A system, apparatus and method for thermal treatment of surface bonding optical is provided. An optical patch cord is surface bonded via thermal treatment with a tracer optical fiber which provides patch cord tracing in a bonding apparatus. During the process, the optical patch cord is also thermally treated to have the mechanical stress contained in its jacket relieved by rollers in the bonding apparatus to solve the patch cord shrink-back problem.

A machining system includes an application device that applies a photocurable resin to surfaces of a plurality of linear objects provided in a workpiece; a curing device that brings the linear objects, to which the photocurable resin has been applied by the application device, into close contact with each other in radial directions and that radiates light onto the photocurable resin, which has been applied to the linear objects brought into close contact, thus curing the photocurable resin; and a machining device that machines the workpiece, in which the plurality of linear objects have been bound together through the curing of the photocurable resin performed by the curing device.

A method of forming a plurality of individual heating cables sets includes creating at least a portion of a master cable set by coupling alternating sections of cold and hot cable section, each section of cold cable section having a length twice a model cold cable section length and each section of hot cable section having a length twice a model hot cable section length. A continuous metallic ground sheath is applied about substantially all of the master cable set and a continuous outer jacket is applied about the continuous metallic ground sheath. The master cable set is segmented at defined locations to create a plurality of individual heating cable sets having an overall length of the model hot cable section length plus the model cold cable section length.

A method of manufacturing a cable harness may comprise the steps of providing a plurality of cables, wherein each cable comprises a cable inner and a coating, wherein each cable inner comprises at least one conductor, locating at least a portion of each of the plurality of cables within a mould tool, heating the portions of each of the plurality of cables such that the coating of each cable consolidates to form a common harness with a solid cross section, wherein the cable inners are arranged within the common harness.

A self-bonding conductive wire and methods in which it is made and used. The wire comprises a conductor, an insulator, and a self-bonding outer coating. The self-bonding outer coating is a polyester polyether block copolymer. The insulator is an ethylene/tetrafluoroethylene copolymer, one or more layers of which may be used to insulate the conductor. The self-bonding capabilities of the wire may be activated by heating the wire, causing the outer coating to thermoplastically deform and fuse, allowing for the creation of self-supporting structures such as large bobbin-less coils. The use of the polyester polyether block copolymer for the self-bonding outer coating is superior to other materials, in which significant degradation of qualitative properties following self-bonding is observed, resulting in a superior self-bonding conductive wire.

Disclosed are a joining structure of different kinds of conductors, a joining method of different kinds of conductors, and a joint of power cables capable of improving joining reliability of a junction of the different kinds of conductors.

A wire bonding method includes: arranging a plurality of wires by inserting the wires with partially-exposed conductors into each groove of a wire arrangement tool provided with a plurality of grooves; and sandwiching the conductors of the plurality of wires arranged by the wire arrangement tool in a predetermined direction and bonding the conductors to each other. Further, in this wire bonding method, the sandwiching causes one arbitrary conductor among the conductors to receive a biasing force in a direction intersecting a direction of a force applied by the sandwiching, from another conductor in contact with the one arbitrary conductor among the conductors.

A small-diameter, continuously bonded cable and a method for manufacturing the same includes at least one longitudinally extending inner metallic component with a tie layer of an amended polymer material surrounding and bonded thereto in steps of heating and extruding. A longitudinally extending outer metallic component is radially spaced from the at least one inner metallic component and incased in a polymer material jacket layer in heating and extruding steps. The polymer materials insulate the metallic component for conducting electrical power and/or data signals.

The invention relates to a method for manufacturing a cable bundle. At least one provided first cable is completely coated circumferentially on an outer side of the insulating sheath of the first cable with a hot-melt adhesive. In a further step, the first cable is positioned so that it touches a provided second cable over at least a partial length of the cables. In a further step, at least one local adhesive connection is produced between the first cable and the second cable along a partial length of the cables by locally melting the hot-melt adhesive on the first cable.
