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.

摘要： A soldering iron is heated by an electric resistance heating element comprising a PTC thermistor having a positive temperature coefficient. The soldering iron has an elongated bit of copper with a cone shaped bit tip and a cylindrical back portion coupled with said bit tip. The back portion has a pair of arms and a slit between the arms for accepting the heating element with spring contact whereby the arms operate not only to transfer the heat to the tip, but also to fix the heating element in the slit tightly. The PTC thermistor is made mainly of Barium-titanate and has the additive of a small amount of calcium for improving the withstand voltage of the thermistor so that a commercial power supply can supply the power directly to the soldering iron. The total contact area S.sub.1 between the PTC thermistor and the back body being from 1.0 cm.sup.2 to 25 cm.sup.2 and the transverse cross sectional area S.sub.2 of the back body which contacts the thermistor being from 0.1 cm.sup.2 to 3.0 cm.sup.2.
摘要翻译：烙铁由具有正温度系数的PTC热敏电阻的电阻加热元件加热。烙铁具有细长的铜带，具有锥形钻头尖端和与所述钻头尖端连接的圆柱形后部。后部具有一对臂和两臂之间的狭缝，用于接受具有弹簧接触的加热元件，由此臂不仅将热量传递到尖端，而且还将加热元件紧密地固定在狭缝中。 PTC热敏电阻主要由钛酸钡制成，并且具有少量钙的添加剂，用于提高热敏电阻的耐受电压，使得商用电源可以直接将电力提供给烙铁。 PTC热敏电阻和后体之间的总接触面积S1为1.0cm 2〜25cm 2，与热敏电阻接触的背面的横截面积S2为0.1cm 2〜3.0cm 2。

摘要： A soldering iron is heated by electric resistance heating elements comprising barium titanate PTC thermistors. The soldering iron has an elongated copper bit with a cone shaped bit tip and an elongated back body having a generally rectangular cross section coupled to the bit tip. A pair of flat PTC thermistor heater assemblies sandwich the back body of the bit and are in thermal contact therewith. The heater assemblies are pressed against the back body of the bit with spring contact. A hand-grip is coupled with the bit. The total contact area S.sub.1 between the PTC thermistor heater assemblies and the back body is in the range from 1.0 cm.sup.2 to 25 cm.sup.2 and the transverse cross sectional area S.sub.2 of the back body is in the range from 0.1 cm.sup.2 to 3.0 cm.sup.2.
