Description

Domaine techniqueTechnical area

La présente invention a pour objet un connecteur, notamment coudé, pour carte de circuit imprimé.The present invention relates to a connector, in particular angled, for a printed circuit board.

L'invention s'applique par exemple à un connecteur coaxial réalisé selon le schéma de normalisation FAKRA (Commission des normes de l'industrie automobile).The invention applies for example to a coaxial connector produced according to the FAKRA standardization scheme (Commission for Automotive Industry Standards).

Au sens de l'invention, on désigne par « connecteur coaxial selon le schéma de normalisation FAKRA », un connecteur coaxial comportant un corps dont les dimensions mécaniques dans une section axiale dudit corps coopérant avec le corps d'un connecteur complémentaire pour établir une liaison mécanique entre les deux corps sont définies dans la norme DIN 72594-1. De tels connecteurs sont généralement utilisés dans le domaine automobile pour les câbles de transmission de données.For the purposes of the invention, the term “coaxial connector according to the FAKRA standardization diagram” denotes a coaxial connector comprising a body whose mechanical dimensions in an axial section of said body cooperating with the body of a complementary connector to establish a connection. mechanics between the two bodies are defined in DIN 72594-1. Such connectors are generally used in the automotive field for data transmission cables.

L'invention peut également s'appliquer aux connecteurs pour circuits de transmission haut débit (LVDS).The invention can also be applied to connectors for high speed transmission circuits (LVDS).

De manière plus générale, l'invention peut s'appliquer à tout dispositif de connectique de transmission de signaux RF et de données (Datas) sur circuit imprimé.More generally, the invention can be applied to any connection device for transmitting RF signals and data (Datas) on a printed circuit.

Technique antérieurePrior art

On a représenté aux figures 1 à 6, un connecteur 10 déjà commercialisé, utilisé pour être monté sur une carte de circuit imprimé. Le connecteur obtenu peut être de type CMS (composant monté en surface), de type « pin in paste » (c'est-à-dire utilisant de la pâte à braser pour souder par surfusion des composants) ou encore de type « wave soldering » (soudure à la vague), selon par exemple le brevet US9004944B2 au nom de la demanderesse.We represented at figures 1 to 6 , a connector 10 already marketed, used to be mounted on a printed circuit board. The connector obtained can be of the CMS type (surface mounted component), of the “ pin in paste ” type (that is to say using solder paste for supercooling the components) or of the “ wave soldering ” type. " (Wave soldering), for example according to the patent US9004944B2 on behalf of the plaintiff.

Ce connecteur 10 est coudé et comporte un corps 2 et un boîtier 3 comportant un logement 6 dans lequel le corps est logé.This connector 10 is angled and comprises a body 2 and a housing 3 comprising a housing 6 in which the body is housed.

Le corps 2 est réalisé en métal, notamment en laiton ou en bronze, avantageusement selon la technologie dite « découpé-roulé », essentiellement pour des raisons de coût.The body 2 is made of metal, in particular of brass or bronze, advantageously according to the so-called “cut-roll” technology, essentially for reasons of cost.

Le corps 2 reçoit un isolant 7 à l'intérieur duquel plusieurs contacts centraux 8 sont disposés. Les contacts centraux 8 sont ici coudés, c'est-à-dire qu'ils s'étendent selon un axe longitudinal comportant deux portions 60 et 61 faisant un angle entre elles, qui est dans l'exemple décrit égal à 90°.The body 2 receives an insulator 7 inside which several central contacts 8 are arranged. The central contacts 8 are here angled, that is to say that they extend according to a longitudinal axis comprising two portions 60 and 61 forming an angle between them, which is in the example described equal to 90 °.

Le boîtier 3 s'étend dans cet exemple selon un axe longitudinal rectiligne X. Le boîtier 3 est par exemple réalisé en matière plastique, notamment en polyamide chargé de fibres de verre.The housing 3 extends in this example along a rectilinear longitudinal axis X. The housing 3 is for example made of plastic, in particular of polyamide filled with glass fibers.

Le boîtier 3 comporte une portion avant 11 présentant des reliefs permettant la connexion à un boîtier d'un connecteur complémentaire, une portion médiane 12 tubulaire dont le diamètre intérieur permet la réception du corps 2, et une portion arrière d'extrémité 13 autour de laquelle est disposée une armature 14.The housing 3 comprises a front portion 11 having reliefs allowing connection to a housing of a complementary connector, a tubular median portion 12 whose inside diameter allows the reception of the body 2, and a rear end portion 13 around which there is a frame 14.

Grâce à la présence de cette armature 14, la reprise d'efforts mécaniques avec la carte de circuit imprimé est effectuée par le boîtier 3 et l'armature 14. Ainsi, les efforts de traction sur le boîtier sont transmis à l'armature mais pas au corps du connecteur.Thanks to the presence of this armature 14, the absorption of mechanical forces with the printed circuit board is effected by the housing 3 and the armature 14. Thus, the tensile forces on the housing are transmitted to the armature but not to the connector body.

Comme représenté sur les figures 2 et 3, la portion arrière 13 du boîtier 3 peut présenter une forme de U en section transversale. Cette portion arrière 13 du boîtier reçoit une partie 5 du corps qui présente également une forme de U en section transversale, cette partie 5 comportant des retours 9 repliés contre un bord libre de la portion arrière 13 du boîtier, afin de maintenir le corps 2 en position dans le logement 6.As shown on figures 2 and 3 , the rear portion 13 of the housing 3 may have a U-shape in cross section. This rear portion 13 of the housing receives a part 5 of the body which also has a U-shape in cross section, this part 5 comprising returns 9 folded against a free edge of the rear portion 13 of the housing, in order to keep the body 2 in place. position in housing 6.

L'armature 14 est réalisée en métal, notamment en laiton ou bronze notamment en une seule pièce, en particulier grâce à la technologie du « découpé-roulé ». De la sorte, il est possible de réduire les coûts de fabrication des pièces malgré la faible épaisseur obtenue car la reprise se fait sur la totalité de l'armature.The frame 14 is made of metal, in particular of brass or bronze, in particular in one piece, in particular by virtue of the “cut-roll” technology. In this way, it is possible to reduce the manufacturing costs of the parts despite the small thickness obtained because the recovery is done over the entire reinforcement.

