Abstract

The base of an electro-pneumatic distributor consists of a body (1) with a face (3) containing a hole (5) into which is pushed the connector (2). This base contains in a plane parallel to this surface (3), a locking pin (10) to hold in position the connector (2), which is deformable from a state of rest when the arms (10a,10b) are at a secant to the hole (5) to a state of separation of the arms (10'a,10'b) when they are at a tangent to the hole (5), on the insertion of the connector. This pin is placed in a housing (8) also parallel to the surface (3).

Description

La présente invention concerne un composant pneumatique tel par exemple qu'une embase de distributeur électropneumatique, qui possède des moyens pour recevoir des raccords pneumatiques. The present invention relates to a pneumatic component such as for example an electropneumatic distributor base, which has means for receiving pneumatic fittings.

Un tel composant comporte généralement un corps qui est délimité par une surface de façade dans laquelle sont implantés les raccords. A cet effet, le corps comporte un alésage qui s'ouvre sur cette surface dans lequel on loge l'extrémité d'un raccord qui est généralement constitué par un embout cylindrique pourvu sur sa surface extérieure d'un joint et d'une gorge. Dans les dispositifs connus, le maintien du raccord dans l'alésage s'effectue par la mise en place, une fois le raccord introduit dans l'alésage, d'un cavalier ou d'une barrette transversalement à l'axe de l'alésage et à partir de l'extérieur du corps, de sorte qu'une portion de ce cavalier ou de cette barrette vienne se loger dans la gorge du raccord. Ce cavalier ou cette barrette est rendue ensuite prisonnière à l'intérieur du corps du composant en général par la mise en place d'un autre composant pneumatique empilé sur ou juxtaposé au composant recevant le ou les raccords qui forme ainsi obturateur de l'orifice d'introduction et de mise en place du cavalier ou de la barrette de verrouillage. Such a component generally comprises a body which is delimited by a facade surface in which the fittings are implanted. To this end, the body has a bore which opens on this surface in which the end of a fitting is housed, which generally consists of a cylindrical end-piece provided on its outer surface with a seal and a groove. In known devices, the fitting is maintained in the bore by placing, once the fitting inserted in the bore, a jumper or a bar transverse to the axis of the bore and from the outside of the body, so that a portion of this jumper or this bar comes to be housed in the groove of the fitting. This jumper or this bar is then made captive inside the body of the component in general by the installation of another pneumatic component stacked on or juxtaposed with the component receiving the fitting or fittings which thus forms a shutter of the orifice d 'introduction and placement of the jumper or the locking bar.

Dans le cas d'installations modulaires dans lesquelles on assemble divers composants, il faut préalablement à l'assemblage, équiper le composant destiné à recevoir les raccords d'une part de ses raccords et d'autre part de ses cavaliers ou barrettes de verrouillage. Un oubli à ce stade du montage est mal commode car il demande le démontage de tout ou partie de l'assemblage afin de mettre en place raccords et organes de verrouillage. In the case of modular installations in which various components are assembled, prior to assembly, it is necessary to equip the component intended to receive the fittings on the one hand with its fittings and on the other hand with its jumpers or locking bars. An oversight at this stage of the assembly is inconvenient because it requires the disassembly of all or part of the assembly in order to set up fittings and locking members.

La présente invention entend remédier à cet inconvénient au moyen d'un organe de verrouillage qu' il est possible de mettre en place dans le composant avant même que ce composant soit équipé des raccords destinés à le relier avec, en général, les actionneurs à commander par l'installation. The present invention intends to remedy this drawback by means of a locking member which it is possible to put in place in the component even before this component is equipped with the fittings intended to connect it with, in general, the actuators to be controlled. by installation.

A cet effet la présente invention a pour objet un composant pneumatique destiné à recevoir au moins un raccord, comportant un corps limité par une surface d'implantation de ce raccord dans laquelle débouche un alésage d'accueil d'une extrémité de ce raccord. Selon l'invention, ce composant comporte, dans un plan parallèle à cette surface, une épingle de verrouillage du raccord, élastiquement déformable entre un état de repos où au moins une branche de cette épingle est sécante de l'alésage et un état escamoté dans lequel la branche est tangente à l'alésage, cette épingle étant située, avec jeu dans ce plan, dans un logement du corps également parallèle à ladite surface. To this end, the subject of the present invention is a pneumatic component intended to receive at least one connector, comprising a body bounded by an implantation surface of this connector into which opens a receiving bore at one end of this connector. According to the invention, this component comprises, in a plane parallel to this surface, a pin for locking the connector, elastically deformable between a state of rest where at least one branch of this pin intersects the bore and a state retracted in which the branch is tangent to the bore, this pin being located, with clearance in this plane, in a housing of the body also parallel to said surface.

