Description

Prise de courant plus particulièrement destinée aux courants de forte intensité.Power outlet more particularly intended for high intensity currents.

L'invention concerne une prise de courant plus particulièrement destinée aux courants de forte intensité.The invention relates to a socket outlet more particularly intended for high intensity currents.

Les prises de courant comportent de manière connue un socle et une fiche munis chacun de contacts de puissance aménagés pour être électriquement connectés ou déconnectés entre eux.The sockets comprise in known manner a base and a plug each provided with power contacts arranged to be electrically connected or disconnected between them.

Dans les prises de forte intensité, il est généralement prévu un circuit parallèle de faible intensité, dénommé ci-après circuit pilote, qui est muni de contacts pilotes aménagés dans le socle et la fiche, et qui est destiné à commander, par sa fermeture ou respectivement son ouverture, un appareil de mise sous tension, ou respectivement hors tension, des contacts de puissance du socle.In high intensity sockets, a low intensity parallel circuit is generally provided, hereinafter called the pilot circuit, which is provided with pilot contacts arranged in the base and the plug, and which is intended to control, by closing or respectively its opening, a device for energizing, or respectively de-energizing, the power contacts of the base.

De la sorte, on cherche à réaliser d'une part, la fermeture du circuit pilote qu'après la connexion des contacts de puissance et au contraire d'autre part, son ouverture avant la déconnexion des contacts de puissance de telle sorte que ces deux opérations de connexion et de déconnexion se fassent hors tension.In this way, it is sought to achieve on the one hand, the closing of the pilot circuit only after the connection of the power contacts and on the contrary on the other hand, its opening before the disconnection of the power contacts so that these two connection and disconnection operations are carried out with the power off.

Il est en effet souvent impératif de rapprocher ou séparer les contacts de puissance, hors tension, de manière notamment à éviter les arcs électriques, pour n'établir la mise sous tension que lorsque lesdits contacts sont en position de connexion électrique.It is indeed often imperative to bring together or separate the power contacts, de-energized, so as in particular to avoid electric arcs, in order to establish energization only when said contacts are in the electrical connection position.

La connexion et la déconnexion des contacts de puissance de la fiche et du socle s'effectuent généralement par les manoeuvres d'enfichage et respectivement de séparation de la fiche et du socle.The connection and disconnection of the power contacts of the plug and the base are generally carried out by the plugging and separation operations respectively of the plug and the base.

L'invention concerne une prise de ce type munie d'un circuit pilote et qui est remarquable en ce que les contacts pilotes du socle et de la fiche sont connectés ou déconnectés entre eux, pour fermer ou ouvrir le circuit pilote, au moyen d'un dispositif de manoeuvre qui agit sur les contacts pilotes du socle ou de la fiche et qui est aménagé sur le socle ou respectivement la fiche, de manière telle que ledit dispositif, empêche au moins certaines manoeuvres d'enfichage et de séparation de la fiche et du socle, lorsqu'il est en position de fermeture du circuit pilote, pour interdire, dans cette position, la connexion et respectivement la déconnexion des contacts de puissance et, au contraire, autorise lesdites manoeuvres lorsqu'il est en position d'ouverture du circuit pilote.The invention relates to a socket of this type provided with a pilot circuit and which is remarkable in that the pilot contacts of the base and of the plug are connected or disconnected together, to close or open the pilot circuit, by means of an operating device which acts on the pilot contacts of the base or of the plug and which is arranged on the base or respectively of the plug, in such a way that said device prevents at least certain insertion and separation operations of the plug and the base, when it is in the closed position of the pilot circuit, to prohibit, in this position, the connection and disconnection of the power contacts respectively and, on the contrary, authorizes said maneuvers when in the open position of the pilot circuit.

Un tel dispositif offre une grande sécurité puisqu'il interdit d'une part, une connexion et, d'autre part, une déconnexion des contacts de puissance de la fiche et du socle lorsque les contacts de puissance de ce dernier sont sous tension.Such a device offers great security since it prohibits on the one hand, a connection and, on the other hand, a disconnection of the power contacts of the plug and of the base when the power contacts of the latter are energized.

Avantageusement, et cela améliore encore la sécurité, la fiche et/ou respectivement le socle sont munis de moyens qui empêchent l'actionnement du dispositif de manoeuvre vers sa position de fermeture du circuit pilote tant que l'enfichage de la fiche n'est pas suffisant pour entraîner la connexion des contacts de puissance.Advantageously, and this further improves safety, the plug and / or respectively the base are provided with means which prevent actuation of the operating device towards its closed position of the pilot circuit as long as the plug is not plugged in. sufficient to cause the connection of the power contacts.

