Press-clamping terminal
View Patent ↗A press-clamping terminal of the invention is press-fastened at its conductor-clamping portion on an outer periphery of a conductor part of a wire so as to be electrically connected to the conductor part. A plating layer is formed at least on an inner surface of the conductor-clamping portion for contact with the conductor part, the plating layer being harder than a passivation layer formed on a surface of the conductor part, and being excellent in electrical conductivity. With this construction, the hard plating layer fractures the passivation layer upon press-fastening of the conductor-clamping portion on the conductor part of the wire, thereby providing the good press-clamping condition in which any passivation layer, increasing the contact resistance, is not interposed between the press-clamping terminal and the conductor part.
1. A press-clamping terminal comprising:
a conductor-clamping portion for press-fastening an outer periphery of a conductor part of a wire for electric connection;
wherein a plating layer being excellent in electrical conductivity is formed at least on an inner surface of said conductor-clamping portion, and said plating layer is harder than a passivation layer formed on a surface of said conductor part;
wherein said plating layer is a nickel composite plating layer in which material molecular crystals, harder than said passivation layer formed on the surface of said conductor part, are dispersed in an eutectoid condition; and
wherein said plating layer is formed into a dull finish.
2. A press-clamping terminal according to claim 1 , wherein said plating layer has a Vickers hardness (Hv) of not smaller than 500.
