<p>The winding (11) of this high frequency adjustable coil is mounted on the inside wall of a tube (1). The bottom of the tube is provided with projections (5) that enable the tube to be self-locking when inserted into a panel. At one end of the tube, two elastic cross-pieces (13) are formed during the moulding process and these grip an adjusting screw. The core (19), which has a screw-driver slot at one end, is fastened to the screw and may therefore be moved axially through the winding. This method of mounting permits economical use of the core material.</p> |
