Description

L'invention concerne un connecteur du type à picots coudés, embrochables éventuellement à force ("press-fit") sur une carte de circuit imprimé.The invention relates to a connector of the bent pin type, possibly force-fit ("press-fit") on a printed circuit board.

Plus précisément, un tel connecteur comporte un corps isolant portant une série de picots coudés dont les branches proximales (par rapport à la carte) sont essentiellement perpendiculaires à la carte et peuvent présenter un profil permettant l'embrochage à force dans un trou métallisé du circuit imprimé, et dont les branches distales (par rapport à la carte) sont essentiellement parallèles à la carte et sont solidaires d'une partie active disposée dans le corps isolant et configurée en organe, mâle ou femelle, de connexion.More specifically, such a connector comprises an insulating body carrying a series of bent pins whose proximal branches (relative to the card) are essentially perpendicular to the card and can have a profile allowing the force fitting in a metallized hole of the circuit. printed, and whose distal branches (relative to the card) are essentially parallel to the card and are integral with an active part disposed in the insulating body and configured as a member, male or female, of connection.

L'embrochage à force des picots dans les trous métallisés de la carte est en principe effectué une fois pour toutes (sauf à permettre deux ou trois démontages du connecteur, par exemple pour des opérations de réparation). Les organes de connexion portés par les branches distales des picots sont destinés à réaliser des liaisons électriques essentiellement démontables, par exemple avec un connecteur du type rectangulaire.The force-fitting of the pins in the metallized holes of the card is in principle carried out once and for all (unless allowing two or three dismantling of the connector, for example for repair operations). The connection members carried by the distal branches of the pins are intended to produce essentially removable electrical connections, for example with a connector of the rectangular type.

Le montage sur la carte d'un connecteur embrochable à force est généralement réalisé par appui direct sur les picots dans leur région coudée, afin de provoquer l'enfoncement de ceux-ci dans les trous métallisés en vis-à-vis. La force nominale d'insertion est élevée, de l'ordre de 50 N par picot.The mounting on the card of a force-fit connector is generally carried out by direct pressing on the pins in their bent region, in order to cause the latter to sink into the metallized holes opposite. The nominal insertion force is high, of the order of 50 N per spike.

Cette opération a pour inconvénient de nécessiter un outillage spécifique pour chaque connecteur, afin de venir appuyer simultanément et de façon uniforme sur chacun des picots du connecteur.This operation has the disadvantage of requiring a specific tool for each connector, in order to press simultaneously and uniformly on each of the pins of the connector.

La demande de brevet européen EP-A-0 335 160 (HARTING ELEKTRONIK GmbH) concerne un connecteur comportant un corps isolant arrière muni de blocs d'appui. Ces blocs ne comportent aucune face de maintien des contacts suivant une direction horizontale. En outre, il est nécessaire d'ajouter un élément complémentaire sous la forme d'une poutre afin de maintenir les contacts suivant la direction horizontale. La solution proposée ne permet pas le maintien de toutes les rangées. La poussée doit s'effectuer exactement sur le dessus de la rangée des pattes : un outil spécifique est d'ailleurs prévu à cet effet .European patent application EP-A-0 335 160 (HARTING ELEKTRONIK GmbH) relates to a connector comprising a rear insulating body provided with support blocks. These blocks have no contact holding face in a horizontal direction. In addition, it is necessary to add a complementary element in the form of a beam in order to maintain the contacts in the horizontal direction. The proposed solution does not allow the maintenance of all rows. The push must be carried out exactly on the top of the row of legs: a specific tool is also provided for this purpose.

Il est par ailleurs souhaitable, notamment dans le cas de picots coudés destinés à être soudés sur un circuit imprimé, que ceux-ci soient maintenus en place de manière précise de telle sorte que les picots soient réalignés avec les trous.It is moreover desirable, in particular in the case of bent pins intended to be soldered on a printed circuit, that these are held in place in a precise manner so that the pins are realigned with the holes.

