Definitions

  • the invention relates to an electromagnetic device such as an electrical transformer, of the type comprising a carcass in two parts each provided with a tubular body, the body of one of the two parts being disposed inside the body of the other, this internal body being adapted to receive between its internal walls a segment of magnetic circuit, and the part comprising the external body being provided with at least two returns being made on either side of a another segment of the magnetic circuit, substantially in the extension of the interior walls of the interior body also facing each other.
  • the invention relates more particularly to a device for holding in place the magnetic circuit segments.
  • This two-part design is advantageous in that it makes it possible to produce the two primary and secondary windings independently of one another, and, consequently, to provide, for the same type of carcass, a range of primaries and a range of secondaries which can be combined according to a large number of distinct combinations meeting the individual wishes of users, industrialists or individuals.
  • the carcasses do not allow the transformer connection wires to be taken out to external circuits either on the same cheek (on one edge of the cheek for the primary and on the opposite edge for the secondary) as on different cheeks (but on edges on the same side, one being assigned for example to the primary and the other to the secondary).
  • the invention aims to remedy these drawbacks and for this purpose relates to an electromagnetic device such as an electrical transformer of the kind comprising a carcass in two parts each provided with a tubular body, the body of one of the two parts being disposed inside the body of the other, this interior body being adapted to receive between its interior walls a segment of magnetic circuit, and the part comprising the exterior body being provided with at least two returns being made opposite -vis on either side of another segment of the magnetic circuit, substantially in the extension of interior walls of the interior body also being opposite, device characterized in that at least one of said interior walls facing each other and at least one of said returns are provided with lips for maintaining their respective magnetic circuit segment.
  • an electromagnetic device such as an electrical transformer of the kind comprising a carcass in two parts each provided with a tubular body, the body of one of the two parts being disposed inside the body of the other, this interior body being adapted to receive between its interior walls a segment of magnetic circuit, and the part comprising the exterior body being provided with at least two returns being made opposite -vis on
  • cheeks linked to the external body are each provided on one edge with a plurality of passage slots for connection wires of a winding carried by this external body, the two edges provided with a plurality of slots being near opposite walls of the body, and an outer cheek connected to the inner body is provided in its edge placed against an edge provided with slots of the other carcass part, with a notch freeing said slots, at in its opposite edge, a plurality of slots partially clearing the space between the two bodies for the passage of connection wires of a winding carried by the inner body.
  • two cheeks linked respectively to the inner body and to the outer body are placed one against the other, and these two cheeks have latching means constituted by pins and opposite holes, said nipples of one cheek being snapped into the holes of the other cheek, which allows rapid and practical assembly of the two parts of the carcass.
  • the carcass shown in the drawings is intended for an electromagnetic device such as an electrical transformer. It is made in two parts A, B each provided with a tubular body having a cross section of generally rectangular shape and with two cheeks extending in a plane perpendicular to the central axis common to the two tubular bodies, each at one end of said body.
  • the tubular body 1 of one of the two parts has an outer straight section of smaller dimensions than the inner straight section of the tubular body 2 of the other part so that it can be housed inside this body 2.
  • Part A having a body 1 of smaller dimensions than those of the body 2 of part 8, is provided with two cheeks 3, 4, of generally rectangular shape extending only towards the outside of the body 1, of which l one has external dimensions barely smaller than those of the internal cross section of the body 2, so that this cheek can also be housed inside, and can be guided there during the fitting of the two bodies, with very little play;
  • the other cheek 4 has a substantially larger dimension, and here its dimensions are greater than those of the outer section of the body 2;
  • the small cheek 3 comprises, perpendicular to its plane, two parallel returns 31 extending two opposite walls of the body 1 so that the faces facing the returns 31 continuously extend the internal faces also facing -vis of these opposite walls.
  • Part B is provided with two cheeks 5, also generally rectangular in shape; the cheek 5 extends both towards the inside and the outside of the body 2, so that it can serve as a stop for the corresponding cheek 3 of part A; however, the internal dimensions of the cheek 5 are not inferior to the corresponding dimensions of the internal section of the body 1, so as not to limit the dimensions of the stack more than the latter.
  • the two corresponding edges of the cheek 5 are even spaced a distance slightly greater than that separating the external faces of these returns 31, so that these can be nested inside the cheek 5; the length of the returns 31 is made sufficiently short so that they do not exceed the plane of the external face of the cheek 5; the other cheek 6 extends only towards the outside of the body 2; here it has external dimensions identical to those of the cheek 5 and serves as a stop for the corresponding cheek 4 of the body 1; in addition, it comprises a housing for this cheek 4, in order to prevent any transverse movement of the cheek 4 of the part A by radport to the cheek 6 of the part B, this housing being formed thanks to the presence of a peripheral rim 61 produced on the periphery of the cheek 6.
  • Each of the two parts A, B constituting the carcass is intended to serve as a support for a winding wound around its body 1, 2, between its cheeks, which serve to maintain the winding in position.
  • part A having a body 1 of smaller dimensions can receive for example the primary of a transformer, and part B receive the secondary (or vice versa).
