We have developed the mechanism which gives vibration to electrical contacts and studied the influences of a micro-oscillating on electrical ones. Over 5 millions on operation’s numbers of hammering in this mechanism, contact resistance was increasing in value. Over 5.6 millions, the measured values of the contact resistance often exceeded 100[Ω] . And over 9.9 millions, they showed vibrationally between 100[Ω] at minimum of values and 400[Ω] at maximum of values. On the other hand, we have developed the mechanism for trial which gives sliding to electrical contacts, and showed the degradation phenomenon of electrical ones by influences of repeated sliding operations. Over 0.03 millions on operation’s numbers of sliding in this mechanism, contact resistance was increasing in value, and they showed vibrationally between 20[Ω] at minimum of values and 250[Ω] at maximum of values. Although the two mechanisms were different each other in the operational methods and numbers, they were similar to each other on the oscillational phenomenon generated of electrical contacts. |
