[embodiment]

Please refer to Fig. 1 to shown in Figure 3, the utility model electric connector 100 is used to connect flexible PCB 40 (as shown in Figure 5), mainly includes insulating body 10, is contained in the conducting terminal 30 in the insulating body 10 and is installed on metal shell 20 on the insulating body 10.

Described insulating body 10 is provided with the receiving space (not label) of accommodating flexible PCB 40, and this insulating body 10 comprises two terminal holding parts that be arranged in parallel 11,13 and is shaped in the installation side arm 12 that both sides connect two terminal holding parts 11,13.Described installation side arm 12 rear portions are provided with fixing slot part 121, and relative front-end edge is provided with draw-in groove 122, and installation side arm 12 front-end edge inboards offer guidance part 123 and are used to guide flexible PCB 40 installation of (as shown in Figure 5).

Described conducting terminal 30 be divided into two

row

30a, 30b be respectively two row be arranged on the insulating body 10, and subtend is shaped in two terminal holding parts 11,13 respectively, and each conducting terminal 30 includes and insulating body 10 integrated holding parts (not shown), the weld part 33 that extends to form respectively from the holding parts two ends and protrude in insulating body 10 receiving spaces and the contact site 34 between two terminal holding parts 121.Two

row conducting terminal

30a, 30b plant from the fore-and-aft direction of the body 10 that insulate respectively to form relatively, and the contact site 34 of two

row conducting terminal

30a, 30b is provided with between two terminal holding parts 11,13 at interval.

Described metal shell 20 comprises plate-like body portion 21 and the sidepiece 22 that extends to form from 21 liang of lateral bucklings of plate-like body portion, described sidepiece 22 rear ends are extended with correspondence and are contained in axial region 221 in the insulating body 10 fixing slot parts 121, and metal shell 20 can pivot on insulating body 10 around this axial region 221; Corresponding insulating body 10 draw-in grooves of sidepiece 22 front ends 122 places are provided with trip 222, this trip 222 and draw-in groove 122 sealed with fixing metal housing 20 on insulating body 10, described trip 222 and axial region 221 are located at metal shell 20 sidepieces 22 rear and front ends respectively.Corresponding conducting terminal 30 contact sites 34 places have through hole 24 in the plate-like body portion 21 of metal shell 20, so, this through hole 24 is reserved enough spaces for conducting terminal 30 contact sites 34, thereby when flexible PCB 40 was not packed electric connector 100 into, the contact site 34 of conducting terminal 30 can not come in contact with metal shell 20.Plate-like body portion 21 through holes, 24 front ends close on installation side arm 12 draw-in grooves 122 places and are concaved with the pressure section 23 that is used for fixing flexible PCB 40.Described through hole 24 and pressure section 23 are located in the plate-like body portion 21 of metal shell 20.

See also shown in Figure 4, be unkitted fashionablely at flexible PCB 40, contact site 34 elasticity of conducting terminal 30 upwarp to metal shell 20 positions, because of the existence of through hole 24, contact site 34 can not touch metal shell 20, guarantees the phenomenon that can not be short-circuited between the conducting terminal 30.

See also shown in Figure 5, when flexible PCB 40 is packed electric connector 100 into, metal shell 20 pivots downwards and pushes flexible PCB 40, and then flexible PCB 40 is electrically contacted with conducting terminal 30 contact sites 34, the pressure section 23 of described metal shell 20 is directed downwards towards conducting terminal 30 and compresses flexible PCB 40, make flexible PCB 40 flexural deformations, thereby changed the force direction that is subjected to that external force is drawn flexible PCB 40, make flexible PCB 40 not be subject to external force and pull and come off.

The utility model electric connector 100 is by being provided with through hole 24 to guarantee the stable electrical switching performance of conducting terminal 30 contact sites 34 on the metal shell 20, the direction that pressure section 23 changes flexible PCB 40 external pull is set on the metal shell 20, further fixing flexible PCB 40 makes its difficult drop-off.