Ainsi, chaque composant assemblé peut être préalablement équipé d'épingles de verrouillage puis être assemblé pour former l'installation désirée, les raccords pouvant être alors aisément enchâssés dans le corps, leur introduction provoquant l'effacement de la ou des branches de l'épingle destinées à son verrouillage, effacement élastique qui, lorsque l'introduction est achevée, permet à la ou aux branches de cette épingle de retomber dans la gorge du raccord. Bien entendu le démontage du raccord demande le désassemblage préalable de l'installation pneumatique qui intègre le composant (par exemple une embase dans une installation de distribution modulaire) afin de pouvoir accéder à l'épingle et la retirer, mais cette opération est très rarement réalisée. Thus, each assembled component can be previously equipped with locking pins and then be assembled to form the desired installation, the fittings can then be easily embedded in the body, their introduction causing the erasure of the branch or branches of the pin intended for its locking, elastic erasure which, when the introduction is complete, allows the branch or branches of this pin to fall back into the groove of the connector. Of course disassembly of the fitting requires prior disassembly of the pneumatic installation which integrates the component (for example a base in a modular distribution installation) in order to be able to access and remove the pin, but this operation is very rarely carried out .

Dans le cas où le composant comporte au moins deux alésages parallèles, le logement est réalisé entre ces deux alésages, une branche de l'épingle étant, au repos, sécante de l'alésage correspondant. In the case where the component comprises at least two parallel bores, the housing is produced between these two bores, a branch of the pin being, at rest, secant from the corresponding bore.

Lorsque le corps comporte un seul alésage, le logement est situé de manière que l'épingle chevauche l'alésage avec, au repos, ses deux branches sécantes de celui-ci. When the body has a single bore, the housing is located so that the pin overlaps the bore with, at rest, its two intersecting branches thereof.

De manière avantageuse, les branches de l'épingle sont conformées de manière à offrir une surface de glissement de l'extrémité du raccord introduite dans l'alésage qui favorise leur effacement au passage de cette extrémité. Advantageously, the branches of the pin are shaped so as to provide a sliding surface of the end of the fitting introduced into the bore which promotes their erasure when this end passes.

Enfin, le corps du composant est limité par une seconde surface perpendiculaire à la première au niveau de laquelle débouche le logement susdit de l'épingle permettant un accès à cette dernière. Finally, the body of the component is limited by a second surface perpendicular to the first at which the abovementioned housing of the pin opens out, allowing access to the latter.

D'autres particularités et avantages de l'invention ressortiront de la description donnée ci-après de deux variantes de réalisation. Other features and advantages of the invention will emerge from the description given below of two alternative embodiments.

Il sera fait référence aux dessins annexés, parmi lesquels
- les figures 1 et 2 illustrent par deux coupes orthogonales partielles une première réalisation d'un composant conforme à l'invention,
- les figures 3 et 4 illustrent également par deux coupes orthogonales une seconde réalisation d'un composant conforme à l'invention.Reference will be made to the accompanying drawings, among which
FIGS. 1 and 2 illustrate by two partial orthogonal sections a first embodiment of a component according to the invention,
- Figures 3 and 4 also illustrate by two orthogonal sections a second embodiment of a component according to the invention.

Aux figures 1 à 4, on a désigné par la référence 1 le corps du composant destiné à recevoir les raccords 2. In FIGS. 1 to 4, the body of the component intended to receive the fittings 2 has been designated by the reference 1.

Ce corps 1 est limité par une surface d'implantation 3 de ces raccords et par une surface 4 perpendiculaire à cette surface 3. Ils comportent également un ou deux alésages 5 d'axe perpendiculaire à la surface 3 qui servent à accommoder les raccords à installer.This body 1 is limited by an implantation surface 3 of these fittings and by a surface 4 perpendicular to this surface 3. They also have one or two bores 5 with an axis perpendicular to the surface 3 which serve to accommodate the fittings to be installed .

