Patent ID: 7763379

Claim:
A cap assembly mold mounted to a battery cell, in which an electrode assembly including cathodes/separators/anodes is disposed, wherein the cap assembly mold is manufactured by integrally forming a protection circuit board, a safety element, two connection terminals, and a cap housing by insert injection molding, when the insert injection molding is carried out, the connection terminals are partially exposed from a lower end surface of the cap assembly mold such that the connection terminals can be electrically connected to electrode terminals of the battery cell, and wherein the protection circuit board is provided with two through-holes, and the cap housing, which is integrally formed with the protection circuit board, is also provided with two through-holes, which correspond to the through-holes of the protection circuit board, such that a protruding middle portion of each connection terminal communicates with the through-holes from an upper part of the cap assembly mold while the connection terminals are attached to the protection circuit board, and wherein the connection terminals have a same shape, the protruding middle portion of each connection terminal protrudes toward a battery cell, the protruding middle portion of each connection terminal is coupled to a corresponding electrode terminal of the battery cell, an end of each connection terminal, which is opposite to the protruding middle portion of each connection terminal, is connected to the protection circuit board, and a length of the protruding middle portion of a first connection terminal, which is coupled to a protruding anode terminal of the battery cell, is less than a length of a protruding middle part of a second connection terminal, which is coupled to a cathode terminal of the battery cell.
