Electromagnetic coupling device for charging an electric motor vehicle

An electromagnetic coupling device for connecting a source of electricity with a receiver, an incoming unit containing at least one secondary coil near a depression in said receiver,

• a supplying unit having a primary coil in a casing therefor, said primary coil adapted to be electromagnetically coupled to said secondary coil when said primary coil is introduced into said depression in an insertion direction, said supplying unit having a leading end in said insertion direction and a trailing end remote from said leading end,
• a first cover pivotally mounted on a first side of said supplying unit at a point between said leading end and said trailing end and rotatable in a plane perpendicular to said insertion direction between a protecting position, wherein said first cover overlies said first side of said primary coil, and an open position wherein said first cover is rotated about said point so that one end thereof is spaced apart from said primary coil, said first cover being urged into said open position from said protecting position by insertion of said primary coil into said depression,
• a second cover pivotally mounted on a second side, opposite said first side, of said primary coil at said point and rotatable in said plane between said protecting position and said opening position, said second cover being urged into said open position from said protecting position by insertion of said primary coil into said depression,
• at least one guide on said receiver adjacent said depression, said guide adapted to contact said first cover and said second cover, whereby said first cover and said second cover are moved from said protecting position to said open position as said supply unit enters said depression.
