Description

L'invention est relative à une barrette de raccordement électrique de carte de circuit imprimé constituée d'un support et d'une rangée de blocs de jonction, les blocs étant montés côte à côte sur ledit support et étant prévus pour recevoir par leurs faces supérieures des contacts faisant saillie à partir d'un bord d'une carte à circuits imprimés, et ayant des bornes de raccordement extérieur sur au moins une face latérale, qui est parallèle à l'axe de la barrette.The invention relates to an electrical connection strip of a printed circuit board consisting of a support and a row of terminal blocks, the blocks being mounted side by side on said support and being provided for receiving by their upper faces. contacts projecting from an edge of a printed circuit board, and having external connection terminals on at least one lateral face, which is parallel to the axis of the strip.

Un bloc de jonction comporte ainsi normalement des bornes reliées à un circuit d'entrée, des bornes reliées à un circuit de sortie et des bornes de raccordement à une carte de circuit imprimé. Or il est intéressant, lorsqu'on réalise une installation, de pouvoir disposer des blocs de jonction standards permettant l'adaptation ou le remplacement immédiat de la logique constituée par une carte de circuit imprimé, indépendamment du câblage des informations d'entrée et de sortie, et aussi indépendamment du câblage des tensions d'alimentation propres aux circuits constitutifs d'une logique. D'autre part, il convient que cette adaptation ou cette modification puisse être opérée en toute indépendance au sein d'une barrette de raccordement constituée par un empilage côte à côte de blocs de jonction identiques ou associables, sans avoir à modifier le câblage ou le montage des éléments adjacents.A terminal block thus normally comprises terminals connected to an input circuit, terminals connected to an output circuit and terminals for connection to a printed circuit board. However, it is advantageous, when performing an installation, to be able to have standard terminal blocks allowing the immediate adaptation or replacement of the logic constituted by a printed circuit board, independently of the wiring of the input and output information. , and also independently of the wiring of the supply voltages specific to the circuits constituting a logic. On the other hand, this adaptation or modification should be able to be carried out independently within a connection strip constituted by a stacking side by side of identical or associable terminal blocks, without having to modify the wiring or the mounting of adjacent elements.

Or il est connu de réaliser des blocs pour barrette de raccordement qui comportent des circuits imprimés ainsi que le montre la publication FR-A-2 164003. Dans ce cas, une carte de circuit imprimé est fixée de façon que son plan englobe l'axe de la barrette. Si une telle solution est envisageable pour des cartes comportant de nombreuses connexions, elle présente l'inconvénient d'occuper une grande longueur de la barrette, alors qu'une disposition différente pourrait éviter un tel inconvénient.However, it is known to produce blocks for terminal strip which include printed circuits as shown in publication FR-A-2 164003. In this case, a printed circuit board is fixed so that its plane includes the axis of the bar. If such a solution is possible for cards with many connections, it has the disadvantage of occupying a long length of the bar, while a different arrangement could avoid such a disadvantage.

La publication FR­A­2 358 757 décrit un bloc de jonction, pour barrette de raccordement à éléments amovibles, apte à être connecté à une barre de distribution, qui permet donc d'alimenter divers éléments à partir d'une même barre. Toutefois, la réalisation présentée ne se prête pas à la mise en oeuvre de blocs comportant des cartes de circuit imprimé pour laquelle elle n'est pas prévue.The publication FRA2 358 757 describes a terminal block for a terminal block with removable elements, suitable for being connected to a distribution bar, which therefore makes it possible to supply various elements from the same bar. However, the embodiment presented does not lend itself to the use of blocks comprising printed circuit boards for which it is not intended.

Pour répondre aux besoins évoqués ci-dessus, la présente invention propose donc une barrette de raccordement et un bloc de jonction à carte de circuit imprimé destiné à cette barrette, ne possédant pas les défauts évoqués ci-dessus.To meet the needs mentioned above, the present invention therefore provides a connection strip and a terminal block with printed circuit board intended for this strip, not having the faults mentioned above.

