Description

La présente invention concerne un appareil électrique muni de bobines, notamment un transformateur, comprenant une carcasse qui présente au moins une gorge pour bobiner au moins deux enroulements, et deux flasques latéraux portant chacun plusieurs bornes situées sensiblement dans un plan dit de câblage.The present invention relates to an electrical apparatus provided with coils, in particular a transformer, comprising a carcass having at least one groove for winding at least two windings, and two lateral flanges each carrying several terminals located substantially in a plane called wiring.

De tels transformateurs sont connus par exemple d'après les documents EP 751 540 et DE 195 08 695. Les bornes présentent des pièces conductrices qui servent d'une part à connecter les extrémités des fils bobinés sur la carcasse et d'autre part à connecter des extrémités de câbles reliant le transformateur à un circuit "externe" d'alimentation ou de charge. Les pièces de borne assurent donc une connexion directe entre l'enroulement et le circuit externe.Such transformers are known for example from EP 751 540 and DE 195 08 695. The terminals have conductive parts which serve on the one hand to connect the ends of the wires wound on the carcass and secondly to connect cable ends connecting the transformer to an "external" power supply or charge. The terminal pieces thus provide a direct connection between the winding and the external circuit.

Mais il est parfois nécessaire d'insérer électriquement entre l'enroulement et le circuit externe un circuit redresseur, un filtre ou autre composant ou circuit fonctionnel analogue. Les transformateurs connus ont l'inconvénient de ne pas se prêter facilement à cette adjonction, car le raccordement du circuit fonctionnel exige l'interruption de la connexion directe et l'apport d'un câblage spécial et d'une borne supplémentaire pour réaliser une connexion indirecte de l'enroulement avec le circuit externe.But sometimes it is necessary to insert electrically between the winding and the circuit external rectifier circuit, filter or other component or similar functional circuit. The known transformers have the disadvantage of not being easily lent to this addition, because the connection of the functional circuit requires the interruption of the connection direct and the provision of special wiring and an additional terminal to achieve a indirect connection of the winding with the external circuit.

L'invention a pour but de simplifier la conception d'un appareil électrique doté de bobinages, particulièrement d'un transformateur, pour affecter facilement cet appareil à une connexion directe, ou à une connexion indirecte, des bornes d'enroulements avec des circuits externes.The purpose of the invention is to simplify the design of an electrical appliance with windings, particularly of a transformer, to easily affect this apparatus to a direct connection, or an indirect connection, of winding terminals with external circuits.

Selon l'invention, chaque flasque comporte pour les bornes des logements qui sont dotés chacun de deux glissières parallèles au plan des bornes, ou plan de câblage, et décalées l'une de l'autre dans une direction perpendiculaire à ce plan ; la borne comprend deux ailes parallèles d'insertion destinées à être introduites dans les glissières, l'une des ailes, dite aile interne, ayant une excroissance destinée à la connexion du fil terminant un enroulement, l'autre aile, dite aile externe, ayant des éléments de connexion d'un câble externe avec l'enroulement ; les ailes interne et externe présentent chacune une extrémité libre prolongée par une broche de connexion pouvant être connectée à un circuit externe, tel que par exemple un circuit imprimé présentant un circuit fonctionnel de liaison pour assurer l'interconnexion des deux broches. According to the invention, each flange comprises for the terminals houses which are equipped each of two slides parallel to the plane of the terminals, or wiring plane, and offset from each other in a direction perpendicular to this plane; the terminal includes two parallel insertion wings intended to be introduced into the slides, one of the wings, so-called internal wing, having a protrusion for connecting the wire terminating a winding, the other wing, called the outer wing, having connection elements of a cable external with the winding; the inner and outer wings each have one end free extended by a connection pin that can be connected to an external circuit, such as for example a printed circuit having a link functional circuit for ensure the interconnection of the two pins.

Les ailes parallèles d'insertion peuvent avantageusement être prévues sur une pièce de borne en forme de U présentant une âme, de préférence sécable, qui assure la liaison de l'aile externe avec l'aile interne.Parallel insertion wings can advantageously be provided on a piece of U-shaped terminal having a core, preferably divisible, which provides the connection of the outer wing with the inner wing.

Selon l'invention, lorsque les broches de connexion de l'aile interne et de l'aile externe sont connectées entre elles à travers un circuit fonctionnel externe, l'âme sécable de la borne est alors sectionnée.
Selon l'invention, il est donc possible de prendre le courant sur une borne, de le traiter à l'aide du circuit fonctionnel externe et de le renvoyer sur la même borne.
La broche de connexion de chacune des ailes interne et externe est perpendiculaire au plan de câblage pour être connectée au circuit imprimé placé au-dessus du logement de borne.
Selon l'invention, les bornes du transformateur sont polyvalentes et peuvent donc être connectées directement à un circuit externe ou indirectement, à travers un circuit fonctionnel, en montant un circuit imprimé sur les broches de connexion et en sectionnant l'âme sécable des bornes.According to the invention, when the connecting pins of the inner wing and the outer wing are connected to each other through an external functional circuit, the breakable core of the terminal is then cut.
According to the invention, it is therefore possible to take the current on a terminal, to process it with the aid of the external functional circuit and to send it back to the same terminal.
The connecting pin of each of the inner and outer wings is perpendicular to the wiring plane to be connected to the printed circuit board above the terminal housing.
According to the invention, the terminals of the transformer are versatile and can therefore be connected directly to an external circuit or indirectly through a functional circuit, by mounting a printed circuit on the connection pins and by cutting the breakable core of the terminals.

