  • Patent number: 6175080
    Abstract: A strain relief and pull-strength termination with controlled impedance for a transmission cable has a carrier with a flat portion for accepting one end of the cable and tabs extending from the flat portion. The cable is secured to the flat portion via soldering of the shielding conductor to the flat portion or by glueing. A housing having tabs formed therein receives the carrier. The tabs in the housing are bent down to engage the carrier tabs to provide strain relief and cable-pull strength.

    Abstract: The present invention provides a sealed cable-terminating structure in which a braided-shielding member is fastened to supporting members with high strength, and in which an optimum shielding effect can be ensured, and a simple termination method for realizing such a terminating structure. An end portion of a shielding member (50) on a clamped side has a folded-back section (55a), which is formed by being turned inward. A portion of the folded-back section (55a) is fastened by clamping to socket (20) by a clamping member (31), and it is extended by a prescribed length in a direction away from the fastened portion.

  • Patent number: 6085416
    Abstract: A wire shielding method which achieves electromagnetic shielding and reduces the number of component parts so as to enhance the efficiency of an assembling operation. In the wire shield structure, wires are covered with a shield member formed by laminating a metal foil layer and insulating layer together. The wires are led out of the shield member and connected to desired equipment. An extension portion of the shield member is folded, with the metal foil layer disposed at the inner side to form a lead wire portion. A distal portion of the lead wire portion is folded back with the metal foil layer exposed to form an earth terminal for grounding purposes. Therefore, without the use of a separate lead wire, the shielding effect can be enhanced and the number of component parts can be reduced.

  • Patent number: 5281762
    Abstract: A grounding connection and method for use with multi-wire cable (10) of a type having a plurality of individual cables (12) arranged in side-by-side relationship with each cable including an outer insulation sheath (14) extending around a relatively fragile, thin ground shield (16) in turn extended around a dielectric sleeve (18) carrying a fine signal wire (20) includes the provision of a body (22) of conductive plastic molded or cast around the exposed shield to provide a permanent electrical interconnection and commoning of the shield (16) of the multiple cables. A grounding bus (26) is used with the body (22) to interconnect ground circuits to external ground paths of circuit boards or the like. An alternative embodiment includes plastic material having sufficient strength to form fasteners (50) or latches (54) extending the use of the body (22). A thin wall plastic housing (60) may be used as an alternative definition of a cavity into which the material is poured to form the body (22).

  • Patent number: 5237129
    Abstract: A shielded cable passes through a kickpipe in a structural plate member, h as the deck of a ship. The kickpipe has a necked-down portion designed to receive the cable at a point where the cable shielding has been exposed. Axially compressible radially expandable iris, or toroidal, springs are engaged by an adapter nut threadably received inside the kickpipe to create a low impedance ground connection from the cable shielding to the deck. The adapter nut has a cavity for receiving a packing material and a gland nut is received in the adapter cavity to seal the ground connection from the environment.

  • Patent number: 5164545
    Abstract: A grounding connector for interconnecting a ground wire with a pipe in a one-piece stamped and formed member (10) which includes an outer section having diverging walls (14,16) extending from a base section (12) to form a V-shaped channel (18), upper sections (20,22) of the walls (termed outer walls) being crimpable toward each other and locked in a vertical orientation when applied to the pipe (70) and wire (68). An inner section (30) extends integrally from the top (24) of one outer wall (20) and is latchable to the top (24) of the other outer wall (22), and includes a pair of inner walls (36,40) joined by a central arcuate portion (38) crossing the top of the U-shaped channel (18).

  • Patent number: 5151560
    Abstract: A grounding connector for interconnecting a pair of uninsulated conductors such as wires includes an outer body member having diverging tabs extending from upper extents of vertical walls of a U-shaped channel, the tabs being crimpable toward each other when applied to the wires. An inner body member includes a base section crossing the top of the U-shaped channel and diverging inner tabs extending along the inside surfaces of the outer body member to assured stops at the ends of the outer tabs. When the outer tabs are crimped to a vertical orientation, the inner tabs are also crimped to a vertical orientation and urge the base section against the wires in the U-shaped channel. The inner body member presses the wires against upper and lower surfaces of a conductive insert so that arrays of penetrating spikes along the insert surfaces break through corrosion of the wires and assuredly electrically interconnect the wires.

  • Patent number: 5028742
    Abstract: A device for connecting the grounding shield layer of a cable in a splice connection. A flat strap, such as a mesh of metallic wires, is wrapped at least 270.degree. around the shield layer. The ends of the strap or braid are folded over, forming two generally parallel tails. The central portion of the braid is secured to the shield with a constant force spring, and the free ends of the braid are fastened to the shield layer on the opposite side of the splice. A second braid may be used in a similar manner to bridge the connection across the splice. By providing two tails emanating from a single braid, current surges in the shield layer are divided along two current paths, reducing current density and minimizing failures in the cable shield connection.

  • Patent number: 5015805
    Abstract: In providing a coaxial cable having reinforcing strands with a Kellems grip onnector, a length of the outer sheath is initially removed to expose the core, reinforcing strands and metallic braid. The exposed strands are formed into a multiplicity of bundles which are initially folded away from the end of the cable, and a metallic washer is placed over the exposed core and conductively bonded to the metallic braid. A Kellems grip connector having a connector element and a cylindrical mesh compression sleeve is inserted onto the core, and the sleeve extends over the washer and the strands. The washer is conductively connected to the connector of the Kellems grip connector which is spaced closely thereto. The bundles of strands are pulled outwardly through peripherally spaced openings in the mesh sleeve and looped about the intersections of the wires of the sleeve adjacent the connector.
