  • Patent number: 6095828
    Abstract: An electrical coupling has a ring through which extend multiple screened wires. The ring has several longitudinally-extending integral splines projecting from its outer surface from which project a curved, circumferentially-extending spring arm on each side. The wires extend through the ring and their screening sleeves are folded over an end, contact surface of the ring and back along its outside, being retained under the spring arms. A metal cap fits over one end of the ring holding the sleeves against the contact surface and protecting them around the outside of the ring. The cap is held on the ring by a collar, which extends around its outside and screws onto a body member at the opposite end of the ring.

  • Patent number: 5997350
    Abstract: A compression type coaxial cable F-connector includes a conventional coupling nut and tubular post. A cylindrical body member is secured to the tubular post and includes a sleeve for receiving the jacket of the coaxial cable. A circular relief in the sleeve allows the end of such sleeve to be deformed inwardly toward the cable jacket. A compression ring is mounted over the outer wall of the sleeve of the cylindrical body member and includes a tapered inner bore which forces the end of the sleeve inwardly against the cable jacket as the compression ring is advanced axially over the cylindrical body member. As the end of the sleeve is deformed inwardly, it extends just behind a circular barb formed about the tubular post to pinch the cable jacket therebetween. The compression ring can be manufactured as a separate component, or the compression ring can initially be integral with the sleeve of the cylindrical body member and attached thereto by a frangible connection.

  • Patent number: 5321207
    Abstract: A coaxial conductor includes a BNC coax connector, a coaxial cable and a sleeve. The coaxial cable has a center conductor, a braided outer conductor, a dielectric which separates the center conductor from the braided outer conductor and an insulating jacket which is provided around the braided outer conductor. One end of the insulating jacket is stripped so as to expose a portion of the braided outer conductor. The exposed portion of the braided outer conductor is pulled over the insulating jacket so as to expose a portion of the dielectric. The exposed portion of the dielectric is stripped so as to expose a portion of the center conductor which is extended into a tubular inner conductive portion of the coax connector so as to connect electrically therewith. The sleeve has a front end with a wide tubular part which engages a tubular outer conductive portion of the coax connector and a rear end with a narrow tubular part.

  • Patent number: 5293177
    Abstract: An antenna connector comprises a first housing for housing an end of a coaxial cable, first and second contact to be connected to a core wire and a shield wire, respectively, of the coaxial cable housed in the first housing, a second housing for housing the first housing, and a pair of conductive feeding metal plates. The feeding metal plates are arranged on and secured to a conductive antenna pattern formed on an insulative substrate and each of them has a first holder for receiving and holding the second housing and a second holder for receiving and holding the first and second contacts. When the first housing is housed in the second housing, the first and second contacts are engaged with and held by the second holder to plugably connect the coaxial cable to the antenna without disturbing an impedance matching and with a sufficient mechanical strength.

  • Patent number: 5273458
    Abstract: A method for crimping a terminal (30) to an end of an inner conductor (20) of a coaxial cable (10) so that the resulting crimp joint (22) is precisely located a selected distance rearwardly from a mating point of the contact section (32) with a complementary contact section of a mating terminal affixed to an other coaxial cable. The terminal includes an intermediate section (42) of selected length, reduced diameter and location between the body section (34) and the crimp joint (24), such that, in cooperation with a smaller diameter forward portion (218) of the bore of the connector outer shell (210) coextending therealong, a region of deliberate impedance mismatch results compensating for other mismatches of the coaxial connection for minimized overall mismatch.

  • Patent number: 5217393
    Abstract: A crimp type F-Connector wherein the crimp required for easy installation reduced while affording reliable cable retention. A wide range of cable sizes are accommodated by one connector which is configured to provide adequate sealing and mechanical strength in the connector while facilitating optimized radial deformation for providing reliable retention and a reliable mechanical and electrical interface with the coaxial cable upon which it is crimped. The connector includes a crimping portion including a sleeve that has a plurality of ribs or external annular protrusions which are dimensioned to enhance rigidity and mechanical strength. The ribs are of equal diameters when uncrimped and are "flat" crimped to maximize the cable area against which crimp forces are applied. An innermost rib is proximate to a support wall and separated by an exaggerated spacing to reduce crimp forces experienced when installing the connector onto the cable.

  • Patent number: 5207596
    Abstract: An improved coaxial cable connector and method for attaching the same to a coaxial cable is disclosed. The improved cable connector comprises a center conductor pin, which may be hollow or solid, for providing electrical conductivity for the center wire, an outer conductor shell, which is concentric to the center pin, for providing electrical conductivity for the shielding wire, and an annular dielectric, such as a phenolic washer, mounted to the center conductor pin for insulating the conductor pin from the outer conductor shell. The improvement lies in the use of an inner wire receptor having a funnel portion for receiving the center wire and a holding portion, which is crimped, for mechanically and electrically securing the center wire.

  • Patent number: 5154637
    Abstract: The terminations provide a means for connecting coaxial power cables carrying tens to hundreds of kiloamperes of pulsed current to electrical devices without producing arcing or melting during operation; and also provide mechanical support at cable ends where otherwise unsupported ends would be damaged due to magnetic force acting on current carrying members. To avoid contact arcing (1) the contact supplies mechanical support to the cable at the termination, to prevent magnetic forces from moving the conductor in any direction which would loosen the contact; (2) the connector is installed with sufficient force to meet the a given resistance criterion, and the force is maintained during the expected life of the cable and termination; (3) a smooth, well-defined surface is provided at the surface of the connector where it interfaces with the mating system contact.