    • Le transformateur selon l'invention comprend, dans l'exemple de réalisation illustré sur la figure 1, un boítier composé d'un corps 10 et d'un socle 11, ainsi que d'un capot de protection non représenté. Le boítier est destiné à loger une carcasse de bobine 20 mieux visible figure 2. Le corps et le socle peuvent former une seule pièce, et la carcasse peut éventuellement former elle-même le corps et le socle. Au lieu d'un transformateur, il pourrait s'agir d'un autre appareil électrique muni d'enroulements à connecter à un circuit d'alimentation ou de charge.
    La carcasse 20 présente (figure 2) une gorge de bobinage 21 pour recevoir les enroulements C de primaire et secondaire et des flasques latéraux 22 qui bordent la gorge 21. Les flasques 21 s'étendent parallèlement à un plan P (perpendiculaire à l'axe de bobinage X) pour contenir latéralement les bobines et porter chacun un bornier 23. Les diverses bornes des borniers 23 sont situées dans un plan de câblage Q perpendiculaire au plan P des flasques. Chaque bornier 23 comprend plusieurs pièces de borne 30 (par exemple ici cinq) disposées chacune dans un logement 24. Les logements 24, délimités par des cloisons d'isolement 25 perpendiculaires aux plans P,Q, s'ouvrent vers l'extérieur par deux faces 24a,24b (latérale et supérieure sur les figures 1 et 2) et présentent une cloison inférieure 24c et une face de butée 24d.    The transformer according to the invention comprises, in the embodiment illustrated in Figure 1, a housing consisting of a body 10 and a base 11, and a protective cover not shown. The housing is intended to house a coil carcass 20 better visible in Figure 2. The body and the base can form a single piece, and the carcass may optionally form itself the body and the base. Instead of a transformer, it could be another electrical device with windings to connect to a power or load circuit.
    The carcass 20 has (FIG. 2) a winding groove 21 for receiving the primary and secondary windings C and lateral flanges 22 which border the groove 21. The flanges 21 extend parallel to a plane P (perpendicular to the axis winding X) for laterally containing the coils and each carrying a terminal block 23. The various terminals of the terminal strips 23 are located in a wiring plane Q perpendicular to the plane P of the flanges. Each terminal block 23 comprises several terminal pieces 30 (for example here five) each arranged in a housing 24. The housings 24, delimited by isolation walls 25 perpendicular to the planes P, Q, open outwards by two faces 24a, 24b (side and top in Figures 1 and 2) and have a lower wall 24c and an abutment face 24d.

    La pièce de borne 30 est en forme de U présentant une aile externe 31, une aile interne 32 et une âme 33 située vers l'extérieur ; l'âme 33 raccorde les extrémités 31a,32a des ailes 31,32 situées vers l'extérieur du logement 24, dites extrémités extérieures 31a,32a. Les extrémités opposées 31b,32b des ailes sont libres et insérées à l'intérieur du logement 24. Ces extrémités libres, désignés ci-après extrémités intérieures 31b,32b, sont dotées de crans 31c,32c pour s'accrocher dans des glissières 26,27 qui sont prévues dans les cloisons des logements 24. Les glissières 26,27 s'étendent selon une direction X' parallèle à l'axe X de la carcasse. A la mise en place d'une pièce de borne 30, ses ailes 31,32 sont introduites par translation latérale selon la direction X' dans les glissières 26,27, jusqu'à s'appliquer contre la face de butée 24d en fond de logement. Des points durs ou des points d'encliquetage peuvent être prévus pour faciliter le maintien des ailes 31,32. L'aile externe 31 offre un trou taraudé 31d pour recevoir une vis de serrage 37 qui permet à l'utilisateur de connecter un câble de liaison C avec un circuit externe, tandis que l'aile interne 32 possède un picot 34 en saillie vers l'extérieur pour connecter par enroulement ("wrapping") l'extrémité d'un fil de bobine c. L'aile 31 peut posséder des éléments de connexion différents de la vis 37 - par exemple cage élastique ou fourchette - si l'on souhaite avoir une borne à serrage élastique ou à dégagement d'isolant.The terminal piece 30 is U-shaped having an outer flange 31, an inner flange 32 and a core 33 located outwardly; the core 33 connects the ends 31a, 32a of the wings 31,32 located outwardly of the housing 24, said outer ends 31a, 32a. The opposite ends 31b, 32b of the wings are free and inserted inside the housing 24. These free ends, designated hereinafter inner ends 31b, 32b, are provided with notches 31c, 32c for catching in the slideways 26, 27 which are provided in the partitions of the housing 24. The slides 26,27 extend in a direction X 'parallel to the axis X of the carcass. At the establishment of a terminal piece 30, its wings 31,32 are introduced by lateral translation in the direction X 'in the slides 26,27, until against the abutment face 24d at the bottom of housing. Hard points or snap points can be provided to facilitate the maintenance of the wings 31,32. The outer flange 31 has a tapped hole 31d for receiving a clamping screw 37 which allows the user to connect a connecting cable C with an external circuit, while the inner flange 32 has a pin 34 projecting towards the outside. outside for winding ("wrapping") the end of a coil wire c . The wing 31 may have different connection elements of the screw 37 - for example elastic cage or fork - if it is desired to have an elastic clamping terminal or insulation release.