L'armature 14 présente en section perpendiculairement à l'axe X du boîtier 3 une forme de U, avec de préférence comme montré auxThe frame 14 has in section perpendicular to the X axis of the housing 3 a U-shape, preferably with, as shown in

Cette armature 14 comporte un dos 16 et deux ailes 17 reliées par le dos 16.This frame 14 has a back 16 and two wings 17 connected by the back 16.

L'armature 14 comporte également des pattes 18 permettant la fixation du connecteur 1 à une carte de circuit imprimé.The frame 14 also includes tabs 18 for fixing the connector 1 to a printed circuit board.

L'armature 14 comporte encore une portion 25 s'étendant sensiblement perpendiculairement à l'axe longitudinal X du boîtier 3 et fermant l'extrémité longitudinale 26 du boîtier 3 au niveau de sa portion arrière 13.The frame 14 also comprises a portion 25 extending substantially perpendicularly to the longitudinal axis X of the housing 3 and closing the longitudinal end 26 of the housing 3 at its rear portion 13.

Les ailes 17 et le dos 16 de l'armature 14 peuvent être reçus dans l'épaisseur de la portion arrière 13 du boîtier 3, c'est-à-dire dans des décrochements ménagés dans les ailes 17 et le dos 16 de l'armature 14. L'armature 14 peut être prise en sandwich entre des parois ou extrémités 26 du boîtier 3, comme montré en figure 3.The wings 17 and the back 16 of the frame 14 can be received in the thickness of the rear portion 13 of the housing 3, that is to say in recesses formed in the wings 17 and the back 16 of the frame 14. The frame 14 can be sandwiched between the walls or ends 26 of the housing 3, as shown in figure 3 .

Dans ce type de connecteur, pour des raisons de blindage électromagnétique et d'intégrité du signal, il est nécessaire que l'isolant 7 soit enveloppé d'une surface métallique sur le maximum de longueur de la ligne de transmission électrique.In this type of connector, for reasons of electromagnetic shielding and signal integrity, it is necessary for the insulator 7 to be enveloped in a metallic surface over the maximum length of the electrical transmission line.

En effet, si l'enveloppe métallique a des trous ou fentes, on risque des fuites de signal électrique, i.e. des fuites de signaux HF, qui détériorent la qualité du signal électrique.Indeed, if the metal casing has holes or slots, there is a risk of electrical signal leaks, i.e. HF signal leaks, which deteriorate the quality of the electrical signal.

Comme illustré en figure 3, le corps 2 enveloppe l'isolant 7 sur une grande partie de la ligne de transmission: les double-flèches illustrent en quelque sorte le confinement du signal électrique réalisé.As shown in figure 3 , the body 2 envelops the insulator 7 over a large part of the transmission line: the double arrows in a way illustrate the confinement of the electrical signal produced.

Cela étant, la réalisation du corps 2 en découpé-roulé, implique qu'il ne peut pas envelopper complètement l'isolant car, du fait des formes à plier, il est nécessaire de créer des fentes 200 pour avoir une épaisseur d'outil pour découper la pièce.However, the realization of the body 2 in cut-rolled, implies that it cannot completely envelop the insulation because, due to the shapes to be bent, it is necessary to create slots 200 to have a tool thickness for cut out the piece.

De plus, certaines formes ne peuvent se faire, car la matière que l'on voudrait ajouter créerait un chevauchement de surfaces qui rendrait la pièce irréalisable.In addition, some shapes cannot be made, because the material that we want to add would create an overlap of surfaces which would make the part impractical.

Ainsi, comme montré en figures 4 et 5A, le corps 2 est ouvert sur sa partie arrière.So, as shown in figures 4 and 5A , the body 2 is open on its rear part.

Une solution qui vient naturellement peut consister à réaliser une partie arrière du corps qui soit rabattable ou le rajout d'un capot métallique pour fermer la ligne de transmission électrique à l'arrière. Et la zone arrière pourrait être comblée par un isolant supplémentaire entre la partie rabattable du corps et le coude des contacts centraux.A solution which comes naturally may consist in making a rear part of the body which is foldable or the addition of a metal cover to close the electrical transmission line at the rear. And the rear area could be filled with additional insulation between the folding part of the body and the elbow of the central contacts.

Cette solution imposerait des dimensions différentes entre la ligne de transmission parallèle au circuit et la ligne de transmission perpendiculaire au circuit à l'arrière du connecteur, notamment entre le corps et les contacts centraux, et un éventuel isolant supplémentaire ajouté.This solution would impose different dimensions between the transmission line parallel to the circuit and the transmission line perpendicular to the circuit at the rear of the connector, in particular between the body and the central contacts, and any additional insulation added.

Cela aurait pour conséquence néfaste d'introduire une désadaptation d'impédance hyper-fréquence et de perturber fortement la qualité du signal.This would have the harmful consequence of introducing a hyper-frequency impedance mismatch and greatly disturbing the quality of the signal.

D'autre part, la zone arrière reste également ouverte. En effet, d'une part la fente 200 du corps conducteur 2 qui est prévue pour laisser passer l'outil de découpe est par définition dépourvue de matière. D'autre part, les ouvertures S1, S3, qui sont les surfaces d'isolant perpendiculaires à l'axe longitudinal X, sont d'autant plus importantes dans les versions de connecteurs coudés dont l'extrémité avant du boitier se positionne au-dessus du circuit imprimé, c'est-à-dire que la partie arrière perpendiculaire au circuit est d'autant plus longue (Figures 5A, 5B).On the other hand, the rear area also remains open. In fact, on the one hand, the slot 200 of the conductive body 2 which is provided to allow the cutting tool to pass is by definition devoid of material. On the other hand, the openings S1, S3, which are the insulation surfaces perpendicular to the longitudinal axis X, are all the more important in the versions of angled connectors whose front end of the box is positioned above. of printed circuit, that is to say that the rear part perpendicular to the circuit is all the longer ( Figures 5A, 5B ).

Il existe donc un besoin d'améliorer les connecteurs, en particulier coudés, destinés à une connexion à une carte de circuit imprimé, comprenant un corps métallique réalisé selon une technique découpé-roulé, notamment afin d'envelopper complètement l'isolant électrique logeant un ou plusieurs contacts centraux et un besoin d'améliorer ainsi le blindage électromagnétique et de supprimer ou à tout le moins réduire au maximum toute désadaptation d'impédance entre l'avant et l'arrière du connecteur.There is therefore a need to improve the connectors, in particular angled connectors, intended for connection to a printed circuit board, comprising a metal body produced using a cut-roll technique, in particular in order to completely envelop the electrical insulation housing a or more central contacts and a need thereby to improve the electromagnetic shielding and to eliminate or at least minimize any impedance mismatch between the front and the rear of the connector.