Selon un mode de réalisation préféré, les têtes de contact des contacts pilotes du socle ou de la fiche sont mobiles et celles de la fiche ou respectivement du socle sont fixes, tandis que le dispositif de manoeuvre agit sur lesdites têtes de contact mobiles pour les amener vers ou à l'opposé des têtes de contact fixes afin d'opérer la connexion ou la déconnexion des contacts pilotes.According to a preferred embodiment, the contact heads of the pilot contacts of the base or of the plug are mobile and those of the plug or of the base respectively are fixed, while the operating device acts on said mobile contact heads to bring them towards or opposite the fixed contact heads in order to operate the connection or disconnection of the pilot contacts.

De préférence dans ce cas, les contacts pilotes sont des contacts en bout, les têtes de contact mobiles du socle ou de la fiche étant disposées à l'aide de ressorts et de conducteurs souples ou des tresses dans un bloc qui est monté mobile axialement et qui est entraîné par le dispositif de manoeuvre.Preferably in this case, the pilot contacts are end contacts, the movable contact heads of the base or of the plug being arranged using springs and flexible conductors or braids in a block which is mounted axially movable and which is driven by the operating device.

Avantageusement, le dispositif de manoeuvre est un dispositif rotatif muni d'un ergot d'entraînement qui coopère avec un logement du bloc des têtes de contact de manière à entraîner ce dernier en translation lorsque ledit ergot décrit un arc de cercle.Advantageously, the operating device is a rotary device provided with a drive lug which cooperates with a housing in the block of the contact heads so as to drive the latter in translation when said lug describes an arc of a circle.

L'invention concerne plus particulièrement, mais non exclusivement, une prise de courant dont l'enfichage consiste à introduire d'abord la fiche dans le socle et ensuite à tourner celle-ci dans le socle, pour obtenir la connexion des contacts de puissance.The invention relates more particularly, but not exclusively, to a socket outlet the insertion of which consists in first inserting the plug into the base and then in turning this in the base, to obtain the connection of the power contacts.

Un mode de réalisation de ce type selon l'invention est remarquable en ce que le dispositif de manoeuvre des contacts pilotes présente une partie d'actionnement tournant en forme de came aménagé à l'extérieur du socle ou de la fiche sur lequel il est monté et que la fiche ou respectivement le socle présente au moins une butée dont la forme coopère avec la forme de la came de manière telle, qu'en position relative d'introduction de la fiche dans le socle, la came, lorsqu'elle est en position de fermeture du circuit pilote, heurte au moins une partie de ladite butée et empêche ladite introduction alors qu'elle ne gêne pas cette introduction lorsqu'elle est en position d'ouverture, tandis que la manoeuvre de fermeture du circuit pilote par rotation de la came est possible après la rotation de la fiche et donc- la connexion des contacts de puissance, ladite came bloquant alors dans cette position une rotation inverse de la fiche en coopérant avec une partie correspondante de ladite butée et grâce à des moyens d'accrochage aménagés sur la fiche et le socle.An embodiment of this type according to the invention is remarkable in that the device for operating the pilot contacts has an actuating part rotating in the form of a cam arranged outside the base or the plug on which it is mounted. and that the plug or respectively the base has at least one stop whose shape cooperates with the shape of the cam so that, in the relative position of insertion of the plug into the base, the cam, when it is in closed position of the pilot circuit, strikes at least part of said stop and prevents said introduction while it does not hinder this introduction when it is in the open position, while the closing operation of the pilot circuit by rotation of the cam is possible after the rotation of the plug and therefore- the connection of the power contacts, said cam then blocking in this position reverse rotation of the plug by cooperating with a corresponding part of said stopper e t thanks to hooking means arranged on the plug and the base.

Les moyens d'accrochage sont par exemple formés par des pions aménagés dans la fiche et des saillies aménagées sur le socle, les pions étant destinés à venir sous les saillies par rotation de la fiche dans le socle.The attachment means are for example formed by pins arranged in the plug and projections arranged on the base, the pins being intended to come under the projections by rotation of the plug in the base.

