Description

L'invention concerne un connecteur pour carte de circuit imprimé, notamment pour une carte comportant un grand nombre de contacts.The invention relates to a connector for a printed circuit board, in particular for a card comprising a large number of contacts.

La présence d'un grand nombre de contacts sur une carte nécessite une certaine force à l'insertion et à l'extraction, et on a déjà cherché à réduire, ou même à supprimer cette force.The presence of a large number of contacts on a card requires a certain force for insertion and extraction, and attempts have already been made to reduce, or even eliminate this force.

On connaît déjà des connecteurs dans lesquels cette force d'insertion, ou d'extraction est supprimée. Un type de connecteur connu comporte deux branches articulées à une de leurs extrémités, l'une des branches au moins étant munie de contacts ; un support de contacts tel que par exemple un connecteur mâle ou une carte de circuit imprimé est introduit entre les deux branches que l'on rapproche ensuite. Dans un tel connecteur, il n'y a pas de guidage pour l'insertion ou l'extraction du support de contacts, et surtout il est difficile d'obtenir une pression identique sur tous les contacts qui s'échelonnent le long d'une branche.Connectors are already known in which this insertion or extraction force is eliminated. A known type of connector comprises two branches articulated at one of their ends, at least one of the branches being provided with contacts; a contact support such as for example a male connector or a printed circuit board is introduced between the two branches which are then brought together. In such a connector, there is no guide for inserting or extracting the contact support, and above all it is difficult to obtain identical pressure on all the contacts which extend along a plugged.

On connaît également un connecteur en forme de U avec des contacts à l'intérieur du U, sur chacune des branches, ledit connecteur comportant des moyens pour déplacer les contacts jusqu'à ce qu'ils viennent contre le support de contacts introduit entre les branches du U par l'extrémité ouverte dudit U. Un connecteur de ce type ne permet pas l'insertion d'un support de contacts par une de ses extrémités, ledit support de contacts glissant entre les branches.There is also known a U-shaped connector with contacts inside the U, on each of the branches, said connector comprising means for moving the contacts until they come against the contact support introduced between the branches U by the open end of said U. A connector of this type does not allow the insertion of a contact support by one of its ends, said contact support sliding between the branches.

Le connecteur à deux branches articulées permet une introduction par l'extrémité ouverte, mais l'ouverture des branches articulées, nécessaire pour l'insertion, rend ce type de connecteur encombrant et inutilisable dans un bâti comportant un grand nombre de connecteurs.The connector with two articulated branches allows insertion through the open end, but the opening of the articulated branches, necessary for insertion, makes this type of connector bulky and unusable in a frame comprising a large number of connectors.

On connaît par le document DE-A-2 110 947 un connecteur comportant des contacts se déplaçant dans un socle sous l'action d'un bloc mobile agissant sur l'extrémité des contacts. Une carte de circuit imprimé est introduite dans une rainure du socle et les contacts viennent, par déplacement du bloc mobile, presser sur la carte de circuit imprimé.Document DE-A-2 110 947 discloses a connector comprising contacts moving in a base under the action of a movable block acting on the end of the contacts. A printed circuit board is inserted into a groove in the base and the contacts come, by displacement of the movable block, to press on the printed circuit board.

Selon ce document il est nécessaire d'agir sur les contacts avant introduction de la carte, et de plus il n'est pas prévu d'utiliser une carte de circuit imprimé ayant des contacts sur deux faces ; pour cela il faudrait pratiquement doubler l'encombrement du connecteur de manière à prévoir un bloc mobile de chaque côté de la carte.According to this document, it is necessary to act on the contacts before introduction of the card, and moreover it is not intended to use a printed circuit card having contacts on two faces; for this it would practically double the size of the connector so as to provide a movable block on each side of the card.

