Detailed ways

In order to make the above purpose and structural features of the present utility model more clear to those familiar with the technology, the present utility model will be further described with a specific embodiment in conjunction with the accompanying drawings.

Please refer to Figure 1, which is a specific embodiment of the improved structure of the battery connector of the present invention. The battery connector 5 includes an insulating body 1, contact terminals 2, and positioning inserts 3; please refer to Figure 2, Holding arms 12 protrude from both sides of the butt joint surface of the elongated insulating body 1, and a plurality of accommodating grooves 14 for placing the contact terminals 2 are provided between the holding arms 12 at a specific distance, and the accommodating grooves 14 is a non-penetrating channel, a channel 143 is provided in the accommodation groove 14, the channel 143 is located at the upper end of the accommodation groove 14, and the bottom of the channel 143 is a finger 141, and the finger 141 and The bottom wall of the accommodating groove 14 is connected; a protruding portion 11 protruding forward is provided on the lower part of the two holding arms 12 of the battery connector 5, which is vertically long insulated body 1, and the protruding portion 11 is parallel to the holding arms 12. , and is connected with the base 112 and share a low plane 111. At the bottom of the rear side of the insulating body 1, there is a receiving groove 13 for the positioning insert 3 to be embedded and fixed. Extending, and at the same time set downwards as a through area 131, which is for the positioning insert 3 to be accommodated in the receiving groove 13 for the pin 33 to be inserted into the circuit board. The plane 111 is high in order to provide a more stable clamping effect for the positioning insert 3 .

As shown in FIG. 2, the contact terminals 2 are in the shape of a plate, and the front part of each contact terminal 2 protrudes to form a main body part 24 that is electrically connected with the mating connector. The rear ends of the contact terminals 2 The part is placed in the accommodating groove 14 provided by the insulating body 1 of the battery connector 5, and a positioning arm 23 protrudes horizontally from the top of the rear end, and a recessed locking part 22 is formed below the positioning arm 23. The lower portion 22 forms a guide pin 21 that is vertically bent and extends downward; the positioning arm 23 is interferingly positioned in the groove 143 provided in the accommodating groove 14 of the insulating body 5, and the locking portion 2 is engaged with the insulating body 5. The finger portion 141 provided on the body 1, when the contact terminal 2 is placed in the accommodating groove 14 for positioning, the guide pin 21 is placed in the accommodating area 142, and the end edge of the guide pin 21 abuts against the edge of the accommodating groove 14 The bottom wall makes the contact terminal 2 firmly positioned.

As shown in Figure 3, the structure of the positioning inserts 3 is mainly composed of the main body 31 as the positioning, and the horizontal end flanks of the main body 3 are provided with thorns 32, and these thorns 32 are beneficial to the main body. When 31 is positioned, an interference positioning effect is generated, and the positioning pin 33 is formed by vertically bending and extending downward from one side of the main body 31 .

As shown in Figure 4, the docking connector 4 for matching with the battery connector 5 is provided with a slot 41 for the battery connector 5 holding arm 12 to be inserted in the corresponding side of the docking connector 4, the two slots A plurality of insertion slots 42 are provided between the 41, and conductive terminals (not shown) are embedded therein.

As shown in FIGS. 5 and 6 , there is a certain distance between the welding plane of the battery connector 5 and the upper and lower sides of the isolation interface 113 , forming an effective isolation space 71 , which facilitates the soldering of the terminal leads 21 to the circuit board 7 .
