本発明は家庭用電熱機器に組み込まれるシーズ
ヒータユニツトに関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a sheathed heater unit incorporated in household electric heating equipment.
従来例の構成とその問題点
従来例の構成とその問題点を第１図を参照して
説明する。The structure of the conventional example and its problems The structure of the conventional example and its problems will be explained with reference to FIG.
１はシーズヒータ、２はシーズヒータ１の端子
であり、この端子２には角３をネジ締めするため

化をきたす等の品質上の問題を有するとともに、
リード金具４の接続工数や材料費から製品コスト
を高くする原因にもなつていた。 In the above configuration, not only is there a possibility that the square pottery 5 may be chipped when the corner pottery 5 is tightened by the lead fitting 4 and the corner 3, but also the sheathed heater 1 may be sealed due to the external tightening force of the corner 3. This causes quality problems such as cracks in the glass sealant (not shown) and deterioration of insulation resistance.
This also resulted in an increase in product cost due to the number of man-hours required to connect the lead fitting 4 and the cost of materials.
発明の目的
本発明は従来の問題を解消し、簡易な構成で品
質上の問題がなく、安価なシーズヒータユニツト
を提供するものである。OBJECTS OF THE INVENTION The present invention solves the conventional problems and provides a sheathed heater unit that has a simple configuration, has no quality problems, and is inexpensive.

The terminal of the sheathed heater and the corner can be firmly connected by inserting a ceramic corner and welding it to the corner at the notch.
実施例の説明
以下、本発明の一実施例について第２図および
第３図を参照して説明をする。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.
１１はシーズヒータ、１２はシーズヒータ１１

After inserting the terminal 12 into the insertion hole of the corner 14 with the square ceramic 13 interposed, the terminal 12 is inserted into the notch 14a provided in a part of the insertion hole.
The corner 14 and the terminal 12 are welded together by plasma welding or the like. In this way, the sheathed heater 1
1. After integrating the corner pottery 13 and the corner 14, the heater holder 15 is fitted onto the sheathed heater 11 and fastened to the corner pottery 13 to form a unit.
なお１６はシーズヒータの封口碍子である。 Note that 16 is a sealing insulator for the sheathed heater.
発明の効果
以上の説明から明らかなように、本発明のシー
ズヒータユニツトによれば、シーズヒータの端子

ツクが生じず絶縁劣化をきたす恐れは全くない。Effects of the Invention As is clear from the above explanation, according to the sheathed heater unit of the present invention, since the terminals and corners of the sheathed heater are directly welded together, the number of parts can be reduced, and the number of parts can be reduced. Since there is no screw tightening torque, the glass sealant of the sheathed heater will not crack, and there is no risk of insulation deterioration.
また、特に角の根本で溶接結合を行なつている
ために端子と角とが強固に接続され、シーズヒー
タユニツトを刃受けへ挿入する時にも外力による
変形等の支障はなく、その価値は大なるものであ
る。 In addition, since the welding is performed especially at the base of the corner, the terminal and the corner are firmly connected, and there is no problem of deformation due to external force when inserting the sheathed heater unit into the blade holder, making it very valuable. It is what it is.
