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 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

The present invention concerns a corrosion-resistant terminal () before being crimped to an aluminum wire () in which a core () is covered with a coating () and the corrosion-resistant terminal () includes a wire barrel () to be crimped to the core () exposed by removing the coating (), an insulation barrel () to be crimped to the coating (), and an anticorrosive () applied in advance to a surface of the insulation barrel () to be held in contact with the coating (). According to such a configuration, since the anticorrosive () is applied in advance to the surface of the insulation barrel () to be held in contact with the coating () of the aluminum wire (), the anticorrosivecan be filled between the insulation barrel () and the coating () of the aluminum wire () when crimping is performed.

Corrosion-resistant terminal, wire with corrosion-resistant terminal and method for producing wire with corrosion-resistant terminal

A wire with corrosion-resistant terminal () includes an aluminum wire () and a corrosion-resistant terminal () is formed from a base material made of copper alloy. The terminal () includes a wire connecting portion () connected to an end of the aluminum wire (). The copper alloy exposed on an end part of the wire connecting portion () is covered with an anticorrosive (). End parts of the base material in the wire connecting portion () face inward on an upper surface of the wire connecting portion () while winding around the end of the aluminum wire (). A storage portion () is surrounded by the end parts of the base material, and the anticorrosive () is stored in the storage portion () in a region (R, R) narrower than a maximum width region (W, W) on the upper surface of the wire connecting portion ().

Wire with corrosion-resistant terminal

A terminal () of a terminal-attached wire (), in which the terminal () is connected to an end portion of a wire () and the end portion is sealed by a heat shrinkable tube (), includes a terminal connecting portion () to be connected to a mating terminal, a wire connecting portion () to be connected to the end portion of the wire () and a coupling portion () coupling the terminal connecting portion () and the wire connecting portion () An opening end (A) of the heat shrinkable tube () is mounted on the coupling portion (), and a draining portion () for preventing adhering water from running down to the opening end (A) is provided on a side closer to the terminal connecting portion () than the opening end (A).

Terminal-attached wire and terminal

A relay terminal () made of copper or copper alloy and configured to join an aluminum wire () and a copper wire () by being electrically connected to the aluminum wire () and the copper wire () includes a first barrel portion () to be caulked and crimped to an aluminum core () of the aluminum wire () made of aluminum or aluminum alloy, which is a metal different from copper or copper alloy constituting the relay terminal (), a second barrel portion () to be caulked and crimped to a copper core () of the copper wire (), a bottom plate () configured to link the first barrel portion () and the second barrel portion (), and a projecting portion () (water drainage portion ()) provided on the bottom plate () and configured to restrict the intrusion of water from the second barrel portion () toward the first barrel portion ().

Multiple wire connecting terminal

Electrical connector housing

An electric wire with terminal includes an electric wire covering an outer periphery of a core wire with an insulating coating and a female terminal. The female terminal includes: a wire barrel having a bottom plate on which the core wire is placed and crimped onto the core wire; a groove portion extending from the bottom plate in a direction in which the core wire extends and whose surface on the side where the core wire is placed is bent into a concave shape. The groove portion has a water blocking wall molded by synthetic resin. The water blocking wall is provided to fill the inside of the groove portion. A region extending from the water blocking wall to the end of the insulating coating is covered with a water blocking coating, and the inner surface of the water blocking coating is in close contact with the water blocking wall.

Electric wire with terminal and connector

A female terminal fitting () is to be crimped to a wire including a core () formed by plural strands () and includes a bottom plate () on which the core () is to be placed, and a pair of crimping pieces (L,R) connected to the bottom plate () and to be crimped to the core () in such a manner as to embrace the core () placed on the bottom plate (). Butting parts of the respective crimping pieces (L,R) are formed with a thinning portion (), and a corner portion () is formed by deforming the thinning portion () when the respective crimping pieces (L,R) are crimped to the core (). Accordingly, a clearance formed at the butting parts of the respective crimping pieces (L,R) can be made smaller than in the case where the thinning portions () are not provided.

Terminal fitting

A terminal fitting () is crimped to an aluminum wire including a core () formed by putting a plurality of strands () together. The terminal fitting () includes a bottom plate () on which the core () is placed, and two barrel pieces (L,R) connected to the bottom plate () and crimped to the core () so as to embrace the core () placed on the bottom plate (). Overlapping portions (L,R) are formed on tip parts of the respective barrel pieces (L,R) by folding a plate material forming the barrel pieces (L,R) to overlap layers of the plate material. The overlapping portions (L,R) contact each other without intruding between the strands () when the respective barrel pieces (L,R) are crimped to the core (). The terminal fitting () eliminates breakage of the core () and is less affected by spring back.

Crimp type terminal fitting

An object of the present invention is to provide a terminal fitting with improved waterproof property. A terminal fitting () includes a box-shaped main portion (), barrel portions () to be crimped and connected to a core () at an end portion of a wire (), a waterproof wall () to be mounted between the barrel portions () and the main portion () to partition between them in a liquid-tight manner, a restricting portion () configured to restrict a movement of the waterproof wall () toward the main portion () by coming into contact with the waterproof wall () from the main portion () side and a heat shrinkable tube () to be held in close contact with the barrel portions () and the waterproof wall () while surrounding the core ().

A housing () includes a cavity () into which a terminal fitting () fixed to an end portion of a wire () is to be inserted from behind. The terminal fitting () includes a barrel () to be fixed to a core () of the wire () and a contact part between the barrel portion () and the core () of the wire () is covered by a waterproof member (). Recesses () that widen the width of the cavity () are formed in parts of peripheral walls () of the cavity () corresponding to the barrel () of the terminal fitting ().
