  • Patent number: 7753717
    Abstract: A method and system for terminating a cable into a plug using a plug assembly system. Wires of the cable are exposed and dressed on to a shield. A plug body is placed over the shield. The wires are fed into wire insertion holes of the plug body. A contact holding member is placed on the plug body. A crimping tool crimps the contacts in the contact holding member through the plug body into and through the wires to achieve mechanical and electrical connection between the wires and the contacts. A cover may be used to cover the plug body, shield and wires. A crimp ferrule may be used to crimp the wires to the shield.

  • Publication number: 20070270044
    Abstract: A jack capable of handling both Category 6 and Category 7 communications. The jack comprises a shield and a housing inside the shield. Eight contacts are disposed on a first side of the housing, each contact including a contact portion effective to touch a corresponding contact of a plug when the plug is inserted into the jack, and a first end portion effective to be inserted into a circuit board. Four contacts are disposed on a second side of the housing opposite the first side, each contact including a contact portion effective to touch a corresponding contact of a plug when the plug is inserted into the jack, and a first end portion effective to be inserted into a circuit board. The first ends of the first contacts and the second contacts exit the second side of the housing. A shield is disposed between the contacts on the first side of the housing and between the contacts on the first side of the housing and contacts on the second side of the housing.

  • Publication number: 20050245125
    Abstract: A high performance, high capacitance gain, electric connector for data transfer applications. At least eight sequentially positioned elongate contact members are connected in a series of signal pairs. A first signal pair includes a fourth contact member and a fifth contact member. A second signal pair includes a third contact member and a sixth contact member. In addition, a third signal pair comprises a first contact member and a second contact member. Finally, a seventh and an eighth contact member are in a fourth signal pair. One member of each contact member pair is configured differently from the other member of the pair, the respective contact members being oriented relative to one another such that they substantially remain in generally parallel planes, but define non-parallel paths. Each of the third and fifth contact members mounts a plate-like extension oriented in a first direction and in respective planes generally parallel to one another.

  • Publication number: 20050106929
    Abstract: Modular plug for terminating a cable having twisted signal pairs of wires including a plug housing having contact blade-receiving slots at a front end and defining a longitudinally extending cavity opening at a rear end and a strain relief member defining a channel for receiving the cable. A wire aligner is interposed between the strain relief member and the housing and arranged at least partially in the cavity. The wire aligner aligns the wires of the cable into specific position relative to the slots and crimps the cable when received in the channel of the strain relief member. To crimp the cable, the wire aligner is formed with retention fingers which exert an inwardly directed force against the cable when receive din the channel of the strain relief member.

  • Patent number: 6419526
    Abstract: A multi-port modular jack including an outer housing part, inner housing parts arranged in the outer housing part to define plug-receiving receptacles receivable of mating plugs, and an optional shield surrounding the jack. The outer housing part having a top wall, a bottom wall and a front face having a mid-portion arranged substantially parallel to and between the top and bottom walls. The front face defines a first row of apertures between the mid-portion and the top wall and a second row of apertures between the mid-portion and the bottom wall. Each aperture in the first row has a plane of symmetry offset in relation to a plane of symmetry of each aperture in the second row such that only a portion of each aperture in the first row is directly opposite the opposed apertures in the second row. Vents are formed in the outer housing part to allow for the passage of air through the jack.

  • Patent number: 6409535
    Abstract: Modular plug offering improved near-end crosstalk (NEXT) performance including a housing defining a plurality of terminal-receiving slots, wire-receiving channels each situated in communication with a slot and a longitudinal cavity extending from a rear surface of housing to the channels and which is in communication with the channels. The plug includes contact terminals situated in the slots and a load bar arranged in the cavity. The load bar defines wire-receiving channels for receiving the wires of the cable. At least first and second wire-receiving channels are arranged in a first plane parallel to the upper and lower faces of the load bar and at least third and fourth channels are arranged in a second plane parallel to the first plane. The first and second channels are adapted to receive two of the wires of the cable which operatively form part of a first circuit during use. A cable-plug assembly including a cable terminated at one or both ends by such plugs is also disclosed.

  • Patent number: 6402559
    Abstract: A modular plug including a housing made of dielectric material including a plurality of parallel, spaced, longitudinally extending terminal-receiving slots at a forward end and a longitudinal cavity extending from a rear face thereof forward. Each terminal-receiving slot receives a respective terminal blade. The plug also includes a load bar assembly which is inserted into the cavity and includes a load bar housing defining conductor-receiving channels in substantially parallel rows or levels arranged such that each level receives at least one pair of conductors, preferably a pair of conductors which operatively forming a circuit during use. Preferably, the channels adapted to receive the conductors forming conductor pair #1, conductors 4 and 5 according to a standard convention, and the channels adapted to receive the conductors forming conductor pair #3, conductors 3 and 6, are situated in levels distant from one another to thereby reduce crosstalk between these conductor pairs.
