Description

La présente invention se rapporte à un connecteur électrique et thermique susceptible d'établir des contacts électriques avec des conducteurs imprimés ou gravés d'une carte ainsi que des contacts thermiques avec une âme ou une face en métal ou en céramique d'une telle carte.The present invention relates to an electrical and thermal connector capable of establishing electrical contacts with printed or engraved conductors of a card as well as thermal contacts with a core or a metal or ceramic face of such a card.

Elle se rapporte également à des fiches de connexion électrique pouvant relier une telle carte avec ce type de connecteur.It also relates to electrical connection plugs which can connect such a card with this type of connector.

Il existe des cartes à conducteurs imprimés ou gravés dont le support est réalisé en un matériau bon conducteur de la chaleur comme par exemple une tôle d'acier ou une tôle d'aluminium. Une couche d'émail isolante recouvre en général les deux faces de la tôle, et des conducteurs électriques y sont imprimés ou gravés par une technique appropriée de façon à constituer un ou plusieurs réseaux d'interconnexion pour un ou plusieurs circuits électriques. Ce support métallique est le conducteur thermique de la carte qui contribue efficacement au refroidissement du ou des circuits électriques.There are cards with printed or engraved conductors, the support of which is made of a material which is a good conductor of heat, for example a sheet of steel or a sheet of aluminum. An insulating enamel layer generally covers the two faces of the sheet, and electrical conductors are printed or engraved thereon by an appropriate technique so as to constitute one or more interconnection networks for one or more electrical circuits. This metal support is the thermal conductor of the card which effectively contributes to the cooling of the electrical circuit (s).

Les connecteurs électriques classiques qui établissent des contacts électriques avec les conducteurs électriques d'une telle carte ne contribuent guère à évacuer de la chaleur car leur corps est pour des motifs d'isolement réalisé en un matériau plastique peu ou pas chargé. Un tel matériau est considéré généralement comme un mauvais conducteur de la chaleur.Conventional electrical connectors which establish electrical contacts with the electrical conductors of such a card do little to dissipate heat because their body is, for reasons of isolation, made of a lightly or not charged plastic material. Such a material is generally considered to be a poor conductor of heat.

Les connecteurs électriques classiques à corps plastique qui sont connectés aux conducteurs d'une tôle émaillée n'établissent des connexions thermiques que par leurs conducteurs électriques. La capacité de transférer de la chaleur par conduction thermique de ces conducteurs est limitée à cause de leur structure fine et allongée et de leurs faibles surfaces de contact.Conventional electrical connectors with plastic bodies which are connected to the conductors of an enamelled sheet establish thermal connections only through their electrical conductors. The capacity to transfer heat by thermal conduction of these conductors is limited because of their fine and elongated structure and their small contact surfaces.

D'autres moyens de conduction thermique doivent être recherchés si l'on veut obtenir un meilleur refroidissement de la carte et par conséquent du circuit électrique porté par la carte.Other means of thermal conduction must be sought if one wishes to obtain better cooling of the card and consequently of the electrical circuit carried by the card.

Le problème consistant à établir des connexions thermiques au moyen de connecteurs électriques est également soulevé dans les cas d'utilisation de différentes cartes ou plaques isolées servant de support à un ou plusieurs circuits électriques et dont les types sont les suivants :

  • carte imprimée comportant un collecteur thermique en couche interne ;
  • carte imprimée comportant un drain thermique fixé sur une face de la carte ;
  • tôle métallique recouverte sur l'une ou sur les deux faces par un film plastique mince ;.
  • tôle d'aluminium anodisée sur l'une ou sur les deux faces.
The problem of establishing thermal connections by means of electrical connectors is also raised in the case of the use of different insulated cards or plates serving as support for one or more electrical circuits, the types of which are as follows:
  • printed board comprising an internal layer thermal collector;
  • printed card comprising a heat sink fixed on one face of the card;
  • metal sheet covered on one or both sides with a thin plastic film;
  • anodized aluminum sheet on one or both sides.

