Problems solved by technology

[0004] Although the increase of the separation spring can ensure that the pull-off electrical connector can be quickly separated from the mating connector, it brings inconvenience to the insertion and mating of the mating connector
Specifically, the setting of the separation spring directly increases the mating resistance of the pull-off electrical connector and the mating connector, which in turn causes an increase in the connection torque of the connecting cap assembled on the housing, hindering the pull-off electrical connector. Mating between connector and mating connector
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 pull-off electrical connector is mated with the mating connector is 180N. Bayonet connectors are already quite difficult

Embodiment Construction

[0017] Embodiments of plug-in and labor-saving pull-off electrical connectors, such as Figure 1-2 As shown, the electrical connector has a front end as a plug-in end, and includes a housing 11 and a connecting cap that is rotatably assembled on the housing 11 .

[0018] The outer contour of the casing 11 is cylindrical, and an outer edge is provided on the outer peripheral surface between the two ends, and the outer edge forms a stop structure for blocking and matching with the connecting cap.

[0019] The connection cap includes a rotating sleeve 12 and an annular baffle 13 that is detachably and fixedly assembled on the rear end of the rotating sleeve 12. The rotating sleeve 12 is set on the housing 11, and the annular baffle 13 is detachably and fixedly connected with the rotating sleeve 12 through screws. The everted edge of the body 11 is located at the rear and forms a blocking wall for the connection cap. There is also a rolling body 14 between the annular baffle 13 a...

Abstract

The invention relates to the field of electrical connectors, and especially relates to a pull-off electrical connector labor-saving in plugging. The pull-off electrical connector labor-saving in plugging takes the front end as a plugging end, and comprises a housing and a connecting cap rotatably assembled on the housing. The connecting cap is in anti-play fit with the 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 housing through a rolling body. As the front side of the retaining wall of the connecting cap of the pull-off electrical connector labor-saving in plugging is in rolling fit with the 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 electrical connector. Background technique [0002] The pull-off electrical connector is a relatively common type of electrical connector. The electrical connector includes a housing, a contact piece assembled in the housing through an insulator, and a mandrel locking mechanism fixedly assembled in the housing. The core The shaft locking mechanism includes a shaft sleeve, a mandrel mounted in the shaft sleeve, a spring sleeved on the mandrel and a steel ball on the shaft sleeve. When mated with a suitable connector, the mandrel is locked The mechanism cooperates with the locking ring in the matching connector to lock the pull-off electrical connector and the matching connector together. When it needs to be electrically separated from the matching connector, it is only necessary to pull the mandrel to separate electrically. The shells betwe...
