Description
L'invention concerne un connecteur électrique unipolaire à contacts en bout de préférence pour courants de fortes puissances.The invention relates to a unipolar electrical connector with end contacts, preferably for high power currents.
Pour répondre aux normes en vigueur en vue d'assurer la sécurité des personnes et des biens, les appareils électriques doivent offrir un degré de protection minimum contre l'accès aux pièces sous tension lorsque la tension d'utilisation est supérieure à 50 volts.To meet current standards to ensure the safety of people and property, electrical devices must provide a minimum degree of protection against access to live parts when the operating voltage is greater than 50 volts.
Pour vérifier qu'une telle protection est respectée, on utilise un doigt d'épreuve articulé défini selon une norme.To verify that such protection is respected, an articulated test finger defined according to a standard is used.
Les essais consistent à ne pas pouvoir réaliser un contact entre le doigt d'épreuve normalisé et les parties sous tension de l'appareil à tester en tentant d'introduire le doigt d'épreuve dans toutes les positions possibles.The tests consist in not being able to make a contact between the standardized test finger and the live parts of the apparatus to be tested by attempting to introduce the test finger in all possible positions.
Dans le domaine des connecteurs, une protection peut être obtenue en protégeant chaque contact sous tension par un volet ou en le plaçant en retrait dans une enveloppe isolante afin que le doigt d'épreuve ne puisse pas l'atteindre.In the field of connectors, protection can be obtained by protecting each contact under tension by a shutter or by placing it indented in an insulating envelope so that the test finger can not reach it.
Toutefois, dans le cas des courants forts, c'est-à-dire de forte intensité (par exemple supérieure à 200 Ampères) et utilisant des tensions supérieures à 50 volts, les conducteurs et les éléments de contact dans les appareils connus présentent des sections importantes de passage du courant, et le respect de la norme est difficile puisque le diamètre des éléments de contact devient proche ou supérieur au diamètre maximum du doigt d'épreuve.However, in the case of strong currents, that is to say high intensity (for example greater than 200 amperes) and using voltages greater than 50 volts, the conductors and the contact elements in known devices have sections significant current flow, and compliance with the standard is difficult since the diameter of the contact elements becomes close to or greater than the maximum diameter of the test finger.
C'est pourquoi jusqu'à présent pour de tels courants et plus particulièrement pour les connecteurs unipolaires, une solution à broche et alvéole cylindriques particulière a été imaginée.This is why so far for such currents and more particularly for unipolar connectors, a special pin and cell solution has been devised.
Dans cette solution, contrairement aux prises de courant industrielles, les contacts sous tension sont les broches dont les extrémités sont protégées par un isolant, comme par exemple dans le mode de réalisation décrit dans le brevet
De la sorte, la connexion électrique entre la broche sous tension et l'alvéole conjuguée peut s'effectuer sur une partie de la broche non accessible par le doigt d'épreuve.In this way, the electrical connection between the spindle under tension and the conjugate cavity can be made on a part of the pin not accessible by the test finger.
Il est clair qu'une telle solution est inadaptée aux contacts en bout pour lesquels par définition la connexion électrique s'effectue entre l'extrémité d'une broche de contact et un contact élastique mobile sous pression, de telle sorte que l'extrémité de la broche ne peut évidemment pas être isolée.It is clear that such a solution is unsuitable for end contacts for which by definition the electrical connection is made between the end of a pin contact and a movable elastic contact under pressure, so that the end of the spindle obviously can not be isolated.
C'est pourquoi, pour les courants de fortes intensités qui utilisent des sections de conducteurs importantes, il était apparu impossible d'imaginer des contacts en bout du fait que les broches auraient des dimensions supérieures au doigt d'épreuve.Therefore, for currents of high intensities that use large conductor sections, it appeared impossible to imagine end contacts that the pins would have dimensions greater than the test finger.
Le brevet
Dans le but notamment d'assurer le respect de la norme du doigt d'épreuve, l'invention propose une autre solution.In particular in order to ensure compliance with the test finger standard, the invention proposes another solution.
Le connecteur électrique unipolaire à contacts en bout selon l'invention est formé d'un socle actif et d'une fiche munie d'une broche de contact qui est destinée à pénétrer dans le socle pour coopérer avec un contact élastique aménagé dans celui-ci comme décrit dans le brevet
De la sorte, on peut notamment prévoir une dimension des petits côtés pour l'ouverture de passage qui empêche toute pénétration du doigt d'épreuve.In this way, it is possible in particular to provide a dimension of the short sides for the passage opening which prevents any penetration of the test finger.
Les connecteurs unipolaires sont généralement utilisés par ensemble, chaque connecteur étant destiné à constituer un élément de connexion distinct et spécifique, comme par exemple un ensemble de cinq connecteurs dont l'un est destiné à constituer une prise de terre, un autre le neutre, et les trois autres des connexions de phases.The unipolar connectors are generally used together, each connector being intended to constitute a separate and specific connection element, such as for example a set of five connectors, one of which is intended to form a grounding, another the neutral, and the other three phase connections.
