Description

La présente invention concerne un dispositif d'interface comprenant une embase, constituée par un profilé comportant un corps central bordé par deux flancs longitudinaux supérieur et inférieur, une carte à circuit imprimé montée sur l'embase, et au moins un bloc d'interface comportant un bornier muni à l'avant d'une rangée de bornes alignées, fixé et relié électriquement à l'arrière au circuit imprimé par des fiches de connexion soudées à celui-ci.The present invention relates to an interface device comprising a base, constituted by a profile comprising a central body bordered by two upper and lower longitudinal sides, a printed circuit board mounted on the base, and at least one interface block comprising a terminal block provided at the front with a row of aligned terminals, fixed and electrically connected at the rear to the printed circuit by connection plugs soldered thereto.

Un dispositif d'interface est destiné à être interposé électriquement entre une unité de traitement telle qu'un automate programmable et un équipement électrique susceptible d'être exploité ou commandé par l'unité de traitement. La fonction d'interface est assurée grâce à des blocs d'interface comportant couramment un premier bornier, pour la connexion de câbles assurant la transmission de signaux d'entrée en provenance d'émetteurs vers l'automate ou la transmission de signaux de sortie depuis l'automate à destination d'actionneurs. Les blocs d'interface peuvent éventuellement comporter un second bornier, disposé en dessous du premier bornier, pour une utilisation identique à celle du premier bornier ou pour une distribution d'une polarité de l'alimentation. Les borniers sont chacun munis d'une rangée de bornes de raccordement alignées et montées sur des fiches de connexion soudées sur le circuit imprimé du dispositif, la rangée du second bornier étant parallèle et décalée en profondeur par rapport à celle du premier bornier.An interface device is intended to be electrically interposed between a processing unit such as a programmable controller and electrical equipment capable of being operated or controlled by the processing unit. The interface function is provided by interface blocks commonly comprising a first terminal block, for the connection of cables ensuring the transmission of input signals from transmitters to the PLC or the transmission of output signals from the PLC for actuators. The interface blocks can optionally include a second terminal block, disposed below the first terminal block, for use identical to that of the first terminal block or for distribution of a polarity of the power supply. The terminal blocks are each provided with a row of connection terminals aligned and mounted on connection plugs welded to the printed circuit of the device, the row of the second terminal block being parallel and offset in depth with respect to that of the first terminal block.

Il est parfois utile de prévoir dans un tel dispositif un troisième bornier pouvant par exemple être utilisé pour un raccordement à la terre ou pour permettre une distribution de la polarité complémentaire de l'alimentation; ce bornier présente une rangée de bornes prévue en parallèle aux deux autres rangées et munie de fiches de connexion soudées au même circuit imprimé du dispositif. Dans l'état de la technique actuel, un dispositif d'interface est donc prévu lors de sa fabrication pour comprendre soit une, soit deux, soit trois rangées de bornes; il est donc impossible pour un utilisateur qui possède un dispositif à deux borniers d'ajouter à tout moment un bornier supplémentaire pour réaliser une troisième rangée de bornes.It is sometimes useful to provide in such a device a third terminal block which can, for example, be used for an earth connection or to allow distribution of the complementary polarity of the power supply; this terminal block has a row of terminals provided in parallel to the other two rows and provided with connection plugs soldered to the same printed circuit of the device. In the current state of the art, an interface device is therefore provided during its manufacture to include either one, two, or three rows of terminals; it is therefore impossible for a user who has a device with two terminals to add at any time an additional terminal to make a third row of terminals.

L'invention vise par conséquent à proposer un dispositif d'interface auquel il est facile d'ajouter un bornier supplémentaire.The invention therefore aims to provide an interface device to which it is easy to add an additional terminal block.

Selon l'invention, le dispositif est caractérisé en ce que le bornier additif est dissocié du bloc d'interface et de la carte à circuit imprimé et est monté sous l'embase grâce à des moyens de retenue qui coopèrent avec celle-ci, de préférence par encliquetage avec au moins une rainure longitudinale prévue dans le flanc inférieur du profilé de préférence dans la face inférieure de ce flanc.According to the invention, the device is characterized in that the additive terminal block is dissociated from the interface block and the printed circuit board and is mounted under the base by means of retaining means which cooperate with it, preferably by snap-fastening with at least one longitudinal groove provided in the lower flank of the profile, preferably in the lower face of this flank.

Les moyens de retenue peuvent avantageusement consister en des éléments d'encliquetage, notamment à forme en M, solidaires de la face supérieure du corps du bornier additif. Ces éléments comprennent une âme, des pieds latéraux se raccordant à l'âme et prenant appui sur ladite face supérieure, et une languette élastique solidaire de l'âme et destinée à s'encliqueter de manière irréversible dans la rainure du profilé.The retaining means may advantageously consist of snap-fastening elements, in particular M-shaped, integral with the upper face of the body of the additive terminal block. These elements include a core, lateral feet connecting to the core and bearing on said upper face, and an elastic tongue secured to the core and intended to snap irreversibly into the groove of the profile.

