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.

Le système comprend un chargeur de piles (300) et un bloc de piles (100). Lorsqu'on introduit le bloc de piles dans un logement (303) du chargeur de piles (300), un passage (101) de bloc de piles et un rail (305) de chargeur de piles correspondant permettent d'aligner les contacts électriques (201) du bloc de piles avec les contacts électriques (309) du chargeur de piles. Pour assurer une bonne connexion électrique entre les deux séries de contacts (201, 309), une nervure (501) est disposée dans le passage (101) du bloc de piles (100). Cette nervure (501) crée une interférence entre le rail (305) et le passage (101), ce qui a pour effet de créer une force contre le rail. L'interférence est calculée pour créer une force suffisante qui se combine à la force créée par le poids du bloc de piles (100) de façon que la force du bloc de pile égale ou dépasse la force créée par l'ensemble des contacts électriques dans le chargeur de piles.
