PROTECTIVE DEVICE AND THERMAL PROTECTION ELEMENT, IN PARTICULAR FOR THE CONTROL ELECTRONICS OF A MOTOR VEHICLE COMPONENT
First Claim
1. A protective device, comprising:
- a thermal protection element configured to trip upon a temperature rise above a threshold temperature value;
said thermal protection element having two conductor segments with conductor ends, facing one another at an interruption point, and each of said conductor segments having a connecting end;
a fluxing agent disposed to bridge said interruption point and having a melting temperature adapted to the threshold temperature value.

Abstract
A protective device for control electronics of a motor vehicle component, such as a radiator fan drive, has a thermal protection element between the control electronics and a connecting lead frame. The thermal protection element trips when the temperature in the control electronics rises above a threshold temperature value. The thermal protection element has two conductor segments with conductor ends facing each other and forming an interruption point and one connecting end each. The interruption point is bridged by a fluxing agent, the fusion temperature of which is matched to the threshold temperature value. One of the connecting ends of the thermal protection element is connected to a contact of the connecting lead frame and the other connecting end is connected to a contact of the control electronics.
