 at lower portions of the left and right sides of each divided portion 68. The stopper body 15 has a pair of holding projections 75 in front of each window 74. Each holding projection 75 is formed to stand up from a plate-like portion 76, and the plate-like portion 76 is formed to protrude from the lower end side of the stopper body main body 66. Each holding projection 75 is elastically deformable in the left-right direction. By the holding projections 75 being engaged with the corresponding engaging projections 65, the stopper body 15 is held at the temporary engaging position and the normal engaging position with respect to the 1 st connector housing 11, respectively (see fig. 4 for the temporary engaging position).

(Action of connector)

At the time of assembly, the stopper 15 is inserted into the stopper accommodating hole 61 of the 1 st connector housing 11 from below in a state where the restricting portion 73 faces the rear side of the stopper body main body 66. The stopper body 66 is inserted into the body insertion port 62 (see fig. 5) by inserting the restriction portion 73 into the restriction insertion port 63, so that the stopper body 15 can reach the temporary locking position with respect to the 1 st connector housing 11. In contrast, when the stopper 15 assumes an improper posture (reverse posture) in which the restricting portion 73 is directed to the front side of the stopper body 66, the restricting portion 73 contacts the front side opening edge portion of the body insertion port 62 in the lower surface of the 1 st housing body 41, and the insertion of the stopper 15 into the stopper body accommodating hole 61 is restricted.

When the stopper 15 is in the temporary locking position, as shown in fig. 4, the stopper-side interference portion 72 and the restricting portion 73 are exposed to the inside of the recess 58 and are disposed so as to be visible from the front. In this state, as shown in fig. 8, the 1 st terminal fitting 13 is inserted into the 1 st cavity 53 from the rear of the 1 st connector housing 11. The 1 st terminal part 13 is primarily locked by the lance 54. After the 1 st terminal part 13 is inserted, the stopper 15 moves upward and is disposed at the main locking position. When the stopper 15 is in the normal locking position, the retaining portion 77 is opposed to the connecting portion 56 of the 1 st terminal member 13 from behind, and the 1 st terminal member 13 is locked in the second stage.

Next, the 1 st connector housing 11 is inserted into the cover 17 so as to be shallow, and the fitting of the 1 st connector housing 11 and the 2 nd connector housing 12 is advanced by the turning operation of the lever 19. During the fitting of the 1 st connector housing 11 and the 2 nd connector housing 12, the tightening prevention portion 31 protruding forward from the insertion hole 36 of the driven plate 29 enters the tightening prevention receiving portion 57, the horizontal plate portion 32 is fitted into the recess 59, and the vertical plate portion 33 is fitted into the recess 58. The vertical plate portion 33 is inserted into the accommodation space 69 to avoid interference with the stopper 15 (see fig. 10 which is a side cross section of the vertical plate portion 33 in a vertical direction). When the vertical plate portion 33 is inserted into the accommodation space 69, the stopper-side interference portion 72 enters the escape portion 34, and interference with the tightening prevention portion 31 is avoided. In other words, the case-side interference portion 38 formed at the distal end of the tightening prevention portion 31 avoids interference with the stopper body 15 including the stopper-side interference portion 72 (in fig. 10, refer to a state in which the case-side interference portion 38 penetrates the accommodation space 69 without contacting the stopper body 15).

When the 1 st connector housing 11 and the 2 nd connector housing 12 reach the fitting position, the elastic locking portion 51 of the lever 19 locks the locking portion 52 of the 2 nd connector housing 12, and the 1 st connector housing 11 and the 2 nd connector housing 12 are kept in the fitting state. As shown in fig. 9, the tab 28 of each 2 nd terminal member 14 is inserted into the connection portion 56 of each 1 st terminal member 13, and each 1 st terminal member 13 and each 2 nd terminal member 14 are electrically connected.

Further, when the 1 st connector housing 11 and the 2 nd connector housing 12 reach the fitting position, as shown in fig. 10, the forward protruding portion of the driven plate 29 in the anti-tightening portion 31 is integrally inserted into the anti-tightening receiving portion 57. The stopper-side interference portion 72 is maintained in a state of being disposed inside the escape portion 34. The case-side interference portion 38 is disposed at a predetermined depth (predetermined depth of the fitting position) on the rear side of the recess 58.

In contrast, if the stopper 15 is left at the temporary locking position or if the stopper 15 is left at a position halfway from the temporary locking position toward the main locking position, the stopper-side interference portion 72 is disposed at a position where the case-side interference portion 38 of the tightening prevention portion 31 passes. Therefore, even if the fitting of the 1 st connector housing 11 and the 2 nd connector housing 12 is to be advanced, as shown in fig. 11, the housing-side interference portion 38 interferes with the front surface of the stopper-side interference portion 72 and cannot reach the predetermined depth, and remains at a position shallower than the predetermined depth inside the recess 58. In this way, the fitting of the 1 st connector housing 11 and the 2 nd connector housing 12 is restricted (stopped), and the 1 st connector housing 11 and the 2 nd connector housing 12 do not reach the fitting position, whereby it is possible to detect (recognize) that the stopper 15 does not reach the main locking position with respect to the 1 st connector housing 11.

As described above, according to embodiment 1, the housing-side interference portion 38 interferes with the stopper-side interference portion 72, so that the fitting of the 1 st connector housing 11 and the 2 nd connector housing 12 is restricted, and the stopper 15 can be detected to remain at the temporary locking position or the intermediate position. In particular, according to embodiment 1, the stopper-side interference portion 72 faces the inside of the recess 58, and the recess 58 is formed between the plurality of 1 st cavities 53 in the 1 st connector housing 11, so that the 1 st connector housing 11 is not enlarged by providing the stopper-side interference portion 72, and further enlargement of the connector 10 can be avoided.

Further, since the housing-side interference portion 38 is formed in the tightening prevention portion 31 for preventing the tightening engagement of the connector 10, the structure of the 2 nd connector housing 12 can be simplified, and the enlargement of the connector 10 can be further avoided.

In addition, since the stopper-side interference portion 72 is formed continuously with the restricting portion 73 that restricts the reverse insertion of the stopper 15 with respect to the 1 st connector housing 11, the structure of the stopper 15 does not become complicated.

Further, the stopper-side interference portion 72 is connected to the pair of divided portions 68. Therefore, the stopper-side interference portion 72 can have both the function of detecting the insertion position of the stopper 15 and the function of reinforcing the stopper body main body 66, and can simplify the structure of the stopper 15, and further avoid the enlargement of the connector 10.
