Electric heating device for a motor vehicle

摘要

An electric heating device for a motor vehicle includes at least one PTC heating element with contact metal sheets extending substantially parallel to one another and accommodating between them at least one PTC element, and a printed circuit board. The printed circuit board has formed therein at least one opening through which a contact tongue projects. The contact tongue serves to establish an electric connection between the PTC heating element and the printed circuit board. For providing an electric heating device having a compact structural design, a punched-out connection piece connected to a conductor path of the printed circuit board in an electrically conductive manner. The connection piece defines a fixing portion which rests on the printed circuit board, and also defines and at least one spring tongue projecting into the opening.

1. An electric heating device for a motor vehicle, comprising:
at least one positive-temperature-coefficient (PTC) heating element with contact metal sheets extending substantially parallel to one another and accommodating between them at least one PTC element, and a printed circuit board having formed therein at least one opening through which a contact tongue projects, the contact tongue being defined by the contact metal sheets and serving to establish an electric connection between the PTC heating element and the printed circuit board, wherein: a connection piece is connected to a conductor path of the printed circuit board in an electrically conductive manner, said connection piece defining 1) a fixing portion which rests on the printed circuit board, and 2) at least one spring tongue projecting into the opening.
