Title
(EN) CHARGE CABLE DEADZONE MITIGATION
(FR) ATTÉNUATION DE ZONE MORTE DE CÂBLE DE CHARGE
Abstract
(EN)
A charging cable is configured to rotate freely while attached to a cable plug on a chargeable device. The plug has contact pads separated by an insulator, and the matching cable head has pins for contacting the pads of the plug. There may be a 'deadzone' position where one or more pins of the cable head rest of the separator and do not make contact with the charge pads on the cable plug. The examples include pins in the cable head for redundant charging paths that are complimentary such that only one of the power paths will be on at any given time. When the cable enters a position where one of its power paths is resting on the "deadzone", circuitry in the cable will over to the second power path which will be capable of providing power to the device.

Selon la présente invention, un câble de charge est configuré pour tourner librement tout en étant fixé à une fiche de câble sur un dispositif chargeable. La fiche a des plots de contact séparés par un isolant, et la tête de câble correspondante a des broches destinées à venir en contact avec les plots de la fiche. Il peut y avoir une position de " zone morte " dans laquelle une ou plusieurs broches de la tête de câble reposent sur le séparateur et ne sont pas en contact avec les plots de charge sur la fiche de câble. Les exemples comprennent des broches dans la tête de câble pour des trajets de charge redondants qui sont complémentaires de telle sorte qu'un seul des trajets d'alimentation sera actif à tout moment. Lorsque le câble entre dans une position dans laquelle l'un de ses trajets d'alimentation repose sur la " zone morte ", des circuits dans le câble arriveront vers le second trajet d'alimentation qui pourra fournir de l'énergie au dispositif.
