Abstract

A device having a winding configuration, especially a layer-type device having a winding configuration, the winding configuration being accommodated in a winding carrier, the winding carrier being situated between a cover part, particularly by which the winding carrier is covered, and a ferrite layer that has openings, especially gaps, the ferrite layer being mounted on a support that is situated on a base part, support domes being provided, especially being integrally molded and/or shaped, on the base part, which protrude through the openings in the ferrite layer and contact and/or support the winding carrier and/or the cover part.

First claim

What is claimed is:

1. A device, comprising:
a cover part;
a winding carrier;
a winding configuration accommodated in the winding carrier;
a ferrite layer including openings;
a support;
a base part; and
support domes formed in one piece on the base part, wherein:
the support domes protrude through the openings in the ferrite layer and support at least one of the winding carrier and the cover part,
the winding carrier is disposed between the cover part and the ferrite layer, and
the ferrite layer is mounted on the support that is situated on the base part.

2. The device as recited in claim 1 , wherein:
the device is a primary-winding configuration,
the support is a support layer,
the openings are gaps, and
the winding carrier is disposed between the cover part and the ferrite layer by that part of the cover part by which the winding carrier is covered,
the support domes are one of integrally molded and shaped.

3. The device as recited in claim 1 , wherein the cover part, the winding carrier, the support, and the base part are made of electrically insulating material.

4. The device as recited in claim 1 , wherein at least one of:
the base part is able to be placed on a floor and has a wall thickness which increases within a mounting surface on the floor from an outside toward a middle of the mounting surface,
the base part resting on a level floor at least one of is mound-like and has an arched structure, and
the base part has a shape of a truncated pyramid.

5. The device as recited in claim 4 , wherein at least one of:
the floor is a level, horizontally extending floor area,
the wall thickness includes one of a vertical thickness and a vertical height,
the base part has an arched shape and water is able to drain off toward the outside, and
a maximum of the arched shape, corresponding to a maximum vertical height above the floor, is centrally located in the base part.

6. The device as recited in claim 1 , wherein at least one of:
the cover part is screw-connected with the aid of screw anchors joined to the floor with at least one of a form-locking and force-locking to the floor on which the base part rests,
the cover part is joined imperviously to the base part by pressing an edge section, corresponding to a collar edge, of the cover part onto the base part, including by pressing on an area going around at an outer edge of the base part, and deforming the base part, and
a deformation area of the base part going around at the outer edge of the base part is pressed against the floor by at least one of the screw anchors and a weight force of the base part.

7. The device as recited in claim 1 , wherein the winding wire of the winding configuration is joined to the winding carrier by being clipped into corresponding depressions in the winding carrier.

8. The device as recited in claim 1 , wherein:
the base part has a centrally located opening in which an electronic component is placed,
winding-wire ends of the winding configuration are connected electrically to connection devices of the electronic component, and
the opening is through-going at least one of parallel to an extension direction of the support domes and vertically to the extension direction.

9. The device as recited in claim 1 , wherein:
the openings and the support domes are disposed in an evenly-spaced, planar grid pattern,
the grid pattern is formed of mutually parallel rows set apart evenly from each other,
a spacing within the respective row being uniform,
a distance to the next-adjacent opening in the row corresponding in each case to a grid constant,
rows next-adjacent to each other in each instance having an offset, in an extension direction of the row, of one-half grid constant relative to each other, and
the openings and the support domes are rectangular.

10. The device as recited in claim 1 , wherein:
the winding configuration has cross-overs of winding wires that are at least one of implemented and disposed in respective depressions in the winding carrier, and
a vertical level of the depressions rises monotonically from an outer edge of the winding carrier toward a center, so that water penetrating into the device is able to drain off from an inner area toward the outer edge.

11. The device as recited in claim 1 , wherein:
the ferrite layer is constructed essentially of homogeneous, cuboidal ferrite plates,
the ferrite plates are disposed in rows that are parallel to each other, with the ferrite plates in rows directly adjacent to each other having an offset,
at least two ferrite plates are situated between each two gaps for a passage of the support domes, and
shorter ferrite plates are located at an end of the row in comparison to the homogeneous ferrite plates.

12. The device as recited in claim 1 , wherein the winding carrier and the base part are realized in one piece.

13. The device as recited in claim 1 , wherein:
the winding configuration has part-windings,
one turn of a second part-winding is assignable to each turn of a first part-winding in such a way that between each turn of the first part-winding and a turn of the first part-winding following it, an intermediate area and an area difference are enclosed which is equal to the intermediate area enclosed between the two respective assigned turns of the second part-winding,
the area enclosed by the turn of the first part-winding in each instance being equal to the area enclosed by the respective assigned turn of the second part-winding, and
each turn of the first part-winding has a number of cross-overs with the assigned turn of the second part-winding.

14. The device as recited in claim 13 , wherein:
the intermediate area has two portions, a first portion being located on longitudinal sides, and another portion on transverse sides of the respective turn,
given a rectangular implementation of each turn, the area difference is split up uniformly in the transverse direction and uniformly in the longitudinal direction, and
a ratio of the first and the other portions correspond to a ratio of length to width of a rectangle.

15. The device as recited in claim 1 , wherein:
the winding configuration has part-windings,
one turn of a second part-winding is assigned to each turn of a first part-winding,
each turn of the first part-winding has a number of cross-overs with the assigned turn of the second part-winding, and
an area value of an area wrapped around in each case by the turn of the first part-winding is equal to an area value of an area wrapped around by the respective assigned turn of the second part-winding.

16. The device as recited in claim 15 , wherein at least one of:
the first part-winding and the second part-winding are placed in such a way that, by an imaginary rotation through 180°, the first part-winding is transferable into the second part-winding,