Selon l'invention, une barrette de raccordement électrique constituée d'un support et d'une rangée de blocs de jonction, les blocs étant montés côte à côte sur ledit support et étant prévus pour recevoir par leurs faces supérieures des contacts faisant saillie à partir d'un bord d'une carte à circuits imprimés, et ayant des bornes de raccordement extérieur sur au moins une face latérale, qui est parallèle à l'axe de la barrette, est caractérisée par le fait que les blocs sont prévus pour recevoir les cartes transversalement par rapport à l'axe de la barrette et en ce que ladite face supérieure de chaque bloc comporte des supports isolants recevant des barres électriques communes qui sont disposées parallèlement à l'axe de la barrette et en regard d'un premier groupe desdits contacts qui sont en forme de lyres, lesdites barres fournissant aux cartes des tensions d'alimentation par l'intermédiaire des contacts du premier groupe, des plots de contact reliés auxdites bornes de raccordement extérieur étant prévus en regard d'une deuxième groupe desdits contacts également en forme de lyres.According to the invention, an electrical connection strip consisting of a support and a row of terminal blocks, the blocks being mounted side by side on said support and being designed to receive by their upper faces contacts projecting from of an edge of a printed circuit board, and having external connection terminals on at least one lateral face, which is parallel to the axis of the strip, is characterized in that the blocks are designed to receive the cards transversely to the axis of the bar and in that said upper face of each block comprises insulating supports receiving common electrical bars which are arranged parallel to the axis of the bar and facing a first group of said contacts which are in the form of lyres, said bars supplying the supply voltages to the cards via the contacts of the first group, contact pads connected to said connection terminals exterior being provided opposite a second group of said contacts also in the form of lyres.

Un bloc d'une telle barrette est de préférence caractérisé par le fait que les supports isolants sont constitués par deux rangées parallèles de dents formant des encoches pour l'insertion des barres électriques communes, lesdites rangées délimitant entre elles un espace libre pour les plages de contact sur les barres et les plots.A block of such a bar is preferably characterized in that the insulating supports consist of two parallel rows of teeth forming notches for the insertion of common electrical bars, said rows delimiting between them a free space for the ranges of contact on bars and studs.

En ce qui concerne certaines caractéristiques d'une mise en oeuvre préférée de l'invention, référence expresse est faite aux revendications 3 à 6.With regard to certain characteristics of a preferred implementation of the invention, express reference is made to claims 3 to 6.

L'invention sera décrite ci-après à l'aide d'un exemple de réalisation illustré dans les dessins.

  • La figure 1 est une vue en perspective d'ensemble d'un bloc de jonction selon l'invention.
  • La figure 2 est une vue en perspective éclatée du bloc de jonction selon la figure 1, sans capot de protection.
  • La figure 3 est une vue de la face transversale du bloc de jonction selon la figure 1, avec semi-coupe, sans pied de fixation, ni support.
  • La figure 4 est une vue agrandie en coupe longitudinale selon IV-IV du bloc de jonction selon la figure 3.
The invention will be described below using an embodiment illustrated in the drawings.
  • Figure 1 is an overall perspective view of a terminal block according to the invention.
  • Figure 2 is an exploded perspective view of the terminal block according to Figure 1, without protective cover.
  • Figure 3 is a view of the transverse face of the terminal block according to Figure 1, with semi-section, without mounting foot, or support.
  • FIG. 4 is an enlarged view in longitudinal section on IV-IV of the terminal block according to FIG. 3.

Dans les figures, on a désigné par 1 l'ensemble d'une embase de bloc de jonction comportant un socle 2 et une coiffe 3 en matériau plastique isolant.In the figures, 1 denotes the assembly of a junction block base comprising a base 2 and a cover 3 made of insulating plastic material.

Le socle 2 comporte à sa base un pied de fixation amovible 11 monté sur un profilé support 12. Un tel pied de fixation est par exemple identique à celui décrit dans la publication FR-A-2 133 277. Il est ainsi loisible de disposer côte à côte le long du profilé support un ensemble de blocs de jonction pour réaliser une barrette de raccordement non représentée dans les figures. Un autre mode de fixation des blocs de jonction pourrait être obtenu à l'aide de vis de fixation disposées dans des évidements 13 d'un côté de l'embase et boulonnées au travers d'une plaque support selon un procédé largement utilisé dans cette technique.The base 2 has at its base a removable fixing foot 11 mounted on a support profile 12. Such a fixing foot is for example identical to that described in the publication FR-A-2 133 277. It is thus possible to have side side by side along the support profile, a set of terminal blocks for producing a connection strip not shown in the figures. Another way of attaching terminal blocks could be obtained by means of fixing screws arranged in recesses 13 on one side of the base and bolted through a support plate according to a process widely used in this technique.

