Description

L'invention se rapporte à un boîtier de connectique du type comportant une plaque de base formant support pour une plaque de circuit imprimé et un capot de fermeture.The invention relates to a connector housing of the type comprising a base plate forming a support for a printed circuit board and a closing cap.

Les boîtiers de connectique connus sont réalisés en fonction du type de connecteur et en fonction de la direction de la sortie du connecteur. Une telle direction peut être parallèle ou perpendiculaire à la plaque de base.Connector housings known are made according to the type of connector and depending on the direction of the output of the connector. Such a direction may be parallel or perpendicular to the base plate.

En particulier, dans les autobus ou les autocars, on utilise des boîtiers universels qui sont connectés à des bus de multiplexage et qui servent à gérer des entrées / sorties. Le nombre et la disposition de ces boîtiers varient en fonction de la personnalisation du véhicule requise par le client, de sorte que ces boîtiers peuvent être disposés à différents emplacements dans le véhicule. Suivant la configuration de ces emplacements, ces boîtiers doivent avoir des connecteurs dont les contacts sont soit parallèles, soit perpendiculaires à la plaque de base du boîtier. Une telle installation des boîtiers « à la carte » nécessite donc, pour l'équipementier du véhicule, de disposer de boîtiers de différents modèles en fonction du type de connecteur et en particulier de la direction de la sortie du connecteur désirée pour chaque emplacement.In particular, in buses or coaches, universal boxes are used which are connected to multiplexing buses and which serve to manage inputs / outputs. The number and arrangement of these boxes vary according to the personalization of the vehicle required by the customer, so that these boxes can be arranged at different locations in the vehicle. Depending on the configuration of these locations, these boxes must have connectors whose contacts are either parallel or perpendicular to the base plate of the housing. Such an installation of boxes "a la carte" therefore requires, for the equipment manufacturer of the vehicle, to have housings of different models depending on the type of connector and in particular the direction of the output of the desired connector for each location.

De plus, certains boitiers sont susceptibles d'être exposés à des projections de liquide, ce qui nécessite des boitiers et des connecteurs étanches et multiplie encore le nombre de modèles de boitiers.In addition, some cases are likely to be exposed to liquid projections, which requires sealed boxes and connectors and further multiplies the number of models of cases.

US5548481 est considéré comme étant l'état de la technique le plus proche. US5548481 is considered to be the closest state of the art.

L'invention a pour objet un boîtier de connectique qui permette d'acceuillir n'importe quel type de connecteurs, étanche ou non étanche, dont les sorties peuvent être orientées, suivant les cas, suivant une direction parallèle ou perpendiculaire au plan du boîtier.The invention relates to a connector housing that can accommodate any type of connectors, waterproof or not sealed, whose outputs can be oriented, depending on the case, in a direction parallel to or perpendicular to the plane of the housing.

A cet effet, l'invention concerne un boîtier de connectique comportant au moins une première zone d'accueil d'au moins un circuit électronique et au moins une seconde zone d'accueil d'au moins un connecteur, lesdites première et seconde zones étant internes audit boîtier, ce boitier étant remarquable en ce que lesdites première et deuxième zones sont adaptées pour recevoir un support portant ledit circuit électronique et ledit connecteur et s'étendant de l'une desdites zones à l'autre, et en ce que ledit boitier comporte des moyens d'étanchéité pour isoler de manière étanche ladite première zone interne de ladite seconde zone interne.For this purpose, the invention relates to a connector housing comprising at least a first reception zone of at least one electronic circuit and at least a second reception zone of at least one connector, said first and second zones being internal to said housing, this housing being remarkable in that said first and second zones are adapted to receive a support carrying said electronic circuit and said connector and extending from one of said zones to the other, and in that said housing comprises sealing means for sealingly isolating said first internal zone of said second internal zone.

Ainsi, le compartiment réservé à l'électronique est protégé de manière étanche et l'autre compartiment réservé à la connectique n'est plus, contrairement à ce qui est le cas dans les boîtiers connus, enfermé sous le capot. L'invention permet ainsi, d'une part, la réalisation de capots standards et donc une réduction de coût de fabrication et, d'autre part, le montage dans la deuxième zone de connecteurs de tous types, étanches ou non, avec des sorties orientées indifféremment suivant des directions qui peuvent être parallèles ou perpendiculaires au plan du boîtier.Thus, the compartment reserved for electronics is sealed and the other compartment reserved for connectors is no longer, contrary to what is the case in known cases, locked under the hood. The invention thus makes it possible, on the one hand, to produce standard covers and thus to reduce manufacturing costs and, on the other hand, to mount in the second zone connectors of all types, sealed or not, with outlets. oriented indifferently in directions that may be parallel or perpendicular to the plane of the housing.

