Description

Bague de repérage de la tension d'emploi d'un élément de connexion électrique.Ring marking the operating voltage of a connection element electric.

L'invention concerne un moyen de repérage pour indiquer la tension d'emploi d'un élément de connexion électrique, et elle concerne aussi un élément et un dispositif de connexion électrique équipé de tels moyens.The invention relates to a marking means for indicating the operating voltage of an electrical connection element, and it also relates to an element and a device electrical connection equipped with such means.

Les dispositifs de connexion électrique comportent généralement deux organes à accoupler entre eux.Electrical connection devices generally have two members to mate with each other.

Un tel dispositif peut consister, par exemple, en une prise de courant constituée d'un socle de prise de courant et d'une fiche, ou d'un prolongateur constitué d'une prise mobile et d'une fiche, ou encore d'un connecteur constitué d'un socle de connecteur et d'une prise mobile.Such a device can consist, for example, of a socket outlet constituted a socket outlet and a plug, or an extension consisting of a mobile socket and plug, or a connector consisting of a connector and mobile outlet.

Chaque organe à accoupler comporte un élément de connexion destiné à s'accoupler et se connecter électriquement avec l'élément de connexion de l'autre organe, et se présentant sous la forme d'un socle de prise de courant ou d'un socle de connecteur, lequel est monté sur un accessoire ou support tels une poignée, un boítier, un manchon, ou autre, un bâti de machine, etc.Each member to be coupled comprises a connection element intended to mate and connect electrically with the connecting element on the other organ, and being in the form of a socket outlet or a connector, which is mounted on an accessory or support such as a handle, a housing, a sleeve, or the like, a machine frame, etc.

Dans tous les cas, les caractéristiques électriques des deux éléments de connexion à accoupler doivent bien entendu correspondre pour assurer un passage correct du courant électrique de l'un à l'autre.In all cases, the electrical characteristics of the two elements of connection to be coupled must of course correspond to ensure passage correct electrical current from one to the other.

Par sécurité pour les personnes et les appareils, les éléments de connexion de ce type sont généralement pourvus de moyens de différenciation et de détrompage afin que seuls les éléments électriquement compatibles entre eux puissent s'accoupler.For security for people and devices, the connection elements of this type are generally provided with means of differentiation and polarization so that only electrically compatible elements can mate.

En outre, même s'il ne s'agit pas d'une question de sécurité, il peut s'avérer pratique que des éléments électriquement compatibles puissent se reconnaítre par un repérage particulier et notamment par une couleur choisie en fonction de la tension à délivrer ou à recevoir, les couleurs de repérage selon les tensions faisant d'ailleurs l'objet de recommandations dans certaines normes d'appareils électriques.In addition, even if it is not a security issue, it can be practical that electrically compatible elements can be recognized by a particular marking and in particular by a color chosen as a function of the voltage at to deliver or to receive, the colors of marking according to the tensions making besides subject to recommendations in certain electrical appliance standards.

Souvent, les moyens de détrompage nécessitent une fabrication particulière et il peut alors être envisagé de fabriquer les éléments de connexion ou une partie de ceux-ci d'une certaine couleur, qui sera fonction de manière conventionnelle des caractéristiques électriques dudit élément.Often the keying means require special manufacturing and it can then be envisaged to manufacture the connection elements or a part of these of a certain color, which will conventionally be a function of the characteristics of said element.

Toutefois, cette façon de procéder entraíne évidemment un surcoût.However, this procedure obviously involves an additional cost.

De plus, les moyens de différenciation des caractéristiques électriques comme dans les dispositifs généralement fabriqués par le demandeur, peuvent dépendre d'un simple positionnement angulaire du support des contacts électriques, toutes les pièces étant par ailleurs les mêmes pour diverses caractéristiques, de telle sorte que pour notamment des raisons évidentes de fabrication et de reconnaissance de gamme, toutes les pièces ont avantageusement la même couleur.In addition, the means of differentiating the electrical characteristics as in the devices generally manufactured by the applicant, may depend a simple angular positioning of the support of the electrical contacts, all parts being otherwise the same for various characteristics, such so that in particular for obvious reasons of manufacturing and recognition range, all the pieces advantageously have the same color.

