Description

electrical connector

【Technical field】

The utility model relates to an electrical connector, in particular to an electrical connector with a pull rod and a pair of clasps.

【Background technique】

US Patent No. 5,564,939 discloses an electrical connector, which has a pair of clasps 22 and 22A, and the pair of clasps are respectively held on two sides of the electrical connector body 21 . The operation part 23 has a pair of cams 23-4 located on the curved part 22-4 of the hooks 22, 22A. When the operating portion of the pull rod is pulled backward, the cam 23-4 exerts an outward force on the curved portion 22-4 to disengage the U-shaped hook portion 22-1 from the docking connector. Since the operating part 23 and the clasps 22 and 22A are installed outside the main body 21, they are easily damaged when an external force is applied thereon. When two or more connectors are arranged side by side, a relatively large space is required between the two connectors, which is not conducive to saving the space of the electrical system in which such connectors are installed. In addition, when the pulling force on the operating portion 23 is removed, the clasps 22 and 22A will generate elastic force to drive the operating portion 23 back to its original position. However, the elastic force is too small to return the operating portion 23 to its original position. In order to overcome the above drawbacks, it is necessary to provide an electrical connector in which the pull bar can be automatically returned.

【Content of invention】

The main purpose of the utility model is to provide an electrical connector whose pull rod can automatically return to its position.

In order to achieve the above purpose, the utility model adopts the following technical solutions: the utility model electrical connector includes a base, a metal shrapnel, a connector part, a pair of clasps, a pull rod and a cover; The shrapnel is assembled on the base, the connector part is assembled on the base and a part of it extends into the docking frame, the clasp is assembled on the opposite sides of the base and can deflect laterally, the pull rod is assembled on the base, which has a For the lock release part, when the pull rod is pulled backward, the lock release part pushes the clasp to deflect laterally, and the shrapnel produces elastic deformation. After the pull rod is released, the shrapnel exerts elastic force on the pull rod to return the pull rod and the buckle to their original positions.

Compared with the prior art, the utility model uses the elastic device to automatically return the pull rod and the clasp, which is convenient to operate and high in assembly efficiency, thereby reducing the manufacturing cost.
