Patent ID: 8808883

Claim:
A secondary battery pack comprising: a battery cell having an electrode assembly mounted in a battery case together with an electrolyte, the battery case having an open top sealed by a top cap; a protection circuit module having a protection circuit for controlling overcharge, overdischarge, and overcurrent of the battery cell; an insulative mounting member constructed in a structure in which the protection circuit module is loaded at a top of the insulative mounting member, the insulative mounting member being mounted to the top cap of the battery cell; and an insulative cap coupled to an upper end of the battery cell for covering the insulative mounting member in a state in which the protection circuit module is loaded at the insulative mounting member, wherein the top cap is provided with a pair of protruding electrode terminals having a first protruding electrode terminal and a second protruding electrode terminal, the top cap is provided at a partial region where the pair of protrusion electrodes are not formed with a recess that extends away from the protection circuit module to provide a depression space to allow elements loaded on a bottom of the protection circuit module to be received therein, the insulative mounting member is provided with first through-holes corresponding to the first and second protruding electrode terminals and a second through-hole corresponding to the depression space, the protection circuit module is provided with coupling through-holes corresponding to the first through-holes, and the coupling of the insulative mounting member and the protection circuit module to the battery cell is achieved by successively fixedly inserting the first and second protruding electrode terminals through the first through-holes of the insulative mounting member and the coupling through-holes of the protection circuit module.
