Abstract:
1. A method of making a protection circuit module for rechargeable batteries, the protection circuit module comprising: a substrate; electronic components mounted on an obverse surface of the substrate for forming a protection circuit for rechargeable batteries; a plurality of conductor plates mounted on the obverse surface of the substrate for external connection; a housing mounted on the obverse surface of the substrate and including a top wall partially defining an enclosure for accommodating the electronic components; and a resin sealer loaded in the enclosure of the housing for sealing the electronic components, wherein the top wall of the housing includes an opening for loading the resin sealer into the housing, and wherein the housing is rectangular and defines notched spaces at four corners of the housing beneath the top wall and outside the enclosure, the method comprising: forming a plurality of terminals on the top wall of the housing in a manner such that each of the terminals extends into a respective one of the notched spaces and is exposed at the respective one of the notched spaces; bonding the electronic components, the conductor plates and the housing onto the substrate simultaneously by heating in a manner such that the conductor plates project outward from the housing; and loading the resin sealer into the enclosure through the opening in the top wall of the housing.
