Description

L'invention se rapporte à un connecteur électrique blindé, formé d'un bloc isolant pourvu d'alvéoles propres à recevoir des éléments de contact électriques, logé dans un boîtier de blindage, constitué de deux demi-coquilles métalliques pourvues de moyens d'accouplement complémentaires, ce boîtier étant destiné à être revêtu d'une enveloppe surmoulée en matière isolante.The invention relates to a shielded electrical connector, formed of an insulating block provided with cells suitable for receiving electrical contact elements, housed in a shielding box, consisting of two metal half-shells provided with coupling means. complementary, this box being intended to be coated with a molded envelope of insulating material.

Les connecteurs électriques ayant une conception du type ci-dessus sont notamment décrits et représentés dans les documents FR-2 654 558 et EP-A-0 180 594 qui permettent de parfaitement appréhender la constitution de ces matériels et le problème que soulève leur fabrication. Parmi les difficultés rencontrées figurent, certes les contraintes industrielles, mais également et surtout celles relatives à la continuité électrique du blindage et à la résistance mécanique du boîtier sous l'effet de la pression d'injection, lors du surmoulage de l'enveloppe isolante.The electrical connectors having a design of the above type are in particular described and represented in the documents FR-2 654 558 and EP-A-0 180 594 which make it possible to perfectly apprehend the constitution of these materials and the problem which their manufacture raises. Among the difficulties encountered are, of course, the industrial constraints, but also and above all those relating to the electrical continuity of the shielding and to the mechanical resistance of the housing under the effect of the injection pressure, during the overmolding of the insulating envelope.

Selon le document FR-2 654 558, le problème de la résistance mécanique est apparemment solutionné par un boîtier formé de deux demi-coquilles métalliques, venues d'emboutissage, l'une des demi-coquilles dite "inférieure" étant pourvue d'une jupe latérale comprenant un décrochement s'encastrant dans la demi-coquille dite "supérieure" dont la partie postérieure de la paroi périphérique est pourvue d'ouvertures dans lesquelles viennent s'encliqueter des ergots de verrouillage, de forme complémentaire, prévus sur la face arrière de la jupe de la demi-coquille opposée.According to document FR-2 654 558, the problem of mechanical strength is apparently solved by a housing formed by two metal half-shells, drawn by stamping, one of the so-called "lower" half-shells being provided with a side skirt comprising a recess fitting into the so-called "upper" half-shell, the posterior part of the peripheral wall of which is provided with openings in which locking lugs, of complementary shape, are provided, provided on the rear face of the skirt of the opposite half-shell.

Les deux demi-coquilles sont prolongées à l'arrière par une partie semi-cylindrique de passage des conducteurs électriques, ceinte, en position assemblée, par une ferrule de sertissage. Ici la résistance mécanique et la bonne continuité électrique, pour obtenir l'effet de blindage désiré contre les champs parasites, est recherchée par des nervures de rigidification matricée dans chaque demi-coquille et par l'encastrement partiel desdites coquilles qui comportent, à dessein, un rétreint contre lequel vient s'appuyer la tranche de la jupe de la demi-coquille opposée.The two half-shells are extended at the rear by a semi-cylindrical part for passage of the electrical conductors, surrounded, in the assembled position, by a crimping ferrule. Here, the mechanical strength and good electrical continuity, to obtain the desired shielding effect against stray fields, is sought by stiffening ribs stamped in each half-shell and by the partial embedding of said shells which, by design, a constriction against which the edge of the skirt of the opposite half-shell rests.

La jonction du boîtier de blindage avec le boîtier arrière normalisé, comportant le bloc isolant, est réalisée par une indentation des bords libres avant des demi-coquilles. Des pattes repliées en forme de griffes, obtenues par découpage/emboutissage puis écrouissage, sont en effet alignées à intervalles réguliers sur toute la longueur de ces bords libres et coopèrent, lors de l'accouplement des deux boîtiers, avec des encoches correspondantes pratiquées dans la bride du boîtier arrière.The connection of the shielding box with the standardized rear box, comprising the insulating block, is carried out by indentation of the free edges before the half-shells. Folds folded in the shape of claws, obtained by cutting / stamping and then work hardening, are in fact aligned at regular intervals over the entire length of these free edges and cooperate, during the coupling of the two housings, with corresponding notches practiced in the rear case flange.

