Description

La présente invention concerne un connecteur électrique de puissance de type monopolaire avec continuité de masse pour la protection aux influences électromagnétiques et en particulier un connecteur électrique conforme au préambule de la revendication 1.The present invention relates to an electrical connector of monopolar type with earth continuity for protection against electromagnetic influences and in particular an electrical connector in accordance with the preamble of claim 1.

L'invention concerne en particulier un connecteur électrique de puissance, étanche et blindé, apte à permettre le raccordement de câbles électriques légers, de type aluminium, pour l'utilisation sur les matériels militaires aéroportés. Sur ces matériels, en effet, le blindage aux influences électromagnétiques est impératif.The invention relates in particular to an electrical power connector, sealed and shielded, capable of allowing the connection of light electrical cables, of aluminum type, for use on airborne military equipment. On these materials, in fact, shielding from electromagnetic influences is imperative.

On connaît par le document DE-B-1 946 158 un connecteur électrique de type précité et dont le contact électrique est réalisé avec enveloppement par des éléments isolateurs complémentaires et qui est raccordé par sa partie arrière au câble par l'intermédiaire de sa gaine. Un tel connecteur n'est pas adapté aux applications militaires précitées.Document DE-B-1 946 158 discloses an electrical connector of the aforementioned type and the electrical contact of which is made with envelopment by complementary insulating elements and which is connected by its rear part to the cable by means of its sheath. Such a connector is not suitable for the aforementioned military applications.

Ce but est atteint par un connecteur électrique conforme à l'enseignement de la revendication 1.This object is achieved by an electrical connector in accordance with the teaching of claim 1.

Des dispositions constructives avantageuses sont décrites dans les revendications dépendantes.Advantageous structural arrangements are described in the dependent claims.

En d'autres termes, cette disposition selon la revendication 1 garantit le maintien du positionnement concentrique du contact principal relativement à la partie externe de contact de masse, ce qui est essentiel pour l'obtention de la protection aux influences électromagnétiques. Elle assure par ailleurs le positionnement correct des éléments de contact pour leur engagement. Enfin, du fait de l'étanchéité obtenue sur le raccordement des câbles et sur la connexion elle-même, elle autorise l'utilisation de contacts dits "bi-métal" avec câble léger pour utilisation militaire aéroportée, notamment à âme en aluminium, les protégeant des phénomènes de pollution ou oxydation (formation d'alumine) dûs au renouvellement de l'air qui se trouve à l'intérieur du connecteur ainsi enbroché.In other words, this arrangement according to claim 1 guarantees that the concentric positioning of the main contact is maintained relative to the external mass contact part, which is essential for obtaining protection from electromagnetic influences. It also ensures the correct positioning of the contact elements for their engagement. Finally, because of the seal obtained on the cable connection and on the connection itself, it allows the use of so-called "bi-metal" contacts with light cable for airborne military use, in particular with an aluminum core, protecting from pollution or oxidation phenomena (formation of alumina) due to the renewal of the air which is inside the connector thus plugged in.

L'invention est illustrée ci-après à l'aide d'exemples de réalisation décrits à titre non limitatif et en référence aux dessins annexés sur lesquels :

  • La figure 1 est une vue en coupe médiane partielle d'une fiche droite (partie mâle) raccordée à un câble de cuivre d'un connecteur selon l'invention ;
  • La figure 2 est une coupe analogue de la partie femelle ou embase du connecteur recevant la fiche selon la figure 1 ;
  • Les figures 3 et 4 sont des vues analogues à la figure 1, respectivement, d'une fiche droite et d'une fiche coudée raccordées à un câble en aluminium de connecteurs dits "bi-métal" selon l'invention.
The invention is illustrated below using examples of embodiment described without limitation and with reference to the accompanying drawings in which:
  • Figure 1 is a partial middle sectional view of a straight plug (male part) connected to a copper cable of a connector according to the invention;
  • Figure 2 is a similar section of the female part or base of the connector receiving the plug according to Figure 1;
  • Figures 3 and 4 are views similar to Figure 1, respectively, of a straight plug and a bent plug connected to an aluminum cable of connectors called "bi-metal" according to the invention.

