Description

Connecteur électrique unipolaire à contacts en bout.  Unipolar electrical connector with end contacts.
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 US 3,662,296.  In this solution, unlike industrial power outlets, the live contacts are the pins whose ends are protected by an insulator, as for example in the embodiment described in US Patent 3,662,296.
De la sorte, la connexion électrique entre la broche sous tension et l'alvéole conjuguée peut s'effectuer sur une partie dë la broche non accessible par le doigt d'épreuve.  In this way, the electrical connection between the energized pin and the conjugate socket can be performed 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 EP-1 518 299 au nom du même demandeur décrit toutefois un connecteur à contact en bout particulier pour courants de fortes intensités.  EP-1,518,299 in the name of the same applicant, however, discloses a particular end contact connector for currents of high intensity.
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 EP-1 518 299 précité, ou encore dans le brevet FR- 1 398 945 également au nom du demandeur, au moins la partie pénétrante de la broche de contact de la fiche présentant une section droite de forme générale sensiblement rectangulaire et le socle étant en outre muni à son extrémité d'un disque de protection dans lequel est ménagée une ouverture de passage de section rectangulaire correspondante à la section droite de la broche de la fiche, mais qui est par contre remarquable en ce que les petits côtés de la broche rectangulaire comportent des ergots destinés à coopérer avec des rampes du socle pour un verrouillage du type à baïonnette de la fiche dans le socle, tandis que l'ouverture rectangulaire de passage du disque de protection du socle comporte sur ses petits côtés des encoches pour le passage desdits ergots.  The unipolar electrical connector with end contacts according to the invention is formed of an active base and a plug provided with a contact pin which is intended to penetrate into the base to cooperate with an elastic contact arranged therein as described in the aforementioned EP-1,518,299, or in the patent FR-1,398,945 also in the name of the applicant, at least the penetrating portion of the contact pin of the plug having a cross section of substantially rectangular general shape and the base being further provided at its end with a protective disc in which is formed a passage opening of rectangular section corresponding to the cross section of the pin of the plug, but which is cons remarkable in that the small sides of the rectangular pin have lugs for cooperating with ramps of the base for locking bayonet type of the plug in the base, while the opening Rectangular passage of the protection disc of the base has on its short sides notches for the passage of said lugs.
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. 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. Simple reminders of colors may be insufficient while the invention allows a true coding that prohibits any false connection. 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 décalage's 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 °. Shifts for five separate connectors can then be 30 °, 60 °, 90 °, 120 ° and 150 ° respectively.
II 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.
L'invention sera bien comprise à la lecture de la description qui va suivre et qui se réfère aux dessins annexés dans lesquels : - La figure 1 montre avec arrachement un connecteur selon l'invention dont le socle et la fiche sont en position prêts à être accouplés,  The invention will be better understood on reading the description which follows and which refers to the appended drawings in which: FIG. 1 shows broken away a connector according to the invention whose base and the plug are in position ready to be mated,
La figure 2 montre en perspective le socle de connexion, - La figure 3 montre également en perspective le socle de connexion mais sans son disque de protection, FIG. 2 shows in perspective the connection base, - FIG. 3 also shows in perspective the connection base but without its protection disk,
La figure 4 montre la fiche en vue frontale, - La figure 5 montre la fiche de la figure 4 en perspective. - Les figures 6A à 6E représentent en vues frontales cinq socles de connexion distincts destinés chacun à s'accoupler avec une fiche correspondante non représentée. Figure 4 shows the card in front view, - Figure 5 shows the card of Figure 4 in perspective. - Figures 6A to 6E show in front views five separate connection bases each intended to mate with a corresponding plug not shown.
Un connecteur selon l'invention comporte un socle 1 actif, c'est-à-dire sous tension, et une fiche 2 munie d'une broche 3 de contact. A connector according to the invention comprises a base 1 active, that is to say under tension, and a plug 2 provided with a pin 3 of contact.
La figure 1 montre avec arrachement le socle 1 et la fiche 2 du connecteur en position prêts à être accouplés.  Figure 1 shows broken away the base 1 and plug 2 of the connector in position ready to be coupled.
La broche 3 de la fiche 2 est destinée à coopérer après accouplement avec un contact 4 élastique à pression en bout aménagé dans le socle 1 .  The pin 3 of the plug 2 is intended to cooperate after coupling with an end-pressure elastic contact 4 arranged in the base 1.
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 figures 1 , 4 et 5, tandis que le disque de protection du socle est pourvu d'une ouverture de passage 6 de section rectangulaire qui correspond à la section droite précitée de la broche de la fiche.  The pin 3 of the plug has a substantially rectangular cross section as can be seen in particular in Figures 1, 4 and 5, while the protective disc of the base is provided with a passage opening 6 of rectangular section which corresponds to the aforementioned straight section of the pin of the plug.
Par ailleurs dans le mode de réalisation représenté la broche 3 de la fiche est pourvue de deux ergots latéraux 7 (figures 1 , 4 et 5) destinés à coopérer avec des rampes 8 (figure 3) du socle pour un verrouillage après accouplement, du type à baïonnette.  Furthermore, in the embodiment shown, pin 3 of the plug is provided with two lateral pins 7 (FIGS. 1, 4 and 5) intended to cooperate with ramps 8 (FIG. 3) of the base for locking after coupling, of the type with bayonet.
