Description

La présente invention concerne un élément coudé de connecteur coaxial apte à être fixé à une carte imprimée.The present invention relates to a bent coaxial connector element capable of being fixed to a printed circuit board.

On connaît déjà des connecteurs coaxiaux permettant de relier électriquement deux cartes imprimées disposées perpendiculairement l'une par rapport à l'autre.Coaxial connectors are already known which make it possible to electrically connect two printed boards arranged perpendicularly to one another.

La demanderesse a déjà décrit un tel connecteur coaxial dans FR-A-2.685.553.The Applicant has already described such a coaxial connector in FR-A-2,685,553.

Ce connecteur comporte un élément droit ainsi qu'un élément coudé, lequel est muni, sur l'une de ses faces, de broches pour son raccordement à une première carte imprimée et, sur une face perpendiculaire à la première, de contacts coaxiaux aptes à coopérer avec des contacts coaxiaux de l'élément droit qui est raccordé à une seconde carte imprimée disposée perpendiculairement à la première carte imprimée.This connector comprises a straight element as well as a bent element, which is provided, on one of its faces, with pins for its connection to a first printed circuit board and, on a face perpendicular to the first, of coaxial contacts suitable for cooperate with coaxial contacts of the straight element which is connected to a second printed card arranged perpendicular to the first printed card.

L'élément coudé est en général raccordé à la première carte imprimée par enfichage et soudure à l'étain-plomb de ses broches dans des orifices correspondants réalisés sur ladite carte.The bent element is generally connected to the first printed card by plugging and soldering with tin-lead of its pins in corresponding orifices made on said card.

Dans certains cas, l'élément coudé comporte, en tant que broches, des contacts insérables à force.In certain cases, the bent element has, as pins, force-insertable contacts.

Ces contacts comportent une partie centrale élastique qui présente une section extérieure supérieure à la section de passage des orifices prévus sur la carte.These contacts comprise an elastic central part which has an outer section greater than the section for passage of the orifices provided on the card.

Le montage sur la carte imprimée d'un élément de connecteur muni de contacts insérables à force s'effectue en exerçant une force importante (de l'ordre de 30 à 100 Newtons) par contact sur sa face opposée à la carte, de manière à forcer les contacts à l'intérieur des orifices.The mounting on the printed card of a connector element provided with force-insertable contacts is carried out by exerting a significant force (of the order of 30 to 100 Newtons) by contact on its face opposite to the card, so force the contacts inside the holes.

Une fois fixé à la carte imprimée, l'élément de connecteur présente une bonne tenue mécanique.Once attached to the circuit board, the connector element exhibits good mechanical strength.

On constate cependant dans la pratique une insuffisance au niveau des propriétés de transmission électrique, due à une certaine désadaptation d'impédance.However, in practice there is an insufficiency in the electrical transmission properties, due to a certain mismatch of impedance.

La présente invention vise à fournir un élément coudé de connecteur coaxial évitant notamment cet inconvénient.The present invention aims to provide a bent element of coaxial connector avoiding in particular this drawback.

La présente invention a pour objet un élément coudé de connecteur coaxial du type comportant un corps conducteur sensiblement parallélépipédique, au moins une tige conductrice coudée dont une extrémité est reliée à une broche en saillie de l'une des faces dudit corps et dont l'autre extrémité est reliée au conducteur central d'un contact coaxial, en saillie d'une autre face dudit corps et perpendiculaire à la broche, la tige conductrice coudée étant maintenue par un isolant à l'intérieur d'un conduit interne en forme de L réalisé dans le corps, caractérisé par le fait que ledit isolant présente un rétrécissement de section définissant une couche d'air autour d'une partie au moins de la branche rectiligne de ladite tige.The present invention relates to a bent coaxial connector element of the type comprising a substantially parallelepipedic conductive body, at least one bent conductive rod, one end of which is connected to a pin projecting from one of the faces of said body and the other of which end is connected to the central conductor of a coaxial contact, projecting from another face of said body and perpendicular to the pin, the angled conductive rod being held by an insulator inside an internal L-shaped conduit produced in the body, characterized in that said insulator has a narrowing in section defining an air layer around at least part of the straight branch of said rod.

