本発明は、とくに接地抵抗器や起動用抵抗器として用い

あった。Conventionally, in resistors that require large capacity resistance, a grid resistor or a metal resistor made of high-resistance metal is generally used as the resistor, and the resistance value fluctuates greatly due to temperature changes. It became unstable, and the molding, processing, and holding device required to construct it as a resistor were troublesome.
本発明はこのような抵抗体を、第２酸化錫（８ｎ０２）
と３酸化７ｙチモ−”−（Ｓｂ２０５）を主体とし、酸
化亜鉛（ＺｎＯ）を添加したセラミックス抵抗体で構成
することによって、従来の欠点を解消したものである。The present invention provides such a resistor using dinic tin oxide (8n02).
The drawbacks of the conventional resistor have been overcome by constructing a ceramic resistor mainly composed of 7y thimo-trioxide (Sb205) and zinc oxide (ZnO) added thereto.

フィンを加えて必要形状たとえば丸棒状、屈曲状に圧縮
成形し。This ceramic resistor contains 2 to 10 mol% of 8n02.
Mix 5b2o3 thoroughly and bake at 800 to 1000°C for 1 to 2 hours to form a granular baked product.
~5 mol % of ZnO is mixed and pulverized, water and a small amount of polyvinyl acetate 6 or paraffin are added as a binder, and the mixture is compression molded into a desired shape, such as a round rod shape or a bent shape.
１ｏｏｏ〜１４００°Ｃで約２時間焼成して得られる。It is obtained by firing at 100°C to 1400°C for about 2 hours.
この成形時に両端部の少なくとも表面に導電粉を混入し

さくシ、端子を構成させることができる。By mixing conductive powder into at least the surfaces of both end portions during this molding, the contact resistance at these portions can be reduced to form a terminal.

りつけである。４は接続金具、５は端子である。Figures 1 and 2 show an example of a resistor constructed using this resistor, where 1 is a resistor element formed into a straight round bar and arranged in four pieces using 0-asbestos paper (not shown). The clamp metal fittings 2 are used to clamp the metal fittings via the clamp metal fittings 2, and both ends of the clamp metal fittings are attached to the frame 8. 4 is a connecting fitting, and 5 is a terminal.
抵抗体素子１は機械的強度および接触抵抗が大きく、熱
膨張が小さいためクランプ金具２は石綿紙などの簡単な

てよい。Since the resistor element 1 has high mechanical strength and contact resistance and low thermal expansion, the clamp fitting 2 may be attached via a simple insulation such as asbestos paper without considering axial expansion.

しく簡単にし得る効果がある。As described above, since the resistor of the present invention is composed of a sintered body mainly composed of 5n02 and 5b2o5 with the addition of zlo, the shape of the resistor can be formed arbitrarily, and the resistance value of the element itself is large. A small, lightweight, large-capacity resistor can be constructed, and since the contact resistance of the element is large and thermal expansion deformation is small, the support structure when assembled as a resistor can be significantly simplified.
