The base and the plug are connected to a flexible circuit (14, 16) of the type comprising a layer of electrical cables (18, 20). The electrical connector comprises sliding introduction guide means (38, 40) and means (84, 86) for locking in translation to permit a first orientation in which the plug can be displaced in translation and a second orientation in which the plug is immobilized by relative swinging of the plug and the base.

Description

La présente invention concerne le domaine des connecteurs électriques dits à faible force d'insertion ou à force d'insertion nulle, plus particulièrement applicable aux circuits dits souples.The present invention relates to the field of electrical connectors said to have low insertion force or zero insertion force, more particularly applicable to so-called flexible circuits.

Pour connecter des nappes de câbles souples, les utilisateurs requièrent des connecteurs avec un minimum d'efforts à l'insertion et au verrouillage, celui-ci étant de type verrouillage en translation et restant une nécessité première pour parer à toute déconnexion intempestive.To connect flexible cable layers, users require connectors with minimal effort at insertion and locking, this being of the translational locking type and remaining a necessity first to prevent any untimely disconnection.

On connaít par exemple un connecteur à force d'insertion nulle décrit dans le brevet US-A-4 718 859, prévu pour recevoir une nappe de câbles. Un tel connecteur comprend deux blocs :

  • un bloc fixe, généralement rapporté sur un support et muni à cet effet de contacts à lame avec broche qui sont soudés à ce support, et
  • un bloc mobile qui coopère avec le bloc fixe pour immobiliser les câbles de la nappe et assurer le contact entre les câbles de cette nappe et les lames, ceci en ne nécessitant aucun effort d'insertion de la nappe.
We know for example a connector with zero insertion force described in US-A-4,718,859, designed to receive a cable ply. Such a connector comprises two blocks:
  • a fixed block, generally attached to a support and provided for this purpose with blade contacts with a pin which are welded to this support, and
  • a movable block which cooperates with the fixed block to immobilize the cables of the sheet and ensure contact between the cables of this sheet and the blades, this requiring no effort to insert the sheet.

Le bloc mobile est monté sur le bloc fixe par un déplacement en translation, des moyens de guidage assurant un positionnement adapté des deux parties. La nappe est ensuite insérée entre les deux blocs. Il suffit alors de faire pivoter le bloc mobile par rapport au bloc fixe pour assurer un plaquage d'une partie des lames sur les câbles, assurant ainsi la liaison électrique. Le verrouillage est assuré simultanément puisque tout déplacement en translation du bloc mobile par rapport au bloc fixe est interdit.The movable block is mounted on the fixed block by a displacement in translation, guide means ensuring suitable positioning of the two parts. The tablecloth is then inserted between the two blocks. It is enough then rotate the movable block relative to the fixed block to ensure plating part of the blades on the cables, thus ensuring the connection electric. Locking is ensured simultaneously since any movement in translation of the movable block relative to the fixed block is prohibited.

Le problème résolu dans ce brevet est celui des variations d'épaisseur des différentes nappes à insérer dans ce connecteur. En effet, ces variations engendrent des pertes de force de pression des broches du bloc fixe sur les câbles de la nappe, sauf à réaliser différents modèles, chacun applicable à un type de nappe. Compte tenu du prix de vente très faible de tels connecteurs, il peut être intéressant de prévoir un même connecteur permettant de recevoir différentes épaisseurs de nappes de câbles.The problem solved in this patent is that of thickness variations different layers to insert into this connector. Indeed, these variations cause losses of pressure force of the pins of the fixed block on the ribbon cables, except when making different models, each applicable to one type of tablecloth. Given the very low selling price of such connectors, it may be interesting to provide the same connector for receiving different thicknesses of cable layers.

Pour résoudre ce problème, les lames de l'embase décrites dans ce document de l'art antérieur ont un profil particulier en C à extrémités décalées formant ainsi deux points de contact décalés, sur le dessus et sur le dessous de la nappe, avec une butée de mise en pression portée par le bloc mobile qui assure une déformation en S de la nappe lorsqu'elle est mince, en sorte de la mettre en contact en deux points.To solve this problem, the base plates described in this document of the prior art have a particular C profile with offset ends, thus forming two offset contact points, on the top and on the bottom of the sheet, with a pressurization stop carried by the movable block which provides an S- shaped deformation of the sheet when it is thin, so as to bring it into contact at two points.