La fiche représentée en figure 1 correspond à la partie mâle du connecteur, la partie femelle symétrique ou embase portant l'alvéole 1 recevant la broche de contact principal 3 étant représentée en figure 2. Cette fiche comporte un élément de contact principal 3, comme précité, une partie formant contact de masse 5, une partie formant raccordement 7 du câble électrique embroché 9, une partie support 11 du contact principal et une partie externe 13 formant corps du connecteur.The plug represented in FIG. 1 corresponds to the male part of the connector, the symmetrical female part or base carrying the socket 1 receiving the main contact pin 3 being represented in FIG. 2. This plug comprises a main contact element 3, as mentioned above. , a part forming a ground contact 5, a part forming a connection 7 of the plugged-in electric cable 9, a support part 11 of the main contact and an external part 13 forming the body of the connector.

Cette dernière partie en métal léger, à laquelle sont fixés les éléments précités, est formée de parties jointes l'une à l'autre, respectivement, une partie avant 13a et une partie arrière 13b. Elle assure la continuité électrique de masse du connecteur. Elle est en effet reliée par sa partie extrême arrière ou embout 15 à la tresse de masse du câble qui y est fixée sur toute sa périphérie (360° d'angle) de façon classique par une bague de serrage et à l'avant elle porte la partie de contact de masse 5 cylindrique classique destinée à coopérer en engagement de contact avec la partie complémentaire correspondante 5′ de la partie femelle du connecteur. L'étanchéité de l'engagement entre ces parties de contact de masse est assurée par un joint élastique 17 en forme de jonc, logé dans une rainure adéquate de l'une des parties.This last part in light metal, to which the aforementioned elements are fixed, is formed of parts joined to each other, respectively, a front part 13a and a rear part 13b. It ensures the electrical ground continuity of the connector. It is in fact connected by its rear end part or end piece 15 to the ground braid of the cable which is fixed there over its entire periphery (360 ° angle) in a conventional manner by a clamping ring and at the front it carries the conventional cylindrical mass contact part 5 intended to cooperate in contact engagement with the corresponding complementary part 5 ′ of the female part of the connector. The engagement between these earth contact parts is sealed by an elastic ring 17 in the form of a rod, housed in a suitable groove in one of the parts.

La partie de contact principal est une broche cylindrique mâle pleine classique disposée concentriquement à la partie externe environnante de contact de masse 5. Son diamètre est variable en fonction de la puissance à transmettre. Cette partie qui coopère, comme précité, avec l'alvéole correspondante 1 de la partie femelle du connecteur est en alliage cuivreux protégé par traitement de surface contre l'oxydation. Elle est solidaire d'une partie support 11 formée dans le même matériau. Cette dernière partie est essentiellement cylindrique d'axe celui du connecteur, comportant un fût interne 19 logeant la partie dénudée en contact de l'extrémité du câble raccordé 9 et une surface externe 21 portée en liaison souple, étanche et isolante avec la partie de corps externe du connecteur. Cette surface externe comporte une gorge 23 formée vers l'avant avec un flan droit avant 25 et un flan incliné arrière 27. Cette gorge reçoit une bague déformable (semi-rigide) 29 de forme trapézoïdale, laquelle est interposée dans un espace prévu entre deux pièces isolateurs rigides, l'une en forme de marche d'escalier 31 à l'avant et l'autre de section élargie 33 à l'arrière. La pièce isolateur avant 31 est montée en retenue sur un épaulement 35 formé sur la partie de corps 13a et vient recouvrir la face avant de la pièce support 11 du contact.The main contact part is a conventional solid male cylindrical pin arranged concentrically with the surrounding external mass contact part 5. Its diameter is variable as a function of the power to be transmitted. This part which cooperates, as mentioned above, with the corresponding socket 1 of the female part of the connector is made of copper alloy protected by surface treatment against oxidation. It is integral with a support part 11 formed from the same material. This last part is essentially cylindrical with an axis of that of the connector, comprising an internal barrel 19 housing the stripped part in contact with the end of the connected cable 9 and an external surface 21 carried in flexible, sealed and insulating connection with the body part. connector. This external surface has a groove 23 formed towards the front with a straight front blank 25 and a rear inclined blank 27. This groove receives a deformable (semi-rigid) ring 29 of trapezoidal shape, which is interposed in a space provided between two rigid insulating parts, one in the form of a stair step 31 at the front and the other of enlarged section 33 at the rear. The front insulating part 31 is mounted as a retainer on a shoulder 35 formed on the body part 13a and covers the front face of the support part 11 of the contact.

