Definitions
- an insulated metal substrate 1 (or SMI) is conventionally constituted by a metal plate la on which is deposited an insulating layer 1b which itself carries a conductive layer 1c (copper for example) which is formed of conductive tracks.
- the insulating layer 1b and the layer or the conductive tracks 1c form a printed circuit which is integral with the metal plate la.
- the latter allows the evacuation of the calories generated by the printed circuit.
- the insulating layer 1b will be made of a material promoting thermal transfer.
- the metal plate 1a can be made of aluminum or copper.
- the insulated metal substrate comprises at least one rod 2 which is fixed to the metal plate 1a of the insulated metal substrate 1.
- Each stud 2 has a head 2a which is crimped into the metal plate la. The number of rods will be chosen according to the current density flowing in them.
- the diameter of the rods will also depend on the mechanical strength desired for the connection.
- On the rod (s) 2 is fixed at least one contact terminal 3 which is intended to bring a supply current to the circuit carried by the insulated metal substrate 1.
- the terminal 3 is in electrical contact with the conductive track 1c carried by the substrate 1.
- the conductive track 1c is not in contact with the rod 2 because an annular insulating savings area 4 has been arranged at this level.
- This zone will have a width sufficient to avoid any dielectric breakdown between the terminal 3 and the rod 2.
- a width of the order of 1 to 2 mm is generally sufficient for supply voltages of the order of 500 volts.
- connection device comprises an insulating barrel 5, having a tubular part 5a which is positioned in a hole 3a of the terminal 3, and a flange 5b which is kept applied against the terminal 3 by a clamping means 6, integral with the rod 2.
- the clamping means 6 here comprises a nut 7, which is screwed onto the rod 2, and which pushes a set of washers 8a, 8b and 8c against the insulating barrel 5.
- the lower washer 8c is supported on the collar 5b of the barrel insulator 5.
- a printed circuit 9 is interposed between the central washer 8b and the lower washer 8c.
- the upper washer Sa is an elastic lock washer which prevents loosening of the nut 7 and compensates for thermal expansion.
- the elastic lock washer is only crushed approximately 50% of its maximum crushing so that thermal expansion can be compensated.
- the barrel 5 provides electrical insulation of the terminal 3 and of the rod 2.
- the tubular part 5a of the barrel is interposed radially between the terminal 3 and the rod 2 and the flange 5b is interposed between the washer 8c and the terminal 3.
- the thicknesses of the barrel 5, both at the tubular part 5a and at the flange 5b, are chosen so as to ensure good insulation.
- the hole 3a of the terminal 3 has a flare 3b which receives an annular seal 10.
- the flare 3b is here conical and the annular seal 10 is an O-ring.
- This seal 10 is made of an insulating material, for example of the silicone type. The seal 10 is therefore interposed between the rod 2 and the terminal 3, below the tubular part 5a of the insulating barrel 5.
- the joint completes the electrical insulation between the rod 2 and the terminal 3. In fact, it makes it possible to partially fill the cavity separating the rod 2 and the terminal 3, which reduces the risks of electric discharge in the air.
- the contact resistance between the terminal 3 and the conductive track 1c remains reduced by around 20 micro ohms for the whole temperature range (from -50 ° C to + 100 ° C). This contact resistance is ensured over the entire temperature range thanks to the presence of the elastic washer 8a which makes it possible to compensate for the expansions.
- the device according to the invention makes it possible to easily make a connection with low contact resistance, thanks to the positive tightening ensured by the nut 7 and the washers 8a, 8b, 8c.
- the tightening combines with electrical insulation, thanks to the barrel 5 on the one hand, and the O-ring 10 on the other hand. It is necessary to leave an axial clearance between the barrel 5 and the insulated metal substrate 1 to allow clamping, therefore good electrical contact. This play would be a source of risk of dielectric breakdown.
- the presence of the O-ring 10 eliminates this risk.
- the deformability of the seal 10 allows it to be compressed by the barrel 5 during tightening, which increases the insulation by reducing the presence of air between the terminal 3 and the rod 2.

Description
Le domaine technique de l'invention est celui des dispositifs de connexion électrique pour un circuit imprimé et en particulier pour un circuit de type substrat métallique isolé.
