Authors have studied the influence on contact resistance by actual micro-oscillation to electrical contacts using some oscillating mechanisms in the vertical direction. In this paper, first, the authors improved the mechanism in some points. Second, they examined the dynamical properties of the refined mechanism and confirmed that the mechanism was able to give micro-reciprocating slides to the electrical contacts. Finally, they analyzed the characteristic degradation phenomena of real electrical contacts caused by the mechanism. Consequently the natural frequencies and damping ratio of the mechanism with connectors were estimated and it was shown that there were lower limits in the reciprocating-sliding amplitudes of the mechanism causing degradation of electrical contacts. |
