Abstract
A charging coupling for connecting a robotic garden tool with a charging device may facilitate the charging of a battery of the robotic garden tool. The charging coupling may include a first charging contact and a second charging contact. The first charging contact may be a charging plate or a charging rod. The second charging contact may be provided with a row of resilient contact bars. The arrangement of the first charging contact and the second charging contact may be configured such that the resilient contact bars are pressed against the charging plate to provide multiple contact points.