Avantageusement, les saillies du socle présentent alors un pan incliné dont l'orientation permet un rapprochement de la fiche dans le socle au cours de la rotation de ladite fiche dans le socle et l'écrasement d'un joint d'étanchéité disposé entre la fiche et le socle.Advantageously, the projections of the base then have an inclined face whose orientation allows the plug to be brought closer into the base during the rotation of said plug in the base and the crushing of a seal placed between the plug. and the base.

En outre, et de préférence, le socle présente au moins une butée destinée à empêcher une rotation de la fiche dans le mauvais sens après son introduction dans le socle et au moins une butée destinée à limiter en fin de course la rotation de la fiche dans le socle, lesdites butées coopèrant avec les pions de la fiche.In addition, and preferably, the base has at least one stop intended to prevent rotation of the plug in the wrong direction after its introduction into the base and at least one stop intended to limit the rotation of the plug at the end of its travel. the base, said stops cooperating with the pins of the plug.

D'autre particularités et avantages sont également prévus par l'invention.Other features and advantages are also provided by the invention.

C'est ainsi que le socle présente avantageusement un rebord muni de réserves destinées au passage des pions de la fiche, la position angulaire des réserves étant telle qu'elle impose une bonne introduction en positionéde la fiche dans le socle.This is how the base advantageously presents a rim provided with reserves intended for the passage of the pins of the plug, the angular position of the reserves being such that it imposes a good insertion in position e of the plug in the base.

De même, pour compléter encore la sécurité, le dispositif de manoeuvre des contacts pilotes est pourvu d'un moyen de blocage en position de fermeture et/ou d'ouverture du circuit pilote.Similarly, to further complete the safety, the device for operating the pilot contacts is provided with a locking means in the closed and / or open position of the pilot circuit.

The invention will be clearly understood on reading the description which follows of an embodiment according to the invention and which refers to the appended drawings in which:
  • FIG. 1 is an elevation of the base and part of the plug according to the invention,
  • FIG. 2 is a top view of the base,
  • FIGS. 3 and are partial or straight sections of a pair of power contacts in two different positions,
  • FIGS. 5 and 6 are axial sections of the plug and of the base with the power contacts connected, the pilot circuit being respectively open (fig 5) and closed (fig 6),
  • - Figures 7a to 7d schematically show several relative positions of a part of the body of the plug relative to the device for operating the pilot contacts with, opposite, the corresponding positions of a pilot contact.

Les figures 1 et 5,6 montrent une prise de courant comportant un socle 1 et une fiche 2, cette dernière étant formée d'un corps de fiche 3, d'un corps de poignée 4 et d'un couvercle de poignée 5 (figures 5 et 6).Figures 1 and 5.6 show an outlet with a base 1 and a plug 2, the latter being formed of a plug body 3, a handle body 4 and a handle cover 5 (Figures 5 and 6).

La poignée de fiche 4,5 est coudée pour faciliter les manoeuvres dont il sera question ci-après.The plug handle 4.5 is bent to facilitate the maneuvers which will be discussed below.

La fiche comporte des contacts de puissance et des contacts pilotes sous forme de broches respectivement 6 et 7a,7b (figures 5 et 6).The plug includes power contacts and pilot contacts in the form of pins respectively 6 and 7a, 7b (Figures 5 and 6).

Le socle est également muni de contacts de puissance 8 et de contacts pilotes 9a,9b.The base is also provided with power contacts 8 and pilot contacts 9a, 9b.

On entend par contacts de puissance, les contacts de phase, le neutre, et éventuellement une prise de terre, et par contacts pilotes, les contacts destinés à former un circuit pilote pour commander, comme il a déjà été dit, un dispositif de coupure du courant disposé en amont du socle.By power contacts is meant phase contacts, neutral, and possibly an earth connection, and by pilot contacts, the contacts intended to form a pilot circuit for controlling, as has already been said, a current cut-off device disposed upstream of the base.

En outre, il est clair que les contacts pilotes peuvent également servir de contacts auxiliaires pour commander d'autres dispositifs ou allumer, par exemple, des voyants de contrôle.In addition, it is clear that the pilot contacts can also serve as auxiliary contacts for controlling other devices or lighting, for example, indicator lights.

Dans l'exemple représenté, il est prévu pour le socle et pour la fiche cinq contacts de puissance (3 phases, un neutre et une terre) et quatre contacts pilotes (non visibles en totalité sur les dessins).In the example shown, there are provided for the base and for the plug five power contacts (3 phases, one neutral and one earth) and four pilot contacts (not fully visible in the drawings).

