BACKGROUND OF THE INVENTION The present invention relates to the design of chokes with a vertical axis for DC power circuits.

So far, chokes have been designed for these circuits in particular and with higher currents, the winding of which is predominantly composed of many plate coils with a horizontal or vertical axis, which is fastened by clamping elements of various shapes and designs. These tightening elements are, for example, frontal starlets, usually with five or six arms, at the points of which there are holes through which the tightening bolts pass along the outer circumferential walls of the windings.

Other known elements for fastening the choke windings are end rings, strips or frames axially tightened by several bolts on one or both circumferential walls of the winding. The disadvantage of all these known constructions is their considerable material consumption and laboriousness.

In the case of a suitably arranged winding, and in particular when using wide strips or sheets in the manufacture thereof, the massiveness of the known fastening structures is disadvantageous and ineffective for the above-mentioned circuits.

These disadvantages are overcome by the design of the vertical-axis chokes for the DC power circuits of the invention, wherein the cylindrical choke of the choke is axially retracted between two at least triple pointed starfish.

It is based on the fact that the only axial tightening element of the coil winding is a central bolt with nuts, one end of which can be fitted with a suspension nut. The front star studs are optionally terminated with feet with horizontal surfaces on the outside, by which the lower star is adjacent to the choke base, and in a possible vertical assembly consisting of several chokes, a spacer intermediate spacer is placed between the horizontal feet of the two adjacent chokes.

The design of the chokes according to the invention is simpler than the known designs, reducing material consumption and manufacturing effort. Another advantage is that, if necessary, it allows an easily assembled vertical arrangement of several chokes one above the other.

In DC power circuits, there are no dynamic forces in the choke operating conditions and therefore their vertical assembly is not demanding, not a special fixation.

In the accompanying drawing, an example of the design of the chokes according to the invention is shown, in which Fig. 1 is a front elevation view of an assembly of two chokes with a partial section, and Fig. 2 is a plan view thereof.

The cylindrical coil 8 of the choke made of aluminum or copper foil is pulled in a vertical axis between two three-armed light-alloy front stars 3 by a single central bolt 8 with nuts χ. ,

Its upper end is extended and, if necessary, provided with a suspension nut 6. The front star 3 may also have a plurality of arms, for example arranged in a cross or the like. These arms or tips are terminated on the outside of the star 3 by raised feet with horizontal surfaces g, by which the lower star 3 is adjacent to the cylindrical base base g.

In a possible configuration consisting of at least two stacked chokes in one vertical axis, a spacer intermediate g is arranged between the horizontal surfaces g of the feet of adjacent chokes 3 of adjacent chokes. This intermediate g consists, for example, of a cylindrical tube whose height is to protect the windings χ of adjacent chokes from interfering with each other.