Si l'on désire malgré tout créer un système de distinction ou de repérage par couleur, il y avait donc lieu de rechercher un moyen simple, efficace et permanent, qui n'obligeait pas à concevoir des dispositifs entiers ou en partie d'une certaine couleur. Ce problème était déjà posé depuis longtemps et n'avait pu être résolu jusqu'à présent.If you still want to create a system of distinction or identification by color, there was reason to look for a simple, effective and permanent way, which did not require the design of whole or part-colored devices. This problem had already been posed for a long time and had not been resolved until now.

Enfin, avec une couleur particulière attribuée seulement à une partie de l'élément de connexion, par exemple le couvercle de protection d'un socle de prise de courant, le repérage disparaít en cas de destruction dudit couvercle tandis que son remplacement, lorsque cela est possible, crée un risque de confusion entre les couleurs disponibles au cours de la réparation.Finally, with a particular color assigned only to a part of the element connection, for example the protective cover of a socket outlet, the identification disappears in the event of destruction of said cover while its replacement, where possible, creates a risk of color confusion available during repair.

L'invention propose à cet effet de manière originale, un moyen de repérage pour distinguer la tension d'emploi d'un élément de connexion électrique monté sur un accessoire ou support, désigné ci-après par support, qui est notamment remarquable en ce qu'il se présente sous la forme d'au moins une bague colorée qui est aménagée pour être intercalée entre l'élément de connexion et son support, au moins l'une des dimensions de la bague dans le sens diamétral étant au moins égale aux dimensions correspondantes de l'élément de connexion et/ou son support au niveau de leur plan d'assemblage afin de présenter une surface périphérique annulaire de visualisation qui, au moins en partie, affleure ou fait saillie dudit élément de connexion et/ou de son support.The invention proposes for this purpose in an original way, a means of location to distinguish the operating voltage of an electrical connection element mounted on a accessory or support, hereinafter referred to as support, which is notably remarkable in that it is in the form of at least one colored ring which is arranged to be inserted between the connection element and its support, at least one of the dimensions of the ring in the diametrical direction being at least equal to the dimensions of the connection element and / or its support at the level of their plane assembly to present an annular peripheral viewing surface which, at least in part, is flush with or protrudes from said connection element and / or its support.

La bague est, par exemple, serrée entre les deux pièces de l'élément de connexion et son support, par vissage.The ring is, for example, clamped between the two parts of the element connection and its support, by screwing.

Selon un mode de réalisation, la bague présente d'une part, une zone annulaire dans le plan d'assemblage de l'élément de connexion et de son support, laquelle est serrée entre ces derniers et, d'autre part, un rebord périphérique qui constitue la surface annulaire de visualisation, et sous lequel vient s'emboíter une partie de l'élément de connexion et/ou de son support. Dans ce cas, la paroi intérieure du rebord périphérique de la bague est avantageusement ajustée aux dimensions de la partie de l'élément de connexion ou de son support qui vient s'emboíter de telle sorte que la bague peut rester en place au cours du montage ou du démontage de l'élément de connexion sur son support. According to one embodiment, the ring has on the one hand, an annular zone in the assembly plane of the connection element and its support, which is clamped between these and, on the other hand, a peripheral rim which constitutes the annular viewing surface, and under which part of the element fits connection and / or its support. In this case, the inner wall of the rim ring device is advantageously adjusted to the dimensions of the part of the connection element or its support which fits so that the ring can remain in place during assembly or disassembly of the element connection on its support.

Entre l'élément de connexion et son support, il y a généralement un joint d'étanchéité et il peut être avantageux que la bague soit constituée au moins en partie d'une matière adéquate pour assurer en même temps la fonction de joint d'étanchéité.Between the connection element and its support, there is generally a seal sealing and it may be advantageous for the ring to be formed at least in part of an adequate material to ensure at the same time the function of seal.

