Description

La présente invention concerne un appareil électrique du type disjoncteur, bloc ou interrupteur différentiel, comportant un boítier isolant prévu pour être monté sur un rail support accolé à des boítiers d'appareils électriques du même type pour constituer un circuit de distribution électrique, par exemple disposé dans un tableau de distribution.The present invention relates to an electrical device of the circuit breaker, block type. or differential switch, comprising an insulating housing designed to be mounted on a support rail attached to housings of electrical devices of the same type for constitute an electrical distribution circuit, for example arranged in a switchboard of distribution.

Ces appareils étant montés sur lesdits rails en rangées successives, leur connexion au circuit, au moyen de conducteurs externes, se fait dans des faces perpendiculaires d'une part à leur plan d'accolement, et d'autre part aux rails de montage. Des orifices menant aux dits moyens de connexion sont pratiqués dans ces faces, qui sont par conséquent accessibles pour un utilisateur selon une direction d'action verticale, et dans un volume réduit séparant les faces de raccordement de deux rangées adjacentes.These devices being mounted on said rails in successive rows, their connection to the circuit, by means of external conductors, is made in faces perpendicular on the one hand to their abutment plane, and on the other hand to the rails of mounting. Holes leading to said connection means are made in these faces, which are therefore accessible to a user according to a vertical direction of action, and in a reduced volume separating the faces of connection of two adjacent rows.

Lorsque les moyens de connexion sont réalisés par un dispositif à cage et vis, les têtes de vis sont accessibles depuis la façade du produit, située directement en face de l'utilisateur de sorte que le serrage/déserrage puisse être effectué avec une bonne visibilité. L'insertion des câbles, barres de pontage, etc. dans les cages est en revanche plus malaisée, notamment si le tableau de distribution est bien rempli, et que les câbles/barres de distribution sont nombreux. Le fait que les orifices d'insertions ne soient pas ou peu visibles, l'exiguïté du volume d'accès à ces orifices, ainsi que des conditions d'éclairage dans le tableau de distribution qui ne sont pas toujours optimales, rendent parfois la tâche du monteur compliquée. When the connection means are produced by a cage and screw device, the screw heads are accessible from the front of the product, located directly in face of the user so that tightening / loosening can be done with a good visibility. Insertion of cables, bridging bars, etc. in the east cages however more difficult, especially if the distribution board is full, and that there are many cables / distribution bars. The fact that the holes of insertions are not or hardly visible, the smallness of the volume of access to these orifices, as well as lighting conditions in the distribution panel which do not are not always optimal, sometimes make the fitter's task complicated.

Pour faciliter les opérations de connexion, les moyens classiques à cage et vis sont de plus en plus souvent remplacés par des dispositifs de raccordement rapide, basés sur une lame ressort précontrainte en appui sur la borne électrique d'entrée ou de sortie de l'appareil, et qui permet l'introduction par enfichage d'un conducteur. L'opération de raccordement est quasi immédiate, par comparaison avec la connexion dans une cage traditionnelle, pour laquelle il faut maintenir le conducteur au moins pendant une partie du vissage de la vis de serrage. Toutefois, l'orifice menant aux moyens de raccordement rapide est en général de taille inférieure à celui sur lequel débouchent les cages, et l'introduction de l'extrémité d'un conducteur peut par conséquent parfois s'avérer malaisée.To facilitate connection operations, conventional cage and screw means are more and more often replaced by connecting devices fast, based on a pre-stressed spring leaf resting on the electrical terminal input or output of the device, and which allows the insertion by insertion of a driver. The connection operation is almost immediate, by comparison with the connection in a traditional cage, for which the conductor at least during part of the tightening screw tightening. However, the opening leading to the quick connection means is generally large lower than that on which the cages lead, and the introduction of the end of a driver can therefore sometimes be difficult.

L'existence de plusieurs niveaux de pontage, sur une même face, permettant la connexion simultanée d'une barre de pontage et d'un conducteur individuel n'arrange à cet égard pas les choses. La ou les barres de pontage sont en effet souvent situées plus proches de la façade que l'ouverture d'introduction du conducteur individuel, et elle(s) masque(nt) parfois l'orifice de raccordement dudit conducteur individuel.The existence of several bridging levels, on the same face, allowing the simultaneous connection of a bridging bar and an individual conductor does not help matters in this regard. The bridging bar (s) are indeed often located closer to the facade than the opening for introducing the individual conductor, and it (s) sometimes mask (s) the connection orifice of said individual driver.

