| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Silicone contamination is one of well-known reasons of contact failures. It has been reported that siloxane component emitted from silicone-including polymeric materials is dissolved and converted into SiO2 due to arc discharges upon relay operations, deposited onto contact surfaces, resulting in a significant increase in contact resistance. In this paper, a new acryl-based polymeric material (containing no silicone components) is evaluated with respect to its effects on contact resistance characteristics of relay contacts. More specifically, a commercially-available mechanical relay (AgSnIn contacts) is sealed into a can with the acryl-based polymeric material, and placed in a heating chamber to operate 40,000 break operations of an inductive load current (DC14V-1A and DC20V-1.5A) under each of 80 ºC and 120 ºC conditions. Contact resistance is measured over the operations. The same experiments are also conducted with two types of specific silicone-containing polymeric materials, and the experimental results are compared. As a result, relays sealed with the acryl-based polymeric material show no significant increases in contact resistances, while relays sealed with each of the silicone-containing polymeric materials show remarkable increases in contact resistances, especially under the 120 ºC condition, even in the case where the material is of a counter-measure type against contact failures. |
