Description

Dispositif de connexion décentralisée d'un organe à une unité de commande programmable. Device for decentralized connection of an organ to a programmable control unit.
La présente invention concerne un dispositif de connexion pour chacun des organes d'une installation in¬ dustrielle à l'unité de commande programmable gérant le fonctionnement de cette installation. Dans un avenir proche, la liaison entre les dif férents organes d'une machine et l'unité de commande de son fonctionnement sera réalisée de manière décentralisée, c'est-à-dire que les moyens électroniques d'interface et de convers on entre des signaux aptes à être exploités par l'unité de commande et des signau aptes à être exploités par les organes, seront disposés au plus près des organes eux- mêmes pour rationaliser les câblages et permettre, d'une manière générale, une conception, une réalisation, un entre¬ tien et une évolution de l'installation beaucoup plus simples que ceux actuellement possibles.The present invention relates to a device for connecting each of the members of an industrial installation to the programmable control unit managing the operation of this installation. In the near future, the connection between the various organs of a machine and the control unit for its operation will be carried out in a decentralized manner, that is to say that the electronic means of interface and convers on between signals suitable for being operated by the control unit and signals suitable for being operated by the members, will be arranged as close as possible to the members themselves in order to rationalize the cabling and allow, in general, a design, a realization, maintenance and development of the installation much simpler than those currently possible.
Dans ce contexte, on prévoit que La Liaison présentera une Ligne générale de circulation de signaux in¬ formationnels reliés à l'unité de commande le long de laquell on pourra implanter des dérivations en direction de chaque organe à gérer, les moyens d'interface et d'adaptation étant concentrés sur ces points de dérivation. On prévoit également de mettre à la disposition de la liaison, à ces points de dérivat on, une ou plusieurs sources d'énergie de manière qu' entre le point de dérivation et L'organe correspondant, il n'existe qu'un seul lien Le long duquel signaux et énergie puissent circuler. Chaque point de dérivation se présentera sous la forme d'un support définissant un plan de pose standard sur lequel le raccordement de n'importe quel organe doit pouvoir être réalisé, ce plan de pose comportant donc rassemblées dans un arrangement prédéterminé unique, des bornes de connexions pour des voies électroniques issues de l'uni.té de commande programmable et des bornes de connexion pour des lignes électriques d'ali entation issues d'une ou plusieurs sources. Les moyens d'interface et d'adaptation, qui sont à interposer entre l'unité centrale et l 'organe, sont nécessairement spécifiques de la nature de l 'organe. Ainsi, à titre d'exemple, on mentionnera l 'existence d'organes émetteurs de données, tels que des détecteurs ou capteurs et des organes récepteurs de données appelés préactionneurs qui peuvent consister en des contacteurs, des élect rovannes, ... On conçoit que l 'interface électronique nécessaire pour le dialogue de l 'unité de commande avec les organes soit diffé¬ rent d'un type à L 'autre, le sens de circulation du signal et de l ' information résultante ou de L'information et du signal résultant étant opposé dans La Liaison d'un type d'organe à l 'autre .In this context, it is foreseen that La Liaison will present a general line of circulation of in¬ training signals connected to the control unit along which it will be possible to set up branches in the direction of each organ to be managed, the interface means and of adaptation being concentrated on these points of derivation. There are also plans to make one or more energy sources available to the link at these taps, so that there is only one link between the tap point and the corresponding device. Along which signals and energy can flow. Each point of derivation will be in the form of a support defining a standard laying plane on which the connection of any member must be able to be made, this laying plan therefore comprising gathered in a unique predetermined arrangement, terminals connections for electronic channels from the programmable control unit and connection terminals for power supply lines from one or more sources. The means of interface and adaptation, which are to be interposed between the central unit and the organ, are necessarily specific to the nature of the organ. Thus, by way of example, mention will be made of the existence of data transmitting members, such as detectors or sensors and data receiving members called preactuators which may consist of contactors, electromagnetic valves, etc. that the electronic interface necessary for the dialogue of the control unit with the organs be different from one type to another, the direction of circulation of the signal and the resulting information or of information and resulting signal being opposed in The Binding of a type of organ to the other.
