Coil former with rounded edges and feed holes in same flange - has undercut holes tangential to outer surface of former cylinder with T=shaped slits for slider

摘要

In the coil former, the windings are bounded by flanges. One of the flanges has an entry and exit hole. The former has a rectangular cross-section with the corners rounded off. They are suitable for manual or machine winding of the oil. The holes (35) in the flange are undercut and run tangentially to the outer surface (31d) of the former (31) which supports the winding. The undercuts (45) are suitable for fixing an iso-slider. The holes in the former are in the form of a T shape slit parallel to the axis. The cut-outs are intended to guide the conductor of the coil.
