When the five-hole socket is used, only one of the 3pin jack and the 2pin jack can be used, and when one socket is inserted, other sockets are inevitably blocked from being inserted, so that the 3pin jack and the 2pin jack cannot be used simultaneously. When the electrical equipment is connected more, more sockets need to be connected to meet the requirement, and the defects of inconvenient use and increased cost are caused.

The 3pin jack and the 2pin jack of the five-jack socket in the prior art are arranged on the same surface, such as the upper surface, of the plug board, and when a two-pin plug corresponding to the 2pin jack is inserted into the socket, the connection of the plug can be bent along the transverse direction. Therefore, when the electrical equipment with the two-pin plug is used in the five-hole socket, the connection wire is inevitably bent due to the plugging position of the plug, and even the cable is broken. In addition, when the electrical equipment with the two-pin plug uses the five-hole socket, the two-pin plug is connected with the socket unstably and even separated from the jack easily due to the dragging of the cable.

The terminal of the five-hole socket in the prior art is connected to the live conductor, the neutral conductor and the ground conductor inside the five-hole socket in a welding or screw connection mode. The manufacturing process and the assembly process of the wiring terminal of the five-hole socket are complex, a plurality of working procedures are needed for processing, and the labor cost is high. The wiring end of the five-hole socket in the prior art is easy to have the problems of screw looseness, unstable wiring, welding seam and the like, so that electric sparks are generated when a power plug is inserted, and the use safety of a user is influenced.
