  • Patent number: 9093238
    Abstract: A fuse (10) is proposed for interrupting a voltage and/or current-carrying conductor (12) in case of a thermal fault, having a conductor bar (14) ensuring an electrically conductive connection of the voltage and/or current-carrying conductor during correct operation, said fuse (10) being characterized in that the conductor bar (14) melts upon an increase in temperature above the melting point, and the electrically conductive connection of the voltage and/or current-carrying conductor is interrupted due to inherent surface tension. Also proposed is a method for producing the fuse (10) according to the invention.

  • Publication number: 20100231347
    Abstract: The invention relates to a triggering device (1) for a thermal fuse comprising an actuator (11), which is designed to trigger at a threshold temperature, and a conductive bridge element (6) that is attached and connected to multiple connector points (9) exclusively by means of detachable connecting elements (10) for current flow. According to the invention the connecting elements (1) fully detach the bridge element (6) when a threshold temperature is reached or exceeded so that, in case the actuator (11) is triggered, the bridge element (6) is detached from the connecting elements (10) in order to interrupt the current flow.

  • Patent number: 6879121
    Abstract: A method for controlling an electric drive motor (10) of a motor vehicle adjusting drive by means of applying a variable voltage to it should be improved so that an EMV interference suppression can be inexpensively executed. To this end, a controllable resistor (12, 18, 20, 22) is used, which supplies the voltage applied to the drive motor (10).