Pour faciliter la connexion, et notamment s'affranchir des problèmes liés à l'exiguïté et au manque de visibilité, il a été proposé que les moyens de connexion soient amovibles, c'est-à-dire détachables du boítier, de telle sorte que la connexion puisse être faite indépendamment de la localisation dudit boítier. C'est notamment l'objet du brevet publié sous le n° EP-1 124 286, au nom du même déposant, qui divulgue un bornier de raccordement rapide par enfichage direct de conducteur(s) équipant des appareils électriques modulaires et comportant des moyens pour brocher ou débrocher sans outil et à tout moment ledit bornier.To facilitate connection, and in particular to overcome problems related to smallness and lack of visibility, it has been proposed that the means of connection are removable, i.e. detachable from the housing, so that the connection can be made regardless of the location of said housing. It is in particular the subject of the patent published under the number EP-1 124 286, in the name of the same Applicant, who discloses a quick connection terminal block by direct plugging in conductor (s) equipping modular electrical devices and comprising means for broaching or unhooking without tools and at any time said terminal block.

Ce bornier débrochable est au surplus équipé de moyens de guidage se développant à l'extérieur du boítier, et qui permettent - particulièrement en cas d'utilisation brochée - le guidage de l'extrémité des câbles pour les insérer dans les orifices aboutissant aux moyens de connexion rapide.This removable terminal block is furthermore equipped with guide means developing on the outside of the case, and which allow - especially in case of paperback use - guiding the end of the cables to insert them in the orifices leading to the quick connection means.

L'idée à la base de la présente invention est également de faciliter le raccordement des conducteurs, mais sans que le boítier ne présente de partie amovible, comme c'est le cas dans le brevet EP-1 124 286. A cet effet, un nouveau boítier a été créé, selon l'invention, qui améliore la visibilité en vue de faciliter l'accession aux moyens de connexion, et qui autorise de plus une modification de la direction d'insertion des câbles dans lesdits moyens pour augmenter le degré d'ergonomie de l'opération de connexion. The idea underlying the present invention is also to facilitate the connection of the conductors, but without the housing having any part removable, as is the case in patent EP-1 124 286. For this purpose, a new housing was created, according to the invention, which improves visibility with a view to facilitate access to the means of connection, and which also authorizes a modification of the direction of insertion of the cables in said means for increase the degree of ergonomics of the connection operation.

Pour remplir ces objectifs, l'invention, qui conceme un appareil électrique de type disjoncteur, bloc ou interrupteur différentiel, comportant classiquement un boítier isolant dont la façade est équipée d'un levier de commande, une semelle opposée à ladite façade étant prévue pour être montée sur un rail support normalisé, ledit boítier pouvant de plus être accolé suivant ses grandes faces latérales à des boítiers d'appareils électriques du même type et étant muni, pour son raccordement à un circuit de distribution d'électricité, de moyens de connexion d'entrée et de sortie respectivement accessibles via au moins un orifice pratiqué dans une face de raccordement connexe d'une part à la semelle et d'autre part aux faces d'accolement, se caractérise à titre essentiel en ce qu'au moins la face de raccordement dans laquelle débouchent les moyens de connexion d'entrée est constituée d'une pièce additionnelle solidarisée au boítier, comportant au moins un orifice d'introduction d'un ou plusieurs conducteurs pratiqué dans au moins une surface inclinée par rapport à la face de raccordement de telle sorte que chaque orifice soit visible et accessible dans le prolongement de la façade de l'appareil électrique.To fulfill these objectives, the invention, which relates to an electrical appliance for circuit breaker, block or differential switch type, conventionally comprising a insulating housing whose front is equipped with a control lever, a sole opposite said facade being designed to be mounted on a support rail standardized, said housing being able to be additionally attached along its large faces side to housings of electrical appliances of the same type and being provided, for its connection to an electricity distribution circuit, connection means inlet and outlet respectively accessible via at least one opening in a connection face connected on the one hand to the sole and on the other hand to the contiguous faces, is characterized in an essential way in that at least the face of connection into which the input connection means open is consisting of an additional part secured to the housing, comprising at least one orifice for introducing one or more conductors made in at least one surface inclined to the connection face so that each opening is visible and accessible in the extension of the front of the device electric.

