Authors have studied the influence on contact resistance by micro-oscillation to electrical contacts using hammering oscillation mechanism in the vertical direction. It was set that the oscillating acceleration was 150G, the frictional forces between male pins and female ones were 0.3N and each pin was connected respectively. When the measurement was carried out in the condition with 16 millions’ operations, the contact resistances fluctuated increasingly and the tendency of the fluctuation was different from each other. Therefore it was shown that there were the degradation tendencies of the connector depended upon the number and the amplitudes of the fluctuating contact resistance of pins. In addition it was shown that there were the similar tendencies in the initial term under 20,000 operations. Consequently it was suggested that a connector would be degraded by the influence of initial increasing contact resistance with a pin in the connector. And it was considered to be essential to analyze the time-sequential fluctuation of the contact resistance of each pin in a connector. |
