Description
L'invention se rapporte à une connexion électrique, sur une plaque conductrice d'un appareil, pour l'alimentation en courant d'un composant. The invention relates to an electrical connection, on a conductive plate of an apparatus, for the current supply of a component.
Elle se rapporte également à la plaque pourvue de la dite connexion et à l'appareil qu'elle équipe. It also relates to the plate provided with said connection and to the device which it equips.
Pour distribuer du courant électrique à des composants tels des transistors bipolaires (IGBT), des condensateurs ou autres, il est connu de faire appel à des dispositifs de distribution de courant souvent appelés " bus bar comprenant
- au moins deux plaques conductrices notamment en cuivre ou aluminium disposées l'une au dessus de l'autre, dites inférieure et supérieure et isolées les unes des autres par une couche d'un matériau isolant, lesdites plaques ayant des polarités différentes et
- rapportés sur ces plaques, des organes de connexion sur chacun desquels se connecte électriquement un élément de connexion du composant à alimenter.To distribute electrical current to components such as bipolar transistors (IGBT), capacitors or the like, it is known to use current distribution devices often called "bus bars" comprising
at least two conductive plates, in particular of copper or aluminum, placed one above the other, called lower and upper and insulated from each other by a layer of insulating material, said plates having different polarities, and
- reported on these plates, connection members on each of which electrically connects a connection element of the component to be supplied.
Chaque organe de connexion-sur-La-gDa-que-romprend
- un insert tubulaire présentant à l'une de ses extrémités dite extrémité inférieure, une couronne, lequel insert est introduit dans une découpe de la plaque jusqu'à ce que la couronne soit en contact avec la face inférieure de la plaque et
- une bague engagée sur cet insert, après son introduction dans la découpe et venant en appui sur la face dite supérieure de la plaque et
- des moyens d'immobilisation de l'insert et de la bague sur la plaque.Each connection-on-the-gDa-that-romprend
a tubular insert having, at one of its ends, called the lower end, a crown, which insert is introduced into a cutout of the plate until the crown is in contact with the underside of the plate, and
a ring engaged on this insert, after its introduction into the cutout and coming to bear on the so-called upper face of the plate, and
- Means for immobilizing the insert and the ring on the plate.
L'élément de connexion du composant se présente généralement sous la forme d'une pièce métallique prenant appui sur l'insert tubulaire. The connection element of the component is generally in the form of a metal part bearing on the tubular insert.
L'organe de connexion est verrouillé au moyen d'une vis sur l'insert. The connection member is locked by means of a screw on the insert.
Les composants possèdent au moins deux éléments de connexion en saillie sur l'une de leurs faces. The components have at least two connection elements projecting from one of their faces.
Les organes de connexion, qu'ils soient fixés sur la plaque supérieure ou sur la plaque inférieure, sont accessibles depuis la face supérieure de l'empilement de plaques et, à cet effet, au droit des organes de connexion fixés sur la plaque inférieure, la plaque supérieure présente une large découpe autorisant l'accès. The connection members, whether fixed on the upper plate or on the lower plate, are accessible from the upper face of the stack of plates and, to this end, in line with the connection members fixed on the lower plate, the upper plate has a large cut allowing access.
Ces plaques de cuivre sont de grandes tailles pouvant atteindre des dimensions d'un métre de large sur deux mètres de longueur. These copper plates are large sizes that can reach dimensions of one meter wide by two meters in length.
Le courant que transporte ces plaques de cuivre est important et par effet joule provoque des variations de températures qui induisent une modification des caractéristiques géométriques de la plaque par le phénomène de dilatation. The current carried by these copper plates is high and by the Joule effect causes temperature variations which induce a modification of the geometric characteristics of the plate by the phenomenon of expansion.
Outre l'effet joule, les dispositifs équipés de ces "busbars" travaillent dans des plages de température très variables, par exemple, entre moins quarante degrés celsius et plus soixante dix degrés celsius, ce qui augmente encore plus le problème notamment lorsque les composants sont immobilisés sur un support. In addition to the Joule effect, devices equipped with these "busbars" work in very variable temperature ranges, for example, between minus forty degrees celsius and plus seventy degrees celsius, which increases the problem even more when the components are immobilized on a support.
