に接している計器２のケーシング２ａが上記熱により約
１６０℃〜２００℃で溶融して発火する虞れがあった。However, in such a structure, the neck portion 1
c becomes red hot at 780℃~1 when an overcurrent flows through the meter.
It melts at 080°C, but the neck part 1c
There was a risk that the casing 2a of the instrument 2 in contact with the above-mentioned heat would melt at approximately 160°C to 200°C and cause a fire.
そこでこの難点を解消するだめに、計器ケーシング２ａ
を例えばフッ素系樹脂、フェノール樹脂などの難燃材と
することが考えられるが、著しくコストアップとなる欠
点があった。Therefore, in order to solve this difficulty, the instrument casing 2a
It is conceivable to use a flame retardant material such as a fluororesin or phenol resin for example, but this has the drawback of significantly increasing costs.
本発明は上記点に鑑みなされたもので、計器ケーシング

ケーシングの発火を未然に防止するようにした自動車計
器の発火防止構造を提供するものである。The present invention has been made in view of the above points, and includes providing a space in a portion corresponding to the neck of the instrument casing, or by embedding a flame retardant material in the space so that the neck directly connects to the casing. To provide an ignition prevention structure for an automobile meter that inexpensively prevents ignition of a casing by preventing contact with the casing.
以下第４図以降を参照して本発明の詳細な説明する。The present invention will be described in detail below with reference to FIG. 4 and subsequent figures.
本発明は第４図ａ、ｂに示すように、前記計器２のケー
シング２ａにおける前記フレキシブルプリンデッド回路
部材１における一般回路１ｂのネック部１ｃに対応する
部分に貫通穴３を開設し、該ネック部１ｃが直接ケーシ
ング２ａに接しないようにする。As shown in FIGS. 4a and 4b, in the present invention, a through hole 3 is formed in a portion of the casing 2a of the meter 2 corresponding to the neck portion 1c of the general circuit 1b in the flexible printed circuit member 1, and Prevent the portion 1c from coming into direct contact with the casing 2a.
第５図ａ、ｂは前記貫通穴３０代りに、ネック部１ｃに
対応する部分に凹部４を形成した本発明の第２の実施例
である。FIGS. 5a and 5b show a second embodiment of the present invention in which a recess 4 is formed in a portion corresponding to the neck portion 1c instead of the through hole 30.

発明の第３の実施例である。FIG. 6 shows a third embodiment of the present invention in which a flame retardant material 5 such as fluororesin or phenol resin is embedded in the recess 4 in the second embodiment.
以上のように本発明自動車計器の発火防止構造によれば

で安価に提供できるものである。As described above, according to the ignition prevention structure of the automobile instrument of the present invention, a space portion such as a through hole or a recess is provided in the portion of the instrument casing corresponding to the neck portion of the flexible printed circuit member, or a space portion is not designed. Since flame retardant material is buried in the space to prevent the neck from directly contacting the instrument casing, there is no risk of the casing catching fire even if an overcurrent flows through the instrument and the neck becomes red hot. It has a structure that can be provided at low cost.
又、ケーシングの凹部に難燃材を埋設したものは、発火
防止効果が倍加するものであり、この場合埋設面積は狭
いのでそれ程コストアップとはならない。Furthermore, if the flame retardant material is buried in the recessed portion of the casing, the fire prevention effect is doubled, but in this case, the buried area is small, so the cost does not increase much.
