ABSTRACT:
An air heater is provided with a connecting case for the power supply and the air to be heated, as well as a heating element attached to the connecting case by means of a carrier. In the connecting housing, the carrier is connected via a plug connection with the connection board for transmitting the heating current. For this purpose, a receptacle angle bracket is provided that can be inserted into the connecting housing and locked in place. The receptacle angle bracket has cylindrical sleeves serving as electrically insulating bushings for the contact pins on the carrier. In order to tap reference voltages for the control device, the contact pins of the plug connection can be connected with the contact tracks of the connection board of the control device by means of rubber-elastic conductive connecting elements. In order to establish the contact, an injection-molded part made of conductive rubber is used that is pressed against the contact points when the connection board is installed in the connecting housing. The air heater is distinguished by its small number of individual components that allow its quick assembly.
