Abstract

The insulating tip (13) may be threaded along part of its length to engage the internal thread on the insulating socket (39), driven by an external screw (11). Alternatively, an internal hooking pin may clip into a complementary with a close action of the contacts (21, 37). The height of the guide elements relative to the contacts is greater in a ratio of 1.15 to 3 than the distance between the sleeve (19, 41) and the corresponding guide element which is about 7-9 mm. The sleeve, guides and contacts are complementary and interweave with one another. The sleeve and guides are pushed towards the exterior to prevent accidental entry by a finger or tool.

Description

L'invention concerne un connecteur électrique basse tension unipolaire, destiné notamment à permettre une alimentation électrique locale provisoire du réseau électrique "E.D.F", lors d'une mise hors circuit de ce dernier. Ce connecteur est en particulier monté en dérivation sur le réseau pour alimenter de façon auxiliaire certains points du réseau, blocs d'immeuble par exemple, lors de la mise hors circuit aval de celui-ci.The invention relates to a low electrical connector unipolar voltage, intended in particular to allow a temporary local power supply to the network electric "E.D.F", when switching off this latest. This connector is in particular mounted in bypass on the network to supply auxiliary power certain points in the network, for example building blocks, when switching it downstream.

L'invention concerne ainsi un nouveau connecteur spécialement conçu pour cette application basée sur la tendance actuelle de l'"E.D.F". de maintenir l'alimentation électrique des usagers et donc éviter de les soumettre à une interruption du réseau.The invention thus relates to a new connector specially designed for this application based on the current trend of "E.D.F". maintain food users and therefore avoid subjecting them to a network interruption.

Un autre objet de l'invention est de proposer un connecteur électrique isolé tant pour sa partie de contact mâle que pour sa partie de contact femelle complémentaire et répondant en particulier à la référence IP 2 X de la norme européenne NF EN 60 529.Another object of the invention is to provide a insulated electrical connector both for its contact part male than for its complementary female contact part and meeting in particular the IP 2 X reference of the standard European NF EN 60 529.

Il est en effet proposé selon l'invention un connecteur électrique basse tension unipolaire, destiné notamment à permettre une alimentation électrique locale de certains points du réseau électrique, à la mise hors circuit aval de ce dernier, caractérisé en ce qu'il comporte une partie de contact mâle et une partie de contact femelle complémentaire, protégées chacune par une jupe périphérique isolante électrique ou analogue, et un élément de guidage de l'assemblage des parties de contact mâle et femelle pour leur raccordement électrique, cet élément étant situé sensiblement en partie médiane du connecteur et donc desdites parties de contact, ledit élément de guidage consistant en un embout isolant électrique formé sur l'une des parties de contact et en une douille isolante électrique complémentaire, formée sur l'autre partie de contact et destinée à recevoir l'embout, lesdits embout et douille isolants électriques s'étendant respectivement pour chaque partie de contact, relativement à leur contact proprement dit, à une hauteur déterminée, sensiblement au niveau de l'extrémité de leur jupe périphérique et fonction respectivement de la distance entre la jupe et l'élément de guidage correspondant.A connector is indeed proposed according to the invention unipolar low voltage electric, intended in particular for allow local power to some points of the electrical network, at the downstream shutdown of the latter, characterized in that it comprises a part of male contact and female contact part complementary, each protected by a peripheral skirt electrical insulator or the like, and a guide element the assembly of the male and female contact parts for their electrical connection, this element being located substantially in the middle part of the connector and therefore of said contact parts, said guide member consisting of an electrical insulating tip formed on one contact parts and an electrical insulating sleeve complementary, formed on the other contact part and intended to receive the end piece, said end piece and socket electrical insulators extending respectively for each contact part, relative to their actual contact said, at a determined height, substantially at the level of the end of their peripheral and functional skirt respectively of the distance between the skirt and the element of corresponding guidance.

Ladite hauteur de l'élément de guidage relativement au contact est plus importante, dans un rapport de 1,15 à 3, que la distance entre la jupe et l'élément de guidage correspondant, laquelle est de l'ordre de 7 à 9 mm.Said height of the guide element relative to the contact is more important, in a ratio of 1.15 to 3, that the distance between the skirt and the guide element corresponding, which is of the order of 7 to 9 mm.