Les substrats métalliques isolés (ou SMI) sont de plus en plus utilisés aujourd'hui, en particulier pour les circuits électroniques de puissance et pour les circuits utilisés dans les éclairages à base de diodes émettrices de lumière (LED).
Les substrats métalliques isolés comprennent une plaque métallique (ou semelle), le plus souvent en aluminium, sur laquelle est déposée une couche isolante qui porte un circuit imprimé.
La plaque métallique permet d'évacuer les calories engendrées par le circuit imprimé.
Il est nécessaire de réaliser des connexions électriques fiables sur le substrat métallique isolé, c'est-à-dire sur le circuit imprimé porté par le substrat métallique isolé.
Ces connexions électriques doivent tout à la fois être peu coûteuses à réaliser et à assembler, et également assurer un contact électrique de faible impédance (quelques dizaines de micro ohms), contact qui doit rester constant dans le temps. Le courant passant par la connexion peut par ailleurs atteindre des valeurs importantes (quelques centaines d'ampères, voire jusqu'à 1000 ampères).
Il est connu du brevet
Cette connexion est spécifique à la réalisation d'une liaison entre deux circuits imprimés fixés à distance l'un de l'autre. Elle ne permet pas de réaliser une liaison électrique avec une cosse de contact reliant le substrat métallique isolé à l'extérieur. En particulier, si aucun contact électrique ne doit se faire simultanément entre la cosse et les deux circuits, le niveau d'isolation électrique entre la cosse et les circuits isolés devient insuffisant.
La connexion décrite par le brevet
C'est le but de l'invention que de proposer un dispositif de connexion permettant de relier facilement à un conducteur de puissance un circuit d'un substrat métallique isolé, tout en assurant un niveau d'isolation important entre la cosse et la tige qui permet la fixation mécanique de la cosse sur le circuit.
Ainsi l'invention a pour objet un dispositif de connexion électrique pour substrat métallique isolé, dispositif comprenant un substrat, une cosse de contact, et au moins une tige fixée à une plaque métallique du substrat et sur laquelle vient se fixer la cosse de contact qui est en contact électrique avec une piste conductrice portée par le substrat, dispositif caractérisé en ce qu'il comprend en outre un moyen de serrage et un joint annulaire en matériau isolant, la cosse comportant un trou permettant le passage de la tige et le dispositif comportant un canon isolant qui présente une partie tubulaire se positionnant dans le trou et une collerette qui est maintenue appliquée contre la cosse par le moyen de serrage solidaire de la tige, le canon assurant ainsi l'isolation électrique de la cosse et de la tige, le trou de la cosse comportant un évasement recevant le joint annulaire qui s'interpose entre la tige et la cosse.
Selon un mode particulier de réalisation, le joint annulaire pourra être un joint torique.
L'évasement de la cosse pourra avoir un profil conique.
Selon un mode particulier de réalisation, la tige pourra être un goujon fileté ayant une tête sertie dans la masse métallique du substrat.
Avantageusement, le moyen de serrage pourra comprendre au moins une rondelle frein élastique.
Avantageusement la rondelle frein élastique ne sera pas serrée à son écrasement maximal pour permettre de compenser les dilatations thermiques.
L'invention sera mieux comprise à la lecture de la description qui va suivre d'un mode particulier de réalisation, description faite en référence aux dessins annexés et dans lesquels :
- La
figure 1 est une vue en coupe d'une partie d'un substrat métallique isolé comportant un dispositif de connexion selon l'invention; - La
figure 2 est une vue partielle, en perspective et en coupe de ce substrat métallique isolé portant le dispositif de connexion selon l'invention.
Insulated metallic substrates (or SMI) are increasingly used today, in particular for electronic power circuits and for circuits used in lighting based on light emitting diodes (LEDs).
Insulated metal substrates include a metal plate (or sole), most often made of aluminum, on which is deposited an insulating layer which carries a printed circuit.
The metal plate allows the calories generated by the printed circuit to be removed.
It is necessary to make reliable electrical connections on the insulated metal substrate, that is to say on the printed circuit carried by the insulated metal substrate.
These electrical connections must both be inexpensive to make and assemble, and also provide an electrical contact of low impedance (a few tens of micro ohms), contact which must remain constant over time. The current passing through the connection can also reach significant values (a few hundred amperes, or even up to 1000 amps).
