Pull-off electrical connector assembly labor-saving in plugging

Abstract

The invention relates to the field of electrical connectors, and especially relates to a pull-off electrical connector assembly labor-saving in plugging. The pull-off electrical connector assembly labor-saving in plugging comprises a plug and a socket which respectively take the front end as a plugging end. The plug comprises a plug housing and a connecting cap rotatably assembled on the plug housing. The connecting cap is in anti-play fit with the plug housing along the axial direction through a retaining wall arranged on the connecting cap, and the front side of the retaining wall is in rolling fit with the plug housing through a rolling body. In the pull-off electrical connector assembly labor-saving in plugging, as the front side of the retaining wall of the connecting cap of the plug is in rolling fit with the plug housing through the rolling body, sliding friction between the connecting cap and the housing of the existing pull-off electrical connector is converted into rolling friction, and the purpose of reducing the plugging resistance of the existing pull-off electrical connector is achieved.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a plug-in and labor-saving pull-off type electrical connector assembly. Background technique [0002] The pull-off electrical connector assembly is a relatively common type of electrical connector. The electrical connector assembly includes a plug and a socket. The plug includes a plug housing, a plug contact piece assembled in the plug housing through a plug insulator, and a fixed assembly The mandrel locking mechanism in the plug housing, the mandrel locking mechanism includes a shaft sleeve, a mandrel worn in the shaft sleeve, a spring sleeved on the mandrel and a steel ball arranged on the shaft sleeve, and the socket includes The socket housing, the socket contacts assembled in the socket housing through the socket insulator and the locking ring fixedly arranged on the socket insulator, when the plug is mated with the socket, the mandrel locking mechanism cooperates with...

Problems solved by technology

[0004] Although the increase of the separation spring can ensure that the plug can be quickly separated from the socket, it brings inconvenience to the insertion of the plug and the socket.

Specifically, the setting of the separation spring directly increases the insertion resistance between the plug and the socket, which in turn causes an increase in the connection torque of the connecting nut assembled on the plug housing, hindering the insertion between the plug and the socket. combine

For example, generally when the friction force of the contact piece is 60N, the elastic force of the separation spring should be designed to be 120N, so that the force to be overcome when the plug and the socket are mated is 180N, which is equivalent to the general bayonet connector. difficulty
