The terminal connection strip includes: a carrier formed in a strip shape; and a plurality of terminal fitting which project from at least one edge side of the carrier in a width direction. The terminal fitting includes a crimping section which connects by crimping at least a conductor tip of an insulated wire provided with the conductor tip where a conductor is covered with an insulating cover and the conductor is exposed by peeling off the insulating cover on a distal end side of the insulated wire to the terminal fitting. The crimping section is formed into a hollow shape which allows the insertion of at least the conductor tip from a proximal end side of the crimping section and allows the crimping section to surround the conductor tip.

Wire crimping device

A crimp terminal includes a crimp portion formed in a tubular shape with an electrically conductive the substrate and configured to crimp join with an electric wire, and a sealing portion formed at one end of the crimp portion and seals against an electric wire to be crimp joined to the crimp portion. At the sealing portion, the substrate is bent and lapped and continuously joined from one end portion to another end portion of this overlapped portion. One end of a joining trajectory is at a position that is deviated on a side opposite of the crimp portion with respect to the sealing portion.

Crimp terminal, connecting structure, manufacturing method of the crimp terminal, and laser welding method

A terminal manufacturing apparatus includes a pressing device adapted to form a chained terminal including a crimp portion by bending a continuously supplied plate-shaped workpiece into a hollow shape, the crimp portion being crimpable with a conductor part of a coated conductor accommodated therein, a welding device adapted to bring two edge portions of the crimp portion in proximity to each other and join the two edge portions by welding, a conveying/positioning time calculating unit adapted to determine a conveying/positioning time of the welding device on the basis of a machining time required by the pressing device and the welding device, and a conveying/positioning mechanism adapted to position the chained terminal in a welding machining position within the welding device in accordance with the conveying/positioning time.

Terminal manufacturing apparatus and welding apparatus

A crimp terminal has a crimp portion that is formed by bending a plate material into a hollow shape and that has at one end thereof an opening capable of accommodating and crimping a conductor portion of a coated wire. The crimp terminal includes a first weld portion obtained by bringing two edge portions of the crimp portion in close proximity to each other and joining by laser welding, and a second weld portion obtained by forming a lapped portion by overlapping of a transition portion formed at an opposite end of the crimp portion to the opening, and closing the lapped portion by laser welding. A welding trajectory in the second weld portion is constituted by a curve, a plurality of straight lines, or a discontinuously formed line.

Terminal, crimp terminal, wire harness, and method for manufacturing crimp terminal

A terminal includes a tubular crimp portion that crimp connects with an electric wire. The tubular crimp portion is composed of a metal member. The tubular crimp portion includes a non-weld portion and a weld portion, the weld portion being formed by welding. A metal base material constituting the metal member of the non-weld portion includes a normal portion and an annealed portion.

Terminal, method of manufacturing terminal, and termination connection structure of electric wire

A laser welding apparatus that welds a butted interface of a workpiece by laser light irradiation while successively feeding the workpiece having the butted interface to a welding position includes an X- and Y-axis scanner that scans laser light outputted from a laser light source in an X-axis direction and a Y-axis direction which are orthogonal to each other, a measuring device that measures a dimension along the butted interface, and a scanner control device that controls driving of the X- and Y-axis scanner so as to weld the butted interface by laser light irradiation.

Terminal connection strip, method of manufacturing crimp terminal, wire crimping device, and method of crimping wire

A method for manufacturing a crimp terminal having a crimp portion that allows crimp connection to a conductor part of a coated wire includes forming a tubular body by bringing together side edges of a plate material made of metal composed of a copper alloy having a copper content ratio of greater than or equal to 70%, irradiating a periphery of the sides edges, which are brought together, with laser light from a laser irradiation unit to weld the side edges which are brought together, and setting a power density of the laser light and a sweep rate of the laser light in such a manner that a weld bead formed at the side edge portion after the welding has a width of 80 &#x3bc;m to 390 &#x3bc;m.

Method for manufacturing crimp terminal, crimp terminal, and wire harness

A method for manufacturing a crimp terminal having a crimp portion adapted to allow crimp connection with a coated wire having a conductor and an insulating coating, the crimp portion being adapted to crimp connect along the coated wire from a portion of the conductor coated with the insulating coating to a portion of the conductor exposed from the insulating coating at a tip of the coated wire includes providing a barrel member formed by arranging edges of a copper alloy plate material side-by-side, the barrel member having a diameter reducing on an end portion side in a longitudinal direction from a coating crimp portion, forming the crimp portion by welding the edges by laser irradiation from a laser irradiation unit onto a position where the edges are arranged side-by-side, while moving a laser light irradiation position in a longitudinal direction of the barrel member, and irradiating laser light with an output power density and a sweep rate for causing fine molten metal particles having a diameter of 60 &#x3bc;m or less to ejected from the weld portion during laser welding to adhere to an inner surface of the barrel member.

Crimp terminal, and method and apparatus for manufacturing a crimp terminal

A barrel portion which allows the pressure-bonding connection of an aluminum core wire exposed on a distal end of an insulated wire covered with an insulating cover is formed into a cylindrical shape by bending barrel portion corresponding portions of a terminal base material in a terminal developed state about a terminal axis. In abutting end portions where the barrel portion corresponding portions abut each other, a welded part which welds the end portions is formed along a long length direction of the insulated wire. The welded part is formed on an upper surface concave portion and a projecting portion where an amount of plastic deformation of a conductor pressure-bonding section generated along with the pressure-bonding of the conductor pressure-bonding section becomes larger compared to other portions in a circumferential direction of the conductor pressure-bonding section.
