Embodiment

For describing technology contents of the present utility model, structural feature and purpose of being reached and effect in detail, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 1, the utility model electric connector 100 comprises an insulating body 1, plurality of terminals 2 and a metal baffle 3.

See also Fig. 2 and Fig. 3, insulating body 1 is provided with a receiving space 11, and insulating body 1 is provided with plurality of terminals groove 12, and terminal groove 12 is connected with described receiving space 11.Insulating body 1 both sides offer a fluting 13 that is connected with receiving space 11 respectively, both sides, insulating body 1 upper surface are respectively equipped with a guide ramp 17, insulating body 1 left and right sides sets to the concave respectively and forms a support slot 14, insulating body 1 both sides outwards are convexly equipped with respectively and form one first projection 15 and one second projection 16, first projection 15 and second projection 16 stagger up and down mutually, can avoid using on the mould of plastics slide block, thereby but simplified structure; First projection, 15 upper surfaces are recessed to form downwards that the front end upper surface is recessed to form one second stopper slot 161 downwards on one first stopper slot 151 and an accepting groove 152, the second projections 16.

See also Fig. 2, each terminal 2 includes a holding parts 21, and back bends and be tilted to the weld part 23 that the contact site 22 that extends to form and is extended to form by holding parts 21 rear ends downwards by holding parts 21 front ends.

Please continue to consult Fig. 2, metal baffle 3 has a upper plate 31, a back plate 37 that is extended to form downwards by upper plate 31 posterior edges reaches the biside plate 32 that is extended to form respectively by upper plate 31 left and right sides edge downwards, the shell fragment 33 that die-cut formation one is extended to the inside on the side plate 32, shell fragment 33 have an elastic arm portion 331 and by the elastic arm portion 331 terminal elastic contact parts 332 that extend to form that bend.Biside plate 32 lower limb approximate mid-section places extend to form a banking stop 35 respectively downwards, and banking stop 35 ends extend to form a leg 36 to a side.
