ELECTRICAL CONNECTOR ASSEMBLY

Abstract

 In an electrical connector assembly, an electrical contacting portion, a transition portion and a fixing portion of each of the first power terminal and the second power terminal are identical to those of each of the first signal terminal and the second signal terminal in size and shape, respectively. The fixing portion of the first power terminal is inserted into an insulation body of the male connector by a first depth, the fixing portion of the first signal terminal is inserted into the insulation body of the male connector (100) by a second depth, and the first depth is greater than the second depth. The fixing portion of the second power terminal is inserted into an insulation body of the female connector (200) by a third depth, the fixing portion of the second signal terminal is inserted into the insulation body of the female connector by a fourth depth, and the third depth is greater than the fourth depth. Therefore, during assembling, the power terminals contact with each other before the signal terminals contact with each other, because the power terminals are inserted into the insulation bodies more deeply than the signal terminals. In this way, the male connector and the female connector may achieve a hot plug-in function.