La pièce isolateur arrière 33 comporte un épaulement arrière 37 par lequel elle reçoit une bague de serrage 39 vissée avec d'arrêt 41 sur la surface interne de la partie de corps. Cette bague de serrage permet d'appliquer en pression les pièces isolateurs l'une contre l'autre, d'une part, et sur la surface interne correspondante de la partie de corps, d'autre part, grâce à la compression de la bague déformable interne 29 emprisonnée appliquée sur la partie de support du contact. La partie de support de contact 11 est ainsi solidarisée à la partie de corps 13a et la bague souple 29 rattrape le jeu d'ajustement des pièces isolateurs 31 et 33, assurant un positionnement concentrique, souple et étanche du contact relativement à la partie de corps.The rear insulating part 33 comprises a rear shoulder 37 by which it receives a clamping ring 39 screwed with stop 41 on the internal surface of the body part. This clamping ring allows the pressure insulating parts to be applied against each other, on the one hand, and on the corresponding internal surface of the body part, on the other hand, thanks to the compression of the ring. internal deformable 29 trapped applied to the contact support part. The contact support part 11 is thus secured to the body part 13a and the flexible ring 29 catches up with the adjustment clearance of the insulating parts 31 and 33, ensuring a concentric, flexible and sealed positioning of the contact relative to the body part. .

Pour la partie femelle ou embase du connecteur (Figure 2), le positionnement de l'alvéole 1 sur la partie de corps est identique, excepté que l'isolateur de retenue avant 31′ s'étend sur la longueur de l'alvéole.For the female part or base of the connector (Figure 2), the positioning of the cell 1 on the body part is identical, except that the front retaining insulator 31 ′ extends over the length of the cell.

La partie de raccordement 7 du câble pour la fiche est formée à l'arrière du connecteur, sur la partie arrière 13b du corps, laquelle est vissée par une bague de serrage médiane 43 sur la partie avant 13a portant le contact principal et le contact de masse. La bague de serrage 43 est en prise de vissage sur la partie avant 13a,étant retenue sur la partie arrière 13b par une bague d'arrêt 45. Au serrage, ces parties s'appliquent l'une sur l'autre en pression et avec étanchéité sur un joint d'interposition 47.The connection part 7 of the cable for the plug is formed at the rear of the connector, on the rear part 13b of the body, which is screwed by a middle clamping ring 43 on the front part 13a carrying the main contact and the contact of mass. The clamping ring 43 is in screw connection on the front part 13a, being retained on the rear part 13b by a stop ring 45. When tightening, these parts are applied to one another under pressure and with sealing on an interposing joint 47.

Cette partie arrière enferme une bague cylindrique 49 isolante, souple et de section élargie, s'étendant autour de la gaine du câble enfilé, depuis l'embout terminal 15 jusque sensiblement, à un léger jeu près, à l'extrémité externe de la pièce isolateur arrière 33. Au serrage de la bague 43, cette bague 49 se comprime dans son logement avec étanchéité autour du câble électrique et de la surface interne de la partie arrière 13b.This rear part encloses a cylindrical insulating ring 49, flexible and of enlarged section, extending around the sheath of the threaded cable, from the end piece 15 until substantially, with a slight clearance, at the external end of the part. rear insulator 33. When the ring 43 is tightened, this ring 49 compresses in its housing with sealing around the electric cable and the internal surface of the rear part 13b.

Le raccordement du câble est obtenu de façon aisée, par enfilage de l'extrémité dénudée du câble, bague 43 desserrée, jusque dans le fût 19 du contact, par sertissage classique de cette partie dénudée (sertissage hexagonal par pièce adaptée) puis par serrage de la bague 43 de jonction des parties de corps 13a et 13b. Le câble est alors raccordé, solidaire du contact et de la partie arrière du connecteur, étant parfaitement positionné relativement au corps, isolé et serré sur ce dernier.The connection of the cable is obtained easily, by threading the stripped end of the cable, loose ring 43, into the barrel 19 of the contact, by conventional crimping of this stripped part (hexagonal crimping by suitable part) then by tightening of the ring 43 for joining the body parts 13a and 13b. The cable is then connected, secured to the contact and to the rear part of the connector, being perfectly positioned relative to the body, insulated and tightened on the latter.

