CONNECTING DEVICE FOR POWER SUPPLY

A connecting device for supplying power to equipment in heating devices, particularly, auxiliary vehicle heating devices, which connecting device serves to commonly and centrally supply a combustion motor, a control device, a circulating pump, a solenoid valve, an ignition spark unit, a flame monitoring device, and, if utilized, a preheating device for a burner nozzle assembly. All connections and connecting devices, like plug connectors, are housed and combined in a common, central connecting component which can be secured on a flange of the heating device, and can be attached to a part of the heater housing. Appropriately, the connecting component is designed in the form of a housing and contains the electrical connections to be actuated in the form of printed circuit boards, or the like. In order to avoid connection errors and in order to achieve a low-loss connection, the plug connectors for the devices to be connected are arranged as close as possible to the respective device to be connected; also, a plug connector is provided at the peripheral surface of the connecting component that is accessible via an opening in the flange, which connector is intended for the connection of an external power supply such as that of a vehicle.
