A magnetic data cable includes a cable body and data connectors. The data connectors are respectively connected to two ends of the cable body. The cable body includes a cable core and a wrapping material layer wrapped around the cable core. At least one layer of the wrapping material layer is a magnetic material layer. When the magnetic data cable is wound into coils, each two adjacent coils arranged from top to bottom or each two adjacent coils arranged from left to right are magnetically attracted to each other by the magnetic material layer. Since the magnetic material layer is integrally distributed in the wrapping material layer, so the cable body 100is magnetic and it is easy and simple to adjust a diameter of the coils by winding.

A laminated cable includes a metal laminate surrounding a cable core having first and second ends. Solder is applied adjacent the ends of the laminate, and is heated and subsequently cooled to form a metal seal. The solder can be melted in a plastic jacketing extruder as the extruder applies a plastic jacket over the metal laminate.

摘要:
The invention relates to an electrical cable (2) comprising a cable bundle (4) formed by at least two single wires (6), each single wire comprising a conductor (8) surrounded by insulation (10). An adhesive layer (12) is applied to at least one, preferably to all single wires (6), surrounding the insulator (10) in a ring-like manner, via which adhesive layer the single wires (6) are adhered to one another. The cable bundle (4) does not also comprise a cable sheath surrounding the cable bundle (4). In particular, the adhesive layer is formed by a reactive coating that is cured after activation so that a thermally stable connection can be achieved. In particular, the cable bundle is formed by single wires (6) that are twisted with one another, and which are used, in particular, as a data line. This structure, with the adhesive layer (12), removes the need for a cable sheath so that a more compact structure can be achieved. At the same time, the form of the cable bundle (4), in particular the lay length, is fixed, having a positive effect on the transmission characteristics for a data line.

The present invention aims to provide an electric wire that is capable of being produced by extrusion molding and is excellent in heat resistance and crack resistance. The present invention relates to a heat-resistant electric wire including a core wire and a coating that covers the core wire. The coating is formed from a modified fluorine-containing copolymer that is obtained by irradiating a copolymer with radiation at an exposure of 250 kGy or lower at a temperature of not higher than the melting point of the copolymer. The copolymer is at least one copolymer selected from the group consisting of a copolymer including a tetrafluoroethylene unit and a perfluoro(alkyl vinyl ether) unit and a copolymer including a tetrafluoroethylene unit and a hexafluoropropylene unit.
