Abstract
An external terminal assembly for establishing a connection between a battery pack and an electrical connector of an external device and a battery pack including the same, the external terminal assembly including an external terminal, the external terminal being electrically connectable to the electrical connector of the external device; a terminal holder on a protection circuit substrate, the terminal holder fixing a position of the external terminal; and a top case covering the protection circuit substrate and the terminal holder, the top case including holes exposing the external terminal.
Claims17
An external terminal assembly for establishing a connection between a battery pack and an electrical connector of an external device, the external terminal assembly comprising:
- an external terminal, the external terminal being electrically connectable to the electrical connector of the external device;
- a terminal holder on a protection circuit substrate, the terminal holder fixing a position of the external terminal;
- and
- a top case covering the protection circuit substrate and the terminal holder, the top case including holes exposing the external terminal, and the top case being configured to attach to a top surface of a cap plate of a bare cell,
- wherein:
- the terminal holder includes a protrusion,
- the protection circuit substrate includes a groove,
- the protrusion is coupled to the groove, and
- an extending surface of the terminal holder extends below an upper surface of the protection circuit substrate toward the bare cell, the extending surface being different from the protrusion.
A battery pack that is electrically connectable to an electrical connector of an external device, the battery pack comprising:
- a bare cell including a cap plate including a top surface;
- a protection circuit substrate including a protection element mounted thereon for controlling charging/discharging of the bare cell;
- an external terminal assembly electrically connectable to the external device;
- a terminal holder on the protection circuit substrate, the terminal holder fixing a position of the external terminal assembly;
- and
- a top case covering the protection circuit substrate and the terminal holder, the top case including holes exposing an external terminal of the electrode terminal assembly, and the top case being attached to the top surface of the cap plate,
- wherein:
- the terminal holder includes a protrusion,
- the protection circuit substrate includes a groove,
- the protrusion is coupled to the groove, and
- an extending surface of the terminal holder extends below an upper surface of the protection circuit substrate toward the bare cell, the extending surface being different from the protrusion.
