Short circuit preventing socket and electric connector

Abstract

The invention provides a short circuit preventing socket and an electric connector. The short circuit preventing socket comprises a front layer (11), a back layer (10), a shell (4) and a lock mechanism, wherein the lock mechanism comprises a lock rod (1), a first steel ball (14), a positioning sleeve (2), a special-shaped lock block (13), a baffle ring (5), a first spring (6) and a spring seat (8); a plug is provided with an unlocking sleeve (18); the unlocking sleeve is provided with a second groove (19) which is matched with the first steel ball (14) so as to achieve the unlocking of the front layer (11); the end surface of the unlocking sleeve (18) can push the special-shaped lock block (13) to move, so as to achieve the unlocking of the front layer. According to the invention, a simple manner is adopted to achieve the locking and unlocking of the front layer of the socket.

Description

Technical field [0001] The invention relates to an electrical connector, in particular to a separate and detachable electrical connector. Background technique [0002] Most foreign separate and disconnected electrical connectors use pull-wire separation mechanisms, such as the J599 / 29 and J599 / 30 pull-wire separation electrical connectors of the MIL-DTL-38999 series. The socket is MIL-DTL-38999 series standard socket. The socket is a single-layer structure without an active layer. After separation, the internal electrical signal of the socket cannot be disconnected. To realize the function of preventing short-circuit, the socket is generally shielded by another mechanism , Through the baffle to realize the function of preventing short circuit or flame. [0003] Domestic separate sockets, in order to achieve short-circuit or flame-proof functions, most of them have a double-layer structure (front layer and back layer, with a separation spring in the middle). After separation, the i...

AI Technical Summary

Problems solved by technology

[0003] Domestic separation sockets, in order to realize short-circuit prevention or flame prevention functions, mostly have a double-layer structure (front layer and back layer, with a separation spring in the middle), which can disconnect the internal electrical signal of the socket after separation, such as YF6-57ZK products , but the front layer of the socket is suspended inside the socket housing and cannot be self-locked, and the front layer does not have the function of preventing short circuit

The product with the anti-short-circuit function of the front layer is YF9-57ZK, and the front layer is not self-locking. Under water or under high pressure, the front layer will move axially, and the electrical signal inside the socket will be connected again, resulting in Anti-short circuit failure