Le socle 2 présente, du côté avant et du côté arrière, sur sa face supérieure, deux encoches transversales 20 séparant entre elles trois bandes 21 contre lesquelles sont appliquées horizontalement des barres de liaison telles que 41, 42, 43 reliant chacune une borne 4 de raccordement extérieur à un plot de contact interne 40. Chaque borne 4, dont une seule est représentée dans la figure 2, est constituée par un étrier à vis de serrage 44. Les barres de liaison 41, 42 et 43 sont contrecoudées de manière à ce que les plots de contact soient disposés verticalement et dans un même alignement transversal avec un espacement donné.The base 2 has, on the front side and on the rear side, on its upper face, two transverse notches 20 separating between them three bands 21 against which are applied connecting bars such as 41, 42, 43 each connecting a terminal 4 of external connection to an internal contact pad 40. Each terminal 4, only one of which is shown in FIG. 2, is constituted by a clamping screw clamp 44. The connecting bars 41, 42 and 43 are counter-bent so that that the contact pads are arranged vertically and in the same transverse alignment with a given spacing.

D'autre part, les barres de liaison sont maintenues en place par une plaquette 45 présentant des ailes 46 engagées dans les encoches 20 et constituant des séparateurs d'isolation entre les barres.On the other hand, the connecting bars are held in place by a plate 45 having wings 46 engaged in the notches 20 and constituting insulation separators between the bars.

Le socle 2 présente aussi sur ses extrémités avant et arrière des becs 23 destinés à coopérer avec une nervure 31 disposée à la partie inférieure de la coiffe 3 pour réaliser un accrochage élastique de la coiffe sur l'embase.The base 2 also has on its front and rear ends nozzles 23 intended to cooperate with a rib 31 disposed at the lower part of the cap 3 to produce an elastic hooking of the cap on the base.

La coiffe 3 comporte sur l'un de ses côtés des ouvertures 14 et 15 destinées à permettre la mise en place des dispositifs de fixation du socle 2 sur son support.The cover 3 has on one of its sides openings 14 and 15 intended to allow the establishment of the devices for fixing the base 2 on its support.

Pour permettre d'accéder aux bornes 4 avant et arrière, la coiffe 3 présente sur ses faces avant et arrière des ouvertures 30 et sur sa face supérieure des ouvertures 32. Dans sa partie centrale, la face supérieure de la coiffe 3 constitue, de part et d'autre d'un espace libre 33 visible dans les figures 2 et 4, des supports isolants 34 formés par une succession de dents 35 entre lesquelles sont intercalées longitudinalement des barres électriques 5. Aux extrémités des supports isolants 34 la face supérieure de la coiffe 3 comporte, au droit des intervalles entre deux dents 35 en regard et dans l'espace libre 33, des fentes longitudinales 36 visibles dans la figure 2 grâce à un arraché de dehts 35 et permettant le passage des plots de contact 40 dont l'espacement correspond à celui des dents.To allow access to the front and rear terminals 4, the cover 3 has openings 30 on its front and rear faces and on its upper face openings 32. In its central part, the upper face of the cover 3 constitutes and on the other side of a free space 33 visible in FIGS. 2 and 4, insulating supports 34 formed by a succession of teeth 35 between which electrical bars are inserted longitudinally 5. At the ends of the insulating supports 34 the upper face of the cap 3 comprises, in line with the intervals between two facing teeth 35 and in the free space 33, longitudinal slots 36 visible in FIG. 2 thanks to a tear-off of dehts 35 and allowing the passage of the contact pads 40, the spacing corresponds to that of the teeth.

L'intervalle 33 laisse ainsi apparaître entre les deux rangées de dents des supports isolants 34 une plage de contact des barres 5, d'une part, et des plots 40, d'autre part.The interval 33 thus lets appear between the two rows of teeth of the insulating supports 34 a contact area of the bars 5, on the one hand, and of the studs 40, on the other hand.

Entre les extrémités des supports isolants 34 et les ouvertures 32, la face supérieure de la coiffe 3 présente deux épaulements 37 comportant chacun une glissière verticale 38 destinée à coopérer avec un doigt de guidage 61 disposé à la partie inférieure d'un châssis isolant 6. Les faces avant et arrière du châssis 6 présentent un bec inférieur 62 destiné au verrouillage du châssis 6 sur la coiffe 3 à l'aide d'un ressort 47 dont les extrémités sont engagées dans des perçages 39 des côtés de l'épaulement 37.Between the ends of the insulating supports 34 and the openings 32, the upper face of the cover 3 has two shoulders 37 each comprising a vertical slide 38 intended to cooperate with a guide finger 61 disposed at the bottom of an insulating frame 6. The front and rear faces of the chassis 6 have a lower spout 62 intended for locking the chassis 6 on the cover 3 using a spring 47, the ends of which are engaged in holes 39 on the sides of the shoulder 37.