L'invention se propose de remédier à cet inconvénient, grâce à un connecteur dont le corps isolant présente une géométrie spécifique qui permet l'appui simultané sur tous les contacts lors de l'embrochage du connecteur sur la carte de circuit imprimé.The invention proposes to remedy this drawback, thanks to a connector whose insulating body has a specific geometry which allows simultaneous pressing on all the contacts when the connector is plugged into the printed circuit board.

Le connecteur embrochable sur une carte de circuit imprimé comportant des trous metallisés, présente une partie avant comportant un premier corps isolant dans lequel sont disposés des éléments de connexion dits picots coudés comportant une extrémité distale configurée en contact mâle ou femelle de connexion, une branche distale destinée à être disposée sensiblement parallèle à une telle carte, un coude reliant la branche distale à la branche proximale du picot, essentiellement perpendiculaire à la branche distale, une extrémité proximale présentant un profil permettant l'embrochage dans un desdits trous métallisés, caractérisé en ce qu'il comporte un deuxième corps isolant présentant des fentes superposées deux à deux destinées à recevoir des picots coudés situés deux à deux dans un même plan perpendiculaire à une telle carte, chaque fente présentant une première face essentiellement parallèle à la branche distale et destinée à permettre une poussée sur les branches distales pendant l'embrochage desdites extrémités proximales dans la carte et lesdites fentes présentent une deuxième face essentiellement perpendiculaire à la première face pour maintenir en position les branches proximales dans la direction d'insertion des organes de connexion.The plug-in connector on a printed circuit board comprising metallized holes has a front part comprising a first insulating body in which are arranged connection elements called bent pins having a distal end configured in male or female connection contact, a distal branch intended to be disposed substantially parallel to such a card, an elbow connecting the distal branch to the proximal branch of the pin, essentially perpendicular to the distal branch, a proximal end having a profile allowing racking in one of said metallized holes, characterized in that that it comprises a second insulating body having slots superposed two by two intended to receive bent pins located two by two in the same plane perpendicular to such a card, each slot having a first face essentially parallel to the distal branch and intended to allow a p pushed on the distal branches during the racking of said proximal ends in the card and said slots have a second face substantially perpendicular to the first face to maintain in position the proximal branches in the direction of insertion of the connection members.

Lesdites fentes peuvent présenter une troisième et une quatrième faces d'appui pour positionner les branches proximales dans la direction d'insertion des organes de connexion.Said slots can have a third and a fourth bearing faces for position the proximal branches in the direction of insertion of the connecting members.

Selon un mode de réalisation avantageuse, les fentes appartenant à des rangées différentes de contacts ont des longueurs différentes parallèlement et perpendiculairement à la carte.According to an advantageous embodiment, the slots belonging to different rows of contacts have different lengths parallel and perpendicular to the card.

Selon un mode de réalisation préféré, un connecteur selon l'invention est caractérisé en ce que chaque fente présente deux parties, à savoir d'une part une première partie formant une fente d'introduction débouchant sur une face supérieure du deuxième corps isolant et présentant une cinquième face essentiellement perpendiculaire à la carte pour recevoir une branche proximale d'un dit picot coudé introduit verticalement par ladite face supérieure par sa dite extrémité proximale ainsi qu'une sixième face essentiellement parallèle à la carte pour former une butée pour la branche distale dudit picot et d'autre part une deuxième partie formant une fente de maintien et présentant au moins ladite première face, de telle sorte que la première face coopère avec la branche distale par introduction horizontale.According to a preferred embodiment, a connector according to the invention is characterized in that each slot has two parts, namely on the one hand a first part forming an insertion slot opening onto an upper face of the second insulating body and having a fifth face essentially perpendicular to the card to receive a proximal branch of a said bent pin introduced vertically by said upper face by its said proximal end as well as a sixth face essentially parallel to the card to form a stop for the distal branch of said pin and on the other hand a second part forming a holding slot and having at least said first face, so that the first face cooperates with the distal branch by horizontal introduction.