It is known from the patent
This connection is specific to the creation of a connection between two printed circuits fixed at a distance from each other. It does not allow an electrical connection to be made with a contact lug connecting the metal substrate insulated to the outside. In particular, if no electrical contact is to be made simultaneously between the terminal and the two circuits, the level of electrical insulation between the terminal and the isolated circuits becomes insufficient.
The connection described by the patent
It is the object of the invention to provide a connection device making it possible to easily connect a circuit of an insulated metal substrate to a power conductor, while ensuring a high level of insulation between the terminal and the rod which allows mechanical fixing of the terminal on the circuit.
Thus, the subject of the invention is an electrical connection device for an insulated metal substrate, device comprising a substrate, a contact lug, and at least one rod fixed to a metal plate of the substrate and on which the contact lug which is fixed is in electrical contact with a conductive track carried by the substrate, device characterized in that it further comprises a clamping means and an annular seal made of insulating material, the terminal comprising a hole allowing the passage of the rod and the device comprising an insulating barrel which has a tubular part which is positioned in the hole and a collar which is kept applied against the lug by the clamping means integral with the rod, the barrel thus ensuring the electrical insulation of the lug and the rod, the hole of the lug comprising a flare receiving the annular seal which is interposed between the rod and the lug.
According to a particular embodiment, the annular seal may be an O-ring.
The flare of the terminal may have a conical profile.
According to a particular embodiment, the rod may be a threaded stud having a head crimped into the metallic mass of the substrate.
Advantageously, the clamping means may comprise at least one elastic locking washer.
Advantageously, the elastic locking washer will not be tightened to its maximum crushing in order to compensate for thermal expansion.
The invention will be better understood on reading the description which follows of a particular embodiment, description made with reference to the appended drawings and in which:
- The
figure 1 is a sectional view of part of an insulated metal substrate comprising a connection device according to the invention; - The
figure 2 is a partial perspective view in section of this insulated metal substrate carrying the connection device according to the invention.
En se reportant aux figures, un substrat métallique isolé 1 (ou SMI) est constitué de façon classique par une plaque métallique la sur laquelle est déposée une couche isolante 1b qui porte elle-même une couche conductrice 1c (en cuivre par exemple) qui est formée de pistes conductrices.Referring to the figures, an insulated metal substrate 1 (or SMI) is conventionally constituted by a metal plate la on which is deposited an
La couche isolante 1b et la couche ou les pistes conductrices 1c forment un circuit imprimé qui est solidaire de la plaque métallique la. Cette dernière permet l'évacuation des calories générées par le circuit imprimé. La couche isolante 1b sera réalisée en un matériau favorisant le transfert thermique.
La plaque métallique la peut être réalisée en aluminium ou en cuivre.
Comme on le voit sur les figures, le substrat métallique isolé comprend au moins une tige 2 qui est fixée à la plaque métallique la du substrat métallique isolé 1.
Il y a ici trois tiges 2 parallèles (visibles à la
Sur la ou les tiges 2 vient se fixer au moins une cosse de contact 3 qui est destinée à amener un courant d'alimentation au circuit porté par le substrat métallique isolé 1.
La cosse 3 est en contact électrique avec la piste conductrice 1c portée par le substrat 1. Comme on le voit sur la
Par ailleurs le dispositif de connexion comporte un canon isolant 5, présentant une partie tubulaire 5a qui se positionne dans un trou 3a de la cosse 3, et une collerette 5b qui est maintenue appliquée contre la cosse 3 par un moyen de serrage 6, solidaire de la tige 2.
Le moyen de serrage 6 comprend ici un écrou 7, qui se visse sur la tige 2, et qui pousse un jeu de rondelles 8a, 8b et 8c contre le canon isolant 5. La rondelle inférieure 8c est en appui sur la collerette 5b du canon isolant 5. Un circuit imprimé 9 est interposé entre la rondelle médiane 8b et la rondelle inférieure 8c. Ainsi la tige 2 du dispositif de connexion assure également un maintien mécanique de ce circuit 9 à distance du substrat métallique isolé 1 et parallèlement à ce dernier.
