Description

La présente invention concerne le domaine des connecteurs électriques dits à faible force d'insertion ou à force d'insertion nulle, plus particulièrement à contacts broche/lyre.The present invention relates to the field of electrical connectors said to have low insertion force or zero insertion force, more particularly with pin / lyre contacts.

Pour connecter une nappe de câbles souples sur un support rigide type carte imprimée, les utilisateurs requièrent des connecteurs nécessitant un minimum d'efforts à l'insertion et au verrouillage, ce dernier restant une nécessité première pour parer à toute déconnexion intempestive. Plus généralement, il est recherché des connecteurs permettant de parer à toute déconnexion accidentelle.To connect a ribbon of flexible cables to a typical rigid support printed board, users require connectors requiring a minimum effort at insertion and locking, the latter remaining a primary necessity to counter any untimely disconnection. More generally, connectors are sought after to cover any accidental 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 type carte imprimée et muni à cet effet de contacts à lame avec broches qui sont soudées 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 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 printed-type support and provided for this purpose with blade contacts with pins 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 ensuite 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. Then just 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 ces connecteurs, il peut être intéressant de prévoir un connecteur pouvant 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 these connectors, it it may be interesting to provide a connector that can receive different thickness of cable layers.

Pour résoudre ce problème des variations d'épaisseur, l'embase décrite dans ce brevet américain comprend des lames avec un profil particulier en C, à extrémités décalées formant ainsi deux points de contact, sur le dessus et sur le dessous de la nappe. Les branches du C présentent une certaine souplesse et compensent les variations d'épaisseur. La nappe se déforme en S lorsqu'elle est mince et la nappe reste sensiblement plane lorsqu'elle est épaisse. La pression de contact est obtenue de la même façon dans les deux cas et seuls sont possibles deux points de contact.To solve this problem of variations in thickness, the base described in this American patent comprises blades with a particular C profile, with offset ends thus forming two contact points, on the top and on the bottom of the sheet. The branches of C have a certain flexibility and compensate for variations in thickness. The ply deforms into an S when it is thin and the ply remains substantially flat when it is thick. The contact pressure is obtained in the same way in both cases and only two contact points are possible.

La présente invention propose un connecteur comprenant une embase et une fiche, qui nécessite une très faible force d'insertion et de verrouillage de la fiche dans l'embase, qui génère une excellente liaison électrique, qui comprend des premiers et éventuellement des seconds moyens de verrouillage, qui est simple de fabrication, et qui est d'une manipulation aisée.The present invention provides a connector comprising a base and a plug, which requires a very low insertion and locking force of the plug in the socket, which generates an excellent electrical connection, which includes first and possibly second locking means, which is simple to manufacture, and which is easy to handle.

A cet effet, selon l'invention, le connecteur électrique à faible force d'insertion, comprend une embase munie d'un logement borgne prévu pour recevoir une fiche, cette embase portant des broches de connexion et cette fiche étant reliée à un faisceau de câbles électriques, et se caractérise en ce qu'il est muni de moyens de guidage en translation, notamment comportant au moins une rampe de guidage débouchant dans un trou de verrouillage, trou qui constitue des premiers moyens de verrouillage dits en translation, en coopérant avec au moins une nervure fixe de profil adapté pour prendre une première orientation dans laquelle elle peut être déplacée en translation dans ladite rampe et une seconde orientation dans laquelle elle est immobilisée dans le trou de verrouillage par basculement relatif de la fiche et de l'embase.To this end, according to the invention, the low-force electrical connector insertion, includes a base provided with a blind housing provided for receive a plug, this base carrying connection pins and this plug being connected to a bundle of electric cables, and is characterized in that that it is provided with means for guiding in translation, in particular comprising at minus a guide ramp opening into a locking hole, a hole which constitutes the first locking means known as in translation, in cooperating with at least one fixed rib of profile adapted to take a first orientation in which it can be moved in translation in said ramp and a second orientation in which it is immobilized in the locking hole by relative tilting of the plug and the base.

Ce connecteur électrique comprend aussi des seconds moyens de verrouillage dits en basculement.This electrical connector also includes second means for locking known as tilting.

Selon un agencement particulier, 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 a particular arrangement, 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 , in so that the base and the plug are aligned after locking.

Selon le mode de réalisation préféré, les seconds moyens de verrouillage comprennent une bague montée coulissante sur l'extrémité supérieure du bloc de la fiche et munie de deux pattes latérales de profil et de position adaptés pour pénétrer chacune dans la rainure de la rampe correspondante. Il est prévu de plus des moyens de retenue de cette bague dans les positions active et inactive.According to the preferred embodiment, the second locking means include a sliding ring mounted on the upper end of the block of the plug and fitted with two lateral tabs of suitable profile and position to each enter the groove of the corresponding ramp. It is provided moreover means for retaining this ring in the active positions and inactive.