La distance séparant verticalement la première face et la sixième face est avantageusement sensiblement supérieure à la hauteur h d'une branche distale d'un picot coudé.The distance vertically separating the first face and the sixth face is advantageously substantially greater than the height h of a distal branch of a bent pin.

Le corps isolant peut présenter des plots de hauteur calibrée au voisinage desdits profils. Ceci permet d'assurer un calibrage de la profondeur d'emmanchement dans le cas d'une insertion à force ("press-fit") et le rattrapage des tolérances de fabrication et du tassement (recul élastique) de l'isolant arrière lors de l'insertion de façon à obtenir une insertion complète des picots.The insulating body may have studs of calibrated height in the vicinity of said profiles. This ensures a calibration of the fitting depth in the case of a force fit ("press-fit") and the catching up of manufacturing tolerances and compaction (elastic recoil) of the rear insulation during insertion so as to obtain a complete insertion of the pins.

Des bras de verrouillage peuvent être disposés à deux extrémités longitudinales opposées du deuxième corps isolant. Le premier corps isolant peut être fixé dans un boîtier, le deuxième corps isolant étant monté sur le boîtier par coopération entre les bras de verrouillage et des encoches disposées à deux extrémités longitudinales opposées dudit boîtier.Locking arms can be arranged at two opposite longitudinal ends of the second insulating body. The first insulating body can be fixed in a housing, the second insulating body being mounted on the housing by cooperation between the locking arms and notches arranged at two opposite longitudinal ends of said housing.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description qui va suivre, en liaison avec les dessins qui représentent :

  • les figures 1a à 1c, en coupe verticale B-B, les étapes d'assemblage d'un connecteur selon l'invention ;
  • les figures 2a et 2b, des vues en perspective d'un connecteur de type rectangulaire, la figure 2b représentant un connecteur assemblé selon l'invention ; et
  • la figure 3, une vue de dessus avec coupe partielle d'un connecteur assemblé selon l'invention.
Other characteristics and advantages of the invention will appear on reading the description which follows, in conjunction with the drawings which represent:
  • Figures 1a to 1c, in vertical section BB, the steps of assembling a connector according to the invention;
  • Figures 2a and 2b, perspective views of a rectangular type connector, Figure 2b showing an assembled connector according to the invention; and
  • Figure 3, a top view with partial section of an assembled connector according to the invention.

Sur les figures, un connecteur de type rectangulaire 5 présente un bloc central isolant 10 présentant une partie arrière 11 et une partie avant 32 dont le contour s'inscrit à l'intérieur de celui de la partie arrière 11. Des contacts mâles ou femelles de connexion 70 faisant partie de picots coudés 61 sont disposés dans le bloc 10. Les extrémités longitudinales 17 du bloc central isolant 10 présentent un élément de poutre 41 se prolongeant par deux bras élastiques 42 et 43 qui lui sont perpendiculaires. L'élément de poutre 41 est verrouillé par un ergot 50 présentant un profil incliné 51 et une région 53 formant butée. Un capot de blindage 3 entoure, en 34, la partie avant 32 du bloc isolant 10 et encadre, en 38, les portions supérieure et inférieure de la partie arrière 11. Il est en butée en 35 entre celui-ci et un cadre (28-25) d'un boîtier 1, par exemple en matériau conducteur. Le corps métallique formant boîtier 1 présente une face arrière portant deux bords longitudinaux supérieur et inférieur respectivement 28 et 29 et deux trièdes composés d'éléments orthogonaux référencés 22, 24 et 25 permettant, notamment grâce à des ouvertures 24', la fixation du boîtier 2 sur un support tel qu'un châssis ou bien un circuit imprimé.In the figures, a rectangular type connector 5 has an insulating central block 10 having a rear part 11 and a front part 32 whose outline is inscribed inside that of the rear part 11. Male or female contacts of connection 70 forming part of bent pins 61 are arranged in the block 10. The longitudinal ends 17 of the insulating central block 10 have a beam element 41 extended by two elastic arms 42 and 43 which are perpendicular thereto. The beam element 41 is locked by a lug 50 having an inclined profile 51 and a region 53 forming a stop. A shielding cover 3 surrounds, at 34, the front part 32 of the insulating block 10 and frames, at 38, the upper and lower portions of the rear part 11. It abuts at 35 between the latter and a frame (28 -25) of a housing 1, for example of conductive material. The metal body forming a casing 1 has a rear face carrying two upper and lower longitudinal edges 28 and 29 respectively and two compound triedes orthogonal elements referenced 22, 24 and 25 allowing, in particular through openings 24 ', the fixing of the housing 2 on a support such as a chassis or a printed circuit.