De même, la bague peut en alternative ou de manière complémentaire, avoir encore une autre fonction. A cet effet, la bague fait, par exemple, saillie de l'élément de connexion et de son support et elle est constituée au moins en partie d'une matière adéquate pour assurer en même temps la fonction de protecteur de chocs.Similarly, the ring may alternatively or in addition, have yet another function. For this purpose, the ring projects, for example, from the element connection and its support and it consists at least in part of a material adequate to ensure at the same time the function of shock protector.

Il peut être aussi avantageux dans certains cas que la bague comporte au moins une protubérance en vue d'assurer la protection aux chocs d'une partie en saillie de l'élément de connexion, par exemple un ergot d'accrochage prévu sur l'un des éléments pour le crochet dont est muni l'autre élément à accoupler.It may also be advantageous in certain cases for the ring to include less a protuberance in order to ensure the impact protection of a part in projection of the connection element, for example a hooking lug provided on one elements for the hook with which the other element to be coupled is provided.

Il est clair que l'invention concerne aussi tout élément de connexion électrique monté sur un accessoire ou support et équipé d'au moins une telle bague et même, bien entendu, tout dispositif de connexion électrique comportant deux organes à accoupler entre eux, dont chacun est pourvu d'un élément de connexion électrique équipé d'au moins une bague selon l'invention car il est clair que l'intérêt de visualiser la tension d'emploi sur un élément est associé à la visualisation sur l'autre élément à accoupler.It is clear that the invention also relates to any element of electrical connection mounted on an accessory or support and equipped with at least one such ring and even, of course, any electrical connection device comprising two members to be coupled between them, each of which is provided with an electrical connection element fitted with at least one ring according to the invention because it is clear that the advantage of visualizing the operating voltage on one element is associated with the display on the other element to mate.

Les dispositifs de connexion peuvent être de nature diverse, comme déjà dit, et en particulier un socle de prise de courant et une fiche, ou une prise mobile et une fiche, ou encore un socle de connecteur et une prise mobile.The connection devices can be diverse in nature, as already said, and in particular a socket outlet and a plug, or a mobile socket and a plug, or a connector socket and a mobile socket.

L'invention sera bien comprise à la lecture de la description qui va suivre et qui se réfère aux dessins annexés dans lesquels:

  • la figure 1 représente une prise de courant constituée par un socle de prise de courant monté sur un boítier et par une fiche à poignée, la fiche étant représentée en position accouplée mais seules les bagues selon l'invention sont représentées en traits pleins sur cette figure,
  • les figures 2 et 3 sont des vues éclatées à axe brisé, respectivement de la fiche à poignée et du socle sur boítier de la figure 1.
The invention will be clearly understood on reading the description which follows and which refers to the appended drawings in which:
  • Figure 1 shows an outlet consisting of a socket outlet mounted on a housing and a plug with handle, the plug being shown in the coupled position but only the rings according to the invention are shown in solid lines in this figure ,
  • Figures 2 and 3 are exploded views with a broken axis, respectively of the handle plug and the base on the housing of Figure 1.

La prise de courant représentée à titre d'exemple sur les dessins, comporte donc une fiche 1 formée d'un socle de connecteur 2 et d'une poignée 3. The outlet shown as an example in the drawings, comprises therefore a plug 1 formed by a connector base 2 and a handle 3.

Le socle de connecteur 2 constitue l'élément de connexion de la fiche sur lequel est fixée ici la poignée 3, constituant un accessoire ou support et à laquelle sera arrimé un câble non représenté .The connector base 2 constitutes the connection element of the plug on which is fixed here the handle 3, constituting an accessory or support and to which will stowed a cable not shown.

Le socle de prise de courant 4 est ici monté sur un support sous la forme d'un boítier 5, ce dernier étant, par exemple, destiné à être fixé sur un mur en vue de constituer un socle mural.The socket outlet socket 4 is here mounted on a support in the form of a housing 5, the latter being, for example, intended to be fixed to a wall in order to constitute a wall base.