Ce rétrécissement de section permet de ménager un espace annulaire rempli d'air autour d'une partie au moins des branches rectilignes de l'isolant, ce qui permet d'ajuster convenablement l'impédance de la ligne électrique constituée par la tige conductrice coudée.This narrowing of the section makes it possible to provide an annular space filled with air around at least part of the rectilinear branches of the insulation, which makes it possible to suitably adjust the impedance of the electrical line formed by the bent conductive rod.

De préférence, l'isolant comporte, au voisinage de la partie coudée de la tige conductrice coudée, des surfaces en appui contre la paroi intérieure du conduit interne en forme de L.Preferably, the insulator comprises, in the vicinity of the bent part of the bent conductive rod, surfaces bearing against the inner wall of the L-shaped internal conduit.

Avantageusement, l'isolant comporte également, aux extrémités de la tige conductrice coudée, des surfaces en appui d'une part contre la paroi intérieure du conduit interne en forme de L, d'autre part contre la paroi intérieure du manchon externe du contact coaxial.Advantageously, the insulator also comprises, at the ends of the bent conductive rod, surfaces bearing on the one hand against the internal wall of the L-shaped internal conduit, on the other hand against the internal wall of the external sleeve of the coaxial contact .

Grâce à un tel isolant, on peut exercer une pression sur l'élément de connecteur sans le détériorer, la force résultant de cette pression s'exerçant, au travers de la paroi du corps de l'élément de connecteur, sur la tige conductrice coudée, laquelle transmet cet effort aux broches en saillie pénétrant dans les orifices prévus à cet effet sur la carte imprimée.Thanks to such an insulator, pressure can be exerted on the connector element without damaging it, the force resulting from this pressure being exerted, through the wall of the body of the connector element, on the bent conductive rod. , which transmits this force to the projecting pins penetrating into the orifices provided for this purpose on the circuit board.

Ainsi, on peut utiliser des contacts insérables à force comme broches permettant le raccordement de l'élément de connecteur coudé sur la carte imprimée.Thus, force-insertable contacts can be used as pins allowing the connection of the elbow connector element on the printed circuit board.

Dans un mode de réalisation préféré de l'invention, le corps de l'élément coudé de connecteur coaxial est réalisé en deux parties s'encastrant l'une dans l'autre, le plan principal de séparation de ces deux parties passant sensiblement par les axes des deux branches de la tige conductrice coudée.In a preferred embodiment of the invention, the body of the elbow element of the coaxial connector is produced in two parts which fit into one another, the main plane of separation of these two parts passing substantially through the axes of the two branches of the bent conductive rod.

Grâce à un tel agencement, la tige conductrice coudée dotée de son isolant peut être aisément insérée à l'intérieur du corps de l'élément de connecteur selon l'invention, avant assemblage des deux parties dont il est constitué.Thanks to such an arrangement, the angled conductive rod provided with its insulator can be easily inserted inside the body of the connector element according to the invention, before assembly of the two parts of which it is made.

Dans le but de mieux faire comprendre l'invention, on va en décrire maintenant un mode de réalisation donné à titre d'exemple sans aucun caractère limitatif, en référence au dessin annexé dans lequel :

  • la figure 1 est une vue en coupe partielle d'un connecteur coaxial comportant un élément coudé selon l'invention et un élément droit,
  • la figure 2 est une vue de dessous de la figure 1,
  • la figure 3 est une vue en coupe selon III-III de la figure 1,

  • la figure 6 est une vue en coupe partielle selon VI-VI de la figure 1, et
  • la figure 7 est une vue en coupe selon VII-VII de la figure 1.
In order to better understand the invention, we will now describe an embodiment given by way of example without any limiting character, with reference to the accompanying drawing in which:
  • FIG. 1 is a partial section view of a coaxial connector comprising an elbow element according to the invention and a straight element,
  • FIG. 2 is a bottom view of FIG. 1,
  • FIG. 3 is a sectional view along III-III of FIG. 1,
  • FIG. 4 is a sectional view along IV-IV of FIG. 1,
  • FIG. 5 is a sectional view along VV of FIG. 1,
  • FIG. 6 is a partial sectional view along VI-VI of FIG. 1, and
  • Figure 7 is a sectional view along VII-VII of Figure 1.