Chaque triède comporte d'une part un élément vertical 25 venant prolonger le bord supérieur 28 en direction du bord inférieur 29, et d'autre part, un élément 22 également vertical mais perpendiculaire au bord supérieur 28 et se raccordant à l'élément 25. Le bord inférieur 29 s'étend entre les deux éléments 22. Enfin, le triède est complété par un élément horizontal 24. Les éléments 22 présentent des encoches 23 destinées à coopérer avec les extrémités 67 des bras élastiques 66 d'un corps isolant 60 et qui sont disposés aux extrémités longitudinales du corps isolant 60.Each tried comprises on the one hand a vertical element 25 extending from the upper edge 28 towards the lower edge 29, and on the other hand, an element 22 also vertical but perpendicular to the upper edge 28 and connecting to the element 25. The lower edge 29 extends between the two elements 22. Finally, the triede is completed by a horizontal element 24. The elements 22 have notches 23 intended to cooperate with the ends 67 of the elastic arms 66 of an insulating body 60 and which are arranged at the longitudinal ends of the insulating body 60.

La partie avant 32 présente des ouvertures débouchantes 16 dans lesquelles sont logés les contacts 70 qui se prolongent vers l'arrière par des picots coudés 61.The front part 32 has through openings 16 in which the contacts 70 are housed, which are extended towards the rear by bent pins 61.

La partie arrière du connecteur embrochable à force 4 présente un corps central isolant 60 dans lequel sont logés les picots 61 coudés à 90° en 62 et comportant une branche proximale 65 (par rapport à la carte) se prolongeant par des profils 63 qui peuvent être du type permettant l'embrochage à force ("press-fit") dans un trou métallisé d'un circuit imprimé 80.The rear part of the force-fit plug-in connector 4 has an insulating central body 60 in which are housed the pins 61 bent at 90 ° at 62 and comprising a proximal branch 65 (relative to the card) extended by profiles 63 which can be of the type allowing press-fit into a metallized hole in a printed circuit 80.

La branche distale 64 (par rapport à la carte 80) jouxte une surface d'appui 71 d'une rainure 90. Cette surface d'appui 71 est essentiellement parallèle à la carte 80 et constitue ainsi une surface d'appui permettant l'insertion des profils 63, en particulier une insertion à force. Les branches proximales 65 (par rapport à la carte 80) sont quant à elles entourées de trois surfaces d'appui 72, 73, 74 de la fente. Ces surfaces 72, 73, 74 ont une section en forme de U et encadrent les branches proximales 65 dans la direction d'insertion des profils 63 et perpendiculairement de part et d'autre de la direction d'insertion (voir encadré de la figure 3).The distal branch 64 (relative to the card 80) adjoins a bearing surface 71 of a groove 90. This bearing surface 71 is essentially parallel to the card 80 and thus constitutes a bearing surface allowing insertion profiles 63, in particular a forced insertion. The proximal branches 65 (relative to the card 80) are in turn surrounded by three bearing surfaces 72, 73, 74 of the slot. These surfaces 72, 73, 74 have a U-shaped section and surround the proximal branches 65 in the direction profiles 63 and perpendicularly on either side of the insertion direction (see box in Figure 3).

