Windings for electro-magn. Induction coils The invention relates to the winding of closed cores for el.-magn. Induction coils with very dense wrapping; particularly suitable for toroidal cores and all possible magnetic materials. Application e.g .: radio interference suppression.

So far, toroidal cores for this application have been mostly done manually with great effort, with electrical conductors - predominantly made of copper - in one Pieces wound per spool. The effort increases considerably:

the larger the conductor cross-sections to be wound; the greater the number of turns required;

the higher the required electrical strength of the turns and / or windings to one another and

the smaller the toroidal cores to be wound.

The invention is based on the object of one or more wraps To efficiently manufacture (coils) of toroidal cores that were previously not produced - or only with considerable effort will.

This object is achieved in that the Windings as sections - one section corresponds to one turn - particularly inexpensive and precisely mech. manufactured and can be plugged around the core. The shapes and dimensions of the pieces result from the shapes and dimensions of the parts to be wound Magnetic cores. The pitch angle (1) of the sections (2) results from the required for the desired inductance Number of turns. The sections (2) are placed around the core in such a way that the wire end (3) corresponds to the wire end (* f) of the facing the next section and can be connected. Everyone comes for the connection technology for the sections Process in question, which meet the el. Requirements of the finished coil, z. E.g .: welding, soldering, etc.

The beginning and end of a winding (reel) are made from parts of the same shape, dimensions and angles, but with one side as desired long wire ends (3) or (* f) - extension shown in dashed lines - Formed for the electrical connection.

The advantages achieved with the invention are in particular the following:

The sections can be very precisely mech. getting produced
and are particularly suitable for larger conductor cross-sections with small toroidal cores that do not have a winding
made from a connected conductor in one piece.

Due to the precise design of the sections, a high, optimal number of turns can be accommodated on small toroidal cores will; at the same time, there is a better, optimal electrical strength of the turns and / or windings with respect to one another available.

All known, appropriate profiles and possible electrical conductor materials can be manufactured as parts,
assembled in the manner described and connected to form a coherent winding.

The sections can easily be made with gauges if necessary
be assembled and connected by assistants.
