Description
[technical field]
The utility model relates to a kind of electric connector, especially a kind of improvement of testing the electric connector terminal baffle.
[background technology]
In electronic industrial products, before dispatching from the factory, need a process chip to be installed on the different processor sockets at different test events through various tests.For example processor chips may need the detection through test, different performance such as aging.
Existing processor chips are carried out the electric connector for socket of burn-in test, one group of snap close piece that it generally includes a pedestal, is assembled in the upper cover body on the described pedestal and is driven by described upper cover body, multi-conducting terminals is contained in the described pedestal.Described upper cover body can move up and down by described relatively pedestal, and when when depressing described upper cover body, described upper cover body is pushed described snap close piece, and described snap close piece is in open mode, and can be loaded on described electric connector this moment with described process chip.
The described electric connector for socket of this burn-in test need be installed on the circuit board usually; because described socket electrical connection device has a lot of described terminals usually; and described tail portion of terminal is longer; need in the corresponding perforation of inserting on the described circuit board of numerous described terminals; for guaranteeing that numerous described terminals can insert in the described perforation of described circuit board correspondence simultaneously exactly; the described terminal of avoiding inserts described perforation and the described terminal that has does not cause damage to inserting described terminal when not inserting described perforation, can one terminal protecting plate be set in the bottom of the described pedestal of described electric connector for socket usually.Numerous described terminals insert in the terminal channel of described terminal protecting plate earlier; and then described terminal is inserted in the described perforation of described circuit board; because the protection of the location of described terminal protecting plate, the described terminal that then can avoid having than long-tail portion produces dislocation and damages described terminal when inserting described circuit board.
Existing electric connector for socket; its described base bottom surface can be provided with two reference columns along diagonal usually; the diagonal that the described reference column of the bottom surface of described terminal protecting plate and described pedestal intersects also is provided with two reference columns; and be formed with two perforation in another diagonal of described terminal protecting plate; two described reference columns on the described base bottom surface pass two described reference columns on the described terminal protecting plate, and the described perforation of inserting again on the described circuit board further is fixed in described electric connector on the described circuit board.
Though described electric connector is provided with described perforation on described terminal protecting plate; pass for the described reference column on the described pedestal; guaranteed to insert on the described circuit board at the described reference column of described pedestal; described pedestal can not produce with respect to described terminal protecting plate and rock, but still has weak point:
1. because described terminal protecting plate is roughly rectangular; only the diagonal direction in described terminal protecting plate bottom surface is provided with two contour described reference columns respectively; based on 2 principles of still can not determine a plane; when described terminal protecting plate top surface is under pressure when described circuit board advances; stressed situation pockety can appear in described terminal protecting plate top surface; if stressed other position, position that does not have described reference column to support on the described terminal protecting plate greater than described terminal; described terminal protecting plate will produce in stressed excessive place; so that described terminal is lateral stressed, cause described terminal bending.
2. because the described reference column on the described pedestal is the through hole that passes earlier on the described terminal protecting plate; insert again on the set described circuit board of described circuit board; and the diameter of the described through hole on the diameter of the described reference column on the described pedestal and the described terminal protecting plate is more or less the same; described reference column on described pedestal is through in the process of described through hole; inboard with described through hole produces friction easily; even stop that the described reference column on the described pedestal passes, cause described reference column on the described pedestal can not be assembled in situation on the described circuit board with this.
Therefore, be necessary to design a kind of new electric connector, to overcome the problems referred to above.
[utility model content]
At the variety of problems that background technology faced, the purpose of this utility model is to provide a kind of processing procedure simple and easy, compact conformation, again can baffle and insulating body unbalance stress and make the electric connector of dandle.
For reaching above technical purpose, the utility model adopts following technical scheme:
A kind of electric connector, it comprises a pedestal, and its bottom surface is provided with at least three first reference columns, is that the diagonal angle encloses formation one accommodation space with each described first reference column, and described first reference column is provided with one towards described accommodation space and is subjected to stopper; Most terminals are revealed in described insulating body bottom surface; One baffle; be positioned at described accommodation space; and connect described terminal; in the bottom surface of described baffle and the place, diagonal angle that is positioned at described accommodation space all protrude out at least one second reference column; be provided with a stopper in described second reference column with respect to described stopper one side that is subjected to, the described stopper that is subjected to stops that described stopper is towards moving away from described accommodation space.
Compare with prior art; the utility model electric connector is provided with described second reference column by each edge at described terminal protecting plate lower surface; when the described second reference column group is gone into described circuit board; four described second reference columns abut against the inboard in described hole always; can guarantee that described second location firmly can enter the hole on the described circuit board simultaneously, effectively avoided since described terminal protecting plate owing to unbalance stress makes described terminal protecting plate dandle.
Moreover; when described second reference column enters described hole and described terminal protecting plate and is still in the upper surface of described circuit board; the described stopper that is subjected on each described first reference column can continue to enter described hole along the described stopper of correspondence; each described constraint that is subjected to stopper can be subjected to corresponding described stopper in this course; and avoid whole described pedestal dandle, and from reaching the effect of the described terminal of protection.Above technology implementation operation is simple, easy operating.
