二次電池とその充電装置

Secondary battery and charger

Abstract

PROBLEM TO BE SOLVED: To provide a battery and a charger to enable primary battery and a secondary battery to be distinguished so as not to set a primary battery by mistake. SOLUTION: The diameter of a positive electrode terminal 1a of the R6-type cylindrical secondary battery 10 is designed to be not less than 1.0mm and less than 4.2mm, a smaller diameter than that of the Japanese Industrial Standard. Other dimensions are same as those of the R6-type battery. A charger 20 for charging the cylindrical secondary battery 20 is different in structure to the charging terminal of the positive electrode side from on those currently in use. The structure of the charging terminals, composed of the positive electrodes 2a, on the outside of them the elastic parts and the further outside of them reinforcing parts 4. The reinforcing parts 4 restrict to not to widen the interval of two positive electrode terminal so as not to exceed the specified interval. The elastic parts 3 activate to press the positive electrodes 2a against a positive electrode terminal 1a to ensure electric connectivity. COPYRIGHT: (C)1998,JPO
(57)【要約】 【課題】 一次電池と二次電池とがはっきりと区別さ れ、一次電池が誤って充電装置に装着されないことを目 的とする。 【解決手段】 単3形の円筒形二次電池10は、正極端 子1aの外径が1.0mm以上、4.2mm未満に設定 されていて、日本工業規格の外径より小さく設定する。 その他の寸法は単3形と同一とする。円筒形二次電池1 0を充電する充電装置20は、従来とは正極側の充電用 端子の構造において異なる。充電用端子の構造は円筒形 二次電池10の正極端子1aを挟むように充電装置20 の正極側端子2aと、その外側に弾性部材3と、更にそ の外側に補強部材4とが設けられている。補強部材4は 2つの正極側端子2aが所定以上に開口しないように制 限する。また、弾性部材3は正極側端子2aを正極端子 1aに押し当て、電気的接続性を確保する。
