電槽の開放端を気密に密閉するグロメットに配置した透孔を挿通する接続端子に設けられた第１端子と、蓄電池内部に固定された第２端子とを備え、
前記グロメットの撓み変形に伴う前記第１の端子の移動によって前記第１の端子と前記第２端子とが当接・離脱することによって、前記スイッチが前記電極と前記外部端子を結ぶ回路のオン・オフの切り替えを行うとともに、前記安全弁が、前記グロメットに破断を生ぜしめることによって、ガスを排出することを特徴とする密閉形蓄電池。 A switch that turns off the circuit that connects the electrode and external terminal when the gas pressure inside the sealed battery rises, and a safety valve that releases the gas accumulated inside the battery when the pressure inside the battery rises abnormally A sealed storage battery comprising:
A first terminal provided in a connection terminal that is inserted through a through-hole disposed in a grommet that hermetically seals the open end of the battery case; and a second terminal that is fixed inside the storage battery,
The first terminal and the second terminal are brought into contact with and separated from each other by the movement of the first terminal accompanying the bending deformation of the grommet, so that the switch connects the electrode and the external terminal. A sealed storage battery characterized by switching off and discharging the gas by causing the safety valve to break the grommet.
１（ｍｍ）≦ａ−ｂ≦３（ｍｍ）
の関係が成り立つことを特徴とする請求項１記載の密閉形電池。 A circular through hole that is provided with a circular inner flange portion on the connection terminal, includes a sealing plate that is outside the grommet and is fixed to the open end of the battery case, and that is concentric with the inner flange portion on the sealing plate. When the diameter of the through hole is a millimeter (mm) and the diameter of the inner flange portion is b (mm),
1 (mm) ≦ ab−3 (mm)
The sealed battery according to claim 1, wherein:
ａ≦ｃであって、かつ、ｄ≦ｂ＜ａ
の関係が成り立つことを特徴とする請求項１または２記載の密閉形電池。 A circular through hole that is provided with a circular inner flange portion on the connection terminal, includes a sealing plate that is outside the grommet and is fixed to the open end of the battery case, and that is concentric with the inner flange portion on the sealing plate. A ring-shaped groove having an outer periphery and an inner periphery that are concentric with the inner flange portion, the diameter of the through hole being a millimeter (mm), and the diameter of the inner flange portion being b (mm) When the outer diameter of the groove is c (mm) and the inner diameter is d (mm),
a ≦ c and d ≦ b <a
The sealed battery according to claim 1, wherein the following relationship is established.
