Abstract: A connection method of a terminal includes an inserting-arranging process for inserting and arranging conductors of a plurality of wires into a connection section. The wires have the conductor sections exposed from the sheaths thereof at the end portions. The connection section has cylindrical shape with a bottom portion and an opening section. The method further includes a heating-melting process for heating the connection section in a state that the opening section of the connection section faced upwards in the vertical direction to melt the conductors within the connection section, and a molten-metal raising process for conducting an insertion of the conductors into the connection section and/or a pressurization of the connection section from outside to raise the molten metal within the connection section to a level upper.

Abstract: A method for protecting a terminal-connecting portion of an insulated electrical wire by means of insert molding, the terminal-connecting portion being disposed at one end portion of the insulated electrical wire, comprising the step of: grounding an opposite end portion of the insulated electrical wire before the terminal-connecting portion is introduced into a die.

Abstract: A structure of connection between a coaxial cable and a shield terminal includes the coaxial cable configured to have at least one core wire part made of a conductor, an insulating coating part with which said core wire part is coated, a braided shield with which an outer peripheral surface of said insulating coating part is covered, and an insulating tube with which an outer peripheral surface of said braided shield is covered, the shield terminal that has a cylindrical press bond part pressed and is bonded to the outer peripheral surface of the braided shield, and a ring-shaped crimp member that is pressed and bonded to an outer peripheral surface of the insulating tube.

Abstract: An electric connection terminal includes a contact section for electrical connection to an opposite terminal and a crimping section with the contact section being crimped to cover the conductor and cover of a covered electric wire. The crimping section includes a conductor crimping part to be tightly attached to and crimped around the conductor, a cover crimping part to be tightly attached to and crimped around the cover of the covered electric wire, and a boundary crimping part to be tightly attached to and crimped around the vicinity of a boundary between the cover and conductor. A compression ratio of the boundary crimping part in a state of crimped around the covered electric wire is set to be higher than that of the cover crimping part.

Abstract: A terminal-equipped wire includes a wire and a terminal. The wire includes a core wire and an insulative sheath covering a part of the core wire. The core wire has a plurality of conductive element wires. The terminal includes a wire connection portion connected to the core wire at an end part of the wire where the core wire is exposed. Outer surfaces of the element wires and the wire connection portion are tinned.

Abstract: A conductive metal terminal includes a conductor holding part that holds a conductor of a electrical cable at a distal end side of the conductive metal terminal and a sheath holding part that holds a sheath at a proximal end side of the conductive metal terminal. 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. The sheath holding part includes a bottom plate adjacent to the bottom plate of the conductor holding part and a pair of sheath crimping pieces. The conductor holding part further includes an indent formed in a semi-cylindrical shape and extending from one of the conductor holding part to the other of the conductor holding part. The conductor holding part further includes circular-shaped serrations which are closer to the distal end side than the indent.

Abstract: In a structure of a crimping connection part of an aluminum electric wire and a metal terminal, the aluminum electric wire includes a core wire and an insulating sheath covering the core wire, an exposed core wire in which the core wire is exposed from the insulating sheath at an end portion of the aluminum electric wire is crimped by a core wire crimping part of the metal terminal to form the crimping connection part, and the exposed core wire and the metal terminal of the crimping connection part are covered by a vapor deposited film comprised of an electrically conductive powder.
