Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, refers to a kind of electric connector of zero insertion force especially.

[background technology]

Existing zero inserting force electric connector generally has pedestal, be located in the pedestal conducting terminal, group are located at lid and drive unit on the pedestal.Wherein top surface offers jack usually, and with the pin of guiding central processing unit chip, when the central processing unit chip was inserted on the electric connector, its pin contacted with corresponding conducting terminal, electrically conducts to realize it.This electric connector is on being mounted to circuit board the time, be to draw to circuit board by vacuum slot to fix by welding again, therefore need on this electric connector, to install one in addition usually and draw lid, form by the extended buckling parts in body two ends and generally draw to cover to reach by flat body usually, match with this electric connector by buckling parts, make to draw to cover firmly to be connected on the electric connector.But this absorption lid when mounted, draws lid and can not get locating exactly, can cause inconvenience, inefficiency are installed.

Therefore, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of electric connector, and it can make draws the easy for installation, accurate of lid, and can increase work efficiency greatly.

In order to reach above-mentioned creation purpose, the utility model electric connector comprises body, conducting terminal and is positioned at absorption lid on the body that this absorptions lid and body are respectively equipped with at least one reference column that cooperatively interacts and location hole.

Compared with prior art, the utility model electric connector, it can make draws the easy for installation, accurate of lid, and can increase work efficiency greatly.

[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model electric connector is described further.

As shown in Figures 1 to 4, the utility model electric connector, can be installed on the circuit board (not icon), be used for accepting butt joint electronic building brick (present embodiment be central processing unit (CPU) chip) (not icon), it comprises body, plurality of conductive terminals (not shown) and the absorption that is positioned on the body covers 4.

Body comprises the lid 2 of pedestal 1, pedestal slip relatively and the rocking bar 3 that drives lid and pedestal slide relative.Wherein rocking bar 3 is by an axle center part (not shown), is approximately perpendicular to the operating portion 31 of axle center part and forms (certainly, also can be other drive units such as cam) from axle center part to projecting inward drive division (not icon).By the rotation of rocking bar 3, can order about lid 2 relative pedestals 1 and between opening and closure state, change.

Pedestal 1 is made up of the insulating material that slightly is square, and which is provided with some terminal accommodation holes (not shown) of accommodating conducting terminal, and conducting terminal is arranged in this terminal accommodation holes.

Lid 2 is connected on the pedestal 1 slidably, form by the insulating material that slightly is square, have the continuing surface 20 that can accept the central processing unit chip, the both sides of the edge of this continuing surface 20 are provided with the framework 200 that protrudes out the continuing surface certain distance, respectively are arranged with two location holes 201 in the both sides of framework 200.And on continuing surface 20, be provided with and the corresponding some through holes 202 of the terminal accommodation holes of pedestal, be used for pegging graft for the pin of the central processing unit chip thereon of planting.

This absorption lid 4 comprises flat plastic body 40 and by the buckling parts 41 of plastic body both sides extension to match with body, respectively is provided with two in the position near buckling parts 41 and is symmetrically arranged reference column 42 that this reference column 42 is round table-like.It can match with above-mentioned location hole 201, makes to install to draw to cover can be located exactly in 4 o'clock, and is easy for installation, and has improved operating efficiency.

Certainly, in the above-described embodiments, to shown in Figure 8, the through hole 202 that also can be two side positions setting on the lid 2 is as location hole as Fig. 5, and described reference column 42 matches with it, also can reach the effect of accurate location.
