Abstract

Disclosed is a connector contact material that has a small friction coefficient, requires a small insertion force, and moreover does not raise contact resistance while maintaining the properties and insertion operability as a connector. The connector contact material has a coating film comprising the mixture of fluoric resin particles and fluoric oil on the surface of a substrate, wherein the thickness of the coating film is 0.2 to 0.5 μm, and the proportion of the fluoric resin particles to the total amount of the fluoric resin particles and the fluoric oil in the coating film is 20% to 40% in mass, and thereby the connector contact material has a small friction coefficient, requires a small insertion force, and moreover does not raise contact resistance.

Claims

1. A connector contact material having a coating film comprising the mixture of fluoric resin particles and fluoric oil on the surface of a substrate, characterized in that:

the thickness of the coating film is 0.2 to 0.5 μ

m; and

the proportion of the fluoric resin particles to the total amount of the fluoric resin particles and the fluoric oil in the coating film is 20% to 40% in mass.

2. The connector contact material according to claim 1, wherein the fluoric oil is perfluoropolyether type oil.

3. The connector contact material according to claim 1, wherein the fluoric resin particles are perfluoropolyether type particles.

4. The connector contact material according to claim 1, wherein the conductive substrate is made of copper or copper alloy.

5. The connector contact material according to claim 1, wherein the connector contact material is used for multipole terminals.
