PLUG

The utility model relates to a plug comprising an upper shell, a lower shell, and pins. The utility model is characterized in that a blocking body is arranged in the lower shell; both sides of the block body are provided with a wire connection slide block; a pressure spring is arranged between the block body and the wire connection slide block; the pins are arranged on the wire connection slide block. The utility model solves the problem that a multi-purpose socket or a wire connection board is necessarily matched with plugs of different types and specifications. The separation distances of pins can be regulated in order to adapt to the multi-purpose socket or the wire connection board. The applicable plug is worth of popularization.