Selon une application particulière de l'invention, chaque contact électrique de la fiche est un contact à lame de type lyre avec deux branches prévues pour venir au contact de part et d'autre de chaque broche portée par l'embase.According to a particular application of the invention, each contact electric plug is a lyre type blade contact with two branches provided to come into contact on either side of each pin carried by the base.

Selon d'autres caractéristiques particulières de l'invention, il est prévu des agencements particuliers des contacts du connecteur qui permettent de renforcer la liaison électrique et de faciliter les montages des nappes de câbles tout en garantissant la qualité des montages.According to other particular features of the invention, provision is made special arrangements of the connector contacts which allow strengthen the electrical connection and facilitate the mounting of the cable layers while guaranteeing the quality of the assemblies.

L'angle 66 inférieur de chacun des trous qui sert d'appui, est muni d'un congé de rayon r.The lower angle 66 of each of the holes which serves as a support is provided with a fillet of radius r .

La fiche 12 comprend un bloc 68 de forme partiellement conjuguée de celle du logement 22 borgne de l'embase avec deux faces supérieure 69 et inférieure 70 sensiblement parallèles et deux faces 71, 72 latérales de guidage. Ce bloc comprend deux pans a' et b' sur sa face supérieure et un pan unique p' sur sa face inférieure.The plug 12 comprises a block 68 of shape partially conjugate with that of the blind housing 22 of the base with two upper faces 69 and lower 70 substantially parallel and two sides 71, 72 lateral guide. This block comprises two sections a ' and b' on its upper face and a single section p ' on its lower face.

De façon connue, ce bloc 68 comprend une fente 73 de réception d'un faisceau 14 de câbles 16 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. Ces contacts électriques en forme de lyre sont maintenus dans des créneaux 77 ménagés dans ledit bloc, formant un peigne et qui se prolongent autour de ces lames en forme de lyre, en les enveloppant latéralement pour le moins. Cet agencement permet de maintenir un espace régulier entre les lames, de les maintenir rigides pour un bon contact avec les broches et de les isoler électriquement tout en laissant les broches pénétrer pour assurer la liaison électrique. In known manner, this block 68 comprises a slot 73 for receiving a bundle 14 of cables 16 electric. The conductive part of each cable is extends into 74 juxtaposed cells. Each cell has a hole 75 for the passage of an electric contact 76 in the form of a blade, comprising each a foot 78 and a head 80. These electrical contacts in the shape of a lyre are held in slots 77 formed in said block, forming a comb and which extend around these lyre-shaped blades, by wrapping sideways to say the least. This arrangement makes it possible to maintain regular space between the blades, keep them rigid for good contact with the pins and isolate them electrically while leaving them pins penetrate to provide electrical connection.

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.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 penetrate the conductive part of the corresponding cable and ensure the electrical connection. The foot is generally equipped with harpoons which prohibit removing each blade contact from its slot after assembly.

Dans ce mode de réalisation, la tête 80 de chaque contact 76 est en forme de lyre 82, avec deux branches 82-1 et 82-2.In this embodiment, the head 80 of each contact 76 is in lyre shape 82, with two branches 82-1 and 82-2.

Chacune de ces branches présente un profil particulier de type lyre qui permet, comme montré sur la figure 5A, une introduction sans contact entre la broche et les branches en forme de lyre avant basculement et un contact important et multipoints après basculement, comme montré sur les figures 5B et 5C.Each of these branches has a specific lyre type profile which allows, as shown in Figure 5A, a contactless introduction between the lyre-shaped brooch and branches before tipping and contact large and multipoint after failover, as shown in Figures 5B and 5C.

La fiche porte aussi une partie des premiers 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 au plus à celle du plus grand côté 54, 56 du trou 42, 44. L'une des extrémités 92, 94 de chaque nervure est arrondie avec un rayon de courbure égale à r pour coopérer avec le congé 66 prévu en partie inférieure du trou.The card also carries part of the first means 37 for guiding and locking in the form of two ribs 84, 86. Each rib comprises a straight portion 88, 90 of width equal to the width of the ramps the base, close to the sliding clearance and of length equal at most to that of the larger side 54, 56 of hole 42, 44. One of the ends 92, 94 of each rib is rounded with a radius of curvature equal to r to cooperate with the leave 66 provided in the lower part of the hole.

Chaque nervure est munie d'un bossage 96, 98 prévu pour coopérer avec les crans 62, 64 ménagés dans l'embase comme cela sera expliqué ultérieurement.Each rib is provided with a boss 96, 98 intended to cooperate with the notches 62, 64 formed in the base as will be explained later.