    Des broches 35,36 sont prévues aux extrémités intérieures 31 b,32b des ailes 31,32. Ces broches se dressent transversalement aux ailes pour traverser une fente 24e du logement 24. En présence d'un circuit imprimé 28 comportant un circuit fonctionnel 29 à composants actifs ou passifs, les broches peuvent pénétrer dans des trous du circuit imprimé afin d'y être soudées et d'être ainsi reliées au circuit 29 ; une telle connexion permet d'insérer entre l'enroulement (aile 32 et picot 34) et le circuit externe (aile 31) le circuit fonctionnel 29.Pins 35,36 are provided at the inner ends 31b, 32b of the wings 31,32. These broaches stand transversely to the wings to cross a 24th slot of housing 24. In the presence of a printed circuit 28 comprising a functional circuit 29 to active or passive components, the pins can enter holes in the circuit printed in order to be welded and thus be connected to the circuit 29; such a connection allows insertion between the winding (wing 32 and pin 34) and the external circuit (wing 31) the functional circuit 29.

    De manière très simple, on utilise donc une même pièce de borne 30, qu'il y ait lieu ou non de la connecter au circuit imprimé 28. En cas de connexion au circuit fonctionnel 29 du circuit imprimé 28, l'âme 33, qui présente par exemple deux jambages 33a de liaison, est sectionnée (figures 7 et 8). La coupure de l'âme 33 s'effectue selon les cas à la fabrication ou sur le lieu d'utilisation. Les jambages sectionnés 33b peuvent être rabattus comme indiqué figures 7 et 8 pour respecter une distance d'isolement suffisante entre les parties subsistantes de l'âme. En l'absence de connexion, les broches 35,36 ne traversent pas de trous du circuit imprimé, ou bien traversent ces trous sans connexion. L'âme 33 possède comme indiqué figure 4 deux jambages encadrant le picot 34, mais on peut aussi prévoir une âme 33 à un seul jambage. Les broches sont obtenues par pliage d'une partie découpée des ailes ou par rapportées et emmanchées dans des évidements des ailes 31,32, ceci n'étant pas l'objet de l'invention.In a very simple way, we therefore use the same piece of terminal 30, whether there is place or not to connect it to the circuit board 28. When connected to the functional circuit 29 of the printed circuit 28, the core 33, which has for example two connecting legs 33a, is sectioned (Figures 7 and 8). The cutting of the core 33 is carried out according to the cases to the manufacture or at the place of use. The sectioned legs 33b can be folded down as shown in Figures 7 and 8 to respect a sufficient isolation distance between remaining parts of the soul. In the absence of a connection, the pins 35,36 do not cross no holes in the printed circuit, or through these holes without connection. The soul 33 has as shown in Figure 4 two jambs framing the pin 34, but we can also provide a soul 33 to a single leg. The pins are obtained by folding a part cut out of the wings or by inserts and fitted into recesses of the wings 31,32, this not being the subject of the invention.

    Dans une variante de réalisation un peu moins simple (figures 9 et 10), on utilise une pièce 30 en U à ailes 31,32 dépourvues de broches en cas de connexion directe, et deux pièces séparées en forme de L comprenant les ailes 31,32 et leurs broches respectives 35,36 en cas de connexion indirecte. Dans l'un et l'autre cas de connexion, les ailes 31,32 sont introduites selon le plan de câblage Q dans les glissières 26,27 qui sont ménagées dans les cloisons des logements 24.In a slightly less simple variant embodiment (FIGS. 9 and 10), a U-shaped wing piece 31,32 without pins in case of direct connection, and two separate L-shaped parts including wings 31,32 and their respective pins 35,36 in case of indirect connection. In either case of connection, the wings 31,32 are introduced according to the wiring diagram Q in the slides 26, 27 which are arranged in the bulkheads of dwellings 24.

    On constate que le dispositif de l'invention permet d'associer ou non un circuit fonctionnel à un appareil muni de bobinages, en conservant une carcasse inchangée et sans modifier le câblage, grâce à des pièces de borne inchangées ou facilement adaptées.It can be seen that the device of the invention makes it possible to associate or not a functional circuit to a device equipped with windings, keeping a carcass unchanged and without modifying the wiring, thanks to unchanged or easily adapted terminal parts.
