Description

Dispositif pour affecter une adresse de consigne codée à un circuit électronique de reconnaissance d'adresses, et repérer ce circuit. Device for assigning a coded setpoint address to an electronic address recognition circuit, and locating this circuit.
Dans une liaison entre une unité centrale programmable de commande d'une installation industrielle et les organes de cette installation qui échangent des informations et des ordres dans une séquence déterminée par le programme de l' unité de commande, Les données exploitées par l'unité de commande et par chacun des organes nécessitent un traitement, d'une part pour transformer une grandeur physique en un signal électronique exploitable par L 'unité de commande et un signal électronique en une grandeur physique exploitable par L 'organe en cause,et d'autre part, pour adresser le signal électronique afin que l'unité de commande puisse interroger un organe d'entrée (capteur ou détecteur) qu'elle connaît par son adresse ou transmettre un signal à l 'adresse de l* organe qui doit Le recevoir. Ce traitement est assuré par des moyens d' interface é l ect roni ques coopérant avec des moyens d'adaptation prévus sur chaque ligne de liaison d'un organe à L 'unité de commande.In a connection between a programmable central control unit of an industrial installation and the organs of this installation which exchange information and orders in a sequence determined by the program of the control unit, The data used by the control unit control and by each of the organs require processing, on the one hand to transform a physical quantity into an electronic signal exploitable by the control unit and an electronic signal into a physical quantity exploitable by the organ in question, and on the other part, to send the electronic signal so that the control unit can interrogate an input device (sensor or detector) that it knows by its address or transmit a signal to the address of the device that is to receive it. This processing is ensured by electronic interface means cooperating with adaptation means provided on each line connecting a member to the control unit.
Pour ce qui concerne la reconnaissance des adresses. Les moyens électron ques d'interface possèdent, de manière connue un circuit électronique de comparaison d'adresses, qui reçoit en entrée toutes les informations codées (donnée plus adresse ou adresse et signal d'interrogation) émises par L 'unité de commande pour comparer chacune d'elle avec une adresse en consigne correspondant à un organe particulier et délivrer, en réponse à la reconnaissance de l 'identité de l 'adresse en consigne avec l 'une des adresses émises par l'unité de commande, un ordre de transmission de la donnée, soit en direc¬ tion d'un organe receveur, soit en direction de l 'unité pro¬ grammable, si l'organe est émetteur. Généralement, l 'adresse en consigne et les adresses à comparer à cette consigne sont codées sous la forme d'un état de tension (0 ou 1) de chacun d'une pluralité de conducteurs examinés dans un ordre déterminé. Ainsi, si le nombre de ces conducteurs est huit, le nombre d'états différents de Leur combinaison est 256. Affecter une adresse à un circuit électro- nique de comparaison d'adresses (ou encoder ce circuit) consiste donc à établir des connexions entre certains des conducteurs de la pluralité des conducteurs du circuit portant la valeur de consigne avec une source de potentiel et d'isoler les autres conduc- teurs de cette source, pour les maintenir par exemple au potentiel opposé.Regarding the recognition of addresses. The electronic interface means have, in a known manner an electronic address comparison circuit, which receives as input all the coded information (data plus address or address and interrogation signal) emitted by the control unit for comparing each of them with a setpoint address corresponding to a particular body and issue, in response to recognition of the identity of the setpoint address with one of the addresses sent by the control unit, a transmission order of the data, either in the direction of a receiving organ, or in the direction of the programmable unit, if the organ is transmitting. Generally, the address setpoint and the addresses to be compared with this setpoint are coded in the form of a voltage state (0 or 1) of each of a plurality of conductors examined in a determined order. Thus, if the number of these conductors is eight, the number of states different from their combination is 256. Assign an address to an electro- The comparison of addresses (or encoding this circuit) consists therefore of establishing connections between some of the conductors of the plurality of conductors of the circuit carrying the set value with a source of potential and of isolating the other conductors from this. source, to maintain them for example at the opposite potential.
Il existe plusieurs moyens pour réaliser ces connexions. On citera pour mémoire des m cro-interrupteurs installés sur chacun des conducteurs et qui ouvrent ou ferment une liaison de ceux-ci avec un conducteur issu d'une source de potentiel. On mentionnera également la roue codeuse qui permet, par un f rotteur radial conducteur, relié à une source de potentiel, d'établir un contact entre cette source et des zones conductrices portées par un circuit imprimé et réalisées sous forme de secteurs de couronne concentr ques dont le nombre et La disposition diffèrent d'un secteur à l'autre, le nombre de combinaisons possible dépendant du nombre de pistes concentr ques et pour un nombre donné, du nombre de secteurs adjacents susceptibles d'être balayés par le frotteur solida re en rotation de La roue.There are several ways to make these connections. As a reminder, mention will be made of micro-switches installed on each of the conductors and which open or close a connection of these with a conductor originating from a source of potential. Mention will also be made of the coding wheel which makes it possible, by a conductive radial shoe, connected to a source of potential, to establish contact between this source and conductive areas carried by a printed circuit and produced in the form of concentrated crown sectors. whose number and arrangement differ from one sector to another, the number of possible combinations depending on the number of concentrated tracks and for a given number, on the number of adjacent sectors likely to be swept by the solida re wiper Wheel rotation.