Par rapport aux boítiers classiques, les boítiers de l'invention comportent par conséquent deux modifications majeures : un changement de l'axe d'introduction des conducteurs, et une inclinaison des faces de raccordement de telle sorte qu'elles deviennent visibles par un utilisateur placé face au tableau de distribution, c'est-à-dire face aux façades équipées des leviers de commande.Compared to conventional housings, the housings of the invention comprise by two major modifications: a change in the axis of introduction conductors, and an inclination of the connection faces so that that they become visible to a user placed in front of the distribution board, that is to say facing the facades equipped with control levers.

L'existence d'une pièce additionnelle est avantageuse en termes d'industrialisation du montage des appareils électriques. En effet, cette pièce est fixée au reste du boítier en fin de montage, ce qui offre, pendant la plus grande partie de l'assemblage, un accès aux parties sous tension permettant de réaliser des tests de fonctionnement. Cette ouverture permet de plus de faciliter le montage de certains composants qu'il faudrait autrement introduire par les orifices de connexion.The existence of an additional room is advantageous in terms industrialization of the assembly of electrical devices. Indeed, this piece is fixed to the rest of the case at the end of assembly, which offers, during the greatest part of the assembly, an access to the parts under tension allowing to realize functional tests. This opening also makes it easier to mounting certain components that would otherwise have to be introduced through the holes of connection.

Pour faciliter encore le travail de connexion des câbles, chaque orifice est prolongé par un canon de guidage dont l'axe est sensiblement perpendiculaire à la surface inclinée dans laquelle est pratiqué ledit orifice.To further facilitate the cable connection work, each hole is extended by a guide gun whose axis is substantially perpendicular to the inclined surface in which said hole is made.

Bien que tous les moyens de connexions puissent bénéficier de l'invention, celle-ci s'applique en effet particulièrement bien à des moyens de connexion dits rapides, c'est-à-dire basés sur des lames ressorts. Dans ce cas, l'orifice d'entrée des câbles à raccorder est assez restreint, et doit de préférence comporter un tel canon de guidage, pour que l'extrémité du câble puisse s'insérer dans de bonnes conditions entre la borne et la lame ressort. Le canon de guidage trouve cependant également à s'appliquer dans des configurations dans lesquelles les moyens de connexion sont à cage et à vis.Although all the connection means can benefit from the invention, this indeed applies particularly well to so-called connection means fast, i.e. based on leaf springs. In this case, the inlet port cables to be connected is quite limited, and should preferably include such guide bush, so that the end of the cable can be inserted in good conditions between the terminal and the leaf spring. The guide bush finds however also to be applied in configurations in which the means of connection are cage and screw.

Pour chaque phase ou le neutre, il peut y avoir plusieurs possibilités de connexion. Pour améliorer encore les possibilités de guidage, il a été prévu, selon l'invention, que le nombre d'orifices corresponde au nombre d'unités de moyens de connexions.For each phase or the neutral, there can be several possibilities of connection. To further improve the guidance possibilities, according to the invention, that the number of orifices corresponds to the number of units of means of connections.

Pour différencier la phase et le neutre, outre parfois l'existence d'un marquage en couleurs, les boítiers comportent en général des niveaux de pontages distincts, et donc des positionnements différents des moyens de connexion. Ainsi, dans l'invention, la pièce additionnelle peut comporter plusieurs surfaces inclinées, mais décalées l'une par rapport à l'autre pour différencier la zone d'introduction par exemple des conducteurs de phase de celle des conducteurs de neutre.To differentiate the phase and the neutral, in addition to sometimes the existence of a marking in color, the boxes generally have separate bridging levels, and therefore different positions of the connection means. So in the invention, the additional part may have several inclined surfaces, but offset from each other to differentiate the introduction area by example of phase conductors from that of neutral conductors.