Les moyens de retenue sont de préférence disposés en alternance suivant deux axes parallèles longitudinaux du bornier additif et coopèrent avec deux rainures parallèles longitudinales de la face inférieure du flanc inférieur du profilé. Cette disposition assure un meilleur maintien mécanique du bornier à l'embase.The retaining means are preferably arranged alternately along two longitudinal parallel axes of the additive terminal block and cooperate with two longitudinal parallel grooves on the underside of the lower flank of the profile. This arrangement ensures better mechanical retention of the terminal block at the base.

De plus, la face supérieure du corps du bornier additif présente des formes qui coopèrent avec une rainure profilée complémentaire de la face inférieure de l'embase pour solidariser le bornier à l'embase.In addition, the upper face of the body of the additive terminal block has shapes which cooperate with a profiled groove complementary to the lower face of the base to secure the terminal block to the base.

L'invention va maintenant être décrite avec plus de détail en se référant à titre d'exemple aux dessins annexés parmi lesquels:

  • la figure 1 représente une vue éclatée du dispositif d'interface selon l'invention;
  • la figure 2 représente une vue en coupe du dispositif.
The invention will now be described in more detail with reference, by way of example, to the accompanying drawings, in which:
  • Figure 1 shows an exploded view of the interface device according to the invention;
  • Figure 2 shows a sectional view of the device.

Le dispositif d'interface, visible à la figure 1, est destiné à être interposé électriquement entre une unité de traitement, par exemple un automate programmable, et un équipement électrique susceptible d'être exploité ou commandé par cette unité.The interface device, visible in Figure 1, is intended to be electrically interposed between a processing unit, for example a programmable controller, and electrical equipment capable of being operated or controlled by this unit.

Le dispositif comprend une embase 1, une carte 2 à circuit imprimé, un bloc d'alimentation 3, et au moins un bloc d'interface 4. Le bloc d'interface 4 est muni à l'avant et à sa partie inférieure d'un bornier supérieur intégré 5 et d'un bornier inférieur rapporté 6 parallèle et décalé en profondeur par rapport au bornier 5. Le dispositif comprend en outre un bornier additif 7 destiné à être monté sous l'embase 1 et à être disposé parallèlement et de façon décalée en profondeur par rapport aux deux autres borniers.The device comprises a base 1, a printed circuit card 2, a power supply unit 3, and at least one interface block 4. The interface block 4 is provided at the front and at its lower part with an integrated upper terminal block 5 and an attached lower terminal block 6 parallel and offset in depth with respect to the terminal block 5. The device further comprises an additive terminal block 7 intended to be mounted under the base 1 and to be arranged parallel and so offset in depth from the other two terminal blocks.

L'embase 1 consiste en un profilé réalisé par extrusion apte à être monté par des moyens usuels de fixation sur un rail solidaire d'une paroi ou platine. Le profilé comporte d'un seul tenant un corps central 10, et des flancs longitudinaux supérieur 11 et inférieur 12 disposés en avancée respectivement sur les bords dudit corps.The base 1 consists of a profile produced by extrusion capable of being mounted by conventional means of attachment to a rail secured to a wall or plate. The profile comprises in one piece a central body 10, and upper 11 and lower 12 longitudinal sides disposed in advance respectively on the edges of said body.

Les flancs 11 et 12 présentent respectivement sur leur face interne une glissière longitudinale 13, et le flanc inférieur 12 présente vers le dessous, dans sa face externe ou inférieure 12a, deux rainures parallèles longitudinales 14 et 15.The sidewalls 11 and 12 respectively have on their internal face a longitudinal slide 13, and the lower side 12 has below, in its external or lower face 12a, two parallel longitudinal grooves 14 and 15.

La carte 2, de faible épaisseur, est montée sur l'embase 1 de façon que ses chants longitudinaux 21 soient logés dans les glissières 13. Elle comprend un circuit imprimé et un connecteur 20 multi-voies soudé à ce circuit; le connecteur est destiné à être raccordé à l'automate, et le circuit imprimé permet de relier chaque voie du connecteur avec une voie du bloc d'interface 4 ou du bloc d'alimentation 3.The card 2, of small thickness, is mounted on the base 1 so that its longitudinal edges 21 are housed in the slides 13. It comprises a printed circuit and a multi-way connector 20 soldered to this circuit; the connector is intended to be connected to the PLC, and the printed circuit makes it possible to connect each channel of the connector with a channel of the interface block 4 or the power supply 3.

