Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, den Aufbau und die Montage einer elektrischen Heizeinrichtung zu vereinfachen.Of the The present invention is based on the object, the structure and to simplify the installation of an electric heater.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen enthalten.These The object is solved by the features of claim 1. advantageous Embodiments of the invention are contained in the subclaims.
Dadurch, dass die Einrichtung zur elektrischen Kontaktierung von einer mit einem Schenkel in einer Nut am Rahmenteil gelagerten U-förmigen Kontaktfeder gebildet wird, wird bei einfacher Montage gleichzeitig eine sichere, Toleranzen ausgleichende Halterung der PTC-Heizelemente im Rahmen als auch deren Kontaktierung erreicht. Ein Schenkel der U-förmigen Kontaktfedern greift in die Nut des Rahmenteils ein, während der freie Schenkel der Kontaktfedern federnd an einer Kontaktschicht des PTC-Heizelements anliegt. Vorzugsweise weist dabei der geschlossene Bogen der Kontaktfeder dem PTC-Heizelement in Einschubrichtung entgegen.Thereby, in that the device for making electrical contact with one a leg in a groove on the frame part mounted U-shaped contact spring is formed, at the same time a simple installation, a secure, Tolerance compensating mounting of the PTC heating elements in the frame and reached their contact. A leg of the U-shaped contact springs engages in the groove of the frame part, while the free leg of the Contact springs resiliently on a contact layer of the PTC heating element is applied. Preferably, in this case, the closed arc of the contact spring counter to the PTC heating element in the insertion direction.
Die Rahmenteile können entweder ungleich ausgebildet sein, wobei eines der Rahmenteile zur Aufnahme von zwei gegenüberliegenden Kontaktfedern dient und das andere nur eine Abdeckung bildet, oder zwei gleiche Rahmenteile ergänzen sich komplementär zu einem ganzen Rahmen, wobei dann jedes Rahmenteil eine Kontaktfeder aufnimmt.The Frame parts can either uneven, with one of the frame parts for receiving two opposite ones Contact springs serve and the other forms only a cover, or complete two identical frame parts Complementary to a whole frame, in which case each frame part is a contact spring receives.
Nachfolgend sind Ausführungsbeispiele der Erfindung anhand der Zeichnung beschrieben. Es zeigt:following are exemplary embodiments the invention described with reference to the drawing. It shows:
