  • Patent number: 6281442
    Abstract: A cable fitting for the protection of cable connections in a medium voltage range has a shrinkable inner insulating sleeve with a field controlling or shielding element as a coating on an inner surface, a shrinkable outer protective sleeve and a protective sleeve that completely covers the arrangement. A combination of the field controlling or shielding element with the shrinkable inner insulating sleeve reduces the number of steps in forming the cable fitting on the cable connection.

  • Patent number: 6265663
    Abstract: In a terminal for a high-voltage electric cable the electric cable is terminated at a predetermined height from its entry into the terminal and the electric connection between the cable conductor the overhead line is obtained by a rigid conductor element. The rigid conductor element, preferably a copper pipe, is provided with an elastomeric ribbed coating and is supported by an insulating base preferably made of an epoxy resin. An assembly constructed from an epoxy resin base and a rigid conductor element brings the electric field at the surface to a value consistent with the dielectric strength of the air and is long enough to form an insulation path suited for the installation environment.

  • Patent number: 6262373
    Abstract: A strain relief bracket for use in conventional and modular furniture applications guards against excessive bending of copper and fiber optic cable. The device is a substantially rigid durable bracket that has an adhesive surface for adhesion to the interior of a furniture wall. The device is bi-planar, having a first section in a first plane, a raised flange section in a second plane, and a second section connecting the first section and raised flange section. A flange at the end of the first section secures the bracket to the edge of an opening in the furniture wall. Cables are secured to the bracket by cable ties that extend through holes provided on the raised flange section. The bi-planar arrangement of the bracket minimizes the bend radius of the cables and thereby strain relieves the cable, adapters, and connectors in the wall.

  • Patent number: 6239388
    Abstract: A splicing device is provided for being fastened to one end of a cable wherein fibers/wires in the cable are connectable to the device. Further, the cable sheathing is brased to the device by a tightening procedure. The connection of the device to the cable is made under a controlled environmental condition, for instance, in a factory, during transport to the place of cable laying, or the like. The device is designed in a watertight design wherein the cable is allowed to be lowered down into water without further measures needing to be taken. The device further can be opened, in which connections for the measuring equipment are accessible. Measuring of the cable after that can be performed. The device is usable, for instance, in the laying of a submarine cable from cable ships. The device includes a splicing part and a measurement connection part. In the splicing part of the device, the fibers/wires of the cable are connected.

  • Patent number: 6238777
    Abstract: A printed-circuit board according to the present invention includes: a plurality of insulating layers; a plurality of conductive patterns formed in each insulating layer; and a plurality of closed and curved patterns each formed around the conductive patterns in each insulating layer, and each formed by a material having a coefficient of linear thermal expansion smaller than that of the insulating layer. In this case, each closed and curved pattern is made of copper and formed of same material as that of each conductive pattern. Further, when the coefficient of linear thermal expansion of each insulating layer is &agr;1, when the coefficient of linear thermal expansion of each conductive layer is &agr;2, and when the coefficient of linear thermal expansion of each closed and curved pattern is &agr;3, the following condition, i.e., &agr;1>&agr;2≧&agr;3, is satisfied.

  • Patent number: 6227881
    Abstract: A cable shielding interconnect is provided that includes a star-anvil having a base and a plurality of radially projecting arms that are circumferentially spaced from one another so as to define a plurality of cable support saddles between the arms. At least two shielded cables, each including a dielectric jacket and at least one shielding member, are positioned within respective ones of the saddles, with each shielding member being electrically and mechanically accessible. A ferrule is positioned in crimped coaxial relation to the star-anvil and the at least two shielded cables are positioned in corresponding ones of the saddles so as to position each of the electrically and mechanically accessible shielding members in electrical communication with the star-anvil. The invention also provides for selective electrical interconnection of shields. A method is also provided for interconnecting cable shielding to a common electrical potential.

  • Patent number: 6171669
    Abstract: A storable tubular element for covering an electric cable joint which includes a rigid tubular support with a three layer sleeve having an unstretched bore of a size less than the external diameter of the support mounted on the tubular support in radially stretched condition. The element is usable for a group of cables having several different diameters and the properties and thicknesses of the layers are selected so that with storage on the support, the layers do not tear and so that when the sleeve is applied to a joint, the sleeve will apply the desired pressure to the cable even though it has a temporary residual deformation and does not immediately tend to return to its initial unstretched state.