L'ouverture de passage 6 du disque de protection du socle comporte sur ses petits côtés des encoches 9 (figure 2) pour le passage des ergots 7 de la broche 3 de la fiche.  The passage opening 6 of the protective disc of the base has on its short sides notches 9 (Figure 2) for the passage of the lugs 7 of the pin 3 of the plug.
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 figure 1.  The pin 3 of the plug is further surrounded by a cylindrical sleeve 10 into which is introduced the protective disk 5 of the base as shown more particularly in Figure 1.
On peut voir sur les figures 4 et 5 que le manchon cylindrique 10 est en outre muni d'une nervure longitudinale intérieure 1 1.  It can be seen in Figures 4 and 5 that the cylindrical sleeve 10 is further provided with an inner longitudinal rib 1 January.
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 figures 2 et 6A à 6E.  Correspondingly the protective disc 5 of the base is provided at its periphery with an axial notch 12 as shown in Figures 2 and 6A to 6E.
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 figures 4 et 5 pour la fiche et la figure 2 pour le socle, les décalages angulaires sont égaux entre, d'une part, un plan longitudinal médian de la broche 3 de la fiche parallèle à ses grands côtés avec un plan diamétral au manchon 10 de ladite fiche passant par la nervure 1 1 dudit manchon et, d'autre part, un plan longitudinal médian de l'ouverture de passage 6 du disque de protection du socle parallèle aux grands côtés dudit passage avec un plan diamétral du disque de protection passant par l'entaille 12 de celui-ci. As shown in Figures 4 and 5 for the plug and Figure 2 for the base, the angular offsets are equal between, on the one hand, a median longitudinal plane of the pin 3 of the plug parallel to its long sides with a diametrical plane to the sleeve 10 of said plug passing through the rib 1 1 of said sleeve and, secondly, a median longitudinal plane of the passage opening 6 of the protective disk of the base parallel to the long sides of said passage with a diametrical plane of the disk protection passing through the notch 12 thereof.
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.
Dans l'exemple représenté sur les figures 1 à 6A ce décalage est de 30° (voir plus particulièrement les figures 4 et 6A pour respectivement la fiche et le socle).  In the example shown in Figures 1 to 6A this shift is 30 ° (see more particularly Figures 4 and 6A for respectively the plug and the base).
Afin de prévoir un ensemble de connecteurs, par exemple un ensemble de cinq connecteurs dont l'un est destiné à constituer une prise de terre (figures 1 à 6A), un autre le neutre (figure 6E), et les trois autres des connexions de phases (figures 6B à 6D) il suffit de prévoir des décalages angulaires différents pour chaque connecteur comme le montrent bien lesdites figures 6A à 6E.  In order to provide a set of connectors, for example a set of five connectors, one of which is intended to form a ground connection (FIGS. 1 to 6A), another one the neutral (FIG. 6E), and the other three of the connection connections. phases (FIGS. 6B to 6D) it suffices to provide different angular offsets for each connector as shown in FIGS. 6A to 6E.
La figure 6A montre un socle en vue frontale correspondant au socle des figures 1 et 2 avec un décalage angulaire de l'entaille 12 tel que défini ci-avant de 30° tandis que les figures 6B à 6E montrent des socles avec des décalages angulaires de l'entaille 12 de respectivement 60°, 90°, 120° et 150°.  FIG. 6A shows a base in front view corresponding to the base of FIGS. 1 and 2 with an angular offset of the notch 12 as defined above by 30 ° while FIGS. 6B to 6E show pedestals with angular offsets of the notch 12 of respectively 60 °, 90 °, 120 ° and 150 °.
Pour correspondre aux cinq socles schématisés sur les figures 6A à 6E on a bien sûr prévu des fiches conjuguées dont les nervures 1 1 présentent des décalages angulaires correspondants.  To correspond to the five bases shown diagrammatically in FIGS. 6A to 6E, there are of course provided conjugate plugs whose ribs January 1 have corresponding angular offsets.
Pour éviter des déconnexions intempestives, on peut en outre voir sur les dessins que le manchon cylindrique 10 de la fiche est pourvu dans cet exemple d'un piston 13 rétractable élastiquement (voir notamment les figures 1 , 4 et 5).  To avoid inadvertent disconnections, it can further be seen in the drawings that the cylindrical sleeve 10 of the plug is provided in this example with a piston 13 retractable elastically (see in particular Figures 1, 4 and 5).
Ce piston 13 est destiné à venir au contact d'une collerette 14 aménagée autour du socle (figures 1 , 2, 3 et 6A à 6E) au cours de l'accouplement, se rétracter et venir, après rotation de la fiche et accouplement, dans une encoche 15 ménagée dans ladite collerette (figures 3 et 6A à 6E).  This piston 13 is intended to come into contact with a collar 14 arranged around the base (FIGS. 1, 2, 3 and 6A to 6E) during coupling, to retract and come, after rotation of the plug and coupling, in a notch 15 formed in said collar (Figures 3 and 6A to 6E).
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 piston 13 possibly by means of a special tool.
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 opening passage 6 when the plug and the base are separated .