Malgré cette conception la pression d'injection lors du surmoulage de l'enveloppe isolante risque fort de déformer les coquilles du boîtier de blindage et par suite de transmettre les efforts aux éléments du bloc isolant (entraînant un effet de claquage et de court-circuit) à partir du moment où aucune fuite n'est prévue pour jouer le rôle de limiteur de pression et réguler les surpressions temporaires d'injection.Despite this design, the injection pressure during the overmolding of the insulating envelope is very likely to deform the shells of the shielding box and consequently to transmit the forces to the elements of the insulating block (resulting in a breakdown and short-circuit effect). from the moment when no leakage is foreseen to act as a pressure limiter and regulate the temporary injection overpressures.

En outre les coquilles, bien qu'ayant une certaine symétrie, ne peuvent pas être arbitrairement substituées l'une à l'autre car leur conception est de type complémentaire (mâle et femelle) et nécessite obligatoirement des outils de découpe, notamment des poinçons, de conformation différente.In addition, the shells, although having a certain symmetry, cannot be arbitrarily substituted for one another because their design is of complementary type (male and female) and requires cutting tools, in particular punches, of different conformation.

Selon le document EP-A-0 180 594 la résistance mécanique du boîtier de blindage, lors de l'opération de surmoulage de l'enveloppe isolante, est solutionné par des évents de décharge de pression consistant dans des opercules partiellement cisaillés dans le fond des coquilles et restant, lorsque la pression de moulage est admissible, dans le même plan que ce fond (pour s'opposer à l'intrusion de matière plastique dans le boîtier), mais étant susceptible lorsque la pression franchit un seuil critique de s'effacer vers l'intérieur du boîtier, par articulation des opercules autour des portions non cisaillées, afin de permettre l'extrusion d'une quantité de matière vers l'intérieur dudit boîtier. Cette conception permet un effet de régulation de pression mais n'autorise pas, par contre, le contrôle rigoureux de la masse de matière fluant à l'intérieur du boîtier ce qui risque en cas de pression importante d'affecter les connections électriques, notamment les gaines isolantes des conducteurs électriques raccordées aux éléments de connexion ou encore de modifier le positionnement des bornes de jonction.According to document EP-A-0 180 594, the mechanical resistance of the shielding box, during the overmolding operation of the insulating jacket, is solved by pressure-relief vents consisting of lids partially sheared in the bottom of the shells and remaining, when the molding pressure is admissible, in the same plane as this bottom (to oppose the intrusion of plastic material in the housing), but being susceptible when the pressure crosses a critical threshold to fade towards the interior of the housing, by articulation of the lids around the unsheared portions, in order to allow the extrusion of a quantity of material towards the interior of said housing. This design allows a pressure regulation effect but does not allow, on the other hand, the rigorous control of the mass of fluent material inside the housing which risks in case of high pressure to affect the electrical connections, in particular the insulating sheaths of the electrical conductors connected to the connection elements or even to modify the positioning of the junction terminals.