Le but de l'invention est de résoudre au moins partiellement ces besoins.The aim of the invention is to at least partially solve these needs.

Exposé de l'inventionDisclosure of the invention

Pour ce faire, l'invention a pour objet un connecteur, destiné à une connexion à une carte de circuit imprimé, le connecteur s'étendant selon un axe longitudinal (X) et comportant :

  • un corps électriquement conducteur,
  • au moins un contact logé au moins en partie dans le corps avec interposition d'un isolant électrique entre eux,
  • un boîtier définissant un logement configuré pour recevoir tout ou partie du corps, le boitier comprenant au moins une cavité,
  • un capot électriquement conducteur constitué d'au moins une pièce, inséré dans le corps électriquement conducteur, de sorte qu'au moins une de ses faces principales recouvre l'avant de l'isolant électrique, dans la partie arrière du logement de ce dernier à l'intérieur du corps électriquement conducteur qui est dénuée de paroi, le capot comprenant des portions en saillie au-dessus du corps et qui sont agencées dans la cavité du boitier, de sorte à former au moins deux points de blocage, dans les deux sens de la direction longitudinale (X), du capot conducteur dans le boitier.
To do this, the invention relates to a connector, intended for connection to a printed circuit board, the connector extending along a longitudinal axis (X) and comprising:
  • an electrically conductive body,
  • at least one contact housed at least partly in the body with the interposition of an electrical insulator between them,
  • a housing defining a housing configured to receive all or part of the body, the housing comprising at least one cavity,
  • an electrically conductive cover consisting of at least one part, inserted into the electrically conductive body, so that at least one of its main faces covers the front of the electrical insulator, in the rear part of the housing of the latter to the interior of the electrically conductive body which has no wall, the cover comprising projecting portions above the body and which are arranged in the cavity of the housing, so as to form at least two locking points, in both directions of the longitudinal direction (X), of the driver's cover in the box.

Le logement du boitier comprend une partie avant par laquelle la connexion à un connecteur complémentaire est destinée à être réalisée, et une partie arrière opposée à la partie avant,
De préférence, le corps conducteur est réalisé avec au moins une fente à l'avant de l'isolant électrique, ladite face principale du capot recouvrant ladite fente.The housing of the housing comprises a front part through which the connection to a complementary connector is intended to be made, and a rear part opposite the front part,
Preferably, the conductive body is made with at least one slot at the front of the electrical insulator, said main face of the cover covering said slot.

Selon un mode de réalisation avantageux, une autre des faces principales du capot recouvre l'arrière de l'isolant électrique.According to an advantageous embodiment, another of the main faces of the cover covers the rear of the electrical insulator.

De préférence, selon ce mode, le corps conducteur est réalisé avec au moins une fente, à l'arrière de l'isolant électrique, l'autre face principale du capot recouvrant ladite fente.Preferably, according to this embodiment, the conductive body is produced with at least one slot, at the rear of the electrical insulator, the other main face of the cover covering said slot.

Ainsi, l'invention consiste essentiellement en un capot conducteur que l'on vient monter en tant que composant supplémentaire dans un connecteur afin de former avec le corps conducteur, réalisé de préférence en découpé-roulé, une enveloppe métallique complète sur toute la ligne de transmission de signaux électriques transmis par le connecteur. Le capot conducteur est dimensionné avec des portions, qui une fois le capot monté, viennent en saillie dans au moins une cavité du boitier et agir comme points de blocage du boitier dans les deux sens de la direction longitudinale (X)Thus, the invention essentially consists of a conductive cover which is fitted as an additional component in a connector in order to form with the conductive body, preferably produced in cut-and-roll form, a complete metal casing over the entire line of transmission of electrical signals transmitted by the connector. The driver's cover is dimensioned with portions, which, once the cover is mounted, protrude into at least one cavity of the housing and act as blocking points of the housing in both directions of the longitudinal direction (X)

Grâce au capot selon l'invention, les ouvertures du corps ainsi que de préférence ses fentes, sont enveloppées, ce qui évite les fuites des signaux HF et la section d'isolant traversée par les signaux dans l'enveloppe métallique peut être la plus constante possible sur toute la longueur du connecteur, ce qui évite le risque de désadaptation d'impédance hyperfréquence.Thanks to the cover according to the invention, the openings of the body as well as preferably its slots, are enveloped, which prevents leakage of the HF signals and the section of insulation crossed by the signals in the metal envelope can be the most constant. possible over the entire length of the connector, which avoids the risk of microwave impedance mismatch.

Par conséquent, on obtient de manière simple et à moindre coût, avec un capot, de préférence constitué par une unique pièce, un connecteur qui peut transmettre les signaux RF de manière fiable.Therefore, with a cover, preferably consisting of a single piece, a connector which can transmit RF signals reliably is obtained in a simple and inexpensive manner.

Selon une variante de réalisation avantageux, le capot est constitué d'une seule pièce de forme générale rectangulaire, comprenant deux faces principales parallèles reliées par deux faces latérales. Avantageusement, la pièce est conformée de sorte que chaque face latérale relie les portions en saillie en formant un U. Une telle forme en U renforce encore la tenue/rétention mécanique du boitier.According to an advantageous variant embodiment, the cover consists of a single piece of generally rectangular shape, comprising two parallel main faces connected by two side faces. Advantageously, the part is shaped so that each side face connects the projecting portions by forming a U. Such a U-shape further strengthens the mechanical strength / retention of the case.

Avantageusement encore, les formes en U du capot conducteur sont agencées pour être positionnées à l'extérieur des parties latérales du corps conducteur. Cela permet de réaliser un ensemble multivoies, ensemble dit « duplex » avec un seul capot commun aux connecteurs comme détaillé par la suite.Again advantageously, the U-shaped shapes of the conductor cover are arranged to be positioned outside the lateral parts of the conductor body. This makes it possible to produce a multi-channel assembly, a so-called “duplex” assembly with a single cover common to the connectors as detailed below.