Il résulte de cette disposition, qu'en raison de la profondeur du contact relativement à la face d'ouverture de la partie de contact, contenant l'extrémité supérieure de l'élément de guidage isolant et l'extrémité supérieure de la jupe isolante, et de la distance entre la jupe et l'élément de guidage isolant correspondant (7-9 mm), qu'une sécurité d'isolation électrique, contre l'intrusion de doigts ou d'outils accidentellement par une personne, est réalisée.It follows from this provision that, due to the contact depth relative to the opening face of the contact part, containing the upper end of the insulating guide element and the upper end of the insulating skirt, and the distance between the skirt and the element corresponding insulating guide (7-9 mm), only safety electrical insulation, against intrusion of fingers or of tools accidentally by a person, is carried out.

Le connecteur possède avantageusement une symétrie axiale et le contact proprement dit de chaque partie de contact est respectivement un anneau métallique plan, délimité extérieurement par une jupe périphérique circulaire isolante et intérieurement par un élément de guidage isolant cylindrique en position centrale. Ladite distance entre la jupe et l'élément de guidage est donc constante, de même que la profondeur du contact relativement à la face d'ouverture de la partie de contact correspondante.The connector advantageously has a symmetry axial and the actual contact of each part of contact is respectively a plane metal ring, externally delimited by a circular peripheral skirt insulating and internally by an insulating guide element cylindrical in central position. Said distance between the skirt and the guide element is therefore constant, as is the depth of the contact relative to the opening face of the corresponding contact part.

Le connecteur est avantageusement à raccordement de type vissé, portant sur l'une des parties de contact un embout de guidage isolant, fileté sur au moins une partie de sa longueur et s'engageant dans un taraudage interne complémentaire de l'autre partie de contact, coaxialement à sa douille isolante.The connector is advantageously with type connection screwed, bearing on one of the contact parts an end piece insulating guide, threaded on at least part of its length and engaging in internal tapping complementary to the other contact part, coaxially with its insulating sleeve.

Naturellement, l'élément de verrouillage du contact peut également être à broche de crochetage interne axiale formée sur l'une des parties de contact, fonctionnant par encliquetage dans un alésage complémentaire de l'autre partie de contact avec rappel serré des contacts, ou encore à bras externes de crochetage d'une des parties de contact sur l'autre.Naturally, the contact locking element can also be formed with internal axial hook pin on one of the contact parts, operating by snapping into a complementary bore of the other contact part with tight reminder of the contacts, or with external hooking arms of one of the contact parts on the other.

La partie de contact portant l'embout de guidage isolant est avantageusement une partie mâle mobile, la partie femelle portant ainsi la douille isolante, et le raccordement vissé du connecteur est réalisé par une manoeuvre externe d'une vis sur la partie mâle entraínant l'embout.The contact part carrying the insulating guide tip is advantageously a movable male part, the part female thus carrying the insulating sleeve, and the screw connection of the connector is achieved by a external operation of a screw on the driving male part the mouthpiece.

Ledit élément de guidage de l'assemblage (embout ou douille) peut être monté coulissant vers l'intérieur, étant rappelé vers l'extérieur à un effort de tarage déterminé, (1-10 daN) suffisant pour prévenir toute intrusion accidentelle d'un doigt ou d'un outil par une personne.Said guide element of the assembly (end piece or socket) can be mounted sliding inwards, being recalled outwards at a determined taring effort, (1-10 daN) sufficient to prevent any intrusion accidental finger or tool by a person.

De même, ladite jupe protégeant la périphérie du contact proprement dit peut être montée coulissante vers l'intérieur, étant rappelée vers l'extérieur à un effort de tarage déterminé (1-10 daN).Similarly, said skirt protecting the periphery of the contact itself can be slidably mounted towards the interior, being recalled outward to an effort of determined calibration (1-10 daN).

