Description

L'invention concerne les borniers de puissance du type à broches.The invention relates to power terminals of the pin type.

Les connecteurs de puissance sont utilisés dans de nombreux domaines pour réaliser des connexions électriques entre deux éléments qui sont, d'une part, plusieurs sources d'alimentation électrique et, d'autre part, un circuit de distribution de la puissance électrique à différents organes d'un équipement électrique. Les caractéristiques de ces connecteurs dépendent bien entendu de la puissance électrique qu'ils doivent être capables de transmettre sans se détériorer ainsi que des conditions de l'environnement. C'est ainsi qu'en aéronautique, les puissances électriques sont transmises sous une relativement faible tension et il en résulte donc des intensités de courant très importantes qui échauffent d'une façon générale les conducteurs électriques mais plus particulièrement les contacts du connecteur, notamment lorsque la liaison électrique entre lesdits contacts n'est pas parfaite.Power connectors are used in many fields to make electrical connections between two elements which are, on the one hand, several sources of electrical power and, on the other hand, a circuit for distributing electrical power to different organs electrical equipment. The characteristics of these connectors obviously depend on the electrical power which they must be able to transmit without deteriorating as well as on environmental conditions. Thus in aeronautics, the electrical powers are transmitted at a relatively low voltage and this therefore results in very large current intensities which generally heat the electrical conductors but more particularly the connector contacts, especially when the electrical connection between said contacts is not perfect.

Cette mauvaise liaison électrique au niveau des contacts peut provenir de divers facteurs tels que l'absence d'homogénéité des surfaces en regard, la détérioration du contact électrique entre les surfaces en regard due aux modifications de l'environnement : humidité, vibrations et le vieillissement rapide des éléments mécaniques dû aux vibrations et aux échauffements locaux fréquents.This poor electrical connection at the contact level can result from various factors such as the lack of homogeneity of the facing surfaces, the deterioration of the electrical contact between the facing surfaces due to changes in the environment: humidity, vibrations and aging. mechanical components due to frequent local vibrations and overheating.

Par suite de ces problèmes, les connecteurs de puissance à broches sont peu utilisés en aéronautique sauf lorsqu'il s'agit d'effectuer des connexions électriques intermittentes et de faible durée. Dans le cas de connexions quasi-permanentes, les constructeurs aéronautiques évitent d'utiliser des connecteurs à broches et, s'ils les acceptent, ils imposent des contraintes mécaniques qui rendent difficile leur montage et démontage, ce qui enlève tout intérêt à un tel type de connexion.As a result of these problems, power pin connectors are little used in aeronautics except when it comes to making intermittent and short duration electrical connections. In the case of quasi-permanent connections, aircraft manufacturers avoid using pin connectors and, if they accept them, they impose mechanical stresses which make their assembly and disassembly difficult, which removes any interest in such a type of connection.

Afin de faciliter la maintenance et l'entretien de certains appareils de bord et leur remplacement éventuel, les connexions électriques entre ces appareils et les circuits électriques fixes de bord doivent être facilement démontables. Or ceci est habituellement obtenu par un dispositif à broches ou bornier dont la partie femelle est fixe tandis que la partie mâle est disposée sur l'appareil à enlever, dispositif à broches qui présente les inconvénients signalés ci-dessus.In order to facilitate the maintenance and upkeep of certain on-board devices and their possible replacement, the electrical connections between these devices and the fixed on-board electrical circuits must be easily removable. However, this is usually obtained by a pin device or terminal block, the female part of which is fixed while the male part is arranged on the device to be removed, a pin device which has the drawbacks indicated above.

Un but de la présente invention est donc de réaliser un bornier de puissance à broches, qui permet d'obtenir et de maintenir un excellent contact électrique entre les parties mâle et femelle même dans le cas où il est soumis à des vibrations de manière continue.An object of the present invention is therefore to produce a power terminal block with pins, which makes it possible to obtain and maintain excellent electrical contact between the male and female parts even in the case where it is subjected to vibrations continuously.

Un autre but de la présente invention est également de réaliser un bornier de puissance à broches, dont les deux parties mâle et femelle peuvent être facilement et rapidement assemblées et démontées.Another object of the present invention is also to provide a power terminal block to pins, of which the two male and female parts can be easily and quickly assembled and disassembled.

