Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electric connection box in which a connector can be slidably assembled in a connection box body.

[0002]

[Prior Art]

 FIG. 4 shows a conventional electrical junction box used in a vehicle. The electrical junction box 31 is composed of a synthetic resin junction box body 33 integrally formed with various connector housings 32, and an upper cover 34 and a lower cover 35 for the junction box body 33.

A terminal 37 connected to an electric wire 36 is inserted and accommodated in the connector housing 32 from below, the electric wire 36 is led out from a cutout portion 38 of the lower cover 35, and a relay, fuse, or the like (not shown) is provided from above. And the electric wires (not shown) are led out from the recess 39 of the outer wall of the connection box body 33 along the recess 40 of the lower cover 35.

However, in the above conventional structure, since the connector housing 32 is formed integrally with the connection box body 33, there is no versatility for each vehicle, and the electric connection box 31 is newly provided for each vehicle grade. There was a hassle of having to do it. Further, since it is necessary to attach various types of terminals 37 to various connector housings 32 in the connection box body 33, there is a problem that the terminals 37 are likely to be erroneously attached.

[Problems to be solved by the device]

 In view of the above points, the present invention has an object to provide an electrical connection box that has versatility that can be applied to various vehicle grades and the like and that can prevent incorrect mounting of terminals.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides an opening for connector assembly on one side of a connection box body, and a bottom of the connection box body is formed on the inner wall of the connection box body facing each other from the opening. A pair of slide guides that are parallel to the wall are provided, and flange plates that can engage with the slide guides are provided on the outer periphery of each of the plurality of connectors, and the connectors are connected in a state where the flange plates are abutted against each other. The feature is that it is installed in the box body in a sliding manner.

[0007]

[Action]

 Select a connector according to the vehicle grade, etc., slide the flange plate along the slide guide and assemble it in a proper position inside the junction box body. The terminals are individually mounted in advance in the connector.

【Example】

FIG. 1 shows an embodiment of an electric junction box according to the present invention. The electric junction box 1 has a bottom wall 2 and a junction box body 4 made of synthetic resin having a connector assembly opening 3 on one side, and various connectors 5 ₁ to be assembled from the opening 3. and 5 _2, constituted by a cover 8 for covering an upper opening 7 of the junction box body 4.

The connection box body 4 is provided with a pair of slide guides 10 for assembling a connector in parallel to the bottom wall 2 on both inner sidewalls 9 and 9 facing each other following the side opening 3. A hinge opening / closing lid 11 is integrally provided on the outside of the opening 3. The slide guide 10 has a pair of upper and lower guide plates 10a and 10b closely opposed to each other and a guide groove 10c formed therebetween.

The connector 5₁, 5₂Is a connector housing 12 made of synthetic resin.₁, 12 ₂ A flange plate 13 for sliding engagement with the slide guide 10 on the outer periphery of the₁ , 13₂Is provided so as to project. The flange plate 13₁, 13₂Is engaged at one end₁, 14₂, Engaging recess 15 on the other end₁, 15₂And the flange plate 13₁Engaging recess 15₁The adjacent flange plate 13₂Engaging convex part 14₂Are fitted together, and each connector 5₁, 5₂Are mutually flange plates 13₁, 13₂ Are aligned by butting.

Flexible pieces 16 having locking projections 16a are cut and raised on both sides of each of the flange plates 13 ₁ and 13 ₂ , and the locking projections are formed on the upper guide plate 10a of the slide guide 10. An engagement hole 17 for 16a is provided. The flexible locking piece 16 can be detached by pressing the locking projection 16a from the upper opening 7.

The lid portion 11 is integrally provided with an engaging convex portion 18 for the flange engaging concave portion 15 ₂ of the rear connector 5 ₂ on the inner wall surface, and on the outer side with respect to the engaging protrusion 19 of the outer wall of the connection box body. By providing the engagement frame portion 20 and closing the lid portion 11, it is possible to detect the completion of mounting of the connectors 5 ₁ and 5 ₂ . An engagement recess (not shown) for the engagement protrusion 14 ₁ may be provided on the inner surface of the front wall 21 of the connection box body 4.

In each of the connectors 5 ₁ and 5 ₂ , terminals (not shown) connected to the electric wire 22 are individually attached in advance. Therefore, the terminals can be surely inserted into the connectors 5 ₁ and 5 ₂ without being mistaken. Then, the connectors 5 ₁ and 5 ₂ are sequentially slid in the connection box body 4 with the electric wire 22 being led out. The electric wire 22 is led out to the outside from a notch hole 23 provided in the bottom wall 2. Next, the components such as the relay 24 and the cover 8 are mounted.

In the combination of the connectors, as shown in FIG. 2, it is possible to fill the unnecessary space in the connection box body 4 via the spacer 25 having only the flange plate. A fuse 26 or a fusible link 27 can be connected to the connectors 5 ₃ and 5 ₄ .

Further, as shown in FIG. 3, it is also possible to use the junction box body 29 in which the cover 8 is eliminated and the upper wall 28 is integrally provided. In this case, the relays 24 and the like are previously attached to the connectors 5 ₁ and 5 ₂ and are stored along the slide guide 10 '. This example is suitable for places where waterproofing is required.

[0016]

[Effect of the device]

 As described above, according to the present invention, the combination of connectors can be appropriately changed depending on the grade of the vehicle and the like, so that the connector has versatility and can quickly respond even to a change in configuration. Also, since the terminal can be inserted and inserted in the state of the connector alone, the incorrect insertion of the terminal is prevented and the product quality is stabilized. Furthermore, since the connector can be mounted in a sliding manner, it is possible to improve productivity by automatic assembly.