L'invention a pour but de palier les inconvénients rencontrés avec les matériels connus et concerne à cet effet un connecteur électrique du type constitué d'un bloc isolant, recevant des éléments de connexion, relié électriquement à un boîtier arrière, ledit bloc isolant étant protégé par deux demi-coquilles métalliques, susceptible d'être accouplées l'une à l'autre pour former un boîtier de blindage de haute résistance mécanique et de bonne continuité électrique avec le boîtier arrière de connexion, connecteur caractérisé en ce que les demi-coquilles du boîtier sont jumelles et comportent respectivement chacune un organe mâle et un organe femelle d'encliquetage, pour leur accouplement apparié, l'un des deux organes d'une même demi-coquille comprenant au moins une zone en partie élastiquement déformable, située en regard d'une ouverture pratiquée dans l'organe complémentaire de l'autre demi-coquille.The object of the invention is to overcome the drawbacks encountered with known equipment and for this purpose relates to an electrical connector of the type consisting of an insulating block, receiving connection elements, electrically connected to a rear housing, said insulating block being protected. by two metal half-shells, capable of being coupled to one another to form a shielding box of high mechanical strength and good electrical continuity with the rear connection box, connector characterized in that the half-shells of the housing are twin and have respectively each a male member and a female latching member, for their paired coupling, one of the two members of the same half-shell comprising at least one partially elastically deformable zone, situated opposite an opening made in the 'organ complementary to the other half-shell.

Suivant une caractéristique de l'invention, les demi-coquilles sont pourvues, au voisinage de leur bord libre avant, d'au moins une gorge coopérant avec un ou plusieurs tenons dépendant du boîtier arrière.According to a characteristic of the invention, the half-shells are provided, in the vicinity of their free front edge, with at least one groove cooperating with one or more tenons depending on the rear housing.

Selon un mode de réalisation préférentiel, l'organe femelle est constitué d'une languette flexible découpée dans la paroi latérale de la demi-coquille, et comporte un siège d'encliquetage avec l'organe mâle de la demi-coquille appariée, cette languette ayant la double fonction "d'accrochage" et "d'éventage".According to a preferred embodiment, the female member consists of a flexible tongue cut out from the side wall of the half-shell, and comprises a latching seat with the male member of the paired half-shell, this tongue having the double function of "hanging" and "venting".

Le siège d'encliquetage est avantageusement constitué d'un renfoncement oblong obtenu par emboutissage et repoussage du métal en direction de l'intérieur de la demi-coquille.The latching seat advantageously consists of an oblong recess obtained by stamping and pushing the metal in the direction of the interior of the half-shell.

Selon une caractéristique de l'invention l'organe mâle est constitué d'un téton d'encliquetage en saillie sur la face interne de la paroi latérale d'une demi-coquille, celui-ci étant positionné pour être, en position accouplée, en regard du renfoncement de la languette flexible de l'autre demi-coquille, une ouverture ménagée dans la paroi latérale de cette première demi-coquille, au droit du téton d'encliquetage, débouchant sur la languette flexible femelle de la seconde demi-coquille, de sorte qu'en cas de surpression, au moment de l'injection de l'enveloppe surmoulée, cette languette cède en s'effaçant vers l'intérieur du boîtier pour jouer le rôle de régulateur de pression en permettant à une quantité contrôlée de matière de fluer à l'intérieur du boîtier, sans nuire à la qualité des connexions électriques.According to a characteristic of the invention, the male member consists of a latching stud projecting from the internal face of the side wall of a half-shell, the latter being positioned to be, in the coupled position, in look of the recess of the flexible tongue of the other half-shell, an opening in the side wall of this first half-shell, in line with the latching stud, opening onto the flexible female tongue of the second half-shell, so that in the event of overpressure, at the time of injection of the overmolded envelope, this tab gives way, disappearing towards the inside of the housing to act as a pressure regulator by allowing a controlled amount of material to creep inside the housing, without affecting the quality of the electrical connections.

Selon une autre caractéristique préférentielle de l'invention, la continuité électrique entre le boîtier de blindage et le boîtier arrière de connexion est assurée par un contact direct et franc du bord libre avant des demi-coquilles avec la face arrière du boîtier, ce contact étant rendu positif par le verrouillage des tenons dudit boîtier arrière dans les gorges pratiquées sur ce bord avant.According to another preferred characteristic of the invention, the electrical continuity between the shielding box and the rear connection box is ensured by direct and frank contact of the free front edge of the half-shells with the rear face of the box, this contact being made positive by the locking of the pins of said rear housing in the grooves made on this front edge.