Le problème de connexion thermique est posé notamment dans des appareils ou équipements électriques comportant un grand nombre de cartes de circuits électriques que l'on désire soit interconnecter à la fois électriquement et thermiquement, soit connecter électriquement entre eux et thermiquement avec une masse métallique à l'intérieur d'un bâti dans le but d'obtenir un meilleur refroidissement des circuits électriques.The problem of thermal connection is posed in particular in electrical apparatus or equipment comprising a large number of electrical circuit boards which it is desired either to interconnect both electrically and thermally, or to connect electrically between them and thermally with a metallic mass to the interior of a frame in order to obtain better cooling of electrical circuits.

Pour pouvoir réaliser de véritables interconnexions à la fois électriques et thermiques, il faut disposer d'un connecteur électrique à conduction thermique élevée.In order to be able to make real electrical and thermal interconnections, an electrical connector with high thermal conduction is required.

Une solution à ce problème est exposée dans le brevet U-A-4 162 818. Elle consiste à utiliser des ressorts isolés électriquement, sauf dans leur zone de contact avec le circuit imprimé. Au dos de la carte imprimée, est fixée une plaque permettant de dissiper les calories engendrées par les circuits. Cependant, la forme du contact thermique entre la paroi du connecteur et la plaque formant radiateur est telle que la résistance thermique de ce contact est assez élevée (faible surface de contact).A solution to this problem is set out in patent U-A-4,162,818. It consists in using electrically isolated springs, except in their area of contact with the printed circuit. On the back of the printed card, a plate is attached to dissipate the calories generated by the circuits. However, the shape of the thermal contact between the wall of the connector and the radiator plate is such that the thermal resistance of this contact is quite high (small contact surface).

La présente invention a pour objet un connecteur électrique et thermique pour cartes comprenant un couloir d'insertion de carte comportant au moins un conducteur de connexion électrique ayant au moins une extrémité de contact flexible, des moyens pour appliquer les extrémités de contacts flexibles sur les moyens de conduction électrique de la carte, et des moyens de conduction d'énergie thermique isolés électriquement des moyens de conduction électrique de la carte et destinés à établir par contact mutuel avec une face d'une telle carte une connexion thermique, lesdits moyens de conduction d'énergie thermique étant constitués par une aile métallique longitudinale comportant une paroi avec une face de guidage et d'appui de la carte, caractérisé en ce que l'aile métallique longitudinale est disposée en équerre, sa paroi avec sa face de guidage et d'appui de la carte, étant séparée, par le couloir d'insertion, d'une paroi d'aile longitudinale en matériau isolant qui lui est parallèle, et en ce que le conducteur de connexion électrique a la forme d'une bande cintrée comportant plusieurs languettes de contact séparées par des créneaux, ainsi que plusieurs languettes de fixation repliées vers l'extérieur des créneaux et qui sont ancrées dans la paroi de l'aile isolante.The present invention relates to an electrical and thermal connector for cards comprising a card insertion corridor comprising at least one electrical connection conductor having at least one flexible contact end, means for applying the flexible contact ends to the means for electrical conduction of the card, and thermal energy conduction means electrically isolated from the electrical conduction means of the card and intended to establish, by mutual contact with one face of such a card, a thermal connection, said conduction means d thermal energy being constituted by a longitudinal metal wing comprising a wall with a guide and support face of the card, characterized in that the longitudinal metal wing is arranged at right angles, its wall with its guide and support of the card, being separated, by the insertion corridor, from a longitudinal wing wall of insulating material which is parallel to it, and in that the electrical connection conductor has the form of a curved strip comprising several contact tabs separated by slots, as well as several fixing tabs folded outwards from the slots and which are anchored in the wall of the wing insulating.

La présente invention concerne également une fiche de connexion enfichable dans le connecteur précédent et destinée à être montée sur un bord d'une telle carte, cette fiche comprenant des conducteurs électriques sous la forme de lamelles métalliques et un conducteur d'énergie thermique qui est isolé par rapport aux conducteurs électriques que porte la fiche et qui est réalisé en un matériau de conductibilité thermique élevée.The present invention also relates to a connection plug which can be plugged into the previous connector and is intended to be mounted on an edge of such a card, this plug comprising electrical conductors in the form of metal strips and a thermal energy conductor which is isolated. compared to the electrical conductors carried by the plug and which is made of a material with high thermal conductivity.

