Abstract

A wire with corrosion-resistant terminal ( 60 ) includes an aluminum wire ( 40 ) and a corrosion-resistant terminal ( 10 ) is formed from a base material made of copper alloy. The terminal ( 10 ) includes a wire connecting portion ( 30 ) connected to an end of the aluminum wire ( 40 ). The copper alloy exposed on an end part of the wire connecting portion ( 30 ) is covered with an anticorrosive ( 50 ). End parts of the base material in the wire connecting portion ( 30 ) face inward on an upper surface of the wire connecting portion ( 30 ) while winding around the end of the aluminum wire ( 40 ). A storage portion ( 33, 34 ) is surrounded by the end parts of the base material, and the anticorrosive ( 50 ) is stored in the storage portion ( 33, 34 ) in a region (R 1, R 2 ) narrower than a maximum width region (W 1, W 2 ) on the upper surface of the wire connecting portion ( 30 ).

First claim

1 . A wire with corrosion-resistant terminal, comprising:
a coated wire having a core covered with an insulation coating; and a corrosion-resistant terminal formed by applying bending to a piece punched out from a base material made of a metal different from the core and includes a wire connecting portion connected to an end of the coated wire and metal exposed on an end part of the base material of the wire connecting portion being covered with an anticorrosive, wherein two 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 ends of the coated wire, a storage portion being surrounded by the end parts of the base material, and the anticorrosive is stored in the storage portion and arranged in a region narrower than a maximum width region on the upper surface of the wire connecting portion.

2 . The wire with corrosion-resistant terminal of claim 1 , wherein the wire connecting portion includes a wire barrel to be crimped to the core and an insulation barrel to be crimped to the coating, and the storage portion includes a front storage portion formed to include a front end part of the wire barrel and a rear storage portion formed to include a rear end part of the wire barrel.

3 . The wire with corrosion-resistant terminal of claim 2 , wherein a bell-mouth inclined upwardly toward a back side is formed on a rear end part of the wire barrel and the rear storage portion extends backward from the end part of the base material exposed on a rear end of the bell-mouth.

4 . The wire with corrosion-resistant terminal of claim 3 , wherein the coated wire is a wire including a core made of aluminum or aluminum alloy, whereas the corrosion-resistant terminal is formed of the base material made of copper or copper alloy.

5 . The wire with corrosion-resistant terminal of claim 1 , wherein the coated wire is a wire including a core made of aluminum or aluminum alloy, whereas the corrosion-resistant terminal is formed of the base material made of copper or copper alloy.
