Embodiment

For reaching above-mentioned purpose and effect, technological means that the utility model adopted and structure thereof, drawing now illustrates in detail that with regard to preferred embodiment of the present utility model its feature and function are as follows, conveniently understands.

Please consult Fig. 1, Fig. 2, Fig. 3, shown in Figure 4 simultaneously, be three-dimensional exploded view and the combination stereogram after stereogram, the first terminal and the assembling of second terminal for three-dimensional exploded view of the present utility model, insulating body, find out that by knowing among the figure electric connector of the present utility model is made up of an insulating body 1, plural the first terminal 2, plural second terminal 3 and a flip 4.

Insulating body 1 is to be a cuboid, it has an accommodation space 10 and the plural caulking groove 11 that is set up in parallel, this caulking groove 11 is the rears that are communicated to insulating body 1, and the bottom surface of the cell wall that this caulking groove 11 and caulking groove are 11 forms groove 12, and these accommodation space 10 two side walls and 11 of caulking grooves are provided with slot 13.

The first terminal 2 is to be made by metal material, each the first terminal 2 is to have upper arm 21 and the underarm 22 that almost parallel extends, the free end of this upper arm 21 is to form articulated section 211, the front bottom end of this underarm 22 is convexly equipped with a weld part 221, is elastic extension one portion 222 that is flexibly connected upwards towards the rear in underarm 22 than the front end place, and underarm 22 rear ends are to have protruded out positioning rib 223.

Second terminal 3 is to be made by metal material, each second terminal 3 has upper arm 31 and the underarm 32 that almost parallel extends, the front end of this upper arm 31 extends to form pressing down section 311 slightly downwards, and pressing down section 311 has a plurality of salient points 312, and the front end of underarm 32 forms contact site 321, have a plurality of salient points 322 on this contact site 321, and be provided with fixed part 33 in the rear extension of upper arm 31 and underarm 32, the below of this fixed part 33 is to form welding ends 331.

Flip 4 is made by the plastic material of insulation, and its place ahead is the flat pressing plate of a formation portion 41, and the rear of this pressing plate portion 41 is provided with plural axis part 42, and this axis part 42 is to be provided with corresponding to the articulated section 211 of the first terminal 2.

By the structure of above-mentioned each assembly when the assembling, be that plural the first terminal 2 and plural second terminal 3 are planted in the caulking groove 11 by the place ahead of insulating body 1 and rear respectively, making the first terminal 2 second terminals 3 is to be arranged at intervals in the caulking groove 11, this the first terminal 2 is to utilize positioning rib 223 to be embedded in the caulking groove 11, and the weld part 221 of the first terminal 2 is to be resisted against caulking groove 11 front ends and to protrude from insulating body 1 the place ahead slightly, the front end of the fixed part 33 of this second terminal 3 is to be embedded in the caulking groove 11, the welding ends 331 of the rear end of fixed part 33 and fixed part 33 belows then is resisted against caulking groove 11 rear ends and protrudes from insulating body 1 rear, so promptly finishes the assembling of the plural the first terminal 2 and second terminal 3; 13 of the slots of these insulating body 1 both sides can further plug a pair of spacer 5 (as shown in Figure 3), plural axis part 42 with flip 4 is hubbed at respectively on the articulated section 211 of the first terminal 2 at last, flip 4 can be open on insulating body 1 and cover rotation, and then finish of the present utility model group of structure (as shown in Figure 4).

See also Fig. 5 and shown in Figure 6, be to insert the generalized section of the stressed situation of back the first terminal and the generalized section that flexible flat cable inserts the stressed situation of back second terminal for the utility model flexible flat cable, as shown in the figure, when flexible flat cable 6 inserts, these flexible flat cable 6 front ends can touch the contact site 321 of second terminal 3 earlier, and then touch the portion that is flexibly connected 222 of the first terminal 2, this flexible flat cable 6 will produce a strength that presses down to the portion of being flexibly connected 222, then flexible flat cable 6 continues the pressing down section 311 that inside insertion can touch second terminal 3 again, and pressing down section 311 is produced the upwards strength of jack-up, after conflicting groove 12, flexible flat cable 6 front ends then locate; At this moment, portion 222 and pressing down section 311 produces and presses down and the strength of jack-up because 6 pairs of flexible flat cables are flexibly connected, to make portion of being flexibly connected 222 and pressing down section 311 produce reaction force and the upper arm 21 that is held on the first terminal 2 and second terminal 3 that flexible flat cable 6 front ends are firm, 31 and underarm 22, between 32, and effectively avoid flexible flat cable 6 to get loose, and the supporting of pressing plate portion 41 that cooperates flip 4 again, military order flexible flat cable 6 real firm location, make flexible flat cable 6 form stable electric connection, and then make transmission more smooth and easy stable with the portion that is flexibly connected 222 of the first terminal 2 and the contact site 321 of second terminal 3.

Moreover, the setting of the groove 12 in the insulating body 1, except avoiding the excessive insertion of flexible flat cable 6, and after can making flexible flat cable 6 location, its front end produces arching upward slightly because conflicting groove 12, so can promote the chucking power of the

first terminal

2 and 3 pairs of flexible flat cables 6 of second terminal, therefore, can promote the steadiness after flexible flat cable 6 is planted once again.

Above-mentioned detailed description is at a kind of preferable possible embodiments explanation of the utility model, but this embodiment is not in order to limit claim of the present utility model, all other do not break away from the equalization of being finished under the skill spirit that the utility model discloses to be changed and modifies change, all should be contained in the claim that the utility model contains.
