Description

L'invention concerne un connecteur électrique de puissance triphasé.The invention relates to a three-phase power electrical connector.

On sait que le court-circuit d'une phase au sein du boîtier d'un connecteur de phase triphasé affecte les autres phases, ce qui empêche l'équipement électrique qui est alimenté pour ce connecteur de continuer à fonctionner, même en mode dégradé sur deux phases.It is known that the short-circuit of a phase within the housing of a three-phase phase connector affects the other phases, which prevents the electrical equipment that is powered for this connector from continuing to operate, even in degraded mode on two phases.

Il existe donc un besoin pour un connecteur électrique triphasé dont le fonctionnement est moins altéré par la défaillance de l'une des phases.There is therefore a need for a three-phase electrical connector whose operation is less impaired by the failure of one of the phases.

US-A1-2008/087466 décrit un connecteur triphasé dont les contactes de connection sont couverts d'un manchon isolante en matière élastomère. US-A1-2008 / 087466 describes a three-phase connector whose connection contacts are covered with an insulating sleeve made of elastomeric material.

Il est proposé un connecteur électrique de puissance triphasé, comportant une fiche et une embase, lesquelles comprennent chacune respectivement un boîtier et trois contacts conducteurs électriques logés au moins partiellement à l'intérieur du boîtier et correspondant chacun à une phase électrique du courant électrique transmis par le connecteur, dans lequel chaque contact conducteur électrique est entouré au moins partiellement d'une gaine isolante électriquement.It is proposed a three-phase electrical power connector, comprising a plug and a base, each of which respectively comprises a housing and three electrical conductor contacts housed at least partially inside the housing and each corresponding to an electrical phase of the electric current transmitted by the connector, wherein each electrical conductive contact is at least partially surrounded by an electrically insulating sheath.

Il en résulte qu'une anomalie sur une phase du connecteur électrique, retentit peu sur les deux autres phases du connecteur et que l'équipement électrique peut fonctionner en mode dégradé sur deux phases, par exemple continuer à tourner pour un moteur électrique, et surtout continuer à fonctionner en attendant le dépannage pour un rétablissement à un fonctionnement normal.It follows that an anomaly on a phase of the electrical connector, resounds little on the other two phases of the connector and that the electrical equipment can operate in degraded mode on two phases, for example continue to turn for an electric motor, and especially continue to operate while waiting for troubleshooting for recovery to normal operation.

L'invention trouve une application particulièrement intéressante dans les plates-formes pétrolières marines où la réparation d'un connecteur électrique peut nécessiter beaucoup de temps.The invention finds a particularly interesting application in marine oil platforms where the repair of an electrical connector may require a lot of time.

Les gaines de chaque contact sont agencées de sorte que, lorsque la fiche et l'embase sont connectées, les gaines entourant les contacts d'une même phase forment chacune une chambre fermée isolant électriquement les contacts de cette phase.The sheaths of each contact are arranged so that, when the plug and the base are connected, the sheaths surrounding the contacts of the same phase each form a closed chamber electrically insulating the contacts of this phase.

Ainsi, en position connectée de la fiche et de l'embase, chaque phase est isolée électriquement des autres phases situées à l'intérieur du connecteur, cette isolation étant obtenue par les chambres formées par les gaines.Thus, in the connected position of the plug and the base, each phase is electrically insulated from the other phases located inside the connector, this insulation being obtained by the chambers formed by the sheaths.

Avantageusement, les gaines sont de configuration tubulaire entourant chacun des contacts conducteurs électriques.Advantageously, the sheaths are of tubular configuration surrounding each of the electrical conductive contacts.

La section des gaines est de préférence circulaire et la paroi de chacune des gaines entoure le contact (la partie conductrice électrique) à une distance déterminée, suffisante pour empêcher un arc électrique émis au sein de l'une des phases d'atteindre et perturber les autres phases, par exemple égale à 0,01 à 5 fois le diamètre du contact et de préférence égale à 0,3 à 1 fois le diamètre du contact.The section of the sheaths is preferably circular and the wall of each of the sheaths surrounds the contact (the electrically conductive part) at a determined distance, sufficient to prevent an electric arc emitted within one of the phases from reaching and disturbing the other phases, for example equal to 0.01 to 5 times the diameter of the contact and preferably equal to 0.3 to 1 times the diameter of the contact.