On remarquera également sur les dessins que les fentes 90 ont des longueurs inégales aussi bien perpendiculairement à la carte que parallèlement à celle-ci, et que deux picots de longueurs différentes sont situés dans le même plan vertical (plan de coupe B-B). L'assemblage d'un connecteur s'effectue à partir d'un corps isolant 10 monté dans un boîtier 1 essentiellement conducteur.It will also be noted in the drawings that the slots 90 have unequal lengths both perpendicularly to the card and parallel to it, and that two pins of different lengths are located in the same vertical plane (cutting plane B-B). The assembly of a connector is carried out from an insulating body 10 mounted in a case 1 which is essentially conductive.

La géométrie du corps central 60 présentant les fentes 90 permet tout d'abord par un mouvement vertical (figure 1A) de présenter l'extrémité distale des picots coudés 61 par la face supérieure 81 du corps isolant 60 (insertion par déplacement du corps isolant 60 suivant la flèche F1). Lors de cette première étape, les branches proximales 65 coulissent le long des faces verticales 76 faisant partie de fentes d'introduction 91, sauf pour la rangée de picots située à proximité immédiate de la partie avant 11 et qui jouxtent la face avant 79 du corps isolant 60. Les faces verticales 76 sont légèrement inclinées pour guider les profils 63. Des faces verticales 78 situées à l'opposé des faces 76, mais à une partie inférieure du corps isolant 60, coopèrent avec les fentes 76 pour guider les profils 63 et les branches proximales 65 sur une partie substantielle de la course verticale du corps isolant 60.The geometry of the central body 60 having the slots 90 allows first of all by a vertical movement (FIG. 1A) to present the distal end of the bent spikes 61 by the upper face 81 of the insulating body 60 (insertion by displacement of the insulating body 60 according to arrow F 1 ). During this first step, the proximal branches 65 slide along the vertical faces 76 forming part of insertion slots 91, except for the row of pins located in the immediate vicinity of the front part 11 and which adjoin the front face 79 of the body insulator 60. The vertical faces 76 are slightly inclined to guide the profiles 63. Vertical faces 78 situated opposite the faces 76, but at a lower part of the insulating body 60, cooperate with the slots 76 to guide the profiles 63 and the proximal branches 65 over a substantial part of the vertical stroke of the insulating body 60.

En fin de cette première étape (position représentée à la figure 1B), les branches distales 64 viennent pratiquement en butée sur des faces horizontales 77 (sauf pour la rangée de picots 61 la plus proche de la partie avant 11), et leur débattement latéral est limité par les bords verticaux 82 encadrant les faces horizontales 77. Les faces horizontales 77, les bords verticaux 82 et les faces verticales 76 définissent ainsi des fentes d'introduction 91 des picots coudés 61.At the end of this first step (position shown in FIG. 1B), the distal branches 64 come into practically abutment on horizontal faces 77 (except for the row of pins 61 closest to the front part 11), and their lateral movement is limited by the vertical edges 82 framing the horizontal faces 77. The horizontal faces 77, the vertical edges 82 and the vertical faces 76 thus define insertion slots 91 of bent pins 61.

La deuxième étape met en oeuvre un déplacement relatif horizontal (déplacement suivant la flèche F2 de la figure 1B) jusqu'à encliquetage des extrémités 67 des bras élastiques 66 dans les encoches 23 pour disposer les picots coudés 61 dans des fentes de positionnement 90 (position représentée à la figure 1C). Les branches proximales 65 se trouvent à proximité immédiate des bords verticaux 72, et les branches proximales sont en butée contre des bords horizontaux 71, et leur débattement latéral est limité par les bords verticaux 73 et 74 encadrant les faces 71 et 72 (voir encadré de la figure 3). Les coudes 62 sont situés en vis-à-vis de pans coupés 75 reliant les faces 71 et 72. Les faces horizontales 71, les faces verticales 72 et les bords verticaux 73 et 74 définissent ainsi des fentes de positionnement 90 des picots coudés 61, qui communiquent avec les fentes d'introduction 91 précitées. En particulier, la distance qui sépare verticalement les faces horizontales 71 et 77 correspondant aux picots coudés 61 situés dans un même plan est sensiblement supérieure à la hauteur h des branches proximales 64.The second step implements a horizontal relative displacement (displacement along arrow F 2 of FIG. 1B) until the ends 67 of the elastic arms 66 snap into place in the notches 23 to arrange the bent pins 61 in positioning slots 90 ( position shown in Figure 1C). The proximal branches 65 are in the immediate vicinity of the vertical edges 72, and the proximal branches are in abutment against horizontal edges 71, and their lateral movement is limited by the vertical edges 73 and 74 framing the faces 71 and 72 (see box of Figure 3). The elbows 62 are located opposite cut sides 75 connecting the faces 71 and 72. The horizontal faces 71, the vertical faces 72 and the vertical edges 73 and 74 thus define positioning slots 90 of the bent pins 61, which communicate with the aforementioned introduction slots 91. In particular, the distance which vertically separates the horizontal faces 71 and 77 corresponding to the bent spikes 61 situated in the same plane is substantially greater than the height h of the proximal branches 64.