De préférence, la partie de contact femelle fait partie d'un boítier d'embase et comporte une jupe d'enveloppe du contact, massique et fixe et une douille isolante mobile, et la partie de contact mâle comporte une jupe cylindrique coulissante et un embout isolant monté rotatif en position de hauteur fixe, de telle sorte qu'au raccordement de ces parties pour la mise en service du connecteur, la jupe coulissante vienne porter avec recul sur la jupe massique de la partie femelle ou sur son contact proprement dit et la douille de la partie femelle porte avec recul sur le contact proprement dit de l'élément de contact mâle.Preferably, the female contact part is part of a base box and comprises an envelope skirt of the contact, mass and fixed and a movable insulating sleeve, and the male contact part has a cylindrical skirt sliding and an insulating tip rotatably mounted in position fixed height, so that at the connection of these parts for putting the connector into service, the skirt sliding come wear with hindsight on the mass skirt of the female part or on its actual contact and the socket of the female part door with recoil on the contact proper of the male contact element.

L'un seulement des éléments de jupe ou de guidage d'une même partie de contact peut être coulissant.Only one of the skirt or guide elements of a same contact part can be sliding.

Ces éléments peuvent naturellement être fixes et s'interpénétrer l'un dans l'autre dans des logements complémentaires des parties de contact au raccordement électrique.These elements can naturally be fixed and interpenetrate into each other in housing complementary to the contact parts at the connection electric.

L'invention est illustrée ci-après à l'aide d'un exemple de réalisation et en référence aux dessins annexés, sur lesquels :

  • la figure 1 est une vue en coupe d'un connecteur selon l'invention, les parties de contact étant détachées axialement l'une de l'autre,
  • la figure 2 est une vue d'un connecteur selon l'invention en position raccordée de service et
  • la figure 3 est une vue d'une variante de réalisation de la partie de contact mobile ou fiche.
The invention is illustrated below using an embodiment and with reference to the accompanying drawings, in which:
  • FIG. 1 is a sectional view of a connector according to the invention, the contact parts being axially detached from one another,
  • FIG. 2 is a view of a connector according to the invention in the connected service position and
  • Figure 3 is a view of an alternative embodiment of the movable contact part or plug.

Le connecteur électrique représenté comporte une partie de contact mâle mobile ou fiche 1 et une partie de contact femelle fixe ou embase 3 solidaire d'un boítier électrique de raccordement au réseau électrique "E.D.F". (non représenté).The electrical connector shown has a part movable male contact or plug 1 and a contact part fixed female or base 3 secured to an electrical box of connection to the electrical network "E.D.F". (no represented).

La partie de contact mâle 1 est en forme de L renversé, comportant une partie avant allongée cylindrique 5 (branche longue du L) et une partie arrière 7 correspondant à la petite branche du L, disposée transversalement par rapport à la partie allongée 5. Cette partie arrière 7 gainée isolante est reliée à un câble électrique 9. Coaxialement à la partie avant 5 et sur sa partie arrière est disposée une vis de manoeuvre 11. Cette vis est solidaire d'un embout de guidage isolant médian 13 débouchant sur la face avant 15.The male contact part 1 is in the shape of an inverted L, comprising an elongated cylindrical front part 5 (branch long L) and a rear part 7 corresponding to the small branch of L, arranged transversely to the elongated part 5. This insulated sheathed rear part 7 is connected to an electrical cable 9. Coaxially to the part front 5 and on its rear part is arranged a screw operation 11. This screw is integral with a guide tip middle insulator 13 opening onto the front face 15.

La partie avant 5 comprend un fourreau métallique conducteur interne 17, en cuivre, relié à la branche arrière 7, et un manchon isolant électrique externe 19 ou jupe, qui est monté coulissant sur le fourreau conducteur interne 17. A l'extrémité du fourreau interne est formé le contact proprement dit 21 qui consiste en un anneau plan coaxial au fourreau et de diamètre élargi relativement à celui-ci.The front part 5 includes a metal sheath internal conductor 17, made of copper, connected to the rear branch 7, and an external electrical insulating sleeve 19 or skirt, which is slidably mounted on the internal conductive sheath 17. At the end of the internal sheath is formed the contact proper 21 which consists of a coaxial plane ring at sheath and of enlarged diameter relative thereto.

Ce contact annulaire peut naturellement avoir une section de configuration géométrique variable.This annular contact can naturally have a variable geometric configuration section.

