Please refer to Figures 1 and 2, the electrical connector of the present invention includes an insulating body 1, a terminal group 2 composed of several terminals assembled and held in the insulating body 1, and a metal shell 3 covering the insulating body 1 And two insulating diaphragms 41,42.

The insulating body 1 includes a base portion 11 and a docking portion 12 extending forward from the base portion 11. The base portion 11 is provided with a cavity 10 (see FIG. 5 ) and several slots 13 for accommodating terminal groups 2. There is an insertion hole 120 communicating with the cavity 10, and the insertion hole 120 is used for docking with a voice plug (not shown) to transmit voice signals.

2 and 3, the terminal set 2 includes a first terminal 21, the first terminal 21 includes a main body 210, a platform 211 bent downward from the main body 210 and extending forward, the platform 211 and The main body part 210 is roughly parallel, and the free front end of the platform part 211 is bent and extended with a guide part 212. The platform part 211 is provided with a protruding part 213 protruding downward, and the protruding part 213 is punched downward on the platform part 211. Therefore, the upper side of the platform portion 211 forms a concave point, and the lower side forms a convex point, that is, a raised portion 213 . One side of the main body 210 is provided with a welding leg 214 and a holding portion 215 . The upper surface of the base body 11 of the insulator body 1 is provided with a recessed portion 110 in the same shape as the main body portion 210 of the first terminal 21, and one side of the recessed portion 110 is provided with a through hole corresponding to the welding foot 214 and the holding portion 215 of the first terminal 21. Groove 113 and retaining groove 114, butt joint 12 is provided with the notch 121 that communicates with recessed part 110, and this notch 121 communicates with insertion hole 120 downwards (referring to Fig. 6), please refer to Fig. 2 and Fig. 4 shown, the first The main body portion 210 of a terminal 21 is accommodated in the recessed portion 110, the welding leg 214 and the holding portion 215 are respectively inserted into the through groove 113 and the holding groove 114 to have a holding effect, the platform portion 211 extends into the notch 121, and the raised portion 213 protrudes into the insertion hole 120 (refer to FIG. 6 ), so that the first terminal 21 is assembled in the insulating housing 1 . When the mating plug is inserted, the protruding portion 213 is electrically connected with the mating plug so as to transmit electrical signals.
