Description

DOMAINE TECHNIQUE AUQUEL SE RAPPORTE L'INVENTIONTECHNICAL FIELD TO WHICH THE INVENTION REFERS

La présente invention concerne de manière générale le domaine des connecteurs électriques.The present invention generally relates to the field of electrical connectors.

Elle concerne plus particulièrement un ensemble de connexion électrique tel que défini dans le préambule de la revendication 1.It relates more particularly to an electrical connection assembly as defined in the preamble of claim 1.

ARRIERE-PLAN TECHNOLOGIQUEBACKGROUND

On connaît notamment du document US 3 521 216 un ensemble de connexion électrique tel que précité.We know in particular of the document US 3,521,216 an electrical connection assembly as aforesaid.

Dans ce document, les éléments de connexion de la prise de courant comportent, en saillie de la face de connexion de l'enveloppe de la prise, trois anneaux concentriques.In this document, the connection elements of the socket comprise, projecting from the connection face of the jack envelope, three concentric rings.

Les éléments de connexion de la fiche électrique comporte quant à eux, en saillie de la face de connexion de l'enveloppe de la fiche, un plot central et deux plots latéraux placés sur des cercles concentriques de mêmes diamètres que les anneaux concentriques de la prise de courant.The connecting elements of the electrical plug comprises, in turn, projecting from the connecting face of the plug casing, a central stud and two lateral studs placed on concentric circles of the same diameter as the concentric rings of the plug. current.

Grâce à ces éléments de connexion, lorsque la fiche électrique est enfichée dans la prise de courant, les plots de la fiche électrique se connectent aux anneaux de la prise de courant, de manière à fermer le circuit électrique entre la fiche électrique et la prise de courant.Thanks to these connection elements, when the plug is plugged into the socket, the plugs of the plug connect to the rings of the socket, so as to close the electrical circuit between the plug and the plug of the plug. current.

Dans ce document, les enveloppes de la fiche électrique et de la prise de courant logent chacune un aimant en forme d'anneau.In this document, the envelopes of the plug and socket each house a magnet shaped ring.

Ces aimants permettent ainsi de maintenir la fiche électrique enfichée dans la prise de courant tant qu'aucun effort de traction n'est exercé sur elle.These magnets thus make it possible to keep the electrical plug plugged into the socket as long as no traction force is exerted on it.

L'inconvénient majeur de cet ensemble de connexion est que la fiche électrique comme la prise de courant comportent un aimant susceptible d'interférer avec les circuits électroniques des appareils médicaux sensibles aux champs magnétiques (par exemple les stimulateurs cardiaques). Il ne peut donc pas être utilisé en milieu hospitalier.The major disadvantage of this connection assembly is that the electrical plug as the socket has a magnet that may interfere with the electronic circuits of medical devices sensitive to magnetic fields (eg pacemakers). It can not be used in hospitals.

On connaît par ailleurs du document EP 1 921 893 un ensemble comportant une oreillette équipée d'une batterie interne et un chargeur agencé pour recharger la batterie interne de cette oreillette. Dans ce document, le chargeur comporte un boîtier qui loge un aimant tandis que la batterie interne de l'oreillette forme un élément magnétisable. Le chargeur est alors équipé de deux broches agencées pour se connecter à deux bornes rétractables prévues dans l'oreillette.It is also known from the document EP 1 921 893 an assembly comprising an atrium equipped with an internal battery and a charger arranged to recharge the internal battery of this headset. In this document, the charger has a housing that houses a magnet while the internal battery of the atrium forms a magnetizable element. The charger is then equipped with two pins arranged to connect to two retractable terminals provided in the atrium.

La fabrication de tels moyens de connexion s'avère alors difficile à mettre en oeuvre et onéreuse. Le résultat présente par ailleurs une robustesse limitée.The manufacture of such connection means is then difficult to implement and expensive. The result also has a limited robustness.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Afin de remédier aux inconvénients précités de l'état de la technique, la présente invention propose un nouvel ensemble de connexion, dans lequel la fiche électrique est dépourvue d'aimant et dans lequel les moyens de connexion sont simples et robustes.In order to overcome the aforementioned drawbacks of the state of the art, the present invention proposes a new connection assembly, in which the electrical plug is devoid of a magnet and in which the connection means are simple and robust.

Plus particulièrement, on propose selon l'invention un ensemble de connexion électrique tel que défini dans la revendication 1.More particularly, there is provided according to the invention an electrical connection assembly as defined in claim 1.

La fiche électrique, lorsqu'elle est débranchée, est susceptible d'être déplacée jusqu'à proximité d'un appareil sensible aux champs magnétiques. Grâce à l'invention, elle ne génère alors aucune interférence, si bien que son utilisation ne présente aucun danger.The plug, when disconnected, can be moved to near a magnetic field sensitive device. Thanks to the invention, it does not generate any interference, so that its use is safe.

L'utilisation d'un élément magnétique dans la prise de courant s'avère par ailleurs sans danger puisque, cette prise étant fixée au mur, il est improbable qu'un appareil sensible aux champs magnétiques se retrouve à proximité immédiate de la prise de courant.The use of a magnetic element in the socket is also safe because, since this socket is fixed to the wall, it is unlikely that a device sensitive to magnetic fields is found in the immediate vicinity of the socket .

Enfin, dans l'invention, la stérilité de l'ensemble de connexion est assurée par la position des éléments magnétique et magnétisable (entièrement logés à l'intérieur des enveloppes de la prise de courant et de la fiche électrique), remplissant ainsi une condition sine qua non pour son utilisation en milieu hospitalier.Finally, in the invention, the sterility of the connection assembly is ensured by the position of the magnetic and magnetizable elements (fully housed inside the casings of the socket and the electrical plug), thus fulfilling a condition sine qua non for its use in hospitals.

D'autres caractéristiques avantageuses et non limitatives de l'ensemble de connexion conforme à l'invention sont définies dans les revendications 2 et suivantes.Other advantageous and non-limiting characteristics of the connection assembly according to the invention are defined in claims 2 and following.

Dans la suite de la description, les termes « avant » et « arrière » seront utilisés par rapport aux faces de contact des deux éléments de l'ensemble de connexion électrique selon l'invention. Plus précisément, la face de chaque élément qui sera adaptée à venir en contact contre l'autre élément sera appelée face avant, tandis que la face opposée sera appelée face arrière.In the remainder of the description, the terms "front" and "back" will be used with respect to the contact faces of the two elements of the electrical connection assembly according to the invention. More precisely, the face of each element which will be adapted to come into contact with the other element will be called the front face, while the opposite face will be called the back face.

