Locking sheet, push-and-pull locking mechanism and connector with push-and-pull locking mechanism

Abstract

A push-and-pull locking mechanism comprises a locking sheet, a movement member, a protruded part, an elastic member and a limiting member. The locking sheet is mounted on a socket casing or a plug casing in a rotatable connection manner; the movement member mounted on the socket casing or the plug casing and capable of moving horizontally relative to the socket casing or the plug casing; the protruded part is arranged in the end portion of the movement member, cooperates with an inclined surface of a cooperation part by abutting, and enables the locking sheet to rotate when a socket is separated from a plug; one end of the elastic member is connected with the locking sheet, the other end of the elastic member is connected with the socket casing or plug casing, and the elastic member enables the locking sheet to return to the original position automatically after rotation; and the limiting member is mounted on the socket casing or plug casing, and limit horizontal movement of the movement member. When the push-and-pull locking mechanism is used to lock the socket and plug, it is only required to insert the plug into the socket, and when the socket is separated from the plug, it is only required to pull the movement member; and compared with the prior art, operation is simple, dismounting steps can be reduced, and the working efficiency is improved. The locking sheet and movementmember can both return the original positions after operation.

Description

technical field

[0001] The invention belongs to the technical field of connectors, and in particular relates to a locking piece, a push-pull locking mechanism using the locking piece and a connector using the push-pull locking mechanism. Background technique

[0002] In the prior art, the locking of the socket and the plug is realized by manually operating the locking piece. see Figure 1A to Figure 1C , the existing locking piece 2 has two connecting arms 201 arranged oppositely, and a bridging portion 202 connecting the aforementioned two connecting arms. The other end 2011 is hinged with the first protrusion 101 on the socket housing and is close to the plug housing 3 for matching with the second protrusion 301 on the plug housing; When locking the socket and the plug, the end of the connecting arm close to the socket housing is sleeved on the first protrusion on the same side of the socket housing, so that the locking piece straddles the socket and can be positioned rel...
