Description

La présente invention concerne un dispositif de protection des éléments emboîtables d'un connecteur.The present invention relates to a device for protecting the nestable elements of a connector.

ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

On sait que le nettoyage d'un connecteur encrassé de boue est difficile en raison d'un accès très restreint à certaines parties du connecteur. La boue s'oppose au fonctionnement mécanique et électrique du connecteur.It is known that cleaning a dirty mud connector is difficult because of very limited access to certain parts of the connector. The sludge is opposed to the mechanical and electrical operation of the connector.

Afin de protéger les éléments emboîtables d'un connecteur contre la boue, que celle-ci soit projetée sur l'élément de connecteur ou que l'élément de connecteur trempe dans la boue, il a été proposé de mettre en place un bouchon sur l'élément de connecteur ou de réaliser, comme dans le connecteur du document de brevet US5722842 , un piston incorporé à l'élément de connecteur et rappelé par un ressort dans une position dans laquelle le piston entoure les organes de connexion de l'élément de connecteur de façon à remplir l'espace entre les organes de connexion et empêcher ainsi la boue de pénétrer entre les organes de connexion.In order to protect the interlocking elements of a connector against the sludge, whether it is projected onto the connector element or that the connector element soaks in the sludge, it has been proposed to place a plug on the sludge. connector element or realize, as in the connector of the patent document US5722842 a piston incorporated in the connector member and biased by a spring in a position in which the piston surrounds the connecting members of the connector member so as to fill the space between the connecting members and thereby prevent sludge to penetrate between the connecting members.

Ces dispositifs ne sont pas satisfaisants. En effet, lorsqu'un bouchon est utilisé pour protéger un élément de connecteur, le bouchon doit être retiré lors de l'utilisation de l'élément de connecteur pour un raccordement à un autre élément de connecteur. Il existe le risque que l'utilisateur oublie ou omette, par manque de temps, de remettre le bouchon en place. Le bouchon risque en outre d'être égaré ou, s'il est attaché à l'élément de connecteur, il risque de recevoir de la boue ou de tomber dans la boue, de sorte qu'il n'est plus possible de refermer l'élément de connecteur avec le bouchon. Dans le cas d'un piston, la boue risque de s'accumuler dans les interstices entre les organes de connexion et le piston de sorte qu'il devient rapidement impossible de manoeuvrer le piston et donc de dégager des organes de connexion. Les systèmes à piston ont l'inconvénient d'être complexes et de nécessiter une relativement grande longueur de connecteur rendant ce dernier plus difficile à implanter en cas de montage sur une paroi d'un équipement par exemple.These devices are not satisfactory. Indeed, when a plug is used to protect a connector member, the plug must be removed when using the connector member for connection to another connector member. There is the risk that the user forgets or omits, for lack of time, to put the cap back in place. In addition, the plug may be mislaid or, if attached to the connector element, it may receive mud or fall into the mud, so that it can no longer be closed. connector element with the plug. In the case of a piston, the sludge may accumulate in the interstices between the connecting members and the piston so that it quickly becomes impossible to maneuver the piston and thus to disengage connecting members. Piston systems have the disadvantage of being complex and requiring a relatively long length of connector makes the latter more difficult to implement in case of mounting on a wall of equipment for example.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Un but de l'invention est de proposer un dispositif de protection relativement compact, facilement manipulable et assurant une protection efficace.An object of the invention is to provide a relatively compact protective device, easily manipulated and providing effective protection.

RESUME DE L'INVENTIONSUMMARY OF THE INVENTION

En vue de la réalisation de ce but, on propose selon l'invention un dispositif de protection d'un connecteur comportant deux éléments de connecteur pourvus d'extrémités ouvertes emboîtables l'une dans l'autre selon une direction d'engagement, le dispositif comportant un premier obturateur et un deuxième obturateur reliés chacun à une des extrémités ouvertes par une articulation déportée latéralement et d'axe parallèle à la direction d'engagement de telle manière que chaque obturateur soit mobile en rotation entre une position d'obturation et une position de dégagement de l'extrémité ouverte concernée, les obturateurs ayant une face frontale pourvue de moyens de leur solidarisation mutuelle en rotation autour de l'axe d'articulation et l'articulation du premier obturateur étant montée sur l'extrémité concernée pour être mobile en translation parallèlement à la direction d'engagement entre une position affleurant l'extrémité ouverte et une position en retrait de l'extrémité ouverte.With a view to achieving this object, the invention proposes a device for protecting a connector comprising two connector elements provided with open ends that are nestable into one another in a direction of engagement, the device comprising a first shutter and a second shutter each connected to one of the open ends by a laterally offset articulation and of axis parallel to the direction of engagement so that each shutter is rotatable between a shutter position and a position release of the open end concerned, the shutters having a front face provided with means for their mutual mutual attachment in rotation about the axis of articulation and the articulation of the first shutter being mounted on the end concerned to be movable in translation parallel to the direction of engagement between a position flush with the open end and a retracted position it's open end.

