The present invention has a technical solution which achieves improvement of a withstanding voltage characteristic needed for diameter reduction of a cable in an insulating cable, thereby providing an insulating cable suitable for sliding. The technical problem may be solved by an insulating cable comprising a conductor and an insulator configured by a plurality of resin layers on the conductor, wherein the plurality of resin layers contain the same kind of fluorine resin, a difference in refractive index between a resin layer having the largest refractive index and a resin layer having the smallest refractive index among the plurality of resin layers is 0.03 or less, a layer thickness of an outermost resin layer of the insulator is 0.03 mm or less, and a deviation (coefficient of variation CV) in thickness of the insulator in a cross-section perpendicular to a longitudinal direction of the cable is 0.035 or less.

A coaxial cable includes a conductor, an electrically insulating member provided over a periphery of the conductor, a shielding layer composed of served shields formed by helically wrapping a plurality of metal wires around the electrically insulating member, and a sheath provided around the shielding layer. The electrically insulating member includes indentations on portions of its surface to be brought into contact with and mated to the metal wires respectively. The shielding layer includes portions in respective circumferential directions of the plurality of metal wires being brought into contact with the electrically insulating member are mated to the indentations, respectively, on the electrically insulating member, and adjacent ones of the metal wires in a circumferential direction of the shielding layer are in surface contact with each other.

A coaxial cable includes a coaxial wire in which an inner insulator, an outer conductor and a sheath are sequentially and coaxially provided around a center conductor, and a substrate having a surface on which a first contact pad and a second contact pad are arranged. The sheath is removed at one end portion of the coaxial wire by a predetermined length, so that the inner insulator and the outer conductor are exposed, and a tip end of the inner insulator is removed by a predetermined length, so that the center conductor is exposed. The exposed portion of the center conductor is soldered to the first contact pad with the exposed portion of the inner insulator being bent relative to the sheath, and the exposed portion of the outer conductor is soldered to the second contact pad with being bent in a direction different from the bending direction of the inner insulator. A part of the coaxial wire covered by the sheath is standing at an angle of 30° or greater relative to the surface of the substrate.

A cable unit is provided comprising: a jacket comprising at least one cable housing and at least one support housing; the or each cable housing having a tubular structure, extending in a longitudinal direction, each support housing in the plurality of support housings having a tubular structure, extending in the longitudinal direction, wherein the at least one support housing being disposed on one side of the at least one cable housing; and at least one support element retained within each support housing of the plurality of support housings, wherein the at least one support element retained within each support housing of the plurality of support housings comprises at least one portion that has an arcuate cross section in the width direction.

An apparatus that melts and monitors sleeves for installation onto shielded cables. The apparatus includes a heat source for melting the sleeve, cable supports for supporting the cable during the melting process, a sensor system that is configured to measure a dimension of the sleeve during melting, and a computer that is connected to receive sensor data from the sensor system and send heater control signals to the heat source. The computer is configured to receive dimensional data from the sensor system, monitor that dimensional data by performing a dimensional analysis, and then deactivate or remove the heat source in response to dimensional analysis results indicating that the sleeve is fully melted (in the case of a solder sleeve) or only fully shrunken (in the case of a dead end sleeve) onto the cable.

A shield trim is performed by tearing bunched shield strands circumferentially along a circular edge. The apparatus includes a pair of aligned metal plates that have been drilled through multiple times such that holes of varying diameters pass through both plates. A cable gripper on the entry side of the device clamps the cable in place. A shield gripper on the rear side of the device closes over the exposed shielding of the cable, and the two plates are pushed together. The shield gripper travels with the rear plate, pushing the shield over the wires and causing the shield to bunch between the two plates. With the two plates pushed together, both grippers open and the cable is pulled free from the device. This pull forces a stress concentration which tears the shield strands across the sharp edge of the hole, producing a uniformly trimmed shield.