Le bloc d'alimentation 3 est muni de bornes d'alimentation 30 pour distribuer la tension d'alimentation vers l'unité de traitement et de bornes d'alimentation 31 pour distribuer la tension de contrôle vers l'équipement électrique.The power supply unit 3 is provided with supply terminals 30 to distribute the supply voltage to the processing unit and supply terminals 31 to distribute the control voltage to the electrical equipment.

Le bloc d'interface 4 comprend un boîtier 40 qui comporte dans sa partie inférieure le bornier supérieur intégré 5.The interface block 4 comprises a box 40 which has in its lower part the integrated upper terminal block 5.

Le bornier 5 présente une rangée de bornes 50 alignées. Chaque borne 50 est une borne à vis, à cage ascenseur 51, et munie d'une fiche de connexion 52 soudée au circuit imprimé pour permettre de lui relier électriquement un câble inséré dans la borne. La fiche de connexion 52 assure en outre la fixation mécanique du boîtier 40 à la carte 2.Terminal block 5 has a row of aligned terminals 50. Each terminal 50 is a screw terminal, with a lift cage 51, and provided with a connection plug 52 soldered to the printed circuit to allow it to electrically connect a cable inserted in the terminal. The connection plug 52 also ensures the mechanical fixing of the housing 40 to the card 2.

Le boîtier 40 peut par ailleurs loger dans sa partie supérieure des diffuseurs de lumière 81 qui sont en vis à vis de diodes électroluminescentes 82 soudées au circuit imprimé et qui débouchent à l'avant du boîtier sur des fenêtres 80.The housing 40 can moreover accommodate, in its upper part, light diffusers 81 which are opposite light-emitting diodes 82 soldered to the printed circuit and which open at the front of the housing onto windows 80.

Le bornier inférieur rapporté 6 du bloc d'interface est monté en dessous du bornier 5. Il comprend un corps 60 qui présente sur sa face supérieure 60a des nervures transversales 61 qui coopèrent avec des nervures prévues sur la face inférieure du boîtier 40. La face inférieure 60b du corps 60 se trouve au même niveau que la face externe horizontale 12a du flanc inférieur 12 de l'embase.The lower reported terminal block 6 of the interface block is mounted below the terminal block 5. It comprises a body 60 which has on its upper face 60a transverse ribs 61 which cooperate with ribs provided on the lower face of the housing 40. The face lower 60b of the body 60 is at the same level as the horizontal external face 12a of the lower side 12 of the base.

Le bornier 6 comprend une rangée de bornes à vis 62 de type à cage ascenseur alignées, qui sont munies de fiches de connexion 63 soudées au circuit imprimé. Cette deuxième rangée de bornes 62 est disposée parallèlement à la rangée de bornes 50 et décalée en profondeur par rapport à cette dernière.Terminal block 6 comprises a row of screw terminals 62 of the aligned elevator cage type, which are provided with connection plugs 63 soldered to the printed circuit. This second row of terminals 62 is arranged parallel to the row of terminals 50 and offset in depth with respect to the latter.

Le bornier additif 7 comprend une rangée de bornes 70 alignées reliées entre elles qui peuvent par exemple être utilisées pour un raccordement à la terre ou pour une distribution de la polarité de l'alimentation opposée à la polarité distribuée par le bornier 6.The additive terminal block 7 comprises a row of aligned terminals 70 connected together which can for example be used for an earth connection or for a distribution of the polarity of the supply opposite to the polarity distributed by the terminal block 6.

Le bornier est constitué d'un corps 71, d'une carte additive à circuit imprimé 72, et d'un socle 73. Les bornes 70 à vis de type à cage ascenseur sont munies de fiches de connexion 74 qui sont soudées au circuit imprimé de la carte additive 72 pour réaliser une liaison électrique entre ces fiches, et contribuer à la fixation mécanique de la carte additive 72 au corps 71. Le socle 73 est destiné à être monté à l'arrière du corps 71 afin de protéger la carte à circuit imprimé et fermer le corps du bornier; cette fermeture arrière du bornier est réalisée grâce à des moyens d'accrochage 75 prévus sur le socle 73 qui s'engagent dans des évidements 76 du corps 71.The terminal block consists of a body 71, an additive printed circuit board 72, and a base 73. The screw terminal 70 of the elevator cage type are provided with connection plugs 74 which are soldered to the printed circuit. of the additive card 72 to make an electrical connection between these plugs, and to contribute to the mechanical fixing of the additive card 72 to the body 71. The base 73 is intended to be mounted at the rear of the body 71 in order to protect the printed circuit board and close the terminal block body; this rear closing of the terminal block is carried out by means of attachment means 75 provided on the base 73 which engage in recesses 76 in the body 71.

