  • Patent number: 11189977
    Abstract: A hermaphroditic connector for use in single or multiple twisted-pair connectivity applications is constructed using a small number of parts having a simple but durable assembly. The connector housing comprises an elongated form factor that, when mated with a similar hermaphroditic connector, forms a rigid overlapping shield around the electrical contacts of the two connectors. While unmated, the conductive tines within the connector have a default curved profile that facilitates reliable connectivity with tines of a mating connector. When the connector is mated with a similar connector, the tines are deformed to a flatter profile by support plates within the connectors, yielding a shape more conducive to high-frequency signal applications. The shape of the tines also yields multiple in-line redundant contact points to ensure reliable connectivity without adding to the width of the connector.

  • Patent number: 9859663
    Abstract: Shields, wire connectors, crimping devices, and wire managers. At least some of the shields are used with a cable that includes a jacket surrounding wire pairs, and a different pair shield surrounding each wire pair. Such shields include a compressible member positioned adjacent end portions of a portion of the wire pairs. The compressible member presses a conductive member against the pair shield surrounding each wire pair in the portion of wire pairs. At least some of the wire connectors include a conductive body positionable alongside a selected wire having a connector surrounded circumferentially by an insulating jacket. The body includes a receptacle with a tapered opening defined between first and second edge portions of the body. As a portion of the selected wire passes through the opening into the receptacle, the first and second edge portions cut through the insulating jacket to contact the conductor.

  • Patent number: 8313346
    Abstract: A communications cable having a plurality of twisted wire pairs each having a substantially uniform twist rate along the cable. An elongated shielding separator is positioned between the twisted wire pairs and physically separates them from one another. The shielding separator has a plurality of electrically non-conductive separator sections positioned between the twisted wire pairs and a plurality of electrically conductive separator sections arranged in an alternating pattern with the non-conductive separator sections along the shielding separator. Each of the conductive separator sections has one of a predetermined number of section lengths and is arranged along the shielding separator such that the conductive separator sections are substantially aperiodic with the twist rates of the twisted wire pairs. Optionally, the cable includes a continuous or discontinuous outer cable shielding system enclosing the discontinuous shielding separator and the plurality of twisted wire pairs.

  • Patent number: 8235731
    Abstract: A substrate operable to construct a male-type connector, a female-type connector, and/or a multi-outlet module. The substrate has a plurality of circuits and an edge card male connector including contacts for each circuit. For each circuit, the substrate has a ground plane connected to one or more of the contacts for the circuit. The ground planes may be implemented as localized, electrically floating, isolated ground planes. The substrate may include multiple layers upon which portions of the circuits and ground planes may be disposed. The ground plane corresponding to each of the plurality of circuits may be located in close proximity to conductive elements of the circuit so as to provide a localized common ground to which energy can be conveyed from the conductive elements to thereby limit an amount of energy radiated outwardly from the conductive elements to surrounding conductors.

  • Patent number: 7714227
    Abstract: A cable junction box has a curved shape to at least part of its enclosure allowing for coiling of extra cable length into a desired service loop within the enclosure. The cable junction box has a cover with a mud ring integrated with a wall plate bracket to allow for interfacing with a wall and has a cable input to receive cabling into the enclosure. Attachment plates are located on the periphery of the enclosure to be selectively used to attach the cable junction box to a mounting bracket coupled to a wall stud. The attachment plates allow for flexibility in positioning of the cable junction box to be attached to the wall stud. The enclosure has connection locations for the front cover and other connection locations for the cable inlet to allow for further flexibility in positioning of the front cover and the cable inlet.

  • Patent number: 7713094
    Abstract: A communication connector including a plug and jack configured to lessen potential for crosstalk caused by unintended mode conversion coupling along wire pairs connected to tine pair 2 (tines T1 and T2) and tine pair 4 (tines T7 and T8). In the plug, twisted pair 2, connected to tine pair 2, and twisted pair 4, connected to tine pair 4, exchange lateral positions with one another thereby reducing differential voltage therebetween and unwanted transmission line mode conversion coupling. In the jack, cross-members and insulators laterally exchange longitudinal routing of the jack tine pair 2 with the jack tine pair 4 for those portions extending away from the plug engagement area of the jack. In particular, the longitudinal routing between tine T1 and tine T8 are laterally exchanged and longitudinal routing between tine T2 and tine T7 are laterally exchanged.