Les obturateurs sont solidarisés en rotation préalablement à l'engagement en amenant leurs faces frontales en contact et peuvent être pivotés simultanément immédiatement avant l'engagement. Le dégagement des obturateurs intervient donc alors que les extrémités ouvertes sont séparées d'une distance égale aux épaisseurs cumulées des obturateurs et pour un temps très court, limitant le risque que des saletés ne pénètrent dans les extrémités ouvertes des éléments de connecteurs. Le déplacement du premier obturateur dans sa position en retrait permet l'engagement puis l'emboîtement des extrémités ouvertes des éléments de connecteur l'une dans l'autre. Ainsi, l'obturateur reste en permanence attaché à l'élément de connecteur qu'il protège et ne risque donc pas d'être perdu, et son ouverture est effectuée au moment de l'emboîtement avec un autre élément de connecteur.The shutters are secured in rotation prior to engagement by bringing their front faces into contact and can be rotated simultaneously immediately before engagement. The release of the shutters therefore occurs while the open ends are separated by a distance equal to the cumulative thicknesses of the shutters and for a very short time, limiting the risk of dirt getting into the ends open connector elements. The displacement of the first shutter in its retracted position allows the engagement and then the engagement of the open ends of the connector elements into one another. Thus, the shutter remains permanently attached to the connector element that it protects and therefore not likely to be lost, and its opening is performed at the time of nesting with another connector element.

Selon une version avantageuse de l'invention, le dispositif comprend au moins un organe de rappel de chacun des obturateurs en position d'obturation.According to an advantageous version of the invention, the device comprises at least one return member of each of the shutters in the closed position.

Les obturateurs sont ainsi ramenés dans leur position d'obturation dès la déconnexion réalisée.The shutters are thus returned to their closed position as soon as the disconnection is completed.

De préférence alors, l'organe de rappel du premier obturateur est un ressort hélicoïdal monté pour travailler en compression de manière à ramener l'obturateur de la position en retrait vers la position affleurante et en torsion de manière à ramener l'obturation de sa position de dégagement vers sa position d'obturation.Preferably then, the first shutter return member is a helical spring mounted to work in compression so as to return the shutter from the recessed position to the flush and torsion position so as to return the shutter to its position clearance to its closed position.

Le ressort assure alors deux fonctions une fonction de rappel en pivotement et une fonction de rappel en translation.The spring then provides two functions a function of return pivoting and a function of return in translation.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

En référence aux figures 1 à 7, le dispositif de protection selon l'invention est destiné à protéger un connecteur comportant deux éléments de connecteur emboîtables 1 et 2. Dans le mode de réalisation illustré, l'élément de connecteur 2 comporte une douille cylindrique de section circulaire 4 qui est destinée à être fixée à l'extrémité d'un câble et qui contient un organe de connexion 5 comprenant des trous métallisés 6 reliés à des fils de liaison. L'élément de connecteur 1 comporte une douille cylindrique de section circulaire 7 qui est destinée à être montée à l'extrémité d'un câble et qui contient un organe de connexion 8 équipé de broches 9 en coïncidence avec les trous métallisés 6.With reference to Figures 1 to 7 , the protection device according to the invention is intended to protect a connector having two interlocking connector elements 1 and 2. In the illustrated embodiment, the connector element 2 comprises a cylindrical sleeve of circular section 4 which is intended to be attached to the end of a cable and which contains a connection member 5 comprising metallized holes 6 connected to the connecting son. The connector element 1 comprises a cylindrical sleeve of circular section 7 which is intended to be mounted at the end of a cable and which contains a connection member 8 equipped with pins 9 in register with the metallized holes 6.