Sur le dessin, on a représenté un connecteur coaxial comportant un élément coudé, désigné globalement par 1, et un élément droit, désigné globalement par 2.In the drawing, a coaxial connector is shown comprising a bent element, generally designated by 1, and a straight element, generally designated by 2.

Dans le mode de réalisation représenté, l'élément coudé est monté sur une première carte imprimée 3, dite carte fille, tandis que l'élément droit 2 est monté sur une seconde carte imprimée 4, dite carte mère.In the embodiment shown, the bent element is mounted on a first printed card 3, called the daughter card, while the straight element 2 is mounted on a second printed card 4, called the mother card.

Par rapprochement axial des deux éléments de connecteur 1 et 2 dans leur position représentée sur la figure 1, on raccorde la carte fille 3 à la carte mère 4.By axial approximation of the two connector elements 1 and 2 in their position shown in FIG. 1, the daughter card 3 is connected to the mother board 4.

L'élément coudé 1 comporte un corps de forme sensiblement parallélépipèdique 5, réalisé de préférence en un matériau métallique tel qu'un alliage léger zinc-aluminium, par exemple l'alliage connu sous le nom de Zamak® qui est constitué de 96% de zinc et de 4% d'aluminium.The bent element 1 comprises a body of substantially parallelepiped shape 5, preferably made of a metallic material such as a light zinc-aluminum alloy, by example the alloy known as Zamak® which consists of 96% zinc and 4% aluminum.

Le corps parallélépipédique 5 comporte intérieurement deux conduits 6 et 7, en forme de L, qui débouchent sur deux faces orthogonales 5a et 5b du corps 5.The parallelepipedic body 5 has two L-shaped conduits 6 and 7 internally, which open onto two orthogonal faces 5 a and 5 b of the body 5.

Les axes des deux conduits 6 et 7 se situent dans un même plan qui est sensiblement un plan médian du corps 5.The axes of the two conduits 6 and 7 lie in the same plane which is substantially a median plane of the body 5.

On désigne par face inférieure la face 5a et par face frontale la face 5b.The bottom face 5 a and the front face 5 b are designated.

Deux tiges conductrices coudées 8 et 9 sont logées dans les conduits 6 et 7 en forme de L et relient des broches de contact 10, 11 en saillie de la face inférieure 5a à des conducteurs centraux 12, 13 de contacts coaxiaux 14, 15 en saillie de la face frontale 5b.Two angled conductive rods 8 and 9 are housed in the L-shaped conduits 6 and 7 and connect contact pins 10, 11 projecting from the underside 5 a to central conductors 12, 13 of coaxial contacts 14, 15 in projection of the front face 5 b .

Les axes des tiges conductrices coudées 8 et 9 se situent dans le plan médian contenant les axes des conduits 6 et 7.The axes of the angled conductive rods 8 and 9 are located in the median plane containing the axes of the conduits 6 and 7.

Dans le mode de réalisation représenté, les broches de contact 10 et 11 sont du type insérables à force, c'est-à-dire qu'elles sont élastiquement déformables radialement. Leur section présente des dimensions légèrement supérieures à celles d'orifices 16, 17, ménagés dans la carte imprimée 3, et dans lesquels lesdites broches de contact 10, 11 sont destinées à être introduites.In the embodiment shown, the contact pins 10 and 11 are of the force-insertable type, that is to say that they are elastically deformable radially. Their section has dimensions slightly greater than those of orifices 16, 17, formed in the printed card 3, and in which said contact pins 10, 11 are intended to be introduced.

Chaque orifice 16, 17 comporte une métallisation assurant le contact électrique entre des circuits imprimés de la carte 3 et les broches de contact 10, 11.Each orifice 16, 17 includes a metallization ensuring electrical contact between the printed circuits of the card 3 and the contact pins 10, 11.

Conformément à l'invention, chaque tige conductrice coudée 8, 9 est dotée d'un isolant 18, 19 qui comporte des surfaces 18a et 19a en appui contre la paroi intérieure du conduit correspondant 6, 7 en forme de L, notamment au voisinage de la partie coudée de ladite tige conductrice.According to the invention, each bent conductive rod 8, 9 is provided with an insulator 18, 19 which has surfaces 18 a and 19 a resting against the inner wall of the corresponding conduit 6, 7 in an L shape, in particular at near the bent part of said conductive rod.

