を利用し、使用機器において短絡等の大電流による電池
の加熱又は破損を防止するものである。This type of battery has the PTC characteristics of a PTC element (a characteristic that shows low resistance at room temperature and increases with temperature.)
To prevent the battery from being heated or damaged by a large current such as a short circuit in the equipment used.
発明が解決しようとする課題 しかし、このような従来の構成では、PTC素子と電池

流が流れてPTC素子が動作した場合、PTC素子が発熱し、
その熱により樹脂ケースが変形するという問題点を有し
ていた。However, in such a conventional configuration, since the PTC element and the case for storing the battery are close to each other, the PTC element operates when a large current such as a short circuit flows and the PTC element operates. Fever,
There was a problem that the resin case was deformed by the heat.
課題を解決するための手段 本発明は、上記の問題点を解決するために、樹脂ケー

構成としたものである。Means for Solving the Problems In order to solve the above problems, the present invention provides a protrusion for fixing a battery terminal surface on a side where a PTC element is arranged as a shape of a battery housing portion of a resin case, and the battery is made of resin. The projection and the battery terminal surface surround in the state where it is arranged in the case,
In addition, the structure has a heat-dissipating space in which the PTC element faces.
作用 この手段による作用は次のようになる。Operation The operation of this means is as follows.
即ち、PTC素子が動作し、PTC素子が発熱してその温度

ースと離れて取り付えられているため、PTC素子の熱が
樹脂ケースに直接的に伝わらず、樹脂ケースの熱による
変形を防ぐことができる。That is, even if the PTC element operates and the PTC element generates heat and its temperature reaches the deformation temperature of the resin case, the heat of the PTC element is removed because the PTC element is mounted separately from the resin case. And the deformation of the resin case due to heat can be prevented.

ス４には、なんらの熱による変形もなかった。Next, the configuration of the battery will be described. Lithium batteries are used as the unit cells 1 and 2, a conductive polymer is used as the PTC element 3, and an ABS resin is used as a material of the resin case 4 to form a resin pack type battery. At the bottom of the resin case 4, a battery position regulating projection 6 was formed so that the PTC element 3 and the bottom of the resin case 4 were sufficiently separated from each other. Then, the resin pack type battery was forcibly short-circuited for 1 minute. At this time, the temperature of the PTC element 3 had reached 90 ° C., but the resin case 4 was not deformed by any heat.
以上のように、PTC素子が電池を収納する樹脂ケース

の発熱による樹脂ケースの変形を防ぐことができる。As described above, since the PTC element is mounted separately from the resin case that houses the battery, it is possible to prevent the resin case from being deformed due to heat generated during operation of the PTC element.
なお、本実施例では樹脂ケースの形状を第１図に示す
ものにしたが、形状はこれに限定されるものではなく、
PTC素子と離れるような形状であれば、同様な効果が得