La réalisation de la connexion, vue de l'utilisateur, se fait exactement de la même manière, seul change le plan d'introduction du câble dans l'orifice de connexion, qui subit un décalage.The connection, seen from the user, is done exactly from the same way, only changes the plane of introduction of the cable into the orifice of connection, which is lagged.

Dans l'hypothèse où les moyens de raccordement sont à lame ressort, ils permettent un enfichage direct des conducteurs, de préférence rigides, qui s'insèrent entre la borne et la lame précontrainte. Ce mode de connexion nécessite cependant l'utilisation d'un moyen d'allègement de la contrainte du ressort pour pouvoir libérer les câbles. Cela peut être fait en intégrant un bouton au boítier, qui vient exercer une contrainte supplémentaire sur le ressort en vue de ladite libération. Alternativement, cette libération peut également être effectuée par un outil du type tournevis, c'est-à-dire muni d'une tige permettant d'exercer une telle action supplémentaire sur la lame ressort.In the event that the connection means are leaf spring, they allow direct insertion of conductors, preferably rigid, which fit between the terminal and the pre-stressed blade. This connection mode requires however the use of a means of lightening the stress of the spring to ability to release cables. This can be done by integrating a button into the housing, which comes to exert an additional stress on the spring in view of said release. Alternatively, this release can also be carried out by a tool of the screwdriver type, that is to say provided with a rod allowing to exercise such a additional action on the leaf spring.

A cet effet, selon une possibilité, chaque orifice d'introduction est surmonté d'un conduit de passage d'un outil apte à déplacer la lame ressort pour libérer le conducteur enfiché.To this end, according to one possibility, each insertion orifice is surmounted by a conduit for passage of a tool capable of moving the leaf spring to release the conductor inserted.

Dans la pièce additionnelle, sur son côté interne, chaque lame ressort est de préférence disposée entre des nervures prolongeant vers l'intérieur le canon de guidage et s'étendant sensiblement parallèlement aux grandes faces latérales du boítier.In the additional room, on its internal side, each leaf spring is preferably arranged between ribs extending inward the barrel of guiding and extending substantially parallel to the large lateral faces of the housing.

Ces nervures visent notamment à séparer et isoler les différentes lames ressorts situées au même niveau de pontage pour une même surface inclinée. En l'absence de pièce additionnelle, il faudrait procéder au montage d'éléments séparateurs via les orifices de connexion, ce qui est industriellement beaucoup moins favorable.These ribs aim in particular to separate and isolate the different blades springs located at the same bridging level for the same inclined surface. In the absence of additional room, it would be necessary to assemble elements separators via the connection holes, which is industrially very much less favorable.

Selon une possibilité, la pièce additionnelle est clipsable sur le boítier de l'appareil électrique.According to one possibility, the additional part can be clipped onto the housing. the electrical appliance.

Aux fins de permettre ce clipsage, ladite pièce comporte, au moins à ses extrémités supérieure et inférieure, des pattes à extrémité unciforme venant se clipser élastiquement dans des logements ou ouvertures prévues à cet effet dans le boítier.In order to allow this clipping, said part comprises, at least at its upper and lower ends, legs with a uniform end coming from clip elastically into housings or openings provided for this purpose in The box.

Cette pièce clipsable peut en réalité être vue comme un capot qui vient fermer le boítier, notamment sur sa face de raccordement d'entrée. Elle peut également comporter une portion d'allure parallèle à la façade, constituant une partie de cette dernière, dont l'extrémité libre comporte des pattes flexibles prévues pour se clipser dans le boítier.This clip-on piece can actually be seen as a cover that comes to close the housing, especially on its input connection face. She can also have a portion of appearance parallel to the facade, constituting part of this last, the free end of which has flexible legs provided for clip into the housing.

Dans ce dernier cas, le capot constitué de cette pièce recouvre par conséquent au moins une partie de deux surfaces connexes, la face de raccordement et une partie de la façade.In the latter case, the cover made up of this part therefore covers at least part of two connected surfaces, the connecting face and a part of the facade.

Alternativement au clipsage, ladite pièce additionnelle peut être fixée au boítier par exemple par collage et/ou par soudage.As an alternative to clipping, said additional part can be fixed to the housing. for example by gluing and / or welding.

