  • Patent number: 6619876
    Abstract: A coaxial connector of the type wherein an inner connector member of a female connector is adapted for secure engagement with a connector member of a male connector. The coaxial connector is positioned around the connector member of the male connector and the connector member of the female connector when the coaxial connector is in its locked position. A spring basket with an angular frontal surface is positioned around the connection member of the male connector. A sleeve with an angular internal surface for engaging the angular frontal surface of the spring basket is reciprically positioned around the spring basket and the connection member of the male connector. The sleeve has at least one locking groove that extends substantially parallel to the major axis along a portion of the body thereof. A spring nut is provided with a hollow front end disposed within the sleeve and at least one upstanding locking finger disposed within the at least one locking grove of the sleeve.

  • Patent number: 6454601
    Abstract: A connector for connecting a coaxial cable to radio frequency (RF) equipment in which an inner contact is positioned inside a channel within a conductive metal body and an electrically insulating material is injected into the channel, thereby providing insulation between the contact and the metal body and retaining the contact in position within the body. Connecting a coaxial cable to RF equipment is simplified and soldering of the inner contact is avoided.

  • Patent number: 5944556
    Abstract: A connector assembly for a coaxial cable having an outer conductor, an inner conductor, and a dielectric spacer between the two conductors. The connector comprises a generally cylindrical outer connector adapted to be mounted on the outer surface of an end portion of the outer conductor and having a hollow extension projecting in a generally axial direction beyond the end of the outer conductor. An electrically conductive contact ring is disposed within the hollow interior of the extension of the outer connector, and the ring is mounted for movement in a generally axial direction within and relative to the outer connector for engaging the end of the outer conductor. A generally cylindrical body member telescopes over the extension of the outer connector, and the body member and the outer connector have cooperating threaded surfaces for joining the two members.

  • Patent number: 5802710
    Abstract: A method of attaching a connector to a coaxial cable having concentric inner and outer conductors comprises the following steps. An end of the cable is prepared to expose a portion of the inner conductor and to expose a portion of the outer conductor. An insulative disc of the connector is installed onto the exposed portion of the inner conductor. An inner contact of the connector is installed onto the exposed portion of the inner conductor. A solder preform is installed onto the exposed portion of the outer conductor. A body member of the connector is installed over the solder preform onto the exposed portion of the outer conductor. To complete the cable assembly, the solder preform is melted to firmly attach the body member of the connector to the exposed portion of the outer conductor of the cable.