Les objets et caractéristiques de la présente invention apparaîtront plus clairement à la lecture de la description suivante d'exemples de réalisation, ladite description étant faite en relation avec les dessins ci-annexés dans lesquels :

  • les figures 1 et 2 représentent schématiquement par une vue en coupe d'une forme de réalisation préférée d'un connecteur selon l'invention respectivement avant et après insertion d'une carte ;
  • la figure 3 représente un type de conducteurs de connexion électrique pouvant équiper le connecteur selon l'invention ;

  • la figure 5 représente schématiquement un système d'interconnexion électrique et thermique réalisé avec un connecteur selon l'invention ;
  • la figure 6 représente schématiquement une vue en coupe d'une forme préférée de fiche de connexion pour une carte à relier aux connecteurs ci-dessus.
The objects and characteristics of the present invention will appear more clearly on reading the following description of exemplary embodiments, said description being made in relation to the attached drawings in which:
  • Figures 1 and 2 schematically represent a sectional view of a form of preferred embodiment of a connector according to the invention respectively before and after insertion of a card;
  • FIG. 3 represents a type of electrical connection conductors which can be fitted to the connector according to the invention;

  • FIG. 5 schematically represents an electrical and thermal interconnection system produced with a connector according to the invention;
  • FIG. 6 schematically represents a sectional view of a preferred form of connection plug for a card to be connected to the above connectors.

Les fiches 1 et 2 montrent respectivement une coupe d'une forme de réalisation du connecteur selon l'invention avant et après insertion d'une carte 103. Dans celle-ci, des conducteurs flexibles 101 sont appliqués fortement par une came 100 sur la face 104 conductrice de la carte 103 engagée dans le connecteur et dont le drain thermique 105 a été mis au contact du conducteur thermique 106 du connecteur.Sheets 1 and 2 respectively show a section of an embodiment of the connector according to the invention before and after insertion of a card 103. In it, flexible conductors 101 are applied strongly by a cam 100 on the face 104 conductor of the card 103 engaged in the connector and whose heat sink 105 has been brought into contact with the thermal conductor 106 of the connector.

Ils assurent également des liaisons électriques entre ceux 104 portés par la carte 103 et ceux 108 portés par une couche isolante 109 déposée sur un puit thermique 110 sur lequel est monté, le conducteur thermique 106 du connecteur. Ce puit thermique peut être une plaque métallique éventuellement refroidie par un fluide froid.They also provide electrical connections between those 104 carried by the card 103 and those 108 carried by an insulating layer 109 deposited on a thermal well 110 on which is mounted, the thermal conductor 106 of the connector. This thermal well may be a metal plate possibly cooled by a cold fluid.

Sur la figure 3, les conducteurs 101 sont formés dans une bande 112 métallique flexible légèrement cintrée dans le sens transversal, et qui a été découpée pour obtenir des languettes de fixation 113 qui sont ensuite pliées à peu près à angle droit vers le côté concave de la bande. Des languettes de contact 114 qui subsistent après découpe, entre des créneaux 115 forment alors les extrémités des conducteurs du connecteur qui sont reliées par exemple par soudure 111 avec les conducteurs 108 pour établir un contact de masse ou une alimentation électrique de la carte. Les languettes de fixation 113 sont rendues solidaires de l'aile 116 moulée en matériau isolant, par exemple par surmoulage avec du matériau plastique utilisé pour le moulage de l'aile 116.In FIG. 3, the conductors 101 are formed in a flexible metal strip 112 slightly bent in the transverse direction, and which has been cut to obtain fixing tabs 113 which are then bent at approximately right angles towards the concave side of the band. Contact tabs 114 which remain after cutting, between slots 115 then form the ends of the conductors of the connector which are connected for example by welding 111 with the conductors 108 to establish a ground contact or an electrical supply to the card. The fixing tabs 113 are made integral with the wing 116 molded in insulating material, for example by overmolding with plastic material used for molding the wing 116.

La figure 4 représente une variante du connecteur comprenant des conducteurs de connexion flexibles comportant deux languettes de fixation 120 et 121 ancrées toutes les deux dans un corps 124 de connecteur réalisé complètement en un matériau très bon conducteur de chaleur, par exemple métallique. Les deux languettes 120 et 121 sont isolées électriquement soit par gainage, soit par enrobage de matière plastique.FIG. 4 represents a variant of the connector comprising flexible connection conductors comprising two fixing tabs 120 and 121 both anchored in a connector body 124 made completely of a material which is a very good conductor of heat, for example metallic. The two tongues 120 and 121 are electrically insulated either by sheathing or by coating with plastic material.

