When the high-voltage output interface 4 is installed, only the high-voltage output interface 4 with the corresponding error prevention protrusion 31 can be plugged into the corresponding connection hole 11 . It can be easily imagined that the high-voltage input interface 3 can also be provided with an anti-error protrusion 31, and an anti-error hole 12 is installed on the corresponding input interface to ensure that the high-voltage input interface 3 is installed correctly. Certainly, the error-proof hole 12 can also be arranged on the high-voltage input interface 3 and the high-voltage output interface 4 , and the error-proof protrusion 31 can be arranged on the box body 1 .