Un autre but de la présente invention est de réaliser un bornier de puissance à broches, dont les douilles et les broches peuvent être facilement et rapidement assemblées et démontées sur leur support respectif.Another object of the present invention is to provide a power terminal block with pins, the sockets and pins of which can be easily and quickly assembled and disassembled on their respective support.

L'invention se rapporte à un bornier de puissance du type à broches comprenant une partie femelle et une partie mâle prévues pour s'assembler l'une dans l'autre, caractérisé en ce que la partie femelle comporte une embase qui présente, du côté mâle, une surface plate et, de l'autre côté, des alvéoles pour accommoder chacune l'extrémité d'un conducteur et chaque alvéole étant percée d'un trou à travers l'embase dans lequel est mis en place et maintenue de maniére flottante une douille femelle, en ce que la partie mâle comporte une plaque qui présente, du côté femelle, une surface plate et qui est percée de trous en nombre égal à celui des douilles, une broche mâle étant montée dans chaque trou, chaque trou de la plaque comportant, côté femelle, un premier alésage qui reçoit un joint élastique ayant une épaisseur plus grande que la profondeur de l'alésage, de manière que lors de l'assemblage des parties mâle et femelle le joint vient s'appuyer sur la douille pour la bloquer dans son logement.The invention relates to a power terminal block of the pin type comprising a female part and a male part intended to be assembled one inside the other, characterized in that the female part comprises a base which has, on the side male, a flat surface and, on the other side, cells to each accommodate the end of a conductor and each cell being pierced with a hole through the base in which is placed and held in a floating manner a female socket, in that the male part comprises a plate which has, on the female side, a flat surface and which is pierced with holes in number equal to that of the sockets, a male pin being mounted in each hole, each hole of the plate comprising, on the female side, a first bore which receives an elastic seal having a thickness greater than the depth of the bore, so that during the assembly of the male and female parts the seal comes to rest on the has socket to lock it in its housing.

Pour le guidage des parties mâle et femelle lors de leur assemblage, il est avantageusement prévu des pions de centrage sur la partie mâle et des canons de centrage sur la partie femelle qui sont portés par des oreilles latérales de la plaque de support de la partie mâle et de l'embase de la partie femelle.Advantageously, pins for guiding the male and female parts during their assembly are provided. centering on the male part and centering barrels on the female part which are carried by lateral ears of the support plate of the male part and of the base of the female part.

Ces oreilles latérales présentent également des trous pour la fixation des parties mâle et femelle sur leur support respectif.These lateral ears also have holes for fixing the male and female parts on their respective support.

Avantageusement, dans chaque trou de l'embase, la douille est montée flottante en prévoyant une collerette extérieure sur le bord de sa partie creuse qui vient en butée contre un alésage du trou et une rondelle associée à un écrou qui retiennent la douille dans ledit trou.Advantageously, in each hole of the base, the sleeve is mounted floating by providing an external collar on the edge of its hollow part which abuts against a bore in the hole and a washer associated with a nut which retains the sleeve in said hole. .

Avantageusement, la broche présente, côté joint élastique, une collerette extérieure qui vient en butée contre l'épaulement d'un deuxième alésage et, côté opposé, un anneau d'arrêt logé dans une rainure extérieure qui retient la broche dans le trou.Advantageously, the spindle has, on the elastic seal side, an external flange which abuts against the shoulder of a second bore and, on the opposite side, a stop ring housed in an external groove which retains the spindle in the hole.

Avantageusement, la broche se termine par un fût à sertir pour recevoir l'extrémité d'un câble souple.Advantageously, the spindle ends in a barrel to be crimped to receive the end of a flexible cable.

D'autres caractéristiques et avantages de la présente invention apparaîtront à la lecture de la description suivante d'un exemple particulier de réalisation, ladite description étant faite en relation avec le dessin en annexe dans lequel :

  • la figure 1 est une vue d'ensemble en perspective cavalière des parties mâle et femelle d'un bornier de puissance selon l'invention, et
  • la figure 2 est une vue en coupe agrandie d'une douille et d'une broche correspondante du bornier de puissance selon l'invention ainsi qu'une vue en coupe dans un autre plan d'un pion et d'un canon de centrage des deux parties du bornier.
Other characteristics and advantages of the present invention will appear on reading the following description of a particular embodiment, said description being made in relation to the appended drawing in which:
  • FIG. 1 is an overall perspective view of the male and female parts of a power terminal block according to the invention, and
  • Figure 2 is an enlarged sectional view of a socket and a corresponding pin of the terminal block power according to the invention and a sectional view in another plane of a pin and a centering gun of the two parts of the terminal block.