Lorsque la nappe est épaisse, la pression de contact est obtenue de la même façon mais la nappe reste sensiblement plane.When the sheet is thick, the contact pressure is obtained from the same way but the sheet remains substantially flat.

La mise en oeuvre d'un tel connecteur est réalisée successivement par mise en place du bloc mobile sur le bloc fixe, par introduction de la nappe puis par rotation du bloc mobile par rapport au bloc fixe, ce qui a pour effet d'assurer la mise en pression des câbles de la nappe sur les lames à broche de l'embase, notamment lorsque la nappe est mince.The implementation of such a connector is carried out successively by installation of the movable block on the fixed block, by introduction of the sheet then by rotation of the movable block relative to the fixed block, which has the effect ensuring the pressurization of the ribbon cables on the spindle blades of the base, especially when the sheet is thin.

La présente invention a pour objet un connecteur pour relier deux nappes de câbles ou une nappe de câbles et un faisceau de câbles dont les éléments ont des formes simples et dépouillées visant à permettre une mise en contact et un verrouillage simultanés, des fabrications à faible prix de revient tout en offrant les fonctionnalités recherchées et notamment une force d'insertion réduite, une fiabilité de contact, un essuyage au point de contact lors de la connexion pour une des variantes, et une absence de transmission des vibrations dans une autre des variantes.The present invention relates to a connector for connecting two cables or a cable and a bundle of cables whose elements have simple and uncluttered forms aimed at allowing a setting simultaneous contact and locking, low cost manufacturing while offering the desired features and in particular a strength reduced insertion, contact reliability, wiping at the point of contact when connecting for one of the variants, and no transmission vibrations in another variant.

  • la fiche comprend une face supérieure et une face inférieure de laquelle font saillie les contacts électriques, ces deux faces étant sensiblement parallèles et prévues pour coopérer avec les parois d'enfichage et d'appui et deux faces latérales, chacune susceptible de porter une nervure.

  • the plug comprises an upper face and a lower face from which the electrical contacts project, these two faces being substantially parallel and designed to cooperate with the plug-in and support walls and two lateral faces, each capable of carrying a rib.

Selon les modes de réalisation, la nappe de câbles de l'embase est disposée contre la paroi d'appui du logement borgne et la face inférieure de la fiche est en vis à vis de cette paroi d'appui, ou inversement.According to the embodiments, the cable ply of the base is disposed against the support wall of the blind housing and the underside of the plug faces this bearing wall, or vice versa.

Selon un agencement retenu dans l'invention, la nervure de la fiche a une largeur égale à la largeur de la rampe de l'embase et son axe longitudinal est incliné par rapport au plan des faces inférieure et supérieure de la fiche d'un angle α, en sorte que l'embase et la fiche sont alignées après verrouillage.According to an arrangement adopted in the invention, the rib of the plug has a width equal to the width of the ramp of the base and its longitudinal axis is inclined relative to the plane of the lower and upper faces of the plug by an angle α , so that the base and the plug are aligned after locking.

Sur les figures 1A, 1B, 1C et 2A, 2B et 2C, on a représenté un premier mode de réalisation d'un connecteur comprenant une embase 10 et une fiche 12, respectivement rapportée à l'extrémité d'un circuit souple 14 et 16 composé d'une nappe et/ou d'un faisceau de câbles électriques 18 et 20.In Figures 1A, 1B, 1C and 2A, 2B and 2C, there is shown a first embodiment of a connector comprising a base 10 and a plug 12, respectively attached to the end of a flexible circuit 14 and 16 composed of a ribbon cable and / or a bundle of electric cables 18 and 20.

Selon ce premier mode de réalisation, l'embase comprend un logement 22 borgne de réception de la fiche.According to this first embodiment, the base comprises a housing 22 blind for receiving the plug.