Ainsi conçu, le connecteur dispose d'une étanchéité à l'air et aux fluides complète, c'est-à-dire au niveau du raccordement du câble, au niveau du connecteur lui-même (entre ses pièces avant et arrière), au niveau de la connexion (entre les contacts de masse de la fiche et de l'embase complémentaire) et enfin au niveau du contact principal (broche et alvéole interne) et le câble lui-même (l'âme dénudée du câble sertie sur le fût de la partie support du contact).Thus designed, the connector has a complete air and fluid tightness, that is to say at the level of the cable connection, at the level of the connector itself (between its front and rear parts), at level of the connection (between the ground contacts of the plug and the additional base) and finally at the level of the main contact (pin and internal cell) and the cable itself (the stripped core of the cable crimped on the barrel of the contact support part).

On notera que ce connecteur peut comporter l'option dite de "rackabilité", à savoir que le branchement ou le débranchement du connecteur peuvent être assurés par manoeuvre d'un tiroir (non représenté) monté coulissant dans une armoire où la partie mobile du connecteur est intégrée sur le fond du tiroir et la partie fixe est implantée par exemple sur le châssis du fond de l'armoire.It will be noted that this connector may include the so-called "rackability" option, namely that the connection or disconnection of the connector can be ensured by operating a drawer (not shown) slidingly mounted in a cabinet where the movable part of the connector is integrated on the bottom of the drawer and the fixed part is installed for example on the chassis of the bottom of the cabinet.

Les manoeuvres se font alors par l'extraction ou la mise en place du tiroir, lequel permet de brancher ou débrancher simultanément plusieurs connecteurs rassemblés. Le tiroir est en principe monté sur rails ou glissières dont la précision de guidage est très nettement insuffisante pour assurer l'alignement correct d'un ou des connecteurs de puissance du tiroir.The operations are then carried out by extracting or installing the drawer, which makes it possible to connect or disconnect several assembled connectors simultaneously. The drawer is in principle mounted on rails or slides whose guiding precision is very clearly insufficient to ensure the correct alignment of one or more power connectors of the drawer.

C'est donc au niveau de chaque connecteur que sont réalisés les rattrapages nécessaires sur les axes X-Y-Z par un montage flottant sur ressort de compensation 50 en spirale placé sur l'un des demi-connecteurs, l'autre étant fixé solidement. La fiche est montée sur le tiroir selon une implantation perpendiculaire à la paroi. Un jeu prévu entre le corps de fiche et son implantation dans la paroi permet un déplacement de l'axe de la fiche dans les axes X et Y (plan de paroi).It is therefore at each connector that the necessary catches are made on the XYZ axes by a floating assembly on a compensating spring 50 in a spiral placed on one of the half-connectors, the other being firmly fixed. The plug is mounted on the drawer in an arrangement perpendicular to the wall. A planned game between the plug body and its implantation in the wall allows movement of the plug axis in the X and Y axes (wall plane).

Lors de la connexion, la fiche se trouve automatiquement recentrée par rapport à l'embase par l'intermédiaire des chanfreins d'extrémités des contacts 5,5′ des parties fixe et mobile. La fiche va pénétrer dans le corps de l'embase, en réalisant la concentricité nécessaire pour le contact électrique. La progression du tiroir assurera par sa course prévue, l'embrochage correct du contact mâle dans l'alvéole. Lorsque le tiroir atteint la position finale, le ressort de compensation se comprimera plus ou moins pour compenser les tolérances de course des tiroirs. (axe Z). Le maintien de la position embrochée est assurée par le verrouillage du tiroir sur son châssis porteur.During connection, the plug is automatically centered with respect to the base via the chamfers of the ends of the contacts 5.5 ′ of the fixed and mobile parts. The plug will enter the body of the base, achieving the necessary concentricity for electrical contact. The progression of the drawer will ensure by its planned stroke, the correct insertion of the male contact in the socket. When the drawer reaches the final position, the compensation spring will compress more or less to compensate for the drawers' travel tolerances. (Z axis). Maintaining the plugged-in position is ensured by locking the drawer on its carrying frame.

Comme indiqué précédemment, le connecteur selon l'invention trouve une pleine validation pour les raccordements de câbles électriques en aluminium qui sont très sujets à l'oxydation. Un tel connecteur dit "bi-métal" est représenté en fiche droite à la figure 3 et en fiche coudée à la figure 4, l'embase restant par exemple celle de la figure 2.As indicated above, the connector according to the invention finds full validation for the connections of electrical aluminum cables which are very subject to oxidation. Such a so-called "bi-metal" connector is shown in straight plug in FIG. 3 and in bent plug in FIG. 4, the base remaining for example that of FIG. 2.

