In the figure, 1 is a bottomed cylindrical metal pipe with one end sealed, 2 is a heating wire inserted into the metal pipe 1, 3 is electrical insulation powder filled in the metal pipe 1, and 4 is a heating wire 2 Metal pipe 1 connected to both ends of
5 is a metal tube connector into which the protruding end of the electrode wire 4 is inserted; 6 is a lead wire inserted into the other end of the metal tube connector 5; 7 is a metal pipe 1; 8 is a heat-resistant glass braided coating tube that covers the metal pipe connector. This conventional cartridge heater is installed in a hole in a mold and when removed, bending stress is repeatedly applied to the electrode wire 4, vibration is applied during mounting, or the electrode wire is bent. 4
There was a drawback that the wire was disconnected.
本考案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、本考案の実施例につい
て、第２，３図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 FIGS. 2 and 3.
なお、第２，３図において、第１図と同一構成
物に対し、同一番号を付し、説明を省略する。 In addition, in FIGS. 2 and 3, the same components as in FIG. 1 are given the same numbers, and explanations thereof will be omitted.

金属管接続子５とリード線６の接続はスポツト溶
接接合、圧着接合により行われている。 In FIG. 2, the metal tube connector 5 is partially inserted into the open end of the metal pipe 1, for example, by about 5 to 15 mm, and the insertion joint end of the electrode wire 4 into the metal tube connector 5 is inserted into the metal pipe 1. While located inside the pipe 1, a portion thereof is embedded in a sealant 7 made of a heat-resistant insulating material. The metal connector 5 and the electrode wire 4, and the metal tube connector 5 and the lead wire 6 are connected by spot welding or pressure bonding.
上記構成において、リード線６に曲げ応力等が

もよい。 In the above configuration, even if bending stress or the like is applied to the lead wire 6, since the strength of the metal tube connector is high, the electrode wire 4 will not be directly bent and disconnected, and therefore the heating wire 2 The electrical circuit will not be cut off. Incidentally, as shown in FIG. 3, the sheathed portion of the lead wire 6 may be inserted and connected to the metal tube connector 5.

である。 As described above, according to the present invention, the metal tube connector is provided with a metal tube connector in which the electrode wires connected to both ends of the heating wire are inserted and bonded to one end, and the lead wire is inserted and bonded to the other end. A part of the lead wire is embedded in a sealing agent that seals the opening of the bottomed cylindrical metal pipe with the inserted and joined end of the electrode wire located inside the metal pipe, so the lead wire is subject to bending stress and vibration. To provide a cartridge heater with a long life, since the electrode wire will not be directly bent and disconnected even if the heating wire is added, and as a result, the electric path to the heating wire will not be cut off. It is something that can be done.