En outre, à l' ntérieur de chaque type il exist des organes de nature différente. On citera les détecteurs deux fi ls, Les détecteurs trois fiLs, Les capteurs à contact pour ce qui concerne les organes émetteurs et pour les autres, des organes récepteurs à alimentation directe depuis la source d'énergie disponible aux bornes de connexion du plan de pose ou à alimentation séparée par une ligne sur laquelle il convient d'agir pour transmettre la donnée. On comprend donc qu'i l fai lle mettre en oeuvre des moyens d'adaptation, entre les signaux électroniques traités par les moyens d'interface et les organes, appropriés à la nature de cet organe dans le même type. Cette variété implique la nécessité de disposer d'une gamme de moyens d'adaptation et d'interface pour réa¬ liser les liaisons, chaque unité de cette gamme dans laquelle ces moyens sont regroupés, se présentant sous La forme d'un boîtier ou module devant être reçu par le plan de pose susdit et être ra ccordé à l'organe. Pour que La maintenance d'une telle liaison soit aisée, il faut que chaque module puisse être facilement séparé du plan de pose et de L 'organe auquel i l est relié. Cette possibi lité, qu est ind spensable, peut être la source de nombreuses erreurs de raccordement. En effet, on sait que Les composants qui constituent les moyens d' interface et d'adaptation sont, dans la liaison entre l 'organe et l 'unité de commande, les éléments qui sont sujets à une fréquence de panne plus élevée, d'autant qu'i ls comportent des dispo¬ sitifs de protection de certains circuits électron ques qui, tels les fusibles, ne remplissent leur fonction que par destruction. Le module de raccordement comporte donc des éléments, soit frag les, soit consommables qui nécessitent son démontage et son remplacement. Or, bien que chaque module soit spécifique à L 'organe qu'i l raccorde à l 'unité de com- mande, i l présente une surface de connexion au plan de pose identique et, dans la majorité des cas, un dispositif de connexion à l 'organe, non distinctif d'un organe à L 'autre puisque pouvant s'agir simplement de deux fi ls. Ainsi, à [ 'occasion d'un remplacement de module réalisé par une main- d'oeuvre d'entretien non spécialisée, du moins dans le domaine des automatismes, i l peut très bien se produire une mise en place de module non adapté à l 'organe concerné conduisant à une mise hors service de L ' nstallation.In addition, within each type there are organs of a different nature. These include two-wire detectors, Three-wire detectors, Contact sensors for transmitting components and for others, receiving components supplied directly from the energy source available at the connection terminals of the installation surface or with separate power supply by a line on which it is necessary to act to transmit the data. It can therefore be understood that if there is an implementation of adaptation means, between the electronic signals processed by the interface means and the members, appropriate to the nature of this member in the same type. This variety implies the need to have a range of adaptation and interface means for realizing the links, each unit of this range in which these means are grouped, being in the form of a box or module to be received by the above-mentioned installation plan and to be connected to the body. For the maintenance of such a connection to be easy, it is necessary that each module can be easily separated from the laying surface and from the member to which it is connected. This possibility, which is essential, can be the source of numerous connection errors. Indeed, we know that The components which constitute the means of interface and adaptation are, in the connection between the body and the control unit, the elements which are subject to a higher frequency of failure, all the more so if they include devices for protecting certain electron circuits which, like fuses, only fulfill their function by destruction. The connection module therefore includes elements, either fragile or consumable, which require its disassembly and replacement. However, although each module is specific to the member that it connects to the control unit, it has an identical connection surface to the installation plane and, in most cases, a connection device to the organ, not distinctive from one organ to the other since it can be simply two sons. Thus, on the occasion of a module replacement carried out by unskilled maintenance labor, at least in the field of automation, it may very well occur that a module is not adapted to the 'organ concerned leading to a decommissioning of the installation.
Le problème à résoudre comporte donc deux exigences. D'une part, i l est nécessaire de pouvoir disposer d'un pLan de pose standard pour faci liter le câblage et per¬ mettre l ' plantat on, dans une même zone de raccordement, de tous les modules différents correspondant à des organes de nature différente situés au voisinage du plan de pose. On notera à cet égard que pour ce qui concerne La première installation (câblage initial) on a affaire à une ma i n-d ' oeuvr compétente avec laquelle Les risques d'erreurs de branche¬ ment sont réduits. D'autre part, il faut diminuer les erreurs de branchement possibles Lors des opérations de maintenance effectuées par une main-d'oeuvre moins qualifiée, afin que le remplacement d'un module ne puisse être possible que par un module identique, c'est-à-dire adapté à L 'organe.The problem to be solved therefore has two requirements. On the one hand, it is necessary to be able to have a standard laying plan to faci liter the wiring and per¬ put the plantat on, in the same connection area, all the different modules corresponding to organs of nature located in the vicinity of the laying plane. It will be noted in this respect that as regards the first installation (initial wiring) we are dealing with a ma i n-of competent work with which the risks of branching errors are reduced. On the other hand, it is necessary to reduce possible connection errors. During maintenance operations carried out by less qualified labor, so that the replacement of a module can only be possible with an identical module, this is ie adapted to the organ.
L'invention entend proposer une solution à ce problème en prévoyant au niveau du module de raccordement des moyens grâce auxquels, Lors d'un premier niveau de main- tenance, une partie seulement du module, celle contenant les éléments ou composants à fréquence de panne statisti¬ quement plus importante, est séparable du support et découvre une surface de connexion tout à fait spécifique de l'organe et qui ne peut recevoir qu'une partie en tout point semblable à celle qui vient d'être déconnectée.The invention intends to propose a solution to this problem by providing at the connection module means by which, during a first level of hand- tenance, only part of the module, that containing the elements or components with a statistically higher failure frequency, is separable from the support and discovers a completely specific connection surface of the member and which can only receive one part in every respect similar to that which has just been disconnected.