Sur les figures 1 et 2, on a respectivement représenté une fiche électrique 200 et un mécanisme de prise de courant 100 dans lequel peut s'enficher la fiche électrique 200.On the Figures 1 and 2 , there is shown respectively an electrical plug 200 and a socket mechanism 100 into which the electrical plug 200 can be plugged.

Ce mécanisme de prise de courant 100 forme avec cette fiche électrique 200 un ensemble de connexion 1 (voir figure 3) qui est ici plus particulièrement destiné au milieu hospitalier.This plug-in mechanism 100 forms with this electrical plug 200 a connection assembly 1 (see FIG. figure 3 ) which is here more particularly intended for the hospital environment.

Ici, avantageusement, la fiche électrique 200 est située à l'extrémité d'un câble électrique 300 d'une poire d'appel (non représentée) du type de celles que les patients utilisent pour appeler une infirmière.Here, advantageously, the electrical plug 200 is located at the end of an electric cable 300 of a pear (not shown) of the type that patients use to call a nurse.

Le mécanisme de prise de courant 100 est alors ici monté dans une boîte électrique destinée à être encastrée dans le mur d'une chambre d'hôpital, à proximité du lit d'un patient, et à être connecté au réseau électrique de l'hôpital.The socket mechanism 100 is then mounted in an electrical box intended to be recessed in the wall of a hospital room, near the bed of a patient, and to be connected to the hospital electrical network. .

Pour connecter la poire d'appel à ce réseau électrique, la fiche électrique 200 et le mécanisme de prise de courant 100 comportent chacun des éléments de connexion adaptés à coopérer ensemble.To connect the call bulb to this electrical network, the electrical plug 200 and the socket mechanism 100 each comprise connecting elements adapted to cooperate together.

Comme le montre la figure 1, les éléments de connexion 220 de la fiche électrique 200 sont en partie logés dans une enveloppe 210 en matière isolante, et sont accessibles par la face avant 211 de cette enveloppe 210.As shown in figure 1 , the connection elements 220 of the electrical plug 200 are partly housed in an envelope 210 of insulating material, and are accessible through the front face 211 of the envelope 210.

Comme le montre la figure 2, les éléments de connexion 120 du mécanisme de prise de courant 100 sont également logés dans une enveloppe 110 en matière isolante, et sont accessibles par la face avant 111 de cette enveloppe 110.As shown in figure 2 , the connection elements 120 of the socket mechanism 100 are also housed in an envelope 110 of insulating material, and are accessible through the front face 111 of the envelope 110.

Comme le montrent les figures 4 à 6 et selon une caractéristique particulièrement avantageuse de l'invention, l'enveloppe 110 du mécanisme de prise de courant 100 loge entièrement, à proximité de sa face avant 111, un élément magnétique 130, et l'enveloppe 210 de la fiche électrique 200 loge entièrement, à proximité de sa face avant 211, un élément magnétisable 230 non-magnétique.As shown by Figures 4 to 6 and according to a particularly advantageous feature of the invention, the casing 110 of the socket mechanism 100 fully houses, near its front face 111, a magnetic element 130, and the casing 210 of the electrical plug 200 fully houses , near its front face 211, a magnetizable element 230 non-magnetic.

Ces éléments magnétique et magnétisable 130, 230 sont conçus pour retenir la fiche électrique 200 en position enfichée dans le mécanisme de prise de courant 100, de manière à fermer le circuit électrique entre la poire d'appel et le réseau électrique de l'hôpital.These magnetic and magnetizable elements 130, 230 are designed to hold the electrical plug 200 in position plugged into the socket mechanism 100, so as to close the electrical circuit between the call bulb and the hospital electrical network.

L'utilisation d'un élément magnétique 130 (plutôt que d'un élément mécanique d'encliquetage susceptible de se détériorer) dans le mécanisme de prise de courant 100 permet d'assurer que l'effort de traction nécessaire pour dégager la fiche électrique 200 hors du mécanisme de prise de courant 100 ne varie pas au cours du temps.The use of a magnetic element 130 (rather than a mechanical detent element which may deteriorate) in the socket mechanism 100 ensures that the tensile force required to disengage the electrical plug 200 out of the socket mechanism 100 does not change over time.

La position de ces éléments magnétique et magnétisable 130, 230 (entièrement logés à l'intérieur des enveloppes 110, 210) permet par ailleurs de faciliter leur nettoyage, au bénéfice de la stérilité de l'ensemble de connexion 1.The position of these magnetic and magnetizable elements 130, 230 (fully housed inside the envelopes 110, 210) also makes it easier to clean, to the benefit of the sterility of the connection assembly 1.

Le mécanisme de prise de courant 100 et la fiche électrique 200 sont préférentiellement conçus de manière que, en position enfichée, l'élément magnétique 130 induit sur l'élément magnétisable 230 une force d'attraction comprise entre 20 et 40 Newton.The socket mechanism 100 and the electrical plug 200 are preferably designed so that, in the plugged-in position, the magnetic element 130 induces on the magnetizable element 230 a pulling force of between 20 and 40 Newton.

Cette force d'attraction est suffisamment forte pour permettre de conserver la fiche électrique 200 en position enfichée dans le mécanisme de prise de courant 100 tant qu'aucun effort de traction important n'est exercé sur cette fiche.This attractive force is strong enough to keep the electrical plug 200 in the plugged position in the socket mechanism 100 as long as no significant pulling force is exerted on the plug.

Cette force d'attraction est par ailleurs suffisamment faible pour que, en cas d'urgence (typiquement à la montée ou à la descente du lit du patient), la fiche électrique 200 puisse se déconnecter rapidement sans se détériorer ni détériorer le mécanisme de prise de courant 100.This attraction force is also low enough so that, in an emergency (typically on rising or lowering of the patient's bed), the electrical plug 200 can disconnect quickly without deteriorating or damaging the setting mechanism current 100.

Le mécanisme de prise de courant 100 et la fiche électrique 200 sont préférentiellement conçus de manière que, en position enfichée, les éléments magnétique et magnétisable 130, 230 sont écartés d'une distance, appelée entrefer, comprise entre 1 et 3 millimètres. Cet entrefer est ici égal à 2 millimètres.The socket mechanism 100 and the electrical plug 200 are preferably designed so that, in the plugged position, the magnetic and magnetizable elements 130, 230 are spaced apart by a distance, called the air gap, of between 1 and 3 millimeters. This gap is here equal to 2 millimeters.