Selon une possibilité, la portion de la pièce additionnelle constituant une partie de la façade comporte au moins un orifice de contrôle de la présence de tension. Elle peut également être munie d'une rainure de calibrage de la longueur de dénudage du conducteur à connecter.According to one possibility, the portion of the additional part constituting a part of the facade comprises at least one orifice for checking the presence of voltage. It can also be fitted with a length calibration groove stripping of the conductor to be connected.

Tout boítier comportant sur au moins une de ses faces de raccordement une face inclinée selon l'invention permet au monteur électricien ou à l'utilisateur de réaliser des connexions électriques avec un confort optimal, ce qui procure notamment un gain de rapidité au montage conférant au produit un avantage économique indéniable.Any case comprising on at least one of its connection faces a inclined face according to the invention allows the electrician or the user to make electrical connections with optimal comfort, which provides in particular a gain in speed of assembly giving the product an advantage undeniable economic.

L'invention va à présent être décrite plus en détail, en référence aux figures annexées, pour lesquelles :

  • la figure 1 est une coupe longitudinale, côté phase, d'une portion de disjoncteur comportant des moyens de connexion d'entrée à lame ressort, et muni d'une pièce additionnelle à surface(s) inclinée(s) selon l'invention ;
  • la figure 2 est une vue en coupe longitudinale, côté neutre, de la même portion dudit disjoncteur ;
  • la figure 3 est une vue en perspective du côté externe d'une pièce à surfaces inclinées comportant deux orifices d'insertion et deux orifices de déconnexion, respectivement pour la phase et pour le neutre ;
  • la figure 4 montre le côté interne d'une pièce additionnelle ; et
  • la figure 5 constitue une vue en perspective d'un disjoncteur phase-neutre muni d'une pièce selon l'invention.
The invention will now be described in more detail, with reference to the appended figures, for which:
  • Figure 1 is a longitudinal section, phase side, of a circuit breaker portion having input connection means with leaf spring, and provided with an additional part with inclined surface (s) according to the invention;
  • Figure 2 is a longitudinal sectional view, neutral side, of the same portion of said circuit breaker;
  • Figure 3 is a perspective view of the outer side of a part with inclined surfaces having two insertion holes and two disconnection holes, respectively for the phase and for the neutral;
  • Figure 4 shows the internal side of an additional part; and
  • Figure 5 is a perspective view of a phase-neutral circuit breaker provided with a part according to the invention.

En référence à la figure 1, la partie du boítier visible montre la façade (F) du disjoncteur, la face (C) dans laquelle débouchent les moyens de connexion, ainsi que la semelle (S) permettant la fixation du boítier aux rails. La façade (F) présente elle-même deux niveaux, une manette de commande (non représentée) dépassant du niveau le plus élevé.Referring to Figure 1, the visible part of the case shows the front (F) of the circuit breaker, the face (C) into which the connection means open, thus as the sole (S) for fixing the housing to the rails. The facade (F) presents itself two levels, a control lever (not shown) exceeding the highest level.

Selon l'invention, une pièce (P) équipe la face (C) et, en l'occurrence, le niveau le plus bas de la façade (F). Cette pièce présente un orifice (1) donnant accès à une lame ressort (2) via un canon de guidage (3). Elle est surmontée d'un second orifice (4) donnant accès à un conduit (5) débouchant également sur la lame ressort (2). La fonction des deux orifices (1, 4) et des conduits (3, 5) correspondants n'est évidemment pas identique.According to the invention, a part (P) equips the face (C) and, in this case, the level the bottom of the facade (F). This part has an orifice (1) giving access to a leaf spring (2) via a guide barrel (3). It is surmounted by a second orifice (4) giving access to a conduit (5) also opening onto the leaf spring (2). The function of the two orifices (1, 4) and the corresponding conduits (3, 5) is not obviously not identical.