Selon un mode de réalisation avantageux, le connecteur est coudé avec le(s) contact(s) qui s'étend selon l'axe longitudinal (X) et qui comprend au moins une portion inclinée, étant notamment perpendiculaire, par rapport à un plan défini par une carte de circuit imprimé sur laquelle le connecteur est destiné à être connecté.According to an advantageous embodiment, the connector is bent with the contact (s) which extends along the longitudinal axis (X) and which comprises at least one inclined portion, being in particular perpendicular, relative to a plane defined by a printed circuit board on which the connector is intended to be connected.

Selon ce mode, l'isolant comprenant un coude, les faces principales du capot sont avantageusement perpendiculaires à la fois au plan et à la direction de connexion avec un connecteur complémentaire selon l'axe X, en recouvrant l'isolant électrique de part et d'autre de son coude.According to this embodiment, the insulation comprising an elbow, the main faces of the cover are advantageously perpendicular both to the plane and to the direction of connection with a complementary connector along the X axis, by covering the electrical insulation on both sides. other of his elbow.

Avantageusement, afin de garantir au mieux la continuité électrique de masse, le capot est inséré dans le corps avec contact physique entre eux.Advantageously, in order to best guarantee electrical ground continuity, the cover is inserted into the body with physical contact between them.

De préférence, l'une et/ou l'autre des faces principales du capot présente une forme extérieure adaptée pour épouser celle du corps. De préférence encore, l'une et/ou l'autre des faces principales du capot sont en contact avec appui-plan contre respectivement la face avant et la face arrière de l'isolant électrique, afin de garantir le positionnement mécanique de l'isolant et pour améliorer l'adaptation hyperfréquence.Preferably, one and / or the other of the main faces of the cover has an external shape adapted to match that of the body. More preferably, one and / or the other of the main faces of the cover are in contact with a support plane against the front face and the rear face of the electrical insulator respectively, in order to guarantee the mechanical positioning of the insulator. and to improve microwave adaptation.

Selon une variante de réalisation avantageuse, le capot, de préférence l'une et/ou l'autre de ses faces principales, comprend au moins un relief de destiné à harponner l'isolant, de sorte à bloquer ce dernier.According to an advantageous variant embodiment, the cover, preferably one and / or the other of its main faces, comprises at least one relief intended to harpoon the insulator, so as to block the latter.

Selon une variante de réalisation avantageuse, le capot, de préférence l'une et/ou l'autre de ses faces latérales reliant les faces principales, comprenant au moins un relief de rétention coopérant avec un relief complémentaire de rétention ménagé dans le boitier, de sorte à retenir le capot dans le boitier. Cette rétention peut se faire par harponnage ou clipsage et ainsi garantir une très bonne rétention mécanique du capot dans le boitier.According to an advantageous variant embodiment, the cover, preferably one and / or the other of its lateral faces connecting the main faces, comprising at least one retention relief cooperating with a complementary retention relief provided in the housing, of so as to retain the cover in the case. This retention can be done by harpooning or clipping and thus guarantee very good mechanical retention of the cover in the case.

Selon une variante de réalisation avantageuse, la face principale arrière du capot comprend au moins une languette de soutien coopérant avec une encoche ménagée dans le corps, de sorte à empêcher le fléchissement de ladite face arrière lors d'une poussée de l'isolant et/ou des contacts vers l'arrière du connecteur.According to an advantageous variant embodiment, the main rear face of the cover comprises at least one support tab cooperating with a notch formed in the body, so as to prevent the sagging of said rear face when the insulation is pushed and / or contacts towards the rear of the connector.

Avantageusement, le capot, de préférence l'une et/ou l'autre de ses faces principales, comprenant au moins une patte adaptée pour permettre la fixation du connecteur à une carte de circuit imprimé, de préférence par insertion et/ou soudure.Advantageously, the cover, preferably one and / or the other of its main faces, comprising at least one tab adapted to allow the connector to be attached to a printed circuit board, preferably by insertion and / or soldering.

Avantageusement, les portions faisant saillie au-dessus du corps dans la cavité du boitier, forment une butée mécanique lors d'un effort de traction exercé sur le boitier.Advantageously, the portions projecting above the body in the cavity of the housing form a mechanical stop during a tensile force exerted on the housing.

L'invention a également pour objet un ensemble de connexion multivoies, comportant au moins deux connecteurs tels que décrits précédemment, comprenant chacun un corps électriquement conducteur selon l'une quelconque des revendications précédentes agencés côte-à-côte, dans un boitier et, un capot réalisé en au moins une pièce, insérée dans les corps électriquement conducteurs, de sorte qu'au moins deux de ses faces principales recouvrent au moins partiellement les isolants électriques, dans les parties de leurs logements à l'intérieur des corps électriquement conducteurs qui sont dénuées de paroi.The subject of the invention is also a multi-way connection assembly, comprising at least two connectors as described above, each comprising an electrically conductive body according to any one of the preceding claims arranged side by side, in a housing and, a cover made of at least one piece, inserted in the electrically conductive bodies, so that at least two of its main faces at least partially cover the electrical insulators, in the parts of their housings inside the electrically conductive bodies which have no wall.

Selon une variante avantageuse, le capot est constitué d'une seule pièce de forme générale rectangulaire dont les deux faces principales parallèles sont reliées par deux faces latérales. Avantageusement, la pièce est conformée de sorte que chaque face latérale relie les portions en saillie en formant un U. Une telle forme en U renforce encore la tenue/rétention mécanique du boitier.According to an advantageous variant, the cover consists of a single piece of generally rectangular shape, the two parallel main faces of which are connected by two lateral faces. Advantageously, the part is shaped so that each side face connects the projecting portions by forming a U. Such a U-shape further strengthens the mechanical strength / retention of the case.

Description détailléedetailed description

Les figures 1 à 5B relatives à un connecteur coudé selon l'état de l'art ont été décrites dans le préambule. Elles ne seront donc pas commentées ci-après.The figures 1 to 5B relating to an elbow connector according to the state of the art have been described in the preamble. They will therefore not be commented on below.

Par souci de clarté, un même élément structurel d'un connecteur selon l'état de l'art et selon l'invention est désigné avec la même référence numérique.For the sake of clarity, the same structural element of a connector according to the state of the art and according to the invention is designated with the same reference number.