Ce logement 22 comprend :

  • une paroi 24 d'enfichage,
  • une paroi 26 d'appui, opposée à la paroi d'enfichage,
  • deux parois 28 et 30 latérales de guidage, seule la paroi 28 étant visible, l'autre paroi étant en vis à vis, et
  • un fond 32.
This housing 22 includes:
  • a wall 24 for plugging in,
  • a support wall 26, opposite the plug wall,
  • two lateral guide walls 28 and 30, only the wall 28 being visible, the other wall being opposite, and
  • a background 32.

La paroi 24 d'enfichage est inclinée d'un angle α, de l'ordre de 10 à 20°, par rapport à la direction d'introduction de la fiche 12, représentée par la flèche 34. De plus, cette paroi d'enfichage est reliée au fond par un congé faisant un arc de cercle de rayon R.The plug-in wall 24 is inclined at an angle α , of the order of 10 to 20 °, relative to the direction of insertion of the plug 12, represented by the arrow 34. In addition, this wall of plugging is connected to the bottom by a fillet making an arc of radius R.

La paroi 26 d'appui est parallèle à la direction d'introduction de la fiche et porte sur une partie de sa surface les câbles 18 dénudés de la nappe 14 correspondante. Une butée 36 permet de limiter la pénétration des câbles et d'assurer un positionnement optimal.The support wall 26 is parallel to the direction of insertion of the plug and carries on a part of its surface the cables 18 stripped of the sheet 14 corresponding. A stop 36 makes it possible to limit the penetration of the cables and ensure optimal positioning.

Chacune des parois latérales 28 et 30 est munie de moyens 37 de guidage et de verrouillage, comportant deux rampes 38, 40 de guidage, chacune sous forme d'une rainure ménagée dans le plan de la paroi et de deux trous 42, 44, pour des raisons évidentes de symétrie et de stabilité. L'une 46, 48 des extrémités de chacune des rampes est débouchante au bord du logement 22 borgne tandis que l'autre 50, 52 des extrémités est débouchante vers le bas dans le trou 42, 44 correspondant.Each of the side walls 28 and 30 is provided with means 37 for guiding and locking, comprising two ramps 38, 40 for guiding, each in the form of a groove in the plane of the wall and two holes 42, 44, for obvious reasons of symmetry and stability. One 46, 48 of the ends of each of the ramps opens out at the edge of the housing 22 blind while the other 50, 52 of the ends is through down into the corresponding hole 42, 44.

Les trous 42, 44 ont un profil particulier, sensiblement en forme de triangle rectangle. Chaque grand côté 54, 56 de l'angle droit est aligné avec le bord de la rampe 38, 40 correspondante, qui est du côté de la paroi 24 d'enfichage.The holes 42, 44 have a particular profile, substantially in the form of rectangle triangle. Each large side 54, 56 of the right angle is aligned with the edge of the corresponding ramp 38, 40, which is on the side of the wall 24 plug-in.

Chaque petit côté 58, 60 est d'une longueur supérieure à la largeur de la rainure correspondante constituant la rampe. Chaque petit côté comprend de plus un bossage 62, 64 de verrouillage, en saillie dans le trou 42, 44 correspondant.Each short side 58, 60 is longer than the width of the corresponding groove constituting the ramp. Each small side includes in addition a locking boss 62, 64, projecting into the hole 42, 44 corresponding.

Hormis l'angle droit, les deux autres angles sont munis d'un congé, d'un même rayon r, dans le cas présent.Apart from the right angle, the other two angles are provided with a leave, of the same radius r , in the present case.

Le fond 32 est muni d'une fente 66 débouchante, à travers laquelle le circuit souple est susceptible de passer.The bottom 32 is provided with a through slot 66, through which the flexible circuit is likely to pass.

La fiche 12 comprend un bloc 68 de forme partiellement conjuguée de celle du logement 22 borgne de l'embase et dont les faces supérieure 69 et inférieure 70 sont sensiblement parallèles, avec deux faces 71, 72 latérales de guidage.Sheet 12 includes a block 68 of partially conjugated form of that of the housing 22 blind of the base and whose upper faces 69 and lower 70 are substantially parallel, with two lateral faces 71, 72 of guidance.

