A wire with terminal WTis provided with a wireincluding a coreB and an insulation coatingC covering around the coreB, and a terminalincluding a coating crimping portioncrimped to the insulation coatingC. The wireis pulled out rearward from the terminal. A water cut-off memberfor suppressing liquid intrusion into the coreB is disposed between an inner peripheral surfaceA of the coating crimping portionand an outer peripheral surfaceA of the insulation coatingC. The coating crimping portionis provided with an oblique extending portionfor reducing the outflow of the water cut-off memberto outside due to crimping.

Wire with terminal

A wire/terminal production method includes placing a core on a bottom plate and crimping wire barrels to the core by a crimping tool. The crimping tool includes a first tool having a placing surface on which the bottom plate and the core are placed, and a second tool having a curved surface for curving the wire barrels toward the placing surface. The curved surface has a first inclined surface inclined out on a first end in an extending direction of the wire, a second inclined surface inclined out on a second end in the extending direction and a contact surface located between the inclined surfaces. A dimension of the curved surface in the extending direction exceeds a dimension of the wire barrels in the extending direction. A dimension of the contact surface in the extending direction is no greater than the dimension of the wire barrels in the extending direction.

Board with terminal

A crimp terminal may include: a receiving portion that is to receive conductor portions of electrical wires and has an end portion from which the electrical wires are to be lead out; a pair of first barrel portions that are connected to the receiving portion and compress the conductor portions along with the receiving portion; a bend portion that extends from an end portion of the receiving portion and is bent so as to be folded over; and an overlap portion that is connected to the bend portion and overlaps the receiving portion.

Crimp terminal, electrical wire with terminal, and manufacturing method for electrical wire with terminal

A terminal () is connected to a core () of a wire (). The terminal () includes two wire barrels (L,R) extending from a bottom portion () on which the core () is placed. The wire barrels (L,R) are crimped to wind around the core (). The core () includes strands () made of metal having a larger tensile strength than metal of the female terminal (). At least first, second and third strands (J,K) and (L) are disposed side by side in a direction intersecting an extending direction of the core () inside the wire barrels (L,R). A tip of the wire barrels (L,R) is inserted between the first and second strands (J,K) and a tip of the other of the pair of wire barrels (L,R) is inserted between the second and third strands (K,L).

A wire with terminal () includes at least one wire () having a core () and a terminal () connected to the wire (). The terminal () includes a wire barrel () to be caulked and crimped to the core (). At least one end part of the wire barrel () in an extension direction of the wire () is provided with an enlarged diameter portion () enlarged in diameter toward the one end part. At least one recess (E) is provided at a position corresponding to the enlarged diameter portion () and in a region configured to come into contact with the core () in a placing surface () of the wire barrel () where the core () is arranged.

A female terminal () to be connected to an end of a wire () in which a core () is covered with an insulation coating (), and the wire () being pulled out rearward therefrom. The female terminal () includes two coating crimping pieces () extending in opposite lateral directions intersecting a pull-out direction of the wire () and to be crimped to an outer peripheral surface of the insulation coating (). Compressing portions () are formed on the surface of each coating crimping piece () that faces the insulation coating () and are disposed adjacent a front edge of each coating crimping piece (). Each compressing portion has an internal space narrowed toward a rear end from the front edge of the coating crimping piece ().

Structure for improving impact strength of a terminal

A wire with terminal includes a wire in which a core is covered with a coating, and a terminalincluding a wire barrelto be crimped to the core exposed from the coating of the wire and an insulation barrelto be crimped to the coating of the wire. The wire is pulled rearwardly from the terminal. RecessesB are provided on a surface of the insulation barrelto be crimped and openings of the recessesB are shaped to become narrower toward a rear side. As the wire is pulled more rearwardly, the coating penetrating into the recessesB moves rearwardly of the recessesB to be compressed and hardened and becomes less likely to come out of the recessesB. Thus, impact strength can be enhanced.

Wire with a crimped terminal

A production method for a terminal-equipped electrical wire in which a terminal including a bottom plate portion and a pair of wire barrels extending sideward from the bottom plate portion is crimped to a core wire exposed at an end of an electrical wire, includes: a step of placing the core wire on the bottom plate portion; and a step of allowing the wire barrels to surround the core wire and be crimped to the core wire using a crimp tool, wherein the crimp tool includes a first tool having a placement face on which the bottom plate portion and the core wire are placed, and a second tool having a curved face for holding and curving the wire barrels between the curved face and the placement face, and a surface roughness Ra2 of the curved face is larger than a surface roughness Ra1 of the placement face (Ra2&#x3e;Ra1).

A terminal () includes a connecting portion () to which a plurality of wires () including conductors () having different thicknesses are to be connected side by side, and the connecting portion () is stepped. A terminal-wire assembly () includes a plurality of wires () including conductors () having different thicknesses and a terminal () including a connecting portion () to which the plurality of wires () are to be connected side by side, and the connecting portion () is stepped. In the terminal-wire assembly (), the wire () connected at a high position on the connecting portion () includes the thinner conductor () than the wire () connected at a low position on the connecting portion ().

Terminal, terminal-equipped electrical wire, and method for manufacturing terminal-equipped electrical wire

A terminal that is connected to an end of an aluminum electric wire obtained by covering core wires with an insulating cover. The terminal is provided with a pair of insulation barrel pieces (crimping pieces) that extend in directions that intersect the longitudinal direction of the aluminum electric wire, and are crimped to the outer circumferential surface of the insulating cover. The pair of insulation barrel pieces have tip end portions that face and abut against each other in a state in which the pair of insulation barrel pieces are crimped to the insulating cover.

Terminal and terminal-equipped electric wire

A wire with crimped terminal is provided with a wire and a crimped terminal connected to a terminal portion of the wire. The crimped terminal is provided with a board-shaped base portion where the wire is arranged; a counterpart member connector provided at a forefront end of the base portion; a pair of core wire crimp tabs crimped to a core wire portion of the wire; and a pair of sheath crimp tabs crimped to an insulated sheath portion of the wire. The core wire crimp tabs are each provided with an inwardly-recessed contracted portion on both sides of the core wire crimp tab in an X axis direction, in an area closer to the base portion than a leading edge portion of the core wire crimp tab, the contracted portion thereby having a smaller width in the X axis direction.
