【考案の詳細な説明】
本考案はリード線接続装置に関するものであ
り、加熱物に接続されるリードを熱から保護する
装置を提供することを目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lead wire connecting device, and an object of the present invention is to provide a device that protects a lead connected to a heated object from heat.
たとえば高周波加熱調理器において、電熱加熱

ド線５を接続する必要がある。 For example, some high-frequency cooking devices are equipped with an electric heater inside the heating chamber to enable electric heating. In FIG. 1, 1 is a heating chamber, 2 is a high frequency oscillator, and 3 is a heater. This heater 3
It is necessary to connect a lead wire 5 to supply power as shown in FIG.
ヒータ３が４本存在する場合、従来は第２図に

感電事故につながる恐れもあつた。 When there are four heaters 3, conventionally the lead wire 5 is connected to the terminal screw 6 of each heater 3 using a lug plate 7 and a nut 8, as shown in FIG. However, the heater generates heat, so if you use it for a long time,
There was a risk that the terminal screw 6, lead wire 5, etc. would be thermally deteriorated due to heating, and the caulked portion would become loose, resulting in poor continuity. Also, lead wire 5
There was also a risk that the vinyl coating would melt and touch the outer wall of heating chamber 1, leading to an electric shock accident.
本考案はこのような欠点を改良したものであ
り、以下本考案の一実施例につき図面を用いて説
明する。 The present invention improves these drawbacks, and one embodiment of the present invention will be described below with reference to the drawings.
第３図に示すように加熱室１に複数個のヒータ

で固定する。いずれの短絡板も加熱室１の壁面か
らは空隙１５を設けて絶縁している。 As shown in FIG. 3, a plurality of heaters 3 are arranged in the heating chamber 1. Each heater 3 is provided with a plurality of heater terminal screws 6, 9, 11, and 12. Fix the metal shorting plate 10 connecting the heater terminal screws 6 and 9 with nuts, and connect the outer pair of heater terminal screws 1.
A metal shorting plate 13 connecting 1 and 12 is fixed with a nut. Both short circuit plates are insulated from the wall surface of the heating chamber 1 by providing a gap 15.
上記短絡板１３は上記短絡板１０と接触しない
ようコ字状にしておけばよい。 The shorting plate 13 may be formed into a U-shape so as not to come into contact with the shorting plate 10.
リード線５は上記短絡板１０にビスで接続さ
れ、リード線１４は短絡板１３にビスで接続され
る。 The lead wire 5 is connected to the shorting plate 10 with a screw, and the lead wire 14 is connected to the shorting plate 13 with a screw.
このようにリード線を直接端子ビスに接続せず
短絡板を介しているため短絡板は放熱板としての
効果も奏し、ヒータから伝達してくる熱は放散さ
れリード線にはほとんど伝わることがない。また
各接続部分も温度が上昇することはなく、接続劣
化も最小限におさえることができ寿命を長くする
ことができるものである。 In this way, the lead wire is not directly connected to the terminal screw, but via the shorting plate, so the shorting plate also acts as a heat sink, and the heat transferred from the heater is dissipated and almost never reaches the lead wire. . Furthermore, the temperature of each connected portion does not rise, and connection deterioration can be minimized, resulting in a longer service life.
以上のように本考案によれば、加熱物同士を短
絡板で接続し、この短絡板にリード線を接続する
ようにしたので、接続部分に熱劣化が生せず寿命
を長くすることができるものである。また短絡板
は複数個のヒータの端子相互間に設ける構成であ
るので端子が短絡板を保持すると共に端子間の導
通接続の役目も兼ねるので短絡板を保持するため
の絶縁体を別に設ける必要もなく、極めて簡単な
構成でありながら複数個のヒータの接続が確実に
できる。端子間を結ぶ短絡板は加熱室壁面から空
隙を設けて設置できるので加熱室壁面との絶縁が
確実にとれ、安全であると共に加熱室壁面が高温
になつても絶縁劣化の心配もなく、この面からも
安全である。複数個のヒータを短絡板で結ぶ構成
であるので短絡板によりヒータ相互が保持される
のでより確実な固定ができる。 As described above, according to the present invention, the heated objects are connected to each other by a short circuit board, and the lead wire is connected to this short circuit board, so that thermal deterioration does not occur at the connected part and the lifespan can be extended. It is something. In addition, since the shorting plate is installed between the terminals of multiple heaters, the terminal holds the shorting plate and also serves as a conductive connection between the terminals, so there is no need to separately provide an insulator to hold the shorting plate. Although the configuration is extremely simple, multiple heaters can be connected reliably. The short-circuit plate connecting the terminals can be installed with a gap from the heating chamber wall, so insulation from the heating chamber wall is ensured, and it is safe and there is no need to worry about insulation deterioration even if the heating chamber wall gets hot. It is safe from both sides. Since a plurality of heaters are connected by a short circuit plate, the heaters are mutually held by the short circuit plate, so that more reliable fixing can be achieved.
電源リード線はヒータを結ぶために分岐するよ
うなことも不要であり、簡単で安価になるだけで
なく、電源リード線が高温の加熱室壁面に触れて
地絡事故を起す危険もなくなる。 There is no need for the power lead wire to branch to connect the heater, which not only makes it simpler and cheaper, but also eliminates the risk of the power lead wire touching the high-temperature heating chamber wall and causing a ground fault.