La paroi de chacune des gaines est constituée d'une matière isolante électrique, par exemple une matière plastique diélectrique. L'épaisseur de chaque gaine sera déterminée en fonction de la tension du courant électrique transmis par le connecteur, et sera avantageusement suffisante pour que la paroi ne puisse pas être traversée par un arc électrique..The wall of each of the sheaths is made of an electrical insulating material, for example a dielectric plastic material. The thickness of each sheath will be determined as a function of the voltage of the electrical current transmitted by the connector, and will advantageously be sufficient so that the wall can not be traversed by an electric arc.

De plus, l'épaisseur de chaque gaine peut être déterminée en fonction de la distance de la gaine au contact pour que la paroi ne puisse pas être traversée par un arc électrique.In addition, the thickness of each sheath can be determined according to the distance of the sheath to contact so that the wall can not be traversed by an electric arc.

Ainsi, en fonction de la tension du courant électrique transmis par le connecteur, on peut combiner l'épaisseur de la gaine et la distance de la gaine au contact pour que la paroi ne puisse pas être traversée par un arc électrique.Thus, as a function of the voltage of the electric current transmitted by the connector, it is possible to combine the thickness of the sheath and the distance of the sheath to the contact so that the wall can not be traversed by an electric arc.

De cette façon, un arc électrique émis au sein de l'une des chambres de gaine est empêché de traverser la chambre pour atteindre et perturber les autres phases.In this way, an electric arc emitted within one of the sheath chambers is prevented from crossing the chamber to reach and disturb the other phases.

Avantageusement, chacune des gaines est au moins partiellement revêtue intérieurement et/ou extérieurement d'une couche de blindage électrique, par exemple une couche de métallisation ou une tresse métallique reliée à une masse électrique, ce qui isole toute anomalie électrique de champ électromagnétique sur l'une des phases susceptible d'affecter les autres phases.Advantageously, each of the sheaths is at least partially coated internally and / or externally with an electrical shielding layer, for example a metallization layer or a metal braid connected to an electrical mass, which isolates any electrical anomaly of the electromagnetic field on the screen. one of the phases likely to affect the other phases.

Le connecteur peut être utilisé dans des applications sous-marines et dans ce cas au moins un boîtier de la fiche et/ou de l'embase du connecteur contient de l'huile isolante électrique (huile diélectrique), de préférence à un état de surpression relativement à un milieu environnant, marin notamment (de quelques bars), de manière à empêcher toute entrée d'eau dans le connecteur. Ainsi, le fait de mettre le connecteur en surpression par rapport à l'environnement marin permet d'évacuer de l'huile du boîtier vers l'extérieur (en faible quantité) et d'empêcher la tendance de migration du milieu externe vers l'intérieur au risque de polluer l'huile.The connector can be used in submarine applications and in this case at least one housing of the plug and / or the connector base contains electrical insulating oil (dielectric oil), preferably in a state of overpressure relative to a surrounding environment, marine in particular (of a few bars), so as to prevent any entry of water into the connector. Thus, the fact of putting the connector in overpressure with respect to the marine environment makes it possible to evacuate oil from the housing to the outside (in weak condition). quantity) and to prevent the tendency of migration from the external environment inwards to the risk of polluting the oil.

La gaine d'un contact peut être en plusieurs parties, au moins deux parties qui se chevauchent l'une l'autre.The sheath of a contact may be in several parts, at least two parts overlapping each other.

Les contacts de la fiche seront par exemple des éléments de contact femelles, tandis que les contacts de l'embase seront des éléments de contact mâles, ces éléments mâles et femelles étant conçus pour coopérer et assurer le contact électrique.The contacts of the plug will for example be female contact elements, while the contacts of the base will be male contact elements, these male and female elements being designed to cooperate and ensure the electrical contact.

Les éléments de contact femelles sont avantageusement de type à navette ou à piston, étant montés chacun avec une partie cylindrique avant coulissant dans une partie tubulaire de contact complémentaire, la partie cylindrique avant étant poussée dans la partie tubulaire de contact par l'élément de contact mâle correspondant à la manoeuvre de connection du connecteur.The female contact elements are advantageously of the shuttle or piston type, each being mounted with a cylindrical portion before sliding in a complementary contact tubular part, the front cylindrical part being pushed into the tubular contact part by the contact element. male corresponding to the connection operation of the connector.

