[technical field]

The utility model relates to a kind of electric connector, the especially a kind of electric connector of chip module to the circuit board that electrically connect.

[background technology]

Electric connector is widely used on the personal computer.United States Patent (USP) the 7th, 001, disclosed a kind of existing electric connector for No. 197, it comprises insulating body that is provided with plurality of conductive terminals and the holding unit that insulating body is fixed to printed circuit board (PCB), described holding unit comprises iron plate, following iron plate and depression bar, wherein insulating body is that group is located at down in the iron plate, and last iron plate then is a side that is articulated in down iron plate rotationally, then is articulated with above-mentioned depression bar at the opposite side that descends iron plate.After chip module was positioned on the insulating body, last iron plate rotated and covers above chip module, re-use at last depression bar last iron plate clinching on following iron plate, electrically contact with conducting terminal in the insulating body to guarantee chip module.Yet this electric connector when using on the table the type computer, because the space is enough, without any problem, but when using on mobile computer, just cannot use the depression bar structure of rocker-type.

The TaiWan, China patent has disclosed another kind of improved electric connector for M328108 number, is different from above-mentioned electric connector, and it does not set iron plate and depression bar.This electric connector compresses the chip module that is contained in the insulating body by a pressing plate is set above insulating body.This pressing plate extends the installation foot of pressing close to printed circuit board (PCB) downwards near its four corners, be formed with an installing hole on each installation foot.With the cooperation of bolts and nuts, described pressing plate can be fixed on the printed circuit board (PCB) and push chip module downwards simultaneously, electrically contacts with conducting terminal to guarantee chip module.Yet, the downforce of uniform and stable can be provided in order to ensure pressing plate, have relatively high expectations for using this assembling procedure of bolt pressing plate installation foot, operation is more loaded down with trivial details, it is too tight that the bolt in any corner is locked, may guide the installation foot perk in other three corners, and can't make pressing plate reach the requirement of assembling.

So, be necessary above-mentioned electric connector is improved to solve the problems of the technologies described above.