Cet entrefer est suffisamment important pour permettre de concevoir une enveloppe 210 de fiche électrique 200 suffisamment épaisse pour être rigide et facilement industrialisable.This gap is large enough to allow to design an envelope 210 electrical plug 200 sufficiently thick to be rigid and easily industrializable.

Il est par ailleurs suffisamment faible pour permettre à l'élément magnétique 130 d'induire sur l'élément magnétisable 230 une force d'attraction optimale sans pour autant présenter des dimensions trop importantes.It is also low enough to allow the magnetic element 130 to induce on the magnetizable element 230 an optimum force of attraction without presenting too large dimensions.

Telle que représentée sur les figures 4 et 5, l'enveloppe 110 du mécanisme de prise de courant 100 est réalisée en trois parties, dont un fond 114, un manchon 113 et un enjoliveur 112.As represented on the figures 4 and 5 , the envelope 110 of the socket mechanism 100 is made in three parts, including a bottom 114, a sleeve 113 and a hubcap 112.

Le fond 114 de l'enveloppe 110 présente une paroi arrière 114A plane et carrée, bordée à l'avant par une nervure périphérique 114B.The bottom 114 of the casing 110 has a flat and square rear wall 114A, bordered at the front by a peripheral rib 114B.

Le manchon 113 est de forme parallélépipédique carrée, avec quatre parois latérales 113B bordées à l'avant, du côté de leurs faces intérieures, par un rebord avant 113A qui délimite une large ouverture circulaire 113G. Les parois latérales 113B portent sur leurs faces externes, à proximité du rebord avant 113A, un trottoir 113C périphérique qui est ici partiellement interrompu par des échancrures.The sleeve 113 is of square parallelepipedal shape, with four side walls 113B lined at the front, on the side of their inner faces, by a front edge 113A which delimits a wide circular opening 113G. The side walls 113B bear on their external faces, near the front edge 113A, a sidewalk 113C device which is here partially interrupted by indentations.

L'enjoliveur 112 comporte quant à lui une plaque frontale 112A plane et carrée, bordée à l'arrière par un bord tombant 112B. La plaque frontale 112A présente en renfoncement un puits 112C traversant d'accueil de la fiche électrique 200, qui est délimité par une paroi latérale de forme cylindrique. Le bord tombant 112B est adapté à s'appliquer par sa tranche arrière sur le trottoir 113C du manchon 113.The hubcap 112 comprises meanwhile a front plate 112A flat and square, bordered at the rear by a falling edge 112B. The front plate 112A recesses a well 112C crossing the home of the electrical plug 200, which is delimited by a cylindrical side wall. The falling edge 112B is adapted to be applied by its rear edge on the sidewalk 113C of the sleeve 113.

Pour son montage sur le fond 114 de l'enveloppe 110, le manchon 113 comporte, sur deux parois latérales 113B opposées, quatre fenêtres 113D. Le fond 114 porte en correspondance quatre pattes d'encliquetage 114D qui s'élèvent à partir de sa nervure périphérique 114B, orthogonalement à sa paroi arrière 114A, et qui portent des griffes adaptées à s'accrocher aux fenêtres 113D du manchon 113.For its mounting on the bottom 114 of the casing 110, the sleeve 113 comprises, on two opposite side walls 113B, four windows 113D. The bottom 114 carries in correspondence four latching lugs 114D which rise from its peripheral rib 114B, orthogonal to its rear wall 114A, and which bear claws adapted to catch on the windows 113D of the sleeve 113.

Pour la fixation de l'enjoliveur 112, le manchon 113 comporte à l'avant du rebord 113C, sur deux parois latérales 113B opposées, quatre rainures 113E dans lesquelles peuvent s'accrocher des griffes 112E prévues en saillie de la face intérieure du bord tombant 112B de l'enjoliveur 112.For fixing the hubcap 112, the sleeve 113 comprises, at the front of the flange 113C, on two opposite side walls 113B, four grooves 113E in which claws 112E can be hooked up projecting from the inner face of the falling edge. 112B of the hubcap 112.

Pour le montage de l'enveloppe 110 du mécanisme de prise de courant 100 dans la boîte électrique rapportée sur le mur de la chambre d'hôpital, le manchon 113 comporte des moyens de fixation sur un support d'appareillage (non représenté) qui est lui-même adapté à être fixé sur la boîte électrique. Ces moyens de fixation comprennent deux pattes d'encliquetage 113F qui sont découpées dans deux parois latérales 113B opposées du manchon 113, à l'arrière du rebord 113C, et qui portent des griffes adaptées à s'accrocher à la face arrière du support d'appareillage lorsque le trottoir 113C du manchon 113 est en appui contre la face avant de ce support d'appareillage.For the mounting of the casing 110 of the socket mechanism 100 in the electrical box attached to the wall of the hospital chamber, the sleeve 113 comprises fixing means on an equipment support (not shown) which is itself adapted to be fixed on the electrical box. These fastening means comprise two latching tabs 113F which are cut in two opposite side walls 113B of the sleeve 113, at the rear of the flange 113C, and which bear claws adapted to hook onto the rear face of the support of FIG. apparatus when the sidewalk 113C of the sleeve 113 bears against the front face of this equipment support.

Lorsqu'elle est assemblée, l'enveloppe 110 du mécanisme de prise de courant 100 loge intérieurement, depuis l'avant vers l'arrière, un circuit imprimé 125, un élément anti-court-circuit 140, l'élément magnétique 130, un moyen de support 150 de l'élément magnétique 130, et un élément de connexion 160 du circuit imprimé 125. Ces différents éléments sont superposés et sont maintenus en position entre la paroi arrière 114A du fond 114 et le rebord avant 113A du manchon 113.When assembled, the envelope 110 of the socket mechanism 100 internally houses, from the front to the back, a printed circuit 125, an anti-short circuit element 140, the magnetic element 130, a support means 150 of the magnetic element 130, and a connection element 160 of the printed circuit 125. These different elements are superimposed and are held in position between the rear wall 114A of the bottom 114 and the front flange 113A of the sleeve 113.

Tel que représenté sur les figures 4 et 5, le circuit imprimé 125 comporte un support 126 en forme de plaque plane carrée, et des pistes 121, 122, 123, 124 en cuivre qui s'étendent sur les deux faces avant et arrière de ce support 126.As shown on the figures 4 and 5 the printed circuit board 125 comprises a flat plane plate support 126 and copper tracks 121, 122, 123, 124 which extend on the two front and rear faces of the support 126.

