An aluminum electric wire includes an annealing conductor that is made up of elemental wires made of an aluminum alloy containing 0.90-1.20 mass % Fe, 0.10-0.25 mass % Mg, 0.01-0.05 mass % Ti, 0.0005-0.0025 mass % B, and the balance being Al and has a tensile strength of 110 MPa or more, a breaking elongation of 15% or more, and an electric conductivity of 58% IACS or more, and an insulating material covering the conductor. The wire is produced by casting an aluminum alloy prepared by rapidly solidifying a molten aluminum alloy having the above composition, producing the wires by subjecting the alloy to plasticity processing, producing the conductor by bunching the wires, subjecting the wires or the conductor to annealing at 250&#xb0; C. or higher, and then covering the conductor with the insulator.

Aluminum electric wire for an automobile and a method for producing the same

A process of producing a flame-retardant silane-crosslinked olefin resin, an insulated wire, and a process of producing an insulated wire. The process includes kneading and molding a silane graft batch containing a silane-grafted olefin resin in which a silane coupling agent is graft polymerized onto an olefin resin, a flame retardant batch in which an olefin resin is mixed with a flame retardant containing metal hydroxide, a catalyst batch in which an olefin resin is mixed with a silane crosslinking catalyst, and water crosslinking the batches after kneading and molding. A mass ratio of the flame retardant batch to the silane graft batch is 60:40 to 90:10, and the catalyst batch amount is 3 to 10 part by mass with respect to 100 part by mass of a component of the silane graft and flame retardant batches. The wire is prepared by covering a conductor with the silane-crosslinked olefin resin.

A conductor for an automobile is provided. The conductor is configured by compressing a plurality of surrounding wires that surround a central wire. Individual wires of single materials are combined in various combinations. Materials from which individual wires are formed in one embodiment are one of stainless steel, copper or copper alloy. Materials from which individual wires are formed in another embodiment are one of stainless steel, aluminum or aluminum alloy.

Electric wire for automobile

A conductor for an automobile is provided that exhibits the characteristics of slender structure, improved strength and reduced weight. The conductor is configured by compressing a plurality of surrounding wires that surround a central wire. Individual wires of differing materials are combined in various combinations to achieve the slender structure, improved strength and reduced weight. Materials from which individual wires are formed in one embodiment are one of stainless steel, copper or copper alloy. Materials from which individual wires are formed in another embodiment are one of stainless steel, aluminum or aluminum alloy.

A cover of a simple construction is provided which can deal with a distance variation between battery posts. The cover 6 is made of a rubber material and has a narrow box-like configuration. A bottomed middle portion of the cover 6 forms a tubular portion 107 through which a braided wire 3 of a battery connection terminal 1 is to be passed, and the opposite ends thereof form post cover portions 108 for covering battery posts 2. Further, slits 9 are formed in side walls between the tubular portion 107 and the post cover portions 108, so that the post cover portions 108 can be bent upward. In this way, since the cover 6 can be elongated and contracted according to a distance between the battery posts 2, it can be easily mounted and the action of an undesired force on the cover 6 due to the vibration of batteries 5 can be effectively prevented.
