摘要： A charging stand is provided including a body having a first surface, and a bump having a top region and one or more sides. The one or more sides extend between the first surface and the top region. The charging stand further includes one or more base contact pins that are coupled to the body. Each base contact pin has an exposed end disposed at a first distance in a first direction from the first surface. The charging stand further includes a bump contact pin extending from the top region of the bump. The bump contact pin has an exposed end disposed a second distance in the first direction from the first surface, the second distance is greater than the first distance, and the first direction is perpendicular to the first surface.