Comme beaucoup de prise de forte intensité, le socle est muni d'un disque de sécurité 10 (figure 2,5,6 et 7a à 7d), qui est muni d'ajours 11a à 11e et 12a à 12d (figure 2) pour le passage des contacts de puissance et respectivement pilotes de la fiche.Like many high-intensity sockets, the base is provided with a safety disk 10 (figure 2,5,6 and 7a to 7d), which is provided with openings 11a to 11e and 12a to 12d (figure 2) to the passage of the power and pilot contacts of the plug respectively.

Toutefois au repos, les ajours 11a à 11e et 12a à 12d ne sont pas à l'aplomb des contacts du socle pour éviter que l'on puisse toucher ces derniers par mégarde.However, at rest, the openings 11a to 11e and 12a to 12d are not vertically in line with the contacts of the base to prevent them from being touched inadvertently.

Les contacts de puissance 8 du socle sont formés par des têtes de contact sollicités vers l'extérieur par des ressorts 13 qui prennent appui sur une partie isolante du socle, tandis que lesdites têtes sont reliées électriquement de manière fixe au socle par des lamelles flexibles 14 en cuivre (figures 5 et 6).The power contacts 8 of the base are formed by contact heads biased towards the outside by springs 13 which bear on an insulating part of the base, while said heads are electrically fixedly connected to the base by flexible strips 14 made of copper (Figures 5 and 6).

Les contacts pilotes 9a,9b du socle sont formés de manière connue, comme le montrent les figures 5 et 6 par des têtes de contact sollicités vers l'extérieur par des ressorts 15a,15b tandis qu'elles sont reliées électriquement de manière fixe au socle par des tresses conductrices 16a,16b. Ces tresses peuvent être des tresses pleines qui ondulent plus ou moins ou des tresses creuses qui peuvent se comprimer ou encore d'autres conducteurs souples.The pilot contacts 9a, 9b of the base are formed in a known manner, as shown in FIGS. 5 and 6 by contact heads stressed outwards by springs 15a, 15b while they are electrically fixedly connected to the base. by conductive braids 16a, 16b. These braids can be full braids which more or less undulate or hollow braids which can compress or other flexible conductors.

Les têtes de contact des contacts pilotes 9a,9b du socle sont montés selon l'invention dans un bloc isolant 17 constitué de deux parties (pour des raisons de montage desdits contacts), les têtes de contact étant mobiles à l'intérieur dudit bloc, et sollicitées vers la partie supérieure du bloc par les ressorts 15a,15b qui sont calés entre lesdites têtes et une partie du bloc.The contact heads of the pilot contacts 9a, 9b of the base are mounted according to the invention in an insulating block 17 made up of two parts (for reasons of mounting said contacts), the contact heads being movable inside said block, and urged towards the upper part of the block by the springs 15a, 15b which are wedged between said heads and a part of the block.

Le bloc 17 est monté mobile axialement dans le socle et présente un logement dans lequel est introduit un téton 18 solidaire d'un dispositif de manoeuvre 19 (figures 5 et 6) monté rotatif de manière étanche dans le socle à l'aide d'un joint torique 20.The block 17 is mounted axially movable in the base and has a housing in which is introduced a stud 18 secured to an operating device 19 (Figures 5 and 6) rotatably mounted in a sealed manner in the base using a O-ring 20.

Le dispositif de manoeuvre 19 traverse le socle et présente une partie extérieure en forme de came 21 (figures 1,5,6 et 7a à 7d).The operating device 19 crosses the base and has an external part in the form of a cam 21 (FIGS. 1,5,6 and 7a to 7d).

Cette partie extérieure ou came 21 présente la forme d'un disque auquel a été retiré un segment (figures 1, 7a à 7d)This outer part or cam 21 has the shape of a disc from which a segment has been removed (FIGS. 1, 7a to 7d)

Comme le montre plus particulièrement la figure 1, la fiche 2 comporte des butées d'accrochage sous forme de pions 22a et 22b tandis que le socle présente un rebord 23 et des saillies 24a,24b ainsi qu'au moins une butée 25 dont il sera question ci- apres.As shown more particularly in FIG. 1, the sheet 2 comprises hooking stops in the form of pins 22a and 22b while the base has a rim 23 and projections 24a, 24b as well as at least one stop 25 which will be question below.

