An F-connector for a coaxial cable comprises a front insulator, a back insulator, a connecting lead, and a locking ring. The connecting lead has an interior portion and an exterior portion. The interior portion is configured with a pair of side wall portions which are parallel to each other, and which together with a bottom portion form a U-shaped channel. The side wall portions each comprise a curved portion that are configured to grip the center conductor of the coaxial cable so as to withstand a certain level of withdrawal force, and such that the F-connector exhibits a desired impedance of 75 Ohms. The connecting lead engages with the front insulator and the back insulator such that the components are held in position within a connector body.

Axially compressible, high bandwidth F-connectors designed for conventional installation hand tools for interconnection with coaxial cable. Each connector has a rigid nut that is axially and rotatably secured to a molded plastic, tubular body. A rigid, conductive post coaxially extends through the connector, linking the nut and body. A post barbed end penetrates the cable within the connector. The body has a tubular shank with an obstruction-free surface and an integral stop ring. A tubular, metallic end cap is slidably fitted to the body shank, and thereafter forcibly compressed lengthwise, with travel limited by the stop ring. No detented structure is formed on the body, and the end cap can irreversibly assume any position, being held by end cap teeth. A tactile system comprising convex projections on the stop ring complemented by a resilient O-ring on the end cap helps installers determine correct placement through the sense of touch.

A jumper sleeve for connecting and disconnecting a male F connector to and from a female F connector includes a wrench portion and a grip portion. The wrench portion has a leading end, a trailing end, and a hollow main body located between the leading end and the trailing end. The main body of the wrench portion internally has a hexagonally shaped portion corresponding to a shaped outer surface of a rotatable connecting ring of the male F connector. The grip portion has a rear end and a front end connected to the trailing end of the wrench portion, and has a plurality of circumferentially spaced externally convex sections, each of which has a radially inward key formed near the rear end thereof. The jumper sleeve provides greater mechanical advantage to produce sufficient torsion force, enabling easy installation and removal of the male F connector.

Barrel connectors, a right angled adaptor and a single ended fitting include at least one axially displaceable traveling sleeve for insuring electrical continuity with coaxial connector, nominally an F-connector. Each barrel connector described comprises a rigid, metallic hollow body housing an internal contact tube. At least one coiled spring is retained within the body. At least one elongated, tubular traveling sleeve is coaxially disposed within each body end and normally biased outwardly by the springs. The metallic traveling sleeves comprise an elongated shank that contacts the spring, and a head that seats against the connector body ends during installation. Catches or rings defined upon or mounted to travelling sleeve shanks are received within suitable grooves for anchoring the traveling sleeves while facilitating limited axial displacements. The traveling sleeves, and the contact tube therewithin, normally are biased outwardly so that even limited torquing of an F-connector will establish a ground path.

A driver tool for coaxial cable connectors is provided. The tool can drive both F-series coaxial cable connectors having a hex sleeve and BNC coaxial cable connectors having a bayonet sleeve. The driver tool has a socket which includes a first drive surface in the form of a plurality of flat segments formed on the socket and engageable in rotationally interlocking relation with the hex sleeve of an F connector. The socket also has a second drive surface in the form of a collar sized for frictional engagement in rotationally interlocking relation with the bayonet sleeve of a BNC connector. A longitudinal slot in the sleeve accommodates a coaxial cable. A handle and shaft connect to the socket.

A Cable Wrench that guides, connects and disconnects an F-Connector male end attached to a coaxial cable, to an F-Connector female connection on a TV, VCR, computer or any other device that uses coaxial cable or a cable splitter. This invention prevents the coaxial cable from becoming disengaged, or from slipping out of the cable wrench by using a curved slot that runs the entire axial length of the tool. The wrench provides a large cut away section at the wrench end to allow better visibility while operating the tool and a section adjacent to and behind the wrench portion that is wider in order to allow use of the tool with crimped or large connectors.

Axially compressible, F-connectors for conventional installation tools for interconnection with coaxial cable include adaptations for establishing electrical continuity despite inadequate nut tightening. Each connector has a rigid nut, a post penetrating the nut, a tubular body, and an end cap. The conductive post coaxially extends through the connector, linking the nut and body. A post end penetrates the coaxial cable. The connector may have a circumferential groove defined in the end cap mounting an annular D-ring which tensions contact between the post and nut. The connector may comprise a continuity coil seated within a post groove in spring-loaded contact with the nut and the post for promoting continuity. The connector may comprise a pressure spring and an O-ring seated within a post groove in spring-loaded contact with the nut for promoting continuity.

A tool includes a first and a second socket wrench pivotally turnably connected to two ends of a link. Each of the first and second socket wrenches includes a wrench portion and a circular end portion having an axial slot extended through them. The wrench portion of the first socket wrench is internally formed of a hexagonally shaped portion for fitting around a hexagonally-shaped outer surface of a connecting ring of a male F connector to tighten or loosen the connecting ring to or from a female F connector, and the wrench portion of the second socket wrench is internally formed of a constant-torque shaped portion for fitting around the hexagonally-shaped outer surface of the connecting ring to prevent the tool from applying an excessive torque on the connecting ring when turning the same. The tool can be used without being hindered by bent or closely arranged cables.