Le support 126 présente une épaisseur égale à 0,8 millimètre et une largeur égale, au jeu près, à la largeur intérieure du manchon 113. Il est ainsi adapté à se plaquer contre la face arrière du rebord avant 113A du manchon 113. Dans cette position, il ferme l'ouverture circulaire 113G délimitée par le rebord avant 113A du manchon 113 et forme ainsi le fond du puits 112C d'insertion de la fiche électrique 200.The support 126 has a thickness equal to 0.8 millimeters and a width, equal to the play, to the internal width of the sleeve 113. It is thus adapted to be pressed against the rear face of the front flange 113A of the sleeve 113. In this position, it closes the circular opening 113G delimited by the front flange 113A of the sleeve 113 and thus forms the bottom of the well 112C insertion of the electrical plug 200.

Le support 126 du circuit imprimé 125 présente alors en face avant un vernis blanc, qui est visible et qui confère à l'ensemble un aspect propre et net.The support 126 of the printed circuit 125 then has on the front face a white varnish, which is visible and which gives the whole a neat and clean appearance.

Comme le montre la figure 4, sur sa face avant, le support 126 porte quatre pistes 121, 122, 123, 124 s'étendant suivant des cercles concentriques au centre du support. Le diamètre de la piste de plus grand diamètre est inférieur à celui de l'ouverture circulaire 113G délimitée par le rebord avant 113A du manchon 113. De cette manière, ces quatre pistes 121, 122, 123, 124 sont accessibles au fond du puits 112C d'insertion de la fiche électrique 200.As shown in figure 4 , on its front face, the support 126 carries four tracks 121, 122, 123, 124 extending in concentric circles in the center of the support. The diameter of the track of larger diameter is smaller than that of the circular opening 113G delimited by the front flange 113A of the sleeve 113. In this way, these four tracks 121, 122, 123, 124 are accessible at the bottom of the well 112C insertion of the electric plug 200.

Ici, la piste centrale et la piste extérieure correspondent à la phase et au neutre du mécanisme de prise de courant, tandis que les pistes intermédiaires permettent de faire circuler des signaux électriques pour commander l'allumage et l'extinction d'une lumière d'appel dans le local d'infirmières. Le mécanisme de prise de courant 100 est ici alimenté en « très basse tension secourue », c'est-à-dire avec une tension de 24 Volts (30 Volts maximum) continue et un courant maximum de 250 milliAmpères.Here, the central track and the outer track correspond to the phase and the neutral of the socket mechanism, while the intermediate tracks are used to circulate electrical signals to control the switching on and off of a light. call in the local nurses. The socket mechanism 100 is here supplied with "very low voltage backup", that is to say with a voltage of 24 volts (30 volts maximum) continuous and a maximum current of 250 milliamps.

Bien que cela n'apparaisse pas sur la figure 5, sur sa face arrière, le support 126 porte d'autres pistes en cuivre. Ces pistes sont connectées avec celles de la face avant du support 126 par quatre via (terme issu de l'anglais « vertical interconnect access », signifiant en l'espèce « trous métallisés traversants»). Elles sont par ailleurs connectées avec l'élément de connexion 160 par deux nappes 127, qui s'étendent depuis le circuit imprimé 125 jusqu'à cet élément de connexion 160.Although it does not appear on the figure 5 on its rear face, the support 126 carries other copper tracks. These tracks are connected with those of the front face of the support 126 by four via (term derived from the English "vertical interconnect access", meaning in this case "through-through holes"). They are also connected with the connecting element 160 by two layers 127, which extend from the printed circuit 125 to this connection element 160.

Comme le montrent les figures 4 et 5, l'élément de connexion 160 comporte pour sa part un circuit imprimé, appelé circuit imprimé arrière 161, et un bornier 162 qui comporte quatre bornes de connexion (non visibles sur les figures) et qui est fixé à l'arrière du circuit imprimé arrière 161.As shown by figures 4 and 5 the connection element 160 comprises a printed circuit, called the rear printed circuit 161, and a terminal block 162 which has four connection terminals (not visible in the figures). and which is attached to the rear of the rear printed circuit board 161.

Le circuit imprimé arrière 161 comprend un support de dimensions identiques à celles du support du circuit imprimé 125, et des pistes en cuivre qui s'étendent sur la face arrière de ce support.The rear printed circuit 161 comprises a support of dimensions identical to those of the support of the printed circuit 125, and copper tracks which extend on the rear face of this support.

Le bornier 162 comporte ici un socle 167 en matière plastique isolante, qui loge intérieurement les quatre bornes de connexion. Ce socle 167 présente une forme globalement parallélépipédique et est allongé selon un axe parallèle au plan du support du circuit imprimé arrière 161 afin de loger les quatre bornes de connexion en position côte à côte.The terminal block 162 here comprises a base 167 made of insulating plastic material which internally houses the four connection terminals. This base 167 has a generally parallelepiped shape and is elongated along an axis parallel to the plane of the support of the rear printed circuit 161 to accommodate the four connection terminals in side-by-side position.

Ce socle 167 présente en face arrière quatre premiers trous parallèles 164 d'accès aux quatre bornes de connexion, qui permettent d'engager les extrémités dénudées de quatre fils du réseau électrique de l'hôpital dans les quatre bornes de connexion. Quatre fenêtres rectangulaires 114C sont prévues en correspondance dans la paroi arrière 114A du fond 114 de l'enveloppe 110, pour permettre d'accéder aux quatre premiers trous parallèles 164.This base 167 has on the rear face four first parallel holes 164 to access the four connection terminals, which allow to engage the stripped ends of four son of the hospital electrical network in the four connection terminals. Four rectangular windows 114C are provided in correspondence in the rear wall 114A of the bottom 114 of the casing 110, to allow access to the first four parallel holes 164.

Le socle 167 du bornier 162 présente par ailleurs en face latérale quatre seconds trous parallèles 163 d'accès à des alésages taraudés équipant les quatre bornes de connexion. Ces alésages taraudés permettent d'accueillir quatre vis de fixation (non représentées) afin de bloquer les extrémités dénudées des quatre fils dans les quatre bornes de connexion pour les y connecter. Comme le montre la figure 2, l'enveloppe 110 présente alors une ouverture d'accès 110H à ces quatre seconds trous parallèles 163, pour permettre à la pointe d'un tournevis d'accéder aux têtes de ces vis de fixation. Comme le montre la figure 4, cette ouverture d'accès 110H est définie entre deux encoches 113H, 114H, dont l'une est prévue en creux dans la tranche arrière de l'une des parois latérales 113B du manchon 113 de l'enveloppe 110 et dont l'autre est prévue en creux dans la tranche avant de la nervure périphérique 114B du fond 114 de l'enveloppe 110.The base 167 of the terminal block 162 also has on the side face four second parallel holes 163 for accessing tapped bores equipping the four connection terminals. These tapped bores accommodate four fastening screws (not shown) to block the stripped ends of the four son in the four connection terminals to connect them. As shown in figure 2 , the envelope 110 then has an access opening 110H to these four parallel second holes 163, to allow the tip of a screwdriver to access the heads of these fixing screws. As shown in figure 4 this access opening 110H is defined between two notches 113H, 114H, one of which is recessed in the rear edge of one of the side walls 113B of the sleeve 113 of the envelope 110 and the other of which is provided hollow in the front edge of the peripheral rib 114B of the bottom 114 of the casing 110.