On précise ici dans l'ensemble de la présente demande, les termes « inférieur», « supérieur », « dessus », « dessous », « intérieur », « extérieur », « « interne », « externe» sont à comprendre par référence à un connecteur selon l'invention en configuration sensiblement à l'horizontal.It is specified here throughout the present application, the terms “lower”, “upper”, “above”, “below”, “inside”, “outside”, “inside”, “outside” are to be understood by reference to a connector according to the invention in a substantially horizontal configuration.

De même, les termes « avant » et arrière » sont à comprendre en référence à la face de connexion du connecteur, située à l'avant de celui-ci.Likewise, the terms “front” and rear ”should be understood with reference to the connection face of the connector, located at the front of the latter.

On a illustré aux figures 6 et 7, un connecteur coudé 1 selon l'invention s'étendant selon un axe longitudinal (X), destiné à assurer une connexion avec une carte de circuit imprimé (PCB).We have illustrated figures 6 and 7 , an elbow connector 1 according to the invention extending along a longitudinal axis (X), intended to provide a connection with a printed circuit board (PCB).

Le connecteur coudé 1 comporte un corps électriquement conducteur 2, des contacts centraux 8 logés au moins en partie dans le corps 2 avec interposition d'un isolant électrique 7.The elbow connector 1 comprises an electrically conductive body 2, central contacts 8 housed at least partly in the body 2 with the interposition of an electrical insulator 7.

Un boîtier isolant électrique 3, définissant un logement, loge tout ou partie du corps 2.An electrically insulating box 3, defining a housing, accommodates all or part of the body 2.

Le corps 2 comprend avantageusement des languettes d'appui 29 adaptées pour venir s'appuyer contre le PCB.The body 2 advantageously comprises support tongues 29 adapted to come to rest against the PCB.

Selon l'invention, il est prévu un capot électriquement conducteur 10 constitué dans l'exemple décrit d'une seule pièce, inséré dans le corps électriquement conducteur 2.According to the invention, there is provided an electrically conductive cover 10 formed in the example described as a single piece, inserted into the electrically conductive body 2.

Ce capot conducteur 10 est de préférence réalisé par une technique de découpé-roulé, à l'instar du corps conducteur 2.This conductive cover 10 is preferably produced by a cut-and-roll technique, like the conductive body 2.

Tel qu'illustré en figure 11, le capot conducteur 10 a une forme générale rectangulaire et comprend ainsi deux flans formant les faces principales 100, 101 parallèles reliées entre elles par des faces latérales 102, 103.As illustrated in figure 11 , the conductive cover 10 has a generally rectangular shape and thus comprises two blanks forming the main faces 100, 101 parallel connected to one another by side faces 102, 103.

Les dimensions des différentes faces 100 à 103 ainsi que leurs contours sont définis pour que les faces principale 100, 101 recouvrent au moins partiellement l'isolant électrique 7, dans la partie de son logement à l'intérieur du corps conducteur 10 qui est dénuée de paroi. Cela permet d'obstruer les ouvertures du corps 2 et donc de supprimer les risques de fuites de signaux HF.The dimensions of the various faces 100 to 103 as well as their contours are defined so that the main faces 100, 101 at least partially cover the electrical insulator 7, in the part of its housing inside the conductive body 10 which is devoid of wall. This makes it possible to obstruct the openings of the body 2 and therefore to eliminate the risk of HF signal leaks.

De plus, l'écran aux interférences électromagnétiques (EMI acronyme anglo-saxon pour « Electromagnetic Interference »), formé par le capot conducteur 10 est avantageusement complété par l'appui des languettes 29 du corps 2 sur le PCB.In addition, the screen against electromagnetic interference (EMI acronym for “Electromagnetic Interference”), formed by the conductive cover 10 is advantageously completed by pressing the tabs 29 of the body 2 on the PCB.

D'autre part, le capot conducteur 10 est positionné au plus près de l'isolant 7 grâce aux fentes 200 et 201 du corps. Autrement dit, les faces principales 100 et 101 du capot conducteur 10 viennent parfaitement s'insérer dans les fentes 200, 201 tout en recouvrant les faces avant et arrière de l'isolant électrique 7.On the other hand, the conductive cover 10 is positioned as close as possible to the insulation 7 thanks to the slots 200 and 201 in the body. In other words, the main faces 100 and 101 of the conductive cover 10 fit perfectly into the slots 200, 201 while covering the front and rear faces of the electrical insulator 7.

Cela permet de garder une section d'isolant la plus constante possible entre la partie de connexion avec la carte de circuit imprimé, sur le dessous du connecteur coudé, et la partie de connexion avec un connecteur complémentaire et donc d'améliorer l'homogénéité de la propagation du signal.This makes it possible to keep an insulation section as constant as possible between the connection part with the printed circuit board, on the underside of the elbow connector, and the connection part with a complementary connector and therefore to improve the homogeneity of signal propagation.

Cela est bien illustré en figure 9, où l'on voit que la ligne de transmission d'un signal HF à l'intérieur du connecteur 1 selon l'invention, symbolisé par le cheminement des double-flèches est parfaitement guidé et contenu entre le corps conducteur 2 et les faces principales 100, 101 du capot conducteur 10 avec des dimensions similaires.This is well illustrated in figure 9 , where we see that the transmission line of an HF signal inside the connector 1 according to the invention, symbolized by the path of the double arrows is perfectly guided and contained between the conductive body 2 and the main faces 100, 101 of the conductor cover 10 with similar dimensions.

Autrement dit, le capot conducteur 10 forme avec le corps conducteur 2 une enveloppe métallique sur toute la ligne de transmission des signaux HF à l'intérieur du connecteur coudé 1. L'adaptation d'impédance de la ligne hyperfréquence est ainsi améliorée.In other words, the conductive cover 10 forms with the conductive body 2 a metal casing over the entire transmission line of the HF signals inside the elbow connector 1. The impedance matching of the microwave line is thus improved.