De façon connue, ce bloc 68 comprend une fente 73 de réception d'un circuit souple 16 comprenant un faisceau de câbles 20 électriques. La partie conductrice de chaque câble se prolonge dans des alvéoles 74 juxtaposés. Chaque alvéole est muni d'un trou 75 de passage d'un contact 76 électrique en forme de lame, comportant chacun un pied 78 et une tête 80, et maintenu dans des créneaux 77 ménagés dans ledit bloc. Chaque contact 76 peut prendre deux positions l'une, avant montage, dans laquelle le pied 78 du contact est en dehors de l'alvéole et l'autre, après montage, dans laquelle le pied 78 du contact vient en saillie dans l'alvéole 74 pour pénétrer dans la partie conductrice du câble correspondant et assurer la liaison électrique. Le pied est généralement équipé de harpons qui interdisent le retrait de chaque contact à lame hors de son créneau après montage. In known manner, this block 68 comprises a slot 73 for receiving a flexible circuit 16 comprising a bundle of electric cables 20. The part conductor of each cable extends into 74 juxtaposed cells. Each cell is provided with a hole 75 for passage of an electrical contact 76 blade-shaped, each having a foot 78 and a head 80, and held in slots 77 provided in said block. Each contact 76 can take two positions, one, before mounting, in which the foot 78 of the contact is outside the socket and the other, after mounting, in which the foot 78 of the contact protrudes into the socket 74 to enter the conductive part of the corresponding cable and ensure the electrical connection. The foot is generally equipped with harpoons which prohibit the removal of each blade contact outside its slot after mounting.

Dans ce mode de réalisation, la tête 80 de chaque contact 76 est en forme de crosse 82 dont l'extrémité libre est linéaire, ce qui permet de constituer un effet de rappel.In this embodiment, the head 80 of each contact 76 is in form of butt 82 whose free end is linear, which allows constitute a reminder effect.

La fiche porte aussi une partie des moyens 37 de guidage et de verrouillage sous forme de deux nervures 84, 86. Chaque nervure comprend une partie 88, 90 rectiligne de largeur égale à la largeur des rampes de l'embase, au jeu de coulissement près, et de longueur égale à celle du plus grand côté 54, 56 du trou 42, 44. Les deux extrémités 92, 94; 96, 98 de chaque nervure sont arrondies avec un rayon de courbure égale à r, comme pour les congés des angles des trous.The plug also carries part of the means 37 for guiding and locking in the form of two ribs 84, 86. Each rib comprises a rectilinear part 88, 90 of width equal to the width of the ramps of the base, apart from the sliding clearance , and of length equal to that of the longest side 54, 56 of the hole 42, 44. The two ends 92, 94; 96, 98 of each rib are rounded with a radius of curvature equal to r , as for the leaves of the angles of the holes.

De plus, l'axe longitudinal de la nervure fait également un angle α avec l'axe longitudinal du bloc 68 dont les quatre faces sont sensiblement parallèles deux à deux. Quant à l'extrémité du bloc, elle est arrondie avec un rayon R identique au rayon R du congé entre la paroi 24 d'enfichage et le fond 32. Un tel connecteur est mis en service de la façon suivante.In addition, the longitudinal axis of the rib also forms an angle α with the longitudinal axis of the block 68, the four faces of which are substantially parallel in pairs. As for the end of the block, it is rounded with a radius R identical to the radius R of the leave between the wall 24 for plugging in and the bottom 32. Such a connector is put into service in the following manner.