Plus précisément, L'invention a pour objet un dispositif de connexion de l'un quelconque d'une pluralité d'organes différents gérés par une unité de commande program- mable, sur un support définissant un plan de pose standard, comportant, rassemblées dans un arrangement prédéterminé unique, des bornes de connexion pour des voies électroniques issues de ladite unité de commande et pour des lignes électri¬ ques d'alimentation issues d'une ou plusieurs sources. Selon une caractéristique importante de l 'in¬ vention, ce dispositif est constitué par un boîtier en deux parties dissociables l'une de l 'autre, chacune d'elles comportant des éléments d'interface et/ou d ' adaptation .propres à l 'organe concerné, l'une de ces parties étant conformée en un connecteur de raccordement de l'organe audit boîtier, tandis que ledit connecteur présente une première surface qui, Lorsqu'il est associé à l 'autre partie, constitue une portion au moins d'une surface de connexion unique du boîtier apte à être reçue par Ledit plan de pose, et une seconde surface qui, lorsqu'i l est dissocié de ladite autre partie, constitue une portion au moins d'une surface de connexion apte à recevoi r ladite autre partie seule et spécifique de l 'organe à connecter.More specifically, the subject of the invention is a device for connecting any one of a plurality of different organs managed by a programmable control unit, on a support defining a standard laying plane, comprising, gathered in a single predetermined arrangement, connection terminals for electronic channels from said control unit and for electrical supply lines from one or more sources. According to an important characteristic of the in¬ vention, this device consists of a housing in two parts separable from each other, each of them comprising interface and / or adaptation elements. member concerned, one of these parts being shaped as a connector for connecting the member to said housing, while said connector has a first surface which, when associated with the other part, constitutes at least one portion of a single connection surface of the housing capable of being received by said laying plane, and a second surface which, when it is dissociated from said other part, constitutes at least a portion of a connection surface capable of receiving r said other single and specific part of the member to be connected.
De manière avantageuse, le connecteur susdit est équipé de moyens pour sa fixation audit support.Advantageously, the aforementioned connector is equipped with means for fixing it to said support.
Dans un premier mode de réalisation, Les première et seconde surfaces du connecteur sont parallèles.In a first embodiment, the first and second surfaces of the connector are parallel.
Dans un second mode de réalisation, ces sur¬ faces sont perpendiculaires. Enfin, la seconde surface susdite du connecteur possède des moyens de détrompage spécifiques de L 'organe à raccorder aptes à coopérer avec des moyens correspondants prévus sur ladite autre partie du boîtier.In a second embodiment, these sur¬ faces are perpendicular. Finally, the aforesaid second surface of the connector has specific keying means for the member to be connected capable of cooperating with corresponding means provided on said other part of the housing.
L'invention sera mieux comprise au cours de la description donnée ci-après à titre d'exemple purement indi¬ catif et- non limitatif, qui permettra d'en dégager les avan¬ tages et les caractéristiques secondaires.The invention will be better understood during the description given below by way of purely indicative and non-limiting example, which will make it possible to identify the advantages and the secondary characteristics thereof.

En se reportant tout d'abord aux figures 1, 1A et 1B, on voit un support 1 définissant un plan de pose 2, comportant un arrangement déterminé de bornes 3 et 4 de connexion. Certaines 3 de ces bornes sont reliées à des voies électroniques issues de l 'unité de commande programmable non représentée, qui parviennent au support 1 dans le guide- câbles 5. Les bornes 4 sont, quant à elles, des moyens de connexion pour le dispositif de raccordement, à des lignes d'ali entation en énergie électrique, conduites jusqu'au support 1 également par le guide-câbles 5. Le support peut comporter une pluralité d'arrangements de bornes 3 et 4 côte à côte, qui sont pour chacun d'eux, autant de dérivations des voies électroniques et des Lignes d'alimentation susdites, qui peuvent traverser le support 1 et se poursuivre au- delà de celui-ci pour desservir d'autres supports. L'arran¬ gement de bornes 3 et 4 est unique dans sa configuration et se repète sur le support 1 et sur chacun des supports que l 'installation met en oeuvre, autant de fois qu'il y a d'organes à raccorder. La portion de surface pLane du support 1 qui porte chaque arrangement constitue ce qui sera appelé par la suite le plan de pose standard.Referring first to Figures 1, 1A and 1B, we see a support 1 defining a laying plane 2, comprising a determined arrangement of connection terminals 3 and 4. Some 3 of these terminals are connected to electronic channels coming from the programmable control unit not shown, which reach the support 1 in the cable guide 5. The terminals 4 are, for their part, connection means for the device of connection, to power supply lines, led to the support 1 also by the cable guide 5. The support can comprise a plurality of terminal arrangements 3 and 4 side by side, which are for each from them, as many derivations of the aforementioned electronic channels and supply lines, which can cross the support 1 and continue beyond beyond this to serve other media. The arrangement of terminals 3 and 4 is unique in its configuration and is repeated on the support 1 and on each of the supports that the installation implements, as many times as there are members to be connected. The plane surface portion of the support 1 which carries each arrangement constitutes what will be called hereinafter the standard laying plane.
