In a terminal-equipped electric wire in which a first barrel of a crimp terminal is crimped to a core wire exposed portion of an electric wire, a second barrel of the crimp terminal is crimped to a covering portion of the electric wire, and an anticorrosive portion is formed at least in an opening portion between the first barrel and the second barrel, an adhesive member is arranged on an outer peripheral surface of the covering portion, a base member and adhesive layers of the adhesive member are held in an elastically deformed state by being crimped by the second barrel, the inner adhesive layer of the adhesive member adheres to the entire circumference of the outer peripheral surface of the covering portion, and the outer adhesive layer of the adhesive member adheres to the entire circumference of an inner peripheral surface of the second barrel.

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

A terminal-equipped electric wire includes: an electric wire in which a conductor is covered by an insulating cover; a crimp terminal including a conductor crimping portion crimped to the conductor exposed from an end of the insulating cover, a cover crimping portion crimped to the insulating cover, and an intermediate portion that couples the conductor crimping portion and the cover crimping portion and in which the conductor is exposed; and a anticorrosive material covering at least the conductor exposed in the intermediate portion. The intermediate portion has grooves that are provided on a surface on the conductor side and formed from both end portions in a circumferential direction such that each of the grooves is formed toward a center side in the circumferential direction.

Terminal-equipped electric wire with exposed wire having insulative sheath covering end part crimped and protected with anticorrosive material

A terminal crimping apparatus includes a terminal supply device configured to supply a terminal chain member including a plurality of crimping terminals, a first mold including a first edge portion provided at one end of a supporting surface supporting the crimping terminals, a second mold configured to crimp the crimping terminal onto a wire by sandwiching the crimping terminal between the second mold and the supporting surface, and a terminal cutting member including a second edge portion. The terminal cutting member cuts a boundary with the crimping terminal in a link portion using the second edge portion.

Terminal crimping apparatus

An electric wire with a terminal includes an electric wire, and a crimping terminal including an electric wire connection portion crimped by being wound around a core and a cover of the electric wire, a diameter expansion portion which contains a water stop member covering a tip end portion of the core and sealing a gap between the core and the electric wire connection portion is provided in an end portion of the electric wire connection portion on a tip end side of the core, and a sectional area of the diameter expansion portion is greater than a sectional area at a portion on the base end side of the core with respect to the diameter expansion portion.

Electric wire with terminal and manufacturing method of electric wire with terminal

A crimp terminal included in a wire harness includes an electrical connecting portion, a conductor caulking portion, and a coat caulking portion. The conductor caulking portion includes a first base to which the electrical connecting portion is joined at one side in an axial direction and to which the coat caulking portion is joined at the other side, and a pair of first barrel pieces that extend from the first base and wrap the conductor of the wire between the first base and the pair of first barrel pieces and caulked. The pair of first barrel pieces include bell-mouth portions at end portions close to the coat caulking portion. The first base has a first protrusion at a position facing base ends of the bell-mouth portions across the conductor, having a recessed portion on the conductor side and protruding away from the conductor, and extending in a crossing direction.

Crimp terminal and wire with crimp terminal

Terminal fitting for electric connector

A crimp terminal includes a wire connection portion including a bottom wall portion, and a pair of side wall portions. The wire connection portion includes a core wire crimping portion provided on one end side, and to be crimped onto a core wire of a wire, and a covering crimping portion provided on another end side, and to be crimped onto a covering of the wire, and integrally covers the core wire and the covering. In the core wire crimping portion before crimping, an interval between outer wall surfaces of the pair of side wall portions is widest at an end portion on the covering crimping portion side, and in the covering crimping portion before crimping, the interval is widest at an end portion on the core wire crimping portion side.

Crimp terminal and terminal crimping method

A female connector housing is provided with a plurality of terminal accommodating chambers. Each of the terminal accommodating chambers is provided, on its front face, with a terminal insertion opening through which a male terminal is to be inserted. Each of the terminal accommodating chambers is provided, on its rear face, with a wire withdrawal opening. In the terminal accommodating chamber which is intended to accommodate no terminal, there are provided a first shielding wall which surrounds an erroneous-insertion allowable space allowing the male terminal to be inserted erroneously and shields the interior of the erroneous-insertion allowable space and a second shielding wall for shielding the wire withdrawal opening.