On connaît également par le document GB-A-1 480 183 un connecteur pour carte de circuit imprimé, constitué par un socle comprenant une embase munie de contacts et un bloc mobile pour presser la carte contre lesdits contacts. Selon ce document la carte est introduite au-dessus des contacts, et pressée par le bloc mobile contre les contacts. Dans ce document la carte n'est pas solidaire du bloc mobile, et n'est donc pas vraiment entraînée par lui lors de son déplacement.Document GB-A-1 480 183 also discloses a connector for a printed circuit board, consisting of a base comprising a base provided with contacts and a movable block for pressing the card against said contacts. According to this document, the card is inserted above the contacts, and pressed by the movable block against the contacts. In this document, the card is not integral with the mobile unit, and is therefore not really driven by it during its movement.

Dans ce document la carte est introduite sans guide au-dessus de l'embase, de sorte qu'il peut y avoir frottement entre les contacts et la face de la carte en regard.In this document, the card is inserted without guide above the base, so that there may be friction between the contacts and the face of the card facing it.

La présente invention se propose de remédier aux inconvénients cités des connecteurs connus et a pour but un encombrement réduit permettant une insertion, et une extraction, longitudinale ou transversale, d'un support de contacts.The present invention proposes to remedy the aforementioned drawbacks of known connectors and aims to reduce the overall dimensions allowing insertion, and extraction, longitudinal or transverse, of a contact support.

La présente invention a également pour but un connecteur dans lequel l'insertion et l'extraction d'un support de contacts s'effectue sans frottement des contacts entre eux.The present invention also aims at a connector in which the insertion and the extraction of a contact support takes place without friction of the contacts between them.

L'invention a aussi pour but un connecteur utilisable aux extrémités opposées d'un support de contacts inséré longitudinalement entre les connecteurs.Another object of the invention is to provide a connector which can be used at the opposite ends of a contact support inserted longitudinally between the connectors.

L'invention a également pour but un connecteur permettant d'effectuer des connexions sur trois côtés d'un support de contacts.Another object of the invention is to provide a connector allowing connections to be made on three sides of a contact support.

Un autre but de l'invention est d'obtenir un connecteur assurant un verrouillage du support de contacts afin d'en empêcher son extraction lorsque les contacts électriques sont établis.Another object of the invention is to obtain a connector ensuring a locking of the contact support in order to prevent its extraction when the electrical contacts are established.

Selon l'invention, le connecteur pour carte de circuit imprimé, comprenant un socle comportant des contacts, un bloc mobile, et un dispositif de déplacement rotatif à came du bloc mobile traversant longitudinalement ledit bloc mobile qui prend, sous l'action du dispositif de déplacement, une position haute ou basse, est caractérisé par le fait que le socle comporte une embase munie desdits contacts, que le bloc mobile est parallèle à l'embase, que la carte de circuit imprimé est montée par une extrémité sur le bloc mobile parallèlement à l'embase, et que le bloc mobile se déplace perpendiculairement à l'embase pour permettre, en position haute, l'insertion au-dessus de l'embase de la carte de circuit imprimé qui comporte des contacts sur une face en regard de l'embase, et pour presser, en position basse, la carte de circuit imprimé contre lesdits contacts de l'embase, le bloc mobile entraînant la carte de circuit imprimé dans son déplacement.According to the invention, the connector for a printed circuit board, comprising a base comprising contacts, a movable block, and a rotary cam displacement device for the movable block passing longitudinally through said movable block which, under the action of the device, takes displacement, a high or low position, is characterized by the fact that the base comprises a base provided with said contacts, that the movable block is parallel to the base, that the printed circuit board is mounted by one end on the movable block in parallel to the base, and that the movable block moves perpendicular to the base to allow, in the high position, the insertion above the base of the printed circuit board which has contacts on a face opposite the base, and to press, in the low position, the printed circuit board against said contacts of the base, the movable block driving the printed circuit board in its movement.