Le mot boítier doit d'ailleurs être compris dans son sens le plus général et il peut s'agir notamment d'un simple manchon, ou encore d'un coffret, voire d'une armoire de répartition ou autre.The word box must also be understood in its most general sense and it may include a simple sleeve, or a box, or even a cabinet distribution or whatever.

De manière connue, le socle de connecteur 2 de la fiche 1 est pourvu de contacts sous forme de broches et le socle de prise de courant 4 de contacts antagonistes disposés dans des logements isolants dont les ouvertures sont généralement protégées par un disque de sécurité rotatif destiné à être entraíné par les broches de la fiche.In known manner, the connector base 2 of the plug 1 is provided with contacts in the form of pins and the socket outlet 4 of antagonistic contacts arranged in insulating housings whose openings are generally protected by a rotating safety disc intended to be driven by the pins the sheet.

Le socle de prise de courant est par ailleurs pourvu d'un couvercle 6 et d'un crochet 7 destiné à venir s'accrocher sur un ergot 8 du socle de connecteur 2 afin de verrouiller la fiche et le socle de prise de courant en position accouplée de connexion.The socket outlet is also provided with a cover 6 and a hook 7 intended to be hooked on a lug 8 of the connector base 2 in order to lock the plug and socket-outlet in the coupled connection position.

Comme le montrent bien les figures 2 et 3, le socle de connecteur 2 et la poignée 3 sont fixés entre eux de même que le socle de prise de courant 4 et le boítier 5.As shown in Figures 2 and 3, the connector base 2 and the handle 3 are fixed together as well as the socket outlet 4 and the housing 5.

La fixation des pièces 2, 3 et respectivement 4, 5 s'effectue par exemple par vissage et on voit parfaitement les vis sur la figure 1 et les trous nécessaires dans les pièces sur les figures 2 et 3.The fixing of the parts 2, 3 and respectively 4, 5 is carried out for example by screwing and we can perfectly see the screws in Figure 1 and the necessary holes in the parts in Figures 2 and 3.

Entre le socle de connecteur 2 et la poignée 3 d'une part, et le socle de prise de courant 4 et le boítier 5 d'autre part, sont intercalées une bague 9a et respectivement 9b qui sont serrées entre les pièces vissées entre elles comme il vient d'être dit ci-avant.Between the connector base 2 and the handle 3 on the one hand, and the socket base current 4 and the housing 5 on the other hand, are interposed a ring 9a and respectively 9b which are clamped between the parts screwed together as has just been said above.

Comme le montrent ici les figures 2 et 3, les bagues 9a, 9b sont ici identiques grâce à des conceptions correspondantes des interfaces des pièces à assembler.As shown here in Figures 2 and 3, the rings 9a, 9b are identical here through corresponding designs of the interfaces of the parts to be assembled.

Les bagues 9a, 9b ont une couleur identique qui est différente de celle des pièces elles-mêmes, celles-ci étant généralement toutes de la même couleur.The rings 9a, 9b have an identical color which is different from that of the parts themselves, these generally being all of the same color.

Chaque bague 9a, 9b présente ici une zone annulaire 10a, 10b, destinée à être serrée entre les pièces à assembler et un rebord périphérique annulaire 11a, 11b, sous lequel vient s'emboïter une partie de l'une des pièces à assembler, comme le montre la figure 1, à savoir l'arrière du socle du connecteur 2 ou du socle de prise de courant 4 pour les bagues respectivement 9a et 9b. Le rebord périphérique 11a, 11b est avantageusement ajusté pour que la bague tienne en place sur la pièce correspondante, même si les deux pièces ne sont pas fixées l'une à l'autre, afin de faciliter les montages et démontages et éviter les risques de perte de ladite bague.Each ring 9a, 9b here has an annular zone 10a, 10b, intended for be clamped between the parts to be assembled and an annular peripheral rim 11a, 11b, under which comes part of one of the parts to be assembled, like the shows figure 1, namely the back of the connector socket 2 or the socket socket stream 4 for the rings 9a and 9b respectively. The peripheral edge 11a, 11b is advantageously adjusted so that the ring remains in place on the corresponding part, even if the two parts are not fixed to each other, in order to facilitate assemblies and disassembly and avoid the risk of loss of said ring.

