れることが要求されてきた。Conventional technology In order to protect the equipment, power supplies for portable consumer devices such as VTRs require (1) ensuring safety in the event that the positive and negative terminals are accidentally shorted, and (2) rapid charging using large currents. Therefore, in order to prevent the battery from being overcharged in the event of a charger malfunction and the resulting heat generation causing deformation of the battery case, it has become necessary to incorporate a self-resetting thermostat as a protective device. .

ていた。 Conventionally, in this type of sealed storage battery, a group of electrode plates consisting of a positive electrode plate, a negative electrode plate, and a separator was housed in a container made of ABS resin or polypropylene, and a thermostat was housed on one side of the container wall. .

を阻止できなかつた。Problems to be Solved by the Invention However, in such conventional storage batteries, the thermostat is
The drawback was that only the heat generated by the cell was transmitted. Therefore, even if a cell that is not in close contact with the thermostat generates heat due to a short circuit between the positive electrode plate and the load plate, the heat generated by the cell is not sufficiently transmitted to the thermostat, making it impossible to prevent the battery from generating heat.
本発明は上記従来の欠点を解決するもので、電
池内の温度上昇時の検出が確実で安全性に優れた
密閉形蓄電池を提供することを目的とする。 The present invention solves the above-mentioned conventional drawbacks, and aims to provide a sealed storage battery that can reliably detect a rise in temperature within the battery and has excellent safety.

ものである。Means for Solving the Problems The present invention provides aspects of a unit battery consisting of a plurality of cells,
In other words, a lead plate is placed across each side of a plurality of cells so that it is in close contact with these cells, and one end of the lead plate is integrated with one terminal provided in the case, and the other end of this lead plate is connected to one terminal of the thermostat. The thermostat is housed in a case with the thermostat tightly attached to the side of one of the cells.

して電池を発熱発火より保護することができる。Effect With this configuration, if an abnormality occurs in a cell that the thermostat is in close contact with and the temperature rises, the thermostat will directly detect the temperature rise in the cell, and the cell that the thermostat is not in direct contact with will also detect the temperature rise due to an abnormality. If the temperature rises, the temperature rise is detected via the lead plate and the metal container of the thermostat. As a result, the thermostat opens and stops energizing, thereby protecting the battery from heat generation and ignition.
