  • Patent number: 8678858
    Abstract: A coaxial connector is combined with an inner conductor interconnection cap, for interconnection with a coaxial cable. The interconnection cap is provided with a bore adapted to seat upon and circumferentially contact an outer diameter of the inner contact and an outer diameter of the inner conductor. The interconnection cap extends along the inner contact to cover at least a contact portion at a cable end of the inner contact to enclose an interconnection between the inner conductor and the inner contact. Sealant may be applied to the interconnection to improve seal performance and the dimensions and materials of the interconnection cap may be adjusted to modify characteristic impedance for return loss optimization with respect to specific coaxial cables.

  • Patent number: 8454383
    Abstract: A self-gauging electrical connector for coaxial cables with outer conductors of varied diameters is provided with a clamp ring coupled to a connector body with a bore. A mechanical grip and an electrical contact are retained within the bore. The mechanical grip and the electrical contact engage the outer conductor upon insertion of the outer conductor into the bore. The mechanical grip is displaced radially proportional to an outer diameter of the outer conductor. The electrical contact is displaced radial proportional to the radial displacement of the mechanical grip.

  • Patent number: 8393919
    Abstract: A coaxial connector provided with an increasing diameter compression sidewalk A grip ring is seated within the coupling body bore and is provided with a plurality of coupling spring fingers extending from the grip ring. An inner diameter of the coupling spring fingers has a grip surface and an inward projecting cable stop is provided at a connector end of the grip ring. The connector body and the coupling body are coupled together via threads, the grip ring dimensioned for axial advancement of the coupling body along the threads to drive the coupling spring fingers against the compression sidewall to exert a compression force radially inward upon the outer diameter of the outer conductor seated in the coupling body bore abutting the cable stop.

  • Publication number: 20120184135
    Abstract: A coaxial connector is provided with a connector body coupled to a connector coupling body. A slip ring is provided within a bore of the connector coupling body. An outer conductor groove of the connector body is open to a cable end of the connector body. A contact surface is provided on an inner sidewall of the outer conductor groove. A spring contact is provided between the slip ring and the connector body and a stabilizing assembly is coupled to a cable end of the connector coupling body. The axial advance of the connector coupling body towards the connector body drives the slip ring against the coil spring to clamp a leading edge of the outer conductor inserted into the outer conductor groove against the contact surface. The stabilizing assembly grips a jacket of the coaxial cable, stabilizing the interconnection. Methods of manufacture and interconnection are also disclosed.

  • Patent number: 8220158
    Abstract: A cable end preparation tool is for a coaxial cable and has a C-shaped body with an opening therein to receive the coaxial cable and a side defining a saw guide to receive a saw blade thereagainst. The C-shaped body includes a gripping rib to fit in a valley of a corrugated outer conductor when the coaxial cable is in the opening. At least one stabilizing rib is adjacent the gripping rib to receive a crest of the corrugated outer conductor thereagainst when the coaxial cable is in the opening. The C-shaped body also includes a rotation guide feature receives the inner conductor. A cutting blade extends outwardly from the C-shaped body for removing a portion of a dielectric between the inner conductor and the corrugated outer conductor as the C-shaped body is rotated about the rotation guide feature.

  • Publication number: 20120129388
    Abstract: A coaxial connector for interconnection with a coaxial cable with a solid outer conductor by laser welding is provided with a monolithic connector body with a bore. A sidewall of the bore is provided with an inward annular projection angled toward a cable end of the bore. A sidewall of the inward annular projection and the sidewall of the bore form an annular laser groove open to a cable end of the bore. The annular laser groove is dimensioned with a taper at a connector end of the laser groove less than a thickness of a leading end of the outer conductor. The taper provides an annular material chamber between the leading end of the outer conductor, when seated in the laser groove, and the connector end of the laser groove.

  • Patent number: 8136234
    Abstract: A cable end preparation tool is for a coaxial cable having an inner conductor, an outer conductor, and a dielectric therebetween. The cable end preparation tool includes a body and a blade carried by the body for removing a portion of the dielectric between the inner conductor and the outer conductor when the body is rotated about the coaxial cable. A first projection is carried by the body and has a predetermined shape for flaring an end portion of the outer conductor when the body is rotated relative to the coaxial cable. A second projection is movable with respect to the body between an outer conductor engaging position and a disengaged position, the second projection for corrugating the flared end portion of the outer conductor when in the outer conductor engaging position and the body is rotated relative to the coaxial cable.
