Description

Electric connector

[technical field]

The utility model refers to a kind of electric connector that is used to connect wafer module and circuit board especially about a kind of electric connector.

[background technology]

At present; be used for connecting the connector of wafer modules such as central processing unit and circuit board; particularly be used for the electric connector of testing wafer module; comprise insulating body substantially; be located at be used in the insulating body connecting wafer module conductive feet and circuit board conducting terminal and be used for driving wafer module and conducting terminal contact and the drive unit that separates; wherein a lot of class conducting terminals are provided with the stitch that can be inserted in the circuit board; and these stitch all stretch out outside the insulating body; store at connector; damage extremely easily in the transportation; for the stitch of these conducting terminals of better protection and do not hinder the use of connector, connector is provided with a stitch protective device in addition.

Disclosed a kind of protective device of conducting terminal stitch in No. the 5669780th, the United States Patent (USP) of on September 23rd, 1997 bulletin, its main body is a baffle, baffle be provided with can insert for stitch with the corresponding hole of stitch, this plate is provided with some trips towards the direction of insulating body, these trips can hold on the set boss of insulating body, trip can upwards be floated by extreme lower position, baffle was in extreme lower position before electric connector is inserted into the circuit board use, the conducting terminal stitch inserts in the hole of baffle and stretches out a very little part, can prevent the fracture injury of stitch; When electric connector is in running order, the baffle come-up, stitch is inserted in the circuit board, and baffle does not hinder the use of electric connector.But, this be hooked in electric connector use before easily because of moving big distance on the reasons such as external force and vibration, it is elongated to make the conducting terminal stitch stretch out the baffle part, still can make the conducting terminal stitch be subjected to a certain degree damage.

For better protection terminal stitch, disclosed another kind of terminal stitch protective device in No. 5078626, the United States Patent (USP) of on January 7th, 1992 bulletin, the protective device cardinal principle that discloses in this device and No. 5669780, the United States Patent (USP) is identical, difference is that this protective device is provided with two class trips, first kind trip is identical with above-mentioned trip, also cooperate with the insulating body convex platform, only this first kind trip can not prevent the baffle come-up; The second class trip is provided with two chamfering inclined-planes, also be provided with the protuberance with two chamfering inclined-planes on the corresponding insulating body, when trip was in lower position, chamfering inclined-plane propped up the following chamfering inclined-plane of protuberance on it, can prevent the baffle come-up, first kind trip can prevent that baffle from gliding simultaneously; After the baffle come-up, the following chamfering inclined-plane of the second class trip cooperates with the last chamfering inclined-plane of protuberance can prevent that baffle from gliding.So, this terminal stitch protective device can better protection terminal stitch in electric connector transportation storing process.

Above-mentioned first kind of terminal stitch protective device can not play a very good protection to stitch; the second class terminal stitch protective device; though can play a protective role; but the different trip of two classes need be set; and two class projections to be set also on the electric connector insulating body; make more complicated; therefore and the stitch protective device can only be positioned at a position away from insulating body, and it is easier and can play the electric connector of better protective effect to overcome above-mentioned disappearance to the terminal stitch to be necessary to propose a kind of manufacturing.

[utility model content]

The purpose of this utility model is to provide a kind of electric connector that can better protection terminal stitch.

Another purpose of the utility model is to provide a kind of manufacturing simple cost-effective electric connector.

The utility model is about a kind of electric connector that connects wafer module and circuit board; it comprises insulating body; be contained in the conducting terminal in the insulating body; can open and make position between the driving body that moves and be assembled on the insulating body can be in away from insulating body and near the protective device that moves between the insulating body; wherein conducting terminal is provided with the needle-like terminal supportor; protective device is provided with flat board; this flat board is provided with the through hole that can supply conducting terminal needle-like terminal supportor to pass; be provided with the plate that overhangs towards insulating body one side on the flat board; the plate that overhangs is provided with trip and projection; trip is positioned near overhanging the plate terminal position; insulating body is provided with the boss that cooperates with trip and projection; when trip snaps on the boss; flat board is in the position away from insulating body, leaves a space between projection and the boss.

Compared with prior art; the utlity model has following advantage: this electric connector is because trip and the projection that is provided with on the plate that overhangs of protective device; boss is set on the insulating body; and boss is between trip and boss the time; and can leave a fixed gap between trip or the boss, the flat board of protective device can be limited between two diverse locations away from insulating body, so that conducting terminal needle-like terminal supportor is played a protective role; only be provided with a class projection, escapable cost on the insulating body simultaneously.