Le boîtier de connectique suivant l'invention peut également comporter les caractéristiques suivantes, prises séparément ou en combinaison :

  • Ladite zone de connectique est conformée pour recevoir des connecteurs disposés suivant l'une d'au moins deux orientations différentes ;
  • Le boîtier comporte une plaque de base apte à recevoir au moins une plaque de circuit imprimé constituant ledit support, et un capot de fermeture, ladite plaque de base comportant :
  • un premier compartiment définissant avec le capot en position de fermeture ladite première zone pour accueillir au moins une première partie de ladite plaque de circuit imprimée comportant ledit circuit électronique, et
  • un second compartiment définissant ladite seconde zone pour accueillir au moins une seconde partie de la plaque de circuit imprimé comportant ledit connecteur ;
  • Lesdits moyens d'étanchéité comportent un premier joint d'étanchéité disposé entre la plaque de base et une face de la plaque de circuit imprimé, et un deuxième joint d'étanchéité disposé entre la face opposée de la plaque de circuit imprimé et le capot;
  • Le premier joint est en forme de boucle continue et épouse le contour dudit premier compartiment de ladite plaque de base.
  • La plaque de base comporte un rebord périphérique en saillie et une cloison en saillie séparant la première zone de la seconde zone. Une telle cloison et le capot permettent l'écrasement des premier et deuxième joints contre la plaque de circuit imprimé.
  • Le boîtier de connectique comporte un second capot de protection des connecteurs. Un tel second capot présente avantageusement une hauteur sensiblement identique à celle du premier capot pour ne pas augmenter l'encombrement du boîtier.
  • Le second capot est réalisé translucide pour, notamment, rendre visible une diode électroluminescente disposée dans la seconde zone du boîtier, indiquant l'état de fonctionnement du circuit électronique enfermé dans la première zone du boîtier.
  • Le second capot est réalisé en matière plastique.
  • La plaque de base et le capot sont réalisés en métal ou en matière plastique.
The connector housing according to the invention may also include the following features, taken separately or in combination:
  • Said connection zone is shaped to receive connectors arranged in one of at least two different orientations;
  • The housing comprises a base plate adapted to receive at least one printed circuit board constituting said support, and a closure cover, said base plate comprising:
  • a first compartment defining with the cover in the closed position said first zone to accommodate at least a first portion of said printed circuit board comprising said electronic circuit, and
  • a second compartment defining said second area for accommodating at least a second portion of the printed circuit board having said connector;
  • Said sealing means comprises a first seal disposed between the base plate and a face of the printed circuit board, and a second seal disposed between the opposite face of the printed circuit board and the cover;
  • The first seal is in the form of a continuous loop and conforms to the contour of said first compartment of said base plate.
  • The base plate has a protruding peripheral rim and a projecting partition separating the first zone from the second zone. Such a partition and the cover allow crushing of the first and second seals against the printed circuit board.
  • The connector housing includes a second protective cover connectors. Such a second cover advantageously has a height substantially identical to that of the first cover so as not to increase the bulk of the housing.
  • The second cover is made translucent to, in particular, make visible a light emitting diode disposed in the second zone of the housing, indicating the operating state of the electronic circuit enclosed in the first zone of the housing.
  • The second hood is made of plastic.
  • The base plate and the cover are made of metal or plastic.

L'invention concerne également un ensemble de connectique comportant un boîtier de connectique tel que défini ci-dessus, une plaque de circuit imprimé et des connecteurs fixés sur ladite plaque de circuit imprimé.The invention also relates to a connector assembly comprising a connector housing as defined above, a printed circuit board and connectors fixed on said printed circuit board.

Suivant l'invention, les connecteurs d'un tel ensemble, fixés sur la plaque de circuit imprimé, sont noyés partiellement dans une résine d'étanchéité.According to the invention, the connectors of such an assembly, fixed on the printed circuit board, are partly embedded in a sealing resin.

