It is characterized by:
以下本発明の一実施例を示す第１図により説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be explained below with reference to FIG.

いる。The band-shaped heating element 1 is a band-shaped resistance heating element 2 formed of crystalline plastic mixed with conductive powder such as carbon blank, and electrode wires 4.4 such as copper wires are embedded therein. A heat-resistant insulator 3 is placed over the circumference of the heating element 2.

してなるものである。At the end of the band-shaped heating element 1, a necessary and sufficient length of the band-shaped resistance heating element 2 and the insulator 3 is peeled off to expose electrode wire ends 4a, 4a of a predetermined length. Heat-resistant insulating sleeves 9, 9 are placed over the exposed portions of the sections 4a, 4a from the end of the band-shaped resistance heating element 2 to slightly before the end. Crimp terminals 11.11 having insulators 10.10 are crimped and attached to the ends of the exposed electrode wire ends 4a, 4a.

。The insulator 10° IO of the crimp terminal 11.11 is preferably placed over the end circumference of the insulating sleeves 9, 9 to wipe out the exposed live portion between the terminal 11 and the insulating sleeve 9.
そして絶縁スリーブ９，９と、帯状発熱体１の絶縁体３

のである。Then, the insulating sleeves 9, 9 and the insulator 3 of the band-shaped heating element 1
The cut end of the strip-shaped resistance heating element 2 is insulated by covering the cut end with a heat-resistant insulating cap 12.

By covering it, a completely waterproof structure can be achieved.

心配はないものである。A feature of the self-regulating heater is that the plastic containing conductive powder is the heating element, and the Nh wire 4 serves as the power supply line to the heating element. Based on my experience, if the exposed length of 4a is 30 pieces or more,
Even if the electrode wire 4 is directly introduced and connected to an electric device such as an electric circuit breaker or an electromagnetic contactor on the power supply side, there is no need to worry about heating the electric device, unlike heating wires that use metal resistors. It's something that doesn't exist.
従って、前述した端末施工を行うことによって電気機器
への組み込みが給電ケーブルを用いずに行えるものであ
る。Therefore, by performing the above-described terminal construction, it is possible to incorporate the device into electrical equipment without using a power supply cable.

等その実用的効果は甚大である。As explained above, according to the power feeding terminal section of the present invention, the insulating treatment that is essential to the band-shaped heating element and the connection part for obtaining the feeding end formed at the end of the electrode wire in the band heating element are provided. Since the electrode wire is separated from the electrode wire, it can be made sufficiently smaller than the conventional terminal where they are concentrated. Since it is used as a lead wire, it can be connected to the power supply section without using a power supply cable, and the practical effects include reducing the number of connection points and making installation easier. It's huge.