Dans ce cas, il est évidemment primordial que chaque fiche se connecte avec son socle correspondant.In this case, it is obviously essential that each card connects with its corresponding base.
Des simples rappels de couleurs peuvent s'avérer insuffisants alors que l'invention permet un véritable détrompage qui interdit toute connexion erronée.Simple reminders of colors may be insufficient while the invention allows a true coding that prohibits any false connection.
A cet effet, selon un mode de réalisation, la broche de la fiche est entourée par un manchon cylindrique dans lequel vient s'introduire le disque de protection du socle, ledit manchon comportant sur sa paroi interne une nervure ou respectivement une entaille axiale, destinée à coopérer avec une entaille ou respectivement une nervure axiale correspondante aménagée à la périphérie du disque de protection du socle, les décalages angulaires étant égaux entre, d'une part, un plan longitudinal médian de la broche de la fiche parallèle à ses grands côtés avec un plan diamétral au manchon de ladite fiche passant par la nervure ou l'entaille dudit manchon et, d'autre part, un plan longitudinal médian de l'ouverture de passage du disque de protection du socle parallèle aux grands côtés dudit passage avec un plan diamétral du disque de protection passant par l'entaille ou respectivement la nervure de celui-ci.For this purpose, according to one embodiment, the spindle of the plug is surrounded by a cylindrical sleeve into which is introduced the protective disk of the base, said sleeve having on its inner wall a rib or axial slot respectively, intended to cooperate with a notch or respectively a corresponding axial rib formed at the periphery of the base protection disk, the angular offsets being equal between, on the one hand, a median longitudinal plane of the pin of the plug parallel to its long sides with a diametral plane to the sleeve of said plug passing through the rib or the notch of said sleeve and, secondly, a median longitudinal plane of the passage opening of the protective disc of the base parallel to the long sides of said passage with a plane diametrical protective disk passing through the notch or respectively the rib thereof.
Par exemple les décalages angulaires précités peuvent être sensiblement égaux à 30° ou un multiple de 30°. Les décalages pour cinq connecteurs distincts pouvant alors être respectivement de 30°, 60°,90°, 120° et 150°.For example, the aforementioned angular offsets may be substantially equal to 30 ° or a multiple of 30 °. The offsets for five separate connectors can then be respectively 30 °, 60 °, 90 °, 120 ° and 150 °.
Il est ainsi impossible d'accoupler une fiche quelconque avec un autre socle que celui pour lequel elle est destinée.It is thus impossible to couple any plug with another base than that for which it is intended.
Selon un mode réalisation le manchon de la fiche est pourvu d'un piston rétractable élastiquement destiné à venir au contact d'une collerette du socle et s'enclencher, après rotation de la fiche, dans une encoche de ladite collerette en position de connexion des contacts du socle et de la fiche afin d'empêcher toute rotation et donc toute déconnexion intempestive.According to one embodiment, the sleeve of the plug is provided with an elastically retractable piston intended to come into contact with a collar of the base and to engage, after rotation of the plug, in a notch of said collar in the connection position of the contacts of the base and the plug in order to prevent any rotation and therefore any inadvertent disconnection.

Le socle est en outre muni à son extrémité d'un disque de protection 5.The base is further provided at its end with a protective disc 5.
La broche 3 de la fiche présente une section droite sensiblement rectangulaire comme on peut notamment le voir sur les
Par ailleurs dans le mode de réalisation représenté la broche 3 de la fiche est pourvue de deux ergots latéraux 7 (
L'ouverture de passage 6 du disque de protection du socle comporte sur ses petits côtés des encoches 9 (
La broche 3 de la fiche est en outre entourée par un manchon cylindrique 10 dans lequel vient s'introduire le disque de protection 5 du socle comme le montre plus particulièrement la
On peut voir sur les
De manière correspondante le disque de protection 5 du socle est pourvu à sa périphérie d'une entaille 12 axiale comme le montrent bien les
Si dans le mode de réalisation représenté on a prévu une nervure sur la fiche et une entaille sur le socle il pourrait bien sûr s'agir de l'inverse.If in the embodiment shown there is provided a rib on the plug and a notch on the base it could of course be the opposite.
Comme le montrent bien les
De la sorte on crée un véritable détrompage qui permet d'interdire toute connexion d'une fiche et d'un socle incompatibles entre eux.In this way we create a real fool that allows to prohibit any connection of a plug and a base incompatible with each other.

De la sorte, on verrouille en rotation la fiche et le socle qui ne peuvent être déverrouillée que par rétractation du piston 13 au moyen éventuellement d'un outil spécial.In this way, it locks in rotation the plug and the base that can be unlocked only by retraction of the
D'autres particularités sont bien sûr prévues, comme par exemple un joint d'étanchéité aménagé sur le socle ou encore un couvercle destiné à venir recouvrir l'extrémité du socle et obturer ainsi son ouverture de passage 6 lorsque la fiche et le socle sont séparés.Other features are of course provided, such as a seal fitted on the base or a cover intended to cover the end of the base and thus close its