Suivant un mode de réalisation conforme à l'invention, on prévoit qu'un tel ensemble comporte une diode électroluminescente dans la seconde zone du boîtier de connectique et un second capot de protection des connecteurs réalisé translucide.According to an embodiment according to the invention, it is provided that such an assembly comprises a light-emitting diode in the second zone of the connector housing and a second protective cap connectors made translucent.

L'invention sera davantage comprise à la lumière des modes de réalisation qui vont maintenant être présentés, en faisant référence aux figures annexées parmi lesquelles :

  • la figure 1 est une vue en perspective éclatée d'un ensemble de connectique selon un premier mode de réalisation conforme à l'invention ;

  • et la figure 5 est une vue en perspective arrière de l'ensemble illustré en figure 4.
The invention will be further understood in the light of the embodiments which will now be presented, with reference to the appended figures among which:
  • the figure 1 is an exploded perspective view of a set of connectors according to a first embodiment according to the invention;
  • the figure 2 is a perspective view of the set shown in figure 1 once these various constituents are assembled;

  • the figure 4 is a perspective view of the set shown in figure 3 once these various constituents are assembled;
  • and the figure 5 is a rear perspective view of the assembly illustrated in figure 4 .

Sur les figures 1 et 2, l'ensemble de connectique selon l'invention comporte un boîtier de connectique composé d'une plaque de base 1 et de deux capots 3 et 5.On the figures 1 and 2 , the set of connectors according to the invention comprises a connector housing composed of a base plate 1 and two covers 3 and 5.

La plaque de base 1 est de forme sensiblement rectangulaire. Elle présente un rebord en saillie 11 délimitant son contour, excepté dans deux coins 13 (un seul est montré sur la figure 1) que le rebord en saillie 11 contourne.The base plate 1 is of substantially rectangular shape. It has a protruding flange 11 delimiting its outline, except in two corners 13 (only one is shown on the figure 1 ) that the protruding rim 11 bypasses.

Les coins 13 et une patte 14 présentent des ouvertures traversantes 15 permettant de fixer le boîtier, par vissage ou tout autre moyen équivalent, sur un dispositif (non représenté) destiné à le supporter.The corners 13 and a tab 14 have through openings 15 for fixing the housing, by screwing or other equivalent means, on a device (not shown) for supporting it.

La plaque de base 1 comporte également des plots cylindriques 17 qui font saillie de la surface de la plaque de base 1 à des intervalles réguliers le long du côté intérieur du rebord 11 et qui ont la même hauteur que celui-ci.The base plate 1 also has cylindrical studs 17 which protrude from the surface of the base plate 1 at regular intervals along the inner side of the flange 11 and which have the same height as the latter.

Un orifice de passage axial 19 traverse chaque plot 17 pour permettre la fixation de la plaque de base 1 et du capot 3, au moyen de vis 20.An axial passage opening 19 passes through each stud 17 to allow attachment of the base plate 1 and the cover 3, by means of screws 20.

La plaque 1 présente enfin un renflement ou cloison 21 se présentant sous forme d'une baguette ou nervure faisant saillie de la surface de la plaque du même côté que le rebord 11 et sur la même hauteur que celui-ci. Cette cloison 21 traverse la plaque de part en part en joignant deux bords opposés du rebord 11.The plate 1 finally has a bulge or partition 21 in the form of a rod or rib projecting from the surface of the plate on the same side as the flange 11 and on the same height as this one. This partition 21 crosses the plate from one side to the other by joining two opposite edges of the flange 11.

La cloison délimite ainsi une première zone 23 destinée à accueillir les circuits électroniques d'une plaque de circuit imprimé 7, cette première zone étant appelée première zone dédiée à l'électronique, et une seconde zone 25 destinée à accueillir les connecteurs fixés à la plaque de circuit imprimé le long de l'un de ses bords, cette seconde zone étant appelée seconde zone dédiée à la connectique. La plaque de circuit imprimé 7 est fixée à la hauteur voulue dans le boitier 1 par des moyens conventionnels qui n'ont pas été représentés pour la clarté du dessin.The partition thus delimits a first zone 23 intended to accommodate the electronic circuits of a printed circuit board 7, this first zone being called the first zone dedicated to the electronics, and a second zone 25 intended to receive the connectors fixed to the plate. circuit board along one of its edges, this second zone being called second zone dedicated to the connectors. The printed circuit board 7 is fixed to the desired height in the housing 1 by conventional means which have not been shown for clarity of the drawing.