Dans Le cas particulier des automates program¬ mables, l 'adresse de consigne correspond à L ' dentification codée de La position de la carte d'entrées/sorties par rapport aux autres cartes et de la position de la borne de raccorde- ment de L 'organe dans ladite carte. C'est au moment de la construction de La carte que les moyens logiques sont encodés en fonction de la Localisation des bornes auxquelles ils sont connectés, la carte étant encodée ensuite en fonction de son rang, quelquefois par les moyens de micro-interrupteurs ou de roue codeuse décrits ci-dessus. Il peut également exister un dispositif de détrompage mécanique associé à l 'encodage de La carte qui interdit de placer cette dernière à un rang qui ne correspond pas à celui pour lequel elle a été encodée. Certains systèmes de raccordement d'un organe à une unité de commande programmable proposent ou proposeront dans un avenir proche, des moyens permettant de s'aff ranchir des cartes d'entrée/sortie, les moyens d ' i nterfaçage élec¬ troniques et les moyens d'adaptation étant contenus alors dans des boîtiers pouvant être implantés de manière échan- geable en n'importe quel endroit d'un conducteur de circula¬ tion des informations codées issu de l'automate et qui circu¬ lera au voisinage des organes à desservir. Il restera cepen- dant la nécessité d'encoder ces moyens électroniques pour pouvoi r sélectionner et dériver la donnée destinée à l'organe ou La demande d'information émise par L'automate. Cet enco¬ dage devra alors être réalisable de manière simple, la réfé¬ rence du code n'étant plus géographique (position de bornes et de cartes) mais uniquement l 'organe lui-même auquel un repère sera affecté à priori dès La conception de La machine. Les dispositifs connus et rappelés ci-dessus ne pourront plus convenir par manque d'un moyen associant de manière certaine un code exploitable par l 'automate et un repère identique à celui porté par l 'organe et reconnaissa- ble par un opérateur, donc dans une forme alphanumér que. Ce pourrait être à la rigueur possible avec une roue codeuse si Les repères nécessaires sont en nombre très limité. Or, dans La pratique, c'est plusieurs cen taines d'organes qu'i l convient de relier à un automate programmable et la mise en oeuvre de plusieurs roues codeuses deviendrait incompatible avec les encombrements réduits que posséderont les dispositif de raccordement à boîtiers.In the particular case of programmable automatons, the setpoint address corresponds to the coded dentification of the position of the input / output card relative to the other cards and of the position of the connection terminal of L 'organ in said map. It is at the time of the construction of the card that the logical means are encoded according to the location of the terminals to which they are connected, the card then being encoded according to its rank, sometimes by means of microswitches or encoder wheel described above. There may also be a mechanical keying device associated with the encoding of the card which prohibits placing it in a rank which does not correspond to that for which it was encoded. Certain systems for connecting an organ to a programmable control unit offer or will offer in the near future, means making it possible to get rid of the input / output cards, the electronic interfacing means and the adaptation means then being contained in housings which can be installed exchangeably in any place of a conductor for circulating coded information coming from the automaton and which will circulate in the vicinity of the members to be served. There will however remain the need to encode these electronic means in order to select and derive the data intended for the organ or the request for information sent by the automaton. This encoding must then be achievable in a simple manner, the reference of the code no longer being geographic (position of terminals and maps) but only the body itself to which a reference will be assigned a priori from the design of The machine. The known and recalled devices above will no longer be suitable for lack of a means associating in a certain manner a code usable by the automaton and a reference identical to that carried by the member and recognizable by an operator, therefore in an alphanumeric form. It could be strictly possible with a coding wheel if the necessary benchmarks are very limited. However, in practice, it is several hundred organs that should be connected to a programmable controller and the implementation of several coding wheels would become incompatible with the small dimensions which the connection devices with housings will have.
C'est dans ce contexte que s' inscrit l'invention qui entend proposer un dispositif d'encodage de mise en oeuvr simple et sûre permettant la suppression de toute erreur de raccordement tout en offrant tant au constructeur qu'à l 'uti¬ lisateur la possibi lité permanente de faire correspondre l 'organe et son dispositif de raccordement à l'unité centraleIt is in this context that the invention is inscribed, which intends to propose a simple and safe implementation encoding device allowing the elimination of any connection error while offering both to the manufacturer and to the user. the permanent possibility of matching the unit and its connection device to the central unit
A cet effet, l 'invention a donc pour objet un dispositif pour l 'encodage d'un circuit logique de communica- tion décentralisée entre un organe d'une machine et une unité de commande de cette machine, et pour la transcription alpha¬ numérique de l'encodage réalisé constituant repère visible de l 'extérieur d'un boîtier dans lequel ledit circuit est logé, ledit boîtier constituant l'un de deux éléments sépa- râbles au moyen desquels une connexion déconnectable de l 'organe à l'unité de commande est réalisée, l'encodage sus¬ d t consistant à réaliser une connexion de certains d'une pluralité de JΛ conducteurs parallèles à une source de tension. Le circuit Logique susdit comportant des moyens pour lire l 'état de tension de chacun des n conducteurs, pour le comparer avec l 'état instantané de tension d'une autre plu¬ ralité de jπ conducteurs en liaison constante avec ladite unité de commande et pour délivrer un signal d'autorisation d'échange de donnée entre l'organe et l'unité de commande. Selon l'une des caractéristiques principales deTo this end, the invention therefore relates to a device for encoding a logic circuit of decentralized communication between an organ of a machine and a unit for controlling this machine, and for the alpha¬ digital transcription of the encoding carried out constituting a visible marker from the outside of a box in which said circuit is housed, said box constituting one of two elements separable by means which a disconnectable connection from the member to the control unit is made, the sus¬ dt encoding consisting in making a connection of some of a plurality of JΛ conductors parallel to a voltage source. The above logic circuit comprising means for reading the voltage state of each of the n conductors, for comparing it with the instantaneous voltage state of another plu¬ rality of jπ conductors in constant connection with said control unit and for issue a data exchange authorization signal between the member and the control unit. According to one of the main characteristics of
L'invention, il est constitué par un organe se présentant sous la forme d'une feuille mince comportant, d'une part, en regard desdits conducteurs, une pluralité de plages distinc¬ tes les unes des autres chaque plage étant relative à un conducteur et constituant un moyen de liaison ou d'isolation électrique dudit conducteur par rapport à un réseau d'alimen¬ tation, la disposition, les unes par rapport aux autres, des plages conductrices et isolantes déterminant le code désiré, et d'autre part, une ranscription alphanumérique du code susdit portée par une partie de ladite feuille maintenue au voisinage d'une face extérieure visible dudit boîtier.The invention is constituted by a member in the form of a thin sheet comprising, on the one hand, opposite said conductors, a plurality of ranges distinct from each other, each range being relative to a conductor and constituting a means of connecting or electrically isolating said conductor with respect to a power supply network, the arrangement, relative to one another, of conductive and insulating pads determining the desired code, and on the other hand, an alphanumeric transcription of the aforementioned code carried by a part of said sheet held in the vicinity of an external visible face of said casing.
Dans un premier mode de réalisation de l'inven¬ tion, la feui lle est en un matériau isolant, les plages conductrices susdites étant constituées par des découpes, per- forations, embrèvements ou encoches de ladite feuille qui est susceptible d'être insérée de manière amovible sous une pluralité de éléments mobiles constituant les contacts mobiles normalement fermés établissant La liaison électrique entre chacun .desdits conducteurs et le réseau d'alimentation. Une variante de ce premier mode de réalisation réside en ce que La feuille est en matériau isolant, chacune des plages conductrices susdites étant constituée par un dépôt conducteur réalisé sur une surface dudit matériau et constituant liaison électrique entre le conducteur corres- pondant et le réseau d'alimentation.In a first embodiment of the invention, the sheet is made of an insulating material, the aforementioned conductive pads being formed by cuts, perforations, recesses or notches in said sheet which is capable of being inserted from detachably under a plurality of mobile elements constituting the normally closed mobile contacts establishing the electrical connection between each of said conductors and the supply network. A variant of this first embodiment resides in that the sheet is made of insulating material, each of the aforementioned conductive pads consisting of a conductive deposit formed on a surface of said material and constituting an electrical connection between the corresponding conductor and the supply network.
