Abstract: A flat cable conductor has: a conductor made of copper or a copper alloy; a first plating film made of tin and/or a tin-copper alloy, the first plating film being formed around the conductor; and a second plating film made of an alloy of tin and a third element selected from Au, Ag, Ni, Ge, Zn and Bi, the second plating film being formed around the first plating film. The third element has a concentration of 0.01 or more and 80 or less wt % at an outer surface of the second plating film.

Abstract: An interconnection assembly has phase parts for U phase, V phase and W phase. The phase parts each are of a plurality of interconnection assembly parts that are connected in the form of a ring and include a conductor section to which a motor coil wire is connected, the conductor section being formed by stripping fluororesin insulation at a predetermined position, and the phase parts are partially fixedly bundled.

Abstract: A flexible flat cable has a single conductor or a plurality of conductors, juxtaposed to each other or one another, which are sandwiched between a pair of plastic films with an adhesive to form an integral structure. The plastic films with an adhesive have a modulus of longitudinal elasticity of not less than 300 kg/mm2 and an elongation of not less than 20%. The plastic films are formed of a polyimide. The adhesive is formed of an epoxy having a glass transition temperature Tg of 80° C. or above, and the 180° peel strength between the adhesive and the single conductor or the plurality of conductors is not less than 0.5 kg/cm.

Abstract: In FFC1 integrated by sandwiching flat type conductors 2 between plastic films 3 with adhesives, wherein the conductors are formed of pure copper or a copper alloy having a wiredrawing draught of at least 95% and an elongation of at least 5%, and the plastic films with adhesives are formed of one having a modulus of longitudinal elasticity of at least 280 kg/mm2 and an elongation of at least 80%, and the 180° peel strength between the adhesives and the conductors 2 is made to be at least 0.8 kg/cm. As a result, even if the number of conductors 2 is increased than the conventional FFC, bending-resistant characteristic equal to or higher than the conventional FFC can be exhibited.

Abstract: In a flexible flat cable comprising a single conductor or a plurality of conductors, juxtaposed to each other or one another, which are sandwiched between a pair of plastic films with an adhesive to form an integral structure, the plastic films with an adhesive each are formed of a polyimide with an adhesive which has a modulus of longitudinal elasticity of not less than 300 kg/mm2 and an elongation of not less than 20%, the adhesive is formed of an epoxy having a glass transition temperature Tg of 80° C. or above, and the 180° peel strength between the adhesive and the conductor is not less than 0.5 kg/cm. By virtue of this constitution, a novel flexible flat cable can be realized which has significantly improved heat resistance and, at the same time, has excellent flex resistance even at a high temperature of 80° C. or above.

Abstract: A metal-shielded cable includes a core made of insulated wires each having a conductor coated with an insulation layer. The core is surrounded with a composite metal shield which includes a laminated metal-plastic layer and a shield layer. The shield layer includes a tape formed of woven filaments, which is wound around or aligned longitudinally along the core of the cable.

Abstract: A screw including a head and a shaft having a helically threaded portion and a barbed portion is provided. In operating the barbed portion driven into a hole by pressure on the head in the axial direction. When the barbed portion is completely driven into the hole, the threaded portion comes into contact with the wall of the hole for driving the screw slightly further into the hole in this manner tight engagement between the two members fastened by the screw can be achieved. The barbed portion is so formed as to prevent removal of the screw.