Le bloc mobile 2, qui vient se loger entre les deux montants 6 et 7, a une forme générale de U avec une base 16, une première branche 17, et une deuxième branche 18 comportant une rainure longitudinale 19 ; les branches 17 et 18 sont plus courtes que la base 16 qui présente ainsi un talon 20 à chaque extrémité, la première branche ayant un talon 21 à chaque extrémité et la deuxième branche ayant un talon 22 à chaque extrémité, le talon 20 s'engageant dans les rainures d'angle 10 et 12, les talons 21 et 22 s'engageant dans les rainures d'angle 11 et 13. L'axe de commande 3 qui vient se loger entre les branches 17 et 18 du bloc mobile 2, comporte des cames 23, près de chaque extrémité et sur sa longueur ; lorsque l'axe de commande est en place, ses extrémités sont engagées dans les trous 8 et 9 des montants 6 et 7, et les cames près des extrémités dudit axe de commande viennent également s'engager partiellement chacune dans un logement 25 ménagé dans lesdits montants 6 et 7, logement qui limite la rotation de l'axe de commande et qui est mieux visible sur les figures 2 et 3 ; l'axe de commande comporte en bout, à l'une de ses extrémités, une fente 24 qui permet de le faire tourner.The movable block 2, which is housed between the two uprights 6 and 7, has a general shape of U with a base 16, a first branch 17, and a second branch 18 having a longitudinal groove 19; the branches 17 and 18 are shorter than the base 16 which thus has a heel 20 at each end, the first branch having a heel 21 at each end and the second branch having a heel 22 at each end, the heel 20 engaging in the corner grooves 10 and 12, the heels 21 and 22 engaging in the corner grooves 11 and 13. The control pin 3 which is received between the branches 17 and 18 of the movable block 2, comprises cams 23, near each end and along its length; when the control shaft is in place, its ends are engaged in the holes 8 and 9 of the uprights 6 and 7, and the cams near the ends of said control shaft also partially engage each in a housing 25 formed in said uprights 6 and 7, housing which limits the rotation of the control axis and which is better visible in Figures 2 and 3; the control shaft has at the end, at one of its ends, a slot 24 which allows it to rotate.

La figure 2 représente une coupe transversale du connecteur de la figure 1 ; le bloc mobile 2 est en position haute, la came 23 étant au contact de la première branche 17 du bloc mobile ; dans cette figure, on voit que la came 23 à l'extrémité de l'axe de commande 3 est engagée dans le logement 25 pratiqué dans le montant 7 du socle, ledit logement ayant la forme d'un secteur circulaire ; en position haute du bloc mobile, la came vient buter sur une extrémité dudit logement. Le socle est fixé sur un support 26, les contacts ayant leur extrémité 27 qui traverse ledit support aux fins de raccordement, ladite extrémité comportant un harpon 31 grâce auquel le contact est fixé de manière amovible dans le socle ; ces extrémités 27, ou queues, des contacts sont de forme quelconque afin de permettre le raccordement par soudure, par connexion enroulée, ou par connecteur pour câble en nappe s'enfichant sur lesdites queues : les contacts étant amovibles, il est donc possible d'équiper un socle d'un type donné de contacts, ou même de remplacer un contact. En position haute du bloc mobile, la rainure longitudinale 19 de celui-ci est alignée avec la rainure 14, figure 1, du montant 6, ce qui permet l'insertion d'un support de contacts 28, dont une extrémité glisse d'abord dans la rainure 14 puis dans la rainure 19 ; le support de contacts qui est par exemple une carte de circuit imprimé, comporte des contacts 29 qui sont des métallisations. Lorsque le support de contacts 28 est inséré dans le connecteur, il vient buter contre le montant 7 du socle, et n'est plus alors engagé dans la rainure 14 du montant 6 ; il est alors possible de faire tourner l'axe de commande 3, les cames 23 de celui-ci venant presser sur la deuxième branche 18 du bloc mobile 2 qui se déplace perpendiculairement à l'embase et prend la position basse représentée figure 3.Figure 2 shows a cross section of the connector of Figure 1; the movable block 2 is in the high position, the cam 23 being in contact with the first branch 17 of the movable block; in this figure, we see that the cam 23 at the end of the control shaft 3 is engaged in the housing 25 formed in the upright 7 of the base, said housing having the shape of a circular sector; in the high position of the movable block, the cam abuts on one end of said housing. The base is fixed on a support 26, the contacts having their end 27 which passes through said support for connection purposes, said end comprising a harpoon 31 by means of which the contact is removably fixed in the base; these ends 27, or tails, of the contacts are of any shape in order to allow connection by soldering, by wound connection, or by connector for ribbon cable plugging into said tails: the contacts being removable, it is therefore possible to equip a base with a given type of contact, or even replace a contact. In the high position of the movable block, the longitudinal groove 19 thereof is aligned with the groove 14, Figure 1, of the upright 6, which allows the insertion of a contact support 28, one end of which slides first in the groove 14 then in the groove 19; the contact support which is for example a printed circuit board, includes contacts 29 which are metallizations. When the contact support 28 is inserted in the connector, it abuts against the upright 7 of the base, and is no longer then engaged in the groove 14 of the upright 6; it is then possible to rotate the control axis 3, the cams 23 thereof pressing on the second branch 18 of the movable block 2 which moves perpendicular to the base and takes the low position shown in FIG. 3.