Dans ce type de connecteur, la gaine d'un contact mâle ne recouvre pas l'extrémité du contact mâle destinée à venir s'insérer à l'intérieur du contact femelle et la partie d'extrémité de la gaine (côté face de connection) du contact femelle qui assure l'étanchéité avec le milieu extérieur fait suffisamment saillie du contact femelle pour, en position connectée, recouvrir entièrement l'extrémité du contact mâle non couverte par de la gaine.In this type of connector, the sheath of a male contact does not cover the end of the male contact intended to fit inside the female contact and the end portion of the sheath (connection face side). the female contact which seals with the external medium protrudes sufficiently from the female contact to, in the connected position, completely cover the end of the male contact not covered by the sheath.

Les gaines des contacts femelles peuvent être en plusieurs parties, au moins deux parties qui se chevauchent l'une l'autre.The sheaths of the female contacts may be in several parts, at least two parts which overlap each other.

Avantageusement, le connecteur comprend des moyens d'étanchéité pour protéger le connecteur d'un fluide extérieur, par exemple l'eau de mer.Advantageously, the connector comprises sealing means for protecting the connector of an external fluid, for example seawater.

Les moyens d'étanchéité peuvent être constitués par la gaine des câbles conducteurs reliés aux contacts, cette gaine pouvant être revêtue d'une couche de métallisation, laquelle renforce l'étanchéité de la gaine à l'eau de mer, notamment aux hautes pressions sous-marines et protége ainsi le connecteur d'une entrée d'eau entre la gaine isolante et le contact. De plus, la couche de métallisation permet de mieux contrôler le champ électrique émis par le courant en cas de pic de surtension électrique.The sealing means may consist of the sheath of the conductive cables connected to the contacts, this sheath may be coated with a metallization layer, which reinforces the sealing of the sheath with seawater, especially at high pressures under -marines and thus protects the connector of a water inlet between the insulating sheath and the contact. In addition, the metallization layer makes it possible to better control the electric field emitted by the current in the event of an electrical surge surge.

Les moyens d'étanchéité peuvent également comprendre au moins une partie de gaine formant membrane d'essuyage des contacts d'une même phase (par exemple des contacts mâle et femelle) connectés ensemble, apte à essuyer chacun des contacts aux opérations de connection et déconnection du connecteur, en sorte que toute trace de fluide (eau de mer ou air) soit empêchée d'entrer dans le connecteur (entre la gaine et le contact, et/ou dans le boîtier) au risque d'affecter le champ électrique à ce niveau.The sealing means may also comprise at least one wiping membrane sheath portion of the contacts of the same phase (for example male and female contacts). connected together, able to wipe each of the contacts to the connection and disconnection of the connector, so that any trace of fluid (seawater or air) is prevented from entering the connector (between the sheath and the contact, and / or in the case) at the risk of affecting the electric field at this level.

Les éléments de contact 7, 9 sont inscrits dans un même cercle transversal à l'axe (d) du boîtier (figure 2), à 120° l'un de l'autre, en correspondance axiale d'un élément de contact mâle 7 à un élément de contact femelle 9.This connector comprises a base 3 and a complementary plug 5, which is intended to be coupled to the base 3 at the time of connection of the connector. The base 3 comprises three male contact elements 7 and the plug 5 has three female contact elements 9 intended to receive in electrical contact engagement the male contact elements 7. These contact elements 7, 9 of the base and the the plug are housed in a respective housing 11, 13 of the base and the plug of which at least one of the housings 13 contains dielectric oil 15. The contact elements 7, 9 are registered in the same circle transverse to the axis (d) of the housing ( figure 2 ) at 120 ° from each other in axial correspondence of a male contact element 7 to a female contact element 9.

Les trois phases identiques du connecteur sont constituées lorsque les éléments de contact mâle 7 et femelle 9 sont accouplés et transmettent le courant électrique.The three identical phases of the connector are constituted when the male and female contact elements 9 are coupled and transmit the electric current.