Tel que représenté sur les figures 4 et 5, le socle 167 du bornier 162 présente en face avant quatre troisième trous parallèles (non visibles sur les figures), qui permettent à quatre ergots métalliques 165 équipant les quatre bornes de connexion de faire saillie à l'avant du socle 167. Ces quatre ergots métalliques 165 sont engagés dans quatre vias prévus en correspondance dans le support du circuit imprimé arrière 161. Ils permettent alors non seulement de fixer le bornier 162 au circuit imprimé arrière 161, mais également de connecter les quatre bornes de connexion aux pistes de ce circuit imprimé arrière 161.As shown on the figures 4 and 5 , the base 167 of the terminal block 162 has on the front face four third parallel holes (not visible in the figures), which allow four metal pins 165 fitted to the four connection terminals to project at the front of the base 167. These four pins metal 165 are engaged in four vias provided in correspondence in the support of the rear printed circuit 161. They then allow not only to fix the terminal block 162 to the rear printed circuit 161, but also to connect the four connection terminals to the tracks of this rear printed circuit 161.

Ces pistes étant par ailleurs connectées aux nappes 127, les quatre bornes de connexion sont ainsi connectées aux quatre pistes 121, 122, 123, 124 prévues sur la face avant du support du circuit imprimé 125.These tracks being moreover connected to the layers 127, the four connection terminals are thus connected to the four tracks 121, 122, 123, 124 provided on the front face of the support of the printed circuit 125.

Comme le montre la figure 4, l'élément anti-court-circuit 140 comporte une embase 142 en forme de disque, et un pion 141 qui s'étend en saillie du centre de la face avant de l'embase 142.As shown in figure 4 , the anti-short circuit element 140 comprises a disc-shaped base 142, and a pin 141 which protrudes from the center of the front face of the base 142.

L'embase 142 présente un diamètre très inférieur à la largeur du circuit imprimé 125. Elle est ainsi adaptée à s'appliquer contre la face arrière du support 126 du circuit imprimé 125 de telle sorte que le pion 141 s'engage au travers d'une ouverture 128 prévue en correspondance au centre du support 126 du circuit imprimé 125.The base 142 has a diameter much smaller than the width of the printed circuit 125. It is thus adapted to be applied against the rear face of the support 126 of the printed circuit 125 so that the pin 141 engages through an opening 128 provided in correspondence with the center of the support 126 of the printed circuit 125.

Le pion 141 présente à cet effet un diamètre inférieur à celui de la piste 121 de plus petit diamètre et égal, au jeu près, à celui de l'ouverture 128. Il présente par ailleurs une hauteur strictement supérieure à l'épaisseur du support 126 du circuit imprimé 125.The pin 141 has for this purpose a diameter smaller than that of the track 121 of smaller diameter and equal, with the game, to that of the opening 128. It also has a height strictly greater than the thickness of the support 126 of the printed circuit 125.

L'élément anti-court-circuit 140 est réalisé d'une seule pièce en matière plastique isolante.The anti-short circuit element 140 is made in one piece of insulating plastic material.

Ainsi, si un objet métallique quelconque (telle qu'une pièce de monnaie) est attiré par l'élément magnétique 130 contre le circuit imprimé 125, le pion 141 empêchera cet objet de s'appliquer sur ce circuit imprimé 125 et d'entrer simultanément en contact avec plusieurs pistes 121, 122, 123, 124 du circuit imprimé 125. En empêchant cet objet métallique de réaliser un contact électrique entre les pistes 121, 124 de phase et de neutre, l'élément anti-court-circuit 140 peut ainsi éviter l'apparition d'un court-circuit.Thus, if any metal object (such as a coin) is attracted by the magnetic element 130 against the printed circuit 125, the pin 141 will prevent this object from being applied to this printed circuit 125 and to enter simultaneously in contact with several tracks 121, 122, 123, 124 of the printed circuit 125. By preventing this metal object from making an electrical contact between the tracks 121, 124 of phase and neutral, the anti-short circuit element 140 can thus avoid the occurrence of a short circuit.

Comme le montrent les figures 4 et 5, l'élément magnétique 130 est placé entre l'élément de connexion 160 et l'élément anti-court-circuit 140.As shown by figures 4 and 5 the magnetic element 130 is placed between the connection element 160 and the anti-short circuit element 140.

Il comporte ici un aimant 131 permanent et une cage métallique 132 qui est fixée à l'arrière de cet aimant 131.It comprises here a permanent magnet 131 and a metal cage 132 which is fixed to the rear of this magnet 131.

L'aimant 131 présente une forme cylindrique de révolution autour d'un axe A1 orthogonal au plan du support 126 du circuit imprimé 125. Il présente un diamètre de 32 millimètres et une hauteur de 7 millimètres. Il est ainsi logeable dans une enveloppe 110 de mécanisme de prise de courant 100 de taille classique. Il présente ici un trou central traversant 133 d'axe A1, de diamètre légèrement inférieur à celui de l'embase 142 de l'élément anti-court-circuit 140.The magnet 131 has a cylindrical shape of revolution about an axis A1 orthogonal to the plane of the support 126 of the printed circuit 125. It has a diameter of 32 millimeters and a height of 7 millimeters. It is thus accommodable in a casing 110 of socket mechanism 100 of conventional size. It presents here a central through hole 133 of axis A1, of diameter slightly lower than that of the base 142 of the anti-short circuit element 140.

L'aimant 131 est ici de type néodyme.The magnet 131 is here of neodymium type.

Comme cela est représenté en traits discontinus sur la figure 4, il présente une configuration multipolaire frontale. Il comporte donc quatre secteurs angulaires autour de l'axe A1 de mêmes tailles, qui présentent chacun une polarité opposée à celle des deux secteurs angulaires adjacents.As shown in broken lines on the figure 4 it has a front multipolar configuration. It therefore comprises four angular sectors around the axis A1 of the same sizes, each of which has a polarity opposite to that of the two adjacent angular sectors.