La plaque de base 1 est réalisée en métal, par moulage d'une seule pièce.The base plate 1 is made of metal, by molding in one piece.

Le capot 3 a pour fonction d'enfermer et isoler la partie électronique de la plaque de circuit imprimée 7 (non représentée). Le capot 3 présente ainsi un bord 31 dont le contour est complémentaire de celui défini ensemble par une partie du rebord 11 et par la cloison 21 de la plaque de base 1, qui délimitent la zone 23 dédiée à l'électronique.The purpose of the cover 3 is to enclose and isolate the electronic part of the printed circuit board 7 (not shown). The cover 3 thus has an edge 31 whose contour is complementary to that defined together by a portion of the flange 11 and the partition 21 of the base plate 1, which define the zone 23 dedicated to the electronics.

De manière en soi connue de l'homme du métier, le capot 3 présente des stries ou ailettes 33 formant radiateurs et favorisant le refroidissement des circuits, et est équipé d'un bouchon 35 du type « pastille cortex pour aimant », permettant d'éviter la condensation dans le boîtier.In a manner known to those skilled in the art, the cover 3 has ridges or fins 33 forming radiators and promoting the cooling of the circuits, and is equipped with a plug 35 of the type "pastille cortex magnet", allowing avoid condensation in the housing.

Le capot 3 comporte également des moyens d'accueil et de fixation des vis 20 traversant la plaque de base 1. Pour simplifier la lecture de la figure 1, de tels moyens n'ont pas été représentés. Ils sont toutefois connus de l'homme du métier. Ils consistent par exemple en des trous borgnes taraudés réalisés dans le capot 3.The cover 3 also comprises means for receiving and fixing the screws 20 passing through the base plate 1. To simplify the reading of the figure 1 such means have not been shown. They are, however, known to those skilled in the art. They consist for example of threaded blind holes made in the cover 3.

Tout comme la plaque de base 1, le capot 3 est réalisé en une seule pièce métallique moulée.Like the base plate 1, the cover 3 is made of a single molded metal part.

Le boîtier de connectique illustré sur les figures 1 et 2 comporte également deux joints d'étanchéité 37 et 39 réalisés en matière élastiquement déformable et étanche aux liquides, du type caoutchouc ou silicone.The connector box shown on the figures 1 and 2 also comprises two seals 37 and 39 made of elastically deformable material and liquid-tight, of the rubber or silicone type.

Le joint 37 forme une boucle sensiblement rectangulaire, de profil (c'est à dire de longueur et proportions) sensiblement identique à celui du bord du capot 3 pour en épouser le contour. Le joint 37 est destiné à venir s'appliquer contre le rebord 11 et la cloison 21 et présente sur trois côtés une section en U de sorte à accueillir l'extrémité du bord 31 du capot 3 sur trois de ses côtés. Sur son quatrième côté, destiné à être serré entre la cloison 21 et la face inférieure de la plaque de circuit imprimé 7 tournée vers la plaque de base 1, le joint 37 est de préférence plan et de plus faible hauteur que sur les trois autres côtés à section en U.The seal 37 forms a substantially rectangular loop, of profile (ie length and proportions) substantially identical to that of the edge of the cover 3 to marry the contour. The seal 37 is intended to be applied against the flange 11 and the partition 21 and has on three sides a U-shaped section so as to accommodate the end of the edge 31 of the cover 3 on three of its sides. On its fourth side, intended to be clamped between the partition 21 and the underside of the printed circuit board 7 turned towards the base plate 1, the seal 37 is plan and lower height than on the other three U-section sides.

Sur la vue éclatée de la figure 1, afin d'illustrer avec clarté les sections en U et plane du joint 37 ainsi que la complémentarité de son contour avec celui du capot 3, le joint 37 a été représenté comme si il était situé au-dessus de la plaque de circuit imprimé 7. Il doit cependant être compris que dans la position assemblée du boitier, le joint 37 est appliqué par ses trois côtés à section en U contre le rebord 11 et que son quatrième côté à section plane est intercalé entre la cloison 21 et la plaque de circuit imprimé 7. La même remarque s'applique à l'égard de la représentation de la figure 3 On the exploded view of the figure 1 in order to clearly illustrate the U and plane sections of the gasket 37 and the complementarity of its contour with that of the cover 3, the gasket 37 has been shown as if it were located above the printed circuit board 7 However, it should be understood that in the assembled position of the housing, the gasket 37 is applied by its three U-section sides against the flange 11 and that its fourth flat-section side is interposed between the partition 21 and the circuit board 7. The same applies with respect to the representation of the figure 3

