Patent number: 6484392Abstract: A process of weaaving metal conductor wires to form a metal woven shielding conductor layer over the outer surface of an insulated cable. The insulated cable is accompanied with at least one solder or tin wire. When the at least one solder or tin wire is immersed in a molten metal plating solution, it melts down hence generating a spatial margin between the insulated cable and the metal woven shielding conductor layer. This prevents the insulated cable from biting with its outer surface into the metal woven shielding conductor layer when it is thermally expanded in the molten metal plating solution. As the metal woven shielding conductor layer is impregnated deeply with the molten metal, there are hardly any generated gaps and undulation on the surface of the metal plating layer. Accordingly the suppression of reflection and attenuation of a transmission signal will be improved.Type: GrantFiled: February 28, 2000Date of Patent: November 26, 2002Assignee: Totoku Electric Co., Ltd.Inventors: Yoichi Okada, Yasushi Ooshima

Patent number: 6465732Abstract: A method and device for forming metal capacitor and integrated coaxial lines using energy transfer so as to form conductive links among conductors. Conductors are embedded within nonconductive layers, such that the conductors form a matrix of at least three levels. A source of energy is directed at the layers, such that at least one conductor is wholly shielded by at least one other conductor, and conductive paths form so that a conductor becomes shielded by the paths.

In one variation, links among differing layers are formed using more than one energy source or sequentially generated and directed pulses of energy.Type: GrantFiled: February 23, 2001Date of Patent: October 15, 2002Inventor: Michael Dueweke

The outer coat of the cable is placed around the exterior surface of the crimp body and a crimp ring is placed around the outer coat and the crimp body. The crimp ring is deformable and has an interior large enough to accommodate the crimp body and the outer coat. The crimp ring is deformable so that it can secure the outer coat between the crimp ring and the crimp body, with the groove and ridge arrangement of the crimp body further holding the outer coat in place.Type: GrantFiled: December 20, 1996Date of Patent: September 15, 1998Assignee: Siecor CorporationInventor: David T. Underwood

Patent number: 5802710Abstract: 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.Type: GrantFiled: October 24, 1996Date of Patent: September 8, 1998Assignee: Andrew CorporationInventors: Daniel E. Bufanda, John H. Dykstra, Jeff A. Ferdina

Patent number: 5787574Abstract: Drain wires of a shielded cable are exposed, untwisted, and expanded into the approximate shape of a sphere. Pressurized gas is applied to the expanded drain wires. Simultaneously, the cores are bent to bow upstream of the gas flow, whereas the drain wires, being relatively flexible, bend downstream thereof. Even if low pressure gas is used, the cores and the drain wires can be sufficiently separated. This permits the insertion of a tool or the like between the drain wires and the cores and, therefore, facilitates automation of the process.Type: GrantFiled: June 5, 1996Date of Patent: August 4, 1998Assignee: Sumitomo Wiring Systems, Ltd.Inventor: Kunihiko Watanabe

Patent number: 5781991Abstract: The invention relates to a method of implementing a shielded multiconductor cable to the tracks of a printed circuit. The conductors have end portions stripped and positioned. A first strip is put into place. Then each conductor core and a portion of its shielding are stripped. The stripped ends are put into position and then fixed to a second strip that is connected to the first strip by arms. The assembly is then fixed to the printed circuit by soldering the stripped ends to the conductor tracks and by soldering the stripped portions of shielding to the shielding connection track.Type: GrantFiled: October 7, 1996Date of Patent: July 21, 1998Assignee: Axon' Cable S.A.Inventor: Luc Papon

Patent number: 5770257Abstract: A method of altering a portion of the semiconductive layer of an electric power cable, to increase its resistance so as to render it electrically insulative. The semiconductive layer is loaded with carbon powder which forms chains to provide conductive pathways through the layer. By introducing an intercalant into the semiconductive layer, which causes the layer to swell, the conductive pathways are interrupted and the material is rendered insulative (>10.sup.4 .OMEGA.-cm). The intercalant may be a polymerizable material with a curing agent which is cured in situ, i.e., without removing the semiconductive layer from the cable. By this method, flashover to the semiconductive layer at a cable splice or termination may be prevented without requiring tedious removal of the exposed portion of the semiconductive layer. The method is usable with both strippable and coextruded semiconductive layers.Type: GrantFiled: August 1, 1996Date of Patent: June 23, 1998Assignee: Minnesota Mining and Manufacturing CompanyInventors: Gary A. Shreve, Nanayakkara Liyanage Don Somasiri, Justine Anne Mooney, Alan George Hulme-Lowe, Curtis Roy Guilbert

Patent number: 5768771Abstract: A method is disclosed for terminating the metallic shield of a high speed cable. The method includes the steps of providing a cable with an exposed portion of the metallic shield of the cable and a conductive terminating member having a plurality of positioning arms. Each arm is formable from an open position to a closed position. The metallic shields are soldered to a positioning arm while the arm is in its open position. Each arm is formed to its closed position to properly position the high speed cables.Type: GrantFiled: March 1, 1996Date of Patent: June 23, 1998Assignee: Molex IncorporatedInventors: Michael O'Sullivan, Daniel L. Dawiedczyk, Joseph W. Nelligan, Jr.

Patent number: 5718037Abstract: A portable, lightweight apparatus for moving a splice body with respect to a cable includes a first clamp member for engaging the cable, a second clamp member for engaging the splice body and a mechanism for moving the first clamp member and the second clamp member with respect to one another. The moving mechanism can include at least one gear rack extending between the first and second clamp members, and a pinion gear operably engageable with the rack. Sheathing can be provided for the rack between the first clamp member and the second clamp member to prevent entry of foreign material into teeth of the rack. In addition, an enclosure can be provided for housing a portion of the elongated rack extending outwardly beyond the first or second clamp members to prevent entry of foreign material into the teeth of the rack.Type: GrantFiled: May 9, 1996Date of Patent: February 17, 1998Inventor: Ted L.

Patent number: 5710393Abstract: A multiconductor cable (10) including a large number of coaxial conductor pairs (16), with the coaxial conductor pairs arranged in groups (14) each including several of the coaxial conductor pairs arranged in a required order as a modular array (18) with each of the conductor pairs of each array being held in a required position with respect to the others and supported with a portion of each central conductor (54) and each shield conductor (47) exposed at a predetermined position, for connection of the array to a corresponding array (28) of terminal pads (24, 26) on a circuit board (30) or the like. Each array includes support bodies (32, 34) of flexible dielectric sheet material adhesively attached to the coaxial conductor pairs to support them in the required positions. Apertures (70, 76) are defined in the sheet material to expose the conductors for simultaneous soldering to, or unsoldering from, the terminal pads (24, 26), without removal of the support bodies (32, 34) from the coaxial conductors.Type: GrantFiled: May 17, 1995Date of Patent: January 20, 1998Assignee: The Whitaker CorporationInventors: Daniel B.
