Generally, the conductive female plug and the conductive male plug of the power supply generate a large current at the moment of connection, so that a spark phenomenon occurs. In the embodiment, the conductive silica gel 242 is arranged at the insertion position of the conductive female plug 221 and the conductive male plug 241, so that ignition can be prevented when the conductive female plug 221 and the conductive male plug 241 are communicated, damage to the conductive part is avoided, and normal power supply of the battery pack is ensured. Specifically, since the conductive silicone 242 has a resistance, at the instant when the conductive male plug 241 and the conductive female plug 221 are powered on, the conductive silicone can reduce the current between the conductive male plug 241 and the conductive female plug 221, thereby avoiding the occurrence of the sparking phenomenon.

That is, the conductive silicone 242 contacts the conductive female plug 221 through the end surface thereof close to the conductive female plug 221 in the first direction, and contacts the conductive male plug 241 through the insertion groove 2421 thereof, so that at the instant when the conductive male plug 241 and the conductive female plug 221 are energized, the conductive silicone can be conducted with the conductive female plug 221 and the conductive male plug 241, and the instant current passing through the conductive male plug 241 and the conductive female plug 221 is reduced through the resistance thereof, thereby avoiding the influence on the transmission of the electric signal due to the burning caused by the ignition between the conductive male plug 241 and the conductive female plug 221, and ensuring the stability of the output of the power supply.

For example, the plugging groove 2421 of the conductive silicone 242 is U-shaped (as shown in fig. 5), and when plugging, two side groove walls of the plugging groove 2421 and two end surfaces of the conductive male plug 241 are in interference fit to generate extrusion, so that the conductive silicone 242 and the conductive male plug 241 are kept in full contact.
