摘要： A cap (8) for covering an open side of a battery case (15) containing a power generation element (51) includes a protective circuit with an electric circuit (11) formed on a circuit board (10). The circuit board (10) is mounted outside the cap (8). A positive terminal block (16) acting as positive terminals of rechargeable battery (A) and an S-pole terminal block (14) for controlling the operation of the electric circuit (11) by an external connection are provided on the outside of the circuit board (10). Since the protective circuit is provided in the cap so as to protect the battery from excessive discharge or charge, there is no need for provision of a packed cell.

摘要： An opening sealing device for enclosed batteries, having an explosion-proof mechanism, wherein a metal plate (8) having a through hole (81), an insulating resin sheet (9), a thin metal plate (6b), an insulating sheet (4) having a through air hole (41), a metal guide plate (3) having a through hole (31), and a metal cap (1b) are laminated in order on an inner side of an insulating gasket (5b), the metal plate (8) and metal guide plate (3) contacting each other to provide electrical conduction, the insulating resin sheet (9) being expanded and broken when the inner pressure of a battery increases, to cause a narrow portion (69) of the thin metal plate (6b) provided on the sheet (9) to be broken and cut off an electric current.

摘要： A sealed battery wherein a metallic reinforcing plate (3) is welded fixedly to that portion of the internal surface of a battery case (1) near an opening part, and an insulating resin gasket (2) and a sealing member (5) incorporating an explosion-proof mechanism for a battery are put on the metallic reinforcing plate (3) sequentially, whereby eliminating the conventional need for forming a recessed part by caulking in the upper part of the side surface of the battery case (1) to provide the sealed configuration of the battery capable of eliminating wasteful space for increasing the capacity of the battery and securing the reliability for an explosion-proof mechanism and leakage prevention measure.
摘要翻译： 金属加强板（3）焊接在电池壳体（1）的内侧的开口部的适当位置，塑料绝缘垫圈（2）和具有防爆机构的密封部件（5） 依次安装在金属加强板（3）上。 通过这种布置，通过消除空间的浪费可以实现更高的电池容量，因为不需要以常规方式在电池壳体（1）的上壁周围形成常规的凹陷。 因此，可以获得具有防爆机构并且在防漏性方面是高可靠性的密封电池结构。