Un ressort hélicoïdal 23 est monté entre le fourreau 17 et le manchon 19, s'appliquant par ses extrémités, respectivement sur une portée avant 25 du manchon et sur une bague arrière 27 fixée sur le fourreau, sensiblement en sa partie médiane. Ce faisant, le ressort 23 maintient le manchon 19 à un effort de tarage déterminé par exemple 5 daN, sensiblement au niveau de l'embout isolant 13 (fixe en hauteur), permettant son coulissement arrière à l'assemblage sur la partie de contact femelle 3, avec rappel vers l'avant.A helical spring 23 is mounted between the sheath 17 and the sleeve 19, applying by its ends, respectively on a front surface 25 of the sleeve and on a rear ring 27 fixed on the sheath, substantially in its middle part. In doing so, the spring 23 maintains the sleeve 19 at a determined taring force for example 5 daN, substantially at the level of the insulating end piece 13 (fixed in height), allowing its rear sliding at assembly on the female contact part 3, with reminder forward.

La vis 11 qui s'étend en longueur en une ou deux parties jusqu'à l'embout 13 comporte une partie filetée 29 en arrière de son téton d'extrémité isolant électrique 31, destinée à venir en prise dans un taraudage complémentaire 33 de la partie femelle 3. La vis est donc entraínée avec l'embout 13, en vue de raccorder de façon serrée la partie de contact mâle 1 sur la partie de contact femelle 3.The screw 11 which extends in length in one or two parts up to the end piece 13 has a threaded portion 29 in rear of its electrical insulating end stud 31, intended to engage in a complementary thread 33 of the female part 3. The screw is therefore driven with the end piece 13, in order to tightly connect the part male contact 1 on the female contact part 3.

Le contact 21 est inséré dans la partie avant 5 à une profondeur d'environ 21 mm relativement à l'extrémité du manchon (sa jupe) et à celle de l'embout, celui-ci et le manchon étant disposés avec leur extrémité sensiblement sur un même plan avant. L'embout 13 positionné dans l'axe de la partie avant 5 a un diamètre de téton isolant 31 de 9 mm. La distance entre le téton 31 et le manchon 19 est de 7,5 mm, en tout point radial, empêchant ainsi toute intrusion accidentelle d'un doigt jusqu'au niveau du contact 21.Contact 21 is inserted in the front part 5 at a depth of about 21 mm relative to the end of the sleeve (its skirt) and that of the nozzle, this and the sleeve being arranged with their end substantially on the same front plane. The nozzle 13 positioned in the axis of the front part 5 has an insulating nipple diameter 31 of 9 mm. The distance between the stud 31 and the sleeve 19 is 7.5 mm, at any radial point, thus preventing any intrusion accidental finger contact up to contact level 21.

La partie de contact femelle 3, disposée sous la partie de contact mâle 1 à la figure 1, est complémentaire de cette dernière, recevant celle-ci axialement au raccordement électrique du connecteur. Elle comporte une plaque de contact avant 35 en cuivre découvrant un anneau plan de contact 37 enfoncé entre une douille cylindrique isolante axiale 39 et une jupe isolante axiale avant 41 enveloppant la plaque 35. La douille 39 a un diamètre interne légèrement supérieur à celui de l'embout 13 et guide l'introduction de ce dernier au raccordement électrique du connecteur.The female contact part 3, arranged under the part of male contact 1 in FIG. 1, is complementary to this last, receiving it axially at the connection connector. It has a plate of front contact 35 in copper revealing a flat ring of contact 37 inserted between an insulating cylindrical socket axial 39 and a front axial insulating skirt 41 enveloping the plate 35. The socket 39 has an internal diameter slightly greater than that of the end piece 13 and guides the introduction of the latter to the electrical connection of the connector.

