Abstract

An electrical connector is provided for both power and data transmission. The electrical connector comprises an electrical plug (100) having a plurality of pins (131˜138) and an electrical socket (200) having a plurality of passageways (220) which are arranged corresponding to the plurality of pins (131˜138). The pins (131˜138) of the plug comprise at least one signal pin (131, 136), two or more positive power pins (133, 134) and two or more negative power pins (132, 135). The pins (131˜138) of the plug can be disposed such that the positive power pins (133, 134) and the at least one signal pin (131, 136) are positioned on opposite sides of the negative power pins (132, 135).
