Connecting structure for electrode protective cover of dry battery

The utility model provides a dry battery electrode protective cover connecting structure, which comprises a groove formed by the inward concave of the outer peripheral wall of a dry battery positive terminal and a bulge formed by the inward convex of the inner peripheral wall of a dry battery electrode protective cover, and the dry battery electrode protective cover coaxially covers the dry battery positive terminal. And the bulge is clamped into the groove, so that the bulge cannot move in the axial direction of the dry battery. According to the utility model, the connection firmness between the positive terminal and the electrode protection cover is slightly influenced by the inner diameter difference of the dry battery electrode protection cover, and the electrode protection cover is easy to install and not easy to fall off. 本实用新型提供一种干电池电极保护盖连接结构，包括干电池正极端子的外周壁向内凹形成的凹槽和干电池电极保护盖的内周壁向内凸形成的凸起，所述干电池电极保护盖同轴盖设在干电池正极端子上，所述凸起卡入所述凹槽内使其不能在干电池的轴向上进行移动。本实用新型的所述正极端子与电极保护盖之间的连接牢固性受干电池电极保护盖内径差异化影响小，电极保护盖易安装且不易脱落。