Il en résulte donc ' que,~~ s~i ~ ~~ une ~température prédéterminée, l'entraxe des organes de connexion est égal à l'entraxe des deux éléments de connexion du composant, lorsque la température des plaques varie, il y a modification de l'entraxe entre les organes de connexion sans modification de celui des éléments du composant. It therefore follows that, ~~ s ~ i ~ ~~ ~ a predetermined temperature, the distance between the connecting members is equal to the distance between the two connection elements of the component, when the temperature of the plates varies, there a modification of the distance between the connecting members without modifying that of the components.
Cela provoque donc des contraintes qui tendent à dissocier l'organe de connexion de la plaque et à rompre les bornes du composant. This therefore causes stresses which tend to dissociate the connection member from the plate and to break the terminals of the component.
Outre ce problème de dilatation thermique, les composants ont des tolérances importantes sur le plan des dimensions et lorsqu'ils sont immobilisés sur un support, il faut forcer sur les vis pour obtenir un contact correct avec l'insert tubulaire, d'ou un risque non négligeable de rupture qui s'accroit avec la variation de température. In addition to this problem of thermal expansion, the components have significant tolerances in terms of dimensions and when they are immobilized on a support, it is necessary to force on the screws to obtain correct contact with the tubular insert, hence a risk significant breakage which increases with temperature variation.
L'invention à notamment pour but de remédier à ce problème. The invention in particular aims to remedy this problem.
A cet effet, l'invention a pour objet une connexion électrique sur une plaque conductrice d'un appareil pour l'alimentation en courant d'au moins un composant comprenant un organe de connexion fixé au travers d'une découpe de la plaque, cet organe de connexion comprenant lui même
- un insert tubulaire présentant à l'une de ses extrémités, dite extrémité inférieure, une couronne, lequel insert est introduit dans la découpe de la plaque jusqu'à ce que la couronne soit en contact avec la face inférieure de la plaque et
- une bague engagée sur cet insert, après son introduction dans la découpe et venant en appui sur la face dite supérieure de la plaque et
- des moyens d'immobilisation de l'insert et de la bague sur la plaque, cette connexion électrique étant caractérisée en ce que
- la zone dite d'appui de la plaque sur laquelle est fixée l'organe de connexion se situe dans un plan différent du plan contenant la plaque et cette zone dite d'appui est reliée à la plaque par une zone dite de transition qui absorbe les contraines dues aux variations de dimensions de la plaque et à la tolérance dimensionnelle des composants.To this end, the subject of the invention is an electrical connection to a conductive plate of an apparatus for supplying current to at least one component comprising a connection member fixed through a cutout in the plate, this connecting member comprising itself
a tubular insert having at one of its ends, called the lower end, a crown, which insert is introduced into the cutout of the plate until the crown is in contact with the underside of the plate, and
a ring engaged on this insert, after its introduction into the cutout and coming to bear on the so-called upper face of the plate, and
means for immobilizing the insert and the ring on the plate, this electrical connection being characterized in that
- the so-called support zone of the plate on which the connection member is fixed is located in a plane different from the plane containing the plate and this so-called support zone is connected to the plate by a so-called transition zone which absorbs the constraints due to variations in plate dimensions and the dimensional tolerance of the components.
L'invention a également pour objet la plaque pourvue de la dite connexion ainsi qu'à l'appareil. The invention also relates to the plate provided with said connection and to the device.
L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif, en regard du dessin ci-annexé qui représente schématiquement
- figure 1 : vue en coupe d'une connexion,
- figure 2 : vue de dessus d'une plaque non encore équipée d'un organe de connexion.The invention will be better understood with the aid of the description below given by way of nonlimiting example, with reference to the attached drawing which schematically represents
- Figure 1: sectional view of a connection,
- Figure 2: top view of a plate not yet equipped with a connection member.
En se reportant au dessin, on voit que pour alimenter électriquement différents composants 1, l'appareil 2 comprend
- au moins deux plaques 3,4 conductrices notamment en cuivre disposées l'une au dessus de l'autre, dites inférieure 3 et supérieure 4 et isolées les unes des autres par une couche 5 d'un matériau isolant, lesdites plaques ayant des polarités différentes et
- rapportés sur ces plaques, des organes 6 de connexion sur chacun desquels se connecte électriquement un élément 7 de connexion ou borne du composant à alimenter.Referring to the drawing, it can be seen that in order to supply different components 1 electrically, the device 2 comprises
- At least two conductive plates 3,4 in particular made of copper placed one above the other, called lower 3 and upper 4 and isolated from each other by a layer 5 of an insulating material, said plates having polarities different and
- reported on these plates, connection members 6 on each of which electrically connects a connection element 7 or terminal of the component to be supplied.
