Description

Electric connector

[technical field]

The relevant a kind of electric connector of the utility model refers in particular to a kind of electric connector with a pull bar and a pair of clasp.

[background technology]

United States Patent (USP) the 5th, 564 has disclosed a kind of electric connector No. 939, and it has a pair of clasp 22 and 22A, and this is retained on the both sides of electrical connector body 21 respectively to clasp.Operating portion 23 has on a pair of cam 23-4 that is positioned at clasp 22,22A bend 22-4.When pulling back the operating portion of pull bar, cam 23-4 applies an outside active force makes U-shaped hook portion 22-1 break away from butt connector in bend 22-4.Because of operating portion 23 and clasp 22,22A are installed on body 21 outsides, when being applied thereto, external force is easy to by corrupted.When two or more connectors are settled side by side, just need relatively large space between two connectors, be unfavorable for saving the space of the electrical system that this kind connector is installed.In addition, after acting on pulling force on the operating portion 23 and removing, clasp 22,22A will produce elastic force and order about operating portion 23 and return to original position.But elastic force is too little and can not make operating portion 23 playback.In order to overcome above-mentioned defective, but be necessary to provide a kind of electric connector of pull bar automatic homing.

[summary of the invention]

But main purpose of the present utility model is to provide a kind of electric connector of its pull bar automatic homing.

For achieving the above object, the utility model adopts following technical scheme: the utility model electric connector includes pedestal, metal clips, connector component, a pair of clasp, pull bar and lid; The front end of pedestal has an interface frame, mating frame, metal clips is assembled on the pedestal, connector component is assembled on the pedestal and one extends partially in the interface frame, mating frame, but clasp is assembled in the relative both sides and the lateral deflection of pedestal, and pull bar is assembled on the pedestal, it has pair of catches release portion, when pulling back pull bar, snap close release portion promotes the clasp lateral deflection, and shell fragment produces strain, after pull bar discharged, shell fragment applies elastic force to pull bar made pull bar and clasp get back to original position.

Compared to prior art, but the utility model makes pull bar and clasp automatic homing by elastic device, and is easy to operate, the packaging efficiency height, thus reduce manufacturing cost.
