Abstract:
1. An electrical connector having a first mating slot and a second mating slot vertically stacked above the first mating slot, each mating slot extending transversely and facing forwardly for receiving a respective front card edge of a mating plug therein, comprising: a plurality of first contacts having contacting cantilevers transversely arrayed in the first mating slot; a plurality of second contacts having contacting cantilevers transversely arrayed above the first contacts; a plurality of third contacts having contacting cantilevers transversely arrayed above the second contacts and in the second mating slot; and a plurality of fourth contacts having contacting cantilevers transversely arrayed above the third contacts; wherein the second mating slot is backwardly offseted from the first mating slot, and the contacting cantilevers of the third contacts are backwardly offseted from the contacting cantilevers of the second contacts, thereby avoiding the interference of the contacting cantilevers of the second contacts and the third contacts when the two mating slots are mated with two front card edges of a mating plug; wherein an unitary housing having a cavity receiving the first to fourth pluralities of contacts, wherein the housing has a front protrusion with the first mating slot defined therein and a rear step face above the front protrusion with the second mating slot defined therein; and wherein a metal cage having a top wall, a bottom wall and a pair of side walls jointly defining a passageway opening forwardly, the metal cage further having a rear vertical wall jointly with the to wall and the pair of side walls defining a cavity, the cavity communicating a bottom open defined in the bottom wall, the housing being received in the cavity with the contacts extending out through the bottom open, and the first and the second mating slots communicating the passageway.
