Pushable transport cart and pushable transport cart system

A pushable transport cart system comprising a plurality of interconnected pushable transport carts, the pushable transport carts each comprising

• at least one electric and/or electronic device,
• an electric storage device, which is connected to the electric and/or electronic device for supplying electric power, and
• a mechanical connecting device, by which the pushable transport cart can be mechanically connected to another pushable transport cart and/or a stockage and/or charging station, wherein
• the mechanical connecting device and an electric connecting device are combined and
• the mechanical connecting device and the electric connecting device are configured in such a way that when the mechanical connecting device of one pushable transport cart is mechanically connected to the mechanical connecting device of the other pushable transport cart or the stockage and/or charging station, at least one electric connection is created between the electric connecting device of the pushable transport cart and the electric connecting device of the other pushable transport cart or of the stockage and/or charging station, the electric connection being configured for at least one of an electric power exchange, a signal exchange or a data exchange, and
• a further electric connecting device is provided at a distance from the electric connecting device and the mechanical connecting device,
• wherein the electric connecting device and the further electric connecting device form at least one electric circuit, wherein the electric circuit comprises a feed line, which is provided by the electric connecting device and leads from the stockage and/or charging station or the other pushable transport cart to the pushable transport cart, and a return line, which is provided by the further electric connecting device and leads back from the pushable transport cart to the stockage and/or charging station or to the other pushable transport cart, wherein the electric circuit is only closed when both the electric connecting device and the further electric connecting device establish a connection to the stockage and/or charging station or to the other pushable transport cart.
