## Abstract

A rechargeable battery pack including a cap cover through which a protection element may be easily mounted and a coupling terminal which is integrally manufactured when forming the cap cover includes: a bare cell having an electrode terminal; a cap cover coupled to a leading side of the electrode terminal of the bare cell, and on which a through hole is formed; a first coupling terminal attached to an external side of the cap cover; and a protection element accommodated in the cap cover, electrically connected to the electrode terminal via a first coupling lead, and electrically connected to the first coupling terminal via the through hole by a second coupling lead.

## Claims

### Claim 1

A rechargeable battery pack comprising:
a bare cell having an electrode terminal;
a cap cover coupled to a leading side of the electrode terminal of the bare cell, a portion of said cap cover being perforated by a through hole;
a first coupling terminal attached to an external side of the cap cover, a side of said first coupling terminal being in correspondence with the through hole; and
a protection element accommodated within the cap cover and electrically connected to the electrode terminal via a first coupling lead, and electrically connected to the first coupling terminal via the through hole by a second coupling lead.

### Claim 2 (depends on 1)

The rechargeable battery pack as claimed in claim 1, wherein the first coupling terminal is integrally formed with the cap cover.

### Claim 3 (depends on 1)

The rechargeable battery pack as claimed in claim 1, wherein one of the first coupling terminal and the second coupling lead is bent to penetrate through the through hole.

### Claim 4 (depends on 1)

The rechargeable battery pack as claimed in claim 1, wherein the first coupling terminal includes a flat section and a recessed groove section which is bent to be exposed to an inner side of the cap cover via the through hole from the flat section.

### Claim 5 (depends on 4)

The rechargeable battery pack as claimed in claim 4, wherein the second coupling lead is electrically connected to the recessed groove section exposed to the inner side of the cap cover.

### Claim 6 (depends on 1)

The rechargeable battery pack as claimed in claim 1, further comprising a second coupling terminal to electrically connect the electrode terminal to the first coupling lead.

### Claim 7 (depends on 1)

The rechargeable battery pack as claimed in claim 1, wherein the cap cover includes an exposed terminal groove arranged at a position corresponding to the electrode terminal.

### Claim 8 (depends on 1)

The rechargeable battery pack as claimed in claim 1, wherein the bare cell further includes a can, and wherein the first coupling terminal is electrically connected to the can of a neighboring bare cell.

### Claim 9 (depends on 8)

The rechargeable battery pack as claimed in claim 8, further comprising a lead plate coupling the first coupling terminal to the can of the neighboring bare cell.

### Claim 10 (depends on 1)

The rechargeable battery pack as claimed in claim 1, wherein a fractional length of one of the first coupling terminal and the second coupling lead comprises a knuckle providing an electrical conductor operationally extending through the through hole.
