Ratchet push-pull self-locking electric connector

Abstract

The invention discloses a ratchet push-pull self-locking electric connector which comprises a plug assembly and a socket assembly. The front end of a plug shell is movably sleeved with a locking ring,a ratchet is movably installed on the locking ring, a positioning block is installed on the outer side wall of a head shell, a positioning sleeve is fixed to the outer side wall of the rear end of the head shell, and the outer portion of the positioning sleeve and the outer portion of the locking ring are sleeved with push-pull rings. A positioning block matching groove is formed in a push-pull gear of the push-pull ring, the ratchet wheel is provided with four continuous ratchets, the socket assembly comprises a seat shell and a needle insulator, a long-strip constraint block is arranged onthe inner side wall of the seat shell, a locking bottom plate is further arranged on the inner side wall of the seat shell, and a locking gap is formed between the end of the long-strip constraint block and the locking bottom plate. The front end of the locking ring is provided with an outwards-turned round step plate, and the outwards-turned round step plate is provided with a restraining edge. Locking and unlocking operations are jointly realized by combining a plug-in position relationship between the plug and the socket and a position relationship that the push-pull ring pushes the ratchetwheel, the purpose of push-pull and direct-plug operation self-locking is realized, and the electric connector has the advantages of long service life, reliable performance and the like.

Description

technical field [0001] The invention relates to an electrical connector, in particular to a ratchet push-pull self-locking electrical connector. Background technique [0002] The electrical connector includes a plug and a socket, which is a combined structure that realizes the electrical insertion of the plug and the socket. After the plug is inserted into the socket, it will be affected by the vibration of external equipment during use, which will cause the plug to withdraw from the socket. The traditional method is to lock the connection with threads, buckles or snap locks, which often requires additional locking parts. This increases the difficulty of installation, and sometimes causes no dedicated space to install the locking structure. The operation of the locking and unlocking process is relatively complicated, and is easily restricted by the assembly environment. In recent years, the straight-plug fast push-pull self-locking method has become a research direction, so...