Également, l'écartement entre les différentes faces 100 à 103 du capot conducteur 10 et l'emplacement des fentes 200, 201 du corps conducteur 2 dans lesquelles viennent s'insérer les faces principales 100, 101 du capot 10 permet de garder une section d'isolant la plus constante possible entre la partie de connexion avec la carte de circuit imprimé, sur le dessous du connecteur coudé, et la partie de connexion avec un connecteur complémentaire. De préférence, les faces principales 100, 101 du capot 10 sont en contact avec appui-plan contre respectivement les faces avant et arrière de l'isolant électrique 7, afin de garantir le positionnement mécanique de l'isolant et pour améliorer l'adaptation hyperfréquence.Also, the spacing between the different faces 100 to 103 of the conductor cover 10 and the location of the slots 200, 201 of the conductive body 2 into which the main faces 100, 101 of the cover 10 are inserted makes it possible to keep a section d. 'insulation as constant as possible between the connection part with the printed circuit board, on the underside of the elbow connector, and the connection part with a complementary connector. Preferably, the main faces 100, 101 of the cover 10 are in contact with a plane support against the front and rear faces of the electrical insulator 7, respectively, in order to guarantee the mechanical positioning of the insulator and to improve the microwave adaptation. .

Cela est symbolisé en figure 13 par l'encadré en pointillés noir qui délimite une section S4 d'isolant 7 dans laquelle les signaux HF sont transmis, qui est constante depuis la partie de connexion dessous du connecteur 1 jusqu'à sa face avant de connexion.This is symbolized in figure 13 by the black dotted box which delimits a section S4 of insulation 7 in which the HF signals are transmitted, which is constant from the connection part below the connector 1 to its front connection face.

De préférence, comme clairement illustré en figure 8, le capot 10 est en contact physique avec le corps 2 pour avoir une continuité de masse.Preferably, as clearly illustrated in figure 8 , the cover 10 is in physical contact with the body 2 in order to have earth continuity.

Le capot conducteur 10 peut avantageusement comprendre un ou plusieurs reliefs de rétention 104, par exemple un par face latérale 102, 103, qui permet de réaliser la rétention du capot 10 dans le boitier 3 (figure 8). Ainsi, en cas d'effort d'arrachement du boitier 3 selon une direction orthogonale à la direction X, ce dernier est retenu fortement par des reliefs de rétention. Plus particulièrement lorsque le connecteur est fixé au PCB par le biais des pattes de fixation 18, les reliefs de rétention 104 qui sont maintenus par encliquetage à l'intérieur de reliefs complémentaires dans le boitier 3 permettent de retenir mécaniquement ce dernier en cas d'effort d'arrachement du PCB, c'est-à-dire un effort de traction pour éloigner le connecteur du PCB.The conductor cover 10 can advantageously comprise one or more retention reliefs 104, for example one per side face 102, 103, which enables the retention of the cover 10 in the housing 3 ( figure 8 ). Thus, in the event of an effort to tear off the housing 3 in a direction orthogonal to the X direction, the latter is strongly retained by retention reliefs. More particularly when the connector is fixed to the PCB by means of the fixing lugs 18, the retention reliefs 104 which are held by snap-fastening inside complementary reliefs in the housing 3 make it possible to mechanically retain the latter in the event of a force. pulling the PCB, that is to say a pulling force to move the connector away from the PCB.

En outre, le capot conducteur 10 peut avantageusement comprendre un ou plusieurs reliefs de blocage 105, par exemple un sur la face principale avant 100, afin de bloquer ce dernier sur le capot 10 (figures 7, 8).In addition, the driver cover 10 can advantageously comprise one or more blocking reliefs 105, for example one on the main front face 100, in order to block the latter on the cover 10 ( figures 7 , 8 ).

Par ailleurs, on peut prévoir avantageusement de munir la face principale arrière 101 du capot 10 d'une languette 106 qui s'insère à l'intérieur d'une fente 202 prévue à cet effet à l'arrière du corps 2 (figure 12). Ainsi insérée, cette languette 106 permet d'empêcher le fléchissement de la face principale arrière 101, lorsqu'un utilisateur vient pousser l'isolant 7 et les contacts centraux 8 vers l'arrière. Autrement dit, cette languette 106 permet une reprise de forces supplémentaire.Furthermore, provision can advantageously be made to provide the rear main face 101 of the cover 10 with a tongue 106 which fits inside a slot 202 provided for this purpose at the rear of the body 2 ( figure 12 ). Thus inserted, this tongue 106 makes it possible to prevent the rear main face 101 from sagging when a user pushes the insulator 7 and the central contacts 8 rearward. In other words, this tongue 106 allows additional force absorption.

Enfin, le capot conducteur 10 peut être muni de pattes 18 de fixation à une carte de circuit imprimé (PCB). Comme illustré, on peut prévoir des pattes de fixation 18 qui peuvent être insérées directement dans le PCB avant d'y être soudées,Finally, the conductive cover 10 can be provided with tabs 18 for fixing to a printed circuit board (PCB). As illustrated, it is possible to provide fixing lugs 18 which can be inserted directly into the PCB before being soldered therein,

Dans les exemples illustrés, les pattes de fixation longues 18 sont de préférence réalisées en extrémité inférieure de la face principale avant 100 du capot 10, tandis que des pattes courtes 19, pour la reprise de masse électrique, sont réalisées en extrémité inférieure de la face principale arrière 101 du capot 10.In the examples illustrated, the long fixing lugs 18 are preferably made at the lower end of the main front face 100 of the cover 10, while the short lugs 19, for the electrical earth connection, are made at the lower end of the face. main rear 101 of the cover 10.

Le corps conducteur 2 peut également être muni de pattes de fixation 18, qui participent avec les pattes de fixation 18 du capot 10, à la fixation complète du connecteur coudé 1 sur un PCB.The conductive body 2 can also be provided with fixing lugs 18, which participate with the fixing lugs 18 of the cover 10, in the complete fixing of the elbow connector 1 on a PCB.

Avantageusement, on peut dimensionner le capot 10 de sorte qu'une fois monté, et de préférence retenu dans le boitier 3, il présente des portions 1000, 1001 qui dépassent au-dessus du corps 2 en étant agencées dans une cavité 30 du boitier 3 (figures 8, 9, 14, 18 à 22). Cet agencement en saillie selon une hauteur e de ces portions 1000, 1001 permet de garantir une tenue mécanique du boitier 3 sur le corps 2. Ainsi, lorsqu'un effort de traction du boitier 3, comme symbolisé par la double-flèche T en figures 13 et 14, c'est-à-dire selon une direction parallèle au plan d'un PCB sur lequel le connecteur est fixé, le capot 10 agit comme une butée mécanique du boitier 3. Autrement dit, ces portions 1000, 1001 forment au moins deux points de blocage distants, de préférence quatre points de blocage du capot conducteur 10 dans le boitier 3.Advantageously, the cover 10 can be dimensioned so that once mounted, and preferably retained in the housing 3, it has portions 1000, 1001 which protrude above the body 2 by being arranged in a cavity 30 of the housing 3. ( figures 8, 9 , 14 , 18 to 22 ). This projecting arrangement at a height e of these portions 1000, 1001 makes it possible to guarantee a mechanical strength of the box 3 on the body 2. Thus, when a tensile force of the box 3, as symbolized by the double arrow T in figures 13 and 14 , that is to say according to a direction parallel to the plane of a PCB on which the connector is fixed, the cover 10 acts as a mechanical stop for the housing 3. In other words, these portions 1000, 1001 form at least two remote locking points, preferably four locking points. blocking of the driver's cover 10 in the unit 3.