Une fois les circuits souples et autres faisceaux de câbles connectés sur l'embase et la fiche, la fiche est présentée comme indiqué sur les figures 1A et 2A, c'est à dire, l'axe longitudinal de la nervure parallèle à la direction d'introduction indiquée par la flèche 34. De ce fait, le bloc est incliné d'un angle α si bien que la face supérieure est parallèle à la paroi 24 d'enfichage. La nervure est positionnée dans la rampe correspondante, ce qui permet, sans effort, d'enfoncer la fiche dans l'embase par translation, jusqu'à ce que le bloc vienne en appui sur la paroi d'enfichage, l'extrémité du bloc étant alors en contact avec le fond 32 du logement borgne de l'embase. Plus particulièrement, l'extrémité du bloc coopère avec le congé de rayon R ménagé entre la paroi d'enfichage et le fond. On est alors dans la position représentée sur les figures 1B et 2B.Once the flexible circuits and other bundles of cables are connected to the base and the plug, the plug is presented as shown in FIGS. 1A and 2A, that is to say, the longitudinal axis of the rib parallel to the direction d 'introduction indicated by arrow 34. Therefore, the block is inclined at an angle α so that the upper face is parallel to the wall 24 of insertion. The rib is positioned in the corresponding ramp, which allows, without effort, to push the plug into the base by translation, until the block comes to bear on the plug wall, the end of the block then being in contact with the bottom 32 of the blind housing of the base. More particularly, the end of the block cooperates with the radius leave R formed between the plug wall and the bottom. We are then in the position shown in FIGS. 1B and 2B.

Pour arriver dans la position représentée sur les figures 1C et 2C, il faut faire basculer la fiche par rapport à l'embase suivant la flèche F, manoeuvre qui est également réalisée avec un très faible effort et avec une bonne sensation de verrouillage, grâce aux bossages de verrouillage .To reach the position shown in FIGS. 1C and 2C, the plug must be tilted relative to the base according to arrow F , an operation which is also carried out with very little effort and with a good feeling of locking, thanks to the locking bosses.

Cette action de basculement a plusieurs conséquences. This tipping action has several consequences.

Tout d'abord, la partie rectiligne 82 de la tête 80 en forme de crosse de chaque contact 76 à lame de la fiche vient en contact par pression avec les conducteurs 18 de la nappe 14 de l'embase, ceci par l'élasticité engendrée par la crosse.First of all, the rectilinear part 82 of the head 80 in the form of a butt of each contact 76 with blade of the plug comes into contact by pressure with the conductors 18 of the ply 14 of the base, this by the elasticity generated by the Crosse.

Ensuite, chaque nervure 84, 86 pivote dans le trou 42, 44 correspondant et vient se bloquer dans ce même trou, de l'autre côté du bossage 62, 64 de verrouillage qui constitue un léger point dur. La fiche 12 a son axe longitudinal et sa face inférieure 70 parallèle à la paroi 26 d'appui de l'embase tandis que l'axe longitudinal de la nervure est incliné d'un angle α par rapport à la direction d'introduction. De ce fait, chaque nervure est bloquée dans le trou correspondant, interdisant toute extraction par translation de la fiche hors de l'embase.Then, each rib 84, 86 pivots in the corresponding hole 42, 44 and is blocked in this same hole, on the other side of the locking boss 62, 64 which constitutes a slight hard point. The plug 12 has its longitudinal axis and its lower face 70 parallel to the support wall 26 of the base while the longitudinal axis of the rib is inclined at an angle α relative to the direction of introduction. Therefore, each rib is blocked in the corresponding hole, preventing any extraction by translation of the plug from the base.

On note que, dans ce mode de réalisation, la zone élastique d'appui des contacts à lames sur le circuit souple permet de localiser la pression de contact au niveau de chacun des points de connexion électrique. On note aussi que cet appui élastique évite la transmission des vibrations dans la lame et donc les mouvements du pied par décrochage des harpons de maintien par rapport au bloc.Note that, in this embodiment, the elastic support zone of the reed contacts on the flexible circuit makes it possible to locate the pressure of contact at each of the electrical connection points. We notice also that this elastic support prevents the transmission of vibrations in the blade and therefore the movements of the foot by unhooking the harpoons by report to the block.

Sur les figures 3A, 3B et 3C, on a représenté un premier mode de réalisation de la fixation du circuit souple 14 sur l'embase.In FIGS. 3A, 3B and 3C, there is shown a first mode of making the flexible circuit 14 on the base.