Le joint 39 est de forme rectiligne et présente une longueur au moins égale à la largeur de la cloison 21 de manière à venir préférentiellement se superposer à chacune de ses deux extrémités au joint 37 pour assurer une continuité de l'étanchéité autour de la première zone 23. De préférence, le quatrième côté 36 du capot 3 destiné à venir au droit de la cloison 21 est échancré sur une longueur complémentaire de celle du joint 39 et il est apte à être reçue dans l'ouverture du U. Le joint 39 peut ainsi être écrasé entre le rebord 36 et la face supérieure de la plaque de circuit imprimée 7 tournée vers le capot 3.The gasket 39 is rectilinear in shape and has a length at least equal to the width of the partition 21 so as to preferentially be superimposed on each of its two ends at the gasket 37 to ensure continuity of sealing around the first zone 23. Preferably, the fourth side 36 of the cover 3 intended to come to the right of the partition 21 is indented on a length complementary to that of the seal 39 and is adapted to be received in the opening of the U. The seal 39 can thus being crushed between the flange 36 and the upper face of the printed circuit board 7 turned towards the cover 3.

La hauteur du joint 39, celle du joint 37 tant sur ses trois côtés à section en U que sur son quatrième côté, et la distance entre la cloison 21 et le bord échancré 36 du capot 3, sont choisies en fonction de l'épaisseur de la plaque de circuit imprimé 7 de manière à assurer un serrage sensiblement uniforme du capot 3 contre les joints 37 et 39 dans la position assemblée du boitier.The height of the gasket 39, that of the gasket 37 on its three U-section sides as well as its fourth side, and the distance between the partition 21 and the notched edge 36 of the cover 3, are chosen as a function of the thickness of the gasket. the printed circuit board 7 so as to ensure a substantially uniform tightening of the cover 3 against the seals 37 and 39 in the assembled position of the housing.

Ainsi, lorsque le capot 3 est fixé sur la plaque de base 1, une partie de la plaque de circuit imprimé 7, présentant notamment les circuits électroniques, est totalement enfermée de manière étanche entre le capot 3 et la plaque de base 1 grâce à la présence des joints 37 et 39. Ces joints 37 et 39 assurent une double étanchéité, de chaque côté de la plaque de circuit imprimée 7 au niveau de la cloison 21 de la plaque de base 1, c'est-à-dire à la limite des zones dédiées respectivement à l'électronique et à la connectique.Thus, when the cover 3 is fixed on the base plate 1, a portion of the printed circuit board 7, in particular having the electronic circuits, is totally sealed between the cover 3 and the base plate 1 thanks to the presence of the seals 37 and 39. These seals 37 and 39 provide a double seal, on each side of the printed circuit board 7 at the partition 21 of the base plate 1, that is to say at the limit areas dedicated respectively to electronics and connectors.

Le capot 3 et de la plaque de base 1 en métal, d'une part, et les moyens d'isolation et d'étanchéité 37, 39 constitués par les joints, d'autre part, assurent non seulement une protection du circuit électronique par rapport à des fluides extérieurs, mais également une isolation électromagnétique des circuits électroniques.The cover 3 and the metal base plate 1, on the one hand, and the insulation and sealing means 37, 39 constituted by the seals, on the other hand, ensure not only a protection of the electronic circuit with respect to external fluids, but also an electromagnetic isolation of the electronic circuits.

On voit sur la figure 1 trois connecteurs 41, 43 et 45 de tailles différentes, alignés le long de l'un des bords de la plaque de circuit imprimé 7.We see on the figure 1 three connectors 41, 43 and 45 of different sizes aligned along one edge of the printed circuit board 7.

Dans le cadre de ce mode de réalisation, les broches des connecteurs 41 à 45 sont orientés suivant une direction parallèle au plan de la plaque de base 1.In the context of this embodiment, the pins of the connectors 41 to 45 are oriented in a direction parallel to the plane of the base plate 1.

Les connecteurs 41, 43, 45 sont fixés sur la plaque de circuit imprimé 7 de manière en soi connue, par exemple par des vis 40The connectors 41, 43, 45 are fixed to the printed circuit board 7 in a manner known per se, for example by screws 40

Pour assurer une étanchéité optimale, les organes de fixation 40 des connecteurs 41, 43, 45 sur la plaque de circuit imprimé 7 peuvent être noyés dans une résine.To ensure optimum sealing, the fasteners 40 of the connectors 41, 43, 45 on the printed circuit board 7 may be embedded in a resin.

