Abstract: Concentric Compressed Unilay Stranded Conductors are formed of certain combinations of compressed wires, such as 1+7+12, 1+6+11 or 1+7+12+17, which have nominally equal diameters. The combinations of conductors or wires are selected so that the number of wires in any two adjacent layers, including a central layer, are not divisible by a common number with the exception of the integer one. The stranded conductors are optionally formed to have sectored cross-sectional configurations.

Abstract: The present invention provides a wire for a press-connecting terminal which has a high flexibility, and achieves a high reliability for a connection portion at the time of press-connection, and also provides a method of producing a conductor of such a wire. The wire provides a stranded conductor and an insulator covering the conductor. Wire elements of the stranded conductor are concentrically twisted in layers in the same direction at the same pitch, and the stranded conductor is compressed into a circular cross-section in such a manner that a space factor of the cross-section of the conductor is not less than 99%. The present invention also provides a multi-layer compressed concentric stranded conductor which enables a uniform compression of a base stranded wire.

Abstract: An electrical path or interconnection arrangement is provided within a formed support body of polymeric material that exhibits volumetric changes during and after the forming thereof. The electrical path or interconnection arrangement provides an accurately positioned electrically conductive path through the material of the support body and also responds to, accommodates and alleviates the effects of forces at the interface between the material of the support body and the electrical path or interconnection arrangement that occur during and after the forming of the support body. The interconnection arrangement exhibits predetermined deformability/compressibility characteristics to alleviate stresses caused by the volumetric changes of the polymeric material. In a preferred arrangement, the interconnection arrangement includes an elongated tubular conductor fabricated from a metallic material.

Abstract: Concentric Compressed Unilay Stranded Conductors are formed of certain combinations of compressed wires, such as 1+7+12, 1+6+11 or 1+7+12+17, which have nominally equal diameters. The combinations of conductors or wires are selected so that the number of wires in any two adjacent layers are not divisible by a common number with the exception of the integer one. Compression of wires in one or more layers is such as to provide area reductions within the range from 0 to approximately 19% for the layers affected.

Abstract: An electrical cable assembly includes a plurality of electrical conductors supported within an insulative casing. The conductors are arranged in side-by-side transversely spaced position and the casing surrounds and electrically isolates each of the conductors. The casing includes a major planar surface permitting mass termination to a connector. One of the conductors includes a flat surface portion which faces an adjacent one of the side-by-side conductors and also includes a curved surface portion which faces the major planar surface.

Abstract: A cable for the transmission of signals from an amplifier to a loudspeaker which includes two insulated conductors forming respective leads, and a sheath enclosing the two leads. The conductors can be solid wires having a smooth surface and made of oxygen-free copper. In the alternative, the conductors can be composed of elementary wires, the elementary wires of each conductor being stranded together in the same wire drawing direction, and the conductor composed of the stranded elementary wires being of a unilay structure, the conductor being additionally compressed.

Abstract: A method of forming an electrical cable assembly includes providing a plurality of round electrical conductors. One of the conductors is flattened along a longitudinal surface portion. The conductors are arranged in side-by-side transversely spaced position with the flattened portion of the one conductor facing an adjacent conductor. An insulative casing is extruded about the conductors and includes a major planar surface permitting mass termination to a connector. The one conductor includes a curved surface portion which faces the major planar surface.

Abstract: An electric cable to be used as phase winding of a three-phase alternating current winding for linear motors. The cable has a compacted, soft-annealed stranded conductor (5) on which a conductive layer (7) is firmly anchored. The insulation (8) and the outer conductive layer (9) are applied in the same operation as the extruded inner conductive layer (7) and are firmly attached to the latter. A sheathing (10) which is of good electrical conductivity and mechanically stable is applied over the outer conductive layer (9).

Abstract: An insulated conductor for a wire harness comprising a conductor and an insulation with which the conductor is covered, the insulation being formed of thermoplastic polyurethane having shore D hardness of more than 50, thickness of less than 0.2 mm, and an adherence of the insulation to the conductor less than 2 Kg/10 mm, being measured as the required force to pull 10 mm of the insulation off the conductor.

Abstract: An audio cable in which a plurality of outer conductors surround one or more inner conductors. The outer conductors provide a path for the relatively high frequency components of the signal and the inner conductors provide a path for the relatively low frequency components of the signal. The length of each outer conductor is greater than the length of the inner conductors and the outer conductors are wound around the inner conductors so that the frequency components of the signal arrive at the end of the end of the cable at the same time.

Abstract: The method of the invention enables the manufacture of flat, rectangular cable from fine-gauge, self-bondable magnet wire. The cable is capable of efficiently transmitting electrical currents at high frequencies.

Abstract: A plastic fiber cable has a flame retardant sheath which contains between 10-40% by weight of an inert filler, preferably titanium dioxide, which provides the sheath with thixotropic non-drip properties so that as well as possessing non-flammability properties the sheath when molten will also not drip and thus will not expose more flammable materials, such as the strands, inside the sheath.

Abstract: A cable comprised of coated conductors, wound together and compacted, has an insulating strip interposed between the two layers in which the conductors are disposed, to ensure good insulation therebetween. Apparatus for producing the cable includes a stranding machine, with which a hollow mandrel is used for the purpose of introducing the insulating strip between the layers of conductors, and a method for producing the cable is also provided.

Abstract: This invention relates to an electrical cable useful in large power transformers and reactors. The cable is composed of a plurality of separate ropes which are generally of the same size and configuration which may be combined in accordance with a predetermined plan to form a complete cable.

Abstract: A compressed, multi-layered, concentric layer stranded cable electrical conductor with each succeeding overlying layer of strands helically wound in an alternately opposite direction, comprising the product of sequentially circumferentially compressing each succeeding overlying layer of cross lay strands to a regressively reduced state of consolidation.
