专利摘要:
Device for the formation of a toroidal coil and method for the formation of a toroidal coil. The device comprises an annular guiding piece (1) delimiting a central space (5) for receiving the toroidal magnetic core (4), and comprising a plurality of grooves (2) for the reception of portions of a thread that make up coils (3) of said toroidal coil when arranged around the toroidal magnetic core (4), said grooves (2) being arranged transversely, of base on the basis of the annular guiding part (1), distributed by an inner annular wall ( 1i) separated from each other according to a predetermined arrangement. The method comprises using the device of the invention for the formation of a toroidal coil consisting of one or more windings. (Machine-translation by Google Translate, not legally binding)

Detailed description of some embodiments
25 As illustrated, in particular, in Figures 1a, 1b, 2 and 3, the device for forming a toroidal coil proposed by the first aspect of the present invention comprises an annular guide piece 1 with an inner annular wall 1i which delimits a central space 5 for the housing of the toroidal magnetic core 4, and which comprises a plurality of grooves 2 arranged transversely, from base to
30 base of the annular guide piece 1, distributed by the inner annular wall 1i in an equidistant manner and in parallel, with respect to each other and with respect to the geometric central axis of the annular guide piece 1.
The grooves 2 are provided for the reception of portions of a wire that make up the turns 3 of the toroidal coil as they are arranged around the toroidal magnetic core 35.

The central space 5 is delimited by interstitial portions 6 between grooves 2 of the inner annular wall 1i and has a diameter greater than the outer diameter of the toroidal magnetic core 4.
In the exemplary embodiment of Figs. 1a, 1b and 2, the annular guide piece 1
5 comprises two annular guide parts or half-pieces P1, P2 that can be coupled together by two of their respective opposite bases P1a, P2b, or coupling bases, and each of the annular guide half-pieces P1, P2 comprises, in one end of their respective interstitial portions 6 a plurality of projections 7, to support the toroidal magnetic core 4 by both of its bases or major faces 4a, 4b, ie
10 caught between the projections 7 near the base P1b and the projections 7 near the base P2a (the latter illustrated in Fig. 2 contacting the main face 4a). Adjacent to said projections 7, each of the grooves 2 has a tapered flare 2a that facilitates the entry of the copper wire, in case the winding is carried out using the guide piece 1, or the entrance of the turns 3, for him
15 if the guide piece 1 is used to order the turns 3 of an already wound core. As can be seen in Fig. 1a and 1b, the coupling bases P1a, P2b comprise respective complementary coupling configurations which, for the exemplary embodiment illustrated therein, comprise respective pins 8a and
20 holes 8b arranged in the coupling bases P1a, P2b facing each other, to couple them by the firm introduction of the first 8a in the second 8b, being firmly joined as illustrated in Fig. 2.
For the exemplary embodiment illustrated in Figs. 3, 4 and 5, the annular guide piece 1 is a single piece, and the grooves 2 have the mentioned conical flared 25 defined at one end thereof.
As described in a previous section, the method proposed by the second aspect of the invention comprises using the device of the first aspect to wind a bare magnetic core 2 or, alternatively, to order the turns 3 of a core 4 already wound.
30 In the first case, the core 4 is introduced into the central space 5 of the annular guide piece 1, by directly introducing it on one of its faces for the embodiment of Fig. 3 or in one of the half-pieces P1 , P2, for the embodiment example of Figs. 1a, 1b and 2, after which the other half-piece P2, P1 is arranged on the core 4 trapping it between them. Once the core 4 is arranged in the
35 housing 5, the winding is carried out by introducing the copper wire through one end of one of the grooves 2, taking it out from the other end, passing it
