摘要： A PTC heating device which is widely applicable as a heating source to a variety of electronic apparatuses such as an electronic mosquito destroyer an electronic jar and the like. The PTC heating device includes a porcelain casing in which an electrode structure comprising a PTC thermistor having electrodes arranged on both surfaces thereof and two electrode plates interposing the thermistor therebetween is received in a manner such that terminals of the electrode plates is downwardly led out through the porcelain casing. The PTC heating device also includes a heat radiating plate arranged through an insulating plate on the electrode structure and provided at flanges thereof with a plurality of holding pawls which are located at positions apart from the terminals of the electrode plates on a bottom surface of the porcelain casing to securely hold the heat radiating plate and the porcelain casing together and ensure an adequate insulating distance between the holding pawls and the terminals. The electrode plate arranged on the PTC thermistor is provided with a narrow section which is adapted to be fused due to an overcurrent flowing therethrough. The PTC heating device also includes various mechanisms in relation to such an overcurrent fusion function.
