Secondary locking mechanism and secondary locking connector

Abstract

The invention relates to a secondary locking mechanism and a secondary locking connector. The secondary locking mechanism comprises a socket shell, a plug shell and a secondary locking block; a first stop block, a second stop block and an auxiliary protruding block are arranged on the socket shell; the plug shell is provided with a main lock hanging table and a guide hole, and the main lock hanging table is provided with a first hook and a second hook; a cantilever capable of being inserted into the guide hole is arranged on the secondary locking block, and a hook protruding block is arranged on the cantilever; when the socket shell and the plug shell are locked, the first hook is locked on the first stop block, and the hook protruding block penetrates through the guide hole to be locked on the auxiliary protruding block; and when the socket shell is separated from the plug shell by a preset distance, the second hook is locked on the second stop block. According to the secondary locking mechanism and secondary locking connector, the functions of main lock locking, delayed unlocking and secondary locking are achieved through combination of simple structures. The moment arm of the secondary locking block is inserted into the guide hole in the plug shell, so that the secondary locking block can be prevented from moving due to misoperation, and the problem of mistaken unlocking is avoided. With the secondary locking mechanism and secondary locking connector adopted, the problem that an existing connector is insufficient in reliability and safety is solved.

Description
