【Detailed ways】

The specific implementation of the electrical connector of the present invention will be described in detail below in conjunction with the accompanying drawings.

Please refer to FIG. 1 to FIG. 4 , the electrical connector 100 of the present invention is welded to a circuit board for docking with a mating electrical connector, and includes an insulating body 1 and a conductive terminal 2 assembled in the insulating body 1 .

The insulating body 1 has an upper surface 11 and a bottom surface 12 opposite to the upper surface 11, including two longitudinal side walls 13, two transverse end walls 14, and a receiving space 15 surrounded by the two side walls 13 and the two end walls 14. , wherein the insulating body 1 is further provided with a docking portion 16 protruding upward from the bottom surface 12 in the center of the housing space 15, the docking portion 16 is roughly rectangular, and a number of housing grooves 161 are provided on both sides, and the housing grooves 161 and the housing space 15 through each other, and an eaves 162 extend above the accommodating groove 161 ; the outside of the side wall 13 is provided with a holding groove 131 for holding the conductive terminal 2 ; the bottom surface 12 of the insulating body 1 has a bottom plate 17 .

The conductive terminal 2 includes a main body 21 , an elastic portion 22 bent and extended from the main body 21 , a bent portion 23 extending upward from the other end of the main body 21 and then bent and extended, and a holding portion 24 held in the holding groove 131 And the welding part 25 extending from the clamping part 24 to the outside of the insulating body 1, the main body part 21 is arranged at the bottom of the insulating body 1; The curved portion 221 on the side and the contact portion 222 protruding into the receiving space 15, the curved portion 221 is located below the eaves 162, the contact portion 222 protrudes from the vertical surface where the eaves 162 is located, and the curved portion 221 is provided with a bending direction and the eaves 162 The concave portion 2211 extending in the same direction, through the setting of the concave portion 2211, the conductive terminal 2 can be inserted from the top of the insulating body 1 without being hindered by the eaves 162; there are several barbs (not marked ), interfering with the holding groove 131 to respectively realize the fixing of the conductive terminal 2 and the insulating body 1; the bending portion 23 abuts against the side wall 13 of the insulating body 1; , located on the outside of the insulating body 1, for welding with the circuit board.
