Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connector, and more particularly, to a reliable positioning of a terminal in a housing of the connector.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 6 (A), a housing 1 of a connector for a flat cable or a ribbon wire is formed of a synthetic resin into a rectangular shape, and a terminal 2 made of a thin plate is inserted into the housing 1. The slit-shaped terminal receiving holes 1a are formed in the width direction at a constant pitch.

In the terminal 2, the contact piece 2a protruding in parallel to the horizontal direction and the rear end of the positioning piece 2b are connected by a connecting portion 2e, and a lead piece 2c protruding rearward is formed at the lower end of the connecting portion 2e. In addition, it has a substantially fork shape, and an upward fixing projection 2d is formed on the upper edge portion of the positioning piece 2b.

When the contact piece 2a and the positioning piece 2b of the terminal 2 are inserted into the contact piece groove 1b and the positioning piece groove 1c of the terminal receiving hole 1a of the housing 1, respectively, the fixing projection 2d of the positioning piece 2b is inserted into the intermediate wall 1d. The terminal 2 is cut into the lower surface to prevent the terminal 2 from falling off, and the terminal 2 is fixed in the terminal receiving hole 1a.

Further, as shown in FIG. 6B, fixing protrusions 2d, 2d are formed on the upper edge portion of the contact piece 2a of the terminal 2 and the lower edge portion of the positioning piece 2b, respectively. There is also one in which the lower surface of the wall 1e and the upper surface of the lower wall 1f are engaged with each other to prevent them from coming off.

[0006]

[Problems to be solved by the device]

 However, in the fixing structure of the terminal 2 by the fixing protrusion 2d, although the fixing protrusion 2d has a function of preventing the fixing protrusion 2d from being removed, since the housing 1 side is not provided with a groove or the like with which the fixing protrusion 2d engages, There is no function to position the insertion position of terminal 2. Therefore, when the terminal 2 is inserted, there is a problem that the insertion position is likely to vary and the contact pressure of the cable changes if the insertion position shifts. Further, since the connecting portion 2e of the terminal 2 is inserted into the terminal receiving hole 1a, it is difficult to determine the deviation of the insertion position.

The present invention has been made to solve the above problems, and an object of the present invention is to reliably position a terminal in a housing of a connector.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a connector in which a fork-shaped terminal in which a contact piece and a rear end of a positioning piece are vertically connected by a connecting portion is inserted into a slit-shaped terminal receiving hole formed in a housing. Engagement protrusions are formed on the upper and lower ends of the connecting portion of the terminal, and the engagement protrusions are fitted on the upper and lower parts of the terminal receiving hole of the housing to regulate the most advanced position for inserting the terminal. The present invention provides a connector having engagement slits formed therein.

[0009]

[Action]

 According to the present invention, when the terminal is inserted, the engaging protrusions formed on the upper and lower ends of the connecting portion of the terminal are inserted into the engaging slits formed on the upper and lower portions of the terminal receiving hole of the housing to be locked. Therefore, the most advanced position of insertion of the terminal is accurately controlled. This ensures that the terminal can be positioned in the housing.

[0010]

【Example】

 Hereinafter, the present invention will be described in detail with reference to illustrated embodiments. As shown in FIG. 2 and FIG. 4, the fork-shaped thin plate terminal 12 has a contact piece 12a and a positioning piece 12b formed in the front part, and the rear end of the contact piece 12a and the positioning piece 12b is connected to the connecting part 12g. Are connected with.

The upper and lower edges of the connecting portion 12g of the terminal 12 are respectively provided with an upper engaging projection 12e and a lower engaging projection 12f at substantially the same height as the height of a housing 11 described later. Has been formed. Further, the lead piece 12c is provided so as to project in the horizontal direction from the rear surface of the lower engaging projection 12f. An upward fixing protrusion 12d is formed on the upper edge of the positioning piece 12b.

On the other hand, in the housing 11 made of synthetic resin, slit-shaped terminal receiving holes 11a into which the terminals 12 are inserted are formed at a constant pitch in the width direction. The terminal receiving hole 11a is formed with a contact piece groove 11b and a positioning piece groove 11c which are partitioned by an intermediate wall 11d. A slide member 13 is inserted into the terminal receiving hole 11a of the housing 11 from the side opposite to the terminal 12.

The upper engaging protrusions 12e and the lower engaging protrusions 12f of the terminal 12 are respectively inserted and fixed to the upper wall 11e and the lower wall 11f of the terminal receiving hole 11a of the housing 11 on the terminal insertion side. The upper engaging slit 11g and the lower engaging slit 11h are formed with a constant depth.

With the above structure, when the contact piece 12a and the positioning piece 12b are inserted into the contact piece groove 11b and the positioning piece groove 11c of the terminal receiving hole 11a of the housing 11, respectively, when the terminal 12 is inserted, the terminal 12 is inserted. The fixing projection 12d of the positioning piece 12b bites into the lower surface of the intermediate wall 11d and is prevented from coming off, and the terminal 12 is fixed in the terminal receiving hole 11a.

At the same time, as shown in FIGS. 1 and 5, the upper engaging protrusions 12e and the lower engaging protrusions 12f of the terminal 12 are inserted into the upper engaging slits 11g and the lower engaging slits 11h of the housing 11, respectively. Can be stopped.

As a result, the most advanced insertion position of the terminal 12 is accurately regulated, and the terminal 12 is reliably positioned in the housing 11. Therefore, the insertion position of the terminal 12 does not vary, and the contact pressure of the cable does not change. Further, as shown in FIGS. 1 and 5, since the engaging protrusions 12e and 12f of the terminal 12 are visible from the outside of the housing 11, it is possible to easily determine the deviation of the insertion position.

As shown in FIG. 3, fixing projections 12d and 12d are formed on the upper edge portion of the contact piece 12a and the lower edge portion of the positioning piece 12b of the terminal 12, respectively. It goes without saying that the present invention can also be applied to a type in which the upper surface of the wall 11d is engaged with each other to prevent the wall from coming off.

[0018]

[Effect of device]

 As is clear from the above description, in the connector of the present invention, when the terminal is inserted, the engaging projection of the terminal is inserted into the engaging slit of the housing to be fixed, so that the most advanced position of inserting the terminal is accurate. The terminal can be reliably positioned in the housing. Therefore, the insertion position of the terminal does not vary and the contact pressure of the cable does not change. Further, since the engaging protrusions of the terminal can be seen from the outside of the housing, it is possible to easily determine the deviation of the insertion position.
