A connector and its plug

Abstract

The invention relates to a connector and a plug thereof. The plug of the connector comprises a housing and a connecting screw cap mounted on the housing, The plug-in end of the housing is provided with a ring table. The ring table is provided with a stop surface for stop-fitting the connecting screw cap in the axial direction. An elastic member for elastically pressing the connecting screw cap onto the stop surface is arranged between the housing and the connecting screw cap. A corrugated convex-concave structure extending along the circumferential direction is formed between the ring table and the connecting screw cap. When the plug of the connector is plugged into the socket, the elastic member elastically pushes the connecting screw cap against the stop surface of the ring table to provide axial pretension for the connecting screw cap so as to reduce the possibility of return of the connecting screw cap. Besides, loosening of the connecting screw cap needs to overcome the resistanceof the corrugated convex-concave structure between the ring table and the connecting screw cap and the loosening difficulty of the screw threads is increased so that anti-loosening of the connectingscrew cap can be realized even when the corrugated spring deformation amount is low and the reliability and the stability of the connector can be ensured.

Description

technical field [0001] The invention relates to a connector and its plug. Background technique [0002] In the field of connectors, it is very common to use a connecting nut to lock the plug and the socket. Such as figure 1 As shown, most connectors are provided with an O-ring 3 at the junction of the plug 1 and the socket 2, and the pre-tightening force of the O-ring 3 is used to prevent loosening, but the pre-tightening force of the O-ring is small , The anti-loosening effect is not good. [0003] The announcement date is CN102751617B, and the Chinese patent on August 26, 2015 discloses an anti-loose threaded connector and its components. Connecting the nut, a corrugated spring is sheathed on the socket part of the housing, and a card slot is provided on the outer peripheral surface of the socket part, and a corrugated spring is carded in the card slot. When the plug and the socket are mated, the corrugated spring The groove wall of the annular groove on the top pressu...

Problems solved by technology

[0005] The purpose of the present invention is to provide a connector plug, which solves the problem that the connector plug in the prior art is easy to loosen from the socket in a vibration environment, and the anti-loosening effect is poor; the purpose of the present invention is also to provide a kind of connector
