Separation type plug and socket

A separation type plug and socket comprises two independent plugs which are independently connected with one end of a connecting bus through wires and can independently move relative to each other, wherein a metal insertion piece is arranged on each independent plug, the other end of the connecting bus is divided into a plurality of independent branch wires through switching points, three independent jacks which can independently move relative to one another are arranged on an end portion of each branch wire, and the three independent jacks on the end portion of each branch wire correspond to a firing line, a null line and a grounding line respectively. The separation type plug and socket is simple in structure and strong in applicability, the two independent plugs can freely move alone and can be matched with a socket with any jack arrangement form, the three jacks of each set of independent plug can independently move relative to one another so that the separation type plug and socket can adapt to an existi