Le second capot 5 est prévu pour protéger davantage les connecteurs 41, 43, 45, notamment en empêchant tout accès accidentel aux organes de fixation 40 des connecteurs sur la plaque de circuit imprimé 7.The second cover 5 is provided to further protect the connectors 41, 43, 45, in particular by preventing any accidental access to the fasteners 40 of the connectors on the printed circuit board 7.

Le second capot 5 est compartimenté pour accueillir chacun des trois connecteurs 41, 43, 45. Il est par ailleurs ouvert sur l'un de ses côtés pour laisser libre accès aux broches de connexion 42.The second cover 5 is compartmentalized to accommodate each of the three connectors 41, 43, 45. It is also open on one of its sides to allow free access to the connection pins 42.

Le capot 5 présente, par ailleurs, des ouvertures traversantes 47 à ses extrémités pour sa fixation par vissage 49 dans des trous taraudés 44 s'étendant dans des plots 46 ménagés, dans la zone 25, contre le rebord périphérique de la plaque de base 1..The cover 5 has, moreover, through openings 47 at its ends for its fixing by screwing 49 in tapped holes 44 extending in studs 46 formed in the zone 25 against the peripheral rim of the base plate 1 ..

Le capot 5 présente également des guides de lumière transparents 51 permettant une meilleure visibilité d'une diode électroluminescente qui est reliée au circuit électronique de la plaque.The cover 5 also has transparent light guides 51 allowing better visibility of a light emitting diode which is connected to the electronic circuit of the plate.

Cette diode n'a pas été représentée pour des raisons de clarté des figures. Elle a pour fonction de témoigner du bon fonctionnement du circuit électronique, sans avoir à ouvrir le boîtier pour s'en assurer.This diode has not been shown for the sake of clarity of the figures. Its function is to testify to the good functioning of the electronic circuit, without having to open the case to make sure of it.

Afin de permettre à un utilisateur de visualiser cette diode, le capot 5 est réalisé en matière plastique translucide.In order to allow a user to view this diode, the cover 5 is made of translucent plastic material.

Les figures 3 à 5 montrent un autre mode de réalisation d'un ensemble de connectique et d'un boîtier selon l'invention. Les numéros de références ont été maintenus pour désigner les éléments communs à ceux du mode de réalisation des figures 1 et 2.The Figures 3 to 5 show another embodiment of a set of connectors and a housing according to the invention. The reference numbers have been maintained to indicate the elements common to those of the embodiment of the figures 1 and 2 .

Dans le mode de réalisation montré sur les figures 3 à 5, des connecteurs 52, 53, 54 ; 55 et 56 sont alignés suivant la longueur de la plaque de circuit imprimé, et fixés de manière connue sur son bord (alors que suivant le mode de réalisation des figures 1 et 2, les connecteurs sont fixés suivant la largeur de la plaque de circuit imprimé 7).In the embodiment shown on the Figures 3 to 5 connectors 52, 53, 54; 55 and 56 are aligned along the length of the printed circuit board, and fixed in a known manner on its edge (whereas according to the embodiment of FIG. figures 1 and 2 , the connectors are fixed according to the width of the printed circuit board 7).

Par ailleurs, les connecteurs 52 à 56 présentent des sorties, c'est-à-dire des broches 42, orientées suivant des directions perpendiculaires au plan de la plaque de base 1.Moreover, the connectors 52 to 56 have outlets, that is to say pins 42, oriented in directions perpendicular to the plane of the base plate 1.

Le boîtier de connectique comporte toutefois toujours deux zones, l'une 23 dédiée à l'électronique et l'autre 25 dédiée à la connectique.The connector housing however still has two areas, one 23 dedicated to electronics and the other 25 dedicated to the connector.

Ces deux zones 23 et 25 sont définies sur la plaque de base de part et d'autre d'une cloison 21 qui rejoint deux côtés opposés du rebord 11 de la plaque de base 1.These two zones 23 and 25 are defined on the base plate on either side of a partition 21 which joins two opposite sides of the flange 11 of the base plate 1.

