  • Patent number: 6634893
    Abstract: An electrical connector (1) includes an insulative housing (10) and a number of contacts (28) attached to the housing. The contacts each have a contact tail (36) downwardly extending beyond a mounting surface (32) of the insulative housing for inserting into throughholes (42) of a PCB (40). The contact tails are overlapped in pairs and each pair of contact tails is inserted into the same throughhole of the PCB. Some pairs of contact tails, called retention contact tails (68), have protrusions (52) deviating from each other for bearing against peripheral walls of the throughholes of the PCB thereby producing retention force. The other pairs of contact tails, called non-retention contact tails (70), do not have protrusions and do not interfere with peripheral walls of the other throughholes thereby reducing the insertion force. The retention contact tails can be modified to the non-retention contact tails by severing the protrusions therefrom.

  • Patent number: 6575791
    Abstract: An electrical connector (1) includes an elongate insulative housing (12) defining a number of cavities (22) in a longitudinal direction (X) thereof, a number of groups of contacts (12) respectively received in corresponding individual cavities of the housing. The groups of contacts are arranged in two rows in a traverse direction (Y) of the housing. Each group of contacts includes at least two conductive contacts gathered side by side in the corresponding individual cavity in the X direction. The contacts each are such stamped and assembled to the housing that its dimension (T) in the X direction is much less than its dimension (W) in the Y direction, which reduces its occupied room in the housing in the X direction without reducing its strength.
