The utility model relates to an electrical connector, which is used for electrically connecting a cable or a flexible circuit board. The cable or the flexible circuit board is provided with a conductive body. The electric connector comprises a shell, an insulation body and an elastic body, wherein the insulation body is provided with a main body which is provided with a first surface and a second surface which are opposite, and the main body is provided with a through hole which penetrates the first surface and the second surface. The conductive body is fixed on the second surface of the main body, and at least one part of the conductive body is positioned at the through hole position. The shell is movably connected to the upper part of the insulation body. The elastic body is fixed on the shell and corresponds to the through hole. When a cover body is in a close state, the elastic body can penetrate through the through hole and press the conductive body, which causes the conductive body to protrude form the second surface. The utility model can direct connect the cable or the flexible circuit board, and the utility model has the advantage of convenient connection, and can ensure good electrical connection with the cable or the flexible circuit board.

Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, especially refers to a kind of electric connector that is used for connection cable or flexible PCB to circuit board.

[background technology]

In various portable electron devices, situation about two circuit boards need be connected usually appears, especially a flexible circuit board is connected with a rigid circuit board, shown in No. the 6045396th, United States Patent (USP), the board to board connector of the prior art comprises a pair of rigidity clamping plate and a pair of screw that is located at the clamping plate two ends, the termination contact portion of clamping two circuit boards makes them reach electric connection to the rigidity clamping plate by the fastening force of screw.Yet the rigidity clamping plate that this board to board connector adopted provide clamping power by the fastening of the screw at two ends, and are inconvenient when the installation and removal flexible circuit board, and the existence of screw, and the height of this board to board connector can't be reduced.

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

[summary of the invention]

It is a kind of simple in structure that the purpose of this utility model is to provide, and assembling is easy to electric connector.

For achieving the above object, the utility model electric connector, be used to electrically connect cable or flexible PCB, cable or flexible PCB are provided with electric conductor, it is characterized in that: this electric connector comprises housing, insulating body and elastomer, insulating body is provided with the main body with opposite first and second surface, and main body is provided with the through hole that runs through first surface and second surface, electric conductor is fixed in the main body second surface and is positioned at lead to the hole site to small part, housing is movably connected on the insulating body, elastomer is fixed on the housing, and corresponding with through hole, when lid is closure state, elastomer can pass through hole and compress electric conductor, makes electric conductor protrude in second surface.

Compared with prior art, but the utility model electric connector tieline cable or flexible PCB are easy to connect, and electrically connect preferably between energy assurance and cable or the flexible PCB.

[embodiment]

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

See also Fig. 1 to Fig. 3, the utility model electric connector 1 is used to electrically connect cable 6 (also flexible PCB) and circuit board 4, comprises insulating body 2, elastomer 3 and housing 5, and cable 6 is provided with electric conductor 60.

Wherein, insulating body 2 roughly is shape, it is provided with the main body 20 with relative first surface 201 and second surface 202, second surface 202 is used for matching with circuit board 4, main body 20 is provided with the through hole 203 that runs through first surface 201 and second surface 202, in addition, insulating body 2 is formed with receiving space 22, to accommodate circuit board 4.

Housing 5 is movably connected on the insulating body 2, comprise tabular main part 50, autonomous both sides, body 50 end extension downwards are provided with ear 51, and ear 51 is provided with hole (indicating among the figure), other end extension downwards is provided with holding part 52 relatively, can be buckled in the end of insulating body 2 correspondences; Corresponding with the hole of

ear

51,2 liang of upper lateral parts of insulating body stretch out and are provided with projection 25, and projection 25 can match with the hole of ear 51, and housing 5 and insulating body 2 are articulated.

Cable 6 is fixed in the insulating body 2, comprise electric conductor 60, at least a portion electric conductor 60 is positioned at through hole 203 positions of insulating body 2, elastomer 3 is fixed on the housing, and corresponding with through hole 203 property, when housing 5 was closure state, elastomer 3 can pass through hole 203 and compress electric conductor, make electric conductor 60 protrude in second surface 202, form contact site 600.

When connecting circuit plate 4, circuit board 4 is inserted in the receiving space 22, closure shell 5 again, and at this moment, the contact site 600 of cable 6 and the conduction region (not drawing among the figure) on the circuit board 4 contact, and make that being connected of contact site 600 and circuit board 4 is more reliable.

See also Fig. 4 to Fig. 6, this is second embodiment of the utility model electric connector.Be with the difference of first kind of embodiment: the upper and lower surface of circuit board 4 all is provided with conduction region (not drawing among the figure), insulating body 2 is provided with two main bodys: the one 20 and second main body 21, two agent structures are identical, and form a receiving space 22 between main body, to accommodate circuit board 4.Second main body 21 of its insulating body 2 is provided with through hole 205, second main body, the 21 outer same housings 7 that are provided with, housing 7 is provided with elastomer 3 ', housing 7 comprises tabular main part 70, autonomous both sides, body 70 end extend upward and are provided with ear 71, ear 71 is provided with hole (indicating among the figure), and other end extension downwards is provided with holding part 72 relatively, can be buckled in the end of insulating body 2 correspondences; Corresponding with the hole of
