Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIG. 1 and FIG. 2 , the electrical connector of the present invention includes an insulating body 10 , a plurality of electrical terminals 20 fixed on the insulating body 10 , and a housing 30 covering the insulating body 10 .

The insulating body 10 is substantially in the shape of a cuboid, and defines an insertion slot 11 from front to back. A bottom wall of the insertion slot 11 defines a plurality of terminal slots 12 . The terminal slot 12 includes an accommodating slot 121 opened on the bottom wall of the insertion slot 11, a holding slot 122 opened on the side wall of the accommodating slot 121 and communicating with the accommodating slot 121, and a holding slot 122 opened on the rear wall of the insertion slot 11. Fixing groove 123. The insertion slot 11 has two side walls 111 , and a first fixing hole 1111 and a second fixing hole 1112 are respectively defined on the outside of the side walls 111 . The outer rear parts of the two side walls 111 of the insertion slot 11 protrude outwards and then extend upwards to form a limiting portion 1113 , and the limiting portion 1112 and the side walls 111 of the insertion slot 11 form a limiting hole 1114 . An accommodating hole 1115 communicating with the insertion slot 11 is defined inside the two side walls 111 of the insertion slot 11 from front to rear.

The electrical terminal 20 includes a base arm 21. The front end of the base arm 21 protrudes to both sides with two retaining portions 211. The front end of the base arm 21 extends obliquely upward and backward with an elastic contact portion 22. The rear end of the base arm 21 protrudes to both sides. There are two engaging parts 212 , the rear end of the base part 21 extends upwards to form a fixing part 23 , and the free end of the fixing part 23 extends to form a welding foot 24 .