La figure 3 représente le connecteur de la figure 1 vu par son extrémité de gauche, et fixé sur le support 26 par un boulon 30, dans chacun des montants ; le bloc mobile 2 est en position basse, les cames 23 de l'axe de commande 3 venant presser sur la deuxième branche 18 du bloc mobile et buter contre une extrémité du logement 25. Le logement 25 en forme de secteur permet donc d'une part de limiter la rotation de l'axe de commande et d'autre part de définir les positions haute et basse du bloc mobile lorsque les cames 23 viennent buter sur l'une ou l'autre des extrémités dudit logement. Le bloc mobile 2, lorsqu'il passe de la position haute à la position basse, entraîne dans son déplacement le support de contacts 28 dont les contacts 29 viennent presser les contacts 5 de l'embase 4, ce qui établit un contact électrique entre chaque contact 5 et les contacts 29 correspondants.Figure 3 shows the connector of Figure 1 seen from its left end, and fixed to the support 26 by a bolt 30, in each of the uprights; the movable block 2 is in the low position, the cams 23 of the control shaft 3 coming to press on the second branch 18 of the movable block and abutting against one end of the housing 25. The housing 25 in the form of a sector therefore allows a firstly to limit the rotation of the control axis and secondly to define the high and low positions of the movable block when the cams 23 abut on one or the other of the ends of said housing. The movable block 2, when it goes from the high position to the low position, drives in its movement the contact support 28, the contacts 29 of which press the contacts 5 of the base 4, which establishes an electrical contact between each contact 5 and the corresponding contacts 29.

En position basse, la rainure 19 du bloc mobile est plus basse que la rainure 14 du montant 6, de sorte que le support de contacts 28 ne peut plus être extrait du connecteur, cette disposition des rainures 14 et 19 assure un verrouillage mécanique ; pour extraire le support de contacts 28, il est nécessaire de ramener le bloc mobile en position haute, ce qui supprime les contacts électriques entre les contacts du support de contacts et les contacts de l'embase. Le connecteur permet donc l'insertion ou l'extraction d'un support de contacts sans frottement avec les contacts du connecteur, ce qui ne nécessite pas d'effort, le bloc mobile entraînant le support de contacts dans son déplacement.In the low position, the groove 19 of the movable block is lower than the groove 14 of the upright 6, so that the contact support 28 can no longer be extracted from the connector, this arrangement of the grooves 14 and 19 ensures mechanical locking; to extract the contact support 28, it is necessary to return the mobile unit to the high position, which eliminates the electrical contacts between the contacts of the contact support and the contacts of the base. The connector therefore allows the insertion or extraction of a contact support without friction with the contacts of the connector, which requires no effort, the movable block driving the contact support in its movement.

La figure 4 représente une autre forme de réalisation d'un connecteur selon l'invention. Le connecteur comporte un socle 35, un bloc fixe 36, un bloc mobile 37, un axe de commande 38.FIG. 4 shows another embodiment of a connector according to the invention. The connector comprises a base 35, a fixed block 36, a movable block 37, a control pin 38.