Comme cela est visible sur l'ensemble des figures 6 à 14, le corps conducteur 2 et le boitier 3 sont dimensionnés pour créer un volume de matière à l'arrière de l'isolant électrique 3 qui permet de bien positionner le centre de gravité du connecteur, afin qu'il ait une meilleure stabilité lorsqu'il est en appui contre un circuit imprimé PCB. En outre, le corps 2 allongé à l'arrière de l'isolant 7 permet de lui conférer des pattes arrières de fixation 18 au PCB par soudure qui sont éloignées des pattes 18 à l'avant, ce qui participe également à une meilleure fixation.As can be seen on all figures 6 to 14 , the conductive body 2 and the housing 3 are sized to create a volume of material behind the electrical insulator 3 which allows the center of gravity of the connector to be correctly positioned, so that it has better stability when is resting against a printed circuit PCB. In addition, the elongated body 2 at the rear of the insulator 7 enables it to be given rear fixing lugs 18 to the PCB by soldering which are remote from the lugs 18 at the front, which also contributes to better fixing.

On décrit maintenant en référence aux figures 15A à 15E, les différentes étapes d'assemblage d'un connecteur coudé 1 selon l'invention. Dans ces différentes figures, le sens de montage d'un composant dans l'autre est indiqué par une flèche.We now describe with reference to figures 15A to 15E , the various stages of assembly of an elbow connector 1 according to the invention. In these various figures, the direction of assembly from one component to the other is indicated by an arrow.

Au préalable, on dispose de l'ensemble des composants essentiels à l'assemblage, à savoir le corps conducteur 2, le boitier 3, l'isolant électrique 7, les contacts centraux 8 ainsi que le capot conducteur 10 conforme à l'invention (figure 15A).

  • Etape a/: On réalise le montage des contacts centraux 8 par insertion dans l'isolant 7 (figure 15A). On peut envisager en lieu et place un surmoulage des contacts centraux 8 par une matière isolante électrique formant, au final, l'isolant 7 autour des contacts centraux 8.
  • Etape b/: On réalise le montage du premier sous-ensemble ainsi formé de l'isolant 7 logeant les contacts centraux 8 dans le corps conducteur 2 (figure 15B).
  • Etape c/: On réalise le montage du deuxième sous-ensemble ainsi formé de l'isolant 7 avec le corps conducteur 2 et les contacts centraux 8 dans le boitier 3 (figure 15C).
  • Etape d/: On réalise alors le montage par le dessous du capot conducteur 10, de sorte à ce que ses faces principales 100, 101 s'insèrent dans les fentes correspondantes 200, 201 du capot conducteur 2 (figure 15D).
Beforehand, all the components essential to the assembly are available, namely the conductive body 2, the housing 3, the electrical insulator 7, the central contacts 8 as well as the conductive cover 10 according to the invention ( figure 15A ).
  • Step a / : The central contacts 8 are assembled by insertion in the insulator 7 ( figure 15A ). One can consider instead an overmolding of the central contacts 8 by an electrical insulating material forming, in the end, the insulation 7 around the central contacts 8.
  • Step b / : The first sub-assembly thus formed of the insulator 7 housing the central contacts 8 in the conductive body 2 ( figure 15B ).
  • Step c / : The second sub-assembly thus formed of the insulator 7 is assembled with the conductive body 2 and the central contacts 8 in the housing 3 ( figure 15C ).
  • Step d / : The assembly is then carried out from below the conductor cover 10, so that its main faces 100, 101 fit into the corresponding slots 200, 201 of the conductor cover 2 ( figure 15D ).

Autrement dit, les faces principales 100, 101 sont glissées dans les fentes 200, 201 depuis le dessous du corps 2 et ce de préférence jusqu'à buter sur le corps 2.In other words, the main faces 100, 101 are slid into the slots 200, 201 from the underside of the body 2 and this preferably until they come up against the body 2.

Cette étape d/ est de préférence réalisée jusqu'à mise en butée du capot 10 sur le corps 2.This step d / is preferably carried out until the cap 10 comes into abutment on the body 2.

De préférence également, le montage du capot 10 est réalisé avec blocage de chaque relief en saillie 105 dans la gorge correspondante 70 de l'isolant 7 et jusqu'à la rétention par harponnage ou clipsage du capot 10 dans le boitier 3 par le biais de chaque relief en saillie 104 qui vient s'harponner ou se clipser à l'intérieur du relief complémentaire ménagé à cet effet à l'intérieur du boitier 3.Also preferably, the cover 10 is fitted with blocking of each protruding relief 105 in the corresponding groove 70 of the insulator 7 and until the cover 10 is retained by spear or clipping in the housing 3 by means of each protruding relief 104 which is hooked or clipped inside the complementary relief provided for this purpose inside the case 3.

Cette étape d/ est réalisée avec logement des portions 1000, 1001 dans la cavité 30 du boitier 3 de sorte que le capot 10 forme une butée mécanique au boitier 30 avec les portions 1000, 1001 qui agissent comme des points de blocage dans les deux sens de la direction longitudinale (X), du capot conducteur 10 dans le boitier 3.This step d / is carried out with the housing of the portions 1000, 1001 in the cavity 30 of the housing 3 so that the cover 10 forms a mechanical stop on the housing 30 with the portions 1000, 1001 which act as locking points in both directions. of the longitudinal direction (X), of the driver cover 10 in the box 3.

Etape e/: Une fois le montage du capot conducteur 10, et de préférence sa retenue dans le boitier 3 effectuée, le connecteur coudé selon l'invention est prêt à être utilisé (figure 15E). Step e / : Once the conductor cover 10 has been fitted, and preferably retained in the housing 3, the elbow connector according to the invention is ready to be used ( figure 15E ).