Grâce à cette configuration, l'élément magnétisable 230 de la fiche électrique 200 se centre automatiquement dans l'axe A1 de l'aimant 131 lorsqu'il est amené à proximité de celui-ci.With this configuration, the magnetizable element 230 of the electrical plug 200 is automatically centered in the axis A1 of the magnet 131 when brought close to it.

La cage métallique 132 présente pour sa part une forme et des dimensions homologues à celles de l'aimant 131. Elle est fixée à l'aimant 131 dans le prolongement de celui-ci, et permet ainsi d'orienter le flux magnétique issu de l'aimant 131 dans une seule demi-sphère orientée vers l'avant, de manière à optimiser la force d'attraction générée par l'aimant 131 et à protéger l'arrière de la prise de courant 100 du champs magnétique issu de l'aimant 131.The metal cage 132 has a shape and dimensions homologous to those of the magnet 131. It is attached to the magnet 131 in the extension thereof, and thus makes it possible to orient the magnetic flux coming from the magnet 131. 131 magnet in a single half-sphere facing forward, so as to optimize the attractive force generated by the magnet 131 and to protect the back of the socket 100 of the magnetic field from the magnet 131.

Le moyen de support 150 de l'élément magnétique 130 est agencé pour maintenir ce dernier en position fixe dans l'enveloppe 110.The support means 150 of the magnetic element 130 is arranged to hold the latter in a fixed position in the envelope 110.

Comme le montre la figure 5, il comporte à cet effet un berceau 151 d'accueil de l'élément magnétique 130, et des moyens de fixation 152, 157 de ce berceau 151 sur les circuits imprimés 125, 161.As shown in figure 5 , it comprises for this purpose a cradle 151 for receiving the magnetic element 130, and fixing means 152, 157 of this cradle 151 on the printed circuits 125, 161.

Le berceau 151 présente un fond plat 153 de forme globalement rectangulaire, avec deux bords opposés rectilignes et parallèles, et deux autres bords opposés arrondis, circonscrits à un même cercle de diamètre égal à celui de l'élément magnétique 130. Il comporte également deux flasques 154 qui s'élèvent en vis-à-vis à partir de ces deux bords arrondis, sur une hauteur environ égale à celle de l'élément magnétique 130, pour délimiter entre eux un logement d'accueil de cet élément magnétique 130.The cradle 151 has a flat bottom 153 of generally rectangular shape, with two opposite edges rectilinear and parallel, and two other rounded opposite edges, circumscribed to the same circle of diameter equal to that of the magnetic element 130. It also comprises two flanges 154 which rise vis-à-vis from these two rounded edges, on a height approximately equal to that of the magnetic element 130, to delimit between them a housing for receiving this magnetic element 130.

Comme le montre la figure 4, les tranches avant de ces deux flasques 154 sont bordées extérieurement par deux rebords 156 plats, agencés pour s'appliquer contre la face arrière du support 126 du circuit imprimé 125. Chaque rebord 156 comporte un ergot 157 qui s'élève en saillie de sa face avant pour s'engager dans un trou 129 prévu en correspondance dans le support 127 du circuit imprimé 125. Ces ergots 157 permettent ainsi de correctement centrer l'élément magnétique 130 dans l'axe du support 127 du circuit imprimé 125.As shown in figure 4 , the front slices of these two flanges 154 are lined externally by two flanges 156 flat, arranged to be applied against the rear face of the support 126 of the printed circuit 125. Each rim 156 has a lug 157 which projects from its projection. front face to engage in a hole 129 provided in correspondence in the support 127 of the printed circuit 125. These pins 157 and allow to properly center the magnetic element 130 in the axis of the support 127 of the printed circuit 125.

Comme le montre la figure 5, le berceau 151 repose par ailleurs sur le support du circuit imprimé arrière 161 par deux nervures 155 rectilignes et parallèles, qui s'étendent en saillie de la face arrière de son fond plat 153.As shown in figure 5 the cradle 151 also rests on the support of the rear printed circuit 161 by two rectilinear and parallel ribs 155 which project from the rear face of its flat bottom 153.

Il est rigidement fixé sur le circuit imprimé arrière 161 par des moyens d'encliquetage, comportant ici deux pattes d'encliquetage 152. Comme le montre la figure 5, ces deux pattes d'encliquetage 152 s'étendent en longueur à partir de la face arrière du fond plat 153 du berceau 151, orthogonalement à celle-ci, et portent à leurs extrémités libres deux griffes tournées à l'opposé l'une de l'autre. Le support du circuit imprimé arrière 161 comporte en correspondance deux ouvertures circulaires 166 au travers desquelles les pattes d'encliquetage 152 peuvent s'engager de manière que leurs griffes s'accrochent à la face arrière de ce support. Ces pattes d'encliquetage 152 permettent ainsi de centrer et de bloquer l'élément magnétique 130 dans l'axe du support du circuit imprimé arrière 161.It is rigidly fixed on the rear printed circuit 161 by latching means, here comprising two latching lugs 152. As shown in FIG. figure 5 these two latching tabs 152 extend in length from the rear face of the flat bottom 153 of the cradle 151, orthogonally thereto, and carry at their free ends two claws facing away from each other. the other. The support of the rear printed circuit 161 comprises in correspondence two circular openings 166 through which the detent tabs 152 can engage so that their claws cling to the rear face of this support. These latching tabs 152 thus make it possible to center and lock the magnetic element 130 in the axis of the back-printed circuit support 161.

La fiche électrique 200 est pour sa part représentée sur les figures 1 et 6.The electrical plug 200 is for its part represented on the figures 1 and 6 .

Son enveloppe 210 présente globalement une forme de cône droit d'axe de révolution A2, dont le sommet est tronqué.Its envelope 210 generally has a right conical shape of A2 axis of revolution, whose vertex is truncated.

Elle est réalisée en trois parties distinctes, chacune issue de moulage d'une matière plastique isolante. Elle comporte plus particulièrement un capot avant 212, qui forme la base du cône, et un corps arrière 216 constitué de deux parties 213, 214 identiques, qui forme la paroi latérale du cône.It is made of three distinct parts, each resulting from molding of an insulating plastic material. It more particularly comprises a front cover 212, which forms the base of the cone, and a rear body 216 consisting of two parts 213, 214 identical, which forms the side wall of the cone.

