PTC THERMISTOR DEVICE

摘要

The workability is improved with respect to a PTC element attaching structure at the time of incorporating a PTC element in a case so that the surfaces of electrodes can be prevented from being scratched and, at the same time, the position stability of the element can be improved. An insulating guide section which guides the vicinity of one end section of a PTC element (48) is provided in a case (40), and the electrode is elastically held between first and second terminals (44 and 45) by pressing the terminal (44) against one surface of the electrode near the other end section of the element (48) and the terminal (45) against the other surface of the electrode near the central part of the element (48). The guide section is constituted of first and second guide sections (41 and 42) which are opposed to each other on both sides of the element (48), and the element (48) is held by one of the guide sections (41 and 42) and the terminals (44 and 45). In addition, hook sections (46 and 47) are provided so as to hook the electrode to the vicinity of the contact section of either one of the terminals (44 and 45) with a jig.