Dans un second mode de réalisation de l'inventio La feui lle est en matériau conducteur, chacune des plages isolantes susdites étant constituée par un dépôt isolant réalisé sur une surface dudit matériau en regard du conduc- teur correspondant, le réseau d'alimentation étant en liaiso électrique avec ledit matériau conducteur.In a second embodiment of the invention, the sheet is made of a conductive material, each of the aforementioned insulating pads being constituted by an insulating deposit produced on a surface of said material facing the corresponding conductor, the supply network being in electric link with said conductive material.
Dans une forme préférée de chacun de ces modes de réalisation, les conducteurs susdits sont constitués pa des pistes portées par au moins une face d'un circuit imprim L 'organe en forme de feui lle étant constitué par une languet te amovible dont une première zone portant lesdites plages est insérée entre ladite face et un organe élastique d'appli cation, au travers d'une paroi du boîtier enfermant Ledit circuit imprimé, et dont une seconde zone portant La trans- cription susdite reste située à l 'extérieur du boîti.er en formant une partie de préhension et de manipulation de lad e languette.In a preferred form of each of these embodiments, the aforesaid conductors consist of tracks carried by at least one face of a printed circuit. The sheet-shaped member being constituted by a removable tongue, a first zone of which carrying said areas is inserted between said face and an elastic application member, through a wall of the housing enclosing said printed circuit, and a second area carrying the above transcription remains located outside the housing. er by forming a gripping and manipulation part of the tongue.
Avantageusement, la seconde zone de la languette est rabattable sur une face du boîtier sensiblement perpen- diculaire à La face du circuit imprimé et constitue en position relative une butée pour l' insertion de ladite Lan¬ guette .Advantageously, the second zone of the tongue is foldable on one face of the housing substantially perpendicular to the face of the printed circuit and constitutes in relative position a stop for the insertion of said lane.
Il existe plusieurs variantes de réalisation de ces languettes selon que celles-ci sont en matériau conduc- teur ou en matériau isolant et dans ce dernier cas, que les plages conductrices sont constituées par un revêtement ou par des impressions.There are several alternative embodiments of these tabs, depending on whether they are made of conductive material or of insulating material and, in the latter case, whether the conductive pads are formed by a coating or by impressions.
Parmi celles-ci on citera, pour une languette en matériau isolant, celle perforée dans laquelle les éléments mobi les sont constitués par des Lames élastiques qui forment les dents d'un peigne relié à une source de tension, paral¬ lèles à ladite face et formant également organe élastique d'application.Among these, mention may be made, for a tongue made of insulating material, of the perforated one in which the movable elements are constituted by elastic blades which form the teeth of a comb connected to a source of tension, parallel to said face and also forming an elastic application member.
On citera également pour la languette isolante selon l ' invention possédant des plages conductrices formées par dépôt, le dispositif dans lequel le réseau d'ali enta- tion comporte un commun d'alimentation porté par ledit circuit i primé, les plages conductrices constituant des liaisons électriques entre ledit commun et chaque conduc- teur correspondant, l 'organe d'application élastique étant un ressort coopérant avec une autre face de la languette.Mention will also be made for the insulating tab according to the invention having conductive areas formed by deposition, the device in which the supply network comprises a supply common carried by said award-winning circuit i, the conductive areas constituting connections electric between said common and each corresponding conductor, the elastic application member being a spring cooperating with another face of the tongue.
Dans une autre forme de chacun de ces modes de réalisation, l 'organe en feui lle mince est constitué par une bande souple disposée de manière permanente dans Ledit boîtier entre un réseau d'alimentation et lesdits conducteur pour assurer Les liaisons électriques correspondant aux codes dési rés, ladite bande comportant une succession de zones identifiées correspondant, pour chacune d'elles, à un code différent, au centre d'une face de languette la trans- cription alphanumérique du repère est réalisée, les plages conductrices ou isolantes susdites étant ménagées sur l'autr face ou le Long d'au moins l 'un de ses bords,par dépôt ou encodiIn another form of each of these embodiments, the thin sheet member is constituted by a flexible strip permanently disposed in said housing between a supply network and said conductors to ensure the electrical connections corresponding to the codes required. res, said strip comprising a succession of identified zones corresponding, for each of them, to a different code, at the center of a tongue face, the alphanumeric transcription of the mark is carried out, the aforementioned conductive or insulating pads being provided on the other side or Along at least one of its edges, by filing or encoding
Dans ce cas, la zone active de ladite bande est voisine d'une fenêtre réalisée dans la paroi du boîtier susdit au travers de laquelle le repère est visible, la bande possédant des moyens pour son entraînement en défi le¬ ment en regard de ladite fenêtre.In this case, the active area of said strip is close to a window made in the wall of the aforementioned case through which the mark is visible, the strip having means for its drive in challenge when facing said window. .
Enfin, le dispositif peut comporter deux bandes parallèles adjacentes par l'un de leur bord, chacune d'elle coopérant avec une fraction des n_ conducteurs et comportant un caractère du repère susdit, la transcription alphanumé¬ rique s'effectuant au moyen de deux caractères.Finally, the device may comprise two adjacent parallel strips by one of their edges, each of them cooperating with a fraction of the n_ conductors and comprising a character of the abovementioned mark, the alphanumeric transcription being effected by means of two characters. .
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 nonlimiting example which will make it possible to identify the advantages thereof. tages and secondary characteristics.

En se reportant tout d'abord aux figures 1 et 2 on voit une lignée collective 1 de circulation des informa- tions codées qui ci rcule le long de la machine ou l'install tion industrielle à partir d'une unité de commande program¬ mable tel qu'un automate non représenté. Le raccordement à cette ligne, de chacun des organes qui sont pilotés par L 'automate est réalisé au moyen de deux éléments séparables dont l 'un est implanté sur la ligne collective 1 susdite et l 'autre raccordé à l'organe, non représenté, au moyen d'un câbl e .Referring first to Figures 1 and 2 we see a collective line 1 of circulation of coded information which flows along the machine or the install industrial tion from a programmable control unit such as a not shown automaton. The connection to this line, of each of the organs which are controlled by the automaton is carried out by means of two separable elements, one of which is installed on the collective line 1 above and the other connected to the organ, not shown, by means of a cable.