Le socle 35, en forme de L, comporte une embase 40 munie de contacts 41, identiques aux contacts 5 des figures 1, 2, 3, et une paroi 42 dans laquelle est pratiquée sur la plus grande partie de sa longueur Une rainure 43 qui ne débouche qu'à une extrémité dé ladite paroi ; des trous 58 sont ménagés dans la partie supérieure de ladite paroi 42 pour la fixation du socle. Le bloc fixe 36 comporte une première 44 et une deuxième 45, barre plate, réunies à leurs extrémités par deux montants 46 et 47 ; la première barre plate 44 comporte un talon 48 sur toute sa longueur à l'extérieur de l'ensemble constitué par les barres plates et les montants ; les montants 46 et 47 comportant chacun un trou 49, 49' respectivement, lesquels reçoivent les extrémités de l'axe de commandé 38. Le bloc mobile 37, est un tube de section reetangulaire comportant une paroi supérieure 50 présentant sur toute sa longueur deux talons 51 et 52 ; le bloc mobile vient se loger, avec l'axe de commande 38 introduit dans ladite section rectangulaire, dans le bloc fixe 36, entre les montants 46 et 47, et contre les barres plates 44 et 45, les talons 51 et 52 du bloc mobile étant au-dessus desdites barres plates. L'axe de commande 38 est identique à l'axe de commande 3 des figures 1; 2, 3 et comporte donc des cames 53 près de ses extrémités et sur sa longueur ; lorsque l'axe de commande 38 est engagé dans les trous 49 et 49' du bloc fixe, les cames près des extrémités dudit axe de commande viennent également s'engager partiellement dans un logement ménagé dans les montants 46 et 47 ; un loquet 54 est tixé par une vis 55 à une extrémité de l'axe de cemmande, du côté correspondant du socle 35 ou la rainure 43 ne débouche pas ; l'autre extrémité de l'axe de commande 38 comporte une fente 56 pour la rotation de celui-ci. Une carié de circuit imprimé 39 est fixée par tout moyen connu sur la paroi inférieure 57 du bloc mobile 37 lorsque celui-ci est placé dans le bloc fixe 36. Une face de la carte de circuit imprimé, opposée à la face en contact avec le bloc mobile, comporte, sous ledit bloc mobile, des contacts 65.The base 35, L-shaped, comprises a base 40 provided with contacts 41, identical to the contacts 5 of FIGS. 1, 2, 3, and a wall 42 in which is formed over most of its length A groove 43 which only opens at one end of said wall; holes 58 are provided in the upper part of said wall 42 for fixing the base. The fixed block 36 comprises a first 44 and a second 45, flat bar, joined at their ends by two uprights 46 and 47; the first flat bar 44 has a heel 48 over its entire length outside the assembly formed by the flat bars and the uprights; the uprights 46 and 4 7 each having a hole 49, 49 'respectively, which receive the ends of the controlled axis 38. The movable block 37, is a reetangular section tube having an upper wall 50 having over its entire length two heels 51 and 52; the movable block is housed, with the control pin 38 introduced into said rectangular section, in the fixed block 36, between the uprights 46 and 47, and against the flat bars 44 and 45, the heels 51 and 52 of the movable block being above said flat bars. The control axis 38 is identical to the control axis 3 of Figures 1; 2, 3 and therefore has cams 53 near its ends and along its length; when the control pin 38 is engaged in the holes 49 and 49 'of the fixed block, the cams near the ends of said control pin also partially engage in a housing formed in the uprights 46 and 47; a latch 54 is fixed by a screw 55 at one end of the control axis, on the corresponding side of the base 35 or the groove 43 does not open; the other end of the control shaft 38 has a slot 56 for the rotation thereof. A printed circuit decay 39 is fixed by any known means to the bottom wall 57 of the movable block 37 when the latter is placed in the fixed block 36. One face of the printed circuit board, opposite the face in contact with the movable unit, comprises, under said movable unit, contacts 65.