D'autres caractéristiques et avantages ressortiront de la description ci-après et des dessins annexés dans lesquels :

  • la figure 1 est une vue en coupe selon la ligne AA de la figure 2
  • la figure 2 est une vue en coupe suivant la ligne BB de la figure 1,
  • la figure 3 est une vue en coupe selon la ligne CC de la figure 1,
  • la figure 4 est une vue en coupe agrandie de la partie encerclée de la figure 2.
  • la figure 5 est une vue en coupe transversale suivant la ligne DD de la figure 1.
Other characteristics and advantages will emerge from the description below and the attached drawings in which:
  • Figure 1 is a sectional view along line AA of Figure 2
  • FIG. 2 is a sectional view along line BB of FIG. 1,
  • FIG. 3 is a sectional view along the line CC of FIG. 1,
  • FIG. 4 is an enlarged sectional view of the encircled part of FIG. 2.
  • FIG. 5 is a cross-sectional view along the line DD of FIG. 1.

Tel que représenté sur les figures de 1 à 5 le connecteur électrique de blindage est constitué de deux demi-coquilles métalliques 1,2 obtenues par découpage et emboutissage, celles-ci étant destinées à être appariées c'est-à-dire accouplées par paire pour former un corps creux de haute résistance mécanique et de bonne continuité électrique.As shown in Figures 1 to 5 the electrical shielding connector consists of two metal half-shells 1,2 obtained by cutting and stamping, these being intended to be paired, that is to say coupled in pairs to form a hollow body of high mechanical strength and good electrical continuity.

Les deux demi-coquilles présentent la particularité d'être symétriques, c'est-à-dire jumelles, et d'être de type hermaphrodite, chacune d'elle comportant au moins un organe mâle et un organe femelle de manière à ce que leur accouplement en position superposée amène respectivement en regard l'organe mâle d'une demi-coquille avec l'organe femelle de l'autre demi-coquille et inversement.The two half-shells have the particularity of being symmetrical, that is to say binoculars, and of being of the hermaphrodite type, each of them comprising at least one male organ and one female organ so that their coupling in the superimposed position brings respectively the male member of a half-shell opposite the female member of the other half-shell and vice versa.

La résistance mécanique du boîtier de blindage suppose d'une part que les deux demi-coquilles soient positivement verrouillées l'une à l'autre en position assemblée, d'autre part qu'il existe un régulateur de pression pour permettre une fuite contrôlée de la matière injectée constituant l'enveloppe surmoulée d'isolation, lorsque la pression d'injection franchit un seuil critique pouvant être de nature à déformer ou désaccoupler les deux demi-coquilles. Cette double fonction "d'accrochage" et "d'éventage" est réalisée concomittamment par les organes d'accouplement complémentaires des deux demi-coquilles.The mechanical resistance of the shielding box presupposes on the one hand that the two half-shells are positively locked to each other in the assembled position, on the other hand that there is a pressure regulator to allow a controlled leak of the injected material constituting the overmolded envelope of insulation, when the injection pressure crosses a critical threshold which may be of a nature to deform or uncoupling the two half-shells. This double function of "attachment" and "venting" is carried out simultaneously by the complementary coupling members of the two half-shells.

On décrira ci-après la constitution d'une demi-coquille sachant que l'autre est rigoureusement symétrique.We will describe below the constitution of a half-shell knowing that the other is rigorously symmetrical.

Chaque demi-coquille se présente sous la forme d'un flanc métallique 3 sensiblement plan, prolongé à l'arrière par deux plans inclinés 3₁, 3₂ convergeant l'un vers l'autre et se raccordant à une partie semi-circulaire 4 destinée à recevoir, après formation du boîtier de blindage, une ferrule de sertissage 5 renfermant le conducteur électrique. Ce flanc 3 est avantageusement rigidifié par des nervures 6, ici cruciformes, réalisées par emboutissage. Cette conception permet de répartir uniformément les pressions enregistrées par le boîtier de blindage.Each half-shell is in the form of a substantially flat metal sidewall 3, extended at the rear by two inclined planes 3₁, 3₂ converging towards one another and connecting to a semi-circular part 4 intended for receiving, after formation of the shielding box, a crimping ferrule 5 enclosing the electrical conductor. This sidewall 3 is advantageously stiffened by ribs 6, here cruciform, produced by stamping. This design allows the pressures recorded by the shielding unit to be distributed evenly.

