The mating contact member has at least one resilient, elongated beam that is progressively deflected along said predefined rotational skew when inserted within the female receptacle.

Abstract: A shielded plug assembly for mating a shielded multi-conductor cable assembly to a shielded receptacle connector and the method of making the same. The plug assembly employs a new type of unitary molded wire positioning member to position and secure the conductors prior to and during insertion of the wire positioning member into the plug assembly housing. The method includes cutting the wires after positioning within the wire positioning member and deforming a portion of the wire positioning member to securely hold the conductors therein. When the plug assembly is terminated to the conductors, the cooperation of the wire positioning member and the plug housing are such that the conductor ends are moved within the housing to assure alignment with corresponding insulation penetrating type terminals.

Abstract: A plug and receptacle connector assembly is used for interconnecting the conductors of a flat high density cable to circuits on a printed circuit board or the like. The plug contains a first set of contacts disposed on one side of the cable, each of which pierce the cable in order to make contact with alternate ones of the conductors. A second set of plug contacts are disposed on the other side of the cable and each of these plug contacts pierce the cable to make electrical contact with the other ones of the conductors in the cable. The plug contacts are L-shaped with the insulation piercing portions forming one of the legs of the L-shaped contacts. The insulation piercing portions of the plug contacts in the first set of contacts are positioned in a row closer to the rear end of the plug than the insulation piercing portions of the plug contacts in the second set of plug contacts.

Abstract: An edge connector having an opening for receiving a printed circuit board and having two opposed rows of contact for making electrical contact with conductive pads on opposite sides of a printed circuit board inserted into the connector. The connector is designed with the objective that when the two rows of contacts are in their "at rest" positions, the various contacts in one row will be in engagement with corresponding contacts in the opposed row at a location inwardly of the outer ends of the contacts, thereby electrically shorting the contact ends. The contacts of the connector are designed so that when a leading edge of a printed circuit board is inserted into the slot between the two opposed rows of contacts, such contacts will make electrical contact with conductive pads on both sides of the board, and after such contact is made, further insertion of the board will cause the contacts to separate at the location they had been shorted thereby completing a circuit through the board.