Le couple orifice (1) / canon de guidage (3) permet l'accès à l'extrémité libre (6) de la lame ressort (2). Cette extrémité libre est précontrainte en appui contre une borne électrique (7) de l'appareil électrique. Le canon de guidage (3) permet d'orienter et de guider l'extrémité libre d'un conducteur de telle sorte que celle-ci puisse s'insérer entre la borne (7) et l'extrémité (6) de la lame ressort (2), pour réaliser une connexion électrique avec les moyens de connexion ainsi constitués.The orifice (1) / guide barrel (3) couple allows access to the free end (6) of the leaf spring (2). This free end is prestressed in abutment against a electrical terminal (7) of the electrical appliance. The guide barrel (3) allows to orient and guide the free end of a conductor so that it can be inserted between the terminal (7) and the end (6) of the leaf spring (2), to make an electrical connection with the connection means thus formed.

Le couple orifice (4) / conduit (5) permet l'insertion d'un outil allongé, de type tournevis, permettant de libérer la contrainte exercée par la lame ressort (2) sur le conducteur, ce qui est obtenu en exerçant une contrainte supplémentaire sur ladite lame ressort (2).The orifice (4) / conduit (5) couple allows the insertion of an elongated tool, of the type screwdriver, to release the stress exerted by the leaf spring (2) on the conductor, which is achieved by exerting additional stress on said leaf spring (2).

La borne (7) est reliée, via une tresse conductrice (8), à une bilame (9) permettant, via une serrure, d'écarter le contact mobile du contact fixe en cas de surintensité, selon une mise en oeuvre bien connue en soi, et qui ne sera pas davantage expliquée dans le cadre de la présente description.The terminal (7) is connected, via a conductive braid (8), to a bimetallic strip (9) allowing, via a lock, to move the movable contact from the fixed contact in the event of overcurrent, according to an implementation well known in itself, and which will not further explained in the context of this description.

Selon un aspect essentiel de l'invention, les orifices (1 et 4) sont pratiqués dans une surface inclinée (I) de la pièce (P), qui présente une inclinaison de l'ordre de 45° par exemple par rapport à la façade (F), de telle sorte que ces orifices (1, 4) soient visibles par un utilisateur qui regarde dans la direction de la flèche (A). Cette surface (I), du fait de son inclinaison, est visible dans le prolongement direct de ladite façade (F), et l'opération de connexion / déconnexion d'un conducteur dans/de l'appareil électrique est immédiate et aisée pour l'utilisateur.According to an essential aspect of the invention, the orifices (1 and 4) are made in an inclined surface (I) of the part (P), which has an inclination of the order of 45 ° for example with respect to the facade (F), so that these orifices (1, 4) are visible to a user looking in the direction of the arrow (A). This surface (I), due to its inclination, is visible in the direct extension of said front (F), and the operation of connecting / disconnecting a conductor in / from the electrical appliance is immediate and easy for the user.

En l'espère, la pièce (P) se prolonge en façade du produit et se fixe au niveau de l'épaulement marquant la surélévation de la façade (F), à l'aide de crochets unciformes (19) équipant son extrémité libre, qui viennent se clipser dans des orifices situés à la base dudit épaulement.In the hope, the part (P) extends in front of the product and is fixed at the level of the shoulder marking the elevation of the facade (F), using hooks unciforms (19) equipping its free end, which are clipped into holes located at the base of said shoulder.

D'autres crochets (non visibles sur cette figure) permettent de réaliser la fixation par clipsage dans la partie basse de l'appareil, c'est-à-dire au voisinage de la semelle (S).Other hooks (not visible in this figure) allow the fixing to be carried out by clipping in the lower part of the device, i.e. in the vicinity of the sole (S).

En référence à la figure 2, la même pièce (P), sectionnée du côté neutre, comporte une seconde surface inclinée (I') décalée par rapport à la première surface (I) et à la façade (F) de telle sorte qu'une différentiation oculaire puisse être effectuée entre le côté phase et le côté neutre. Cette surface inclinée (I') se développe en prolongation de la partie inférieure d'une surface d'allure verticale (18).With reference to FIG. 2, the same part (P), sectioned on the neutral side, has a second inclined surface (I ') offset from the first surface (I) and facade (F) so that an ocular differentiation can be performed between the phase side and the neutral side. This inclined surface (I ') is develops in extension of the lower part of a vertical-looking surface (18).

