a plurality of battery cells;
a case configured to receive the plurality of battery cells therein;
a connector configured to electrically connect the battery pack to a device; and
a printed circuit board (PCB) configured to control operation of the battery pack, the PCB being located inside or outside the case, and the connector being coupled to the PCB,
wherein the connector comprises:
a clip portion configured to form a first contact point at which the connector is configured to electrically contact a device pin when the device pin is inserted into the connector; and
a pair of contact arms, each contact arm having one side connected to a portion of the clip portion, the pair of contact arms being configured to form a second contact point having a distance to the device pin varying in inverse proportion to a distance to the device pin at the first contact point,
wherein the pair of contact arms include a first contact arm connected to a first side of the clip portion and a second contact arm connected to a second side facing the first side of the clip portion,
wherein the first contact arm and the second contact arm do not directly contact each other, and
wherein as a distance between the clip portion and the device pin towards the first contact point decreases, a distance between the pair of arms and the device pin from the second contact point towards the first contact point increases.