La rondelle supérieure Sa est une rondelle frein élastique qui empêche le desserrage de l'écrou 7 et compense les dilatations thermiques. La rondelle frein élastique n'est écrasée qu'à 50% environ de son écrasement maximal pour que les dilatations thermiques puissent être compensées.
Le canon 5 assure l'isolation électrique de la cosse 3 et de la tige 2. En effet la partie tubulaire 5a du canon s'interpose radialement entre la cosse 3 et la tige 2 et la collerette 5b s'interpose entre la rondelle 8c et la cosse 3.
Les épaisseurs du canon 5, tant au niveau de la partie tubulaire 5a que de la collerette 5b, sont choisies de façon à assurer une bonne isolation.
Comme on le voit sur les figures, le trou 3a de la cosse 3 comporte un évasement 3b qui reçoit un joint annulaire 10. L'évasement 3b est ici conique et le joint annulaire 10 est un joint torique. Ce joint 10 est réalisé en un matériau isolant par exemple de type silicone.
Le joint 10 s'interpose donc entre la tige 2 et la cosse 3, en dessous de la partie tubulaire 5a du canon isolant 5.The

As can be seen in the figures, the insulated metal substrate comprises at least one

Le joint complète l'isolement électrique entre la tige 2 et la cosse 3. En effet, il permet de combler en partie la cavité séparant la tige 2 et la cosse 3, ce qui réduit les risques de décharge électrique dans l'air.
On a pu mesurer que la tension d'isolement se trouvait fortement augmentée grâce à la seule présence du joint 10. On passe ainsi, avec la configuration représentée sur les figures, d'une tension d'isolement de 500 volts sans joint à une tension d'isolement supérieure à 1500 volts continus avec le joint.
La résistance de contact entre la cosse 3 et la piste conductrice 1c reste réduite de l'ordre de 20 micro ohms pour toute la gamme de températures (de -50°C à +100°C). Cette résistance de contact est assurée sur toute la plage de températures grâce à la présence de la rondelle élastique 8a qui permet de compenser les dilatations.
Ainsi le dispositif selon l'invention permet de réaliser facilement une connexion à faible résistance de contact, grâce au serrage positif assuré par l'écrou 7 et les rondelles 8a,8b,8c.
Le serrage se combine à l'isolation électrique, grâce au canon 5 d'une part, et au joint torique 10 d'autre part.
Il est nécessaire de laisser un jeu axial entre le canon 5 et le substrat métallique isolé 1 pour permettre le serrage, donc le bon contact électrique. Ce jeu serait source de risque de claquage diélectrique. La présence du joint torique 10 permet de faire disparaître ce risque. Par ailleurs la déformabilité du joint 10 permet sa compression par le canon 5 lors du serrage, ce qui augmente l'isolation en réduisant la présence d'air entre la cosse 3 et la tige 2.The joint completes the electrical insulation between the

On a décrit un mode de réalisation dans lequel le joint était torique (section circulaire) et logé dans un évasement à profil conique.
Il serait possible de mettre en oeuvre un joint annulaire à section différente (carrée ou prismatique) qui se logerait dans un évasement de forme différente, par exemple un lamage cylindrique.
Dans tous les cas, le joint permettra de réduire la présence d'air dans l'évasement, donc améliorera l'isolation. La compression du joint par le canon pourra également intervenir et déformer le joint.
On a également décrit une ou plusieurs tiges 2 réalisées sous la forme de goujons filetés sertis dans le substrat métallique isolé 1.
Les tiges pourraient alternativement être des tiges filetées fixées par un écrou de chaque côté du substrat métallique isolé. On pourra aussi utiliser des tiges lisses, mais portant à leur extrémité un dispositif de serrage, par exemple une grenouillère.An embodiment has been described in which the seal was O-ring (circular section) and housed in a flare with a conical profile.
It would be possible to use an annular seal with a different section (square or prismatic) which would be housed in a flare of different shape, for example a cylindrical counterbore.
In all cases, the joint will reduce the presence of air in the flare, thus improving the insulation. The compression of the joint by the barrel can also intervene and deform the joint.

The rods could alternatively be threaded rods fixed by a nut on each side of the insulated metal substrate. One can also use smooth rods, but carrying at their end a clamping device, for example a sleepsuit.