Comme dans les cas précédents, les extrémités de contact supérieures des conducteurs 119 peuvent être appliquées par exemple par une came 122 en matière isolante, contre les conducteurs imprimés sur une face de carte à drain ou paroi thermique insérée dans le connecteur.As in the previous cases, the upper contact ends of the conductors 119 can be applied for example by a cam 122 made of insulating material, against the conductors printed on a face of the drain card or thermal wall inserted in the connector.

La bande 119 à contacts 121 peut être reliée à une masse ou un appareil électrique en établissant une liaison électrique par des moyens de connexion électrique tels que des fils soudés, fils rivés, prises de courant branchées à une extrémité longitudinale du conducteur 119.The strip 119 with contacts 121 can be connected to an earth or an electrical appliance by establishing an electrical connection by electrical connection means such as soldered wires, riveted wires, sockets connected to a longitudinal end of the conductor 119.

Une autre application possible d'une bande 119, à contacts 121, similaire à la bande 112, est la vérification de l'établissement du contact thermique entre la carte et la paroi thermique du connecteur. Dans ce cas, on peut utiliser une bande 119 comportant par exemple deux contacts 121 et les appliquer par la came 122 sur deux plots portés par la carte de manière à fermer un circuit électrique de contrôle.Another possible application of a strip 119, with contacts 121, similar to the strip 112, is the verification of the establishment of thermal contact between the card and the thermal wall of the connector. In this case, it is possible to use a strip 119 comprising for example two contacts 121 and to apply them by the cam 122 to two pads carried by the card so as to close an electrical control circuit.

L'invention s'applique aisément à tous les connecteurs pour cartes de circuit imprimé du genre mentionné précédemment, comportant notamment une surface de paroi ou une âme métallique, même si celles-ci sont protégées ou enrobées d'un film plastique ou revêtues d'une couche d'oxyde métallique électriquement isolante.The invention is easily applicable to all connectors for printed circuit boards of the kind mentioned above, comprising in particular a wall surface or a metallic core, even if these are protected or coated with a plastic film or coated with an electrically insulating metal oxide layer.

La figure 5 représente à titre d'exemple un système d'interconnexion électrique et thermique dans lequel une carte « fille 80 de surface rectangulaire, à face 81 métallique, est montée d'une part par ses bords longitudinaux dans des guide-cartes 82 et d'autre part, est fixée par un bord latéral à une fiche 83 d'un genre décrit ci-dessus. Cette fiche 83 est engagée dans un connecteur 84 mixte dont une paroi de base est appliquée sur une carte maîtresse 85 d'un type analogue à celles mentionnées précédemment. Cette carte maîtresse 85 peut porter un circuit électrique sur cette même face isolée par un émail ou sur l'autre face. Les conducteurs 86 de connexion électrique du connecteur 84 traversent alors des trous dans la carte maîtresse 85 qui sont revêtus d'une couche isolante et ils sont réunis au circuit électrique directement ou par l'intermédiaire des conducteurs imprimés ou gravés sur la carte.FIG. 5 shows by way of example an electrical and thermal interconnection system in which a daughter card 80 of rectangular surface, with metal face 81, is mounted on the one hand by its longitudinal edges in card guides 82 and on the other hand, is fixed by a side edge to a plug 83 of a kind described above. This plug 83 is engaged in a mixed connector 84, a base wall of which is applied to a master card 85 of a type similar to those mentioned above. This master card 85 can carry an electrical circuit on this same face isolated by an enamel or on the other face. The electrical connection conductors 86 of the connector 84 then pass through holes in the master card 85 which are coated with an insulating layer and they are connected to the electrical circuit directly or through the conductors printed or engraved on the card.

Un ou plusieurs éléments métalliques tels que des pièces d'un châssis 87, 88 peuvent en outre être connectés, comme cela est représenté, à la carte maîtresse 85.One or more metallic elements such as parts of a chassis 87, 88 can also be connected, as shown, to the master card 85.

