Description
【発明の詳細な説明】
本発明は過電流が流れて発熱したとき、または外部加熱
されたとき回路遮断する熱応答スイッチに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thermally responsive switch that interrupts a circuit when an overcurrent flows and generates heat or when external heating occurs.
従来、低融点金属材料或いは非低融点金属材料を使用し
たヒユーズ、加熱防止用の温度ヒユーズ等が回路遮断用
として知られている。しかしながらこの従来のヒユーズ
では溶断すれば再度使用することができない。Conventionally, fuses made of low-melting point metal materials or non-low-melting point metal materials, temperature fuses for preventing heating, and the like are known for circuit-breaking purposes. However, once this conventional fuse is blown, it cannot be used again.
本発明はこれを形状記憶合金を用いて再使用できるよう
に構成したものである。The present invention uses a shape memory alloy to configure this so that it can be reused.
図において１及び２は形状記憶合金で形成した導体で、
何れも支持部３，４の先に固定され、先端１ａ、 ２ａ

接着するか、樹脂紐で結合させるようにする。In the figure, 1 and 2 are conductors made of shape memory alloy.
Both are fixed to the tips of the support parts 3 and 4, and the tips 1a and 2a
The parts are molded so that they meet and come into contact with each other in normal conditions, and the contact parts are bonded with a low melting point alloy solder material, wood metal, resin, etc., or connected with a resin string.
前記導体１，２を構成する形状記憶合金は従来知られて

合金であって、ある形状に加工して後に５００〜１００
０℃程度の高温で熱処理することによって形状記憶させ
たもので、加熱すれば元の形状に戻る性質を有している
。As is conventionally known, the shape memory alloy constituting the conductors 1 and 2 is an alloy such as nickel-titanium, nickel-aluminum, copper-zinc, copper-zinc-aluminum, copper-tin 1, etc. 500~100 after processing into shape
It is shaped by being heat-treated at a high temperature of about 0°C, and has the property of returning to its original shape when heated.
したがって平常時、導体１と２間の通電は容易に行われ
るが、作用温度が形状記憶合金の変化点に達すると導体
１．２は記憶された元の形状に戻る。この記憶形状を導
体１，２両者の接触部が互に反撥する方向に曲るように
しておくこ−とによって、変形させて先端を接触させで
ある導体１，２は所定温度で反撥し合って接触を解放す
る。Therefore, under normal conditions, the conductor 1.2 is easily energized, but when the operating temperature reaches the change point of the shape memory alloy, the conductor 1.2 returns to its original memorized shape. By bending this memorized shape in such a way that the contact portions of both conductors 1 and 2 repel each other, the conductors 1 and 2 repel each other at a predetermined temperature by deforming and bringing their tips into contact. to release contact.
予め接触補強しである低融点合金とか樹脂は前記所定温
度で溶解するか軟化して導体１．２の開離を阻止しない
、もしくは温度と材料の種類を選択することによって応
答を確実にする。前記形状記憶合金の変化点は材質によ
り一数り０℃〜１１０℃程度のものが知られており、目
的に応じて任意に選択することができる。The low melting point alloy or resin used as the contact reinforcement may melt or soften at the predetermined temperature to prevent separation of the conductor 1.2, or the response may be ensured by selecting the temperature and material type. The change point of the shape memory alloy is known to be approximately 0°C to 110°C depending on the material, and can be arbitrarily selected depending on the purpose.
そして形状記憶合金でできた導体１，２は元の形状に戻
っても、再び形成させて先端を接触させれば同様に通電
ができ、通電中温度上昇すれば再び接触を解放して通電
遮断することができ、何度でも熱応答スイッチとして使
用することができる。Even if the conductors 1 and 2 made of shape memory alloy return to their original shapes, they can be re-formed and their tips can be brought into contact to conduct electricity in the same way, and if the temperature rises during the current flow, they will release the contact again and cut off the current flow. It can be used as a thermally responsive switch any number of times.
したがって従来のヒユーズのように１回限りでなく何回
も繰返して使用することができる効果がある。Therefore, it has the advantage of being able to be used many times, instead of just once like conventional fuses.
なお導体１，２の１部を形状記憶合金で形成し、或いは
導体の一方を固定にし側方を形状記憶合金で作ってもよ
い。また各導体先端の接触部には良導電性の接点合金を
取り付けたり被覆して使用することができる。Note that a portion of the conductors 1 and 2 may be made of a shape memory alloy, or one of the conductors may be fixed and the side portion may be made of a shape memory alloy. Further, the contact portion at the tip of each conductor can be attached or coated with a highly conductive contact alloy.
