electrical coupling device for an ultrasonic sensor of a motor vehicle, method for the manufacture of a ultraschallsensors, ultrasonic sensor and motor vehicle

摘要

the invention concerns an electric coupling device (19) for an ultrasonic sensor (4) of a vehicle (1), which is designed.a sensor electronics (14) of the ultraschallsensors (4) with a piezoelement (12) of the ultraschallsensors (4) via a brazed joint electrically to connect and the electrical leitelement (20), and at least one of the leitelement (20) attached to lotkugel (21) which, with the at least lotkugel (21) has a predetermined amount of lötmaterial.the invention concerns also a method for manufacture of a ultraschallsensors (4), an ultrasonic sensor (4) and a motor (1).