Sur la figure 1, le premier élément susdit im¬ planté sur la ligne collective est constitué par un boîtier 3 qui peut comporter des moyens pour dériver ladite ligne collective vers une pluralité d'ensembles de bornes formant plan de pose frontal 4 pour plusieurs éléments, également en forme de boîtiers ou de module 5 raccordés au câble 2. Les moyens contenus dans le boîtier 3 peuvent permettre, si nécessaire, de transformer le protocole de transfert des informations codées, pour que celles-ci soient représentées par l 'ensemble des états de tension de chacun d'une plura¬ lité de conducteurs fixés dans un ordre déterminé. L'en¬ semble des bornes susdit comportera, dans le cas de la figure 1, un sous-ensemble de bornes en nombre égal à la pluralité susdite de conducteurs, qui constitueront les éléments de connexion pour la pluralité de conducteurs corres pondante prévue dans le boîtier ou module 5, dans un circuit de reconnaissance d'adresses. Dans Le module 5, on a représenté schématique- ment ledit circuit de reconnaissance d'adresses constitué par la pluralité 6 de conducteurs susdite, connectables aux bornes correspondantes du boîtier 3, une seconde pluralité 7 de conducteurs coopérant avec un dispositif d'encodage 8 et un circuit électronique comparateur 9 qui délivre en sortie à un circuit d'adaptation 10, un ordre de lecture ou d'écriture qui permet le transfert d'une donnée le long de la Ligne 1 en direction de L'organe, ou en direction de L 'automate programmable selon que le module 5, de "sortie" ou "d'entrée", est relatif à un organe récepteur ou un organe émetteur d'information.In FIG. 1, the aforementioned first element im¬ planted on the collective line is constituted by a box 3 which may include means for diverting said collective line towards a plurality of sets of terminals forming a frontal laying plane 4 for several elements, also in the form of boxes or of module 5 connected to the cable 2. The means contained in the box 3 can make it possible, if necessary, to transform the protocol for transferring the coded information, so that it is represented by all of the states of voltage of each of a plurality of conductors fixed in a determined order. The above-mentioned set of terminals will comprise, in the case of FIG. 1, a subset of terminals equal in number to the above-mentioned plurality of conductors, which will constitute the connection elements for the corresponding plurality of conductors provided in the box or module 5, in an address recognition circuit. In Module 5, there is shown schematically said address recognition circuit constituted by the plurality 6 of the above conductors, connectable to the corresponding terminals of the housing 3, a second plurality 7 of conductors cooperating with an encoding device 8 and an electronic comparator circuit 9 which delivers, at the output to an adaptation circuit 10, a read or write order which allows the transfer of data along Line 1 in the direction of the organ, or in the direction of The programmable automaton depending on whether module 5, "output" or "input", relates to a receiving member or a member sender of information.
Dans le schéma de la figure 2, qui illustre une autre possibi lité de raccordement d'un organe à une Ligne de circulation des informations 1, le boîtier 13 comprend, outre les moyens électroniques d'interface et de dérivation de l ' information codée, un circuit de reconnais¬ sance d'adresses comportant comme dans ce cas précédent, deux pluralités 16 et 17 de conducteurs, dont l'une coopère avec un dispositif d'encodage 18, aboutissant à un circuit comparateur électronique 19 qui délivre en sortie, en cas d'identité d'adresses entre celle des conducteurs 16 et celle des conducteurs 17, un ordre d'échange de signal entre l'organe et l 'automate. Comme dans le cas précédent, le boît 13 comporte une surface de connexion 14 pour une pluralité de modules ou boîtiers 15, cette surface présentant un nombre de bornes de connexion, pour chaque module, beaucoup plus réduit que dans le cas précédent. On aura prévu, de manière avantageuse que le boîtier 13 présente une surface frontale 20 sur laquelle apparaît, en regard de chaque module 15, le repère du dispositif d'encodage 18 afin d'éta¬ blir une correspondance visuelle simple entre le dispositif 18 et le module 15. On notera que cette correspondance est, dans le cas de la figure 1, automatique puisque le dispositi de repérage-encodage 8 est porté directement par le module 5 Dans la pratique, la réalisation du câblage au moyen des boîtiers de raccordement décrits ci-dessus consiste à mettre en place les boîtiers tels que 3 et 13 le Long de la ligne 1 qui offrent ainsi en attente une pluralit de zones de connexion, toutes identiques, pour des modules tels que 5 et 15. Lesdits modules, préalablement reliés à chaque organe par le câble 2, sont ensuite enfichés sur le.s boîtiers de connexion 3 ou 13 et dans le même temps, la Liaison ainsi réalisée est encodée pour permettre l 'échange sélectif d'informations entre l'unité de commande progra - able et chaque module. L'opération d'encodage consiste, au moyen d'un dispositif approprié qui sera décrit par la suite à connecter la pluralité des conducteurs 7 ou 17, à une source de tension dans un arrangement déterminé qui corres¬ pond à l 'adresse par laquelle, dans le programme de l'unité programmable. L'organe a été nommé. Pour l 'opérateur chargé du câblage, l'encodage consiste à afficher sur le module 5 ou sur La partie de boîtier 13 en regard du module 15, au moyen du dispositif d'encodage, un repère (6A) correspondant au repère affecté préalablement à l 'organe et ce, dès la conception de la machine. Le dispositif d'encodage effectue lui-même la traduction de ce repère en un code exploitable par l'unité de commande. On voit que par un tel dispositif, le réalisateur de la machine et, par la suite, l'uti lisa¬ teur assurant l'exploitation de sa machine, ayant donc besoi de la régler, de l'entretenir ou voulant la modifier, n'ont pas à se soucier d'établir une liaison entre un organe et des bornes prédéterminées qui, dans le programme de l'auto¬ mate de commande, sont affectées à l'organe, mais n'ont qu'à rappeler sur l'un des boîtiers de raccordement le repère de l 'organe, au moyen d'un dispositif dont quelques exemples de réalisation sont décrits en regard des figures suivantes .In the diagram of FIG. 2, which illustrates another possibility of connecting an organ to a line for circulating information 1, the box 13 comprises, in addition to the electronic means for interfacing and deriving the coded information, an address recognition circuit comprising, as in this previous case, two pluralities 16 and 17 of conductors, one of which cooperates with an encoding device 18, leading to an electronic comparator circuit 19 which delivers as an output, case of identity of addresses between that of the conductors 16 and that of the conductors 17, a signal exchange order between the member and the automaton. As in the previous case, the box 13 has a connection surface 14 for a plurality of modules or boxes 15, this surface having a number of connection terminals, for each module, much smaller than in the previous case. Advantageously, provision will have been made for the housing 13 to have a front surface 20 on which appears, opposite each module 15, the mark of the encoding device 18 in order to establish a simple visual correspondence between the device 18 and the module 15. It will be noted that this correspondence is, in the case of FIG. 1, automatic since the locating-encoding device 8 is carried directly by the module 5 In practice, carrying out the wiring by means of the connection boxes described above consists in setting up the boxes such as 3 and 13 along the line 1 which thus offer on standby a plurality of connection zones, all identical, for modules such as 5 and 15. Said modules, previously connected to each member by the cable 2, are then plugged into the connection boxes 3 or 13 and at the same time, the link thus produced is encoded to allow selective exchange of information. ns between the programmable control unit and each module. The encoding operation consists, at means of a suitable device which will be described later on to connect the plurality of conductors 7 or 17 to a voltage source in a determined arrangement which corresponds to the address by which, in the program of the programmable unit . The body has been appointed. For the operator responsible for wiring, encoding consists in displaying on the module 5 or on the housing part 13 opposite the module 15, by means of the encoding device, a mark (6A) corresponding to the mark previously assigned to the organ and this, from the conception of the machine. The encoding device itself translates this reference into a code that can be used by the control unit. We see that by such a device, the maker of the machine and, thereafter, the user ensuring the operation of his machine, therefore needing to adjust it, maintain it or want to modify it, n 'do not have to worry about establishing a link between an organ and predetermined terminals which, in the program of the automatic control unit, are assigned to the organ, but need only recall on the one of the connection boxes the reference of the member, by means of a device of which some embodiments are described with reference to the following figures.