Les éléments de connecteurs 1, 2 comportent tout deux un manchon 10, 20 cylindrique ayant une extrémité ouverte s'étendant en saillie respectivement des orifices d'entrée des trous métallisés 6 et des extrémités libres des broches 9. Les manchons 10, 20 sont agencés pour pouvoir être emboîtés l'un dans l'autre selon une direction d'engagement de manière à permettre la pénétration des broches 9 dans les trous métallisés 6.The connector elements 1, 2 both comprise a cylindrical sleeve 10, having an open end projecting respectively from the inlet openings of the metallized holes 6 and the free ends of the pins 9. The sleeves 10, 20 are arranged to can being nested one inside the other in a direction of engagement so as to allow the pins 9 to penetrate the metallized holes 6.

Les extrémités ouvertes des manchons 10 et 20 sont pourvues d'un obturateur 11, 21 respectivement, de forme discoïdale, relié au manchon 10, 20 par une articulation, généralement désignée en 12, 22, déportée latéralement et d'axe parallèle à la direction d'engagement.The open ends of the sleeves 10 and 20 are provided with a shutter 11, 21 respectively, of disc shape, connected to the sleeve 10, 20 by a hinge, generally designated 12, 22, offset laterally and of axis parallel to the direction. commitment.

L'articulation 12, 22 comprend ici un pion 13, 23 cylindrique s'étendant depuis un bord de l'obturateur 11, 21 parallèlement à une direction normale à celui-ci. Le pion 13, 23 est reçu à pivotement dans une gouttière 14, 24 s'étendant le long d'un côté du manchon 10, 20 de sorte que l'obturateur 11, 21 puisse pivoter entre une position d'obturation et une position de dégagement de l'extrémité ouverte du manchon 10, 20. La gouttière 14, 24 reçoit un ressort 15, 25 de rappel de l'obturateur 11, 21 en position d'obturation. Dans leur position d'obturation, les obturateurs 11, 21 sont en contact et en frottement avec le manchon 10, 20 correspondant.The hinge 12, 22 here comprises a cylindrical pin 13, 23 extending from an edge of the shutter 11, 21 parallel to a direction normal thereto. The pin 13, 23 is pivotally received in a channel 14, 24 extending along one side of the sleeve 10, 20 so that the shutter 11, 21 can be pivoted between a closed position and a closed position. release of the open end of the sleeve 10, 20. The channel 14, 24 receives a spring 15, 25 of the shutter 11, 21 in the closed position. In their closed position, the shutters 11, 21 are in contact and in friction with the sleeve 10, 20 corresponding.

La gouttière 14 reçoit en outre le pion 13 à coulissement parallèlement à la direction d'engagement entre une position affleurant l'extrémité ouverte du manchon 10 et une position en retrait de cette extrémité ouverte selon une course au moins égale à la longueur d'emboîtement des éléments de connecteur 1, 2 nécessaire à la connexion de ceux-ci, l'obturateur 11 étant pivoté en position de dégagement.The gutter 14 further receives the pin 13 sliding parallel to the direction of engagement between a position flush with the open end of the sleeve 10 and a position recessed from this open end in a race at least equal to the interlocking length connector elements 1, 2 necessary for the connection thereof, the shutter 11 being rotated in the disengaged position.

Les obturateurs 11, 21 ont des faces frontales 16, 26 pourvues de reliefs 17, 27 de formes réciproques pour assurer leur solidarisation en pivotement autour de l'axe de l'articulation 12, 22 lorsque les faces frontales 16, 26 sont en contact. Les reliefs 17, 27 sont ici respectivement un doigt avec un méplat en saillie de la face frontale 16 et un logement de forme correspondante ménagé dans la face frontale 26. Ceci permet d'assurer un détrompage obligeant à aligner les axes des articulations pour permettre le pivotement des obturateurs. Ceci permet également d'aligner les éléments de connecteurs l'un avec l'autre préalablement à la connexion proprement dite.The shutters 11, 21 have end faces 16, 26 provided with reliefs 17, 27 of reciprocating shapes to ensure their integral pivoting about the axis of the hinge 12, 22 when the end faces 16, 26 are in contact. The reliefs 17, 27 are here respectively a finger with a flat surface projecting from the end face 16 and a housing of corresponding shape. provided in the front face 26. This ensures a keying forcing to align the axes of the joints to allow the pivoting of the shutters. This also allows to align the connector elements with each other prior to the actual connection.

L'obturateur 21 comprend en outre un ergot latéral 28 facilitant sa manipulation pour l'entraîner en pivotement de sa position d'obturation vers sa position de dégagement. En variante, l'obturateur peut comprendre plusieurs ergots latéraux ou une surface moletée ou cannelée.The shutter 21 further comprises a lateral lug 28 facilitating its manipulation to cause it to pivot from its closed position to its disengaged position. Alternatively, the shutter may include a plurality of lateral lugs or a knurled or fluted surface.

