  • Patent number: 7976969
    Abstract: Disclosed herein is a no-welding type battery pack using one or more forced-inserting type rivets. A cap assembly includes a base plate mounted to an open upper end of a battery case, a protection circuit module (PCM) mounted on the base plate, and a top cap coupled to the upper end of the battery case while the top cap covers the PCM. The top cap is made of an insulative material. The electrical connection and the mechanical coupling between the PCM and the base plate are accomplished by one or more forced-inserting type rivets. The cap assembly is included the battery pack. The no-welding type battery pack using the one or more forced-inserting type rivets is manufactured without welding or soldering requiring an excessive amount of time and skilled technique during the electrical connection between the battery cell and the PCM. As a result, the assembly process of the battery pack is simplified, and therefore, the manufacturing time of the battery pack is reduced.