Le châssis 6 présente à sa partie inférieure un peigne formé par une série de dents 63, dont le pas correspond à celui des espacements des barres 5 et des plots de contact 40, les dents étant destinées à être insérées dans ces espacements dans l'espace 33.The chassis 6 has at its lower part a comb formed by a series of teeth 63, the pitch of which corresponds to that of the spacings of the bars 5 and of the contact pads 40, the teeth being intended to be inserted into these spacings in space. 33.

Le corps du châssis 6 comporte sur l'un de ses côtés une série d'alvéoles formés chacun par une ouverture latérale 64 débouchant sur une lumière verticale 65 débouchant dans l'intervalle formé entre deux dents 63 successives.The body of the chassis 6 has on one of its sides a series of cells each formed by a lateral opening 64 opening onto a vertical lumen 65 opening into the gap formed between two successive teeth 63.

Des lyres de contact 9, munies sur une face d'un picot supérieur 91 et d'un picot inférieur 92, et sur la face opposée d'un ergot 93, sont insérées à travers les ouvertures 64 et les lumières 65 de telle sorte que les picots inférieurs 92 reposent contre la partie inférieure des ouvertures 64 et que les ergots 93 sont verrouillés par déformation élastique des parties en présence contre un épaulement 66 des lumières 64. Lorsque les dents 63 du châssis 6 sont embrochées dans l'espace 33 dans les espacements entre les barres 5 et les plots 40, les lyres de contact 9 viennent pincer les plages de contact apparentes des barres 5 et des plots 40.Contact lyres 9, provided on one face with an upper pin 91 and a lower pin 92, and on the opposite face with a lug 93, are inserted through the openings 64 and the slots 65 so that the lower pins 92 rest against the lower part of the openings 64 and that the lugs 93 are locked by elastic deformation of the parts present against a shoulder 66 of the slots 64. When the teeth 63 of the chassis 6 are plugged into space 33 in spacings between the bars 5 and the pads 40, the contact lyres 9 pinch the apparent contact pads of the bars 5 and the pads 40.

Par ailleurs, le châssis 6 présente à sa partie supérieure, sur le côté comportant les picots 91 et 92, des tétons 60 destinés à coopérer dans les orifices 70 d'une carte de circuit imprimé 7 pour permettre un encliquetage de la carte 7 contre le châssis 6, tandis que les picots 91 et 92 pénètrent dans des alvéoles de contact 71 et 72 avec le circuit imprimé. La fixation de la carte 7 sur le châssis 6 peut être complétée par vissage de vis 78 dans un taraudage des tétons 60. Ainsi, quand la carte 7 est fixée sur le châssis 6, il est possible par simple manoeuvre d'insertion ou de retrait du châssis sur la coiffe 3 de l'embase 2 d'embrocher ou de débrocher les lyres de contact 9 solidaires de cette carte à sa partie inférieure.Furthermore, the chassis 6 has at its upper part, on the side comprising the pins 91 and 92, pins 60 intended to cooperate in the orifices 70 of a printed circuit board 7 to allow the card 7 to snap against the chassis 6, while the pins 91 and 92 penetrate into contact cells 71 and 72 with the printed circuit. The fixing of the card 7 on the chassis 6 can be completed by screwing screws 78 into a tapping of the pins 60. Thus, when the card 7 is fixed on the chassis 6, it is possible by simple insertion or removal operation. of the chassis on the cover 3 of the base 2 of plugging in or removing the contact lyres 9 secured to this card at its lower part.

En outre, le capot isolant 8 peut être enfilé sur la partie supérieure de la carte 7 et solidarisé avec le châssis 6. A cet effet, le châssis 6 comporte sur ses faces avant et arrière un bec 66 susceptible de coopérer avec une encoche 80 des faces avant et arrière du capot.In addition, the insulating cover 8 can be slipped onto the upper part of the card 7 and secured to the chassis 6. To this end, the chassis 6 has on its front and rear faces a spout 66 capable of cooperating with a notch 80 of the front and back of the hood.

La face supérieure du capot comporte des ouvertures 81 et 82 permettant d'accéder à des moyens de contrôle et de commande du circuit imprimé constitués, par exemple, par des diodes luminescentes 73, des résistances réglables 74 et des bornes 76 du circuit imprimé, lesdits moyens étant disposés sur la partie supérieure de la carte 7. Des ouvertures d'aération 83 sont ménagées d'autre part sur les faces avant et arrière de la carte 7.The upper face of the cover has openings 81 and 82 allowing access to control and command means of the printed circuit consisting, for example, of light-emitting diodes 73, adjustable resistors 74 and terminals 76 of the printed circuit, said means being arranged on the upper part of the card 7. Ventilation openings 83 are formed on the other hand on the front and rear faces of the card 7.
