Connection-in-place identifiable anti-loose connector

Abstract

The invention discloses a connection-in-place identifiable anti-loose connector which comprises a housing, a connecting cap and an anti-loose spring, wherein a housing sound-emitting ring which is fixed on the outer wall of the housing and a connecting cap sound-emitting ring which is assembled on the inner wall of the connecting cap in a rotation-stop manner which are adjacent at the front part and the back part are arranged before the anti-loose spring, the back end surface of the connecting cap sound-emitting ring is tightly pushed by the anti-loose spring from the back, and an axial pushing device which is used for transferring pushing force between the plug-in connection end of the connector and the front end surface of the connecting cap sound-emitting ring is axially assembled in an annular cavity before the front end surface of the connecting cap sound-emitting ring in a sliding manner. The connecting cap drives the connecting cap sound-emitting ring to emit sound due to impact friction on the housing sound-emitting ring when being screwed in, when the connecting cap is locked in place, the axial pushing device pushes the connecting cap sound-emitting ring apart, and the sound is eliminated, thereby meeting the normal and reliable connection operation of a user in the no light situation; furthermore, friction of the opposite surfaces of the connecting cap sound-emitting ring and the housing sound-emitting ring can convert the axial force of the spring to the circumferential torque during the relative motion process.

Description

technical field [0001] The invention relates to connectors for signal transmission. Background technique [0002] For some existing connector plugs and sockets, in order to be able to be locked after being mated, a connection cap is generally rotated and sleeved on the plug housing, and the corresponding surface of the connection cap and the adapted socket housing is provided for connection. A locking device that locks each other after the caps are rotated. The locking device can adopt an engaging structure of internal and external threads or a rotatable engaging structure such as an engaging structure of a curved groove and a staple. In order to prevent the locked connecting nut from rotating and loosening under vibration conditions, it is necessary to set an anti-loosening structure on the connector plug to provide an anti-loosening stagnation torque for the connecting nut. The more common anti-loosening structure is to use The spring pressed between the connection cap an...

Problems solved by technology

In addition, the connector also needs to be able to identify whether the axial screw-in of the connecting cap on the socket housing is in place. In the prior art, this problem is solved from a visual point of view by adding a mark line in place on the connector product, and the visual The disadvantage of identification is that it cannot be applied in the absence of light