Les trois éléments de contact mâle 7 montés dans le boîtier 11 d'embase font saillie au-delà de la face de connection 17 dans une partie 19 de guidage de l'embase (ou partie de manchon) adjacente et coaxiale au boîtier 11 de l'embase.The three male contact elements 7 mounted in the base housing 11 protrude beyond the connecting face 17 in a portion 19 for guiding the base (or sleeve portion) adjacent and coaxial with the housing 11 of the 'base.

Les trois éléments de contact femelle 9 correspondants, logés dans le boîtier 13 de la fiche sont affleurants de la face de connection 35. Ils sont de type à navette ou à piston, étant montés chacun avec une partie cylindrique avant 21 (du côté de la face de connection 35) coulissant dans une partie tubulaire de contact complémentaire 23, cette partie cylindrique avant 21 étant repoussée dans la partie tubulaire de contact 23, à l'intérieur du boîtier 13 par l'élément de contact mâle correspondant 7 à la manoeuvre de connection du connecteur.The three corresponding female contact elements 9 housed in the housing 13 of the plug are flush with the connection face 35. They are of the shuttle or piston type, each being mounted with a cylindrical portion before 21 (on the side of the connecting face 35) sliding in a tubular complementary contact portion 23, this front cylindrical portion 21 being pushed into the tubular contact portion 23, inside the housing 13 by the male contact element corresponding to the maneuver of connector connection.

Les éléments de contact mâle 7 de l'embase 3 comportent chacun une partie conductrice cylindrique interne 25, une tête avant 27 (du côté de la face de connection 17) disposée dans la partie de manchon 19, et une partie conductrice arrière 29 reliée à un câble conducteur (non représenté) du connecteur.The male contact elements 7 of the base 3 each comprise an inner cylindrical conductive portion 25, a front head 27 (on the side of the connection face 17) disposed in the sleeve portion 19, and a rear conductive portion 29 connected to a conductive cable (not shown) of the connector.

La partie cylindrique interne 25 est revêtue d'une gaine isolante électrique 31. Cette gaine 31 ne recoure pas l'extrémité ou la tête 27 du contact mâle destinée à venir s'insérer à l'intérieur du contact femelle (la partie 23).The inner cylindrical portion 25 is coated with an electrical insulating sheath 31. This sheath 31 does not recur the end or the head 27 of the male contact intended to be inserted inside the female contact (the part 23).

Les éléments de contact femelle 9 de la fiche 5 comportent chacun une bande de contact ressort 23a dans la partie conductrice tubulaire de contact 23 correspondante. Cette bande contact ressort 23a est destinée à recevoir en contact interne, à la connection, la tête conductrice avant 27 de l'élément de contact mâle 7. Une partie conductrice cylindrique arrière 33 reliée à la bande de contact ressort 23a, et la partie cylindrique avant 21 ferment la face de connection 35 de la fiche 5 en position déconnectée.The female contact elements 9 of the plug 5 each comprise a spring contact strip 23a in the corresponding tubular conductive contact portion 23. This spring contact strip 23a is intended to receive in internal contact, at the connection, the front conductive head 27 of the male contact element 7. A rear cylindrical conductive portion 33 connected to the contact strip spring 23a, and the cylindrical portion before 21 close the connection face 35 of the plug 5 in the disconnected position.

La partie cylindrique avant 21 est isolante électrique. Elle comprend un corps tubulaire 21a et une partie cylindrique pleine avant 21b dont la face d'extrémité avant 21c est évidée de façon complémentaire de la face avant 27a (en portion de cône) de la tête conductrice avant 27 de l'élément de contact mâle. Une tige 37 pourvue d'un piston 39 à son extrémité arrière est montée coaxialement et solidairement à la partie cylindrique pleine avant 21b. Cette tige 37 s'étend axialement au sein du corps tubulaire 21a de la partie cylindrique isolante avant, faisant saillie du corps tubulaire 21a à son ouverture. Le piston 39 est monté coulissant dans une chambré tubulaire perforée 41 disposée à l'intérieur de la bande de contact ressort 23a, coaxialement à cette dernière. Cette chambre tubulaire 41 est montée solidairement à la bande de contact ressort 23a par son extrémité arrière.The cylindrical front portion 21 is electrically insulating. It comprises a tubular body 21a and a full cylindrical front portion 21b whose front end face 21c is recessed complementary to the front face 27a (in cone portion) of the front conductive head 27 of the male contact element . A rod 37 provided with a piston 39 at its rear end is mounted coaxially and integrally with the solid cylindrical portion before 21b. This rod 37 extends axially within the tubular body 21a of the front insulating cylindrical portion, projecting from the tubular body 21a at its opening. The piston 39 is slidably mounted in a perforated tubular chamber 41 disposed inside the spring contact strip 23a, coaxially with the latter. This tubular chamber 41 is integrally mounted to the spring contact strip 23a at its rear end.

