[Prior Art] According to the development of electronic technology, electronic products are increasingly popular, and battery connectors are used as connecting electronic products. The connectors of the required energy devices are also becoming more and more widely used. Referring to the first embodiment, a conventional battery connector 60 includes an insulative housing 61, a plurality of terminals 62 that are inserted into the insulative housing 61, and a metal shell 63 that is wrapped around the insulative housing 61. However, when the respective terminals 62 of the conventional battery connector 60 described above operate, mutual electromagnetic interference easily occurs. [New content] The main purpose of this creation is to provide a battery connector that can effectively prevent mutual electromagnetic interference with external sources in view of the above-mentioned drawbacks of the prior art. In order to achieve the above object, the battery connector of the present invention comprises an insulating body, a terminal set and a shielding case. The insulating body is provided with an accommodating chamber; the terminal group is composed of a plurality of conductive terminals and at least one grounding terminal, and is installed in the accommodating chamber; the shielding shell is wrapped around the insulating body, and the shielding shell is The lower edge extends forwardly and extends downwardly to form a contact leg that is in contact with the ground terminal. In summary, the shielded housing of the battery connector of the present invention is grounded by contacting the contact pins with the grounding terminal, thereby effectively preventing mutual electromagnetic interference with the outside. 3 M378486 [Embodiment] In order to explain the technical contents, structural features, objectives and effects of the present invention in detail, the embodiments are described below in detail with reference to the drawings. Referring to the second to fourth figures, the present battery connector 100 includes an insulating body 1, a terminal set 2, and a shield case 3. Referring to the third and fourth figures, the insulative housing 1 is substantially in the shape of a rectangular block. The insulative housing 1 is provided with a plurality of side-by-side receiving chambers 11 , and the rear side walls of each of the receiving chambers 11 are disposed in the receiving chamber 11 . There are two barrier walls 111 protruding from the protrusion. The insulative housing 1 protrudes outwardly from the lower portion of the rear wall to form two protrusions 12. The protrusion 12 defines a locking groove 121 extending through the upper and lower sides. The terminal group 2 is composed of a grounding terminal and a plurality of conductive terminals for connecting to a grounding plate on an external circuit board (not shown). The grounding terminal and the plurality of conductive terminals have the same shape and structure, wherein each of the terminals has a vertical plate-shaped retaining portion 21, and the upper end of the retaining portion 21 is curved upwardly and backwardly to form an elastic contact portion 22, and the elastic contact portion 22 The distal end of the retaining portion 21 is bent outwardly to form a soldering leg portion 24, and the distal end of the free end portion 23 is outwardly extended to form a convex end portion 231. The shield case 3 has a front wall 31, a rear wall 32, and two side walls (not shown) connecting the front wall 31 and the rear wall 32. The lower edge of the front wall 31 is bent forward and inclined downward to form a contact leg 311; the rear wall 32 is provided with two escape grooves (not shown) extending to the lower edge, and the rear wall 32 is in the escape groove. The upper side groove edge extends downward and then bends upward to form a soldering leg 321 for improving the soldering reliability. Referring to the second figure, when the battery connector 100 of the present invention is assembled, the terminals of the terminal group 2 are respectively disposed in the accommodating chamber 11 of the insulative housing 1, and the elastic contact portion 22 and the soldering portion 24 are exposed to the insulation. Outside the body 1, the convex teeth 231 are hooked on the block 4
