Abstract:
1. 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 on the insulative mounting member, wherein the top cap is provided with a pair of protrusion electrode terminals including a first protrusion electrode terminal connected to a cathode of the electrode assembly and a second protrusion electrode terminal connected to an anode of the electrode assembly, the insulative mounting member is provided with through-holes corresponding to the protrusion electrode terminals, the protection circuit module is provided with through-holes corresponding to the protrusion electrode terminals, and the coupling of the insulative mounting member and the protection circuit module to the battery cell is achieved by successively fixedly inserting the protrusion electrode terminals through the through-holes of the insulative mounting member and through the through-holes of the protection circuit module.
