Supporting device for mounting a magnetic core on a printed circuit card

摘要

The invention relates to a supporting device for a magnetic core, a coil arranged on the core and an adjusting screw for changing the inductance of the coil. This complete unit is intended to be mounted on a printed circuit card with the supporting device being a holder for the adjusting screw and providing electrical insulation between the core and the printed circuit card. The supporting device is designed as a circular disc with an upright standing projecting part which is provided with an inner thread in which the adjusting screw can be inserted for adjusting the inductance of the coil. When mounting a unit consisting of a core, a coil, an adjusting screw and a supporting device, on a circuit card printed on both sides, the circular disc of the supporting device provides electrical insulation between the core and the printed circuit card.