C'est ainsi que, sur la figure 3 on retrouve un module 5 ou boîtier 13 qui comporte, sous la forme d'un ci rcuit imprimé 21 la pluralité de conducteurs 7, 17 susdite. conducteur 22, du circuit imprimé forme une liaison élec¬ trique ou commun de tension entre une source non représent et une pièce 24 formant pont au-dessus des conducteurs 7,17, et possédant des lames flexibles 25, tournées en direction de l 'extrémité du circuit imprimé 21 proche de la paroi frontale 26 du module 5 ou boîtier 13 et normalement en contact, pour chacune d'elle, avec l'un des conducteurs de la pluralité susdite. La paroi frontale 26 possède,quant à elle, une fente 27.d ' introduction d'une languette 28, alignée avec la surface du circuit imprimé 21 portant les conducteurs 7, 17 et prolongée à L'intérieur du boîtier par des moyens de guidage non représentés. La Languette 28 peut ainsi être glissée entre les conducteurs 7, 17 et Les pattes 25 et surélever celles-ci ou une partie de celles-ci selon La découpe de son bord Logé à L' ntérieur du boîtier ou module. La figure 3A montre une languette 28. Cette languette est réalisée en matériau isolant et possède, sur son bord 28a, des encoches 29 dont le nombre et l'espacement déterminent Lesquels, parmi les conducteurs 7, 17, seront connectés à La source de tension par La pièce 24 en forme de peigne. Les dents 30 restantes de la languette constituant moyen d'interruption du contact entre le conducteur et la lame flexible 25, en étant glissée entre eux. IL en résulte donc un état de tension de la pluralité des conducteurs 7, 17 qui constitue Le code placé en consigne dans le circuit de reconnaissance d'adresses.Thus, in Figure 3 there is a module 5 or housing 13 which comprises, in the form of a printed printed circuit 21 the plurality of conductors 7, 17 above. conductor 22 of the printed circuit forms an electrical or common voltage connection between a source not shown and a part 24 forming a bridge above the conductors 7, 17, and having flexible blades 25, turned in the direction of the end of the printed circuit 21 close to the front wall 26 of the module 5 or box 13 and normally in contact, for each of them, with one of the conductors of the above-mentioned plurality. The front wall 26 has, for its part, a slot 27. Introduction of a tongue 28, aligned with the surface of the printed circuit 21 carrying the conductors 7, 17 and extended inside the housing by means of guidance, not shown. The tab 28 can thus be slid between the conductors 7, 17 and the tabs 25 and raise them or a part thereof according to the cut of its edge housed inside the housing or module. FIG. 3A shows a tongue 28. This tongue is made of insulating material and has, on its edge 28a, notches 29 whose number and spacing determine which of the conductors 7, 17 will be connected to the voltage source by Piece 24 in the shape of a comb. The remaining teeth 30 of the tongue constituting means for interrupting contact between the conductor and the flexible blade 25, by being slid between them. IL therefore results in a voltage state of the plurality of conductors 7, 17 which constitutes the code placed as a setpoint in the address recognition circuit.
En prenant L'exemple de La figure 3A, on supposera que La pluralité 7, 17 comporte huit conducteurs côte à côte. Le bord 28a de la Languette est divisé, comme Le montre Le dessin, en huit zones identiques. Les zones, examinées de bas en haut sur La figure, un, deux, quatre, six et sept sont encochées, et Les zones trois, cinq et huit constituent les dents 30 susdites. Cette languette, glissée sous Les Lames élastiques 25 confère un code, lu de bas en haut et expr mé en binaire 11010110 au circuit de reconnaissance d'adresse, 0 et 1 correspondant respec¬ tivement à un état de chacun des conducteurs (au nombre de huit également) de La pluralité 7, 17 susdite. La lan¬ guette 28 possède une partie 28b qui porte la transcπ'p- tion alphanumérique du code réalisé, c'est-à-dire dans le cas présent, 214 en écriture décimale ou D 6 en écri¬ ture hexadécimale. Cette partie 28b qui, dans la figure 3A est dans Le même plan que le reste de la languette, peut être repliée à 90° Le long d'une Ligne de pliure 31 afin de s'étendre, lorsqu'elle coopère avec Le boîtier 13 ou Le module 5, sur La face frontale 26 de ce dernier et cons¬ tituer une butée à l'introduction de la languette dans la fente 27.Taking the example of Figure 3A, it will be assumed that the plurality 7, 17 has eight conductors side by side. The edge 28a of the tongue is divided, as shown in the drawing, into eight identical zones. The areas, examined from bottom to top in the figure, one, two, four, six and seven are notched, and The areas three, five and eight constitute the above teeth. This tab, slid under The elastic blades 25 confers a code, read from bottom to top and expressed in binary 11010110 to the address recognition circuit, 0 and 1 corresponding respectively to a state of each of the conductors (the number of also eight) of The plurality 7, 17 above. The lan¬ watches 28 has a part 28b which carries the transcπ alphanumeric tion of p- realized code, that is to say, in this case, 214 in decimal notation or D 6 écri¬ hexadecimal ture. This part 28b which, in FIG. 3A is in the same plane as the rest of the tongue, can be folded at 90 ° along a fold line 31 so as to extend, when it cooperates with the housing 13 where the module 5, on the front face 26 of the latter and constituting a stop for the introduction of the tongue into the slot 27.
Sur la figure 4 et la figure 4A on a représent une variante de réalisation de la figure 3 dans laquelle la languette est en deux parties 40 et 41, chacune de ces parties coopérant avec la moitié des lames élastiques 25 de la pièce 24 en forme de peigne. Dans cette forme de réalisa¬ tion, les deux languettes 40, 41 possèdent des extensions 40]3, 41b_ repliables, portant pour chacune d'elles, une partie de la transcription alphanumérique du code conféré par les encoches susdites. Cette disposition s'applique tout particulièrement à une transcription du code dans un système alphanumérique hexadécimal, chacune des 16 combinaisons d'encoches de chaque languette étant représentée par un chiffre ou une lettre.In Figure 4 and Figure 4A there is shown an alternative embodiment of Figure 3 in which the tongue is in two parts 40 and 41, each of these parts cooperating with half of the elastic blades 25 of the part 24 in the form of comb. In this embodiment, the two tongues 40, 41 have foldable extensions 40] 3, 41b_, carrying for each of them, part of the alphanumeric transcription of the code given by the aforesaid notches. This provision particularly applies to a transcription of the code in a hexadecimal alphanumeric system, each of the 16 combinations of notches of each tab being represented by a number or a letter.
