Claim Text:
1. A charging coupling for connecting a robotic garden tool to a charging device, comprising; a first charging contact comprising a contact edge, wherein the first charging contact is disposed on a lateral side of the robotic garden tool; and a second charging contact comprising a row of at least two resilient contact bars for providing multiple contact points between the first charging contact and the second charging contact, the at least two resilient contact bars comprising a contact face and an opposite face, wherein the row of resilient contact bars extends vertically upward and away from a charging station, wherein the first and second charging contacts are configured to establish a charging connection between the contact edge of the first charging contact and the contact face of the second charging contact, in response to the robotic vehicle driving onto the charging station, wherein the second charging contact comprises a base plate and wherein the row of resilient contact bars protrude away from the base plate, wherein the second charging contact forms about a 90 degree angle between the base plate and the row of resilient contact bars, and wherein the base plate comprises one or more mounting holes on a first side of the about 90 degree angle and a second side of the about 90 degree angle has a common direction of extension as the row of resilient contact bars.
