Abstract

The invention relates to a cap assembly for a secondary battery. The cap assembly of a secondary battery according to an embodiment of the present invention can comprise: a fixing part for fixing a top cap and a safety vent member on an upper part of a cap housing; and a protection part for protecting a current blocking member and an insulating gasket in a lower part of the cap housing. Therefore,the top cap and the safety vent member can be stably fixed to an upper part of a hollow part of the cap housing by the fixing part, and the current blocking member and the insulating gasket can be safely protected by the protection part in a lower part of the hollow part of the cap housing.

Description

technical field [0001] The present invention relates to a cover assembly for a secondary battery. More specifically, it relates to improving the assemblability of components when manufacturing the cover assembly, and easily managing some of the above components in a pre-assembled state to safely protect them from external shocks. The cover assembly of the secondary battery. Background technique [0002] In general, a secondary battery is a battery that generates electricity by causing an oxidation reaction and a reduction reaction of substances between an anode and a cathode by an electric current received from an external power source, and can be used semi-permanently by charging the generated electricity. The secondary battery as described above is composed of four core materials such as a separation membrane, an anode material, a cathode material, and an electrolyte. [0003] Generally, a primary battery (primary battery) such as a dry battery is configured to be used on...