Le circuit souple comprend comme montré sur la figure 3C, deux oreilles 100, 102 dans lesquelles sont ménagés deux trous 104, 106 prévus pour coopérer avec des pions 108, 110 de maintien et de positionnement, solidaires d'une platine 112. Cette platine comprend deux retours 114, 116 avec des trous 118, 120 qui coopèrent avec des plots venus de fabrication avec l'embase, tels que 122, seul visible. Cette platine est de forme adaptée pour s'intégrer dans l'embase.The flexible circuit comprises, as shown in FIG. 3C, two ears 100, 102 in which are provided two holes 104, 106 provided to cooperate with pins 108, 110 for holding and positioning, integral with a plate 112. This plate includes two returns 114, 116 with holes 118, 120 which cooperate with studs from manufacturing with the base, such as 122, only visible. This plate is of adapted shape to fit into the base.

Une autre variante de montage du circuit souple est représentée sur les figures 4A, 4B et 4C. Dans ce cas, la fixation est extérieure avec un double effet ressort. En effet, le circuit souple comprend deux oreilles 122, 124 dans lesquelles sont ménagés deux trous 126, 128 prévus pour coopérer avec des pions 130, 132, de maintien et de positionnement solidaires d'une platine 134. Cette platine comprend deux retours 136, 138 avec des trous 140, 142 qui coopèrent avec des plots venus de fabrication avec l'embase, tels que 144, seul visible. L'embase est en outre munie d'une fente 146, en lieu et place de la fente 66 ménagée dans le fond du logement borgne 22. Le circuit souple est ainsi introduit par cette fente, pour une partie dépassante, de longueur adaptée, la nappe faisant saillie dans le logement borgne, sensiblement parallèlement à la paroi d'appui.Another mounting variant of the flexible circuit is shown on the Figures 4A, 4B and 4C. In this case, the attachment is external with a double spring effect. Indeed, the flexible circuit includes two ears 122, 124 in which are formed two holes 126, 128 provided to cooperate with pins 130, 132, holding and positioning integral with a plate 134. This plate includes two returns 136, 138 with holes 140, 142 which cooperate with studs coming from manufacture with the base, such as 144, only visible. The base is further provided with a slot 146, in instead of the slot 66 formed in the bottom of the blind housing 22. The flexible circuit is thus introduced through this slot, for an protruding part, of suitable length, the tablecloth protruding into the blind housing, substantially parallel to the support wall.

La représentation des figures 5A, 5B et 5C permet d'apprécier la forme extérieure de la fiche et de l'embase et de montrer une variante de réalisation avec des contacts à lames pleines.The representation of FIGS. 5A, 5B and 5C makes it possible to appreciate the shape outside of the plug and socket and show an alternative embodiment with solid reed contacts.

Dans ce cas, les éléments identiques portent les mêmes références que sur les figures 1A, 1B et C; 2A, 2B et 2C.In this case, identical elements have the same references as in Figures 1A, 1B and C; 2A, 2B and 2C.

La différence sur la fiche se situe principalement au droit de la tête 80 du contact 76 électrique en forme de lame. La crosse élastique est supprimée au profit d'une tête pleine, donc rigide. La tête présente une extrémité arrondie avec un rayon de courbure R, pour simplifier la fabrication et assurer une liaison électrique de qualité.The difference on the plug is mainly to the right of the head 80 of the electrical contact 76 in the form of a blade. The elastic stock is eliminated in favor of a full head, therefore rigid. The head has a rounded end with a radius of curvature R , to simplify manufacture and ensure a quality electrical connection.

La différence sur l'embase est la position du circuit souple 14 qui est introduit par la fente 66 du fond, mais qui est positionné sur la paroi d'enfichage, une fente 66-1 borgne supplémentaire est ménagée dans cette paroi pour assurer un bon maintien de ce circuit. De plus, il est prévu un autre congé de rayon R entre le fond 32 et la paroi d'appui.The difference on the base is the position of the flexible circuit 14 which is introduced through the slot 66 at the bottom, but which is positioned on the plug-in wall, an additional blind slot 66-1 is provided in this wall to ensure good maintenance of this circuit. In addition, another radius R leave is provided between the bottom 32 and the support wall.