Un connecteur ou bornier de puissance du type à broches selon l'invention comprend une partie femelle 1 et une partie mâle 2. La partie femelle 1 est fixée sur l'aéronef tandis que la partie mâle 2 fait partie d'un appareil démontable (non représenté), par exemple un dispositif de distribution électrique. S'il s'agit d'un tel dispositif de distribution, la partie femelle 1 est connectée à des conducteurs d'arrivée de l'énergie électrique, tels que celui référencé 3, qui sont fixés par un système de cosses, rondelles et écrous sur les extrémités filetées de douilles telles que celle référencée 4. Dans les autres extrémités creuses des douilles viennent se loger les broches, telles que celle référencée 5, de la partie mâle 2.A connector or power terminal block of the pin type according to the invention comprises a female part 1 and a male part 2. The female part 1 is fixed to the aircraft while the male part 2 is part of a removable device (not shown), for example an electrical distribution device. If it is such a distribution device, the female part 1 is connected to conductors of electrical energy, such as that referenced 3, which are fixed by a system of lugs, washers and nuts on the threaded ends of sockets such as that referenced 4. In the other hollow ends of the sockets are housed the pins, such as that referenced 5, of the male part 2.

Le bornier de la figure 1 est prévu pour recevoir l'énergie électrique de quatres générateurs triphasés différents sur douze conducteurs par groupe de trois plus deux conducteurs de masse, d'où un connecteur à quatorze bornes. Deux des quatres générateurs sont les générateurs de puissance de l'aéronef en fonctionnement normal, un troisième est porté par l'équipement de piste pour le démarrage des moteurs et un quatrième est un générateur auxiliaire qui est utilisé en cas d'indisponibilité des trois premiers.The terminal block in Figure 1 is designed to receive electrical energy from four different three-phase generators on twelve conductors in groups of three plus two ground conductors, hence a connector with fourteen terminals. Two of the four generators are the power generators of the aircraft in normal operation, a third is carried by the runway equipment for starting the engines and a fourth is an auxiliary generator which is used in the event of the unavailability of the first three .

Dans le cas particulier d'un appareil de distribution électrique, ce dernier réalise essentiellement deux fonctions, l'une qui est d'effectuer les connexions avec le ou les générateurs qui doivent être utilisés et l'autre de distribuer l'énergie électrique reçue sur les bornes actives aux différents équipements de l'aéronef. La première fonction est réalisée à l'aide d'un contacteur de puissance qui comprend des relais de commutation et qui est fixé de manière démontable sur l'appareil de distribution électrique. La deuxième fonction est réalisée par l'intermédiaire de disjoncteurs associés à des circuits électroniques de contrôle et de commande.In the particular case of an electrical distribution apparatus, the latter essentially performs two functions, one which is to make the connections with the generator or generators which must be used and the other to distribute the electrical energy received over the active terminals at the various equipment items of the aircraft. The first function is carried out using a power contactor which includes switching relays and which is detachably attached to the electrical distribution apparatus. The second function is carried out by means of circuit breakers associated with electronic control and command circuits.

La partie femelle 1 comprend une embase rectangulaire 6 qui présente une surface plate 7 du côté de la partie mâle et des alvéoles 8 sur le côté opposé pour la séparation et le maintien des conducteurs 3. Les alvéoles, au nombre de quatorze, sont fermées par un capot 9 qui est fixé par des vis (non représentés) sur la partie non alvéolée de l'embase. Le pourtour de l'embase 6 présente des oreilles ou pattes de fixation, telles que celle référencée 10, au nombre de cinq dont trois sur les côtés latéraux et deux aux extrémités. Ces oreilles ont chacune un trou 11 pour le passage d'une vis de fixation tandis que les trois oreilles latérales ont en outre un trou 12 pour un canon de centrage qui coopère avec un pion de centrage porté par la partie mâle 2, tel que celui référencé 16.The female part 1 comprises a rectangular base 6 which has a flat surface 7 on the side of the male part and of the cells 8 on the opposite side for the separation and the maintenance of the conductors 3. The cells, fourteen in number, are closed by a cover 9 which is fixed by screws (not shown) on the non-cellular part of the base. The periphery of the base 6 has ears or fixing lugs, such as that referenced 10, five in number, three of which are on the lateral sides and two at the ends. These ears each have a hole 11 for the passage of a fixing screw while the three lateral ears also have a hole 12 for a centering barrel which cooperates with a centering pin carried by the male part 2, such as that referenced 16.

