The another kind of electric connector relevant with the utility model, this electric connector and electric connector structure shown in Figure 1 are basic identical, and different is that crimp type terminal and metal shell are the single type structure.

Because the holding wire of above-mentioned electric connector carrying is more and the frequency height of signal, this also requires the lead division 23 ' of flexible PCB 2 ' to have enough width.Yet, widen flexible PCB 2 ', certainly will will increase the size of electric connector, obviously, in the electric connector not tolerable that the defective of this expansion size becomes under the background of miniaturization day by day.

Given this, be necessary to provide a kind of electric connector to address the above problem in fact.

[utility model content]

It is little and electrically connect reliable electric connector that the technical problems to be solved in the utility model provides a kind of volume.

The utility model solves the problems of the technologies described above like this: a kind of electric connector comprises metal shell and some crimp type terminals, described metal shell and crimp type terminal are the single type structure, metal shell comprises diapire, from the upwardly extending left and right sidewall in the relative both sides of diapire, the antetheca and the rear wall relative that extend toward each other from the identical side of left and right sidewall respectively with this antetheca, described sidewall is formed with receiving space, antetheca comprises opening, the elastic arm that extends and is positioned at elastic arm feed opening on every side that described opening and described feed opening communicate in receiving space.

Compared with prior art, the utility model electric connector opening and described feed opening communicate and can effectively reduce the volume of electric connector, guarantee to electrically connect reliably.

[embodiment]

Below, will describe in further detail the utility model in conjunction with the accompanying drawings.

The utility model is that a kind of flexible PCB 2 that utilizes is connected to the electric connector (not shown) of circuit board (not shown) with camera module 3, and it comprises metal shell 4 and some crimp type terminals 401.

Please join shown in Figure 3; metal shell 4 is to be formed by metallic plate punching press bending; it has the receiving space 400 that holds camera module 3; this receiving space 400 is by flat base wall 40; left side from diapire 40; right edge (not indicating) the identical left side of upwardly extending a pair of structure; right side wall 41; 42; from diapire 40 back side edge (not indicating) upwardly extending rear wall 43 and respectively from a left side; the a pair of antetheca 44 that the front side edge of right side wall 42 is extended toward each other centers on formation; and above-mentioned diapire 40 and sidewall 41; 42; 43; 44 electrically contacts each other can protect camera module 3 not to be subjected to outside electromagnetic interference so preferably.Wherein said diapire 40 is provided with the some crimp type terminals 401 that extend in receiving space 400; Left and