Le rebord 23 du socle est pourvu de réserves 26a à 26c pour le passage des pions 22a,22b de la fiche (plus un pion non visible sur la figure 1).The rim 23 of the base is provided with reserves 26a to 26c for the passage of the pins 22a, 22b of the plug (plus a pin not visible in Figure 1).

Les saillies 24a,24b. (plus une non visible sur la figure 1) du socle présentent un pan incliné et un retour d'équerre 27 (figure 1).The projections 24a, 24b. (plus one not visible in Figure 1) of the base have an inclined face and a return square 27 (Figure 1).

La fiche est en outre munie d'une butée, ici sous l'aspect d'un logement 28 (figures 1 et 5,6) de forme et de dimensions qui correspondent à la forme de la came 21, en présentant une partie plate 28a et une partie bombée 28b.The plug is further provided with a stop, here in the form of a housing 28 (FIGS. 1 and 5,6) of shape and dimensions which correspond to the shape of the cam 21, by presenting a flat part 28a and a convex part 28b.

Le fonctionnement de la prise selon l'invention est le suivant, en se référant aux figures déjà décrites ainsi qu'aux figures 3 et 4, les schémas 7a à 7d ne montrant pour simplifier qu'un seul contact pilote 7a de la fiche et qu'une tête d'un contact pilote du socle, référencée 9a.The operation of the socket according to the invention is as follows, with reference to the figures already described as well as to Figures 3 and 4, the diagrams 7a to 7d showing for simplicity only one pilot contact 7a of the plug and that 'A head of a pilot contact of the base, referenced 9a.

La fiche 2 est amenée par sa poignée au dessus du socle 1 (figure 1 et 7a), la came 21 étant dans la position montrée à la figure 1.The plug 2 is brought by its handle above the base 1 (FIGS. 1 and 7a), the cam 21 being in the position shown in FIG. 1.

On introduit ensuite les contacts 7a,7b et 8 de la fiche dans les ajours 11a à 11e et 12a à 12c du disque de sécurité 10 du socle.The contacts 7a, 7b and 8 of the plug are then introduced into the openings 11a to 11e and 12a to 12c of the safety disc 10 of the base.

Les pions 22a,22b de la fiche passent au cours de cette introduction dans les réserves correspondantes 26a,26b du socle.The pins 22a, 22b of the plug pass during this introduction into the corresponding reserves 26a, 26b of the base.

Il est clair que la disposition angulaire des pions et des réserves positionne convenablement la fiche par rapport au socle.It is clear that the angular arrangement of the pins and the reserves appropriately positions the plug relative to the base.

Une fois introduite, la fiche se présente dans la position montrée aux figures 3 et 7b, c'est-à-dire que les contacts de puissance 6 et 8 et les contacts pilotes 7a,7b et 9a,9b ne sont pas connectés, les têtes des contacts de puissance 6 et 8 étant toutefois sensiblement dans un même plan mais décalées angulairement.Once inserted, the plug is in the position shown in Figures 3 and 7b, that is to say that the power contacts 6 and 8 and the pilot contacts 7a, 7b and 9a, 9b are not connected, the power contact heads 6 and 8, however, being substantially in the same plane but angularly offset.

Comme le montre plus particulièrement la figure 7b, cette introduction ne peut s'effectuer que pour la position de la came 21 représentée notamment aux figures 1 et 7b.As shown more particularly in FIG. 7b, this introduction can only be carried out for the position of the cam 21 shown in particular in FIGS. 1 and 7b.

En effet si la came 21 était dans la position montrée à la figure 7d, sa partie supérieure circulaire heurterait la partie plate 28a du logement 28 de la fiche, empêchant d'introduire davantage ladite fiche.Indeed if the cam 21 was in the position shown in Figure 7d, its circular upper part would strike the flat part 28a of the housing 28 of the plug, preventing further introduction of said plug.

La position de la came 21 pour l'introduction est également celle vue sur la figure 5 qui montre que dans cette position le bloc mobile 17 est dans sa position la plus basse.The position of the cam 21 for the introduction is also that seen in FIG. 5 which shows that in this position the movable block 17 is in its lowest position.

Après l'introduction de la fiche, on effectue une rotation de celle-ci dans le socle.After the insertion of the plug, it is rotated in the base.

