More specifically, when the plug 200 is not rotated to a predetermined position (for example, rotated by a predetermined angle to a position where the plug pin on the plug is fully contacted with the corresponding power electrode on the socket), the protecting cover 30 always applies a force to the pressing block 22 through the force application part 305 during the rotation process, so that the pressing block 22 always compresses the pressing block spring 221, and the slider 23 also always compresses the slider spring 231, and at this time, the sliding mechanism is always in the open position, and the second contact 241 and the first contact 111 are always kept open.