Le dispositif de connexion d'un organe à ce plan de pose standard est constitué par un boîtier 6 en deux parties 6a_ et 6tj qui contient des moyens assurant une fonc¬ tion d'interface et d'adaptation entre Les signaux de type nformationnel exploi tabl es par l 'unité de commande et qui sont présents au niveau des bornes 3 et les signaux d'un niveau de puissance généralement plus élevé qui, eux, sont exploitables par L 'organe raccordé au boîtier 6 par un câble de l aison 7.The device for connecting an organ to this standard laying plane is constituted by a box 6 in two parts 6a_ and 6tj which contains means ensuring an interface and adaptation function between signals of informational type tabl es by the control unit and which are present at the terminals 3 and the signals of a generally higher power level which, for their part, can be exploited by the member connected to the housing 6 by a connection cable 7.
Les deux parties 6a^ et 6J3 sont séparables L 'un de l 'autre, la partie 6^ étant conformée en un connecteur par lequel le boîtier 6 est relié au câble 7. Lorsque ces deux parties 6a_ et 6t> sont associées, comme le montre la figure 1A, Le boîtier 6 qu'elles constituent, présente une première surface de connexion 8 dont une portion est consti- tîée par une première surface 8a_ du connecteur 6b^, pourvues de bornes 9 et 10 ici mâles, aptesà être reçues par Le plan de pose standard 2, comme le montre la flèche A. Dans le cas de La figure , les bornes 9 coopèrent avec les bornes 3 du support 1 pour assurer La liaison des voies électroniques, tandis que les bornes 10 coopèrent avec les bornes 4 pour assurer La liaison entre des moyens d'adaptation et de l 'orga ne avec l 'alimentation en niveau d'énergie souhaité. On voit sur cette figure que les bornes de liaison aux lignes d'ali¬ mentation sont toutes portées par le connecteur 6J3 du boîtier. Cette disposition n'est pas impérative et on verra en regard de certaines des figures suivantes qu'i l peut exister des dispositions différentes. Au moment de la construction de la machine et de son câblage, le boîtier 6 est disponible dans sa confi¬ guration de la figure 1A. Le cableur procède au raccordement du câble 7, soit au connecteur 6b_ par des moyene de connexion prévus à cet effet et qui seront décrits et représentés ci- après, si le câble 7 fait partie de l 'organe à connecter et y est raccordé de fabrication, soit à l 'organe si Le boîtier 6 est disponible avec son câble 7 qui y est raccordé de manière indémontable dès la fabrication, l'organe n'étant pas équipé de fabrication d'un câble de raccordement, soit enfin, par les deux extrémités du câble 7, au raccordement de ce dernier à l 'organe et au connecteur 6b_. Cette liaison étant réalisée, il procède alors à l 'enfichage de l 'ensemble sur te plan de pose. Plus précisément, le câbleur sépare les deux parties 6a_ et 6b pour d'abord connecter la partie 6b et la mainteni r fixée au support 1 par la vis 11 coopérant avec l'orifice taraudé 12. Puis il enfiche la partie 6a_ sur l 'en¬ semble et La fixe au moyen de La vis 13 coopérant avec l'ori- fice taraudé 14. Cette disposition est avantageuse pour assurer la sécurité des connexions mais peut ne pas être indispensable pour certaines applications dans lesquelles seules les forces de friction entre les bornes mâles et femelles suffît à assurer le maintien de l 'ensemble. Dans ce cas on pourra prévoir un engagement des bornes 10 et 4 plus serré que toutes les autres bornes pour que le connecteur 6b_ reste en place sur le plan de pose si l 'on ne retire que la partie 6a_ du boîtier.The two parts 6a ^ and 6J3 are separable from each other, the part 6 ^ being shaped as a connector by which the housing 6 is connected to the cable 7. When these two parts 6a_ and 6t> are associated, as the shows FIG. 1A, the box 6 which they constitute, has a first connection surface 8, a portion of which is constituted by a first surface 8a_ of the connector 6b ^ , provided with male terminals 9 and 10 here, capable of being received by The standard installation plane 2, as shown by arrow A. In the case of the figure, the terminals 9 cooperate with the terminals 3 of the support 1 to ensure the connection of the electronic channels, while the terminals 10 cooperate with the terminals 4 to ensure the connection between adaptation means and the organ with the supply of the desired energy level. It can be seen in this figure that the connection terminals to the supply lines are all carried by the connector 6J3 of the housing. This provision is not imperative and it will be seen with respect to some of the following figures that there may be different provisions. At the time of construction of the machine and its wiring, the housing 6 is available in its configuration of FIG. 1A. The cabler proceeds to the connection of the cable 7, that is to the connector 6b_ by connection means provided for this purpose and which will be described and shown below, if the cable 7 is part of the member to be connected and is connected to it during manufacture. , either to the member if the box 6 is available with its cable 7 which is connected therein in a non-removable manner from manufacture, the member not being equipped with the manufacture of a connection cable, or finally, by the two ends of the cable 7, at the connection of the latter to the member and to the connector 6b_. This connection being made, it then plugs the assembly onto the laying surface. More precisely, the cable operator separates the two parts 6a_ and 6b to first connect the part 6b and hold it fixed to the support 1 by the screw 11 cooperating with the threaded orifice 12. Then he plugs the part 6a_ onto the ¬ seems and fixes it by means of the screw 13 cooperating with the tapped hole 14. This arrangement is advantageous for ensuring the security of the connections but may not be essential for certain applications in which only the friction forces between the terminals males and females is sufficient to ensure the maintenance of the whole. In this case, it will be possible to provide a tighter engagement of the terminals 10 and 4 than all the other terminals so that the connector 6b_ remains in place on the laying surface if only part 6a_ of the housing is removed.
