Embodiment

Please consult Fig. 1, Fig. 2, shown in Figure 3 simultaneously, be three-dimensional exploded view and combination stereogram for three-dimensional exploded view of the present utility model, another angle, find out that by knowing among the figure electric connector structure of the present utility model is made up of an insulating body 1, complex conduction terminal 2, a bonnet 3 and pair of bolts 4.

Insulating body 1 is to be a long cuboid, this insulating body 1 is forwards to protrude out to form a docking part 11, be provided with plural terminals caulking groove 111 in this docking section 11, the rear of this docking section 11 is provided with plural location notch 112, and the end face dual-side of insulating body 1 respectively is provided with a recess 12, and this recess 12 is provided with the perforation 121 of a circle.

Conducting terminal 2 is made by metal material, and each conducting terminal 2 is to have a smooth base portion 21, and this base portion 21 is one contact sites 22 of elastic extension forwards, and the end of base portion 21 again bending downwards extend a straight weld part 23.

Bonnet 3 is formed by the upper plate portion 31 of insulation material and back board 32, front end face at back board 32 is convexly equipped with a plurality of guide vane end stops 33 forward, be that equi-spaced apart is provided with groove 331 on this guide vane end stop 33, and this bonnet 3 is provided with positioning rib 34 with respect to location notch 112 places of insulating body 1.
