The core claimed in the main application consists of staggered or staggered sto3verbiiidun £ en ε-.ui, ait in each leg a zigzag; uuster cilden ,, Lei v.elGhem all legs of the juster diverge in liezu _b on each level of outer surfaces " where the difference in length can be found in each pair of anei: -: a :: derliei.enden ächictiten and leren relative arrangement sirxd, a ^ .ia one layer the other by a kinimum ν cn apart from the thickness of each layer - ■ and preferably by a kinimum of at least four times the thickness - overlapped, and no two connection points in adjacent ones. The legs of the kustwra lie in the same plane, with the two. C-shaped parts: corners of the core can be separated from one another and reassembled around one or more coils without having to dismantle each part.

Of the products contained _6-making invention based on the ^ that the durcii the use of the zigzag pattern ,,, as defined in the preceding paragraph, advantages achieved are erzxeibar by an alternating zigzag pattern in which only alternate leg with respect to the _diverge% -übenea of the layers , with the remaining legs lying in the planes of the layers.

The present invention therefore includes cores and cores Transformers with the same cores as they all in. the main application are described and claimed apart of the change in the pattern »which in the preceding Paragraph is dealt with.

Thereafter, the core according to the present invention staggered butt joints that form a zigzag pattern in each leg, in which all legs of the Pattern diverge with respect to the planes of the layers,

where 'each .. diverging leg is essentially extends completely between opposite ends of adjoining corrugations, which are in planes of layers lie,;, where -furthermore, each diverging leg goes through the ünd is formed by at least five layers, wherein the difference in length between any two adjacent layers and the relative position of the same are such that the one layer the other by a minimum of twice that Thickness of each layer - and preferably to a minimum of at least four times the thickness —.lapped and none two connections in adjacent diverging lines none of the pattern lie in the same transverse plane, the two C-shaped parts of the core being separable from one another and can be reassembled around one or more coils without disassembling any part. After a such reassembly may have the two core parts held together by mechanical gowns, for example by, a printing tape or by an adhesive, as explained below.

. · - '. This extends especially with small cores Zigzag pattern preferably over a half or more each leg of the nucleus. ..

As explained bereits'in the parent application, there may be some difficulties in re-assembly ¹ of the two C-shaped -eile of the core by one or more coils according to separation of the parts occur, due to the thin formation of each, of the layers, and the difficulty of precise lighting. of layers on a layer-by-layer basis at each junction. These difficulties are substantially reduced when a core structure according to the present invention is used,

since the legs, which lie in the plane of the layers, run slightly one above the other. The disassembly and reassembly of the two 'file that a layer space factor is no longer ^u uses as SA ⁰ A nd preferably 88 $ to 94 $ can be further promoted by the fact, and / or by "that the end portions of the layers which form the staggered joints should be lubricated prior to final assembly of the core.

The invention will now be explained in more detail with reference to the drawing reproducing it, for example shows

Fig. 1 is a side elevation of a C-shaped core;

while

Fig. 2 is an enlarged view of part of a the connection points of the core according to Fig * wiedeig.bto

According to Fig. 1, the core has two C-shaped sections 1 and 2 with connection points 3 and 4, which in parallel Legs are formed. The connection points shown 3 and 4 are zigzag connections, so that all layers, such as 5 of the two sections 1 and 2 (see Fig. 2) are nested and offer a mechanical strength that is substantially greater is than that in the known core shape, in which the butt joints between individual layers are all in the lie on the same plane. The pattern of the butt joints is a sawtooth-zigzag (or multiple-N) pattern, namely in that alternating legs 6, 8, 10, 12 and 16 of the pattern with respect to planes parallel to the parallel legs of the two parts run, diverge,

The magnet is eiie η properties of the invention Kerns are essentially the same as those of the C-shaped 'cores as described in the main application and are claimed.

The cores of the present invention can be manufactured by exactly the same method as that of the parent application except for the shape of the zigzag pattern. Alternatively, the individual layers of each half of the core can also be cut to size separately and bent into their required shapes either individually or in groups, '· -.-'

Should difficulties arise after the core has been taken apart, i.e. the two halves of the Kerns have been pulled apart so that a coil placed over one leg of the core and then the core can be closed, these difficulties can be overcome by removing the ends of the layers which form the joints of the core, are lubricated, for example by coating the ends of the Layers with oil or preferably with a relative smooth, tough coating made of a relatively lower material Friction, for example a plastic material as described in more detail in the parent application.

The core halves can be assembled while such a plastic coating is still damp, and the coating material can be given the option after