Le câblage étant réalisé, pour tous les orga- nés, avec Leur boîtier ou module 6 spécifique, comme décrit ci-dessus, le dispositif de connexion est en service comme représenté sur la figure 1. L'exploitant de L 'installation, détectant une défai llance de l 'un des organes raccordé ou de l'un des modules , ou désirant procéder à une modification de L' installation, est amené à intervenir sur le dispositif de connexion. Pour ce faire, il procède au démontage de La partie 6a_ du module 6 en dévissant La vis 13 qui constitue en même temps extracteur des broches enfichées et peut alors retirer cette partie, comme l 'indique La flèche B de la figure 1B. IL découvre alors une seconde surface de connexion constituée sur la figure 1B par une portion du plan de pose 2 et une seconde surface 15 du connecteur. Cette seconde surface de connexion est alors, contrairement à la première surface 8 susdite qui est identique quel que soit le module 6, spécifique de l'organe à raccorder, et ne peut recevoir qu'une partie 6a_ du module adaptée à l'organe en cause. Les moyens qui confèrent sa spécificité à cette s-urface de connexion sont portés par ladite surface 15 du connecteur qui coopèrent avec des moyens correspondants prévus sur La partie 6 de module. Ces moyens peuvent être des organes de détro page réalisés sous la forme d'une pluralité de picots 16 reçus dans des logements 17 de La partie 6a, dont la forme et la disposition sur la surface 15 varient d'un organe à l'autre donc d'une partie 6 à l 'autre. Ils pourraient être constitués par une disposition et une forme de bornes 18,19 de conne¬ xion de la partie 6a_ au connecteur 6b différentes pour chaque module 6 de la gamme existante.The wiring being carried out, for all the organs, with their specific box or module 6, as described above, the connection device is in service as shown in FIG. 1. The operator of the installation, detecting a failure of one of the connected components or one of the modules, or wishing to modify the installation, is called upon to intervene on the connection. To do this, he disassembles part 6a_ of module 6 by unscrewing screw 13 which at the same time constitutes the extractor of the plugged pins and can then remove this part, as indicated by arrow B in FIG. 1B. IL then discovers a second connection surface formed in FIG. 1B by a portion of the laying plane 2 and a second surface 15 of the connector. This second connection surface is then, unlike the aforementioned first surface 8 which is identical whatever the module 6, specific to the member to be connected, and can only receive a part 6a of the module adapted to the member in cause. The means which confer its specificity to this connection s-urface are carried by said surface 15 of the connector which cooperate with corresponding means provided on part 6 of the module. These means may be detro page members produced in the form of a plurality of pins 16 received in housings 17 of part 6a, the shape and arrangement of which on the surface 15 vary from one member to another therefore from part 6 to another. They could be constituted by an arrangement and a form of terminals 18, 19 for connection of the part 6 a to the connector 6 b different for each module 6 of the existing range.
Comme dans la plupart des cas, la panne consiste en une défaillance des composants (ou de l'un d'eux) contenus dans la partie 6a du module 6, La réparation est réalisée par l 'échange standard de cette partie qui peut alors être réalisé sans risque d'erreur par une main-d'oeuvre non qualifiée. Si en revanche, ce premier niveau d'intervention n'est pas suffisant, soit par ce que c'est l'organe lui-même qui est défaillant, ou parce qu'i l s'agit d'une modification " de l ' installation, l'exploitant peut procéder au démontage du connecteur 6b, voire à la déconnection du câble 7 de ce con¬ necteur et/ou de l 'organe. Dans ce cas, les risques d'erreurs au remontage peuvent être plus importants mais à un tel niveau d ' i ntervent ion, on a recours à un personnel plus qualifié, dont La compétence est un facteur de diminution de ce ri sque .As in most cases, the failure consists of a failure of the components (or one of them) contained in part 6a of module 6, The repair is carried out by the standard exchange of this part which can then be carried out without risk of error by unskilled labor. If, on the other hand, this first level of intervention is not sufficient, either because it is the organ itself which is faulty, or because it is a modification " of the installation, the operator can disassemble the connector 6b, or even disconnect the cable 7 from this connector and / or the body, in which case the risks of reassembly errors may be greater, but at such a high level of intervention, more staff are used qualified, whose competence is a factor in reducing this risk.
