  • Patent number: 4768287
    Abstract: A plug connector is joined to a shielded flat ribbon cable including a plurality of insulated leads disposed laterally adjacent to one another, the cable further including an electrically conducting shielding enveloping the leads. The shielding is severed along the lateral edges of the cable to form a first shielding layer on one side of the cable, the first layer being additionally severed along a zone extending substantially transversely to the leads and peeled back to enable insertion of the plug connector. The second layer is separated from the insulated leads and a first portion of the plug connector is inserted from the side between the separated second layer and the insulated leads. A second portion of the plug connector is disposed in juxtaposition to the insulated leads on the one side of the cable upon completion of the step of peeling. The first portion and the second portion of the plug connector are then pressed against the cable.

    Abstract: An optical fibre ribbon structure suitable for use in an optical cable or other application where there is a risk that optical fibres will be subjected to a tensile force comprises a plurality of optical fibres and flexible reinforcing elements of resilient material arranged side by side and embedded in an elongate plastics body. Each resilient reinforcing element is set in such a form that the ribbon structure follows a path of smoothly curved undulations whose axes of curvature lie parallel to one another and normal to the longitudinal axis of the ribbon structure. When the undulting ribbon stucture is subjected to a tensile force, the ribbon structure straightens in a lengthwise direction against the action of the resilient reinforcing elements thereby reducing the tensile force otherwise applied to the optical fibres. When the tensile force is removed, the ribbon structure returns towards its original undulating form.

  • Patent number: 4596897
    Abstract: An electrical shielding tape comprises a polyester backing layer, and a metallic layer having an adhesive on the exposed surface thereof, the adhesive being disposed in an interrupted layer which defines both exposed open patches, or contact pads, and coated bonding areas thereon. The tape is constructed for use in a shielded cable of the type having at least one conductor wire and an uninsulated drain wire, wherein the tape is wrapped around the conductor and drain wires with the metallic surface of the tape facing inwardly and with the tape adhesively secured to the conductor and drain wires by means of the adhesive on the metallic surface thereof. Effective electrical contact between the tape and the drain wire is achieved in the open patches, or contact pads, which contact the drain wire, and therefore the tape can be grounded to achieve the desired shielding effects simply by connecting the drain wire to a ground terminal.

  • Patent number: 4572926
    Abstract: An armored electrical cable which is especially useful in oil wells and provides resistance to corrosion, explosive decompression and transverse compressive forces. The cable comprises an insulated conductor, a barrier layer enclosing the insulation, a filler layer enclosing the barrier layer, and a square compression-resistant layer enclosing the filler layer. The barrier layer is a lead sheath having a closed cross section with an exterior including four right angle corners oriented in a square and four convex areas, each interconnecting a pair of adjacent right angle corners. The filler layer comprises a thermosetting tape, an open-mesh fabric tape, and a polymeric tape of low frictional coefficient.

  • Patent number: 4567320
    Abstract: A reinforced insulated electrical cable and a method of forming the cable, which is especially useful in oil wells. The reinforcement comprises a thin tape of thermosetting material imbedded with an open-mesh fabric, the tape being spirally wrapped directly around the cable's insulation. The tape is wrapped in unvulcanized form and is then vulcanized in place over the insulation. The layer of open-mesh fabric is spaced from the outer surface of the insulation so that, during vulcanization, the insulation can radially outwardly expand without contacting and thus deforming the fabric, and at the same time the insulation can push part of the thermosetting material through the spaces in the fabric.

  • Patent number: 4564723
    Abstract: A shielded ribbon cable is formed either by trimming a conventional ribbon cable to expose one or both edge conductors, and coating the cable by painting it with a conductive paint or covering it with an extruded conductive plastic layer, or by forming a ribbon cable of individually-coated wires, one or both edge conductors having a conductive coating, and subsequently painting it with a conductive paint or covering it with an extruded conductive plastic layer. One or both edge conductors thus serve as drain wires for the shield formed by the external covering of conductive paint or conductive extruded plastic.

  • Patent number: 4551576
    Abstract: A flat embedded-shield multiconductor signal transmission cable includes an embedded conformal shield interposed between adjacent conductors to significantly reduce cross-talk by as much as several orders of magnitude over conventional techniques. The shield is forced to a shape in which it is interposed between adjacent conductors by pinch rolling a sandwich of the conductors, insulation and shield between heated rollers, in which the top and bottom sets of conductors are forced inwardly to lie one beside the other with the shield in between. Uniform termination impedance is achieved because the embedded shield is protected during cable stripping. In an alternative embodiment, external shielding may be utilized to completely circumferentially surround the conductors. For improved pitch control, both heated pinch rollers are identical and are provided with resilient surfaces.

  • Patent number: 4548661
    Abstract: A multiconductor flat cable incorporates an approximately right angle turn in its conductor runs. The right angle turn is provided by first securing the conductor runs in a desired spacing through a first lamination of insulation cover and base sheets while leaving portions of the conductor runs exposed through a window in the first lamination. The first lamination is then severed at the lateral edges of the window so that an end portion of the first lamination may be moved ninety degrees relative to a remaining body portion thereto. The right angle turn is then secured by forming a second lamination with cover and base layers so as to overlap the first lamination and the turn in the conductor runs.

  • Patent number: 4538024
    Abstract: Apparatus for manufacturing ribbon cable having a plurality of filamentous elements comprises a wheel having a circumferential surface interrupted by a plurality of parallel grooves in which the elements are seated over a common arc. Elements are supplied tangentially toward the wheel as the wheel is rotated and plastic is extruded at a point on the common arc to form a ribbon cable with elements exposed where they lay in the grooves. Elements are entrapped in cable by plastic bridges formed in lateral channels or recesses which interrupt the grooves and permit plastic to flow around elements, by fiber mat which the plastic impregnates, by melt-bonding to plastic insulated wire, by adhesive, or by nearly complete entrapment of elements resulting from a shallow groove profile. An additional layer of plastic may be extruded onto the cable so produced to yield a conventional fully insulated ribbon cable, or for some cable profiles the cable may be mated to like cable for a close centerline spacing of elements.