Lors de l'insertion des profils 63 dans une carte de circuit imprimé 80 en particulier selon la technique d'insertion à force, les faces horizontales 71 servent de face d'appui et le corps central isolant 60 sert de pièce d'insertion, la presse d'insertion venant s'appuyer sur la face supérieure 81 du corps 60. Il n'est donc besoin de prévoir ni outillage ni pièce supplémentaire.During the insertion of the profiles 63 into a printed circuit board 80 in particular according to the force insertion technique, the horizontal faces 71 serve as a bearing face and the insulating central body 60 serves as an insertion piece, the insertion press coming to bear on the upper face 81 of the body 60. There is therefore no need to provide any tools or additional part.

On notera la manière dont est réalisée la fixation du connecteur 4 dans le connecteur rectangulaire 11, à savoir par coopération entre d'une part, des pattes élastiques 66 disposées aux extrémités longitudinales du corps 60, et d'autre part, des fentes 23 disposées sur les éléments 22 du trièdre. Sur les figures il y a ainsi quatre pattes 66 et quatre encoches 23. On notera que les encoches sont disposées d'une manière telle qu'elles permettent un certain jeu relatif entre les corps isolants 60 et 10.Note the manner in which the connector 4 is fixed in the rectangular connector 11, namely by cooperation between on the one hand, elastic tabs 66 disposed at the longitudinal ends of the body 60, and on the other hand, slots 23 arranged on the elements 22 of the trihedron. In the figures there are thus four tabs 66 and four notches 23. It will be noted that the notches are arranged in such a way that they allow a certain relative clearance between the insulating bodies 60 and 10.

Le corps isolant 60 assure un positionnement relatif précis entre les extrémités 63 lors de leur insertion.The insulating body 60 ensures precise relative positioning between the ends 63 during their insertion.

Des plots de hauteur calibrée 81, (ou pieds de lavage) disposés à la partie inférieure du bloc isolant 80 assurent un calibrage de la profondeur d'emmanchement du profil embrochable à force 63 et le rattrapage des tolérances de fabrication.Studs of calibrated height 81, (or washing feet) arranged at the lower part of the insulating block 80 ensure a calibration of the fitting depth of the plug-in profile with force 63 and the catching up of manufacturing tolerances.

Le dispositif décrit ci-dessus est plus particulièrement utilisable dans un connecteur tel que décrit dans la demande FR 91-15295 déposée le 10 décembre 1991 par la Demanderesse (FR-A-2 684 810, publié le 11 juin 1993), à savoir un connecteur embrochable à force comportant un corps isolant présentant une pièce en forme générale d'équerre présentant une aile de montage et une aile de liaison, et une pièce formant bloc de pression comportant des surfaces d'appui portant contre les branches distales des picots.The device described above is more particularly usable in a connector as described in application FR 91-15295 filed on December 10, 1991 by the Applicant (FR-A-2 684 810, published on June 11, 1993), namely a force-fit connector comprising an insulating body having a generally square-shaped part having a mounting wing and a connecting wing, and a pressure block part comprising bearing surfaces bearing against the distal branches of the pins.