Un ressort hélicoïdal 43 est monté autour de la tige 37 de piston et de la chambre tubulaire 41, en appui par une première extrémité 45 sur le fond du corps tubulaire 21a de la partie cylindrique avant et par une deuxième extrémité 47 opposée à la précédente sur un épaulement d'extrémité 49 de la chambre tubulaire 41. Ce ressort 43 est destiné à rappeler vers l'avant le coulissement de la partie cylindrique avant 21 dans la bande de contact ressort 23a.A helical spring 43 is mounted around the piston rod 37 and the tubular chamber 41, supported by a first end 45 on the bottom of the tubular body 21a of the front cylindrical portion and by a second end 47 opposite the previous one on an end shoulder 49 of the tubular chamber 41. This spring 43 is intended to bias forward sliding of the front cylindrical portion 21 in the spring contact strip 23a.

La bande de contact ressort 23a comporte deux joints lécheurs toriques adjacents 51 montés dans la partie d'alésage de la bande de contact ressort 23a. Ces joints lécheurs 51 sont disposés proches de l'extrémité avant de la bande de contact ressort 23a. Ils sont appliqués sur le corps tubulaire 21a de la partie cylindrique avant 21 et font barrière à la migration vers l'extérieur de l'huile diélectrique 15 contenue dans le boîtier et à l'entrée de fluide environnant dans l'huile.The spring contact strip 23a has two adjacent toroidal seal seals 51 mounted in the bore portion of the spring contact strip 23a. These seals 51 are arranged near the front end of the spring contact strip 23a. They are applied to the tubular body 21a of the front cylindrical portion 21 and are a barrier to the outward migration of the dielectric oil 15 contained in the housing and the surrounding fluid inlet in the oil.

Trois joints annulaires adjacents 53 sont montés sur le boîtier 13 à proximité de l'ouverture 55 de la face de connection 35 correspondante de la fiche, coaxialement à cette ouverture 55. Ces joints 53 forment une partie racleur destinée à être appliquée sur la partie cylindrique isolante électrique avant 21 et sur la tête avant 27 de l'élément de contact mâle au cours de la manoeuvre de connection.Three adjacent annular seals 53 are mounted on the housing 13 near the opening 55 of the corresponding connection face 35 of the plug, coaxially with this opening 55. These seals 53 form a scraper portion intended to be applied to the cylindrical portion electrical insulation before 21 and on the front head 27 of the male contact element during the connection operation.

A l'arrière de cette partie racleur 53 est disposée une gaine formant membrane cylindrique épaisse souple 57, s'étendant jusqu'à l'extrémité de la bande de contact ressort 23a et destinée à s'appliquer en compression sur la partie cylindrique isolante électrique avant 21 et sur la tête avant 27 de l'élément de contact mâle en cours de la manoeuvre de connexion. Cette membrane 57 permet d'essuyer le corps tubulaire 21 et la tête 27 du contact mâle au cours de leur coulissement à la connexion et d'empêcher ainsi toute entrée de fluide (eau de mer) à ce niveau. Cette membrane cylindrique épaisse souple 57 est également isolante électrique.At the rear of this scraper portion 53 is disposed a flexible thick cylindrical membrane sheath 57, extending to the end of the spring contact strip 23a and intended to be applied in compression on the front electrical insulating cylindrical portion 21 and on the front head 27 of the male contact element during the connection operation. This membrane 57 makes it possible to wipe the tubular body 21 and the head 27 of the male contact during their sliding at the connection and thus prevent any entry of fluid (seawater) at this level. This flexible thick cylindrical membrane 57 is also electrically insulating.

Ces joints 51, 53 et membrane 57 forment des moyens d'étanchéité pour protéger le connecteur d'un fluide extérieur.These seals 51, 53 and membrane 57 form sealing means to protect the connector from an external fluid.