Comme illustré par la figure 4, lorsque les éléments de connecteur 1 et 2 sont séparés, les manchons 10 et 20 sont fermés de façon étanche par les obturateurs 11, 21. Lorsque l'on souhaite réaliser un emboîtement des éléments de connecteur 1, 2, les faces frontales 16, 26 des obturateurs 11, 21 en position d'obturation sont présentées en regard l'une de l'autre pour engager le doigt 17 dans le logement 27 en mettant les faces frontales 16, 26 en contact et en faisant coïncider les axes des articulations 12, 22. L'ergot 28 est ensuite manipulé pour faire pivoter l'obturateur 21 vers sa position de dégagement en entraînant l'obturateur 11 dans cette même position par la coopération des reliefs 17, 27 solidarisant les obturateurs 11, 21 (figure 5). Un mouvement de rapprochement des éléments de connecteur 1, 2 provoque l'engagement et l'emboîtement des manchons 10, 20 l'un dans l'autre, la pénétration des broches 9 dans les trous métallisés 6 et le coulissement du pion 13 dans la goulotte 14 amenant l'obturateur 11 dans sa position en retrait de manière que celui-ci ne gêne pas la connexion (figure 6). On notera que l'obturateur 21 (maintenant solidaire de l'obturateur 11) fournit un appui pour un doigt de l'opérateur facilitant l'introduction des manchons l'un dans l'autre et permettant l'exercice de l'effort d'emboîtement des éléments de connecteur. De préférence, les surfaces internes et externes des éléments de connecteurs 1, 2 et des composants qui leur sont attachés ont des coefficients de frottement favorisant leurs glissements relatifs.As illustrated by figure 4 when the connector elements 1 and 2 are separated, the sleeves 10 and 20 are sealed by the shutters 11, 21. When it is desired to engage the connector elements 1, 2, the end faces 16, 26 shutters 11, 21 in the closed position are presented opposite one another to engage the finger 17 in the housing 27 by putting the end faces 16, 26 in contact and coinciding the axes of the joints 12 22. The pin 28 is then manipulated to pivot the shutter 21 towards its release position by driving the shutter 11 in this same position by the cooperation of the reliefs 17, 27 solidarisant the shutters 11, 21 ( figure 5 ). A movement of approximation of the connector elements 1, 2 causes engagement and engagement of the sleeves 10, 20 one into the other, the penetration of the pins 9 into the plated holes 6 and the sliding of the pin 13 in the chute 14 bringing the shutter 11 in its recessed position so that it does not interfere with the connection ( figure 6 ). Note that the shutter 21 (now secured to the shutter 11) provides support for a finger of the operator facilitating the introduction of the sleeves one in the other and allowing the exercise of the interlocking force of the connector elements. Preferably, the inner and outer surfaces of the connector members 1, 2 and the components attached thereto have coefficients of friction promoting their relative sliding.

On notera qu'il est important que lorsque les axes de rotation sont concourants, les manchons, de même que les broches et les trous, soient également alignés. Cette contrainte est respectée lors de la fabrication des manchons et de leur réalisation ou montage sur les éléments de connecteur.Note that it is important that when the axes of rotation are concurrent, the sleeves, as well as the pins and holes, are also aligned. This constraint is respected during the manufacture of the sleeves and their production or mounting on the connector elements.

Lors de la séparation des éléments de connecteur 1, 2, les obturateurs 11, 21 sont rappelés vers leur position d'obturation par les ressorts 15, 25. On notera que le ressort 15 assure d'abord le rappel de l'obturateur 11 en translation vers sa position affleurante puis en rotation vers sa position d'obturation. Le ressort 25 assure uniquement le rappel en rotation de l'obturateur 21 vers sa position d'obturation.During the separation of the connector elements 1, 2, the shutters 11, 21 are returned to their closed position by the springs 15, 25. It will be noted that the spring 15 first ensures the return of the shutter 11 by translation to its flush position and then rotated to its closed position. The spring 25 provides only the return in rotation of the shutter 21 to its closed position.

