Appl. No.:

10/326182

Inventors:

Thinh Nguyen - Alpharetta GA
William Phelps, III - Lawrenceville GA

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H01M 214

US Classification:

429 99, 429129, 429130, 429158, 429159

Abstract:

This invention includes a spacer for a rechargeable battery pack. The spacer is hermaphroditic in that it may be rotated by 180 degrees and attached to itself. The spacer sits between two rechargeable battery cells and includes means for accommodating a circuit board. The spacer facilitates connections between the cells and circuit board by way of welding flexible metal tabs. The spacer allows assembly of a battery pack without the need for hand soldering.

Appl. No.:

12/031672

Inventors:

Thinh T. Nguyen - Alpharetta GA, US
Mark C. Taraboulos - Dunwoody GA, US

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H02J 7/00

US Classification:

320107, 320112, 320114, 320115

Abstract:

A charger and battery combination for recharging batteries has a pair of snap arms for retaining a battery within the pocket of the charger. When the battery is inserted into the charger pocket, the snap arms provide a downward force against the battery, thereby ensuring a sound electrical connection between the battery and electrical contacts disposed within the pocket. In one embodiment, the charger pocket includes a pair of channel apertures in which the snap arms are placed. Upon battery insertion, a flex member of the snap arm deflects, thereby allowing a mating feature of the battery to pass. When the battery is fully inserted, a coupling member of the snap arm exerts a force against the battery, thereby pushing the battery towards the bottom of the pocket.
