Description
【発明の詳細な説明】 この発明は、温度ヒユーズの改良に関するものである。[Detailed description of the invention] This invention relates to improvements in temperature fuses.
従来、温度ヒユーズは各a形式のものが提案され、実用
化されている。例えば第1図に示すように、相対向する
リード線1間に可溶合金2を接続し、そして絶縁容器3
を被せ、その両端全密封材4で封止したものにおいて、
このような温度ヒニーズでは、溶断後、可溶体を偏在さ
せるところが、リード線の両端の接続部しがないのでそ
の両端へ偏在させる力が弱く、そのためリード線間の中
央部に可溶体が残ることが多く、従ってその絶縁性の信
頼性に欠けるところとな9時には短絡してしまう危険性
さえある。Conventionally, various type A temperature fuses have been proposed and put into practical use. For example, as shown in FIG. 1, a fusible alloy 2 is connected between opposing lead wires 1, and an insulating container 3
in which both ends are completely sealed with sealing material 4,
In such temperature hinnies, after fusing, the soluble material is unevenly distributed because there is no connection at both ends of the lead wire, so the force to distribute the soluble material unevenly to both ends is weak, so the soluble material often remains in the center between the lead wires. Therefore, there is a risk that the insulation may be unreliable and a short circuit may occur.
また溶断速度も遅い等の欠点があった。It also had drawbacks such as slow fusing speed.
この発明は上記の欠点を解消させることのできる温度ヒ
ユーズを提供すること金目的とするものである。The object of the present invention is to provide a temperature fuse which can overcome the above-mentioned drawbacks.
この発明によれば、温度ヒユーズの溶断時に可溶体が金
属部材に偏在するので、可溶体を確実に溶断するととも
°に、リード線間の中央部に可溶体を残すことがないの
で、溶断後の絶縁性が高い。この金属部材は可溶体に対
しぬれ性のよい金属で接続部の周辺部またはその一部に
設けてもよいし、リード線の先端ヲロ状にしてもよい。According to this invention, since the fusible material is unevenly distributed in the metal member when the temperature fuse is blown, the fusible material is reliably blown out, and since no fusible material is left in the center between the lead wires, the fusible material is not left in the center between the lead wires. High insulation properties. This metal member may be a metal having good wettability with respect to the fusible material and may be provided around or a part of the connection portion, or may be formed into a hollow shape at the tip of the lead wire.
またこの発明によれば、温度ヒユーズの溶断時、可溶体
に対する絶縁容器内面と金属片とのぬれ性の差によル、
その溶断速度が早くなる。Further, according to the present invention, when the temperature fuse is blown, due to the difference in wettability between the inner surface of the insulating container and the metal piece with respect to the fusible material,
The fusing speed becomes faster.
またこの発明によれば、可溶体の内部に7ラツクスが充
填されているので、可溶体の温度上昇に伴い、フラック
スの温度が上昇してフラックスの溶剤が気化する。この
ため可溶体内部の圧力が上昇して、可溶体の溶断速度を
早めるとともに溶断を確実ならしめる。Further, according to the present invention, since the interior of the fusible body is filled with 7 lux, as the temperature of the fusible body rises, the temperature of the flux rises and the solvent of the flux evaporates. For this reason, the pressure inside the fusible body increases, which speeds up the fusing speed of the fusible body and ensures reliable fusing.
以下、この発明を、金属部材を接続部周辺部に設けた場
合の実施例を図面に基づいて説明する。Hereinafter, an embodiment of the present invention in which a metal member is provided around a connecting portion will be described based on the drawings.
第2図において、11はリード線、12は可溶体で、例

位置に、第3図に示すように、容器13の内周面に沿っ
て設置されている。In FIG. 2, 11 is a lead wire, 12 is a fusible material, such as an alloy made of tin, lead, cadmium, etc. 013 is a ceramic container, 14 is a heat-resistant sealant for sealing the container 13, and 15 is a A metal tube made of copper, copper alloy, etc., which has good wettability with the fusible body, or having a composition similar to that of the lead wire, is placed around the connection between the lead 1j311 and the fusible body 12, as shown in FIG. , are installed along the inner peripheral surface of the container 13.

せる力が働きこれによって第4図に示すように可溶体1
2が速やかに確実に溶断され、可溶体12がリード線間
の中央部に残ることもない。When the temperature of the fusible body 12 of the temperature fuse composed of the above rises, the fusible body 12 softens and melts, contacts the container 13 and the metal pipework 5, and due to the difference in wettability between the container 13 and the metal pipe 15, A force acts to unevenly distribute the melted fusible alloy 12 in the metal pipe work 5, and as a result, as shown in FIG.
2 is quickly and reliably fused, and the fusible body 12 does not remain in the center between the lead wires.

The melting temperatures of these temperature fuses were measured by flowing an IA current.

ておいた場合もほぼ同様の結果が得られた。(Leaving space below) As can be seen from Table I, the operating temperature of the temperature fuse in the example (a) has small variations in (b) and f (b), assuming the entire center of 146.6 IC.The temperature fuse in (a) has stable performance. It turns out that it has. Also, after the above experiment, 100OV
When I checked the insulation resistance at the time of application, ←) was 1012 Ω or more, and (b) was 1 () 10 Ω on average, and (
It was found that the thermal fuse (a) also has high reliability in terms of insulation after operation. This example shows a case in which a metal member is provided around the connection part, but it may also be possible to place a metal member around a part of the periphery instead of the entire circumference, or if the tip of the lead wire is made of the same material and formed into a shape. Almost similar results were obtained.

省略する。FIG. 5 shows another embodiment in which a soluble body 12 is filled with 7 lux 16, and this 7 lux contains, for example, gum rosin, amine hydrochloride as an activator, and isopropyl 7 as an organic solvent. /l/coal, etc., not only prevents the oxidation of the soluble material, but also has the function of accelerating the speed of fusing due to the pressure of the vapor of the organic solvent, as well as the 7 lux effect at the time of fusing. Furthermore, the second
Components that are the same as those in the figures are given the same reference numerals, and therefore their explanations will be omitted.

Therefore, the soluble body 12
When the internal pressure rises and the temperature further rises to reach the melting temperature, the softened fusible body 12 is destroyed and the flux 16 escapes, and at the same time, the fusible body 12 is melted as shown in FIG. let

縁性が高く、さらに溶断速度が早くなる。As described above, in this invention, a metal piece with good wettability to the fusible body is installed around the connection part between the fusible body and the lead wire, so that the melted fusible body is unevenly distributed on the metal piece. Therefore, the fusible material is reliably blown out, and no fusible material is left in the center between the lead wires, resulting in high insulation properties after fusing, and a faster fusing speed.
