A connector includes an insulator, a plurality of pairs of terminals provided on the insulator, and a resistance element. The plurality of pairs of terminals include at least one pair of cable terminals electrically connected with a cable and at least one pair of vacant terminals that are unused. The resistance element is electrically connected between each pair of vacant terminals.

An electrical cable splice includes a housing having a channel configured to hold a first signal conductor of a first electrical cable therein. The channel is configured to hold a second signal conductor of a second electrical cable therein in electrical engagement with the first signal conductor such that the first and second signal conductors are electrically interconnected. The second electrical cable has a greater diameter than the first electrical cable. A ground shield external to the housing such that the ground shield extends at least partially around the first and second signal conductors. The ground shield is electrically connected to electrical ground conductors of the first and second electrical cables.

A hybrid optical and electrical connection system includes a connectorized pigtail and a closure. The connectorized pigtail includes: a) a stub cable including a jacket containing at least one optical fiber and at least two electrical conductors, the stub cable having opposite first and second ends; and b) a hybrid optical and electrical connector that is factory terminated at the first end of the stub cable. The closure mounts at the second end of the stub cable for enclosing optical and electrical connections between the second end of the stub cable and a field cable.

A wiring member includes: at least one first cover wire; at least one second cover wire; and a first sheet to which at least the first cover wire is fixed, wherein a first hole is formed in the first sheet, and a connection part where a core wire of the first cover wire and a core wire of the second cover wire are connected is located in a region where the first hole is formed.

A method for joining a cable to a connector includes: providing an electrically conductive fusible conductor joining material which has a lower melting point than that of at least one inner conductor of the cable and/or at least one contact of the connector; bringing an end of the connector to an end of the cable such that at least one inner conductor of the cable and at least one contact of the connector are opposite one another and the fusible conductor joining material is present in between; and heating the cable and/or the connector from the outside such that the heat penetrates into an interior of the at least one heated cable or the connector so the fusible conductor joining material melts and electrically connects the at least one inner conductor of the cable and the contact of the connector to one another.

A method for joining a first cable to a second cable that each include at least one electrically conductive inner conductor, an outer sheath which at least partially surrounds the at least one inner conductor, and an insulation material which is arranged at least partially between the at least one inner conductor and the outer sheath. The method includes: bringing an end of each cable together such that at least one inner conductor of the cables are opposite one another and a fusible conductor joining material having a lower melting point than the at least one inner conductor is present in between; and heating at least one of the cables from the outside such that the heat penetrates into an interior of the at least one heated cable so the fusible conductor joining material melts and electrically connects the at least one inner conductor of the cables to one another.

A heating assembly configured to receive a power cable for restoring an insulation system of the power cable, the heating assembly including: a central pressurisation and heating structure, and a first and second lateral structure provided at a respective axial end of the central pressurisation and heating structure, the first and second lateral structure each having at least a 20 cm long axially extending section primarily made of a material at most having a conductivity of the order of 1000 S/m at 20° C.

A choke comprising a core and a first power conductor, wherein the first power conductor comprises a first coil winding, having at least one complete turn about the core, characterized that at least one of the least one turns of the first coil winding comprises a rigid first busbar member and a rigid second busbar member.

An ultrasonic welding apparatus joins metal pieces, such as wires, which are placed in a weldment zone where the metal pieces are subjected to pressure through a compressive height anvil and an adjustable width anvil, and intimate contact is made with a sonotrode of an ultrasonic stack. A first electric motor actuates movement of the height anvil to develop a compressive force for ultrasonic welding of the metal pieces. A second electric motor can position the width anvil before and during welding. A sensor, such as a load cell, measures the compressive force developed. The sensor directly can measure the load on the height anvil independent of the ultrasonic stack. A software algorithm can compensate for deflection of the load cell sensor and lost motion in the first electric motor actuating movement.

A terminal-wire bonding method includes: arranging a first core at a second end of a first terminal-wire having a first terminal connected with the first core exposed from an insulating sheath at a first end, onto a side of an anvil and a second core at a second end of a second terminal-wire having a second terminal connected with the second core exposed, at a first end, from an insulating sheath longer than the insulating sheath of the first terminal-wire, onto a side of a horn; and bonding the first core at the second end and the second core at the second end together by ultrasonic bonding between the horn and the anvil.