Elle comporte un corps arrière cylindrique isolant 43 appliqué sur la face arrière de la plaque de contact 35, et sur lequel est monté axialement (fixé au moyen de vis arrière 45) un fût métallique cylindrique 47. Dans ce fût 47 est formé ledit taraudage 33 recevant l'embout 13 et la partie filetée 29 de la vis 11 de la partie mâle, à l'arrière de la douille 39. Celle-ci est montée coulissante dans le corps arrière 43, autour du fût central arrière 47. Un ressort hélicoïdal 49 appliqué par ses extrémités, respectivement, au niveau d'un pied de fût 51 et sur une portée élargie externe 53 de la douille (sensiblement dans sa partie médiane) permet le rappel de celle-ci vers l'avant, sensiblement au niveau de la jupe 41 et à un effort de tarage déterminé. La distance entre la douille et la jupe (8,5 mm), de même que la profondeur du contact relativement à la face avant (12 mm) et le tarage en rappel de la douille (5 daN) empêchent toute intrusion accidentelle d'un doigt ou d'un outil par une personne.It has a cylindrical insulating rear body 43 applied to the rear face of the contact plate 35, and on which is axially mounted (fixed with screws rear 45) a cylindrical metal barrel 47. In this barrel 47 is formed said thread 33 receiving the tip 13 and the threaded part 29 of the screw 11 of the male part, the rear of the socket 39. It is slidably mounted in the rear body 43, around the rear central barrel 47. A helical spring 49 applied by its ends, respectively, at the base of a bole 51 and on a external enlarged seat 53 of the socket (substantially in its middle part) allows the recall of it towards the front, substantially at the level of the skirt 41 and at an effort set taring. The distance between the socket and the skirt (8.5 mm), as well as the relatively deep contact at the front (12 mm) and the taring as a reminder of the socket (5 daN) prevent accidental intrusion of a finger or of a tool by one person.

L'accouplement du connecteur est représenté à la figure 2. Il est obtenu de façon simple en introduisant axialement la partie de contact mâle 1 dans la partie femelle 3, avec introduction de l'embout 13 dans la douille 39. La partie filetée 29 venant en contact avec le taraudage 33, la vis 11 est entraínée en rotation au moyen d'une clef de manoeuvre agissant sur sa tête supérieure et serrée jusqu'au blocage. Ce faisant, les contacts (21, 37) des parties mâle et femelle, complémentaires l'un de l'autre, s'appliquent fermement l'un sur l'autre, la douille 39 venant en recul sur le contact 21 de la partie mâle et de même le manchon 19, introduit dans la jupe 41 de l'embase vient en recul sur le contact 37 de la partie femelle.The connector coupling is shown in the figure 2. It is obtained in a simple way by introducing axially the male contact part 1 in the female part 3, with introduction of the nozzle 13 into the socket 39. The part threaded 29 coming into contact with the internal thread 33, the screw 11 is rotated by means of an operating key acting on its upper head and tightened until it locks. In doing so, the contacts (21, 37) of the male parts and female, complementary to each other, apply firmly on each other, the socket 39 receding on contact 21 of the male part and likewise the sleeve 19, inserted into the skirt 41 of the base comes back on contact 37 of the female part.

A la déconnexion des parties de contact 1, 3, la douille 39 et le manchon 19 reprennent leur position d'origine respective précédemment précisée.When the contact parts 1, 3 are disconnected, the socket 39 and the sleeve 19 return to their original position respective previously specified.

Naturellement, de nombreuses variantes peuvent entrer dans le cadre de l'invention. Ainsi, la douille peut être montée sur la partie mâle mobile et l'embout inversement sur la partie femelle. En outre, ces éléments peuvent être mobiles ou fixes, de même que les jupes comme mentionné dans la partie préambule du texte.Naturally, many variants can enter in the context of the invention. So the socket can be mounted on the mobile male part and vice versa the female part. In addition, these elements can be mobile or fixed, as well as the skirts as mentioned in the preamble part of the text.

Enfin, il est intéressant de prévoir que la partie mobile de contact ou fiche soit constituée en deux parties, une partie avant 1a comprenant le corps de fiche et une partie arrière 1b attachée au câble, la partie avant 1a étant montée rotative sur la partie arrière 1b avec un contact rotatif par lamelles 50 entre celles-ci, cette disposition autorisant le libre débattement du câble 9 attenant à la fiche sans agir sur le corps de fiche au risque de désserrer la liaison vissée de la fiche relativement à la douille avec grave préjudice sur le contact.Finally, it is advantageous to provide that the movable contact part or plug is made up of two parts, a front part 1 a comprising the plug body and a rear part 1 b attached to the cable, the front part 1 a being rotatably mounted on the rear part 1b with a rotary contact by strips 50 between them, this arrangement authorizing the free movement of the cable 9 attached to the plug without acting on the plug body at the risk of loosening the screwed connection of the plug relative to the socket with serious damage on contact.
