本発明は、蛍光管を用いた電子機器における、温度ヒユ

ユーズ実装方法は、第３図に示す如きであった。A conventional method of mounting a temperature fuse in an electronic device using a fluorescent tube is as shown in FIG.
第３図は、従来の温度ヒユーズ実装方法の斜視図であり
、第４図は、通常の温度ヒユーズの断面図である。FIG. 3 is a perspective view of a conventional thermal fuse mounting method, and FIG. 4 is a sectional view of a conventional thermal fuse.
第４図において、 温度ヒユーズは、通常、外ケース部

み、機器のｔｔａｔＡ、火災等を未然防止する。In FIG. 4, the temperature fuse is usually composed of an outer case part 7, a lead wire part 8, and an operating member 8. The operating principle is that normally the operating member 8 has four electrical connections, but
When the temperature fuse is heated above the rated temperature, the operating member 9 reacts thermally and becomes electrically non-conductive, and both ends of the lead wire 80 simultaneously become non-conductive. This produces results such as cutting off operating circuits, thereby preventing equipment damage, fires, and the like.
一方、第３図において、蛍光管１０は、基板１１へ実装

配線されている。On the other hand, in FIG. 3, the fluorescent tube 10 is mounted and fixed to the substrate 11. In addition, the outer case part 7 of the temperature fuse is
Although it is tightly fixed to the fluorescent tube 10 by the holding member 12, the lead wire portion 8 is wired without being in close contact with the fluorescent tube 10.

が温度ヒユーズの定格動作温度以上に発熱しても、温度
ヒユーズが、確実は動作しないという、重大な欠点を存
していた。However, in the conventional technology mentioned above, the outer case of a normal temperature fuse is made of a material with poor thermal conductivity, so even if the fluorescent tube generates abnormal heat, only the outer case remains tightly fixed to the fluorescent tube. In a decoy, the heat from the fluorescent tube is not transmitted to the operating parts inside the temperature fuse, and as a result, even if the surface of the fluorescent tube generates heat above the rated operating temperature of the temperature fuse, the temperature fuse will not operate reliably. It had a serious drawback.
そこで、本発明は、従来のこのような問題点を解決する
ため、簡単な実装構造にして、蛍光管の異常発熱を温度
ヒユーズで感知し、蛍光管面の温度が、温度ヒユーズの

を目的としている。Therefore, in order to solve these conventional problems, the present invention has a simple mounting structure, detects abnormal heat generation of the fluorescent tube with a temperature fuse, and detects the temperature of the fluorescent tube surface at the rated operating temperature of the temperature fuse. The purpose is to prevent damage to electronic equipment, fire, etc. by ensuring that the temperature fuse operates when the temperature reaches the temperature.

した、温度ヒユーズ実装方法。In order to solve the above problem, the temperature fuse mounting method of the present invention uses a fluorescent tube, and in order to prevent equipment damage, fire occurrence, etc. due to abnormal heat generation of the fluorescent tube, a temperature fuse mounting method of the present invention includes: A method for mounting a temperature fuse in an electronic device equipped with a temperature fuse, characterized in that a lead wire portion of the temperature fuse having good thermal conductivity is closely fixed to a fluorescent tube.
（作用〕
本発明の上記の構成によれば、蛍光管が異常発熱した際

した時点で確実に温度ヒユーズが動作する事により、電
子機器の損読、火災等を防止する事が可能である。(Function) According to the above configuration of the present invention, when the fluorescent tube generates abnormal heat, the temperature fuse is reliably activated when the temperature of the surface of the fluorescent tube reaches the rated operating temperature of the temperature fuse. It is possible to prevent misreading of equipment, fire, etc.
第１図、第２図は、本発明の一実施例を示す。 1 and 2 show an embodiment of the present invention.
第１図において、蛍光管３は、基板４へ実装固定される

光管の発熱部に、保持部材５によって密着固定される。In FIG. 1, a fluorescent tube 3 is mounted and fixed on a substrate 4. As shown in FIG. The outer case 1 and lead wire portion 2 of the temperature fuse are closely fixed to the heat generating portion of the fluorescent tube by a holding member 5.
この際、熱伝導性の良好なリード線部２は、図１の様に

光管から温度ヒユーズへの熱伝導効率を、一層高める事
ができる。At this time, the lead wire part 2, which has good thermal conductivity, is made to meander as shown in Figure 1 to increase the length of the lead wire part 2 that comes into close contact with the fluorescent tube surface.
By using a thermally conductive material for the holding member 5, the efficiency of heat conduction from the fluorescent tube to the temperature fuse can be further increased.
第２図においては、第１図の保持部材５の代わりに、接

る事は言うまでもない。In FIG. 2, instead of the holding member 5 in FIG. 1, an adhesive 6 is used to attach the temperature fuse outer case 1 to the fluorescent tube 3.
The lead wire portion 2 is glued. This allows the heat from the fluorescent tube to be transferred to the temperature fuse with even higher efficiency. It goes without saying that if a thermally conductive adhesive is used as the adhesive 6, the efficiency will further increase.
また、ｔＪ１図、第２図の様に、温度ヒユーズは蛍光管

い等の、工夫がされる。In addition, as shown in Figure tJ1 and Figure 2, the temperature fuse is placed below the fluorescent tube to save space and avoid increasing the width.

実装方法のため、蛍光管異常発熱時の管面温度と、温度

大きな実用的効果を持つ。As explained above, the present invention uses a mounting method in which the lead wire portion of the temperature fuse, which has good thermal conductivity, is closely fixed to the heat-generating portion of the fluorescent tube. This has an extremely large practical effect of ensuring that the operating temperatures of the fuses match.
