Description

[Detailed Description of the Invention] The present invention relates to a connector locking mechanism for reliably locking a pair of connectors together.

Conventionally, in order to connect a pair of electrical connectors, an insertion member having a connecting piece and a claw portion is provided on one connector, and the lock is locked by cooperation with a frame portion of a receiving member provided on the other connector. Mechanisms are widely used.

However, depending on the dimensions of the connector, it may be necessary to lengthen the connecting piece of the insertion member, and in that case, the insertion member may not be in the desired position due to shrinkage of the material during molding. They may form in unstable positions.

Then, during use, there was a risk that the locking mechanism would come off due to, for example, the posture of the connector or unexpected acceleration.

The purpose of the present invention is to prevent the above-mentioned accidents by suspending the insertion member by a support member, thereby eliminating irregularities during molding, and furthermore, to improve the reliability of the locking action during use. Our goal is to provide a mechanism for
The content is a connector in which an insertion member attached to one of a pair of connectors is inserted into a frame attached to the other connector, and a claw at the tip of the insertion member is hooked to the frame. In the locking mechanism, a strip-shaped support piece having elasticity in the vertical direction is provided above the insertion member almost parallel to the insertion member, and the support piece is attached to a bridge constructed between both side walls of the connector body. It is characterized in that it is integrally connected to the connector main body via a connecting part, and the support piece and the intermediate part of the insertion member are connected, so that the insertion member is elastically suspended by the support piece. be.

The present invention will be explained in detail based on illustrated embodiments.

In the drawing, 1 is an insertion member attached to a female connector 2 made of synthetic resin, for example, and 3 is a male connector 4 made of the same material.
This is a receiving member that is attached to the insertion member 1 and has a locking function in cooperation with the insertion member 1.

In the insertion member 1, a claw portion 7 that engages with the frame portion 6 of the receiving member 3 is provided at the tip of a strip-shaped connecting piece 5 that extends forward from the main body of the connector 2 and is elastic in the vertical direction. There is.

The tip of the claw part 7 has a slope part 8 to facilitate insertion into the frame part 6, and the rear side thereof has a back part 9 cut almost vertically, and a rear wall part 10 of the frame part 6 is formed on the rear side. It can be locked to.

In the connector 2, side walls 11 and 12 are further provided on both sides of the insertion member 1 from the main body, and the connecting piece 5 is connected from a bridge section 13 constructed between the front ends of the side walls 11 and 12. A strip-shaped support piece 14 having elasticity in the vertical direction extends upwardly and substantially parallel to the connecting piece 5 .

The supporting piece 14 and the intermediate portion of the connecting piece 5 on the protruding side of the claw portion 7 are connected by a rib 15 .

In order to couple the insertion member 1 and the receiving member 3 and have a locking effect, it is sufficient to fit the connectors 2 and 4 together and insert the insertion member 1 into the frame 6 of the receiving member 3. However, at that time, the slope part 8 of the claw part 7 at the tip of the connecting piece 5 is guided into the inner hole of the frame part 6 of the receiving member 3, and the connecting piece 5 and the rib 1
Although the support piece 14 connected by 5 is not bent downward,
The claw portion 7 will pass through the frame portion 6.

When the claw portion 7 passes through the frame portion 6, the connecting piece 5 and the supporting piece 14
Due to the restoring force, the connecting piece 5 returns to its original position, and the rear surface 9 of the claw portion 7 engages with the rear wall portion 10 of the frame portion 6, thereby locking the connecting piece 5 as shown in FIG. 3.

With this locking, the electrical connection members (not shown) housed inside the respective connectors 2 and 4 are electrically connected to each other.

The embodiment shown in FIG. 4 is a metal male connector 4' which also serves as an electrical connection member, and its tip 16 is a tongue-shaped insertion terminal.

This connector 4' is provided with a receiving member 3' consisting of a frame portion 6', similar to the connector 4 shown in FIG. It will be done.

Since the elastic force of the support piece 14 is added to the original elastic force of the connecting piece 5, it becomes an extremely strong elastic force, and is almost uncoupled by an untimely force other than an external force caused by the intention to release the lock. Never.

Furthermore, the presence of the support piece 14 also plays the role of suspending the connecting piece 5 during molding, so that the connecting piece 5 is prevented from solidifying while being deformed, and the connecting piece 5 is molded into a predetermined shape. Therefore, the locking effect can be made more reliable.

In the embodiment, the support piece 14 extends from the front of the connection piece 5, but the effect will still be the same even if the support piece 14 extends from the rear of the support piece 14 and the connection piece 5 toward the front. There is no difference in effect.

As explained above, since the locking mechanism of the connector according to the present invention is suspended by a support piece having a conventional insertion member, the dimensional accuracy during molding is more accurate, and furthermore, the elastic force of the insertion member is strengthened. This has the advantage of preventing unintentional dissociation in the bonded state.
