Abstract
The present invention relates to a fastener means for securing a center conductor ( ) in a cavity filter and for enabling the center conductor to be secured mechanically in a stable fashion and with good electric contact between itself and the bottom of the cavity. The inventive fastener means comprises a center conductor and a fastener element ( ) provided integral therewith to form a single-piece structure, which structure may have the form of a screw with the center conductor ( ) as the screw head at one end and screw threads ( ) at the other end. The contact surface between the fastener means and the cavity bottom is surface-treated with a material of low resistivity, such as silver for example.