A chaque alvéole, l'embase est percée d'un trou pour la mise en place et le maintien d'une douille femelle qui sera décrite de manière plus détaillée en relation avec la figure 2.At each cell, the base is pierced with a hole for the establishment and maintenance of a female socket which will be described in more detail with reference to FIG. 2.

La partie mâle 2 comprend une plaque rectangulaire 20 dont le pourtour présente également des oreilles latérales, telles que celle référencée 15, qui servent à la fixation de cette partie mâle sur l'appareil de distribution électrique ainsi qu'au centrage des parties mâle et femelle. Pour la fixation, chaque oreille est munie d'un trou 13 pour le passage d'une vis. Pour le centrage, chaque oreille est munie d'un pion de centrage, tel que celui référencé 16, qui coopère avec le canon de centrage correspondant 12 de la partie femelle.The male part 2 comprises a rectangular plate 20, the periphery of which also has lateral ears, such as that referenced 15, which are used for fixing this male part to the electrical distribution apparatus as well as for centering the male and female parts. . For fixing, each ear is provided with a hole 13 for the passage of a screw. For centering, each lug is provided with a centering pin, such as that referenced 16, which cooperates with the corresponding centering barrel 12 of the female part.

La plaque 20 est percée en son milieu de quatorze trous alignés pour la mise en place et le maintien de quatorze broches mâles qui seront décrites de manière détaillée en relation avec la figure 2. Du côté de la partie femelle, ces broches sont prévues pour s'enficher dans les douilles correspondantes ; de l'autre côté, elles sont connectées à des conducteurs, tels que celui référencé 18. Pour la séparation des conducteurs 18 entre eux, ce coté de la plaque 14 est muni de cloisons telles que celle référencée 19.The plate 20 is drilled in the middle of fourteen aligned holes for the establishment and maintenance of fourteen male pins which will be described in detail in relation to Figure 2. On the side of the female part, these pins are provided for s '' insert into the corresponding sockets; on the other side, they are connected to conductors, such as the one referenced 18. For the separation of the conductors 18 between them, this side of the plate 14 is provided with partitions such as that referenced 19.

Comme le montre de manière détaillée la vue en coupe de la figure 2, la partie mâle du bornier portée par l'appareil démontable comprend la plaque 20 percée d'un nombre de trous identiques, tels que celui référencé 21 pour la borne d'extrémité 22. Côté support, ce trou 21 se termine par un alésage intérieur 23 et un alésage extérieur 24. Une broche 25 de forme cylindrique de révolution est prévue pour s'emmancher par le haut dans le trou 21 et présente une collerette 31 qui s'appuie sur l'épaulement de l'alésage intérieur 23. Cette broche se termine, du côté support, par une fiche 26 qui coopère avec la douille correspondante du support. L'autre côté de la broche se termine par un fût ou cosse à sertir 27 pour recevoir un câble souple 18. Une rainure 29 taillée dans la paroi extérieure de la broche 25 entre le fût à sertir 27 et la collerette 31 reçoit un anneau d'arrêt ou clip 30 qui sert de retenue de la broche 25 et limite le déplacement de la broche vers le support. De même, la collerette 31 limite le déplacement de la broche vers l'appareil. Enfin, un joint annulaire élastique 32 est collé dans l'alésage extérieur 24 et entoure la fiche de contact 26 ; l'épaisseur de ce joint est supérieure à la profondeur de l,alésage 24, ce qui permettra de bloquer la broche contre l'épaulement de l'alésage 23 lorsque le joint sera comprimé contre la douille correspondante du support.As shown in detail in the sectional view of FIG. 2, the male part of the terminal block carried by the removable device comprises the plate 20 pierced with a number of identical holes, such as that referenced 21 for the end terminal 22. On the support side, this hole 21 ends with an internal bore 23 and an external bore 24. A pin 25 of cylindrical shape of revolution is provided for fitting from above into the hole 21 and has a collar 31 which rests on the shoulder of the internal bore 23. This pin ends, on the support side, by a plug 26 which cooperates with the corresponding socket of the support. The other side of the spindle ends in a barrel or crimping lug 27 to receive a flexible cable 18. A groove 29 cut in the outer wall of the spindle 25 between the crimping barrel 27 and the flange 31 receives a ring d 'stop or clip 30 which serves to retain the spindle 25 and limits the movement of the spindle towards the support. Similarly, the flange 31 limits the movement of the spindle towards the device. Finally, an elastic annular seal 32 is glued into the outer bore 24 and surrounds the contact plug 26; the thickness of this seal is greater than the depth of the bore 24, which will allow the pin to be blocked against the shoulder of the bore 23 when the seal is compressed against the corresponding socket of the support.

