Electric wire terminal connection structure and intermediary cap used for the same

摘要

An electric wire terminal connection structure includes an electric wire including a core made of a metallic material and an insulation layer covering the core, a terminal fitting attached to a terminal of the electric wire and made of a metallic material other than the metallic material of the core, and an intermediary cap to be crimped to the core by the terminal fitting and to cover an exposed portion of the core exposed by removing the insulation layer at the terminal of the electric wire. The intermediary cap has conductivity and is made of a metallic material having a value of a standard electrode potential between that of the core and that of the terminal fitting.

1. An electric wire terminal connection structure comprising:
an electric wire comprising a core made of a metallic material and an insulation layer covering the core; a terminal fitting configured to be attached to a terminal of the electric wire and made of a metallic material other than the metallic material of the core; and an intermediary cap configured to be crimped to the core without a water-proof measure between the intermediary cap and the core by the terminal fitting and to cover an exposed portion of the core exposed by removing the insulation layer at the terminal of the electric wire, the intermediary cap having conductivity and made of a metallic material having a value of a standard electrode potential between a value of a standard electrode potential of the core and a value of a standard electrode potential of the terminal fitting.