On notera que la gouttière 14 a une extrémité très en retrait de l'extrémité ouverte du manchon 10 pour permettre le recul de l'obturateur 11 dans sa position en retrait. Il serait également possible de prévoir une rainure dans la gouttière 14 à l'opposé du manchon 10 pour permettre le passage de la partie reliant l'obturateur 11 au doigt 13 et celle reliant l'obturateur 21 au doigt 23 lors de la connexion.Note that the channel 14 has a very recessed end of the open end of the sleeve 10 to allow the retraction of the shutter 11 in its retracted position. It would also be possible to provide a groove in the channel 14 opposite the sleeve 10 to allow the passage of the portion connecting the shutter 11 to the finger 13 and that connecting the shutter 21 to the finger 23 during the connection.

Une butée non visible sur les figures empêche l'obturateur 11 d'être décollé de l'extrémité ouverte du manchon 10 sous l'action du ressort 15.A stop not visible in the figures prevents the shutter 11 from being detached from the open end of the sleeve 10 under the action of the spring 15.

De préférence, les obturateurs 11, 21 ont une surface opposée à la surface frontale 16, 26 pourvue d'élément d'étanchéité déformables pour rendre étanche leur contact avec le manchon 10, 20.Preferably, the shutters 11, 21 have a surface opposite to the front surface 16, 26 provided with deformable sealing element to make their contact with the sleeve 10, 20 tight.

En référence plus particulièrement à la figure 7, l'obturateur 21 comprend un disque 30 en matière plastique rigide sur lequel est fixé un élément d'étanchéité 29 de forme discoidale à bord biseauté en élastomère souple. L'élément d'étanchéité 29 assure ainsi également le centrage de l'obturateur 21 sur le manchon 20. L'élément d'étanchéité 29 est représenté uniquement sur la figure 7 pour ne pas alourdir les figures 1 à 6. En variante, l'élément d'étanchéité peut être un joint torique ou avoir une forme hémisphérique aplatie.With particular reference to the figure 7 , the shutter 21 comprises a disc 30 made of rigid plastic material on which is fixed a sealing element 29 of discoidal shape with beveled edge flexible elastomer. The sealing element 29 thus also ensures the centering of the shutter 21 on the sleeve 20. The sealing element 29 is represented only on the figure 7 so as not to burden Figures 1 to 6 . Alternatively, the sealing member may be an O-ring or have a flattened hemispherical shape.

Les obturateurs peuvent en outre être rigides ou semi rigides en étant constitués par exemple d'un élastomère ou tout autre matériau non fragile.The shutters may also be rigid or semi-rigid, consisting for example of an elastomer or any other non-brittle material.

En variante, comme représenté sur les figures 8 et 9, un élément de connecteur 100 comporte une embase 3 destinée à être fixée sur une paroi d'un appareil non représenté et une douille cylindrique de section circulaire qui est fixée à l'embase 3 et qui contient un organe de connexion comprenant des trous métallisés reliés à des fils de liaison.Alternatively, as shown on the Figures 8 and 9 , a connector element 100 comprises a base 3 intended to be fixed on a wall of a device not shown and a cylindrical bushing of circular section which is fixed to the base 3 and which contains a connecting member comprising connected metallized holes to connecting wires.

L'élément de connecteur 100 comprend un manchon 110 pourvu d'un obturateur 111 relié au manchon 110 par une articulation 112 comportant un pion 113 reçu à pivotement et coulissement dans une gouttière 114 s'étendant le long du manchon 110 et recevant un ressort de rappel 115. Les composants 110, 111, 112, 113, 114 et 115 fonctionnent de la même manière que les composants 10, 11, 12, 13, 14 et 15. La gouttière 114 comprend une rainure longitudinale 116 pour recevoir à coulissement la partie 117 reliant rigidement l'obturateur 111 au pion 113. Ceci permet à la goulotte 114 d'avoir une relativement grande longueur de guidage du pion 113.The connector element 100 comprises a sleeve 110 provided with a shutter 111 connected to the sleeve 110 by a hinge 112 comprising a pin 113 pivotally and slidably received in a channel 114 extending along the sleeve 110 and receiving a spring. 115. The components 110, 111, 112, 113, 114 and 115 operate in the same way as the components 10, 11, 12, 13, 14 and 15. The channel 114 comprises a longitudinal groove 116 for slidingly receiving the part 117 rigidly connecting the shutter 111 to the pin 113. This allows the chute 114 to have a relatively long guide length of the pin 113.

