Design of a connection system for charging batteries of a vehicle, according to the invention comprises a head (1) connected with a lifting mechanism ( 3 ) through a ball-and-socket joint ( 2 ). The head ( 1 ) of basically prismatic shape is formed by mechanically connected dielectric holders of a PE contact segment ( 1a ), a positive pole high-current contact segment ( 1b ), a negative pole high-current contact segment (1c ) and a communication contact segment ( 1d ), and inside each holder respective electrical brushes ( 1as , 1bs , 1cs , and 1ds ) are mounted slidably on springs ( S ). The electrical brushes ( 1as , 1bs , 1cs , and 1ds ) in their extreme positions protrude from the holder surfaces, furthermore the brushes ( 1as ) of the PE contact segment ( 1a ) protrude from the top surface of the head ( 1 ) , whereas the brushes ( 1bs ) of the positive pole high-current contact segment ( 1b ), the brushes ( 1cs ) of the negative pole high-current contact segment ( 1c ) and the brush ( 1ds ) of the communication contact segment ( 1d ) protrude from two opposite side surfaces of the head. The platform ( 4 ) is constituted by a body ( 4a) inside which at least one dielectric strip ( 4b ) is mounted in parallel to the opposite sides of the body ( 4a ) and slidably in the direction perpendicular to these sides of the body. The strip ( 4b ) is connected with a driving mechanism ( 4c ) mounted in the body ( 4a ) . The strip holds ( 4b ) a negative pole high-current contact rail ( 4b1 ) , a positive pole high-current contact rail ( 4b2 ) , and a communication contact rail ( 4b3 ) . The inner surface ( 4pw ) of the wall which covers the body ( 4a ) from above is electrically conductive. When the strip ( 4b) is in such a position that it is in contact with the side surface of the head (1), the brushes ( 1bs ) of the positive pole high-current contact segment ( 1b ) , the brushes ( 1cs ) of the negative pole high-current contact segment ( 1c ) and the brush ( 1ds ) of the communication contact segment ( 1d ) are in contact with the surface of the positive pole high-current contact rail ( 4b2 ), the surface of the negative pole high-current contact rail ( 4b1 ) and the surface of the communication contact rail ( 4b3 ) , respectively. |
