摘要:
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.

A connector-equipped electric-wire bundle including a plurality of types of electric wires different in conductor cross-sectional area and elongation. The connector-equipped electric-wire bundle comprises a first electric wire having a first conductor, and a second electric wire having a second conductor with a greater cross-sectional area and a greater breaking elongation than those of the first conductor. A second connector terminal having, as a second crimp portion, only a conductor barrel and a water-proofing-plug barrel is attached to an end of the second electric wire, and a first connector terminal having, as a first crimp potion, a conductor barrel, a water-proofing-plug barrel and an intermediate barrel is attached to an end of the first electric wire. The intermediate barrel is crimped onto an insulating cover in an intermediate region between the end of the conductor of the first electric wire and a water-proofing plug.
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.

摘要:
A joint connector capable of mutually short-circuiting wires reliably without an increase in the number of components and size thereof. The joint connector (JC) comprises a joint terminal for short-circuiting and a connector housing. The joint terminal includes a plurality of electric contact portions and a short-circuiting portion connecting the electric contact portions. The connector housing has a bottom wall and other walls surrounding a terminal insertion space into which each of the wire-side terminal is inserted, and a lance for locking the inserted wire-side terminal. The lance adapted to be deflected so as to project outwardly from the bottom wall, until the wire-side terminal reaches a proper insertion depth position, to be retracted from the wire-side terminal, and elastically return into the bottom wall, when the wire-side terminal reaches the position. The deflection of the lance allows the insertion of the wire-side terminal to be checked.

Provided is an electronic circuit unit which includes a circuit board, a case for the circuit board and a connector for external connection and can be miniaturized and simplified in structure. This electronic circuit unit includes a circuit board (10) provided with a plurality of conductors for connection (14) on an edge part (12), a case (CS) configured to house the circuit board, and a plurality of terminals (30) provided on ends of a plurality of wires (W). The case (CS) integrally includes a board housing portion (20) and a terminal holding portion (40). The board housing portion (20) holds the circuit board (10) at a specific board holding position. The terminal holding portion (40) holds these terminals (30) in such an arrangement that each terminal (30) comes into contact with each conductor for connection (14) of the circuit board (10) at the board holding position.