Chaque organe 6 de connexion sur la plaque comprend
- un insert 8 tubulaire présentant à l'une de ses extrémités dite extrémité inférieure une couronne 9, lequel insert 8 est introduit dans une découpe 100 de la plaque jusqu'à ce que la couronne 9 soit en contact avec la plaque et
- une bague 10 engagée sur cet insert 8 après son introduction dans la découpe et venant en appui sur la face dite supérieure de la plaque et
- des moyens 11 d'immobilisation de l'insert et de la bague sur la plaque.Each connection member 6 on the plate comprises
a tubular insert 8 having at one of its ends said lower end a crown 9, which insert 8 is introduced into a cutout 100 of the plate until the crown 9 is in contact with the plate and
a ring 10 engaged on this insert 8 after its introduction into the cutout and coming to bear on the so-called upper face of the plate, and
- Means 11 for immobilizing the insert and the ring on the plate.
L'immobilisation de la bague se fait, par exemple, par sertissage ou collage. The immobilization of the ring is done, for example, by crimping or gluing.
L'élément de connexion du composant se présente généralement sous la forme d'une pièce métallique plane qui s'appuie sur l'insert 8 tubulaire et qui est maintenue appliquée et verrouillé sur l'organe de connexion au moyen d'une vis qui coopère avec un filetage réalisé, par exemple, dans l'alésage axial de la pièce tubulaire. The connection element of the component is generally in the form of a flat metallic piece which rests on the tubular insert 8 and which is kept applied and locked on the connection member by means of a cooperating screw. with a thread produced, for example, in the axial bore of the tubular part.
Les composants possèdent au moins deux éléments 7 de connexion en saillie sur l'une-de~~Ieurs~~faces~.- ~~ ~~
La plaque supérieure présente en outre, au droit des organes de connexion fixés sur les plaques inférieures, des larges découpes permettant l'accès aux organes de connexion des plaques inférieures.The components have at least two connection elements 7 projecting from one of ~~ them ~~ faces ~ .- ~~ ~~
The upper plate also has, in line with the connection members fixed to the lower plates, large cutouts allowing access to the connection members of the lower plates.
Selon une caractéristique de l'invention, la zone 14 dite d'appui de la plaque, sur laquelle est fixé l'organe 6 de connexion, se situe dans un plan P différent du plan T contenant la plaque et cette zone 14 dite d'appui est reliée à la plaque par une zone 15 dite de transition qui absorbe les contraintes dues aux variations de dimensions de la plaque et à la tolérance dimensionnelle des composants. According to a characteristic of the invention, the zone 14 known as the support of the plate, on which the connecting member 6 is fixed, is situated in a plane P different from the plane T containing the plate and this zone 14 known as the support is connected to the plate by a so-called transition zone 15 which absorbs the stresses due to variations in the dimensions of the plate and to the dimensional tolerance of the components.
La plaque présente ainsi sur une face des bossages obtenus, par exemple, par emboutissage de la plaque de cuivre. The plate thus has on one face bosses obtained, for example, by stamping the copper plate.
Avantageusement, la zone 14 d'appui et la zone 15 de transition présentent au moins trois fentes 16 sensiblement radiales s'étendant depuis le bord de la découpe logeant l'insert et angulairement régulièrement réparties. Advantageously, the support zone 14 and the transition zone 15 have at least three substantially radial slots 16 extending from the edge of the cutout housing the insert and angularly regularly distributed.
Les fentes 16 seront, avantageusement, au nombre de six. The slots 16 will advantageously be six in number.
Ces fentes confèrent de la souplesse au bossage et autorisent une inclinaison de l'axe 17 de l'insert 8 sans risquer la désolidarisation de l'organe de connexion. These slots give flexibility to the boss and allow an inclination of the axis 17 of the insert 8 without risking the separation of the connection member.
Le nombre de fentes et leur largeur dépend de l'épaisseur de la plaque, mais elles doivent préserver un contact suffisant et notamment obtenir un rapport par intensité de courant par unité de surface inférieure à 2A/mm2. The number of slots and their width depends on the thickness of the plate, but they must maintain sufficient contact and in particular obtain a ratio by current intensity per unit area less than 2A / mm2.
Les fentes 16 se prolongent au delà de la zone de transition. The slots 16 extend beyond the transition zone.