Le bornier additif forme ainsi un ensemble monobloc et il est monté sous l'embase 1 du dispositif en dessous du bornier inférieur 6 de manière à disposer la rangée de bornes 70 de façon parallèle et décalée en profondeur par rapport aux deux autres rangées de bornes 50 et 60. Un ergot de positionnement 71b est prévu de préférence sur la surface 71a du bornier additif pour coopérer avec un évidement du bloc d'interface ou de la surface 60b du bornier 6 afin de permettre un positionnement vertical et parallèle des bornes 70 avec les bornes 50.The additive terminal block thus forms a monobloc assembly and it is mounted under the base 1 of the device below the lower terminal block 6 so as to arrange the row of terminals 70 in a parallel manner and offset in depth with respect to the other two rows of terminals 50 and 60. A positioning lug 71b is preferably provided on the surface 71a of the additive terminal block to cooperate with a recess in the interface block or on the surface 60b of the terminal block 6 in order to allow vertical and parallel positioning of the terminals 70 with the terminals 50.

Le bornier 7 est fixé à l'embase grâce des moyens de retenue 77. Ces moyens sont solidaires de la face supérieure 71a du corps 71 du bornier, ils sont disposés en alternance suivant deux axes parallèles longitudinaux du corps 71 et sont aptes à coopérer avec les rainures 14 et 15 du profilé. La face supérieure horizontale 71a du corps 71 du bornier est ainsi appliquée contre la face inférieure horizontale 12a de l'embase.The terminal block 7 is fixed to the base by means of retaining means 77. These means are integral with the upper face 71a of the body 71 of the terminal block, they are arranged alternately along two longitudinal parallel axes of the body 71 and are able to cooperate with the grooves 14 and 15 of the profile. The horizontal upper face 71a of the body 71 of the terminal block is thus applied against the horizontal lower face 12a of the base.

Les moyens de retenue 77 sont du type à encliquetage ou analogue. Ils consistent en des éléments de forme en M qui comportent chacun une âme 78, et deux pieds latéraux 79 disposés respectivement aux deux extrémités de l'âme, et prenant appui de façon solidaire sur la face supérieure 71a. L'âme présente en son milieu une languette élastique 78a à flanc oblique destinée à être encliquetée de manière irréversible dans la rainure 14 ou 15.The retaining means 77 are of the snap type or the like. They consist of M-shaped elements which each comprise a core 78, and two lateral feet 79 respectively disposed at the two ends of the core, and bearing in an integral manner on the upper face 71a. The core has in its middle an elastic tongue 78a with an oblique flank intended to be snapped irreversibly into the groove 14 or 15.

Pour monter le bornier additif sous l'embase 1, on le positionne sous le bloc d'interface 4 grâce à l'ergot de positionnement 71b, on engage l'âme 78 des moyens de retenue dans les rainures 14 et 15 du profilé. Enfin, on exerce sur le bornier une force sensiblement verticale F dirigée de bas en haut ce qui a pour effet de comprimer les languettes élastiques 78a au niveau des ouvertures 14a et 15a des rainures puis d'asseoir les chants 78b des languettes sur les rebords internes 14b et 15b des rainures. Les éléments 77 sont disposés en alternance de manière opposée selon chaque axe de façon que, les languettes se trouvant orientées de manière opposée, les chants 78b des languettes s'appuient de manière opposée sur les rebords 14b et 15b des rainures pour une meilleure tenue mécanique du bornier. Pour renforcer encore cette tenue, il est possible de solidariser, par exemple par collage, dans une rainure profilée complémentaire 12b de la face 12a de l'embase des formes coopérantes 71c prévues sur la surface 71a du bornier.To mount the additive terminal block under the base 1, it is positioned under the interface block 4 thanks to the positioning lug 71b, the core 78 of the retaining means is engaged in the grooves 14 and 15 of the profile. Finally, a substantially vertical force F directed from the bottom up is exerted on the terminal block, which has the effect of compressing the elastic tongues 78a at the openings 14a and 15a of the grooves and then seating the edges 78b of the tongues on the internal edges. 14b and 15b of the grooves. The elements 77 are arranged alternately in opposite directions along each axis so that, the tongues being oriented in opposite directions, the edges 78b of the tongues bear oppositely on the edges 14b and 15b of the grooves for better mechanical strength. of the terminal block. To further strengthen this holding, it is possible to secure, for example by gluing, in a complementary profiled groove 12b of the face 12a of the base of the cooperating shapes 71c provided on the surface 71a of the terminal block.

Le raccordement électrique du bornier additif se fait à l'aide d'un fil électrique extérieur, câblé par l'utilisateur entre une borne 70 et par exemple une borne 31 du bloc d'alimentation 3, pour une distribution de polarité de l'alimentation.The electrical connection of the additive terminal block is made using an external electric wire, wired by the user between a terminal 70 and for example a terminal 31 of the power supply unit 3, for a distribution of polarity of the power supply. .