La mise en place de la fiche dans l'embase est strictement identique aux modes précédents de réalisation, moyennant un retournement de 180° de la fiche, les nervures étant orientées de façon adéquate pour coopérer avec les trous associés. En effet, la face supérieure 69 est maintenant en vis à vis de la paroi 26 d'appui de l'embase.The installation of the plug in the socket is strictly identical to the previous embodiments, by means of a 180 ° reversal of the plug, the ribs being oriented adequately to cooperate with the associated holes. Indeed, the upper face 69 is now facing the wall 26 for supporting the base.

On note un effet supplémentaire dit d'essuyage puisque, lors de l'introduction de la fiche, la tête de chaque contact 76 électrique est amenée au contact du câble dénudé correspondant du circuit souple, puis lors du mouvement de basculement de la fiche par rapport à l'embase, la tête 80 de chaque contact 76 électrique vient frotter sur le câble et assurer ainsi un contact électrique amélioré.There is an additional effect known as wiping since, during introduction of the plug, the head of each electrical contact 76 is brought in contact with the corresponding bare cable of the flexible circuit, then during tilting movement of the plug relative to the base, the head 80 of each electrical contact 76 rubs on the cable and thus ensures a improved electrical contact.

La fiche et l'embase sont ensuite solidarisées comme dans les modes précédents de réalisation.The plug and the base are then secured as in the modes previous work.

Dans l'ensemble des modes de réalisation, la fiche et l'embase se trouvent alignées après verrouillage, en position de travail, ce qui est préférable, l'insertion s'effectuant par une translation, la fiche et l'embase faisant un angle α . Les mêmes fonctions sont obtenues avec une position d'introduction dans laquelle la fiche et l'embase sont alignées et une position verrouillée avec ces deux éléments faisant un angle α.In all of the embodiments, the plug and the base are aligned after locking, in the working position, which is preferable, the insertion being effected by a translation, the plug and the base making an angle. α . The same functions are obtained with an insertion position in which the plug and the base are aligned and a locked position with these two elements making an angle α .

De la même façon, selon une variante comprise dans la présente invention, il est possible de prévoir les bossages 62, 64 de verrouillage sur la nervure et un creux ménagé dans le petit côté du trou 42, 44 associé, prévu pour recevoir chacun, un des bossages. Les bossages pourraient aussi être portés latéralement par la nervure ou par la paroi du logement borgne avec un creux en vis à vis.Similarly, according to a variant included in this invention, it is possible to provide the locking bosses 62, 64 on the rib and a hollow formed in the short side of the associated hole 42, 44, provided to receive each one of the bosses. The bosses could also be carried laterally by the rib or by the blind housing wall with a hollow opposite.

Le connecteur, selon un perfectionnement de la présente invention, peut être muni de seconds moyens de verrouillage. Ces seconds moyens de verrouillage assurent l'immobilisation de la fiche par rapport à l'embase dans le cadre du basculement. Ces seconds moyens comprennent une bague 148 montée coulissante sur l'extrémité supérieure du bloc 68 de la fiche et munie de deux pattes 150, 152 latérales de profil et de position adaptés pour pénétrer chacune dans la rainure de la rampe 38, 40 correspondante.The connector, according to an improvement of the present invention, can be provided with second locking means. These second means of locking ensure the immobilization of the plug relative to the base in the tilting frame. These second means include a ring 148 sliding mounted on the upper end of block 68 of the plug and provided two lateral legs 150, 152 of profile and position adapted for each enter the groove of the corresponding ramp 38, 40.

Comme cela est indiqué sur les figures 1A, B, C et 2A, B, C, la bague est en position haute lors des manoeuvres d'insertion et de basculement et après basculement, la bague est abaissée suivant la flèche F', pour faire pénétrer les pattes dans les rainures correspondantes, ce qui assure un anti-basculement de la fiche par rapport à l'embase, ce qui interdit donc tout retrait en translation de la fiche par rapport à l'embase et par conséquent la déconnexion.As indicated in FIGS. 1A, B, C and 2A, B, C, the ring is in the high position during the insertion and tilting operations and after tilting, the ring is lowered according to the arrow F ' , to make penetrate the tabs in the corresponding grooves, which ensures an anti-tilting of the plug relative to the base, which therefore prohibits any withdrawal in translation of the plug relative to the base and therefore disconnection.