  • part A can also receive and immobilize, inside its body 1, the central branches of stacked E-sheets, by clamping them effectively, the internal face of one of the walls of the body has oblique lips 14 deformable extending longitudinally, parallel to the central axis of the carcass; the wall of the body which includes such lips is one of the two walls which is parallel to the stacked sheets, while the walls which are extended by returns 31 intended to be fitted inside the cheek 5 of the other part B are the walls perpendicular to said sheets.
  • the cheek 5 of part B which serves as a stop for the small cheek 3 of the part A comprises, on two opposite edges of its four edges, perpendicular to its plane, two respective parallel returns 51, one of which is provided with deformable lips 15; these returns 51 are located in the extension of the two opposite walls of the body 1, one of which is provided with lips 14, and the faces being made opposite these returns 51 continuously extend the internal faces also being made vis- opposite these two opnosed walls; the lips 15 are arranged obliquely and extend longitudinally, parallel to the central axis of the carcass.
  • That of the returns 51 which includes lips 15 is that which is in the extension of the wall of the body 1 itself comprising lips 14.
  • the lips 14, 15 of the two parts A, B can be in the extension of each other . It is also possible to provide lips on two opposite walls of the body 1 and on the two cheek returns 5.
  • the slope of the lips 14, 15 notably facilitates the insertion of the stacks of sheets, which are at the end of this insertion, maintained independently, which makes it possible to accept possible differences in thickness between the stack of sheets in E and stacking straight bars.
  • the number of lips of each part of the carcass (here, there are two on each) is preferably even, the lips then being arranged symmetrically with respect to the longitudinal axis of the internal face of the aroi or of the return on which they are made.
  • the large cheek 4 of part A of the carcass provided with an internal body 1 has, in two opposite edges of its four edges, openings for the passage of the connection wires of the windings.
  • One of these openings is made for example in the edge corresponding to the wall provided with oblique lips (or the opposite edge), in the form of a notch 10 extending over almost the entire length of this edge (without any however reach the ends); the height of this notch 10 is such that, when the two parts A, B are fitted. it does not release the space between the bodies 1, 2, at least partially occupied by a winding.
  • the edge opposite to the previous one it is provided, in the manner of a comb, with a plurality of slots 11 (here five slots) extending parallel to each other from the outer edge of this boid to the outer face of the body wall 1.
  • the two cheeks 5, 6 of part B are provided, in one of their edges only, in the manner of a comb, with a plurality of slots 12 (here five slots) extending parallel to each other. others from the outer edge of this edge to the outer face of the wall of the body 2;
  • the split edge of the cheek 5 is one of the two edges having a return 51 in the extension of a wall of the body 1
  • the split edge of the cheek 6 is that which is located on the same side as the opposite wall of the body 1, so that this split edge of the cheek 6 is that which is intended to serve as a stop at the edge of the large cheek 4 of the part A carrying a notch 10.
  • the four edges of the small cheek 3 of part A, B and the other two opposite edges of the large cheek 4 do not have such openings.
  • three edges of each of the cheeks 5, 6 of part B do not have either. It will be noted that, given the presence or absence of openings on the edges of the cheeks, and the shape of these openings, all the cheeks are asymmetrical with the exception of the small cheek 3 of part A.
  • the cheek 5 of part B is provided with ribs 52 perpendicular to its plane and to said returns 51, extending in a triangle from the end of the return to the end of the edge who wears it; with regard to the split edge of this cheek, the ribs extend parallel to the slots 12, at the rate of a rib between two successive slots, with an additional rib at each of the two ends of the comb so that each slot is between two ribs 52; thus the teeth delimited by the slots 12 also have better mechanical resistance, and the electrical insulation between the wires of the windings and especially between the connection terminals is increased.
  • edges provided with openings in the cheek 4 of part A have a return 41 perpendicular to the plane of the cheek and in the extension of the body 1, and ribs 42 arranged in the same way as the ribs 52 of the cheek 5 also so that each opening is between two ribs 42.
  • the wires of the body winding 1 and those of the body winding 2 intended to be connected to external circuits can be taken out either on the same cheek 4 of part A, or on the cheek 4 for the wires. of the winding of the inner body 1 and on the cheek 5 for those of the winding of the outer body 2.
  • terminals such as screw terminals can be mounted in correspondence with each of the slots 11, 12.
  • Latching means are provided on the two parts A, B of the carcass, symmetrically.
  • These snap-fastening means consist of pins 16 provided on the cheek 6 projecting outwards from part B of the carcass, and holes 17 provided in the cheek 4 of part A, symmetrically with respect to the central axis of the carcass.
  • the two parts A, B are therefore fitted one into the other and snapped on at the end of the stroke, so as to have either the primary and secondary outputs on the same cheek and isolated from each other. to the other, which makes it possible to route non-insulated wires from one winding to the other to access connection terminals without contact possible between them and even with perfect insulation (case of transformers in vertical mounting), either primary and secondary outputs on two different cheeks / but in the same alignment with, of course, always the same perfection of isolation (case of flat transformers).
