本発明は金属パイプの一側開口から二本の電極
線を突出したカートリツジヒータに関し、特に二
本の電極線の絶縁距離を確保しようとするもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cartridge heater in which two electrode wires protrude from an opening on one side of a metal pipe, and is particularly intended to ensure an insulation distance between the two electrode wires.
従来、この種のカートリツジヒータは、製造過
程において二本の電極線やこの電極線に接続され
たリード線にテンシヨンが加わり、電極線の根元
やリード線との接続部において断線したり、接触
したりする危険があつた。 Conventionally, in the manufacturing process of this type of cartridge heater, tension is applied to the two electrode wires and the lead wires connected to these electrode wires, causing disconnection or contact at the base of the electrode wires or the connection with the lead wires. There was a risk of doing something like that.
本発明は上記従来のカートリツジヒータの欠点
を解消するもので、以下に本発明の実施例につい
て添付図面を参照して説明する。 The present invention solves the above-mentioned drawbacks of the conventional cartridge heater, and embodiments of the present invention will be described below with reference to the accompanying drawings.

チユーブ１３の一部を覆つている。 In the figure, 1 is a metal pipe with one side closed. 2 is a core formed by sintering magnesia powder, through which two electrode wires 3 and 4 are passed, and a heating wire 5 connected to the electrode wires 3 and 4 is wound around it, and a metal pipe 1 is formed as a core unit. is inserted into. 6 is an insulating powder filled in the metal pipe 1, and 7 is a heat-resistant insulating sealing material for sealing the opening of the metal pipe 1. Note that the amount of protrusion of the electrode wires 3 and 4 from the end surface of the sealing material 7 is different. 8 is a connecting tube that connects the electrode wire 3 with a short protrusion amount and the lead wire 9, and 10 is a connecting tube that connects the heating wire 4 with a long protrusion amount and the lead wire 11. 12 is a heat-resistant insulating tube that covers the exposed portion of the electrode wire 3, the connecting tube 8, and a portion of the lead wire 9; 13 is the exposed portion of the electrode wire 4, the connecting tube 10, a portion of the lead wire 11, and a heat-resistant insulating tube 12; This is a heat-resistant insulating tube that covers part of the lead wire 9. 14 is a metal protection pipe joined near the end of the metal pipe 1, and covers a part of the heat-resistant insulating tube 13.

のである。 As is clear from the above configuration, according to the present invention,
The two electrode wires connected to the heating wire and protruding from the opening of the metal pipe and the lead wires connected to each electrode wire are connected at different positions, and one of these connection positions is heat-resistant insulated. In addition to covering these connection points with a protective pipe connected to the metal pipe, the two electrode wires of different polarities do not touch or come close to each other, and the insulation distance is reduced. It has a simple structure, and the presence of the heat-resistant insulating tube reliably prevents disconnection accidents, and the connection volume at the connection between the electrode wire and lead wire can be reduced. It has excellent effects.