Le flanc 3 est prolongé d'une jupe 7 (figure 5) orientée dans un plan sensiblement perpendiculaire audit flanc 3, ladite jupe bordant les deux côtés latéraux parallèles 7₁, et 7₂ (figure 1) ainsi que les bords inclinés 3₁ et 3₂ dudit flanc qui se raccorde à la partie semi-circulaire 4 de chaque demi-coquille.The sidewall 3 is extended by a skirt 7 (Figure 5) oriented in a plane substantially perpendicular to said sidewall 3, said skirt bordering the two parallel lateral sides 7₁, and 7₂ (Figure 1) as well as the inclined edges 3₁ and 3₂ of said sidewall which is connected to the semi-circular part 4 of each half-shell.

Comme visible en figure 5 le flanc de la demi-coquille se raccorde à sa jupe orthogonale 7 par un congé 8 et un décrochement 9. Les organes d'accouplement mâle et femelle de chaque demi-coquille sont constitués, comme illustré en figure 5, d'une languette 10 élastiquement déformable, constituant l'organe femelle, et d'un téton d'encliquetage 11 constituant l'organe mâle. La languette 10 est formée d'une patte en saillie découpée dans la jupe latérale de chaque demi-coquille, celle-ci comportant, comme visible sur la figure 3 qui est une coupe selon la ligne CC de la figure 1, un renfoncement ou"défoncé" 10₁ venu d'emboutissage et repoussage de la matière vers l'intérieur de la coquille. Cette cavité est de type oblong à fond plan dont le bord 10₂ est évasé vers l'extérieur et défini, dans la zone de raccordement de la languette 10 avec le fond de la demi-coquille, une zone d'articulation 10₃ favorisant, en cas de surpression (lors de l'injection de l'enveloppe isolante destinée à recouvrir intégralement le boîtier de blindage) le déclenchement instantané de la fonction "d'éventage" par basculement de la languette 10 vers l'intérieur du boîtier (comme illustré en trait mixte sur la figure 3), lorsque la pression de moulage dépasse un seuil admissible.As visible in Figure 5 the side of the half-shell is connected to its orthogonal skirt 7 by a fillet 8 and a recess 9. The organs male and female coupling of each half-shell consist, as illustrated in FIG. 5, of an elastically deformable tongue 10, constituting the female member, and of a latching stud 11 constituting the male member. The tongue 10 is formed by a projecting tab cut out from the side skirt of each half-shell, the latter comprising, as visible in FIG. 3 which is a section along the line CC in FIG. 1, a recess or ""10₁ from stamping and pushing the material towards the inside of the shell. This cavity is of oblong type with a flat bottom, the edge 10₂ of which is flared towards the outside and defined, in the zone of connection of the tongue 10 with the bottom of the half-shell, a zone of articulation 10₃ favoring, in the event overpressure (during the injection of the insulating envelope intended to completely cover the shielding box) the instantaneous triggering of the "venting" function by tilting the tongue 10 towards the inside of the box (as illustrated in line mixed in Figure 3), when the molding pressure exceeds an allowable threshold.

La cavité 10₁ de la languette déformable 10 sert également de moyen d'accrochage des deux demi-coquilles entre elles en servant de siège au téton d'encliquetage 11 constituant l'organe mâle qui vient par simple élasticité, lorsque les deux demi-coquilles sont assemblées l'une à l'autre, glisser sur la paroi latérale de la jupe de la demi-coquille opposée pour s'encliqueter positivement dans la cavité 10₁. Le téton d'encliquetage est avantageusement constitué d'un bossage de forme cônique à base ovoïde. Il est obtenu par repoussage de la matière en direction de l'intérieur du boîtier de blindage par un coup de pointeau.The cavity 10₁ of the deformable tongue 10 also serves as a means of hooking the two half-shells together, serving as a seat for the latching stud 11 constituting the male member which comes by simple elasticity, when the two half-shells are assembled to each other, slide on the side wall of the skirt of the opposite half-shell to snap positively into the cavity 10₁. The snap stud is advantageously made up of a conical boss with an ovoid base. It is obtained by pushing the material towards the interior of the shielding box by a punch.