La bande de contact ressort 23a et la partie conductrice cylindrique arrière 33 sont en outre enveloppées par une gaine isolante électrique 59. Cette gaine 59 découvre l'extrémité de la partie cylindrique conductrice arrière 33, laquelle est reliée à un câble conducteur électrique de la fiche (non représenté).The contact strip spring 23a and the rear cylindrical conductive portion 33 are further enveloped by an electrical insulating sheath 59. This sheath 59 discovers the end of the rear conductive cylindrical portion 33, which is connected to an electrical conductor cable of the plug (not shown)

Entre cette gaine 59 et la bande de contact ressort 23a est ménagé un espace de jeu régulier (e) et une ligne de fuite 61 de l'huile diélectrique 15 contenue dans cette bande de contact ressort 23a. L'huile diélectrique 15 à la connection, en raison du coulissement du corps tubulaire 21 dans la bande de contact ressort 23a et de la diminution de volume correspondante de l'espace dans ce corps tubulaire 21 et la bande de contact ressort 23a, est véhiculée au travers de la bande de contact ressort 23a (fendue) et par la ligne de fuite 61 jusqu'à une chambre cylindrique 63 de compensation de volume formée coaxialement dans le boîtier. Cette chambre de compensation 63 comprend un piston 65 monté coulissant et rappelé par ressort 67 dans l'alésage de la chambre 63. Le piston 65 est déplacé dans cette chambre 63 par la pression de l'huile diélectrique 15 véhiculée depuis le corps tubulaire 21 et la bande de contact ressort 23a.Between this sheath 59 and the spring contact strip 23a is formed a regular clearance space (e) and a leakage line 61 of the dielectric oil 15 contained in this spring contact strip 23a. The dielectric oil 15 at the connection, due to the sliding of the tubular body 21 in the spring contact strip 23a and the corresponding volume decrease of the space in this tubular body 21 and the spring contact strip 23a, is conveyed through the spring contact strip 23a (slotted) and through the escape line 61 to a cylindrical volume-compensating chamber 63 formed coaxially in the housing. This compensation chamber 63 comprises a piston 65 slidably mounted and spring-loaded 67 in the bore of the chamber 63. The piston 65 is moved in this chamber 63 by the pressure of the dielectric oil 15 conveyed from the tubular body 21 and the contact strip spring 23a.

L'huile 15 du boîtier de connecteur est en légère surpression (de quelques bars) relativement au milieu environnant extérieur (eau de mer).The oil 15 of the connector housing is slightly overpressured (a few bars) relative to the surrounding environment (seawater).

En outre, la gaine isolante électrique 59 et la gaine 57 de l'élément de contact femelle 9, qui se recouvrent l'une l'autre, isolent électriquement la bande de contact ressort 23a, la partie cylindrique avant 21 et la partie cylindrique conductrice arrière 33.In addition, the electrical insulating sheath 59 and the sheath 57 of the female contact element 9, which overlap one another, electrically isolate the spring contact strip 23a, the front cylindrical portion 21 and the conductive cylindrical portion. rear 33.

A la connexion (figure 5), les gaines isolantes électriques 31, 57 et 59 de l'élément de contact mâle 7 et de l'élément de contact femelle 9 se chevauchent, ce qui forme pour la phase de courant une chambre continue isolante électrique.At the connection ( figure 5 ), the electrical insulating sheaths 31, 57 and 59 of the male contact element 7 and the female contact element 9 overlap, which forms an electric insulating continuous chamber for the current phase.

De plus, une couche d'argenture 69 (métallisation) recouvre partiellement: les gaines isolantes 31, 59, ce qui permet de constituer par exemple une ligne de potentiel de masse (reliée à la masse électrique) pour la reprise des pics de tension à la surface de la chambre et d'assurer la régularisation de cette tension.In addition, a silvering layer 69 (metallization) partially overlaps: the insulating sheaths 31, 59, which makes it possible, for example, to constitute a ground potential line (connected to the electrical earth) for the resumption of voltage peaks at the surface of the chamber and to ensure the regularization of this tension.

Le fonctionnement du connecteur 1 est à présent décrit.The operation of the connector 1 is now described.

