Plug, socket and high-voltage interlocking connector assembly

Abstract

The invention relates to a plug, a socket and a high-voltage interlocking connector assembly. A plug housing is provided with a first locking piece, one end, which is oriented towards the socket, of the first locking piece is provided with a lock hook, a socket housing is provided with a lock catch in hooking cooperation with the lock hook, and the other end of the first locking piece is an unlocking end; the plug housing is also provided with an elastic cantilever, the lower end of the suspension extending end of the elastic cantilever is provided with a lock block, the socket housing is provided with a block in stopping cooperation with the lock catch in an insertion direction, and when the elastic cantilever is compressed, the elastic cantilever drives the lock block to move downwards and can be staggered from the block so as to go beyond the block; and when the lock hook hooks the lock catch, there is a certain distance between the lock block and the block in the insertion direction. The high-voltage interlocking connector assembly realizes secondary separation of the plug and the socket through the first locking piece and the elastic cantilever, the structure is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to a conductive connection device, in particular to a plug, a socket and a high-voltage interlock connector assembly. Background technique [0002] The high-voltage interlock connector is a key component of the high-voltage electrical system, which is mainly used to conduct high-voltage circuits. In order to ensure that the internally connected high-voltage circuit will not cause danger to operators when the plug and socket are separated from each other, an interlock structure is generally required to disconnect the high-voltage circuit in advance when the plug and socket are separated. [0003] For example, the Chinese utility model patent with the authorized announcement number CN203415738U and the authorized announcement date of 2014.1.29 discloses a high-voltage interlock connector. The plug housing of this connector is provided with primary and secondary locks. It is hinged outside the plug housing, and a spring is provided ...

AI Technical Summary

Problems solved by technology

[0004] Although this high-voltage interlock connector ensures the safety when the plug and socket are unplugged through two locks, the primary lock is hinged and connected with a spring, and the secondary lock needs to be rotated to the same level as the primary lock during assembly. A limit structure is set at the positions where the locks offset and stagger, and there is a transmission relationship between the secondary lock and the internal contact, which leads to a very complicated structure of the entire connector and high manufacturing and assembly costs