Il est préférable d'employer du métal comme matériau constituant la paroi thermique du connecteur ou de la fiche assortie au connecteur. Toutefois, une paroi en un autre matériau de bonne conduction thermique tel que la céramique par exemple pourrait être également employée.It is preferable to use metal as the material constituting the thermal wall of the connector or of the plug matching the connector. However, a wall made of another material with good thermal conduction such as ceramic for example could also be used.

La figure 6 montre que le connecteur selon l'invention est également applicable à des cartes de type enfichable lorsque celles-ci sont munies d'une fiche de connexion 40 assortie au connecteur mixte précédent.FIG. 6 shows that the connector according to the invention is also applicable to cards of the plug-in type when these are provided with a connection plug 40 which matches the preceding mixed connector.

La fiche 40 de connexion est alors fixée de la manière représentée, au bord d'une carte 41 à paroi 4la métallique. Une paroi 42 isolante de la fiche 40 est appliquée sur le bord de la face portant les conducteurs 43 de la carte 41.The connection plug 40 is then fixed in the manner shown, to the edge of a card 41 with a metal wall 4la. An insulating wall 42 of the plug 40 is applied to the edge of the face carrying the conductors 43 of the card 41.

. Dans des logements (non figurés) sont maintenus des conducteurs 44 de connexion électrique de la fiche 40 réalisés sous forme de tronçons de fils ou de lamelles à flexibilité contrôlée de genre connu. Des extrémités 44a de ceux-ci sont en contacts, par exemple par soudage, avec les conducteurs 43 imprimés ou gravés de la carte 41. Des extrémités 44b opposées sont dirigées le long d'une face externe de là paroi 42 isolante et ancrées à celle-ci. Ainsi, ils pourront prendre contact respectivement avec les conducteurs 47 d'un connecteur 46 à paroi 48 thermique métallique du type décrit précédemment.. In housings (not shown) are maintained conductors 44 for electrical connection of the plug 40 produced in the form of sections of wires or lamellae with controlled flexibility of known type. The ends 44a of these are in contact, for example by welding, with the conductors 43 printed or engraved on the card 41. Opposite ends 44b are directed along an external face of the insulating wall 42 and anchored to that -this. Thus, they can contact respectively the conductors 47 of a connector 46 with a metallic thermal wall 48 of the type described above.

La fiche 40 présente en outre une paroi 45 métallique destinée à être appliquée contre la face interne de la paroi 48 thermique du connecteur 46 lors de son insertion. La paroi 45 peut être munie de parties 45a saillantes qui sont noyées par surmoulage dans la paroi 42 isolante. Elle est fixée au dos de la paroi 4la métallique de la carte 41 par des moyens convenables tels que vis, rivets ou colle.The plug 40 also has a metal wall 45 intended to be applied against the internal face of the thermal wall 48 of the connector 46 during its insertion. The wall 45 may be provided with projecting parts 45a which are embedded by overmolding in the insulating wall 42. It is fixed to the back of the metal wall 4 of the card 41 by suitable means such as screws, rivets or glue.

Après insertion de la fiche 40 dans le connecteur 46, un contact mutuel est établi entre la paroi 45 de la fiche et la paroi 48 du connecteur 46.After inserting the plug 40 into the connector 46, mutual contact is established between the wall 45 of the plug and the wall 48 of the connector 46.

La chaleur provenant d'un circuit en fonctionnement monté sur les conducteurs 43 de la carte 41 sera ainsi transmise par la paroi 41a métallique à fa paroi 45 métallique de la fiche 40, puis à la paroi 48 thermique du connecteur 46.The heat coming from an operating circuit mounted on the conductors 43 of the card 41 will thus be transmitted by the metal wall 41a to the metal wall 45 of the plug 40, then to the thermal wall 48 of the connector 46.

Par leurs caractères à la fois électrique et thermique, les connecteurs et les fiches de connexion décrits ci-dessus sont capables de transporter simultanément de l'énergie électrique et de l'énergie thermique et d'être utilisés dans un système d'interconnexion électrique et thermique.Due to their electrical and thermal characteristics, the connectors and plugs described above are capable of simultaneously transporting electrical energy and thermal energy and of being used in an electrical interconnection system and thermal.