On voit que les dispositions de l' invention permettent de laisser subsister, au niveau du raccordement séparable de chaque organe à la ligne de circulation des informations qu' il échange avec L'unité centrale de commande un souvenir ou une mémoire de la nature de L'organe raccordé qui interdit toute erreur de branchement pour des interven¬ tions de premier niveau, consistant à remplacer des parties défai llantes du dispositif de raccordement qui, bien que spécifiques, possèdent toutes à première vue la même apparenIt can be seen that the provisions of the invention make it possible to leave at the level of the separable connection of each member to the line for circulating information which it exchanges with the central control unit a memory or a memory of the nature of L 'connected body which prohibits any connection error for first level interventions, consisting in replacing defective parts of the connection device which, although specific, all have at first sight the same appearance
Sur la figure 2 on a représenté une variante de réalisation des figures précédentes dans Laquelle le boîtier ou module 6 est inchangé et comporte une partie 6a et un connecteur 6b_. En revanche, le support du plan de pose est constitué par un boîtier de dérivation 20 des lignes électroniques ou d'alimentation contenues dans Le guide- c§bles 5 auquel peuvent être associés une pluralité d'élément modulaires 21 portant chacun le plan de pose 2 standard apte à recevoir le module 6. Chaque élément 21 comporte deux faces parallèles telles que 21a_ par lesquelles ils sont associés entre eux et au boîtier 20 pour assurer les condi¬ tions nécessaires à La continuité de la déri ation des lignes électriques et électroniques, les faces 21a_ étant perpendiculaires au plan de pose 2. Des moyens de fixation des modules entre eux, tels que des vis 22 peuvent être prévus pour assurer le maintien de l'ensemble. L'intérêt de cette variante réside dans la possibilité qu'elle offre d'ajuster exactement le nombre de plans de pose 2 au nombre des organes à raccorder. Le câblage initial et la maintenanc sont assurés de la même manière que celle précédemment décrite.In Figure 2 there is shown an alternative embodiment of the previous figures in which the housing or module 6 is unchanged and comprises a part 6a and a connector 6b_. On the other hand, the support of the laying plane consists of a junction box 20 for the electronic or supply lines contained in the cable guide 5 to which a plurality of modular elements 21 can each be associated, each carrying the laying plane 2 standard capable of receiving the module 6. Each element 21 has two parallel faces such as 21a_ by which they are associated with one another and with the housing 20 to ensure the conditions necessary for the continuity of the deviation of the electrical and electronic lines, the faces 21a_ being perpendicular to the laying plane 2. Means for fixing the modules together, such as screws 22 may be provided to ensure the maintenance of the assembly. The advantage of this variant lies in the possibility that it offers of exactly adjusting the number of laying planes 2 to the number of members to be connected. The initial wiring and maintenance are carried out in the same way as that previously described.
Sur la figure 3, la variante représentée conce ne le connecteur. Alors que dans les figures précédentes, les deux surfaces 8a et 15 du connecteur 6b sont parallèles, "dans cette figure le connecteur 36 présente deux surfaces de connexion 36a_ et 36Ja perpendiculaires. Le support du plan de pose standard est constitué par un boîtier de dérivation 30 semblable au boîtier 20 de la figure 2 présentant sur L 'un et/ou l 'autre de ses chants 30a, 30b une surface de connexion constituant pLan de pose standard. Le boîtier de raccordement est, comme dans les figures précédentes, cons¬ titué par deux parties séparables, à savoir Le connecteur 36 et une autre partie 37. La mise en place du boîtier complet (les deux parties associées) est réalisée sur Le plan de pose par la première surface 36a du connecteur apte à être reçue par le plan de pose. Le connecteur porte, contrairemen aux figures précédentes, La totalité de la surface de con¬ nection du module au plan de pose (surface 36a_) . La seconde surface de connexion 36b_ portée par le connecteur 36 est perpendiculaire à La surface 36a_ et reçoit la partie 37. A cet effet, elle comporte des moyens de détrompage (picots 38) qui jouent le- même rôle que ceux décrits en regard des • figures précédentes et qui peuvent souffrir les mêmes variantes. On voit que dans ce cas, contrairement aux figu¬ res 1 à 1B dans Lesquelles La surface 15 ne constitue qu'une portion de La seconde surface de connexion pour la partie 6a_ du module, la surface 36JD constitue la totalité de cette surface. Le connecteur 36 comporte enfin une troisième sur- face 36 parallèle à la surface 36a^ qui est une répétition du plan de pose standard et qui permet d'associer les con¬ necteurs 36 les uns aux autres comme Les éléments modulaires du support de la figure 2 s'associent entre eux. Les élément de fixation tels que Les vis 31 et 33 permettent de fixer chacun des connecteurs au précédent, donc au support 30In Figure 3, the variant shown conce ne the connector. While in the previous figures, the two surfaces 8a and 15 of the connector 6b are parallel, "in this figure, the connector 36 has two perpendicular connection surfaces 36a_ and 36Ja. The support of the standard laying surface is constituted by a junction box 30 similar to the box 20 of FIG. 2 having on one and / or the Another of its edges 30a, 30b is a connection surface constituting a standard installation plan.The connection box is, as in the previous figures, made up of two separable parts, namely the connector 36 and another part 37. in place of the complete housing (the two associated parts) is produced on the installation plane by the first surface 36a of the connector capable of being received by the installation plane. The connector carries, contrary to the previous figures, The entire surface of connection of the module to the laying plane (surface 36a_) The second connection surface 36b_ carried by the connector 36 is perpendicular to the surface 36a_ and receives part 37. To this end, it co has keying means (pins 38) which play the same role as those described with reference to the previous figures and which can suffer the same variants. It can be seen that in this case, contrary to FIGS 1 to 1B in which the surface 15 constitutes only a portion of the second connection surface for the part 6a_ of the module, the surface 36JD constitutes the whole of this surface. The connector 36 finally comprises a third surface 36 parallel to the surface 36a ^ which is a repetition of the standard installation plane and which makes it possible to associate the connectors 36 with one another as The modular elements of the support of the figure 2 associate with each other. The fixing elements such as the screws 31 and 33 allow each of the connectors to be fixed to the previous one, therefore to the support 30
(vis 31) et chaque partie 37 à son connecteur particulier (vis 33) .(screw 31) and each part 37 to its particular connector (screw 33).
