Abstract
本発明の課題は、電極に極性があり電気化学セルを逆方向に回路に実装すると電気化学セル内部で腐食を生じることと、電気化学セルと回路基板のハンダ付け強度が弱いことである。
【解決手段】
本発明の電気化学セルは、底面の同一対角線上の角部に形成された一対の正極端子と、前記正極端子と異なる対角線上の角部に形成された一対の負極端子とからなる。本発明を用いると、正極接続端子と負極接続端子が対称位置に配されているため電気化学セルが180度反対に回路基板に実装されても極性が一定となる。このため溶接部が常に負極側となり、電気化学セル内部で腐食が生じることがない。
【選択図】 図1
Description
第一の正極端子2a、第二の正極端子2b、第一の負極端子3a、第二の負極端子3bが、それぞれ電気化学セルの角部に設けられている。第一の正極端子2aと第二の正極端子2bは、電気化学セルの底面の同一対角線上に形成されている。第一の負極端子3aと第二の負極端子3bは、正極端子とは異なる対角線上に形成されている。電気化学セルが180度反対に回路基板に実装されても端子の極性が反対に接続されないようになっている。