Afin de tenir compte de l'épaisseur restante de chaque paroi latérale, la nervure est espacée de la paroi latérale qui la porte.In order to take into account the remaining thickness of each side wall, the rib is spaced from the side wall which carries it.

De plus, l'axe longitudinal de la nervure fait également un angle α avec l'axe longitudinal 66 du bloc 68 dont les quatre faces sont sensiblement parallèles deux à deux si l'on exclut les pans. Quant à l'extrémité du bloc, elle est faiblement arrondie avec un rayon R identique au rayon R du fond 32.In addition, the longitudinal axis of the rib also makes an angle α with the longitudinal axis 66 of the block 68 whose four faces are substantially parallel two by two if we exclude the sides. As for the end of the block, it is slightly rounded with a radius R identical to the radius R of the bottom 32.

L'embase et la fiche sont également équipées de seconds moyens de guidage 70, en l'occurrence deux ailes 100, 102 portées par la fiche et deux rainures 104, 106 ménagées dans l'embase et de profil conjugué pour permettre un positionnement précis. Il convient en effet de limiter le jeu à la pénétration pour que les contacts à lame de type lyre viennent bien, par les deux branches 82-1 et 82-2, de part et d'autre de la broche 18 correspondante.The base and the plug are also equipped with second means of guide 70, in this case two wings 100, 102 carried by the plug and two grooves 104, 106 formed in the base and of conjugate profile for allow precise positioning. It should indeed limit the game to the penetration so that the lyre-type blade contacts come well, through the two branches 82-1 and 82-2, on either side of pin 18 corresponding.

Le connecteur selon la présente invention peut également être complété par des seconds moyens 108 de verrouillage.The connector according to the present invention can also be completed by second locking means 108.

Ces seconds moyens de verrouillage comprennent une bague 110 montée coulissante sur l'extrémité supérieure de la fiche, extrémité qui reste extérieure à l'embase après emboítement.These second locking means comprise a ring 110 sliding mounted on the upper end of the plug, the remaining end external to the base after fitting.

Cette bague comprend deux pattes 112, 114 latérales de profil et de position adaptés pour pénétrer chacune dans la rainure de la rampe 38, 40 correspondante.This ring comprises two tabs 112, 114 lateral in profile and position adapted to penetrate each into the groove of the ramp 38, 40 corresponding.

Cette bague peut prendre deux positions, l'une montrée sur la figure 1A dans laquelle la bague est en position haute, inactive, et l'autre montrée sur la figure 1B dans laquelle la bague est en position basse, active, de verrouillage au basculement, les pattes 112, 114 pénétrant dans les rampes, suivant les flèches.This ring can take two positions, one shown in Figure 1A in which the ring is in the high position, inactive, and the other shown on the Figure 1B in which the ring is in the low, active, locking position on tilting, the legs 112, 114 entering the ramps, according to the arrows.

Selon le mode de réalisation préférentiel retenu, il est aussi prévu des moyens 120 de retenue des seconds moyens de verrouillage dans chacune des positions active et inactive, comportant un double bossage 116, 118 ménagé à l'intérieur de la bague, et à l'extérieur de la fiche, l'ensemble formant un point dur.Depending on the preferred embodiment chosen, provision is also made for means 120 for retaining the second locking means in each of the active and inactive positions, comprising a double boss 116, 118 formed inside the ring, and outside the plug, the assembly forming a hard point.

La mise en place d'un tel connecteur est réalisée ainsi que cela va être expliqué.The installation of such a connector is carried out as will be Explain.

L'embase est considérée comme immobilisée dans le cas présent, les broches 18 faisant saillie dans le logement borgne 22.The base is considered immobilized in this case, the pins 18 protruding into the blind housing 22.

La fiche 12 est insérée dans le logement borgne et dans une première approche, la fiche est guidée en translation verticale par les nervures 84, 86 qui glissent dans les rampes 38 et 40. Le bloc 68 de la fiche est en position inclinée. Sheet 12 is inserted in the blind housing and in a first approach, the plug is guided in vertical translation by the ribs 84, 86 which slide in the ramps 38 and 40. The block 68 of the plug is in position tilted.

Au fur et à mesure de l'introduction du bloc, chaque contact 76 électrique à lame de type lyre vient de part et d'autre de la broche associée par ses branches 82-1 et 82-2, ceci sans contact avec la broche.As the block is introduced, each contact 76 electric lyre type blade comes from either side of the spindle associated by its branches 82-1 and 82-2, this without contact with the spindle.

