【Detailed ways】

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

Please refer to FIG. 1, the battery connector 100 is composed of an insulating body 1, a number of conductive terminals 2, a plug-in reinforcing plate 3 inserted in the middle of the front end of the insulating body 1, and a welded reinforcing plate located on both sides of the insulating body 1. Plate 4 constitutes. Wherein, the insulating body 1 is roughly "L"-shaped, and it is provided with a short side portion 12 and a long side portion 11 perpendicular thereto. The insulating body 1 is provided with an insertion groove 13 in the long side portion 11. The insertion groove 13 runs through front and back and one end of the bottom is provided with a groove 131, and the insulating body 1 is provided with a receiving groove 14 in its short side 12, and the insertion groove 13 and the receiving groove 14 are penetrated in the insulating body 1 An "L"-shaped accommodation groove (not shown) is formed for accommodating the conductive terminal 2 .

Both ends of the long side 11 of the insulating body 1 are provided with receiving holes 112 for inserting the welded reinforcing plate 4 , and recessed holes 111 for inserting the inserting reinforcing plate 3 are provided between the insertion grooves 13 .

One end of the conductive terminal 2 is provided with a contact portion 21, and the other end is provided with a welding portion 23. There is a bent connection portion 22 between the contact portion 21 and the welding portion 23, and several In the arc-shaped section, one end of the connecting portion 22 is provided with a holding portion 24 close to the welding portion 23, and the two sides of the holding portion 24 are extended with a plurality of barbs 241 fixed on both sides of the insertion groove 13, and the holding portion 24 is provided with A through hole 242, the side of the through hole 242 close to the contact portion 21 extends downward away from the insertion direction of the conductive terminal 2, and a clamping portion 243 is provided, and the clamping portion 243 is clamped in the through groove 131 at the bottom of the insertion groove 13 Inside, the opening area of the through hole 242 is larger than the planar area of the clamping portion 243 . 242 can also be oval or other shapes, which are used to reduce the rigidity of the root of the barb 241 .