La rotation de la fiche ne peut s'effectuer que dans un sens à cause de la butée 25 coopérant avec le pion 22b, et d'une valeur angulaire limitée par les retours d'équerre 27 des saillies 24a,24b du socle qui servent de butée de fin course aux pions 22a,22b, ces derniers venant s'accrocher sous lesdites saillies. Les pans inclinés des saillies 24a,24b sont orientés vers le bas par rapport au sens de rotation de la fiche de telle sorte que la fiche vient se serrer davantage sur le socle en écrasant un joint d'étanchéité 29 (figures 5 et 6) prévu entre la fiche et le socle.The rotation of the plug can only be carried out in one direction because of the stop 25 cooperating with the pin 22b, and of an angular value limited by the square returns 27 of the projections 24a, 24b of the base which serve as end of travel stop to the pins 22a, 22b, the latter coming to hang under said projections. The inclined faces of the projections 24a, 24b are oriented downwards with respect to the direction of rotation of the plug so that the plug is tightened more on the base by crushing a seal 29 (Figures 5 and 6) provided between the plug and the base.

Au cours de la rotation les contacts de la fiche entraînent le disque de sécurité 10.During rotation, the plug contacts drive the safety disk 10.

Les contacts de puissance 6 de la fiche viennent en connexion électrique avec les contacts de puissance 8 du socle par rotation comme le montre la figure 4, les ressorts 13 assurant une pression de contact.The power contacts 6 of the plug come into electrical connection with the power contacts 8 of the base by rotation as shown in FIG. 4, the springs 13 ensuring a contact pressure.

Les contacts pilotes 7a,7b de la fiche viennent eux en regard dès contacts pilotes 9a,9b du socle, comme le montrent les figures 5 et 7c, mais sans se toucher (le bloc 17 étant en position basse comme déjà dit).The pilot contacts 7a, 7b of the plug face them as soon as pilot contacts 9a, 9b of the base, as shown in FIGS. 5 and 7c, but without touching (the block 17 being in the low position as already said).

Dans cette dernière position (figures 5 et 7c) il est clair que la connexion des contacts de puissance est réalisée mais pas celle des contacts pilotes.In this last position (Figures 5 and 7c) it is clear that the connection of the power contacts is made but not that of the pilot contacts.

En outre, il est clair aussi qu'il n'est pas possible pendant cette manoeuvre (passage de la figure 7b à 7c) d'actionner la came 21, à cause de la partie plate 28a du logement 28.In addition, it is also clear that it is not possible during this maneuver (passage from FIG. 7b to 7c) to actuate the cam 21, because of the flat part 28a of the housing 28.

La dernière opération consiste à connecter les contacts pilotes et pour se faire, il suffit de faire tourner la came 21 de 180* à l'aide d'une clef introduite dans une empreinte hexagonale 30 prévue en son centre. Le logement 28 est pourvu d'une - échancrure 31 (figure 1) pour le passage de la clef.The last operation consists in connecting the pilot contacts and to do this, it suffices to rotate the cam 21 by 180 * using a key inserted into a hexagonal imprint 30 provided in its center. The housing 28 is provided with a - notch 31 (Figure 1) for the passage of the key.

Après rotation de la came 21 comme il vient d'être dit, celle-ci prend la position montrée aux figures 6 et 7d, c'est-à-dire qu'une partie circulaire de ladite came vient se placer dans la partie bombée 28b du logement 28.After rotation of the cam 21 as it has just been said, it takes the position shown in Figures 6 and 7d, that is to say that a circular part of said cam is placed in the convex part 28b housing 28.

Au cours de la rotation de la came 21, le téton 18 du dispositif 19 (figures 5 et 6) décrit un demi-cercle et entraîne en translation axiale le bloc isolant 17 de telle sorte que les têtes des contacts pilotes 9a et 9b du socle viennent toucher les contacts pilotes 7a,7b de la fiche (figure 6 et figure 7d sur laquelle la position antérieure de la tête du contact 9a est indiquée en pointillés en 9'a).During the rotation of the cam 21, the stud 18 of the device 19 (FIGS. 5 and 6) describes a semicircle and drives the insulating block 17 in axial translation so that the heads of the pilot contacts 9a and 9b of the base touch the pilot contacts 7a, 7b of the plug (FIG. 6 and FIG. 7d on which the anterior position of the head of the contact 9a is indicated by dotted lines at 9'a).

Les contacts pilotes 9a,9b sont aussi en contact électrique sous pression avec les contacts pilotes 7a,7b grâce aux ressorts 15a et 15b.The pilot contacts 9a, 9b are also in electrical contact under pressure with the pilot contacts 7a, 7b thanks to the springs 15a and 15b.