La figure 5 montre par schéma qu'un encodage- repérage, réalisé au moyen de deux languettes séparées 42, 43, peut être appliqué dans le cas où la pluralité de conducteurs est portée, soit par deux circuits imprimés non représentés, soit par les deux faces parallèles 44, 45 d'un circuit imprimé double face. On voit que dans cette appli¬ cation, les parties rabattables 40b 41b_ des languettes sont placées dans l'alignement l'une de l'autre pour former un panneau unique d'affichage dudit repère.FIG. 5 shows by diagram that an encoding-marking, carried out by means of two separate tabs 42, 43, can be applied in the case where the plurality of conductors is carried, either by two printed circuits not shown, or by both parallel faces 44, 45 of a double-sided printed circuit. We see that in this appli¬ cation, the foldable parts 40b 41b_ of the tongues are placed in alignment with one another to form a single display panel of said reference.
On peut imaginer, sans sortir du cadre de l'invention, que la pluralité de conducteur soit répartie sur plusieurs surfaces parallèles de circuits imprimés, chacune d'elle comportant un peigne tel que celui 46 de la figure 5 et que le code soit réalisé avec autant de lan¬ guettes qu'i l y a de surfaces, les parties rabattables d'af¬ fichage du repère étant en position finale toutes alignées et formant une transcription du code à plusieurs caractères au moyen de laquelle on peut rendre intelligible non seule- ment le repère de l'organe, mais également son identification abrégée (soit par sa nature, soit par sa fonction).One can imagine, without departing from the scope of the invention, that the plurality of conductors is distributed over several parallel surfaces of printed circuits, each of them comprising a comb such as that 46 of FIG. 5 and that the code is produced with as many screens as there are surfaces, the foldable parts of display of the marker being in the final position all aligned and forming a transcription of the code with several characters by means of which one can make intelligible not only the organ landmark, but also its identification abbreviated (either by its nature or by its function).
La figure 9 illustre une telle disposition dans laquelle chaque languette élémentaire 50 possède une partie d'encodage 50a_ pourvue non plus d'encoches, mais d'orifices 51 au travers desquels les contacts seront main¬ tenus fermés et une partie de repérage 50b_ portant une lettre ou un chiffre qui, associé aux autres lettres ou chiffres des languettes élémentaires adjacentes formera un mot porteur d'un message plus élaboré (AVB6) . On notera à cet égard que la disposition de la figure 9 pourra s'appli¬ quer dans le cas où, par exemple, la pluralité de conduc¬ teurs s'étendrait par nappes perpendiculaires au plan de figure, chaque conducteur étant terminé par un élément mobile en continuité électrique avec lui, normalement en contact avec une plaque de potentiel parallèle au plan de figure, et pouvant être écarté de cette plaque par les parties non ajourées des languettes glissées entre eux et la plaque.FIG. 9 illustrates such an arrangement in which each elementary tongue 50 has an encoding part 50a_ no longer provided with notches, but with orifices 51 through which the contacts will be kept closed and a locating part 50b_ carrying a letter or a number which, associated with the other letters or numbers of the adjacent elementary tongues will form a word carrying a more elaborate message (AVB6). It will be noted in this respect that the arrangement of FIG. 9 could apply in the case where, for example, the plurality of conductors would extend in sheets perpendicular to the plane of the figure, each conductor being terminated by an element mobile in electrical continuity with it, normally in contact with a potential plate parallel to the plane of the figure, and being able to be moved away from this plate by the non-perforated parts of the tongues slid between them and the plate.
Les figures 6, 7 et 8 montrent diverses varian¬ tes de réalisation des languettes. Sur la figure 6, la lan- guette 60 représentée est semblable à celle de la figureFigures 6, 7 and 8 show various varian¬ your embodiment of the tongues. In FIG. 6, the tongue 60 shown is similar to that of FIG.
3A, la ligne de pliage de la partie 60b^ étant perpendiculaire au bord encoche au lieu d'y être parallèle comme dans la figure susdi te .3A, the fold line of the part 60b ^ being perpendicular to the notched edge instead of being parallel to it as in the above figure.
La figure 7 montre une languette 70 semblable à celle de la figure 6 dans laquelle la partie d'encodage, possède des ouvertures 70a_ répondant aux mêmes critères de disposition géométriques que les encoches ci-dessus décritFIG. 7 shows a tongue 70 similar to that of FIG. 6 in which the encoding part has openings 70a_ meeting the same criteria of geometric arrangement as the notches described above
Sur la figure 8, enfin, on a représenté une variante de réalisation de la figure 4A dans laquelle les deux languettes 80, 81 présentent des ouvertures 8θ , 81a_ au lieu d'encoches et peuvent être utilisés dans une appli¬ cation semblable à celle illustrée schémat i quement en figure 5.In FIG. 8, finally, an alternative embodiment of FIG. 4A has been shown in which the two tongues 80, 81 have openings 8θ, 81a_ instead of notches and can be used in an application similar to that illustrated. schematically in Figure 5.
