Abstract
A battery recharge interconnection system is provided for use on an electric toy vehicle or other load device powered by a rechargeable battery. The interconnection system includes a charger receptacle, operatively connected to a rechargeable battery, covered by a rotatable disc. An opening in the disc permits a plug from an external charger to be inserted through the opening and into the charger receptacle whenever the disc is rotated to a predetermined position in which the opening overlies the receptacle. The rotatable disc is also mechanically coupled to an actuator which engages and operates a cut-out switch or other device. During normal operation of the battery-operated device, the disc is rotated to a first position in which the charger receptacle is obstructed by the disc and the cut-out switch is disengaged. To recharge the device, the disc is rotated to a second position in which the opening in the disc overlies the receptacle, permitting a recharger plug to be inserted in the receptacle. When the disc is in the second position, the cut-out switch is engaged, preventing operation of the device. A current protection fuse in the charging circuit is also disclosed.