La partie de la jupe comportant le téton d'encliquetage 11 est également pourvu d'une ouverture 12 jouant le rôle de régulateur de pression lors du surmoulage de l'enveloppe isolante, celle-ci, de forme sensiblement rectangulaire, étant pratiquée au droit du téton d'encliquetage pour venir, en position appariée des deux demi-coquilles, en regard de la cavité 10₁ de la languette souple 10 de l'autre demi-coquille. Cette ouverture est destinée à laisser librement passer la matière injectée vers l'intérieur du boîtier celle-ci pouvant ainsi librement fluer et se répandre dans la cavité 10₁ de la languette 10 lorque la pression de moulage ne dépasse pas un seuil critique. Dans cette éventualité la languette est normalement appliquée contre le téton d'encliquetage 11 et la matière est ainsi maîtrisée et localisée dans la cavité 10₁ de cette languette.The part of the skirt comprising the latching stud 11 is also provided with an opening 12 playing the role of pressure regulator during the overmolding of the insulating envelope, the latter, of substantially rectangular shape, being formed in line with the latching stud to come, in paired position of the two half-shells, opposite the cavity 10₁ of the flexible tab 10 of the other half-shell. This opening is intended to allow the material injected to pass freely towards the inside of the housing, the latter thus being able to freely creep and spread in the cavity 10₁ of the tongue 10 when the molding pressure does not exceed a critical threshold. In this event, the tongue is normally applied against the latching stud 11 and the material is thus controlled and located in the cavity 10₁ of this tongue.

Lorsque la pression devient inadmissible, c'est-à-dire lorsqu'elle est de nature à déformer le boîtier et à nuire aux connections électriques qu'il renferme, la déformabilité ou la résistance de la languette souple 10 est telle que celle-ci s'efface vers l'intérieur du boîtier en cédant autour de son point d'articulation 10₃ laissant ainsi une petite quantité de matière fluer à l'intérieur du boîtier afin de réguler la-pression de surmoulage. La quantité de matière se répandant à l'intérieur du boîtier est faible car s'agissant de petit matériel la masse de matière injectée pour former l'enveloppe isolante dans laquelle est noyé le boîtier de blindage est également réduite. En tout état de cause, cette fuite n'autorise que l'infiltration d'une petite quantité de matière qui ne peut pas nuire aux connections électriques, éloignées du lieu où se produit cette fuite ni au positionnement des bornes de jonction dont est pourvu le bloc isolant 13 (figure 2) enfermé dans le boîtier de blindage et raccordé au boîtier arrière de connection 14.When the pressure becomes inadmissible, that is to say when it is of a nature to deform the casing and to harm the electrical connections which it contains, the deformability or the resistance of the flexible tongue 10 is such that the latter disappears towards the inside of the case, yielding around its hinge point 10₃, thus leaving a small amount of material creeping inside the case in order to regulate the molding pressure. The amount of material spreading inside the housing is low because in the case of small equipment the mass of material injected to form the insulating envelope in which the shielding housing is embedded is also reduced. In any event, this leak only authorizes the infiltration of a small amount of material which cannot harm the electrical connections, far from the place where this leak occurs or the positioning of the junction terminals which are provided with the insulating block 13 (figure 2) enclosed in the housing shield and connected to the rear connection box 14.

