Abstract

An electric connector comprises an insulating body, a plurality of conductive terminals and an absorption cover, wherein the insulating body comprises a first side and a second side, two first hanging benches are arranged on the first side by intervals, and two second hanging benched are arranged on the second side by intervals, distance between the two first hanging benches is smaller than that of the two second hanging benches; and the conductive terminals are accommodated in the insulating body;the absorption cover is arranged above the insulating body, two first clamping hooks corresponding to the two first hanging benches are arranged on the absorption cover, two second clamping hooks corresponding to the two second hanging benches are also arranged on the absorption cover. When the absorption cover is correctly buckled on the insulating body, the first clamping hooks are clamped at the first benches and the second clamping hooks are clamped at the second hanging benches to fix the absorption cover onto the insulating body; and when the absorption cover is wrongly buckled on the insulating body, the first hanging benches interfere with the second clamping hooks so as to realize a fool proof effect.

Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, refers to a kind of electric connector that is used to connect a chip module especially.

[background technology]

The common a kind of electric connector that is used to connect a chip module of industry, it comprises an insulating body that is assembled with a plurality of conducting terminals and is positioned at one of described insulating body top draws lid.Wherein, described absorption lid has a relative first side and one the 3rd side, and a relative second side and a four side; Described first side and described the 3rd side have at least one trip respectively, corresponding described trip is provided with at least one groove on described insulating body, when described absorption lid is fastened on the described insulating body, described trip is fastened in described groove, moves relative to described insulating body in order to the described absorption lid of block; Described second side is provided with 2 first breach, corresponding described 2 first breach are provided with 2 first projections on described insulating body, described four side is provided with one second breach, corresponding described second breach is provided with one second projection on described insulating body, when correct installation of described absorption lid, each described first projection correspondence enters described first breach, and the described second projection correspondence enters described second breach; When wrong installation of described absorption lid, described first projection and described second projection are interfered the effect that can to a certain degree reach fool proof with described absorption lid respectively.

But, in the prior art, in order to realize that fixing described absorption lid to the structure of described insulating body function is to be positioned at described first side and the described trip of described the 3rd side and the described groove of the corresponding described trip setting of described insulating body, and what realize the fool proof function is described first projection that is positioned at corresponding described first breach setting with described insulating body of described first breach of described second side, and described second projection that is positioned at corresponding described second breach setting with described insulating body of described second breach of described four side.Hence one can see that, described electric connector realizes that the structure of fixed function lays respectively at the described absorption lid side different with described insulating body with the structure that realizes the fool proof function, it is the four sides that described electric connector must be employed described absorption lid and described insulating body respectively, therefore, described electric connector structure need increase the mould die sinking program of response when moulding, make procedure complicated, increased processing cost.

Therefore, be necessary described electric connector is improved, to overcome above-mentioned defective.

[utility model content]

Creation purpose of the present utility model is to provide a kind of electric connector that fixed function and fool proof function are realized in same structure.

In order to achieve the above object, the utility model buckle structure adopts following technical scheme:

A kind of electric connector, comprise an insulating body, it comprises a relative first side and a second side, described first side is interval with 2 first hanging platforms, described second side is interval with 2 second hanging platforms, and the wide cut between described 2 first hanging platforms is less than the wide cut between described 2 second hanging platforms; A plurality of conducting terminals are contained in the described insulating body; One draws lid, be positioned at the top of described insulating body, cover corresponding described 2 first hanging platforms in described absorption and be provided with 2 first trips, cover corresponding described 2 second hanging platforms in described absorption and be provided with 2 second trips, when described absorption lid is fastened on the described insulating body, described first trip is fastened in described first hanging platform, and described second trip is fastened in described second hanging platform.

Compared with prior art, when described absorption lid correctly is installed on the described insulating body, described first trip is fastened in described first hanging platform, described second trip is fastened in described second hanging platform, can play the effect that described absorption lid is fixed to described insulating body thus, again because described 2 first hanging platforms between wide cut less than the wide cut between described 2 second hanging platforms, be that distance between described 2 first hanging platforms and the distance between described 2 second hanging platforms do not wait, when wrong installation of described absorption lid, because distance does not wait, so described first hanging platform and described second trip, described second hanging platform and described first trip wherein an assembly credit union interfere, therefore, described absorption lid can not correctly be installed on the described insulating body, has played the effect of fool proof thus.In other words, the utility model is realized fixed function and fool proof function in same structure, simplified procedure and saved cost, is convenient to the extensive use of described electric connector.