La figure 10 montre par une vue en coupe, une variante de réalisation du dispositif selon l'invention, dans laquelle les conducteurs 100 sont portés par une face 101 d'un circuit imprimé 101 qui porte également un commun d'alimentation 102 au potentiel duquel certains des conduc¬ teurs 100 doivent être portés pour constituer le code. La connexion sélective de ces conducteurs au commun est assurée par une languette 103 en matériau isolant dont une face 103a_ est pourvue de plages conductrices 104 susceptibles d'être placées en chevauchement entre le commun 102 et les conducteurs 100 concernés. La partie 103b_ de la languette 103 porte la transcription 105 du code réalisé et constitue le repère visible à l'extérieur du boîtier 106. Une pièce é'iastique 107 constitue organe d'application de la face 103a_ de la Languette contre la face 101a_ du circuit imprimé pour garantir une bonne qualité des contacts réalisés. Sur la figure 11, la languette 113 est en un matériau conducteur. Elle comporte, sur sa face 113a_ des plages isolantes 114. Ainsi les conducteurs 110 du circuit imprimé 111, situés en regard de ces plages, sont isolés de la Languette 113. Une pièce conductrice 117 en forme de Lame élastique (simple ou multiple) a pour effet d'appliquer la face 113a_ de la Languette 113 contre la face 111a_ du circuit imprimé. Etant en outre reliée électriquement à un commun d'alimentation 112, elle porte la Languette 103 au potentiel auquel les conducteurs, non isolés de la languette, doivent être portés. La partie coudée 113b_ de la languette porte également le repère 115 visible de l'extérieur du boîtier 116FIG. 10 shows, in a sectional view, an alternative embodiment of the device according to the invention, in which the conductors 100 are carried by one face 101 of a printed circuit 101 which also carries a supply common 102 at the potential of which some of the conductors 100 must be carried to constitute the code. The selective connection of these conductors to the common is provided by a tongue 103 of insulating material, one face 103a_ is provided with conductive pads 104 capable of being placed in overlap between the common 102 and the conductors 100 concerned. The part 103b_ of the tongue 103 carries the transcription 105 of the code produced and constitutes the visible mark on the outside of the housing 106. An elastic piece 107 constitutes a member for applying the face 103a_ of the Tongue against the face 101a_ of the printed circuit to guarantee good quality of the contacts made. In Figure 11, the tongue 113 is made of a conductive material. It has, on its face 113a_ insulating pads 114. Thus the conductors 110 of the printed circuit 111, located opposite these pads, are isolated from the tongue 113. A conductive part 117 in the form of elastic blade (single or multiple) has the effect of applying the face 113a_ of the tab 113 against the face 111a_ of the printed circuit. Being also electrically connected to a power supply common 112, it carries the Tab 103 to the potential to which the conductors, not isolated from the tab, must be brought. The angled portion 113b_ of the tongue also carries the mark 115 visible from the outside of the housing 116
Les plages conductrices sur languette isolante ou isolantes sur Languette conductri ce, peuvent être rappor¬ tées par impression en même temps que L 'impression du repère correspondant. L'avantage des variantes, selon les figures 10 et 11 par rapport aux figures précédentes, réside dans La plus grande simp L i c i té des formes de languette, et donc dans un outillage et un processus de fabrication moins onéreux . Ces modes de réalisation du dispositif d'enco- dage repérage selon l'invention par Languettes, présentent un avantage important dans Le fait qu'ils peuvent être fabriqués en série de manière séparée du reste du dispositif de raccor¬ dement avec des moyens permettant d'associer de manière auto- matique et permanente, les encochages, perforations ou im¬ pressions avec le repère ou le caractère alphanumérique cor¬ respondant. Cette fabrication peut être réalisée sur le lieu même du montage et de l'exploitation de l'installation au moyen d'un outillage de développement dans lequel on introdui des ébauches de languettes. L'installateur disposant de cet outillage peut fabriquer à la demande Les languettes dont il a besoin. L'outillage possède à cet effet des moyens pour réaliser la présélection d'un repère quelconque, parmi Les repères possibles et pour réaliser l'encochage ou l'impressio de la languette correspondant au repère select i onné, en même temps que l'impression ou le marquage du repère sur La Lan¬ guette et ce, de manière automatique. La concordance entre l'encochage et la mention du repère est réalisée par des moyen mécan ques ou électroniques internes à l'outil afin d'éviter toute erreur sur une même languette. Cet outillage de dévelop pement peut également comporter un dispositif de vérification de la concordance du code et du repère de chaque languette.The conductive pads on the insulating tab or the insulating tabs on the conductive tab can be brought in by printing at the same time as the printing of the corresponding mark. The advantage of the variants, according to FIGS. 10 and 11 compared to the preceding figures, resides in the larger simp L here tee of the tongue forms, and therefore in a less expensive tooling and manufacturing process. These embodiments of the device for dage location according to the invention by Tabs, have an important advantage in The fact that they can be manufactured in series separately from the rest of the connection device with means for associating automatically and permanently, notches, perforations or prints with the corresponding mark or alphanumeric character. This manufacture can be carried out on the very place of assembly and operation of the installation by means of a development tool in which blanks of tongues are introduced. The installer with this tool can make the tabs he needs on demand. The tooling has for this purpose means for preselecting any mark, among the possible marks and for making the notching or printing of the tab corresponding to the mark select i onné, at the same time as printing or marking the mark on La Lan¬ guette and this, automatically. The concordance between the notching and the reference to the reference is made by mechanical or electronic means internal to the tool in order to avoid any error on the same tab. This development tool can also include a device for verifying the agreement of the code and the mark of each tab.
On préférera cependant un autre mode de fabrica¬ t on des languettes, beaucoup plus industriel, consistant en l'édition de planches portant ces languettes prêtes à l'emplo qu'il suffit de détacher manuellement, une à une, au fur et à mesure des besoins.We will however prefer another way of manufacturing tabs, much more industrial, consisting of the edition of boards carrying these ready-to-use tongues which it suffices to detach manually, one by one, as and when needs.
Chacune de ces planches sera constituée par le matériau en feuille (isolant ou conducteur) constitutif de chaque languette associé, de manière adhésive par exemple, à un support. Une installation d'impression et de prédécoupag permettra d'apposer par impression sur le matériau en feuille la pluralité des repères offerts puis de prédécouper, autour d chaque repère, une languette comportant le nombre et la dis- position des encoches constituant le code correspondant au repère i primé.Each of these boards will consist of the sheet material (insulator or conductor) constituting each tab associated, in an adhesive manner for example, with a support. A printing and precut installation will make it possible to affix by printing on the sheet material the plurality of marks offered and then to precut, around each mark, a tab comprising the number and the arrangement of the notches constituting the code corresponding to the landmark i awarded.
Ce mode de fabrication est encore plus avantageu dans le cas où le code est constitué par dépôt de matière isolante ou conductrice sur des plages déterminées du matéria en feuille. En effet ce dépôt peut également être réalisé par l'impression, le prédécoupage étant alors simplifié et iden¬ tique pour toutes les languettes. Ce prédécoupage n'atteint pas le support du matériau qui constitue l'élément de liaison des languettes sur la planche. On peut également réaliser sur la planche des impressions secondaires du seul repère, dans Les zones intercalaires entre les languettes, qui égale¬ ment prédécoupées, peuvent constituer des étiquettes à im¬ planter, par exemple aux extrémités du câble de liaison entre L'organe et son boîtier de raccordement. On a constaté que 256 repères différents par type d'organes, récepteur ou émetteur , était un nombre pouvant convenir pour La réalisation de La plupart des ins¬ tallations. Une fabrication standard consiste donc à éditer des lots de planches de 256 languettes, une languette déter- minée n'étant présente qu'une fois dans chaque lot. L'instal¬ lateur câbleur aura à sa disposition un seul lot de planches par type d'organes ,ce qui permettra d'éviter La double uti¬ lisation d'un même repère.This manufacturing method is even more advantageous in the case where the code is formed by depositing insulating or conductive material on specific areas of the sheet material. In fact, this deposit can also be made by printing, the precut being then simplified and identical for all the tongues. This precut does not reach the support of the material which constitutes the connecting element of the tongues on the board. It is also possible to make secondary prints on the board of the single marker, in the intermediate zones between the tongues, which also pre-cut, can constitute labels to be planted, for example at the ends of the connecting cable between the member and its connection box. It has been found that 256 different references by type of member, receiver or transmitter, was a number which may be suitable for the realization of most installations. Standard production therefore consists of editing batches of boards with 256 tabs, a specific tab being present only once in each batch. The cable installer will have at his disposal a single batch of boards per type of member, which will avoid double use of the same marker.
