Abstract
The system includes a battery charger (300) and a battery pack (100). Upon insertion of the battery pack (100) into a retention area (303) of the battery charger (300), a battery pack channel (101) and a corresponding battery charger rail (305) align the battery pack electrical contacts (201) with the electrical contacts (309) of the battery charger. In order to ensure that a reliable electrical connection is made between the two sets of contacts (201, 309), a compliance rib (501) is disposed within the channel (101) of the battery pack (100). The compliance rib (501) creates an interference between the rail (305) and the channel (101), consequently, creating a force against the rail. The interference is calculated to create a sufficient force in combination with the force created by the weight of the battery pack (100) such that the force of the battery pack meets or exceeds the force created by the set of electrical contacts in the battery charger.
