IPC: F24C7/02
Filed: 1982-09-10
Abstract: PURPOSE:To avoid the imposition of adverse force on a receptacle for thereby accomplishing the stable rotation of receptacle, by arranging such that contactors are opposing each other around the receptacle to overcome a pressing force. CONSTITUTION:A contactor 10 is arranged over the outer periphery of receptacle as opposed to each other, while a retaining member 11 is provided with the same positional relationship as the above. When a pressing force is given to a contactor 10 by utilizing the spring force of retaining member 11, the moment Fo of retaining member 11 is divided into moments F1 and F2 by a symmetrical axes X-X and Y-Y passing through the center of receptacle 8. Since the contactor 10 for opposite poles of thermistor is arranged as opposed to each other, divided moments F1 and F2 respectively act as an opposing force and accordingly the moment Fo of retaining member 11 is obtained entirely as the pressing force against the receptacle 8. In this manner, while the moment Fo of retaining of retaining member 11 is obtained entirely as the pressing force against the receptacle 8, the receptacle 8 can withhold its stable positional relationship without the chance of being displaced by a biasing force.