Les ailes 100 et 102 de la fiche complètent le guidage par coopération avec les rainures 104 et 106 de l'embase.The wings 100 and 102 of the plug complete the guidance by cooperation with the grooves 104 and 106 of the base.

Lorsque la fiche est entièrement emboítée dans l'embase avec l'extrémité du bloc contre le fond 32, le bloc est en appui par une partie de son pan b' contre le pan c de l'embase et par son pan p' sur le pan p de la face d'enfichage.When the plug is fully fitted into the base with the end of the block against the bottom 32, the block is supported by part of its pan b ' against the pan c of the base and by its pan p' on the pan p of the plug-in face.

Chaque nervure 84, 86 est alors au droit du trou 42, 44.Each rib 84, 86 is then in line with the hole 42, 44.

Pour obtenir le montage définitif, le bloc 68 de la fiche est manoeuvré par basculement suivant la flèche de la figure 5A, c'est-à-dire pour que l'axe 66 longitudinal du bloc soit confondu avec l'axe longitudinal de l'embase, l'angle α devenant nul.To obtain the final assembly, the block 68 of the plug is operated by tilting according to the arrow in FIG. 5A, that is to say so that the longitudinal axis 66 of the block is coincident with the longitudinal axis of the base, angle α becoming zero.

Le bossage 96, 98 de chaque nervure vient s'encliqueter avec le cran 62, 64 correspondant de la face 28, 30 latérale de l'embase. Cet encliquetage, par son élasticité, permet à l'opérateur de sentir la manoeuvre et de percevoir que le point de verrouillage est atteint.The boss 96, 98 of each rib engages with the notch 62, 64 corresponding to the lateral face 28, 30 of the base. This snap, by its elasticity, allows the operator to feel the maneuver and to perceive that the locking point has been reached.

Chaque contact 76 électrique vient en contact par ses branches avec la broche 18 correspondante comme montré sur les figures 5B et 5C.Each electrical contact 76 comes into contact by its branches with the corresponding pin 18 as shown in Figures 5B and 5C.

Le bloc 68 se trouve alors en appui par les pans a' et b' de sa face supérieure sur les pans a et b de l'embase, ce qui représente un appui stable, d'autant que la face arrière est en appui par son pan p' sur le pan q de l'embase.The block 68 is then supported by the sides a ' and b' of its upper face on the sides a and b of the base, which represents a stable support, all the more so as the rear face is supported by its pan p ' on pan q of the base.

Les premiers moyens de verrouillage interdisent le retrait de la fiche hors de l'embase. Néanmoins, la fiche peut être ramenée en position inclinée par basculement inverse, moyennant un effort réduit pour dépasser le point dur constitué par les couples bossage/cran, ces couples assurant un frein au basculement intempestif, notamment engendré par des vibrations ou des chocs légers.The first locking means prevent the withdrawal of the plug from of the base. However, the plug can be returned to the inclined position by reverse tilt, with reduced effort to overcome the hard point constituted by the boss / notch couples, these couples ensuring a brake on inadvertent tilting, in particular caused by vibrations or light shocks.

Aussi est-il utile d'équiper le présent connecteur des seconds moyens 108 de verrouillage qui interdisent ce mouvement de basculement en retour. Il suffit de manoeuvrer la bague 110 coulissante de l'extrémité supérieure de la fiche vers l'embase, dans le sens de la flèche 34 d'introduction de la fiche dans l'embase.It is therefore useful to equip this connector with second locking means 108 which prohibit this tilting movement in return. It suffices to operate the sliding ring 110 from the end top of the plug towards the base, in the direction of arrow 34 for inserting the plug into the socket.

Chaque patte 112, 114 pénètre alors dans la rampe 38, 40 correspondante ainsi que cela est visible sur la figure 1B et la vue en section de la figure 2.Each leg 112, 114 then enters the ramp 38, 40 corresponding as seen in Figure 1B and the section view in Figure 2.

On constate que la fiche est néanmoins démontable par mise en oeuvre successive des étapes inverses. Par contre, toute déconnexion intempestive est interdite sans intervention volontaire.We note that the plug is nevertheless removable by implementation successive reverse steps. However, any untimely disconnection is prohibited without voluntary intervention.

On peut modifier le système d'encliquetage avec un couple bossage/cran disposé entre la nervure et la face latérale en vis à vis par une nervure comme décrit précédemment en le remplaçant par un bossage ou un cran en tout endroit de la nervure à partir du moment où on ménage en vis à vis dans l'embase un cran ou un bossage conjugué.You can modify the locking system with a couple boss / notch disposed between the rib and the lateral face opposite by a rib as described above by replacing it with a boss or a notch in any part of the rib from the moment we clean opposite screw a notch or a conjugate boss in the base.
