Actuator 4 rotatable being installed on the insulating body 2, the rotation section 41 that it has a lengthwise shape board 40, stretched out by these board 40 two ends and bury molding mode with edge and be assembled in metal reinforced sheet 42 on the board 40, this metal reinforced sheet 42 is the intensity that is used to increase board 40, it comprise have edge be embedded in the board 40 lengthwise shape base portion 420 and by these base portion 420 two ends perpendicular to base portion 420 kinks 421 of bending downwards, be respectively equipped with the projection 422 of polygon boss columnar structure in the centre position of two kinks 421.Board 40 is provided with and is used for flexible PCB (not shown) is crimped to the opposite 402 that crimping face 400 reaches and this crimping face 400 is oppositely arranged that flexible PCB and electric connector 1 formation are electrically conducted, and crimping face 400 is provided with the protuberance 401 of the crimping face of protruding from 400, and rotation section 41 is contained in the location notch 211 of card arm 21, and can be around insulating body 2 rotations.

Metal shell 5 is coated on the upper surface 201 of matrix 20 of insulating body 2, matrix 20 and card arm 21 positions corresponding to insulating body 2 on this metal shell 5 are respectively equipped with combination section 50 and strengthen arm 51, and in being respectively equipped with " T " type groove 500 and ground strip 501 corresponding to " T " type projection 202 on the matrix 20 and groove 205 positions on the combination section 50, this ground strip 501 is used for ground connection such as static on the metal shell 5 and noises.Be provided with and be bent into inverted U-shaped containing portion 510 with two parallel side walls and the connecting portion 513 that connects this containing portion 510 and combination section 50 and strengthen arm 51, be formed with a cavity 511 in the middle of this containing portion 510, in order to the arm 212 of accommodating card arm 21, on the relative two side of two containing portions 510 in being provided with a recess 512 near bending corner location place, and after keeping at a certain distance away with this recess 512, offer a draw-in groove 5120 that is through to this sidewall end along this madial wall, above-mentioned draw-in groove 5120 roughly is in same linear position with recess 512 on the longitudinal extension direction of madial wall.Connecting portion 513 is an elongate sheet metal, it is provided with vertical card cramp 514 near 50 positions, combination section, this buckling piece 514 bent back hooks are on location division 210, and connecting portion 513 then is connected on the lateral wall of card arm 21 location divisions 210 intensity with increase location division 210.

Please in conjunction with consulting Fig. 3 and Fig. 4, when this electric connector 1 in when assembling, earlier conducting terminal 3 is inserted in the insulating body 2 along terminal groove 200 directions, then " T " type projection 202 of " T " type groove 500 on the combination section 50 of metal shell 5 on the matrix 20 of insulating body 2 is combined in, ground strip 501 on the combination section 50 is fastened mutually with groove 205 on the matrix 20, and the arm 212 of card arm 21 is inserted in 510 liang of formed cavitys 511 of flat shape sidewall of containing portion, bend the sidewall of containing portion 510 inboards then, arm 212 is coated by containing portion 510 fully, and bend buckling piece 514 simultaneously, make its hook on the location division 210 on the insulating body 2 card arms 21, and connecting portion 513 will be connected on the sidewall of location division 210, at last the rotation section 41 of actuator 4 is snapped in the location notch 211 on the card arm 21 of insulating body 2, be snapped in the recess 512 in the containing portion 510 and be located at projection 422 on the kink 421 of metal reinforced sheet 42, this promptly finishes the assembling of this electric connector 1, and this moment, actuator 4 can rotate around the location notch on the insulating body 2 211.

When electric connector 1 and flexible PCB (not shown) are combined, earlier actuator 4 being rotated makes it keep vertically perpendicular to insulating body 2 directions, this moment is with in the opening (not shown) of flexible PCB with the leading section of zero insertion force insertion insulating body 2, conducting strip on the flexible PCB does not also contact with the contact site of conducting terminal 3 fully at this moment, after flexible PCB inserts fully, rotating drive part 4 also makes it get back to horizontal level from vertical position, protuberance 401 on the board 40 of actuator 4 will push flexible PCB and flexible PCB is crimped on the conducting terminal 3 tightly at this moment, and the projection 422 on metal reinforced sheet 42 kinks 421 is posted by in the recess 512, then, further be rotated down actuator 4, cause kink 421 inwardly to make a concession distortion, thereby making projection 422 break away from recesses 512 continues to move downward and enters draw-in groove 5120, after removing external force, actuator 4 has a trend that rotates up, thereby make projection 422 be resisted against the inner edge of draw-in groove 512, projection 422 please refer to Fig. 5 with the situation that cooperates of draw-in groove 514, this moment flexible PCB conducting strip will because of the contact site fluid-tight engagement of the squeezing action of actuator 4 and conducting terminal 3 together, thereby form the electric connection of 1 of flexible PCB and electric connector.

By the above-mentioned metal reinforced sheet 42 that is embedded in the actuator 4, can increase the intensity of actuator 4, prevent that actuator 4 from rupturing because of insufficient strength in pushing the flexible PCB process, in addition, each buckle assembly, be that projection 422 on the kink 421 of metal reinforced sheet 42 matches with draw-in groove 5120 on the metal shell 5, can prevent to come off after flexible PCB from installing, increase the stability that electrically connects.

In another embodiment, each buckle module position exchanges, promptly on the kink of metal reinforced sheet, offer draw-in groove, and on the arm of metal shell even insulating body, add projection, can realize increasing actuator intensity and the stable effect that fixes equally, its operation principle and to reach effect identical with first execution mode does not repeat them here.
