Abstract

An electrical connector defines an insertion port and comprises an insulative housing, a plurality of contacts retained in the insulative housing, a reinforcing plate retained in the insulative housing, and a metal shell covering the insulative housing. The contacts have two grounding contacts, two power contacts, and a plurality of signal contacts. Each contact comprises a contacting portion exposed beyond the insulative housing, a slant portion extending forwardly from the contacting portion and retained by the insulative housing, and a soldering portion extending backwardly from the contacting portion. Each contact has a bent portion connecting between the contacting portion and the slant portion. The bent portions of the grounding contacts are farther away from the insertion port than those of the power contacts but nearer to the insertion portion than those of the signal contacts for both hot plugging and better grounding performance.
