An object is to obtain a stable electric connection resistance under a mild crimping condition. The present invention is a terminal connector 12 that includes a crimp portion 30 to be crimped to an electric wire. The crimp portion 30 includes a base material, an aluminum layer or an aluminum alloy layer a surface on the base material, and a hard layer on a surface of the aluminum layer or the aluminum alloy layer. The hard layer is harder than the base material. The present invention may be an electric wire with a terminal connector 10 that includes the above terminal connector 12 and a covered electric wire 40 that includes a core wire 42 made of aluminum or aluminum alloy. The crimp portion 30 of the terminal connector 12 is crimped to the core wire 42.

A connector includes a terminal member including a contact portion that can be brought into contact with a connecting target member, the terminal member being attached to an end of a wiring material, a housing including an insertion recess into which the connecting target member can be inserted, the housing retaining the terminal member such that the contact portion can be brought into contact with the connecting target member inserted into the insertion recess, and a dust protection member that protects the insertion recess against dust by blocking an insertion opening of the insertion recess. The dust protection member is formed such that the dust protection member can be penetrated by the connecting target member when the connecting target member is inserted into the insertion recess.

A method for manufacturing an electric wire with a terminal, includes crimping a barrel portion of the terminal onto a core wire constructed of metal wires and creating a crack in a metal oxide layer immediately before the crimping. The metal oxide layer is formed on a metal surface of the core wire. The creating of crack is accomplished by applying a mechanical force to the metal oxide layer.

Provided is a crimp terminal designed to be crimped onto an end portion of an electric wire to form a terminal-equipped electric wire, achieving both of ensuring mechanical strength of the terminal-equipped electric wire and reducing a contact resistance between the electric wire and the crimp terminal. The crimp terminal comprises an electric contact section and an electric-wire crimp section to be crimped onto a conductor in the end portion of the electric wire, the crimp terminal being formed of a metal plate which has a copper-containing plate body and a tin-plating layer covering a surface of the plate body. In the crimp terminal, the tin-plating layer has a smaller thickness in a crimp surface region where the electric-wire crimp section is to make contact with the end portion of the electric wire is less than that in an electrical contact surface region where the electric contact section is to make contact with a counterpart terminal.

Rims of an opening of each recess form a parallelogram, and comprise two first opening rims that are parallel to a first direction and two second opening rims that are parallel to a second direction. The first opening rims of each of the recesses that are aligned along the first direction are arranged on a straight line along the first direction. The second opening rims of each of the recesses that are aligned along the second direction are arranged on a straight line along the second direction. The recesses are formed by pressing a wire barrel with a die where a plurality of protruding parts are formed so as to correspond to the recesses.

A wire barrel to be crimped onto an end of an electric wire has a surface on a side to face the electric wire. The surface has a plurality of recesses that extend in a direction that is to cross the axial direction of the electric wire and are separated from each other in the direction that is to cross the axial direction of the electric wire. The wire barrel has a thickness in a range from 0.15 mm to 1 mm before being crimped to the electric wire. Each recess has a depth in a range from 30% to 60% of the thickness of the wire barrel before the wire barrel is crimped onto the electric wire.

A plurality of recesses are formed on a surface of a wire barrel where an electric wire is provided. In a state before the electric wire is crimped onto the wire, barrel, at least one of sides comprising rims of an opening of each recess of a quadrangular shape is a crossing side crossing at an angle of from 85 degrees to 95 degrees to an extending direction. In a state before the electric wire is crimped onto the wire barrel 16, the crossing sides of a plurality of recesses positioned adjacent to each other in the extending direction are so arranged as to overlap with each other in the extending direction.

An electric wire with terminal connector including an electric wire having a core wire including a plurality of wires and a female terminal connector including a wire barrel that is crimped onto the core wire exposed from the electric wire, the following steps are executed. The steps include a step of removing wire insulation covering an outer peripheral surface of the core wire to expose the core wire, a step of holding the exposed core wire with jigs provided in a pair and applying ultrasonic vibration to the core wire via the jigs, and a step of crimping the wire barrel so as to surround a part of the core wire to which the ultrasonic vibration is applied.
摘要:
A crimp terminal whose crimp state can be easily evaluated and to provide a method of manufacturing a terminal-provided wire comprising the crimp terminal. The crimp terminal includes a pair of conductor barrels which are crimped onto a conductor of an electric wire. The conductor barrel has an outer surface provided with a crimp state indicator for evaluating a crimp level thereof. The indicator may be a mark so shaped that a position of an internal end of an outwardly exposed part thereof is varied in a terminal axial direction corresponding to the crimp level, or include a plurality of marks spaced in a direction perpendicular to the terminal axial direction.
