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. 3 , the battery connector 100 of the present invention is assembled on a circuit board 40 and plugged with a docking connector (not shown in the figure) and conducts. The battery connector 100 includes an insulating body 10, a plurality of terminals 20 and A fixing piece 30 .

Please refer to Fig. 3 to Fig. 6, described insulator body 10 is rectangular block, is made of front wall, rear wall, top wall, bottom wall and two side walls (not marked in the figure), on the front wall of insulator body 10 A plurality of terminal slots 11 arranged horizontally and penetrating to the bottom wall are provided. The middle part of the top wall is recessed downwards with a receiving groove 12, and both sides of the receiving groove 12 are provided with an elastic arm groove 13 which runs through the insulating body 10 up and down, and the middle part of the receiving groove 12 is provided with a buckle groove 14 near the front end. There is a groove 15 on the bottom wall corresponding to the plurality of terminal grooves 11 and the groove 15 communicates with the terminal grooves 11 . The width of the groove 15 is greater than the width of the terminal groove 11 .

The fixing member 30 has a plate-shaped base 31 and elastic arms 32 formed by bending and extending downwards from both sides of the base 31 . A buckle portion 312 is formed by bending and extending. The base 31 is pressed against the top wall of the insulator body 10 , a slit 33 is formed at the lower ends of the elastic arms 32 to the middle of the elastic arms 32 , and a hook 321 is formed on both ends of the elastic arms 32 .

A welding hole 41 corresponding to the spring arm 32 of the fixing member 30 is opened at the front end of the circuit board 40 .

The plurality of terminals 20 are assembled in the terminal groove 11 of the insulating body 10, and the lower surface of the terminals 20 is welded on the circuit board 40. When the terminals 20 are welded on the circuit board 40, it is necessary to apply solder paste on the circuit board 40 where the terminals 20 are welded. , so the design of the bottom wall groove 14 can prevent the bottom wall of the insulating body 10 from damaging the solder paste.
