【考案の詳細な説明】
本考案は温度の異常な上昇を検知して断線しう
る異常温度検知線に関するものである。[Detailed Description of the Invention] The present invention relates to an abnormal temperature detection line that can detect an abnormal rise in temperature and be disconnected.

タル式温度検知装置や温度ヒユーズ等各種のもの
が用いられている。 BACKGROUND ART Conventionally, various devices such as bimetallic temperature detection devices and temperature fuses have been used to detect abnormal temperature increases indoors or in equipment to prevent accidents or destruction.
ところで、最近、温度ヒユーズ的機能を有する

断するものである。 Incidentally, recently, an abnormal temperature detection line having a temperature fuse-like function has been devised. This abnormal temperature detection wire is constructed by covering a conductor made of a low-melting point metal with a flame-retardant plastic insulator that turns into a sticky molten substance in the conductor's melting point region. When the temperature of the conductor rises abnormally, the conductor breaks, and the broken part is filled with molten flame-retardant plastic insulator to cut off the flowing current.

ために、導体と回路等とを絶縁し難く再び導通し
機器等が破壊される欠点があつた。 Unlike a conventional temperature fuse or the like, such an abnormal temperature detection line has the advantage that the entire conductor part serves as an abnormal temperature detection part, and it can reliably detect abnormal temperatures in the surroundings. However, when connecting this detection wire to a circuit, etc., the insulation at both ends of the detection wire is usually removed, which makes it more likely that abnormal temperatures will be detected at both ends than at other parts covered with insulation. The conductor may melt at the exposed portions at both ends. When a conductor is fused at both ends connected to a circuit or the like, since the insulator has been removed, it is difficult to insulate the conductor from the circuit, causing the conductor to become electrically conductive again and destroying the equipment.
本考案は、以上の欠点を改良し、温度の異常上
昇を確実に検知し誤動作を防止し機器等の破壊を
未然に防止しうる異常温度検知線の提供を目的と
するものである。 The present invention aims to overcome the above-mentioned drawbacks and provide an abnormal temperature detection wire that can reliably detect abnormal increases in temperature, prevent malfunctions, and prevent damage to equipment, etc.

常温度検知線を提供するものである。 In order to achieve the above object, the present invention includes a conductor made of a low-melting point metal, a flame-retardant plastic insulator coated on the circumference of the conductor and capable of melting near the melting point of the conductor, and a flame-retardant plastic insulator coated on the circumference of the conductor and capable of melting near the melting point of the conductor. The present invention provides an abnormal temperature detection line consisting of a notch that is provided in the middle of an object and reaches the conductor.
以下、本考案の実施例を図面に基づいて説明す

設けられている。 In the figure, 1 is a conductor, such as bismuth, lead,
Consists of low melting point metals such as tin, cadmium, and indium, either alone or as an alloy. 2 is a flame-retardant plastic insulator covering this conductor 1;
It is made by adding decaprom dephenyl ether, antimony trioxide, etc. to an ethylene-vinyl acetate copolymer, and its melting point is set approximately to the melting point of Conductor 1. In particular, a cut is provided halfway through the flame-retardant plastic insulator 2 to reach the conductor 1.

温度検知線５は確実に電気的に開放される。 Since the present invention is constructed as described above, even if the flame-retardant plastic insulation 2 near both ends of the conductor 1 is removed and the ends of the conductor 1 are exposed, such temperature fuses will normally be removed. When arranging the abnormal temperature detection wire 5 having the function of
Since a notch 3 reaching the conductor 1 is formed in the middle, the conductor 1 at the part of the notch 3 is more likely to be fused. The conductor 1 at this notch 3 is
When an abnormal rise in temperature is detected, the conductor 1 melts, and the flame-retardant plastic insulator 2 having approximately the same melting point also melts, and the melted insulator 2 fills the fusing portion 4 as shown in FIG. This ensures that the abnormal temperature detection line 5 is electrically opened.
