A male screw is formed on a lower surface of the upper stirring bar(220). A first screw thread(225) is formed on the outer periphery of the lower portion of the upper stirring bar(220). A lower stirring bar(260) made of carbon has a female screw(265) formed on upper surface thereof. A screw thread(261) for a second connecting is formed on upper outer periphery surface of the lower stirring bar(260). A thread groove(245) for engaging with the first/second screw threads is formed on the inner periphery surface of a connecting ring(240). A platinum coating is covered on the outer periphery surface of the lower stirring bar(260) and the connecting ring(240). Therefore, the connecting ring double connects the upper stirring bar(220) and the lower stirring bar(260).

Abstract: PURPOSE: An installation structure for the connector of a vehicle is provided to couple the connector with the installation portion of an opposite connector with one operation. CONSTITUTION: An installation portion(12) of an opposite connector(10b) is composed of a rubber seal groove, a ring spring groove and an airtight rubber seal. The rubber seal groove is formed on the inner diameter of the installation portion and the rubber seal of the connector is inserted into the rubber seal groove. Thus, the connector is coupled with the opposite connector with one operation. A ring spring is tightly compressed and inserted into the installation portion. The rubber seal of the connector prevents impurities from invading into the installation portion.