Le plan de joint 15 des deux demi-coquilles n'est pas linéaire mais comprend un décrochement 15₁ pour la partie de la jupe comportant la languette élastique 10 formant l'organe femelle d'accouplement. A l'inverse l'autre demi-coquille 2 comporte un décrochement en saillie 15₂ au niveau de sa partie mâle, les deux demi-coquilles étant comme indiqué précédemment jumelles mais de conception hermaphrodite pour s'accoupler l'une à l'autre en position superposée.The joint plane 15 of the two half-shells is not linear but includes a step 15₁ for the part of the skirt comprising the elastic tongue 10 forming the female coupling member. Conversely, the other half-shell 2 has a projecting recess 15₂ at the level of its male part, the two half-shells being, as indicated above, twin but of hermaphrodite design for coupling to one another in superimposed position.

Les organes mâle et femelle qui viennent d'être décrits assurent la fonction "d'accrochage" et "d'éventage" au niveau de la partie arrière des deux demi-coquilles.The male and female members which have just been described ensure the "hooking" and "venting" function at the rear part of the two half-shells.

Le verrouillage s'effectue à l'avant par d'autres moyens qui assurent simultanément l'accouplement des deux demi-coquilles entre elles et leur jonction avec la face arrière 14₁ du boîtier de connexion 14 supportant le bloc isolant 13. On remarque ici que ce bloc isolant est largement en retrait des organes d'accouplement mâle et femelle assurant la fonction "d'accrochage" et "d'éventage" des deux demi-coquilles de sorte que la matière s'infiltrant à l'intérieur du boîtier de blindage, en cas de surpression a une certaine distance à parcourir avant d'arriver aux connexions électriques du boîtier arrière. L'accouplement des demi-coquilles 1 et 2 avec le boîtier arrière de connexion 14 est réalisé par la complémentarité de tenons ou griffes d'accrochage 16 attenant au boîtier arrière 14 et de gorges embouties sur chacun des deux flancs 3 des demi-coquilles.The locking is effected at the front by other means which simultaneously ensure the coupling of the two half-shells with one another and their junction with the rear face 14₁ of the connection box 14 supporting the insulating block 13. It is noted here that this insulating block is largely set back from the male and female coupling members ensuring the "hooking" and "venting" function of the two half-shells so that the material infiltrating inside the shielding box , in the event of overpressure a certain distance to travel before arriving at the electrical connections of the rear box. The coupling of the half-shells 1 and 2 with the rear connection box 14 is achieved by the complementarity of lugs or hooking claws 16 adjoining the rear box 14 and deep-drawn grooves on each of the two sides 3 of the half-shells.

Chaque gorge 17 s'étend le long du bord avant libre 18 de chaque demi-coquille celle-ci ayant un fond 17₁ (figure 4) semi-circulaire pour former un siège d'articulation permettant son pivotement autour des tenons de verrouillage 16 du boîtier arrière de connexion. Le débattement angulaire d'une demi-coquille est schématiquement représenté en traits mixtes sur la figure 4.Each groove 17 extends along the free front edge 18 of each half-shell, the latter having a semi-circular bottom 17₁ (FIG. 4) to form a seat. articulation allowing its pivoting around the locking pins 16 of the rear connection box. The angular displacement of a half-shell is schematically represented in dashed lines in FIG. 4.

Les tenons de verrouillage 16 du boîtier de connexion 14 se présentent sous la forme de deux pattes faisant saillie de chaque côté du boîtier de connexion (figure 2) celles-ci étant repliées vers l'intérieur et dépassant de la face avant 14₁ du boîtier arrière.The locking pins 16 of the connection box 14 are in the form of two tabs projecting on each side of the connection box (Figure 2) these being folded inwards and projecting from the front face 14₁ of the rear box .

Ces pattes assurent une jonction mécanique du boîtier de blindage et du boîtier arrière de connexion tout en parfaisant la continuité électrique des deux boîtiers.These tabs provide a mechanical junction of the shielding box and the rear connection box while perfecting the electrical continuity of the two boxes.