La figure 5 représente une coupe transversale du connecteur de la figure 4. Le socle 35 est fixé sur un support 62 par des boulons 63 ; l'axe de commande 38 est dans une position telle que, sous l'action des cames 53, le bloc mobile 37 prend une position haute par rapport au bloc fixe 38, les cames 53 aux extrémités de l'axe de commande 38 se déplaçant dans un logement 64 en forme de secteur circulaire ménagé dans les montants 46 et 47 du bloc fixe. Le bloc fixe 36, le bloc mobile 37 et la carte de circuit imprimé 39, constituent un support de contacts et le talon 48 du bloc fixé est Introduit dans la rainure 43 du socle jusqu'à ce qu'il vienne en butée sur l'extrémité de ladite rainure. L'axe de commande 38 est alors tourné et sous l'action de la came 53, le bloc mobile se déplace perpendiculairement à l'embase dans le bloc fixe et prend une position basse représentée figure 6.5 shows a cross section of the connector of Figure 4. The base 35 is fixed on a support 62 by bolts 63; the control axis 38 is in a position such that, under the action of the cams 53, the movable block 37 assumes a high position relative to the fixed block 38, the cams 53 at the ends of the control axis 38 moving in a housing 64 in the form of a circular sector formed in the uprights 46 and 47 of the fixed block. The fixed block 3 6, the movable block 37 and the printed circuit board 39, constitute a contact carrier and the heel 48 of the fixed block is introduced into the groove 43 of the socket until it abuts the end of said groove. The 3-axis control 8 is then rotated under the action of the cam 53, the movable block moves perpendicularly to the base plate in the fixed block and takes a low position shown in FIG 6.

La figure 6 représente le connecteur de la figure 4 vu par son extrémité de gauche, avec coupe partielle des blocs fixe et mobile, le bloc mobile 37 étant en position basse ; la carte de circuit imprimé 39 est pressée contre les contacts 41 de l'embase, ce qui assure les contacts électriques entre les contacts 41 de l'embase et les contacts 65 de ladite carte de circuit imprimé ; le loquet 54 ayant tourné avec l'axe de commande interdit toute extraction du support de contacts, ledit loquet venant alors buter contre l'extrémité de la paroi 42 du socle 35. L'extraction du support de contacts ne peut se faire que si l'axe de commande est tourné de manière à mettre le bloc mobile en position haute, ce qui fait pivoter le loquet 64 et supprime les contacts électriques, le bloc mobile entraînant la carte de circuit imprimé dans son déplacement.6 shows the connector of Figure 4 seen from its left end, with partial section of the fixed and movable blocks, the movable block 37 being in the low position; the printed circuit board 39 is pressed against the contacts 41 of the base, which ensures the electrical contacts between the contacts 41 of the base and the contacts 65 of said printed circuit board; the latch 54 having rotated with the control axis prohibits any extraction of the contact support, said latch then abutting against the end of the wall 42 of the base 35. The extraction of the contact support can only be done if the 'control axis is rotated so as to put the movable block in the high position, which rotates the latch 64 and removes the electrical contacts, the movable block causing the printed circuit board in its movement.

La figure 7 représente schématiquement un support de contacts 70 introduit entre deux connecteurs, 71 et 72, ledit support de contacts ayant des contacts à chaque extrémité ; dans le cas d'un grand nombre de contacts, il est en effet préférable de répartir les contacts sur les deux extrémités du support de contacts, au lieu de les disposer d'un seul côté, ce qui nécessiterait à la fois une carte et un connecteur de plus grandes dimensions.FIG. 7 schematically represents a contact support 70 introduced between two connectors, 71 and 72, said contact support having contacts at each end; in the case of a large number of contacts, it is in fact preferable to distribute the contacts on the two ends of the contact support, instead of having them on one side, which would require both a card and a larger connector.

Les connecteurs 71 et 72 sont soit du type représenté figure 1, soit du type représenté figure 4, l'insertion du support de contacts étant longitudinale.The connectors 71 and 72 are either of the type shown in FIG. 1, or of the type shown in FIG. 4, the insertion of the contact support being longitudinal.

