Abstract
Disclosed is a pack type secondary battery that can be assembled by a simple process. The secondary battery comprises: a bare cell; a protection circuit module including a circuit board and a supporting member to combine the circuit board with the bare cell; and a top case covering the circuit board of the protection circuit module, where the supporting member of the protection circuit module is provided with a first coupling part and the top case is provided with a second coupling part combined with the first coupling part and the first coupling part of the supporting member is combined with the second coupling part of the top case by an interference fit method.
Claims20
A secondary battery, comprising:
- a bare cell;
- a protection circuit module including a circuit board and a supporting member to combine the circuit board with the bare cell;
- and
- a top case covering the circuit board of the protection circuit module,
- where the supporting member of the protection circuit module is provided with a first coupling part and the top case is provided with a second coupling part combined with the first coupling part.
A secondary battery comprising:
- a bare cell having a first surface;
- a protection circuit module;
- at least one supporting member that interconnects the protection circuit module to the bare cell so as to mount the protection circuit module adjacent the first surface of the bare cell;
- a top case that is positioned in a mounting orientation over the first surface of the bare cell and the protection circuit module so that the protection circuit module is interposed between the top case and the first surface, wherein the top case and the at least one supporting member mechanically engage with each other so as to retain the top case in the mounting orientation.