Pendant ce mouvement de translation du bloc 17, les têtes de contact des contacts 9a,9b suivent ce dernier grâce aux tresses conductrices 16a, 16b qui s'allongent en perdant au moins une partie de leur ondulation initiale ou en se détendant pour passer de la position de la figure 5 à celle de la figure 6, position dans laquelle les ressorts 15a et 15b se compriment légèrement sous l'action des contacts 7a,7b. Un mouvement inverse du bloc 17 par rotation inverse de la came 21 entraîne bien évidemment une détente des ressorts 15a,15b puis une ondulation ou une compression des tresses 16a,16b.During this translational movement of the block 17, the contact heads of the contacts 9a, 9b follow the latter thanks to the conductive braids 16a, 16b which lengthen while losing at least part of their initial undulation or by relaxing to pass from the position of Figure 5 to that of Figure 6, position in which the springs 15a and 15b compress slightly under the action of contacts 7a, 7b. A reverse movement of the block 17 by reverse rotation of the cam 21 obviously leads to a relaxation of the springs 15a, 15b then an undulation or compression of the braids 16a, 16b.

La came 21 peut en outre être verrouillée dans la position des figures 6 et 7d au moyen par exemple d'une vis imperdable actionnée par une clef introduite dans une empreinte 32 prévue à cet effet, la clef passant par une échancrure 33 du logement 28 (figure 1). Ce verrouillage peut également être prévu pour la position d'ouverture du circuit pilote des figures 1,5 et 7a à 7c.The cam 21 can also be locked in the position in FIGS. 6 and 7d by means, for example, of a captive screw actuated by a key inserted into an imprint 32 provided for this purpose, the key passing through a notch 33 in the housing 28 ( figure 1). This locking can also be provided for the open position of the pilot circuit of Figures 1.5 and 7a to 7c.

La connexion des contacts pilotes entraîne la mise sous tension des contacts de puissance 8 du socle, ceux-ci étant déjà connectés aux contacts de puissance 6 de la fiche.The connection of the pilot contacts causes the power contacts 8 of the base to be energized, these being already connected to the power contacts 6 of the plug.

Il est clair que dans cette position finale de connexion (figure 6 et 7d), il est impossible de tourner la fiche en sens inverse puisque celle-ci est retenue en rotation par la came 21 et la partie bombée 28b du logement 28 ainsi qu'en translation par les pions 22a,22b et les saillies 24a,24b.It is clear that in this final connection position (FIGS. 6 and 7d), it is impossible to turn the plug in the opposite direction since it is held in rotation by the cam 21 and the convex part 28b of the housing 28 as well as in translation by the pins 22a, 22b and the projections 24a, 24b.

Pour séparer la fiche du socle, il est donc nécessaire d'abord de déverrouiller la came 21 et de la manoeuvrer de nouveau de 180* pour l'amener de la position des figures 6 et 7d à la position des figures 5 et 7c de telle sorte que les contacts pilotes se séparent par translation axiale inverse du bloc 17, mettant ainsi les contacts de puissance 8 hors tension.To separate the plug from the base, it is therefore necessary first of all to unlock the cam 21 and to maneuver it again 180 * to bring it from the position of FIGS. 6 and 7d to the position of FIGS. 5 and 7c of such so that the pilot contacts separate by reverse axial translation of the block 17, thus putting the power contacts 8 off.

La séparation complète de la fiche et du socle s'effectue alors par des manoeuvres inverses de celles de l'enfichage (rotation inverse, translation de séparation), et la prise se retrouve dans la position des figures 1 et 7a.The complete separation of the plug and the base is then carried out by reverse maneuvers from those of the plugging (reverse rotation, separation translation), and the socket is found in the position of FIGS. 1 and 7a.

Le mode de réalisation décrit peut subir de nombreuses modifications, notamment en ce qui concerne le nombre et les formes des contacts de puissance et pilotes, ainsi que sur le nombre et les formes des butées et saillies.The described embodiment can undergo many modifications, in particular as regards the number and the forms of the power and pilot contacts, as well as on the number and the forms of the stops and projections.

En outre, si le dispositif 19 et le bloc 17 sont aménagés dans le socle, il est envisageable de prévoir un mode de réalisation où ceux-ci sont prévus dans la fiche.In addition, if the device 19 and the block 17 are arranged in the base, it is conceivable to provide an embodiment where these are provided in the sheet.
