The conductor crimping portion includes a serration extending in a groove shape across the pair of conductor tightening pieces and the bottom plate in a direction intersecting an extending direction of the conductor to be disposed on the bottom plate, and a width of an opening of the serration is equal to or larger than a width of a bottom surface of the serration.

Crimping terminal

A terminal-equipped electric wire includes an electric wire in which a core wire including a plurality of strands is covered with a covering, and a terminal fitting attached to the electric wire. The terminal fitting includes a core wire connection body physically and electrically connected to the core wire. The core wire connection body has a bottom, a pair of cantilever side walls erected from the bottom and arranged facing each other with a space therebetween, and at least one set of paired pressure contact bodies arranged facing each other with a space therebetween between the pair of side walls so as to come into pressure contact with the strands in an outermost layer of the core wire.

Terminal-equipped electric wire

A core-wire exposed portion in an electric wire and at least one pair of pressure-welding pieces made of an electroconductive material are included. The core-wire exposed portion is a portion is which a core wire composed of a plurality of element wires is exposed. The pair of pressure-welding pieces are provided with a core wire pressure-welding section in which pressure-welding end surfaces are disposed facing each other at a distance and Kate the core-wire exposed portion press-fitted between the pressure-welding end surfaces. The core wire pressure-welding section is formed as a section that brings all of the element wires in the core-wire exposed portion, between the pressure-welding end surfaces, into contact with either of the pressure-welding end surfaces while being in an aligned state.

A terminal-wire bonding method includes: arranging a first core at a second end of a first terminal-wire having a first terminal connected with the first core exposed from an insulating sheath at a first end, onto a side of an anvil and a second core at a second end of a second terminal-wire having a second terminal connected with the second core exposed, at a first end, from an insulating sheath longer than the insulating sheath of the first terminal-wire, onto a side of a horn; and bonding the first core at the second end and the second core at the second end together by ultrasonic bonding between the horn and the anvil.

Terminal-wire bonding method and bonded terminal-wire

A connector is provided that is easy to assemble. A terminal fitting is arranged on a base of a housing, a conductor portion is inserted into a tubular portion of a conductor connection portion, and a lid portion is assembled on the base. Thus, an insertion portion is inserted between extension portions to that intersect each other, and a diameter of the tubular portion is reduced. The conductor portion is tightened by the tubular portion, and the conductor connection portion is connected to the conductor portion. Therefore, a dedicated machine is not required to connect the terminal fitting to an electric wire, and operation of connecting the terminal fitting to the electric wire and of accommodating the terminal fitting in the housing can be performed substantially simultaneously. Thus, the connector can be easily assembled.

A wire bonding method includes: arranging a first core including a plurality of strands exposed from an insulating sheath of a first wire, onto a side of an anvil and a second core including a plurality of strands exposed from an insulating sheath of a second wire, onto a side of a horn for ultrasonic bonding, the second core being larger in sectional area than the first core; and bonding the first core and the second core together by ultrasonic bonding between the horn and the anvil.

Wire bonding method and bonded wire

A bonding method for a conductor of an electric wire including a conductor formed of a plurality of strands and a sheath covering the conductor such that the conductor is exposed to a predetermined length. The bonding method includes bonding the strands to each other, the strands being spaced apart from the sheath by a predetermined length. An outer diameter of a middle portion of the conductor between a bonded portion and a portion covered with the sheath gradually decreases toward the bonded portion. A maximum value of an intersection angle between an upper surface of the bonded portion or a longitudinal direction of the electric wire and the strands of the middle portion is smaller than a predetermined angle. The predetermined angle is an angle at which breakage of the strands is prevented when the bonding is performed.

Bonding method for conductor of electric wire and electric wire

An electric wire with a terminal and manufacturing method thereof is provided. In the electric wire with the terminal, the protective member, the core wire, and the terminal fitting are integrally connected to each other by ultrasonic vibration applied via the protective member from an ultrasonic horn in a state in which the core wire is sandwiched between the protective member and the terminal fitting. Therefore, there is no possibility that the ultrasonic horn directly presses the core wire, and the edge (particularly, the rear edge) of the pressing portion of the ultrasonic horn is direct in contact with the core wire. Thereby, at the time of ultrasonic bonding, stress concentration due to the edge (particularly the rear edge) of the pressing portion of the ultrasonic horn with respect to the core wire can be relaxed, and disconnection of the core wire can be suppressed.

The electric wire includes a sheath; a conductor having a covered portion covered by the sheath and an exposed portion exposed due to absence of the sheath over a predetermined length at a part of the electric wire in a longitudinal direction of the electric wire; and a bonded portion formed over a predetermined length at a part of the exposed portion, the bonded portion at which strands of the conductor are bonded. An end of the wire barrel on a sheath side is closer to the sheath than an end of the bonded portion on the sheath side. The wire barrel covers at least a part of the bonded portion.

Terminal-equipped electric wire and method of manufacturing terminal-equipped electric wire

A method for manufacturing a terminal-equipped electric wire includes forming, in an electric wire, a bonded portion in which strands of a conductor exposed due to absence of a sheath are bonded to each other. A terminal including a wire barrel portion is fixed to the electric wire such that the wire barrel portion covers at least a part of the bonded portion. A sectional shape of the bonded portion before the fixing of the terminal is formed in such a shape that a variable range of a value of a distance between a geometric center of a cross section of the bonded portion and the wire barrel portion falls within a range of 0.71 to 1.29 when rotating the bonded portion by an arbitrary angle while engaging the bonded portion with the wire barrel portion within the wire barrel portion.

A bonding method for a conductor of an electric wire includes a conductor formed of a plurality of strands and a sheath covering the conductor such that the conductor is exposed to a predetermined length. The bonding method ultrasonically bonds the plurality of strands of the electric wire to each other using an anvil and a horn. When the strands are ultrasonically bonded to each other by clamping a part of the conductor exposed from the sheath between the anvil and the horn throughout a predetermined length and ultrasonically vibrating the horn, a distance from the anvil or the horn to the sheath of the electric wire is shorter than a length of the strands when the strand vibrates in a primary mode by ultrasonic vibration.

A method for manufacturing an electric wire with a terminal includes forming a bonded part in which outer peripheral surfaces of strands are bonded to one another on an end portion of a core wire having the strands, in an electric wire in which the end portion is exposed from a covering; installing the bonded part onto a crimp terminal including a bottom part and a pair of caulking pieces extending from the bottom part and facing each other; crimping the caulking pieces to the bonded part, by sandwiching the crimp terminal and the electric wire between a first mold supporting the crimp terminal and a second mold moving relative to the first mold; and cutting a tip end portion projecting to outside from the caulking pieces in the bonded part by a cutting unit, while the caulking pieces are pressing the bonded part toward the bottom part.
