Patent ID: 7695858

Claim:
A battery pack comprising: a cell unit containing at least one cell; and a first contact unit integrally mounted on and electrically connected directly to the cell unit, said first contact unit further comprising: a housing having multiple slots constructed therein; and a set of first contact elements mounted in each of the slots, said first contact elements constructed to receive second contact elements in electrical contact with said cell unit; and a second contact unit constructed to permit said second contact unit to be mounted on and connected to a circuit board in a battery cavity of an electronic appliance, the second contact unit having second contact elements constructed to engage the first contact elements in electrical contact; wherein each of the slots are constructed comprising two adjoining sides and being open between the two adjoining sides to allow insertion of the second contact elements into the slot in first and second directions, said first and second directions being perpendicular to each other, and further the slot is dimensioned having a first depth in the first direction and a second depth in the second direction; and wherein the second contact elements are constructed with a length for entry between the open sides of the slot; and further wherein the length of the second contact elements is larger than the first or second depths of the slot, thereby permitting the alternate engagement of the first and second contact units to vary displacement of the cell unit from the circuit board in the first and second directions, while maintaining a secure connection.
