Detailed ways

In order to illustrate the technical content, structural features and the purpose and effect of the utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIG. 1 , the electrical connector 100 of the present invention includes an insulating body 1 , a plurality of terminals 2 and a metal shielding body 3 .

Please refer to FIG. 2 and FIG. 3 , the insulating body 1 is provided with a receiving space 11 , and the insulating body 1 is provided with a plurality of terminal slots 12 , and the terminal slots 12 communicate with the receiving space 11 . Both sides of the insulating body 1 are respectively provided with a slot 13 communicating with the receiving space 11, a guiding slope 17 is respectively provided on both sides of the upper end surface of the insulating body 1, and the left and right sides of the insulating body 1 are respectively recessed to form a holding groove. 14. Both sides of the insulating body 1 protrude outward to form a first bump 15 and a second bump 16. The first bump 15 and the second bump 16 are staggered up and down to avoid using sliders on the plastic mold. , so that the structure can be simplified; the upper surface of the first protrusion 15 is recessed downward to form a first limiting groove 151 and a receiving groove 152, and the upper surface of the upper front end of the second protrusion 16 is recessed downward to form a second limiting groove 161 .

Please refer to FIG. 2, each terminal 2 includes a holding portion 21, a contact portion 22 formed by bending the front end of the holding portion 21 back and extending obliquely upward, and a welding portion 23 formed by extending downward from the rear end of the holding portion 21. .
