BACKGROUND ART A temperature sensor such as a thermistor, bonostar, thermoswitch, etc. is attached to a storage battery to monitor the temperature of the storage battery. The temperature sensor was attached to the storage battery in the following manner. In other words, when a thermoswitch is used as a temperature sensor, the thermoswitch itself is usually covered with an insulating coating, so as shown in FIG.
The thermoswitch 2a was attached directly to the storage battery 1 by wrapping adhesive tape 5 around it, but since the thermoswitch 2a is larger than the other elements as temperature sensors, the storage space is also larger, and its heat capacity is higher than that of other elements. Because it is larger than the element, it is not suitable for accurately capturing rapid temperature changes. When the element 2b such as a diode, thermistor, or vegetator is used as a temperature sensor, these elements are usually connected with bare lead wires, and the element 2b itself is not insulated, so the temperature sensor shown in FIG. As shown in FIG. 2, an insulating cover 6 is placed over the storage battery 1, and the element 2b is attached thereon using an adhesive tape 5 or the like. However, since these elements 2b have a small volume and a small heat capacity, they should be able to follow thermal changes well, but in reality, the existence of the insulating cover 6 makes it difficult to detect temperature. Accuracy has deteriorated. Furthermore, by using the element 2b provided with an insulating coating,
Even if it is attached directly to the outer surface of the storage battery 1, if the adhesive tape 5 is used, the contact area between the element 2b and the storage battery 1 is small and heat conduction is poor, making it difficult to monitor the temperature with high accuracy. Since there is no certainty in the installation of
This may cause the element 2b to fall off.

In addition to ensuring reliable fixation by adhesive fixing, heat conduction between the storage battery and the temperature sensor is achieved by using a thermally conductive adhesive as the adhesive. The present invention will be described in detail below based on the illustrated embodiments.
The figure shows one example, and the diode, thermistor,
When attaching the temperature sensor 2 made of a POSISTOR or the like to the storage battery 1, the temperature sensor 2 is bonded to the outer surface of the storage battery 1 using an adhesive 3 that has insulating properties and high thermal conductivity, and the temperature sensor 2 is attached using the adhesive 3. I try to cover it. Since the temperature sensor 2 is suspended from the storage battery 1 with the adhesive 3, even if the temperature sensor 2 does not have an insulating coating, the storage battery 1
The temperature sensor 2 can be insulated from the temperature sensor 2 by using the adhesive 3. In other words, the adhesive 3 here not only attaches the temperature sensor 2, but also insulates it and improves the thermal conductivity between the storage battery 1 and the temperature sensor 2. Of course, when the temperature sensor 2 is coated with an insulating coating, it is more preferable to fix the storage battery 1 and the temperature sensor 2 with the adhesive 3 so that they are in direct contact with each other. Figure @2 shows another embodiment, in which a water absorbing member 4 covering the storage battery 1 for absorbing liquid leakage and having insulating properties is covered with heat conductive and insulating material as in the above embodiment. The temperature sensor 2 is attached with an adhesive 3 that is permeable and has permeability. The adhesive 3 is a water absorbing member 4 for absorbing liquid leakage.
Since the water permeates into the outer surface of the storage battery 1 and contacts the outer surface of the storage battery 1, sufficient thermal conductivity between the storage battery 1 and the temperature sensor 2 is ensured even though the water absorbing member 4 is interposed. Figure 3 shows yet another embodiment, which differs from the above embodiment in that a large number of small holes 40 are provided on the mounting surface of the temperature sensor 2 in the water absorbing member 4. Even without using a permeable adhesive 3, the adhesive 3 ensures thermal conductivity between the storage battery 1 and the temperature sensor 2 through the small holes 40. In place of the small hole 40 in the above embodiment, a mounting hole 41 into which the temperature sensor 2 can be fitted, as shown in FIG.
may be provided on the water absorbing member 4. In this case, storage battery 1
Since the distance between the water absorbing member 4 and the temperature sensor 2 becomes short despite the presence of the water absorbing member 4, even better thermal conductivity can be ensured. In addition, the insulation of the lead wire 21 is provided by the water absorbing member 4.
It can be secured at In addition to the embodiment shown in FIG. WrJ4, FIG. 5 shows a case where the temperature sensor 2 is more securely fixed by wrapping an adhesive tape 5 around it. If a heat-shrinkable adhesive tape 5 is used, even when the storage battery 1 becomes high temperature, the adhesive tape 5 will not stretch but will contract, so that the temperature sensor 2 and the storage battery 1 can be The contact between them becomes more reliable and the thermal conductivity becomes better.

ある。As described above, in the present invention, since the temperature sensor is attached to the storage battery using a thermally conductive adhesive, not only the temperature sensor can be attached reliably, but also the thermal conductivity between the temperature sensor and the storage battery can be improved. It can be maintained in good condition and the temperature of the storage battery can be properly monitored.