Comme le montre bien la figure 1, le rebord 11a, 11b de la bague constitue une surface annulaire de visualisation.As shown in Figure 1, the flange 11a, 11b of the ring constitutes an annular viewing surface.

Le fait de prévoir une bague à emboítement permet de visualiser une surface annulaire convenable qui fait légèrement saillie des pièces sans nécessiter une épaisseur trop importante.The fact of providing a socket ring allows to visualize a surface suitable ring that protrudes slightly from the parts without requiring a thickness too important.

Toutefois, les bagues pourraient présenter des dimensions correspondantes à celles d'au moins l'une des pièces dans leur plan d'assemblage pour affleurer au moins celle-ci ou être légèrement supérieures pour en faire saillie, sans pour cela posséder un rebord.However, the rings could have corresponding dimensions to those of at least one of the parts in their assembly plan to be flush with the minus it or be slightly higher to project it, without having a ledge.

Généralement, les pièces à assembler sont pourvues d'un joint d'étanchéité disposé entre elles et il est clair que la matière utilisée pour les bagues 9a, 9b peut avantageusement être choisie pour réaliser aussi la fonction de joint d'étanchéité. Autrement dit, la nécessité ou l'utilité d'avoir un joint d'étanchéité et se servir de cette nécessité ou utilité pour concevoir une bague de distinction des tensions, ladite bague ayant alors au moins deux fonctions, est tout à fait original.Generally, the parts to be assembled are provided with a seal disposed between them and it is clear that the material used for the rings 9a, 9b can advantageously be chosen to also perform the function of seal. Other says, the need or the usefulness to have a gasket and make use of this necessity or utility to design a ring of distinction of tensions, said ring having at least two functions, is completely original.

En outre, une telle bague peut aussi servir de moyen protecteur de chocs, la matière constitutive étant alors choisie en conséquence.In addition, such a ring can also serve as a protective means of shock, the constituent material then being chosen accordingly.

Dans certains cas, on peut même prévoir des protubérances telles que 12a, 12'a et 12b, 12'b pour protéger des parties exposées ou en saillie de l'une des pièces, comme ici l'ergot 8 du socle de connecteur 2.In some cases, one can even provide protrusions such as 12a, 12'a and 12b, 12'b to protect exposed or protruding parts of one of the parts, as here the lug 8 of the connector base 2.

Si dans les modes de réalisation représentés, chaque élément ne présente qu'une bague, il est évident que plusieurs bagues peuvent être prévues, l'une indiquant par exemple une fourchette de tensions nominales d'emploi et l'autre une fourchette de fréquences. On peut aussi bien entendu prévoir une bague multicolore.If in the embodiments shown, each element does not have than a ring, it is obvious that several rings can be provided, one indicating for example a range of nominal operating voltages and the other a range frequencies. One can of course also provide a multicolored ring.

Comme déjà dit, l'invention s'étend non seulement à la bague mais à chaque élément de connexion ainsi équipé et à chaque dispositif constitué de deux éléments à accoupler.As already said, the invention extends not only to the ring but to each connection element thus equipped and to each device consisting of two elements to mate.

De plus, comme déjà dit aussi, si l'exemple représente une prise de courant formée d'une fiche et d'un socle de prise de courant, il pourrait s'agir d'un prolongateur (prise mobile et fiche) ou d'un connecteur (prisé mobile et socle de connecteur).In addition, as already said also, if the example represents an outlet formed of a plug and socket outlet, it could be an extension (mobile outlet and plug) or connector (mobile prized and connector base).

Enfin, on rappelle aussi que le socle de prise de courant ou le socle de connecteur pourrait être fixé sur un ensemble de plus grande dimension que la poignée ou le boítier représentés, comme par exemple une armoire de répartition, un bâti de machine ou similaire, ...Finally, it is also recalled that the socket outlet or the connector could be attached to a larger assembly than the handle or the box shown, such as a distribution cabinet, a frame machine or similar, ...