L'élément de connecteur 100 est agencé pour coopérer avec un élément de connecteur du type de l'élément de connecteur 200 qui comprend une douille contenant un élément de connexion pourvue de broches pour être engagées dans les trous métallisés.The connector member 100 is arranged to cooperate with a connector member of the type of the connector member 200 which includes a socket containing a connecting element provided with pins for engagement with the plated holes.

Un manchon 120 entoure la douille. Le manchon 120 est pourvu d'un obturateur 121 relié au manchon 120 par une articulation 122 comportant un pion 123 reçu avec un ressort de rappel 125 dans une gouttière 124 comme pour le manchon 20 et l'obturateur 21 décrits ci-dessus.A sleeve 120 surrounds the socket. The sleeve 120 is provided with a shutter 121 connected to the sleeve 120 by a hinge 122 comprising a pin 123 received with a return spring 125 in a channel 124 as for the sleeve 20 and the shutter 21 described above.

Le raccordement des éléments de connecteur 100, 200 est analogue à celui des éléments de connecteur 1, 2.The connection of the connector elements 100, 200 is similar to that of the connector elements 1, 2.

L'invention n'est pas limitée aux modes de réalisation décrits, et on peut y apporter des variantes de réalisation sans sortir du cadre de l'invention tel que défini par les revendications.The invention is not limited to the embodiments described, and it is possible to provide alternative embodiments without departing from the scope of the invention as defined by the claims.

En particulier, les manchons 10, 20 peuvent être en une seule pièce avec les éléments de connecteur 1, 2 ou bien être rapportés sur ceux-ci et fixés, soit de façon amovible par clipsage ou collage, ou de façon inamovible par soudage ou surmoulage.In particular, the sleeves 10, 20 may be in one piece with the connector elements 1, 2 or be attached thereto and fixed, either removably by clipping or gluing, or irremovably by welding or overmoulding .

Bien que le ressort de rappel de l'obturateur 11 assure à la fois le rappel en pivotement et le rappel en translation, il est possible d'utiliser deux ressorts dédiés chacun à l'une des fonctions de rappel.Although the return spring of the shutter 11 provides both the return pivoting and the return in translation, it is possible to use two springs each dedicated to one of the return functions.

Les ressorts sont facultatifs et l'on peut prévoir des moyens de retenue des obturateurs dans leurs positions respectives par exemple par clipsage. D'autres types de ressorts sont utilisables et par exemple des ressorts en épingle pour le rappel en rotation (le ressort en épingle pouvant être partiellement noyé dans l'obturateur) ou un élastomère déformable pour le rappel en translation. En outre, les ressorts hélicoïdaux peuvent être montés autour du pivot plutôt qu'à l'extrémité libre de celui-ci.The springs are optional and one can provide means for retaining the shutters in their respective positions for example by clipping. Other types of springs are usable and for example springs hairpin for the return in rotation (the hairpin spring being partially embedded in the shutter) or a deformable elastomer for the return in translation. In addition, the coil springs may be mounted around the pivot rather than at the free end thereof.

Pour favoriser le glissement relatif des douilles et/ou manchons, il peut être prévu de recouvrir les surfaces en contact par du polytétrafluoréthylène (PTFE) ou similaire. Il est possible d'utiliser à cette fin un ruban en PTFE pouvant en outre jouer un rôle de rigidification de l'élément sur lequel il est fixé.To promote the relative sliding of the sleeves and / or sleeves, it can be expected to cover the contact surfaces with polytetrafluoroethylene (PTFE) or similar. It is possible to use for this purpose a PTFE tape that can also play a role of stiffening the element on which it is attached.

Les reliefs 17 peuvent avoir une forme différente de celle décrite et par exemple une forme symétrique, il est également possible d'avoir plusieurs reliefs disposés non symétriquement. A titre d'exemples de formes possibles :

  • trois ergots périphériques,
  • un ergot en bout du pivot et un ergot sur une portion opposée de l'obturateur.
The reliefs 17 may have a shape different from that described and for example a symmetrical shape, it is also possible to have several reliefs arranged non-symmetrically. As examples of possible forms:
  • three peripheral lugs,
  • a lug at the end of the pivot and a lug on an opposite portion of the shutter.

Les cavités correspondantes aux ergots, quelles que soient la forme et la disposition de ceux-ci, ont de préférence une forme facilitant l'évacuation des saletés, comme une forme évasée, lors de l'introduction des ergots. The cavities corresponding to the lugs, whatever the shape and the arrangement of the latter, preferably have a shape facilitating the evacuation of dirt, such as a flared shape, during the introduction of the lugs.