La fiche 5 est introduite dans l'ouverture évasée 19a de la partie manchon 19 de l'embase, convenablement indexée angulairement par rapport à cette dernière, par exemple par un système clavette 71 et rainure correspondante 73 puis est guidée axialement par glissement dans la partie manchon 19 (figure 3) jusqu'à ce que l'extrémité 27a des têtes avant 27 de chacun des éléments de contact mâle s'applique contre l'extrémité évidée 21c de la partie cylindrique avant 21 de chacun des éléments de contact femelle. Ce faisant, le fluide environnant contenu dans la partie manchon 19 est évacué de celle-ci par des trous ou fentes adéquats 19b prévus dans la paroi de cette partie manchon.The plug 5 is inserted into the flared opening 19a of the sleeve portion 19 of the base, suitably indexed angularly with respect to the latter, for example by a key system 71 and corresponding groove 73 and is guided axially by sliding in the part sleeve 19 ( figure 3 ) until the end 27a of the front heads 27 of each of the male contact members is applied against the recessed end 21c of the front cylindrical portion 21 of each of the female contact elements. In doing so, the surrounding fluid contained in the sleeve portion 19 is removed therefrom by suitable holes or slots 19b provided in the wall of this sleeve portion.

La partie cylindrique isolante électrique avant 21 de chacun des éléments de contact femelle 9 est alors translatée vers l'arrière (figure 4) sous la poussée des éléments de contact mâle correspondants 7. La partie racleur formée par les trois joints annulaires 53 vient essuyer la tête 27 de l'élément de contact mâle, tandis que les deux joints lécheurs 51 sont appliqués sur la périphérie du corps tubulaire 21a de la partie cylindrique isolante avant.The front electrical insulating cylindrical portion 21 of each of the female contact elements 9 is then translated rearwardly ( figure 4 ) under the thrust of the corresponding male contact elements 7. The scraper part formed by the three annular seals 53 wipes the head 27 of the male contact element, while the two seals 51 are applied on the periphery of the tubular body 21a of the front insulating cylindrical part.

L'huile diélectrique 15 contenue dans le corps tubulaire et la bande de contact ressort 23a est véhiculée au travers de la bande de contact ressort 23a, par la ligne de fuite 61 et par un chemin 61' (schématisé en trait interrompu) jusqu'à la chambre cylindrique de compensation de volume 63 associée à chacun des éléments de contact femelle 9.The dielectric oil 15 contained in the tubular body and the spring contact strip 23a is conveyed through the spring contact strip 23a, by the creepage 61 and by a path 61 '(schematized in broken line) to the cylindrical volume compensation chamber 63 associated with each of the female contact elements 9.

En fin de connection, les faces de connection avant 35, 17 de la fiche et de l'embase viennent en contact mutuel et chacune des têtes de contact 27 des éléments de contact mâle s'applique par sa périphérie contre l'alésage de la bande de contact ressort 23a de l'élément de contact femelle (figure 5). La connexion est alors verrouillée en position par un système de verrouillage adéquat du connecteur, par exemple par un module de maintien adjoint (non représenté). La ligne de potentiel 75 du courant de phase transmis par le connecteur est représentée selon un trait fort en périphérie de la partie conductrice électrique des éléments de contact 7, 9 accouplés et de même la ligne de masse 77 en périphérie de la couche isolante électrique 31, 57, 59 de la phase. Naturellement, ces lignes de potentiel 75, 77 s'étendent en continuité dans les câbles conducteurs attenants de la fiche et de l'embase du connecteur.At the end of the connection, the front connecting faces 35, 17 of the plug and the base come into mutual contact and each of the contact heads 27 of the male contact elements is applied by its periphery against the bore of the spring contact strip 23a of the female contact element ( figure 5 ). The connection is then locked in position by a suitable locking system of the connector, for example by an assistant holding module (not shown). The potential line 75 of the phase current transmitted by the connector is represented along a strong line at the periphery of the electrical conductive part of the contact elements 7, 9 coupled and likewise the ground line 77 at the periphery of the electrical insulating layer 31 , 57, 59 of the phase. Naturally, these potential lines 75, 77 extend in continuity in the adjacent conductive cables of the plug and the connector base.

La déconnection de la fiche par rapport à l'embase est obtenue par une manoeuvre inverse à la précédente, les éléments fonctionnant de façon inverse à la connection.The disconnection of the plug relative to the base is obtained by a reverse maneuver to the previous one, the elements operating in reverse to the connection.
