Energy and a control signal may be provided using a coupled power and control cable. The coupled power and control cable may comprise a power cable, a control cable, and an overall jacket. The power cable may be connected between a switch and a fixture and may provide energy to the fixture from the switch. The control cable may be connected between the control circuit and the fixture and may provide the control signal to the fixture from the control circuit. The power cable and the control cable may be disposed beneath the overall jacket.

A ribbon cable with desirable properties including mechanical integrity, resistance to propagation of a flame, and a compact structure is provided. The ribbon cable may be formed by wrapping a flexible layer around a plurality of parallel cable cores. The flexible layer may be adhered to itself and may conform to the outer surfaces of the cores. The flexible layer may, at its edges, overlap such that the edges may be readily adhered to each other. Some or all of the cable cores may be individually shielded. The cable may also include metal foil adjacent one or two sides of the cable cores or, in some instances, encircling the cable cores.

A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration.

Each of the first and second electric wires includes a conductor with a plurality of elemental wires, the second electric wire has a larger conductor cross-sectional area than the first electric wire has, the second electric wire has the larger outer diameter of the elemental wires composing the conductor than the first electric wire has, and the second electric wire contains a same or smaller number of elemental wires composing the conductor in comparison with the first electric wire.

An extruded flexible flat cable includes conductors arranged side by side in a width direction of the extruded flexible flat cable. The conductors are spaced away from each other at a regular interval and an insulator is provided around the conductors by extrusion molding.

A wiring member includes a plurality of wire-like transmission members each including a transmission wire body and a coat covering the transmission wire body and a flattening member keeping the plurality of wire-like transmission members in a flat state. For example, the flattening member is considered to include a first flattening member which is a member formed separately from the plurality of wire-like transmission members.

More particularly, disclosed herein is a patterning formation method including arranging a poly cyclohexylene dimethylene terephthalate (PCT) film as a base film or as an upper part film such as a coverlay film, and patterning a material such as a metal by a printing method or connecting printing electronic technologies on at least a part of the PCT film. Also disclosed herein is a manufacturing method of an electrical device using the same and a vehicular electrical device.

A novel and useful system wiring apparatus and related techniques that address the need to feed power and electronic signals to and from a sample board between the cold, low pressure region in a vacuum chamber and outside room temperature and atmospheric pressure. The wiring apparatus balances electrical resistance with the thermal conductivity of the power and signal conductors. Printed flexible cables are used having an annular sealing region which together with O-rings provide vacuum sealing while allowing electrical signals to pass between integrated circuit(s) inside the vacuum chamber and equipment outside the chamber. A thermal anchor is placed along the printed flexible cable to maintain a desired temperature along the cable. The printed flexible circuits are multilayer with two outer layers serving as an RF shield while two inner layers comprise the signal lines which typically require shielding, electrical isolation from each other and from external electromagnetic fields.

A shielded electrical ribbon cable includes adjacent first and second longitudinal conductor sets where each conductor set includes two or more insulated conductors. The first conductor set also includes a ground conductor that generally lies in the plane of the insulated conductors of the first conductor set. At least 90% of the periphery of each conductor set is encompassed by a shielding film. First and second non-conductive polymeric films are disposed on opposite sides of the cable and form cover portions substantially surrounding each conductor set, and pinched portions on each side of each conductor set. When the cable is laid flat, the distance between the center of the ground conductor of the first conductor set and the center of the nearest insulated conductor of the second conductor set is 1, the center-to-center spacing of the insulated conductors of the second conductor set is 2, and 1/2 is greater than 0.7.