La structure du connecteur est très voisine de celle du connecteur de la figure 1. Le seul changement concerne la partie de raccordement 7 qui consiste en un fût cylindrique interne 19′, en aluminium nickelé (prévenant l'oxydation) soudé par striction dans l'axe du connecteur à la partie de support 11′ en alliage cuivreux du contact principal. Au niveau plus externe, la bague 49′ souple emprisonnée dans la partie arrière du connecteur permet lors du serrage de la bague de jonction 43 de parfaitement positionner en concentricité le câble et le corps 13 formant continuité de masse, de même qu'elle assure une étanchéité périphérique externe près de l'embout 15. Au niveau interne, celle ci est assurée par un jonc d'étanchéité interne 51 logé dans une rainure complémentaire du fut, l'extrémité dénudée du câble étant sertie comme précédemment. Le système d'étanchéité ainsi conçu empêche tout renouvellement d'air au sein du connecteur ainsi formé qui conduirait assez rapidement à sa détérioration par formation d'alumine (oxyde très mauvais conducteur).The structure of the connector is very similar to that of the connector in Figure 1. The only change concerns the connection part 7 which consists of an internal cylindrical barrel 19 ′, made of nickel-plated aluminum (preventing oxidation) welded by necking in the axis of the connector to the support part 11 ′ of copper alloy of the main contact. At the more external level, the flexible ring 49 ′ trapped in the rear part of the connector makes it possible, when tightening the junction ring 43, to perfectly position the cable and the body 13 concentrically forming continuity of mass, just as it ensures a external peripheral sealing near the end piece 15. Internally, this is ensured by an internal sealing ring 51 housed in a groove complementary to the barrel, the stripped end of the cable being crimped as before. The sealing system thus designed prevents any renewal of air within the connector thus formed which would lead fairly quickly to its deterioration by the formation of alumina (very bad conductive oxide).

Le connecteur de la figure 4 est identique au précédent excepté la partie coudée 13c dont le volume plus conséquent est calculé pour le passage en angle de la partie conductrice centrale 53 solidaire du contact principal.The connector of FIG. 4 is identical to the previous one except for the angled part 13c, the larger volume of which is calculated for the angle passage of the central conductive part 53 secured to the main contact.

Claims (4)

  1. An electrical power connector of single-pole type in which the main contact of one of the parts, the male part, is a solid male pin (3) co-operating with the corresponding elastic socket (1) of the complementary part, the female part, and comprising an electrical earth continuity characteristic for protection in relation to electromagnetic influences, which is afforded in conventional manner by electrical connection of the earth braid of the electrical cable (9) connected to the external metallic body part of the connector and by an external earth contact (5, 5′), between said male and female parts, characterised in that in order to provide for sealing and insulating assembly of the connector, relative to the electrical contact and to the connecting cable, said main contact (1, 3) and the connection of the cable on its rear part are mounted in flexible connecting relationship on said connector body (13) with centering on same, by means of two rings of synthetic material which are respectively interposed under pressure, one (29) between the support for the main contact (11, 11′) and the adjacent insulating portions (31, 31′, 33), and the other (49, 49′) between the cable (9) and the rear body part of the connector, said ring (29) being accommodated in a groove (23) formed at the front of the support portion for the main contact (11, 11′), and in a suitable internal space provided between the front insulating portion (31, 31′) and the rear insulating portion (33), the insulating portion (31, 31′) being shaped to hold the support portion towards the front and the rear insulating portion (33) clamped against said front insulating portion by means of an internal ring (39) engaged (screwed) on the body of the connector.
  2. An electrical power connector according to claim 1 characterised in that the main contact (1, 3) and the core of the cable (9), being of essentially circular section, are fixed concentrically to the circular external body part (13) of the connector.
  3. An electrical power connector according to claim 1 or claim 2 characterised in that said ring (49) is of cylindrical shape of enlarged section, extending around the sheath of the cable or its crimping shank portion (19′) in the case of a cable of aluminium, from the terminal portion (15) substantially, except for play, to the outside end of the rear insulating portion (33), said ring being compressed in its housing upon connection of the cable.
  4. An electrical power connector according to one of the preceding claims characterised in that it is mounted in a manner referred to as rackable on an operating sliding drawer by means of a spring (50) for compensation of play in the X-Y direction (perpendicularly to its axis) and in the Z direction (on its axis).
