Description

[Detailed description of the invention] Conventional connectors are made by inserting and locking the connector into the housing. If a locking failure occurs in which the connectors do not lock properly, and if the mating connectors are connected in this state, proper connection between the connectors will be hindered, resulting in a defect in which the connector function is lost.

The present invention aims to eliminate the above-mentioned defects, and aims to provide a connector that can accurately recognize the above-mentioned poor locking of the connector in the connector, and the connector is formed integrally with the housing. This is applied to a connector that is locked by an elastic locking piece.

Hereinafter, an embodiment of the present invention will be described based on the drawings.A male connector 1 has male connectors 2, 2 facing each other and engaged by elastic locking pieces 3, 3. The elastic locking pieces 3, 3 have bending gaps 6, 6 on the back side and are integrally molded with the housing 7 in a cantilever shape, and the elastic locking pieces 3, 3 have bending gaps 6, 6 on the back side, and are integrally formed with the housing 7. When inserting the flexible gaps 6, 4 until the protrusions 4, 4 fit into the locking holes of the male connectors 2, 2,
6, and when the male connectors 2, 2 are located in the proper position, the protrusions 4, 4 fit into the locking holes, and the elastic locking pieces 3, 3 return to their current positions, and the male connectors 2, 2 are bent in the male connector 1. The position of the male connectors 2, 2 is regulated to complete the locking.

On the other hand, the female connector 11 has female connectors 12, 12 placed back to back, and is engaged by elastic locking pieces 13, 13, and the elastic locking pieces 13, 13 have a bending gap on the back side. 16, which is formed integrally with the housing 17 in the shape of a cantilever, and has elastic locking pieces 3,
3 is bent into the bending gap 16 until the protrusions 14, 14 fit into the locking holes of the female connectors 12, 12 when the female connectors 12, 12 are inserted, and the protrusions 4, 4 are inserted into the locking holes. When inserted, the elastic locking pieces 3, 3 return to their current positions and lock the female connector 1 in the female connector 11.
2 and 12 are performed to complete the locking.

The male connector 1 is provided with a spacer 5 that protrudes from the housing 7 at a position that fits into the bending gap 16 of the female connector 11 when the male and female connectors 1 and 11 are connected. The extended spacers 15, 15 are provided at positions where they fit into the bending gap of the male connector 1 when the male and female connectors 1, 11 are connected.

In the above configuration, when the male connector 2' is positioned at an inappropriate position due to insufficient insertion as shown in FIG. 2 and a locking failure occurs, the elastic locking piece 3 is bent in the direction of the bending gap 6 Therefore, even if an attempt is made to connect the male and female connectors 1, 11, the tip of the spacer 15 and the free end of the elastic locking piece 3 will come into contact and interfere, causing the male and female connectors 1, 11 to become deformed. The coupling is completely prevented, and a locking failure due to insufficient insertion of the male connector 2 can be accurately recognized.

Further, as shown in FIG. 3, when the female connector 12' is placed in an incorrect position due to insufficient insertion and a locking failure occurs, the elastic locking piece 13 becomes deformed in the direction of the bending gap 6. , therefore male and female connector 1,
11, the tip of the spacer 5 and the free end of the elastic locking piece 13 come into contact and interfere,
The coupling of the male and female connectors 1 and 11 is completely prevented, and a locking failure due to insufficient insertion of the female connector 12 can be accurately recognized.

If the male connectors 2, 2 in the male connector 1 and the female connectors 12, 12 in the female connector 11 are located in the proper position and properly locked, the male connector 1 will open as shown in FIG. The spacer 5 fits into the flexible gap 16 of the male connector 11, and the spacers 15, 15 of the female connector 11 fit into the flexible gaps 6, 6 of the male connector 1, so that the male and female connectors 1, 11 are connected. It is done smoothly.

As described above, in the present invention, the flexible gaps 6, 6 of the male connector 1 are provided radially outward of the elastic locking pieces 3, 3, and the housing of the female connector 11, which is a mating connector, is provided in the flexible gaps 6, 6. Since the spacers 15, 15 are provided extending from the outer wall of the connector 17, the distance between the guide surfaces when the male and female connectors are fitted into each other can be increased, and the male and female connectors can be prevented from being twisted together.