Le capot avant 212 présente une paroi frontale 212A en forme de disque d'axe de révolution A2, qui est bordée du côté arrière par un bord tombant 212B cylindrique autour de l'axe de révolution A2.The front cover 212 has a front wall 212A disk-shaped axis of revolution A2, which is bordered on the rear side by a falling edge 212B cylindrical about the axis of revolution A2.

La paroi frontale 212A présente une faible épaisseur, ici égale à 1,2 millimètre, agencée pour que l'entrefer prévu entre les éléments magnétique 130 et magnétisable 230 ait une valeur réduite.The front wall 212A has a small thickness, here equal to 1.2 millimeters, arranged so that the air gap provided between the magnetic elements 130 and magnetizable 230 has a reduced value.

Cette paroi frontale 212A comporte un orifice central 212C de diamètre égal, au jeu près, à celui du pion 141 de l'élément anti-court-circuit 140 du mécanisme de prise de courant 100. De cette manière, la fiche électrique 200 peut être rapportée au fond du puits 112C du mécanisme de prise de courant 100, de telle manière que la face avant 211 de son enveloppe 210 s'applique uniformément contre la face avant du circuit imprimé 125 du mécanisme de prise de courant 100.This front wall 212A has a central orifice 212C of equal diameter, clearance, to that of the pin 141 of the anti-short circuit element 140 of the socket mechanism 100. In this way, the electrical plug 200 can be attached to the bottom of the well 112C of the socket mechanism 100, so that the front face 211 of its casing 210 is uniformly applied against the front face of the circuit board 125 of the socket mechanism 100.

Le bord tombant 212B du capot avant 212 présente pour sa part un diamètre extérieur égal, au jeu près, au diamètre du puits 112C du mécanisme de prise de courant 100. De cette manière, la fiche électrique 200 est adaptée à se centrer automatiquement, par coopération de forme, dans le puits 112C.The falling edge 212B of the front cover 212, for its part, has an outside diameter equal, with play, to the diameter of the well 112C of the socket mechanism 100. In this way, the electrical plug 200 is adapted to be centered automatically, by form cooperation, in well 112C.

Les deux parties 213, 214 du corps arrière 216 de l'enveloppe 210 permettent de raccorder continûment et esthétiquement le capot avant 212 à la face latérale du câble électrique 300.The two parts 213, 214 of the rear body 216 of the casing 210 allow to connect continuously and aesthetically the front cover 212 to the side face of the electric cable 300.

Le sommet tronqué du cône présente à cet effet une ouverture carrée 215 de passage du câble électrique 300.The truncated apex of the cone has for this purpose a square opening 215 for the passage of the electric cable 300.

Afin d'assurer l'étanchéité entre l'ouverture carrée 215 de l'enveloppe 210 et le câble électrique 300, ce dernier est équipé, à proximité de son extrémité libre, d'un joint 310 globalement conique qui, comme le montre la figure 1, est conçu pour prolonger esthétiquement la forme conique de l'enveloppe 210. Comme le montre la figure 6, ce joint 310 présente à mi-hauteur un rétrécissement de section 315 de forme carrée, sur laquelle peut se refermer l'ouverture carrée 215 de l'enveloppe 210.In order to ensure the seal between the square opening 215 of the casing 210 and the electrical cable 300, the latter is equipped, near its free end, with a generally conical seal 310 which, as shown in FIG. figure 1 , is designed to aesthetically extend the conical shape of the envelope 210. As shown in FIG. figure 6 , this joint 310 has at mid-height a narrowing section 315 of square shape, on which can close the square opening 215 of the casing 210.

La base du cône formé par les deux parties 213, 214 du corps arrière 216 de l'enveloppe 210 est par ailleurs fermée par une cloison 214B, 214C qui délimite une ouverture centrale oblongue 217.The base of the cone formed by the two parts 213, 214 of the rear body 216 of the casing 210 is further closed by a partition 214B, 214C which defines an oblong central opening 217.

Les deux parties 213, 214 du corps arrière 216 de l'enveloppe 210 sont adaptées à s'emboîter l'une sur l'autre et à se bloquer dans cette position par l'intermédiaire de moyens d'encliquetage 218, 219.The two parts 213, 214 of the rear body 216 of the casing 210 are adapted to fit one on the other and to lock in this position by means of latching means 218, 219.

Ces moyens d'encliquetage comportent à cet effet deux pattes 218, 219 qui s'élèvent en parallèle, en saillie de la face interne de chaque partie 213, 214 du corps arrière 216 de l'enveloppe 210.

They comprise more precisely, on each part 213, 214 of the rear body 216, a first leg 219 which has on the side of its free end an opening 219A and a second leg 219 which has on the side of its free end a claw 218A adapted to engage in the opening 219A provided on the first leg 219 of the other portion 213, 214 of the rear body 216 of the casing 210.

Le capot avant 212 est adapté à s'emboîter sur le corps arrière 216 de l'enveloppe 210. Son bord tombant 212B présente à cet effet, en creux dans sa face intérieure, une rainure périphérique (non visible sur les figures) dans laquelle peut s'engager une nervure périphérique 213A, 214A prévue en correspondance sur le corps arrière 216 de l'enveloppe 210, en saillie de la face arrière de la cloison 214B, 214C.The front cover 212 is adapted to fit on the rear body 216 of the casing 210. Its falling edge 212B has for this purpose, recessed in its inner face, a peripheral groove (not visible in the figures) in which can engage a peripheral rib 213A, 214A provided in correspondence on the rear body 216 of the casing 210, projecting from the rear face of the partition 214B, 214C.

Les moyens de connexion 220 prévus dans l'enveloppe 210 comportent ici une plaque support 225 de forme rectangulaire.The connection means 220 provided in the envelope 210 here comprise a support plate 225 of rectangular shape.

Cette plaque support 225 porte sur sa face arrière un bornier de connexion 226 dans lequel peut se brancher un élément de connexion 320 prévu en correspondance à l'extrémité du câble électrique 300.This support plate 225 carries on its rear face a connection terminal block 226 in which can be connected a connecting element 320 provided corresponding to the end of the electric cable 300.

Elle porte sur sa face avant quatre connecteurs 221, 222, 223, 224 qui, d'un côté, sont connectés au bornier de connexion 226, et, de l'autre, sont prévus pour être accessibles sur la face avant 211 du capot avant 212 au travers de quatre ouvertures 212D prévues en correspondance dans la paroi frontale 212A de ce capot avant 212.It carries on its front face four connectors 221, 222, 223, 224 which, on one side, are connected to the terminal block 226, and, on the other, are provided to be accessible on the front face 211 of the front cover. 212 through four openings 212D provided in correspondence in the front wall 212A of the front cover 212.