On voit que, pour un premier niveau d'interven tion, on peut retirer la partie de module 37 en découvrant une surface de connexion spécifique à sa nature, donc à l 'organe raccordé (surface 36b_) . Un second niveau d'inter¬ vention nécessite le débranchement du câble 7 du connecteur 36, débranchement possible grâce, soit à une connexion ins¬ tantanée par enfichage de l'extrémité 7a du câble sur l'une ou l 'autre des faces d'extrémité du connecteur 36, soit à une connexion par bornes vissées disposées à ces extrémités. Le dépi lage des connecteurs relève d'un troisième niveau de maintenance, car comme on le verra en regard des figures suivantes, les composantes internes du connecteur se rédui- sent à des lignes de transmission et des bornes de connexion très peu sujettes à détérioration, ne nécessitant pratique¬ ment aucune maintenance. Cette possibilité d'intervention doit quand même exister pour rendre possible des modificatio de l 'installation au cours de son exploitation. Les figures 4A, 4B et 4C illustrent schémati- quement trois exemples de structure interne du connecteur selon l ' invention dans sa forme de réalisation des figures 1, 1A et- 1B.It can be seen that, for a first level of intervention, the module part 37 can be removed by discovering a connection surface specific to its nature, therefore to the connected member (surface 36b_). A second level of intervention requires the disconnection of the cable 7 from the connector 36, disconnection possible thanks to either an instantaneous connection by plugging the end 7a of the cable onto one or other of the faces of end of connector 36, that is to say a connection by screwed terminals arranged at these ends. The screening of the connectors is a third level of maintenance, because as we will see with regard to the following figures, the internal components of the connector are reduced to transmission lines and connection terminals very little subject to deterioration, practically requiring no maintenance. This possibility of intervention must still exist to make it possible to modify the installation during its operation. FIGS. 4A, 4B and 4C schematically illustrate three examples of the internal structure of the connector according to the invention in its embodiment of FIGS. 1, 1A and -1B.
On notera tout d'abord que le plan de pose 2 porté par le support 1, présente un arrangement de bornes de connexion légèrement différent de celui représenté aux figures 1, 1A et 1B. C'est ainsi que les bornes du type 4 de la figure 1B peuvent être en nombre plus important, en étant partiellement dédoublées par exemple, pour accueillir soit un module 40 (figure 4A), soit un module 50 (figure 4B) . On voit en effet que le module 40, comportant une partie 40a_ et un connecteur 40b, possède toutes ses bornes de connexion portées par la partie 40a_, et notamment Les bornes 41 qui relient le module aux lignes d'alimentation. Dans ce cas, la face 48a_ du connecteur 40b_ est reçue par le plan de pose sans aucune connexion électrique. L'alimentation de l 'organe en énergie par le câble 7 s'effectue donc au travers de La partie 40a du module et du connecteur 40fc>. La commande de l fermeture ou de l 'ouverture de cette ligne, si l 'organe est un organe récepteur, ou la lecture de l 'état de cette Ligne, si l'organe est un émetteur, est réalisée par les moyens électroniques d'interface et d'adaptation contenus dans La partie 40a_. Le connecteur 40J3 possède, bien entendu, Les mêmes fonctions de "mémoire" sur Le plan de pose de La nature de l 'organe, que le connecteur 6b_ des figures 1, 1A 1B, du fait que sa seconde surface 45 présente les mêmes moyens de détrompag.e que ceux décrits précédemment, et qu'i l reste attaché au plan de pose par la vis 42 lorsqu'on reti la partie 40a_. Du point de vue électrique, le connecteur n'assure qu'une fonction de liaison par les conducteurs internes 43 et 44 qu'il comporte, lesquels aboutissent à d bornes à vis 46 et 47 permettant Le raccordement démontabl du câble 7.Note first of all that the laying plane 2 carried by the support 1, has an arrangement of connection terminals slightly different from that shown in Figures 1, 1A and 1B. This is how the type 4 terminals of FIG. 1B can be in greater number, being partially split for example, to accommodate either a module 40 (FIG. 4A), or a module 50 (FIG. 4B). It can be seen that the module 40, comprising a part 40a_ and a connector 40b, has all of its connection terminals carried by the part 40a_, and in particular the terminals 41 which connect the module to the supply lines. In this case, the face 48a_ of the connector 40b_ is received by the installation plane without any electrical connection. The power supply to the member by the cable 7 is therefore carried out through the part 40a of the module and of the connector 40fc>. The command to close or open this line, if the organ is a receiving organ, or to read the state of this Line, if the organ is an emitter, is carried out by the electronic interface and adaptation means contained in Part 40a_. The connector 40J3 has, of course, the same functions of "memory" on the laying plane of the nature of the organ, as the connector 6b_ of Figures 1, 1A 1B, because its second surface 45 has the same means coded as those described above, and that it remains attached to the installation plane by the screw 42 when the part 40a_ is removed. From the electrical point of view, the connector only performs a connection function through the internal conductors 43 and 44 which it comprises, which lead to d screw terminals 46 and 47 allowing the detachable connection of the cable 7.