Grâce à l'isolant 18, 19, on peut exercer une pression sur le corps 5 dans la direction indiquée par la flèche F, pour insérer à force les broches de contact 10, 11 dans les trous métallisés 16, 17.By means of the insulator 18, 19, pressure can be exerted on the body 5 in the direction indicated by the arrow F, in order to force the contact pins 10, 11 into the metallized holes 16, 17.

L'absence de jeu au voisinage des coudes des tiges conductrices coudées 8, 9 évite toute déformation des pièces composant l'élément de connecteur coudé 1, et par suite toute dégradation de celles-ci.The absence of play in the vicinity of the elbows of the bent conductive rods 8, 9 prevents any deformation of the parts component of the elbow connector element 1, and consequently any degradation thereof.

Selon l'invention, pour réaliser l'isolant 18, 19, on utilise des matériaux ayant de bonnes caractéristiques diélectriques aux hautes fréquences, par exemple un polyéthérimide tel que celui connu sous le nom de ULTEM, ou un copolymère d'éthylène et de monochlorotrifluoréthylène, tel que celui connu sous le nom de HALAR.According to the invention, to produce the insulator 18, 19, materials having good dielectric characteristics at high frequencies are used, for example a polyetherimide such as that known under the name of ULTEM, or a copolymer of ethylene and monochlorotrifluoroethylene , such as the one known as HALAR.

Pour ajuster convenablement, par exemple à 50 ohms, l'impédance de la ligne électrique constituée par chaque tige conductrice coudée 8, 9, il est avantageux de libérer un espace autour de l'isolant 18, 19 de manière à créer une couche annulaire d'air 18',19' autour d'une partie au moins des branches rectilignes de chaque tige.To suitably adjust, for example to 50 ohms, the impedance of the electric line formed by each bent conductive rod 8, 9, it is advantageous to free up a space around the insulation 18, 19 so as to create an annular layer d 'air 18', 19 'around at least part of the straight branches of each rod.

A cet effet, les isolants 18 et 19 comportent un rétrécissement de section dans leurs parties courantes.For this purpose, the insulators 18 and 19 include a narrowing of section in their current parts.

En revanche, aux extrémités des tiges conductrices coudées 8 et 9, l'isolant comporte des surfaces 18b,19b; 18c, 19c en appui, d'une part, contre le conduit 6,7 en forme de L du côté de la carte fille 3, et d'autre part, contre le manchon externe du contact coaxial 14, 15 du côté de la carte mère 4.On the other hand, at the ends of the angled conductive rods 8 and 9, the insulator has surfaces 18 b , 19 b ; 18 c , 19 c in abutment, on the one hand, against the L-shaped conduit 6,7 on the side of the daughter card 3, and on the other hand, against the external sleeve of the coaxial contact 14, 15 on the side of the motherboard 4.

L'élément coudé 1 comporte dans l'exemple illustré six broches de contact de masse 20 également insérées à force dans la carte imprimée 3.The bent element 1 comprises in the illustrated example six ground contact pins 20 also inserted by force into the circuit board 3.

Les broches de contact 20 présentent chacune une section en V, visible sur la vue de dessous de la figure 2. Chaque broche de contact de masse 20 est une partie découpée et recourbée d'une plaque de masse commune 21 dont la section en U est visible sur les figures 6 et 7.The contact pins 20 each have a V-shaped section, visible in the bottom view of FIG. 2. Each ground contact pin 20 is a cut and bent part of a common ground plate 21, the U-section of which is visible in Figures 6 and 7.

Sur la figure 6, l'isolant 18 est représenté plein.In Figure 6, the insulator 18 is shown full.

Dans le mode de réalisation représenté, le corps parallélépipédique 5 de l'élément coudé 1 est réalisé en deux parties 22 et 23 qui sont clairement visibles sur les vues en coupe des figures 3 à 7.In the embodiment shown, the parallelepiped body 5 of the bent element 1 is produced in two parts 22 and 23 which are clearly visible in the sectional views of FIGS. 3 to 7.