Chaque oreille latérale de la partie mâle comporte un pion de centrage 16 qui est fixé par une vis 34 et qui coopère avec un canon de centrage. Ce canon est réalisé par un perçage muni d'un mandrin 46.Each lateral lug of the male part comprises a centering pin 16 which is fixed by a screw 34 and which cooperates with a centering barrel. This barrel is produced by a bore provided with a mandrel 46.

La partie femelle du bornier, qui est représentée sur la partie supérieure de la figure 2, est constituée de l'embase 6 qui est percée de trous tels que celui référencé 36, chaque trou étant prévu pour recevoir une douille 37. Cette douille 37 comprend une partie inférieure creuse 38 qui réalise le contact avec la fiche 26 de la partie mâle et une partie supérieure filetée 39 sur laquelle vient se brancher le conducteur électrique 3 (figure 1) terminé par une cosse 40, la cosse étant maintenue en place et serrée par des écrous 41 et 42 et une rondelle 14. Une rondelle 43 serrée par l'écrou 42 sert d'anneau d'arrêt de la douille en direction du bas. Le déplacement de la douille vers le haut est limité par une collerette 44 qui constitue le bord de la douille creuse et qui vient en butée contre l'épaulement d'un alésage 45. Cette douille est mise en place dans le trou 36 par le bas, les écrous et les rondelles ayant été enlevés préalablement. Par suite de l'écartement entre la collerette 45 et la rondelle 43 par rapport à la longueur du perçage 36, le montage douille 37 - trou 36 est flottant.The female part of the terminal block, which is represented on the upper part of FIG. 2, consists of the base 6 which is pierced with holes such as that referenced 36, each hole being provided for receiving a socket 37. This socket 37 comprises a hollow lower part 38 which makes contact with the plug 26 of the male part and a threaded upper part 39 to which is connected the electrical conductor 3 (FIG. 1) terminated by a terminal 40, the terminal being held in place and tightened by nuts 41 and 42 and a washer 14. A washer 43 tightened by the nut 42 serves as a stop ring for the sleeve in the direction of the bottom. The displacement of the sleeve upward is limited by a flange 44 which constitutes the edge of the hollow sleeve and which abuts against the shoulder of a bore 45. This sleeve is placed in the hole 36 from the bottom , the nuts and washers having been removed beforehand. As a result of the spacing between the flange 45 and the washer 43 relative to the length of the bore 36, the socket assembly 37 - hole 36 is floating.

On remarquera que le fond de la partie creuse 38 de la douille 37 ainsi que le fond du fût à sertir 27 présentent un trou de communication 50 qui permet l'évacuation de l'humidité et des saletés.It will be noted that the bottom of the hollow part 38 of the sleeve 37 as well as the bottom of the crimp barrel 27 have a communication hole 50 which allows the evacuation of moisture and dirt.

Lorsque la partie mâle est enfichée sur le support femelle et pressée contre ce dernier, le joint 32 vient en contact avec le pourtour de la collerette 44 et bloque la douille 37 vers le haut de la figure. De même, la fiche mâle est repoussée vers le bas, ce qui la bloque également en position.When the male part is plugged into the female support and pressed against the latter, the seal 32 comes into contact with the periphery of the flange 44 and blocks the socket 37 towards the top of the figure. Similarly, the male plug is pushed down, which also locks it in position.

Les parties mâles et femelles sont maintenues pressée l'une contre l'autre par des moyens solidaires de l'aéronef et de l'appareil démontable qui n'ont pas été représentés sur les figures.The male and female parts are kept pressed against one another by means integral with the aircraft and with the removable device which have not been shown in the figures.