On va maintenant décrire en référence aux figures 16 à 19 un ensemble de connexion 4 comportant deux connecteurs coudés 1.1, 1.2 selon l'invention, agencés côte-à-côte, appelé généralement duplex.We will now describe with reference to figures 16 to 19 a connection assembly 4 comprising two elbow connectors 1.1, 1.2 according to the invention, arranged side by side, generally called duplex.

Dans cet exemple illustré, l'ensemble 4 comprend un seul boitier 3 réalisé d'une seule pièce, formant un boîtier commun aux deux connecteurs 1.1, 1.2 et dans lequel deux logements traversants sont ménagés, chacun de ces logements traversants recevant un des deux connecteurs 1.1, 1.2.In this illustrated example, the assembly 4 comprises a single housing 3 made in a single piece, forming a housing common to the two connectors 1.1, 1.2 and in which two through housings are provided, each of these through housing receiving one of the two connectors 1.1, 1.2.

Également, l'ensemble de connexion 4 comprend un seul capot conducteur 10 avec des pattes de fixation 18, réalisé d'une seule pièce, qui est commun aux deux connecteurs 1.1, 1.2.Also, the connection assembly 4 comprises a single conductor cover 10 with fixing lugs 18, made in one piece, which is common to the two connectors 1.1, 1.2.

Chacun des connecteurs 1.1, 1.2 comporte un corps conducteur 2.1, 2.2 avec des pattes de fixation 18.1, 18.2, un isolant 7.1, 7.2 et des contacts centraux 8.1, 8.2 qui lui sont propres et similaires à ceux déjà décrits en référence aux figures 6 à 15E.Each of the connectors 1.1, 1.2 comprises a conductive body 2.1, 2.2 with fixing lugs 18.1, 18.2, an insulator 7.1, 7.2 and central contacts 8.1, 8.2 which are specific to it and similar to those already described with reference to figures 6 to 15E .

Également, le capot commun 10 comporte des reliefs de blocage de l'isolant 105.1, 105.2 ainsi que des languettes de soutien 106.1, 106.2 qui sont distinctes pour chaque connecteur 1.1, 1.2 et similaires à ceux déjà décrits en référence aux figures 6 à 15E.Also, the common cover 10 comprises blocking reliefs for the insulation 105.1, 105.2 as well as support tabs 106.1, 106.2 which are separate for each connector 1.1, 1.2 and similar to those already described with reference to figures 6 to 15E .

En revanche, le capot commun 10 comprend des portions de blocage 1000, 1001 dans le boitier 3 ainsi que des reliefs de rétention 104 au boitier 3 qui sont communs aux deux connecteurs 1.1, 1.2 et similaires à ceux déjà décrits en référence aux figures 6 à 15E.On the other hand, the common cover 10 comprises locking portions 1000, 1001 in the housing 3 as well as retention reliefs 104 in the housing 3 which are common to the two connectors 1.1, 1.2 and similar to those already described with reference to figures 6 to 15E .

Dans l'ensemble des figures 6 à 15E, le capot conducteur 10 selon l'invention est réalisé en une seule pièce.Overall figures 6 to 15E , the conductive cover 10 according to the invention is made in one piece.

Les figures 20 à 22 montrent un autre mode de réalisation selon lequel le capot conducteur 10 est réalisé en deux pièces distinctes 100, 101. Comme montré sur ces figures, ces deux pièces 100, 101 peuvent reprendre exactement les mêmes formes que les deux faces principales avant et arrière 100, 101 du capot 10 lorsqu'il est réalisé avec une seule pièce, c'est-à-dire avec des faces latérales 102, 103 qui rejoignent les deux faces principales.The figures 20 to 22 show another embodiment according to which the conductive cover 10 is made in two separate parts 100, 101. As shown in these figures, these two parts 100, 101 can take exactly the same shapes as the two main front and rear faces 100, 101 of the cover 10 when it is made with a single piece, that is to say with side faces 102, 103 which join the two main faces.

Ainsi, dans le mode de réalisation des figures 20 à 22, les deux pièces 100, 101 planes peuvent chacune s'insérer respectivement dans la fente 200, 201 d'un corps conducteur 2.Thus, in the embodiment of figures 20 to 22 , the two flat parts 100, 101 can each be inserted respectively into the slot 200, 201 of a conductive body 2.

D'autres variantes et avantages de l'invention peuvent être réalisés sans pour autant sortir du cadre de l'invention.Other variants and advantages of the invention can be achieved without departing from the scope of the invention.

Par exemple, si l'ensemble des exemples illustrés, les connecteurs équipés d'un capot conducteur selon l'invention sont des connecteurs coudés, l'invention s'applique également à tous connecteurs droits que l'on peut équiper d'un capot conducteur.For example, if all of the examples illustrated, the connectors fitted with a conductive cover according to the invention are angled connectors, the invention also applies to all straight connectors that can be fitted with a conductive cover. .

De même, le capot conducteur 10 peut être réalisé en une seule ou plusieurs pièces selon différentes formes. Ainsi, outre un mode de réalisation en une seule pièce avec des faces principales avant et arrière 100, 101 (figures 6 à 15E), et un mode de réalisation à deux pièces planes 100, 101 (figures 20, 22), on peut encore envisager de réaliser le capot conducteur 10 selon l'invention, en deux pièces en forme générale de L, en vue de côté, par exemple une pièce en L qui serait constituée par la face principale 100 et la face latérale 102, tandis que l'autre pièce en L serait constituée par la face principale 101 et la face latérale 103.Likewise, the conductive cover 10 can be made in one or more parts in different shapes. Thus, in addition to a one-piece embodiment with main front and rear faces 100, 101 ( figures 6 to 15E ), and an embodiment with two flat pieces 100, 101 ( figures 20 , 22 ), it is also possible to envisage producing the conductor cover 10 according to the invention in two parts in the general shape of an L, in side view, for example an L-shaped part which would be constituted by the main face 100 and the side face 102 , while the other L-shaped part would consist of the main face 101 and the side face 103.

L'invention n'est pas limitée aux exemples qui viennent d'être décrits ; on peut notamment combiner entre elles des caractéristiques des exemples illustrés au sein de variantes non illustrées.The invention is not limited to the examples which have just been described; characteristics of the examples illustrated can in particular be combined with one another within variants not illustrated.
