Abstract

PURPOSE:To facilitate the mutual engagement and removal each multipolar connector by utilizing a connector supporting plate as a lever. CONSTITUTION:A connector supporting plate 4 is positioned under a connector holding plate 3, and a turning shaft 15 of the supporting plate 14 is fitted in a bearing 7 of the holding plate 3. A connector 5 and a housing 6a are arranged opposite to each other, and the force is applied to a part near a locking claw 16 of the supporting plate 4 to turn the supporting plate 4. The connector 5 is thereby led into the housing 6a, and the both are engaged with each other, and simultaneously, the claw 6 is fitted in a locking recessed part 9 of the holding plate 3 to lock the holding plate 3 with the supporting plate 4. At this stage, since the turning shaft 15 of the supporting plate 4 is slid inside a U-like groove of the bearing 7 and the housing 6a can be oscillated around an oscillation shaft 12, each terminal of the connector 5a and the housing 6a are engaged with each other, holding an appropriate position.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector mainly used for connecting a wire harness for an automobile, in which the inserting / withdrawing force of the connector is reduced to improve the workability of the connector fitting process.

[0002]

2. Description of the Related Art Generally, a wire harness has a structure in which a branch line is led out from a main line portion in which a large number of electric wires are bundled,
A female or male connector provided at the end of the branch line makes electrical connection with various electrical components. Female like this,
In the connection method using a male connector, a large number of switches and meters are concentrated in a part such as an instrument panel of a car, where a large number of connectors are present, which makes the connection complicated and requires a huge occupied space. Will be.

Therefore, as shown in FIG. 7, a high-density multipolar connector K provided with a large number of terminal accommodating chambers has been proposed (Japanese Patent Laid-Open No. 62-145673). However, in such a high-density multi-pole connector K, since the number of terminals to be accommodated is extremely large, the mating with a mating connector (not shown) and the withdrawal are performed by tightening the bolt a. Since a tool must be used, the workability of the fitting process is extremely poor.

Further, a connector whose mechanical force such as a lever is used to reduce the insertion / removal force requires a space for accommodating a mechanical component such as a lever, so that the connector cannot be made thin and lightweight. have.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a thin and lightweight connector having a low insertion / removal force and excellent workability in the fitting process. To do.

[0006]

To achieve the above object, the present invention provides a connector holding plate provided with one connector of a pair of connectors fitted to each other and a connector holding plate for supporting the other connector in a swingable manner. A connector supporting plate, the connector holding plate and the connector supporting plate are rotatably and slidably engaged with each other, and the connector supporting plate is rotated and slid to fit the connector. It is characterized in that it is removed.

[0007]

According to the present invention, since the connector holding plate and the connector supporting plate are rotatably and slidably attached to each other, the connectors provided on the connector holding plate and the connector supporting plate are fitted and removed from each other. In this case, the connector support plate rotatably attached to the connector holding plate acts as a lever to reduce the force required for fitting and removal, and the connector support plate slides to prevent the terminals in the connector from sliding. The mutually opposed positions are held, and the terminals can be smoothly fitted to each other. Further, since the connector holding plate and the connector supporting plate can be formed thin, the components including the connector can be made thin and lightweight.

[0008]

EXAMPLE As an example of the present invention, as shown in FIG.
The low insertion / removal connector A applied to the relay board 1a of the main wire harness 1 and the branch board 2a of the branch wire harness 2 will be described. The low insertion / removal connector A includes a connector holding plate 3 that forms the relay board 1 a of the main wire harness 1 and a connector support plate 4 that forms the branch board 2 a of the branch wire harness 2. Is attached with one connector 5 of a pair of connectors fitted to each other, and the other end of the connector support plate 4 is provided with the other connector 6 corresponding to the connector 5 swingably.

A bearing portion 8 having a bearing 7 having a U-shaped groove is erected at one end of the connector holding plate 3.
Locking recesses 9 are formed on both side walls of the other end.
Support legs 10 for supporting the other connector 6 are provided on both edges of one end of the connector support plate 4, respectively. As shown in FIG. The connector 6 is swingably supported by inserting the swing shaft 12 provided on the side of the housing 6a of the connector 6.

In the housing 6a of the connector 6, FIG.
, A plurality of male terminals 13 are fixed,
The wire 14 is loosely connected to the electric wire 14 disposed in the relay board 1a. On the outside of the support leg 10, the rotation support portion 4 is provided.
a is provided and supports a rod-shaped rotating shaft 15 that engages with the bearing 7 of the connector holding plate 3.

Locking claws 16 are provided on both edges of the other end of the connector supporting plate 4 to engage with the locking recesses 9 of the connector holding plate 3 to engage the connector holding plate 3 and the connector supporting plate 4. I'm trying to stop.

Next, the step of fitting the connector 5 and the connector 6 will be described. First, as shown in FIG. 4, the connector support plate 4 is positioned below the connector holding plate 3, and the rotating shaft 15 of the connector support plate 4 is brought close to the bearing 7 of the connector holding plate 3 as shown by the arrow. To engage each other.

Then, as shown in FIG. 5, the connector 5 and the connector 6 are opposed to each other, and a force is applied to the vicinity of the lock claw 16 of the connector support plate 4 to rotate the connector support plate 4 in the direction shown by the arrow. , The connector 5 is introduced into the housing 6a of the connector 6 to fit them together, and the lock claw 1
6 is engaged with the locking recess 9 of the connector holding plate 3 to lock the connector holding plate 3 and the connector supporting plate 4 as shown in FIG.

At this time, the rotating shaft 15 of the connector support plate 4
Slides in the U-shaped groove of the bearing 7 and the connector 6 can swing about the swing shaft 12, so that the terminals of the connector 5 and the connector 6 are fitted while maintaining proper positions. Are combined.

In the above embodiment, the case where the present invention is applied to the relay board or the like which constitutes the wire harness has been described, but the present invention is not limited to this, and is used as an independent connector for electric wiring. You can do it.

[0016]

According to the present invention, the mutual fitting of the connectors,
When the connector is removed, the connector support plate acts as a lever, so that the force required for fitting and removing is reduced, and even a multipolar connector having a large number of terminals can be easily inserted and removed. Also, the connector holding plate and the connector support plate are
Since it can be formed thin, and it can also serve as a relay board of a wire harness or a branch board of a branch wire harness, there is an advantage that the wire harness including the connector can be made thinner and lighter. .
