Patent ID: 7815458

Claim:
A power source coupling for connecting two power coupling parts, comprising; a first power coupling part mounted on a first component so as to be longitudinally displaceable, and having a first connecting plate with one or more first power coupling elements, a second power coupling part mounted on a second component so as to be displaceably mounted between a first and a second position, and having a second connecting plate with one or more second power coupling elements which are able to cooperate with the one or more first power coupling elements when the first power coupling part is in the first position, mutually cooperating guiding and centering components provided on at least one of the first and second components and the first and second connecting plates to align the connecting plates relative to one another, and a protective element provided on the first power coupling part so as to be adjustable in position, and which in the first position of the power coupling part covers the first power coupling elements when the second power coupling part is not attached, and in the second position of the power coupling part is in an open position.
