| 摘要 |
The invention relates to a protective device for control electronics (2) of a motor vehicle component, in particular of a radiator fan drive, having a thermal protection element (1) disposed in the region between the control electronics (2) and a connecting lead frame (3), said thermal protection element tripping when the temperature in the control electronics (2) rises above a threshold temperature value. The thermal protection element (1) comprises two conductor segments (9, 10) having conductor ends (9a, 10a) that face each other and form an interruption point (11) and having one connecting end (9a, 10b) each, wherein the interruption point (11) is bridged by a fluxing agent (12), the fusion temperature thereof being matched to the threshold temperature value, and wherein one of the connecting ends (10b) of the thermal protection element (1) is connected to a contact (4) of the connecting lead frame (3) and the other connecting end (9b) is connected to a contact (5) of the control electronics (2). |
