One of the tipical ways of conecting and tightning use a scrwe. A malfanction doesn't happen if an appropriate connection can be done. But, deterioration by the moisture and Pollution make the contact load of the connection spot in the direction of the decrease by the long use in the connection spot. In such a case, it knows that the occurrence of heat generation at the connection well. Generaly the heat is not know that a local heat generation with high temperature (about more than 1000℃) follows the fact the heat generation. We name the generation of heat phenomenon "a hot zone phenomenon", and we are studying it. A connection spot becomes high temperature in the long time while current is being supplied electric power once hot zone phenomenon occurs. These things cause the mis-operation of the machine and the cause of the trouble. In the worst case, A hot zone phenomenon causes a fire by the condition. it is the report that it is stuck independently and it has it about each of the various phenomena about the hot zone phenomenon. Independent phenomena are two of the electric character with the visual observation. It has it about the method to choose the combination of the connection part metal as the optimum. The combination of the metal is applicable to which circuit of the D.C. circuit, the A.C. circuit and the high frequency circuit as well. It will be able to be helped in this report's saving it from many electric accidents and the trouble.
