Abstract

The present invention relates to a cap assembly for a secondary battery. In the cover assembly of the secondary battery of the embodiment of the present invention, a fixing part for fixing the top cover and the safety through hole part is formed on the upper part of the cover cover, and a protection part for protecting the current disconnection part and the insulating gasket is formed at the lower part of the cover cover. department. Therefore, the above-mentioned top cover and the above-mentioned safety through-hole part are stably fixed on the upper part of the hollow part of the above-mentioned cover housing through the above-mentioned fixing part, and the above-mentioned current breaking part and the above-mentioned insulating gasket pass through the above-mentioned protection part and are fixed in the hollow part of the above-mentioned cover housing. The lower part is securely protected.

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...