Ces quatre ouvertures 212D sont placées sur quatre cercles qui sont concentriques au centre de la paroi frontale 212A du capot avant 212 et qui présentent des diamètres égaux aux diamètres des pistes 121, 122, 123, 124 prévues sur la face avant du circuit imprimé 125 du mécanisme de prise de courant 100.These four openings 212D are placed on four circles which are concentric in the center of the front wall 212A of the front cover 212 and which have diameters equal to the diameters of the tracks 121, 122, 123, 124 provided on the front face of the printed circuit 125 of the outlet mechanism 100.

De cette manière, lorsque la fiche électrique 200 est engagée dans le puits 112C du mécanisme de prise de courant 100, ses quatre connecteurs 221, 222, 223, 224 viennent respectivement en contact avec les quatre pistes 121, 122, 123, 124 du mécanisme de prise de courant 100, quelle que soit l'orientation de la fiche électrique 200 par rapport au mécanisme de prise de courant 100 autour des axes A1, A2.In this way, when the electrical plug 200 is engaged in the well 112C of the socket mechanism 100, its four connectors 221, 222, 223, 224 respectively come into contact with the four tracks 121, 122, 123, 124 of the mechanism socket 100, regardless of the orientation of the electrical plug 200 relative to the socket mechanism 100 about the axes A1, A2.

Les quatre connecteurs 221, 222, 223, 224 sont ici des connecteurs à pistons. Ils comportent donc chacun une tige conductrice qui coulisse dans un fourreau entre une position rentrée et une position sortie, et qui est automatiquement rappelée en position sortie afin d'assurer un bon contact électrique entre les connecteurs 221, 222, 223, 224 et les pistes 121, 122, 123, 124.The four connectors 221, 222, 223, 224 here are piston connectors. They therefore each comprise a conductive rod which slides in a sleeve between a retracted position and an extended position, and which is automatically recalled in the extended position to ensure good electrical contact between the connectors 221, 222, 223, 224 and the tracks. 121, 122, 123, 124.

Les quatre connecteurs 221, 222, 223, 224 sont ici disposés côte à côte. Il est alors prévu, en saillie de la face arrière de la paroi frontale 212A du capot avant 212 de l'enveloppe 210, une nervure (non visible sur les figures) qui s'étend selon un contour rectangulaire autour des ouvertures 212D et qui forme un logement d'accueil des fourreaux de ces connecteurs 221, 222, 223, 224.The four connectors 221, 222, 223, 224 are here arranged side by side. It is then provided, projecting from the rear face of the front wall 212A of the front cover 212 of the casing 210, a rib (not visible in the figures) which extends in a rectangular contour around the openings 212D and which forms a housing housing the sleeves of these connectors 221, 222, 223, 224.

Cette nervure permet ainsi de maintenir la plaque support 225 à l'arrière de la paroi frontale 212A du capot avant 212, dans l'axe des ouvertures 212D. La plaque support 225 est par ailleurs bloquée dans cette position entre la cloison 213B, 214B du corps arrière 216 de l'enveloppe 210 et l'élément magnétisable 230.This rib thus makes it possible to maintain the support plate 225 at the rear of the front wall 212A of the front cover 212, in the axis of the openings 212D. The support plate 225 is also locked in this position between the wall 213B, 214B of the rear body 216 of the casing 210 and the magnetizable element 230.

Comme le montre la figure 6, cet élément magnétisable 230 présente une forme de rondelle, avec une tranche sensiblement cylindrique de révolution autour de l'axe A2. Il présente ici un diamètre identique à celui de l'élément magnétique 130 du mécanisme de prise de courant 100 et une épaisseur supérieure à 1 millimètre, ici égale à 1,5 millimètre. Grâce à cette forme, le champ magnétique induit par l'élément magnétique 130 boucle parfaitement sur cet élément magnétisable 230, de sorte qu'il exerce une force d'attraction optimale sur celui-ci.As shown in figure 6 this magnetizable element 230 has a washer shape, with a substantially cylindrical slice of revolution about the axis A2. It has here a diameter identical to that of the magnetic element 130 of the socket mechanism 100 and a thickness greater than 1 millimeter, here equal to 1.5 millimeters. Thanks to this shape, the magnetic field induced by the magnetic element 130 perfectly buckles on this magnetizable element 230, so that it exerts an optimum force of attraction thereon.

L'élément magnétisable 230 est réalisé d'une seule pièce en matériau métallique. Il est plus précisément réalisé en acier doux avec un taux de carbone inférieur à 1 %.The magnetizable element 230 is made of a single piece of metal material. It is more precisely made of mild steel with a carbon content of less than 1%.

Il présente ici une ouverture centrale rectangulaire 231, dont les dimensions seront précisées dans la suite de cet exposé.It has here a rectangular central opening 231, the dimensions of which will be specified later in this presentation.

Cette ouverture centrale rectangulaire 231 est prolongée à l'une de ses extrémités par une partie 233 de passage des quatre connecteurs 221, 222, 223, 224. Cette partie 233 présente des dimensions telles que l'élément magnétisable 230 est adapté à s'engager sur la nervure rectangulaire située en saillie de la face arrière de la paroi frontale 212A du capot avant 212 de l'enveloppe 210.This rectangular central opening 231 is extended at one of its ends by a portion 233 through which the four connectors 221, 222, 223, 224 pass. This portion 233 has dimensions such that the magnetizable element 230 is adapted to engage on the rectangular rib projecting from the rear face of the front wall 212A of the front cover 212 of the casing 210.

L'élément magnétisable 230 présente par ailleurs deux orifices circulaires 232, situés de part et d'autre de l'ouverture centrale rectangulaire 231, dont la fonction sera précisée dans la suite de cet exposé.The magnetizable element 230 also has two circular orifices 232, located on either side of the central rectangular opening 231, the function of which will be specified later in this description.

Pour sa fixation dans l'enveloppe 210 de la fiche électrique 200, cet élément magnétisable 230 est adapté à être bloqué contre la face arrière de la paroi frontale 212A du capot avant 212, par des griffes d'encliquetage (non visibles sur les figures) prévues en saillie de la face interne du bord tombant 212B du capot avant 212.For fixing it in the casing 210 of the electric plug 200, this magnetizable element 230 is adapted to be locked against the rear face of the front wall 212A of the front cover 212, by latching claws (not visible in the figures) provided projecting from the inner face of the falling edge 212B of the front cover 212.
