    摘要: The invention relates to an ultrasonic transducer with a pot-shaped oscillating element, which is mounted in a transducer housing and which bears a piezoelectric disc on its bottom. The invention simplifies the electric contact-making between the connecting leads and the oscillating element or the piezoelectric disc and makes this process more suitable for automated manufacturing. The invention consists of contact springs which are not soldered or caulked with the above-mentioned elements, but only tact them resiliently. Improvements are achieved through an essentially cylinder-shaped connecting element, to which the contact springs are fastened by casting and which can also serve as a damping element.