Sur la figure 4B, le module 50 est connecté lignes d'alimentation en énergie par des bornes 10 identi¬ ques à celles de La figure 1B, donc au travers du connecte 50b^. Ainsi, dans ce cas de figure, La ligne d'alimentation est refermée sur la source au travers du connecteur 50b_, con rai rement à La figure précédente où elle était refermé sur la source en dehors de ce connecteur. Ce connecteur 50b comporte également des bornes à vis 56 et 57, pour le racco dement du câble 7.In FIG. 4B, the module 50 is connected to power supply lines by terminals 10 identical to those of FIG. 1B, therefore through the connects 50b ^ . Thus, in this case, the supply line is closed on the source through the connector 50b_, con rai rement to the previous figure where it was closed on the source outside this connector. This connector 50b also includes screw terminals 56 and 57, for the connection of cable 7.
Enfin sur la figure 4C, on a représente un module 60 dont le connecteur 60JD présente des surfaces 68a_ 65 identiques à celles 58a_ et 55 du connecteur 50b_,mais adapté à recevoir un détecteur particulier dit détecteur 3 fi ls. A cet effet, i l comporte trois bornes à vis 66, 67 69 pour le raccordement des trois fi ls que comporte Le câbl 7. Le connecteur 60b assure donc Les liaisons électriques particulières qu'exige un tel détecteur.Finally in FIG. 4C, a module 60 is shown, the connector 60JD of which has surfaces 68a_ 65 identical to those 58a_ and 55 of the connector 50b_, but adapted to receive a particular detector known as a 3-wire detector. For this purpose, it has three screw terminals 66, 67 69 for the connection of the three wires which the cable 7. The connector 60b therefore provides the particular electrical connections required by such a detector.
Les modules du type 40 et 50 peuvent être uti lisés pour raccorder des organes émetteurs tels que des capteurs à contact ou des détecteurs deux fils ou des organ récepteurs dont l'alimentation est réalisée directement par la ligne commandée au travers du module ou de manière sépar la ligne commandée étant alors une ligne d'alimentation de l'organe interrupteur (relais) de la ligne séparée. Mais il est important de noter que si à l 'état assemblé deux modules de même type (40 ou 50) sont semblables voire identiques, chaque module de chaque type est différent des autres par le fait que sa partie 40a_ ou 50a_ comporte des composants différents selon l'organe auquel il est relié et que Les moyens de détrompage prévus au niveau des faces 45 et 55 sont différents d'un module destiné à un organe à un module destin a un autre organe. En d'autres termes, un module 50 destiné à raccorder un capteur à contact peut, ses parties 50a_ et 50b réunies, présenter le même aspect qu'un module 50 destiné à raccorder un organe récepteur du type contacteur.. En revanche, La partie 50a_ du module destiné au capteur n.e peut pas être associée à un connecteur 50b préalablement reli à un contacteur du fait que La surface de connexion de cette partie au plan de pose équipé du connecteur est différente de celle qu'offre le connecteur relié au contacteur. La seule possibilité d'erreur reste le raccordement au moment du câblage, d'un module destiné au capteur, par exemple à un contacteur. Ce problème reste cependant maîtrisé car le personnel de câblage est très spécialisé et très qualifié. De plus on aura prévu-, par ailleurs, des repères d'identifica¬ tion des modules permettant à ce personnel de les affecter correctemen .The modules of type 40 and 50 can be used to connect transmitting devices such as contact sensors or two-wire detectors or receiving devices which are supplied directly by the line controlled through the module or separately the controlled line then being a supply line for the switch member (relay) of the separate line. But it is important to note that if in the assembled state two modules of the same type (40 or 50) are similar or identical, each module of each type is different from the others by the fact that its part 40a_ or 50a_ has different components according to the member to which it is connected and that the keying means provided at the faces 45 and 55 are different from a module intended for one member to a module intended for another member. In other words, a module 50 intended to connect a contact sensor can, its parts 50a_ and 50b combined, have the same appearance as a module 50 intended to connect a receiving member of the contactor type. On the other hand, the part 50a_ of the module intended for the sensor cannot be associated with a connector 50b previously connected to a contactor because the connection surface of this part to the installation surface equipped with the connector is different from that offered by the connector connected to the contactor. The only possibility of error remains the connection at the time of wiring, of a module intended for the sensor, for example with a contactor. However, this problem remains under control because the wiring personnel are very specialized and highly qualified. In addition, provision will have been made for identification marks of the modules allowing this staff to assign them correctly.