La mise en place c'est-à-dire aussi bien l'accouplement des deux demi-coquilles entre elles que leur jonction avec le boîtier arrière de connexion est réalisée comme illustré en figure 4. L'on introduit chacune des deux demi-coquilles en position inclinée pour amener son bord franc 18 à l'intérieur et sous les pattes de verrouillage 16 qui viennent alors se loger dans les gorges correspondantes 17. Dans cette position, on fait pivoter par simple articulation les deux demi-coquilles en direction l'une de l'autre jusqu'à ce que les tétons d'encliquetage 11 (formant l'organe mâle- de chaque demi-coquille) viennent se loger dans la cavité 10₁ de la languette élastique 10 (constituant l'organe femelle) de la coquille opposée. Ce simple encliquetage verrouille les deux demi-coquilles à leurs deux extrémités avant et arrière tout en assurant leur jonction avec le boîtier de connexion arrière 14. Il suffit ensuite de sertir la ferrule d'accouplement 5 sur le manchon circulaire formé par l'accouplement des deux portions semi-cyclindriques des deux demi-coquilles pour pouvoir ensuite procéder au surmoulage de l'enveloppe isolante destinée à protéger le connecteur électrique.The establishment, that is to say both the coupling of the two half-shells together and their junction with the rear connection box is carried out as illustrated in FIG. 4. Each of the two half-shells is introduced in the inclined position to bring its clear edge 18 inside and under the locking tabs 16 which are then housed in the corresponding grooves 17. In this position, the two half-shells are pivoted by simple articulation in the direction of the one from the other until the latching nipples 11 (forming the male member - of each half-shell) are housed in the cavity 10 lang of the elastic tongue 10 (constituting the female member) of the opposite shell. This simple snap locks the two half-shells at their two front and rear ends while ensuring their junction with the rear connection box 14. It then suffices to crimp the coupling ferrule 5 on the circular sleeve formed by the coupling of the two semi-cylindrical portions of the two half-shells so that we can then proceed when overmolding the insulating jacket intended to protect the electrical connector.

La conception de ce boîtier de blindage entraîne de multiples avantages tant du point de vue fabrication que du point de vue résistance et utilisation. D'une part, le fait que les deux demi-coquilles soient jumelles permet de ne faire appel qu'à un seul outil de découpe et d'emboutissage, ce qui réduit sensiblement les coûts de fabrication. D'autre part, la résistance mécanique obtenue à la fois par les nervures de rigidification du boîtier mais également et surtout par la fuite autorisée par les languettes flexibles constituant les organes femelles des deux demi-coquilles évite toute déformation ou destruction du blindage sans pour autant que cette décharge de pression soit de nature à endommager les connexions électriques logées à l'intérieur du boîtier de blindage. De même, la continuité électrique est simultanément assurée avec la jonction du boîtier de blindage et du boîtier de connexion arrière évitant ainsi tout champ parasite visible. Cette continuité électrique est favorisée par le bord avant droit et franc des coquilles en butée sur la face arrière du boîtier de connexion.The design of this shielding box brings with it multiple advantages both from the manufacturing point of view and from the resistance and use point of view. On the one hand, the fact that the two half-shells are twin means that only one cutting and stamping tool is used, which significantly reduces manufacturing costs. On the other hand, the mechanical resistance obtained both by the stiffening ribs of the housing but also and above all by the leakage authorized by the flexible tongues constituting the female members of the two half-shells avoids any deformation or destruction of the shielding without however this pressure discharge is likely to damage the electrical connections housed inside the shielding box. Similarly, electrical continuity is simultaneously ensured with the junction of the shielding box and the rear connection box, thus avoiding any visible interference field. This electrical continuity is favored by the straight and straight forward edge of the shells abutted on the rear face of the connection box.

Enfin, les demi-coquilles pourvues de languettes, nervures et gorges définissent, une fois assemblées, un volume fermé permettant une incrustation positive de la matière de surmoulage. Cette incrustation garantit l'accrochage de l'enveloppe et l'inviolabilité du connecteur.Finally, the half-shells provided with tongues, ribs and grooves define, once assembled, a closed volume allowing a positive inlay of the overmolding material. This inlay guarantees the attachment of the envelope and the inviolability of the connector.
