  • Patent number: 5692090
    Abstract: An end connector for fiber optic transport cables. A cable clamp received within a passageway of a housing which receives the cable is provided to hold the cable in a secured position so as to resist rotational and longitudinal forces applied to the cable. Support coupling units are provided both internal and external the equipment which the cable is to be connected to. The coupling units allow the end connector to be coupled to and decoupled from the equipment without unnecessary rotation of the end connector and cable and without having to remove the cable from the end connector. Grounding components are provided for grounding conductive members associated with the cable so as to prevent damage due to voltage surges and to prevent RF signal leakage.

  • Patent number: 5632651
    Abstract: A radial compression type coaxial cable end connector has a connector body comprising a tubular inner post extending from a front end to a rear end, and an outer collar surrounding and fixed relative to the inner post at a location disposed rearwardly of the front post end. The outer collar cooperates in a radially spaced relationship with the inner post to define an annular chamber with a rear opening. A fastener at the front end of the inner post serves to attach the end connector to a system component. A tubular locking member protrudes axially into the annular chamber through its rear opening. The tubular locking member is integrally coupled to the connector body and is displaceable axially between an open position accommodating insertion of the tubular inner post into a prepared cable end, with an annular outer portion of the cable being received in the annular chamber, and a clamped position fixing the annular cable portion within the chamber.

  • Patent number: 5571028
    Abstract: An end connector for a coaxial cable has a rotatable nut with an internal thread configured and dimensioned to coact in threaded engagement with a complimentary external thread on a system component. A circular seal element is contained within and axially fixed with respect to the nut. The seal element is deformable into a configuration lining at least a portion of the internal thread to thereby establish a barrier to the penetration of moisture between the interengaged internal and external threads.

  • Patent number: 5514001
    Abstract: The connector of the invention is particularly suited for use in combination with a coaxial cable and an equipment port having an internal first conductor. The end connector of the invention includes a connector element, a deflecting unit and a component interlocking unit. The connector element has one end adapted to be secured to the coaxial cable and includes a tubular connector wall at an opposite end surrounding a second electrical conductor. The connector wall is configured and dimensioned to axially receive a tubular port wall therein, with the first and second conductors being normally spaced one from the other. The deflecting unit is responsive to axial reception of the port wall in the connector wall for deflecting one of the conductors into electrical contact with the other of the conductors. The interlocking unit is associated with the port and connector walls for establishing an interlocked relationship between the equipment port and the connector element.

  • Patent number: 5456614
    Abstract: A coaxial cable end connector includes a tubular post having a first flange at a front end thereof and a port fastener rotatably supported on the front end of the post, the fastener having a second flange adapted to coact in mechanical interengagement with the first flange. The first and second flanges establish a non-planar interface of interengagement which acts as a signal seal in response to being interengaged. The first flange includes a surface indentation which coacts with a surface protuberance of the second flange in response to the fastener being connected to a signal port. In addition, an interference protuberance associated with the fastener coacts with an inclined surface associated with the tubular body to establish another non-planar interface of interengagement which acts as an additional signal seal.

  • Patent number: 5371827
    Abstract: An end connector for connecting a fiber optic cable to a port associated with a piece of equipment, the cable having at least one optic fiber and at least one other support member surrounded by a jacket. The end connector includes a housing member having a front end and a rear end, the housing member defining a passageway extending from the rear end to the front end for passing the cable therethrough. A coupling unit is provided for coupling the housing member to the port. A clamp unit is received in the passageway and is adapted to at least partially surround the cable, the clamp unit being adjustable between an expanded state which accommodates movement of the cable with respect to the housing and a constricted state which fixedly secures the cable with respect to the housing. A clamp adjustment unit is provided for adjusting the clamp unit between the expanded and the constricted states.

  • Patent number: 5283853
    Abstract: An end connector for connecting a tubular support structure having at least one optic fiber associated with a fiber optic cable, to a terminal of an associated device. A housing member is configured with a passageway from a front end to a rear end for passing the tubular support structure therethrough. A clamping portion including a flexible sleeve and compression grommet are received and supported by both the housing and a compression nut which couples to the rear end of the housing. As the compression nut is threaded onto the rear end of the housing, the compression grommet is compressed, and in turn the flexible sleeve constricts to apply clamping pressure to the tubular support structure holding the optic fibers.

  • Patent number: 5195906
    Abstract: An end connector for connecting a coaxial cable to a port having a tubular body with front and rear end portions, a cable attachment section associated with the rear end portion for attaching the connector to the cable, and a port attachment section associated with the front end portion for attaching the connector to the port. The port attachment means includes a split ferrule defining a plurality of partially cylindrical resilient fingers, the fingers having inward arcuate projections defining a circumferential ridge adapted to engage the port. The split ferrule defines an inner surface which is inwardly tapered to enhance port to connector contact. A locking sheath is disposed about the front end portion of the tubular body and is adapted to engage an outer surface of the split ferrule so as to restrict the resiliency of the resilient fingers.