A l'état monté du corps 5, les parties 22 et 23 sont assemblées essentiellement au niveau du plan contenant les axes des deux conduits 6 et 7 en forme de L.In the assembled state of the body 5, the parts 22 and 23 are assembled essentially at the level of the plane containing the axes of the two conduits 6 and 7 in an L shape.

La partie 22 s'étend sur toute la longueur du corps parallélépipédique 5 et comporte, du côté de la face frontale 5b dudit corps, un retour 22a auquel sont assujettis les contacts coaxiaux 14 et 15.The part 22 extends over the entire length of the parallelepiped body 5 and comprises, on the side of the front face 5 b of said body, a return 22 a to which the coaxial contacts 14 and 15 are subjected.

Les parties 22, 23 comportent chacune deux gorges demi-cylindriques coudées sur leurs faces en regard, ces deux gorges constituent les conduits 6 et 7 en forme de L du corps parallélépipédique 5, lorsque les deux parties 22, 23 sont réunies.The parts 22, 23 each have two semi-cylindrical grooves bent on their opposite faces, these two grooves constitute the conduits 6 and 7 in the form of L of the parallelepiped body 5, when the two parts 22, 23 are joined.

On voit clairement, notamment sur les figures 5 et 6, que la section des isolants 18 et 19 coïncide avec celle des conduits 6 et 7 au niveau des parties coudées des tiges conductrices 8 et 9.It is clearly seen, in particular in FIGS. 5 and 6, that the section of the insulators 18 and 19 coincides with that of the conduits 6 and 7 at the bent parts of the conductive rods 8 and 9.

L'assemblage de l'élément coudé 1 s'effectue de la manière suivante.The assembly of the elbow element 1 is carried out as follows.

On place d'abord les tiges conductrices coudées 8 et 9 surmoulées de leurs isolants 18 et 19 dans les gorges correspondantes des parties 22 et 23.First place the angled conductive rods 8 and 9 overmolded with their insulators 18 and 19 in the corresponding grooves of the parts 22 and 23.

On assemble ensuite ces parties entre elles.These parts are then assembled together.

La partie 22 comporte à cet effet quatre orifices évasés vers l'extérieur 24 dans lesquels pénètrent des plots 25 solidaires de la partie 23.Part 22 therefore has four outwardly flared orifices 24 into which studs 25 integral with part 23 penetrate.

Après assemblage des deux parties 22 et 23, chaque plot 25 est riveté, son extrémité ainsi aplatie étant retenue dans l'embouchure évasée de l'orifice 24.After assembly of the two parts 22 and 23, each stud 25 is riveted, its end thus flattened being retained in the flared mouth of the orifice 24.

Les manchons externes des contacts coaxiaux 14 et 15 sont ensuite insérés en force dans les orifices 26 prévus à cet effet sur la face 5b de la partie 22.The external sleeves of the coaxial contacts 14 and 15 are then forcibly inserted into the orifices 26 provided for this purpose on the face 5b of the part 22.

Par sécurité, ces manchons sont maintenus en position par sertissage de la partie 22 autour d'une gorge 26a prévue sur chaque manchon, comme on le voit clairement sur la figure 4.For security, these sleeves are held in position by crimping the portion 22 around a groove 26 is provided on each sleeve, as seen clearly in Figure 4.

Enfin, la plaque de masse 21 est fixée par rivetage à la face inférieure 5a du corps 5, qui comporte des plots 27 pénétrant dans des orifices 28 de la plaque 21.Finally, the ground plate 21 is fixed by riveting to the lower face 5 a of the body 5, which has studs 27 penetrating into orifices 28 in the plate 21.

De cette manière, on réalise d'une façon particulièrement simple un élément coudé de connecteur coaxial qui est susceptible de comporter des contacts insérables à force en tant que broches de raccordement à une carte imprimée.In this way, an elbow element of coaxial connector is produced in a particularly simple manner which is capable of comprising contacts which can be inserted by force as pins for connection to a printed circuit board.

Il est bien entendu que le mode de réalisation qui vient d'être décrit ne présente aucun caractère limitatif.It is understood that the embodiment which has just been described has no limiting character.