La zone 25 présente des moyens pour évacuer tout résidu d'eau qui se condenserait au niveau des connecteurs. Ces moyens comprennent notamment une ouverture 63 qui est réalisée à travers la plaque 1.The zone 25 has means for evacuating any water residue that would condense at the connectors. These means include an opening 63 which is made through the plate 1.

La plaque de base 1 comporte, non pas deux, mais quatre coins percés 57 pour la fixation de l'ensemble connectique sur un dispositif.The base plate 1 comprises, not two, but four pierced corners 57 for fixing the connector assembly on a device.

La figure 3 montre également cinq condensateurs chimiques 59 soudés au circuit imprimé, qui viennent se loger dans un compartiment 61 du capot 3 quand le capot est fixé sur la plaque de base 1.The figure 3 also shows five chemical capacitors 59 soldered to the printed circuit, which are housed in a compartment 61 of the cover 3 when the cover is fixed on the base plate 1.

Comme on peut le voir sur les figures 1 et 3, un tel compartiment 61 peut présenter différentes formes suivant le mode de réalisation du boîtier selon l'invention.As can be seen on the figures 1 and 3 such a compartment 61 may have different shapes according to the embodiment of the housing according to the invention.

De manière générale, on comprend que l'invention autorise la réalisation de toutes sortes d'ensembles de connectique à partir d'un seul boîtier, et en particulier la fixation de connecteurs de toutes sortes sans avoir à modifier le boîtier, grâce à la réalisation de deux zones dans le boîtier dédiées respectivement à l'électronique et à la connectique.In general, it is understood that the invention authorizes the realization of all kinds of connector assemblies from a single housing, and particularly the fixing of connectors of all kinds without having to modify the housing, thanks to the realization of two zones in the housing dedicated respectively to electronics and connectors.

Il doit être compris que dans le premier comme dans le second mode de réalisation, la zone 25 de connectique est adaptée pour recevoir, au choix, des connecteurs ayant des sorties orientées parallèlement ou perpendiculairement au plan de la plaque de base 1, ou bien encore une combinaison de connecteurs suivant ces deux orientations différentes, ce qui confère au boîtier son caractère universel.It should be understood that in the first as in the second embodiment, the zone 25 of connectors is adapted to receive, as desired, connectors having outputs oriented parallel or perpendicular to the plane of the base plate 1, or even a combination of connectors according to these two different orientations, which gives the housing its universal character.

Il devra toutefois être entendu que l'invention n'est pas spécifiquement limitée aux modes de réalisation représentés sur les figures. Par exemple, les deux zones pourraient être définies de part et d'autre d'une cloison en saillie sur la plaque de base qui serait réalisé en V, définissant ainsi une zone dédiée à la connectique sur deux bords adjacents du boîtier.It should be understood, however, that the invention is not specifically limited to the embodiments shown in the figures. For example, the two zones could be defined on either side of a projecting partition on the base plate which would be made in V, thus defining an area dedicated to the connection on two adjacent edges of the housing.

De même, le capot 3, le capot 5 et la plaque de base 1 pourraient être réalisés dans d'autres matériaux que ceux spécifiés dans les exemples décrits sans toutefois sortir du cadre de l'invention. Par exemple, le capot 3 et la plaque de base 1 pourraient être réalisés en matière plastique.Similarly, the cover 3, the cover 5 and the base plate 1 could be made of other materials than those specified in the examples described without departing from the scope of the invention. For example, the cover 3 and the base plate 1 could be made of plastic.

On comprend par ailleurs de ce qui précède que le boîtier et l'ensemble selon l'invention permettent de bien protéger l'électronique de la plaque de circuit imprimé. L'invention permet ainsi de s'affranchir d'une utilisation exclusive de connecteurs étanches, beaucoup plus onéreux que les connecteurs non étanches. Elle permet de proposer ainsi des boîtiers standards qui peuvent accueillir des circuits électroniques et des connecteurs différents, dont les coûts de fabrication sont plus bas que ceux des boîtiers connus, réalisés en fonction d'une combinaison donnée de circuit électronique et de connecteurs étanches.It is also understood from the foregoing that the housing and the assembly according to the invention make it possible to well protect the electronics of the printed circuit board. The invention thus eliminates the exclusive use of sealed connectors, much more expensive than non-waterproof connectors. It makes it possible to offer standard housings that can accommodate different electronic circuits and connectors, whose manufacturing costs are lower than those of known packages, made according to a given combination of electronic circuit and sealed connectors.
