Referring to fig. 1, the present invention provides a battery pack connection plug 100 and a battery pack using the battery pack connection plug 100.

In the embodiment of the present invention, the battery pack connecting plug 100 includes an insulator 10 having a plug hole 101 at one end thereof and a plurality of pins 20 disposed in the plug hole 101 at intervals and connected to the insulator 10, the plurality of pins 20 includes a positive pin 21 for electrically connecting to a positive electrode of the battery pack, a negative pin 22 for electrically connecting to a negative electrode of the battery pack, and a communication pin 23 for communicating with the battery pack, wherein the communication pin 23 includes a plug portion 231 located in the plug hole 101, the plug portion 231 includes a plurality of conductive units 2311 connected in sequence, and two adjacent conductive units 2311 are connected in an insulated manner, it can be understood that each conductive unit 2311 is used as a connection point for inputting a signal, so that one communication pin 23 can receive input of multiple signals, thereby reducing the number of communication pins 23, not only facilitating the compact design of the battery pack connecting plug 100, the volume of the communication pin 23 is also conveniently increased, so that the mechanical strength of the communication pin 23 is improved, and the plugging performance and the service life of the battery pack connecting plug 100 are further improved. In the present embodiment, the number of the conductive units 2311 is three, that is, the communication pin 23 is used for receiving three-way signal input.

Further, in one embodiment, the plug portion 231 is cylindrical to facilitate the connection of the communication pin 23, that is, each conductive unit 2311 is cylindrical and coaxially disposed, and an insulating ring 232 is disposed between two adjacent conductive units 2311 to insulate and connect the two adjacent conductive units 2311. Meanwhile, in order to improve the plugging performance of the communication pin 23, the plurality of conductive units 2311 include a first conductive unit 2312 and at least one second conductive unit 2313 (i.e., the number of the second conductive units 2313 is two in the present embodiment), the first conductive unit 2312 is close to the top end of the patch hole 101 and includes a connection section 2314 close to the adjacent second conductive unit 2313 and a guide section 2315 connected with the connection section 2314, and the outer diameter of the guide section 2315 is smaller than that of the connection section 2314, so that the guide section 2315 is easier to insert into the battery pack due to the smaller diameter, thereby achieving the purpose of improving the plugging performance of the communication pin 23. Preferably, the end of the guide section 2315 remote from the connecting section 2314 is further provided with a tapered guide surface 2316 to further enhance the mating performance of the communication pin 23.

Further, in one embodiment, the insulator 10 is made of a plastic material (e.g., PC flame retardant plastic) with high temperature resistance and flame retardant effect, and the contact pin 20 is made of copper metal, and in order to improve the connection firmness between the insulator 10 and the contact pin 20, the insulator 10 and the contact pin 20 are integrally formed by injection molding, so as to improve the waterproof performance of the battery pack connection plug 100. Preferably, in order to fix the battery pack connection plug 100, a pair of fixing seats 102 is formed by protruding from an outer side of one end of the insulator 10, where the socket 101 is provided, and each fixing seat 102 is provided with a fixing hole 1021, and the battery pack connection plug 100 is fixed on the battery pack by passing a screw through the fixing hole 1021.

For example, in the present embodiment, the patch jack 101 is a square hole, and two adjacent corner positions of the patch jack 101 form a pair of mating surfaces 103 by chamfering, so that the patch jack 101 can be positioned by the pair of mating surfaces 103 during patch connection, so that the patch plug 20 can accurately complete patch connection, and the adverse phenomenon that the patch plug 20 is bent or folded is effectively avoided.

In summary, the battery pack connection plug 100 is sequentially insulated and connected by the conductive units 2311 to form the communication pins 23 for communication connection, which cannot reduce the number of the communication pins 23, but also can enhance the volume and strength of the communication pins 23, thereby achieving the purpose of improving the plugging performance.
