Abstract

The coil body (SK) receives a magnetic choke core in the form of a closed yoke and has at least one central wire feed opening and wire guide devices (DF) at its ends for maintaining one or more wire windings (DW1,DW2) provided with radial electrical terminations in a required pattern. The coil body can be provided by an open trough for reception of the choke core fitted with a cover, with a holder (HA1) provided at one or both ends for mounting the coil body in its working position. The central feed opening can be divided by a separation limb (TS). An Independent claim for a choke coil is also included.
