Abstract

An electrical cable is used to form an internal circuit in an electrical connection box to be mounted on an automobile. An aluminum-based metal conductor is covered with a heat-resistant resin, such as PE (polyethylene) or PBT (polybutylene terephthalate). The conductor is a single core wire or a twisted core wire, which has a plurality of element wires. The conductor is pushed into an insulation displacement slot in an insulation displacement terminal. The insulation displacement terminal is made from an aluminum-based metal or a copper-based metal. A welding material, made of an iron-based metal, welds a contact portion between the conductor and a blade section on an inner peripheral edge of the insulation displacement slot.

Claims

1. An electrical cable used to form an internal circuit in an electrical connection box to be mounted on an automobile comprising:

a conductor made of an aluminum-based metal;

a heat-resistant resin, such as PE (polyethylene) or PBT (polybutylene terephthalate) forming a cover for said conductor; and

said conductor is a single core wire or a twisted wire including a plurality of element wires.

2. A connection structure between an electrical cable and a terminal comprising:

a conductor made of an aluminum-based metal arranged to form an internal circuit in an electrical connection box to be mounted on an automobile;

said conductor is pushed into an insulation displacement slot in an insulation displacement terminal made of an aluminum-based metal or a copper-based metal; and

a welding material made of an iron-based metal welds a contact portion between said conductor and a blade section on an inner periphery of said insulation displacement slot.

3. A connection structure between an electrical cable and a terminal comprising:

a conductor made of an aluminum-based metal arranged to form an internal circuit in an electrical connection box to be mounted on an automobile;

said conductor is pushed into an insulation displacement slot in an insulation displacement terminal made of an aluminum-based metal or a copper-based metal; and

a conductive adhesive is filled in and applied on a contact portion between said conductor and a blade section on an inner periphery of said insulation displacement slot.