La figure 8 représente l'utilisation d'un connecteur 71 avec une carte de circuit imprimé 73 n'ayant des contacts que d'un seul côté ; pour faciliter le positionnement et l'insertion longitudinale de la carte de circuit imprimé, on utilise, comme cela est classique, une glissière 74 en forme de U dans laquelle glisse la carte de circuit imprimé. Le connecteur 71 est bien entendu soit du type représenté figure 1, soit du type représenté figure 4.FIG. 8 represents the use of a connector 71 with a printed circuit board 73 having contacts only on one side; to facilitate the positioning and the longitudinal insertion of the printed circuit board, a U-shaped slide 74 is used, as is conventional in which the printed circuit board slides. The connector 71 is of course either of the type shown in FIG. 1, or of the type shown in FIG. 4.

La figure 9 représente l'emploi d'un connecteur 71 avec insertion transversale d'un support de contacts tel qu'une carte de circuit imprimé 75. Contrairement à ce qui a été dit lors de la description des figures 1 à 8, où l'insertion du support de contacts s'effectuait longitudinalement par rapport au connecteur, dans cette figure 9 l'insertion est transversale, c'est-à-dire perpendiculaire au connecteur, que celui-ci soit du type de la figure 1 ou de la figure 4. La carte de circuit imprimé 75 glisse entre deux glissières 76 et 77 et est insérée dans la rainure longitudinale 19 du connecteur de la figure 1, ou dans la rainure 43 du socle du connecteur de la figure 4.FIG. 9 represents the use of a connector 71 with transverse insertion of a contact support such as a printed circuit board 75. Contrary to what has been said during the description of FIGS. 1 to 8, where the insertion of the contact support was carried out longitudinally with respect to the connector, in this FIG. 9 the insertion is transverse, that is to say perpendicular to the connector, whether the latter is of the type of FIG. 1 or of the FIG. 4. The printed circuit board 75 slides between two slides 76 and 77 and is inserted into the longitudinal groove 19 of the connector of FIG. 1, or into the groove 43 of the base of the connector of FIG. 4.

Afin d'assurer le verrouillage de la carte de circuit imprimé lorsque les contacts électriques sont établis, la carte de circuit imprimé comporte par exemple des encoches 78 et 79 et le socle du connecteur comporte des ergots 80 et 81.In order to ensure the locking of the printed circuit card when the electrical contacts are established, the printed circuit card comprises for example notches 78 and 79 and the base of the connector comprises lugs 80 and 81.

La figure 10 représente une extrémité du connecteur et de la carte de circuit imprimé de la figure 9, dans cette figure on a représenté un connecteur du type de la figure 1 ; la rainure longitudinale 19 du bloc mobile 2 comporte un chanfrein 82 sur toute sa longueur pour faciliter l'insertion de la carte de circuit imprimé 75 ; lorsque la carte de circuit imprimé est insérée dans la rainure longitudinale, et que le bloc mobile 2 est en position basse, l'ergot 80 de l'embase vient se loger dans l'encoche 78 empêchant l'extraction de la carte de circuit imprimé. Bien entendu, le connecteur peut être du type de la figure 4, et dans ce cas c'est la rainure 43 qui est chanfreinée pour faciliter l'insertion du talon 48 du bloc fixe 36.FIG. 10 represents one end of the connector and of the printed circuit board of FIG. 9, in this figure a connector of the type of FIG. 1; the longitudinal groove 19 of the movable block 2 has a chamfer 82 over its entire length to facilitate the insertion of the printed circuit board 75; when the printed circuit board is inserted in the longitudinal groove, and the movable block 2 is in the low position, the lug 80 of the base is housed in the notch 78 preventing the extraction of the printed circuit board . Of course, the connector can be of the type of FIG. 4, and in this case it is the groove 43 which is chamfered to facilitate the insertion of the heel 48 of the fixed block 36.

Il est également possible d'utiliser trois connecteurs, avec une carte de circuit imprimé ayant des contacts sur trois côtés ; pour cela on dispose un troisième connecteur entre les connecteurs 71 et 72 de la figure 7, l'insertion de la carte de circuit imprimé dans ce troisième connecteur étant transversale, comme représenté figure9, les connecteurs 71 et 72, dans lesquels l'insertion est longitudinale, servant de glissière ; le verrouillage de la carte de circuit imprimé est assuré par les connecteurs 71 et 72.It is also possible to use three connectors, with a printed circuit board having contacts on three sides; for this there is a third connector between the connectors 71 and 72 of FIG. 7, the insertion of the printed circuit board in this third connector being transverse, as shown in FIG. 9, the connectors 71 and 72, in which the insertion is longitudinal, serving as a slide; the locking of the printed circuit board is ensured by connectors 71 and 72.

