Embodiment
Please refer to shown in Fig. 1 to Fig. 5, that show the concrete structure of the utility model electric connector, it includes insulating body 10, the conducting terminal 20 be contained in insulating body 10, relative to insulating body 10 rotate turn pressing plate 30 and metalwork 40.Wherein:
Described insulating body 10 is roughly in rectangular-shaped, front end is provided with spacious empty receiving space 11, this receiving space 11 includes two side and diapire, respectively ear 12 is provided with to receiving space projection above the front end of described two side, a square socket is defined in the insertion that can be for flexible printed circuit board 50 of this ear 12, front end face again in two side is provided with slot 13, and this slot 13 is for inserting for metalwork 40.The both sides of described diapire front end are respectively provided with a stopper section 14, and this stopper section 14 is blocked in the breach 51 on flexible printed circuit board both sides, to prevent exiting of flexible printed circuit board 50.The rear end of described insulating body 10 is provided with some terminal grooves 15, and this terminal groove 15 is through in receiving space 11.
Described conducting terminal 20 inserts from the terminal groove 15 of insulating body 10 and is positioned terminal groove 15, and the contact jaw of its front end stretches in receiving space 11, carries out Signal transmissions to contact with flexible printed circuit board 50.
Describedly turn the rectangular shape of pressing plate 30 equally in lengthwise, these both sides turning pressing plate 30 are provided with the rotating shaft 31 be supported on receiving space two side, centre is provided with the some spacer holes 32 be buckled on conducting terminal, this turns pressing plate 30 and freely can rotate relative to insulating body 10 in receiving space 11 and realize opening and closing, and these both sides turning pressing plate 30 are also provided with the stuck point 33 for turning pressing plate 30 snap close.
Described metalwork 40 is stamped to form by sheet metal, and it includes fixed part 41, grounding leg 42 and pressure section 43.Described fixed part 41 is vertical shape, is vertically plugged in the slot of insulating body; Described grounding leg 42 extends from the lower ora terminalis of fixed part 41 side, welds on circuit boards and provides ground connection; Described pressure section 43 extends from the upper edge of fixed part 41 to opposite side, this pressure section 43 is mutually vertical with fixed part 41, thus make pressure section 43 extend into the top of receiving space 11, and the diapire certain altitude of distance insulating body 10, this is highly greater than the thickness of flexible printed circuit board 50, and can be flexible printed circuit board 50 provides zero insertion force to insert.Described pressure section 43 extends to the openend direction of insulating body and is provided with elastic arm 431, this elastic arm 431 is undulate slightly, a contact site contacted with screen 432 is provided with in the middle of it, this contact site continues to extend forward to be provided with a forced section 433, and this forced section 433 can drive contact site 432 to move downward by external force situation.