La figure 12 illustre un second mode de réalisa- tion de L'invention par un schéma montrant dans un boîtier ou un module 120, un dispositif d'encodage constitué par deux bandes 121 et 122 en matériau isolant et souple montées à coulissement sur une pièce de guidage 123 disposée en regard d'une fenêtre 120a du boîtier 120. La surface 123a de la pièce 1 3 est conductrice et reliée à une source de poten¬ tiel non représentée. Des griffes latérales conductrices 125a, 125b, portées par la pièce 123, sont électriquement isolées l'une de l'autre et de la surface 123a à L'exception de leur extrémité libre en surplomb de la surface 123a et qui repose élastiquement sur cette surface. Les conducteurs 125a_, 125J3 sont, par ailleurs, reliés à chacun des conduc¬ teurs de la pluralité de conducteurs telle que celle 7,17 décrite en regard des figures 1 et 2, qui peuvent être portés par un support de circuit imprimé 126. Chaque bande 121, 122 est divisée en zones égales et successives 121a_, 122a_ portant sur leur bord non adjacent à l 'autre bande des encoches 127, ménagées en fonc¬ tion du pas d'implantation des griffes 125a_, 125b_, selon les mêmes critères que les encoches des Languettes décrites en regard des figures précédentes. Des orifices 128 dans chaque bande permettent, au moyen d'un objet pointu, d'amener L'une des zones 121a_, 122a_ en regard de la fenêtre 1 θ . Le centra¬ ge de cette mise en place peut être assuré par un moyen d ' enc l i quetage (un bossage de la surface 123a_) coopérant avec les orifices 128. Enfin, la surface centrale de chaque zone 121a_, 122a_ porte une transcription alphanumérique 129 du code réalisé par les encoches 127. On voit ainsi que pour chaque zone 121a_, 122a_ placée sur la surface 123a_, entre celle-ci et les griffes 125a, 125b_, on dete.rn.ine une connec- tion particulière des conducteurs du circuit électronique de reconnaissance d'adresses avec une source de potentiel, certaines de ces griffes étant isolées de la surface 123a_ par le bord de bande non encoche, d'autres restant au contact de cette surface au travers des encoches. Avec deux bandes côte à côte, comportant chacun seize zones successives coopérant avec deux groupes de quatre griffes chacun, on peut réaliser 256 combinaisons différen¬ tes de connexion à une source de potentiel d'une pluralité de huit conducteurs. Si l'on désire un nombre moins impor- tant de combinaisons possibles, on peut réduire le nombre de griffes et on n'utilise qu'une seule bande encochée.FIG. 12 illustrates a second embodiment of the invention by a diagram showing in a housing or a module 120, an encoding device constituted by two strips 121 and 122 of insulating and flexible material mounted to slide on a part. guide 123 disposed opposite a window 120a of the housing 120. The surface 123a of the part 1 3 is conductive and connected to a source of potential not shown. Conductive lateral claws 125a, 125b, carried by the piece 123, are electrically insulated from each other and from the surface 123a with the exception of their free end overhanging the surface 123a and which rests elastically on this surface . The drivers 125a_, 125J3 are, moreover, connected to each of the conductors of the plurality of conductors such as that 7.17 described with reference to Figures 1 and 2, which can be carried by a printed circuit support 126. Each strip 121 , 122 is divided into equal and successive zones 121a_, 122a_ bearing on their edge not adjacent to the other strip of notches 127, formed as a function of the pitch of implantation of the claws 125a_, 125b_, according to the same criteria as the notches Tabs described with reference to the previous figures. Holes 128 in each strip make it possible, by means of a pointed object, to bring one of the zones 121a_, 122a_ opposite the window 1 θ. The centra¬ ge of this implementation can be ensured by means of enc liketing (a boss of the surface 123a_) cooperating with the orifices 128. Finally, the central surface of each zone 121a_, 122a_ carries an alphanumeric transcription 129 of the code produced by the notches 127. It can thus be seen that for each zone 121a_, 122a_ placed on the surface 123a_, between the latter and the claws 125a, 125b_, we dete.rn.ine a particular connection of the conductors of the circuit address recognition electronics with a potential source, some of these claws being isolated from the surface 123a_ by the edge of the strip not notched, others remaining in contact with this surface through the notches. With two bands side by side, each comprising sixteen successive zones cooperating with two groups of four claws each, it is possible to produce 256 different combinations of connection to a potential source of a plurality of eight conductors. If you want a lower number of possible combinations, you can reduce the number of claws and use only one notched strip.
Sur la figure 13 enfin, on a représenté schéma- tiquement par une vue partielle une variante de réalisation de La figure 12 dans Laquelle les deux bandes 131, 132 sont en matériau isolant, divisées en zones successives, chacune des zones présentant un arrangement de plages conductrices 137 qui peuvent établir une continuité électrique entre des conducteurs 135a_, 135JD et un commun d'alimentation 136 portés par une pièce de guidage 133, lorsque ces zones sont placées au droit de la face frontale de cette pièce. Cette variante de réalisation est la transposition de la variante de réalisation selon la figure 10, pour ce qui concerne les languettes. On peut prévoir, sans sortir du cadre de l'inven¬ tion, des bandes conductrices comportant des plages isolantes Alors que dans le cas des languettes celles-ci sont à rapporter sur le boîtier de raccordement pour réaliser l'encodage repérage, dans le cas des bandes, le boîtier est livré avec son dispositif d'encodage repérage incorporé, le choix du code s'effectuant par la sélection de la zone de chaque bande à placer en regard des conducteurs du circuit électronique de reconnaissance d'adresses. Pour éviter aux bandes d'être mises hors service, on aura prévu des bourre¬ lets 130 (figure 12) à chacune de Leurs extrémités faisant office de butée contre des éléments fixes solidaires du boîtier 120 ou du support 126 de circuit imprimé.Finally, in FIG. 13 is shown diagrammatically by a partial view an alternative embodiment of FIG. 12 in which the two strips 131, 132 are made of insulating material, divided into successive zones, each zones having an arrangement of conductive pads 137 which can establish electrical continuity between conductors 135a_, 135JD and a supply common 136 carried by a guide piece 133, when these areas are placed in line with the front face of this piece . This variant embodiment is the transposition of the variant embodiment according to FIG. 10, as far as the tongues are concerned. It is possible to provide, without departing from the scope of the invention, conductive strips comprising insulating pads Whereas, in the case of the tabs, these are to be attached to the connection box in order to carry out the coding, in the case of strips, the box is delivered with its incorporated coding and marking device, the choice of code being made by selecting the zone of each strip to be placed opposite the conductors of the electronic address recognition circuit. To prevent the strips from being put out of service, provision will be made for bourre¬ lets 130 (FIG. 12) at each of their ends acting as a stop against fixed elements integral with the housing 120 or the support 126 of the printed circuit.
L'invention trouve une application dans le domaine des automatismes. The invention finds an application in the field of automation.