Les connecteurs décrits et représentés peuvent être utilisés soit horizontalement soit verticalement, comme les connecteurs classiques ; le support de contacts est soit directement une carte de circuit imprimé, soit un « connecteur maie", plat, comme on en utilise avec les connecteurs classiques, fixé à une extrémité d'une carte de circuit imprimé. Un des avantages du connecteur selon l'invention par rapport aux connecteurs connus est de permettre des connexions avec une carte de circuit ayant des contacts soit sur deux côtés opposés, soit sur deux côtés adjacents, soit encore sur trois côtés, les connecteurs étant fixés sur un bâti et l'insertion se faisant en une seule opération.The connectors described and shown can be used either horizontally or vertically, like conventional connectors; the contact support is either directly a printed circuit board or a "flat connector", as used with conventional connectors, fixed to one end of a printed circuit board. One of the advantages of the connector according to the invention with respect to known connectors is to allow connections with a circuit board having contacts either on two opposite sides, or on two adjacent sides, or even on three sides, the connectors being fixed on a frame and the insertion being doing it in one operation.

Les figures 11 et 12 illustrent une variante de réalisation du connecteur décrit dans les figures 1 à 3. Cette variante permet de connecter une carte ayant des contacts sur deux faces opposées.Figures 11 and 12 illustrate an alternative embodiment of the connector described in Figures 1 to 3. This variant allows to connect a card having contacts on two opposite faces.

On retrouve, comme dans la figure 1 un socle 1 comprenant une embase 4 munie de contacts 5 et deux montants 6 et 7 comportant chacun un trou recevant un axe de commande 3. Le bloc mobile 2 de la réalisation des figures 1 à 3 est ici décomposé en 2 parties 2a et 2b ; la partie 2a peut coulisser entre les montants 6 et 7 et la partie 2b coulisse dans la partie 2a.We find, as in Figure 1 a base 1 comprising a base 4 provided with contacts 5 and two uprights 6 and 7 each having a hole receiving a control axis 3. The movable block 2 of the embodiment of Figures 1 to 3 is here broken down into 2 parts 2a and 2b; part 2a can slide between the uprights 6 and 7 and part 2b slides in part 2a.

La carte 28 est cette fois logée dans une rainure 14a de la partie 2a.The card 28 is this time housed in a groove 14a of the part 2a.

La pièce 26 porte des contacts 5b, destinée à coopérer avec la face supérieure de la carte 28 alors que les contacts 5 coopèrent avec la face inférieure de la carte.The part 26 carries contacts 5b, intended to cooperate with the upper face of the card 28 while the contacts 5 cooperate with the lower face of the card.

L'axe 3 porte deux séries de cames : l'une 23a coopère avec la partie 2a, l'autre 23b avec la partie 2b.The axis 3 carries two series of cams: one 23a cooperates with the part 2a, the other 23b with the part 2b.

Lorsque l'axe 3 tourne, il entraîne d'abord par la came 23a, la pièce 2a et le contact s'effectue entre la face inférieure de la carte 28 et les contacts 5.When the axis 3 rotates, it first drives through the cam 23a, the part 2a and the contact takes place between the underside of the card 28 and the contacts 5.

Puis la came 23b agit entraînant la partie 2b et le contact s'effectue entre la face supérieure de la carte 28 et les contacts 5b.Then the cam 23b acts causing the part 2b and the contact takes place between the upper face of the card 28 and the contacts 5b.

Pour obtenir cette succession de déplacements, on a donné, au secteur de la came 23b, une valeur inférieure à celui de la came 23a.To obtain this succession of displacements, the sector of the cam 23b has been given a value lower than that of the cam 23a.

Bien entendu, l'invention n'est pas limitée aux exemples de réalisation décrits et représentés.Of course, the invention is not limited to the embodiments described and shown.
