Patent ID: 8038478

Claim:
A cordless electrical connecting comprising: A docking unit and a single key, which when in mechanical contact interacts with each other for transmission of electric current and/or energy, wherein said pins can be pushed further into the docking unit, wherein said pins are arranged for movement in the same direction, wherein said pins are arranged in such a way that when the key is advanced towards the front of the docking unit, the key will come into mechanical contact with exactly one of the pins and push the contacted pin further into the docking unit, after which, when the contacted pin is pushed in far enough, electrical contact will be established between the key and the docking unit through conducting surfaces on the key and inside the docking unit, for transmission of electric current and/or electric energy, the pins being arranged in a pattern with electrically isolating intermediate parts located between the pins, so that the intermediate parts form parallel canals in which the pins are displaceable, the intermediate parts, at fee front surfaces, comprising guiding surfaces defining an exterior perimeter of each canal and guiding the key towards an adjacent pin of each canal so that the key enters exactly one of the canals and comes into mechanical contact with exactly one of the pins, and the docking unit further comprising a spring actuated inelastic band, wherein said inelastic band controls the pins so that when the one pin has been pushed in by the key, the remaining pins, in a row include the one pin pushed in by the key, are prevented from being pushed in.
