Abstract:
1. A crimping structure of a conductive metal terminal in which the conductive metal terminal is connected to an aluminum electrical cable including a conductor formed by twisting a plurality of aluminum or aluminum alloy wires and a sheath made of an insulating material and covering on an outer circumference of the conductor, by crimping the conductive metal terminal on the aluminum electrical cable, the conductive metal terminal comprising: a conductor holding part that holds the conductor of the aluminum electrical cable at a distal end side of the conductive metal terminal; and a sheath holding part that holds the sheath of the aluminum electrical cable at a proximal end side of the conductive metal terminal, wherein the conductor holding part includes a bottom plate on which the conductor of the aluminum electrical cable is placed and a pair of conductor crimping pieces provided to be continuous to the bottom plate and sandwich the conductor on the bottom plate of the conductor holding part, the sheath holding part includes a bottom plate adjacent to the bottom plate of the conductor holding part and on which the sheath is placed, and a pair of sheath crimping pieces provided to be continuous to the bottom plate of the sheath holding part and sandwich the sheath on the bottom plate of the sheath holding part, the conductor holding part further includes an indent on a sheath holding part side of the conductor holding part and having a semi-cylindrical shape extended along the indent and raised from an inner surface of the conductor holding part, the indent extending from one conductor crimping piece of the pair of conductor crimping pieces to another conductor crimping piece of the pair of conductor crimping pieces through the bottom plate of the conductor holding part and being raised perpendicular to an axis direction of the crimped conductor of the aluminum electrical cable, the conductor holding part further includes circular-shaped serrations on an upper surface of the bottom plate of the conductor holding part and on the pair of conductor crimping pieces, and the circular-shaped serrations are closer to the distal end side of the conductive metal terminal than the indent.
