【０００４】
本発明は上記の欠点を除くようにしたものである。
【０００５】
【課題を解決するための手段】
本発明の加熱炉用ヒータ端子装置は、炉壁を貫通して炉外に延びる炉内ヒーターの雄ねじ状ヒーター端子と、このヒーター端子に螺合した端子挟持用ナットと、上記ヒーター端子を取り囲むよう炉壁外面にその底面を固定したコップ状の絶縁キャップと、この絶縁キャップ内に形成される配線端子からのリード線を引き出すため上記コップ状絶縁キャップの側面に形成したリード線挿通孔と、を通り、外部に延びるヒーター端子と、このヒーター端子に螺合した、上記絶縁キャップの開口を覆ぐ絶縁カバー板と、この絶縁カバーを貫通して外部に延びる上記雄ねじ状ヒーター端子に螺合されるキャップ碍子とより成ることを特徴とする。
【０００６】
【発明の実施の形態】
以下図面によって本発明の実施例を説明する。
【０００７】
本発明においては図１及び図２に示すように、炉外に突出したヒーター端子４を取り囲むよう上記炉壁１の外面にコップ状絶縁キャップ１１の底面を固定し、このキャップ１１の側面にリード線挿通孔１２を形成し、上記コップ状絶縁キャップ１１内に配線端子部１０を形成せしめると共に上記コップ状絶縁キャップ１１の開口を、上記ヒーター端子４の貫通孔を有する絶縁カバー板１３で覆ぎ、この絶縁カバー板１３から外方に突出したヒーター端子４にキャップ碍子１４を螺合固定せしめる。
【０００８】
【発明の効果】
本発明の加熱炉用ヒータ端子装置は、上記のような構成であるから、配線端子部１０が外部に露出されず極めて安全であり、また、配線作業は絶縁カバー板１３を取り外してコップ状絶縁キャップ１１内で行なえるため部品の脱落も防ぐことができる等大きな利益がある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a heater terminal device for a heating furnace, and more particularly to a heater terminal device for a heating furnace that is safe.
[0002]
[Prior art]
3 to 5 show a conventional heater terminal device for a heating furnace, 1 is a furnace wall, 2 is a furnace heater, 3 is an end portion of a furnace heater 2 extending through the furnace wall 1 and extending outside the furnace, Reference numeral 4 denotes a male screw-shaped heater terminal extending outward from the end portion 3, reference numeral 5 denotes a Hakama insulator fixed to the outer surface of the furnace wall 1 so as to surround the heater terminal 4 protruding outside the furnace, and reference numeral 6 denotes an outer portion of the Hakama insulator 5. Cut grooves formed on both sides of the end portion, 7 is a lid of the Hakama insulator 5, 8 is a screw hole formed on the lid 7 and screwed to the heater terminal 4 protruding outside the Hakama insulator 5, 9 is the above 4 shows a nut for holding a lead wire (not shown) screwed to the male screw-shaped heater terminal 4.
[0003]
[Problems to be solved by the invention]
However, in the conventional heater terminal device for a heating furnace, the wiring terminal portion 10 including the heater terminal 4 and the lead wire holding nut 9 is exposed to the outside through the large cut groove 6 of the Hakama insulator 5. There was a drawback lacking in sex.
[0004]
The present invention has been made to eliminate the above disadvantages.
[0005]
[Means for Solving the Problems]
Furnace heater terminal apparatus of the present invention includes a male screw-shaped heater terminals furnace heater Ru extending out of the furnace through the furnace wall, and a terminal clamping nut screwed into the heater pin, the heater terminal A cup-shaped insulating cap whose bottom is fixed to the outer surface of the furnace wall so as to surround it, and a lead wire insertion hole formed on a side surface of the cup-shaped insulating cap for drawing out a lead wire from a wiring terminal formed in the insulating cap. , A heater terminal extending to the outside, an insulating cover plate screwed to the heater terminal, covering an opening of the insulating cap, and screwed to the male screw heater terminal extending through the insulating cover to the outside. And a cap insulator.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0007]
In the present invention, as shown in FIGS. 1 and 2, the bottom surface of the cup-shaped insulating cap 11 is fixed to the outer surface of the furnace wall 1 so as to surround the heater terminal 4 protruding out of the furnace. A wire insertion hole 12 is formed, the wiring terminal portion 10 is formed in the cup-shaped insulating cap 11, and the opening of the cup-shaped insulating cap 11 is covered with an insulating cover plate 13 having a through hole for the heater terminal 4. Then, the cap insulator 14 is screwed and fixed to the heater terminal 4 projecting outward from the insulating cover plate 13.
[0008]
【The invention's effect】
Since the heater terminal device for a heating furnace according to the present invention is configured as described above, the wiring terminal portion 10 is not exposed to the outside and is extremely safe. In addition, the wiring work is performed by removing the insulating cover plate 13 and removing the cup-shaped insulation. Since it can be carried out in the cap 11, there is a great advantage in that parts can be prevented from falling off.
