Electric connector and auxiliary connection device thereof

The invention discloses an electric connector and an auxiliary connection device thereof. A signal connection end and a third auxiliary conductive part are arranged, and the assembly distance of the signal connection end and the third auxiliary conductive part is smaller than that of a first conductive part and a third conductive part and/or a second conductive part and a fourth conductive part. In the process of assembling a male end and a female end, before a power supply loop of the electric equipment is formed, the third auxiliary conductive part can connect the two terminals in the signal connection end, so that the power supply firstly provides an indication signal for the processor, the processor is conveniently triggered to control the power supply to suspend power supply for a preset time length, and corresponding control is performed according to the indication signal by setting a reasonable preset time length. Therefore, the power supply can supply power after the power supply loop of the electric