Comme en figure 1, pour chaque lame ressort (12), dont l'extrémité (16) est contrainte en appui contre la borne (17), s'ouvrent deux orifices (10 et 14) respectivement prolongés par un canon de guidage (13) et un conduit (15) de manière à pouvoir permettre la connexion / déconnexion de l'extrémité dénudée d'un conducteur rigide.As in Figure 1, for each leaf spring (12), the end (16) of which is constraint pressing against the terminal (17), two openings (10 and 14) open respectively extended by a guide barrel (13) and a conduit (15) of so as to allow connection / disconnection of the stripped end of a rigid conductor.

En figure 2, une patte de fixation (19') de la pièce (P) apparaít en partie inférieure de celle-ci, ladite patte (19') venant se clipser dans un logement (20) équipant le boítier.In Figure 2, a fixing lug (19 ') of the part (P) appears in part lower of the latter, said tab (19 ') being clipped into a housing (20) equipping the case.

Les pattes de clipsage supérieures (19) apparaissent également en figure 3, dans le prolongement de la partie de la pièce (P) qui constitue une portion de façade (F). Cette portion comporte également des orifices (21, 21') de contrôle de la présence de tension dans l'appareil.The upper clip tabs (19) also appear in FIG. 3, in the extension of the part of the part (P) which constitutes a portion of front (F). This portion also includes orifices (21, 21 ') for controlling the presence of voltage in the device.

Cette figure 3 montre clairement le décalage entre les surfaces inclinées (I et I') dans lesquelles il est possible d'insérer plusieurs orifices (1, 1' ; 10, 10') d'insertion des câbles, correspondant chacun à une lame ressort (2, 12) disposée à l'intérieur du boítier de l'appareil. A chacun de ces orifices correspondent bien entendu des orifices de déconnexion (4, 4' ; 14, 14').This figure 3 clearly shows the offset between the inclined surfaces (I and I ') in which it is possible to insert several insertion holes (1, 1 '; 10, 10') cables, each corresponding to a leaf spring (2, 12) arranged inside from the camera body. Each of these orifices corresponds of course to disconnection holes (4, 4 '; 14, 14').

Comme cela ressort de la figure 4, les orifices externes (10, 10') se prolongent par des canons de guidage (13, 13') et, les orifices (14, 14') se prolongent par des conduits (15, 15'). Les canons (13, 13') et les conduits (14, 14') débouchent au niveau d'une lame ressort (2) en l'occurrence partiellement double, dont les deux lamelles sont séparées par des nervures (22).As shown in Figure 4, the external holes (10, 10 ') extend by guide barrels (13, 13 ') and, the orifices (14, 14') are extended by conduits (15, 15 '). The barrels (13, 13 ') and the conduits (14, 14') open at level of a leaf spring (2) in this case partially double, both of which slats are separated by ribs (22).

La pièce (P) forme un capot constituant, comme cela apparaít clairement en figure 5, la face (C) du boítier, ainsi qu'une partie de la façade (F), partie qui se termine à la base de l'épaulement contenant la manette de commande.The part (P) forms a constituent cover, as is clearly seen in Figure 5, the face (C) of the housing, as well as part of the front (F), part which ends at the base of the shoulder containing the control handle.

Au voisinage de l'orifice de contrôle (21) se situe une cale de dénudage (23) donnant la mesure de la longueur de dénudage appropriée pour une bonne connexion.In the vicinity of the control orifice (21) is located a stripping shim (23) giving the measurement of the appropriate stripping length for good connection.

D'autres possibilités de configuration sont bien entendu possibles, selon la nature de l'appareil modulaire auquel ces pièces (P) sont fixées. Il peut ainsi y avoir plus d'orifices (1, 10), n'y avoir qu'une seule surface inclinée qui fait la totalité de la largeur de la pièce, etc. La description ci-dessus, en référence aux figures, ne concerne dès lors qu'un exemple possible de mise en oeuvre de l'invention, l'homme de l'art pouvant adapter cette pièce en fonction notamment des variantes précitées.Other configuration possibilities are of course possible, depending on the nature of the modular device to which these parts (P) are attached. So there can be more orifices (1, 10), having only one inclined surface which makes up the entire width of the room, etc. The above description, with reference to the figures, does not therefore relates to a possible example of implementation of the invention, the person skilled in the art can adapt this part according in particular to the variants above.
