Patent ID: 7841900

Claim:
An electrical connector comprising: a plurality of wafers aligned in parallel fashion, each wafer comprising: an insulative housing defining a mating surface and a mounting surface perpendicular to the mating surface, a plurality of passages concaved from the mounting surface, the insulative housing having a platform formed in each passage and two cavities defined on opposite sides of the platform, the platform having a pair of protruding portions formed thereon and disposed above the cavities respectively, each cavity having an opening defined in the mounting surface; and a plurality of contacts received in the passages of the insulative housing, each contact comprising a receptacle formed with a pair of legs, each leg having a preloaded portion, the preloaded portion being insertable into the cavity via the opening along a mounting direction perpendicular to the mounting surface while spreading out the legs; wherein said platform is formed with a pair of side walls, the distance between the side walls is larger than the distance between the pair of the legs, and said preloaded portions of the legs respectively resist against the side walls; wherein said platform defines an engaging hole between the pair of the side walls, the engaging hole extending through the mating surface and communicating with the passage for insertion of a pin of a mating connector.