Chacun des raccords 2 comporte de manière connue un joint d'étanchéité 6 et une gorge extérieure 7 qui se trouve, lorsque le raccord est mis en place dans son alésage, au droit d'un logement 8 (figures 1 et 2) ou 9 (figures 3 et 4) du corps 1, ce logement étant constitué par une fente sensiblement parallèle à la surface 3 et débouchant à la surface 4 du corps 1. Dans le cas des figures 1 et 2, le logement 8 possède des parties qui entourent totalement la gorge 7 du raccord 2 tandis que dans le cas des figures 3 et 4, dans lequel le corps 1 comporte deux alésages 5 adjacents, le logement 9 est situé en regard des gorges 7 de chacun des raccords 2 entre ces deux alésages 5. Each of the fittings 2 comprises in known manner a seal 6 and an external groove 7 which is, when the fitting is placed in its bore, in line with a housing 8 (FIGS. 1 and 2) or 9 ( Figures 3 and 4) of the body 1, this housing being constituted by a slot substantially parallel to the surface 3 and opening at the surface 4 of the body 1. In the case of Figures 1 and 2, the housing 8 has parts which completely surround the groove 7 of the connector 2 while in the case of FIGS. 3 and 4, in which the body 1 has two adjacent bores 5, the housing 9 is located opposite the grooves 7 of each of the connectors 2 between these two bores 5.

Par la surface 4, on introduit dans le logement 8 un cavalier ou une épingle de verrouillage 10 dont les branches 10a et lOb sont écartées l'une de l'autre au repos de manière à venir en interférence avec l'alésage 5. La largeur du logement 8 est prise parallèlement à la surface 4 et est suffisante pour que les branches 10a et lOb puissent s'écarter élastiquement 10'a, 10'b au passage du connecteur 2 lors de son enchâssement. Via the surface 4, a jumper or a locking pin 10 is introduced into the housing 8, the arms 10a and 10b of which are spaced apart from one another at rest so as to interfere with the bore 5. The width of the housing 8 is taken parallel to the surface 4 and is sufficient for the branches 10a and 10b to be able to deviate elastically 10'a, 10'b in the passage of the connector 2 when it is embedded.

Aux figures 3 et 4, le logement 9 accommode une épingle 11 dont les branches lla et llb sont également en intersection, au repos, avec les alésages 6, ces branches étant élastiquement déformables ll'a et ll'b vers l'intérieur du logement 9 au passage de chaque raccord 2 lors de son enchâssement. Dans les deux cas de figure, les branches retombent élastiquement à l'intérieur des gorges 7 des raccords 2 mis en place. In FIGS. 3 and 4, the housing 9 accommodates a pin 11 whose branches lla and llb are also at intersection, at rest, with the bores 6, these branches being elastically deformable ll'a and ll'b towards the interior of the housing 9 when each connection 2 passes when it is embedded. In both cases, the branches fall elastically inside the grooves 7 of the fittings 2 in place.

L'épingle 10 est réalisée en un feuillard métallique plié et cambré qui est tel que ses branches 10a, lOb forment des volets à face inclinée pour faciliter leur écartement lors de l'introduction d'un raccord tel que 2. The pin 10 is made of a bent and bent metal strip which is such that its branches 10a, lOb form flaps with an inclined face to facilitate their separation during the introduction of a connector such as 2.

L'épingle 11 représentée est réalisée sous la forme d'un fil cambré dont les branches lla et llb peuvent être élastiquement repoussées l'une vers l'autre au passage des raccords 2. La surface cylindrique, extérieure de ce fil et coopérant avec un congé que possède naturellement le raccord 2 à son extrémité enchâssable, constitue des moyens qui facilitent l'effacement élastique de l'une des branches lors de l'introduction du raccord correspondant dans le corps. The pin 11 shown is produced in the form of a cambered wire whose branches 11a and 11b can be resiliently pushed towards one another when the fittings 2 pass. The cylindrical, external surface of this wire and cooperating with a leave that the fitting 2 naturally has at its plug-in end, constitutes means which facilitate the elastic erasure of one of the branches during the introduction of the corresponding fitting into the body.
