Description

La présente invention vise des perfectionnements aux organes de contact électrique femelles.The present invention relates to improvements to female electrical contact members.

On connaît des organes de contact électrique femelles présentant un corps en U avec une âme et deux ailes, et pourvu à une extrémité de moyens pour le branchement d'au moins un conducteur électrique, tandis que l'autre extrémité comporte deux barrettes de contacts prolongeant les ailes, lesdites barrettes étant protégées par des languettes s'étendant sur toute leur longueur du côté de la face externe correspondante.There are known female electrical contact members having a U-shaped body with a core and two wings, and provided at one end with means for the connection of at least one electrical conductor, while the other end comprises two contact strips extending the wings, said bars being protected by tabs extending over their entire length on the side of the corresponding external face.

Les barrettes de contacts, lorsqu'on engage un organe mâle, par exemple, un barreau méplat ou un circuit imprimé, tendent à s'écarter l'une de l'autre en pinçant ledit organe mâle. Si, ce dernier présente une section relativement épaisse, les extrémités libres des barrettes portent contre les languettes de sorte que l'insertion peut demander un effort important, de plus et il peut se produire une déformation des barrettes, le cambrage étant alors modifié et l'organe mâle risquant de ne plus être assez pincé.The contact strips, when engaging a male member, for example, a flat bar or a printed circuit, tend to move away from one another by pinching said male member. If, the latter has a relatively thick section, the free ends of the bars bear against the tabs so that the insertion may require significant effort, moreover and there may be a deformation of the bars, the bending being then modified and the male organ may not be pinched enough.

Un des buts de la présente invention est de remédier à cet inconvénient.One of the aims of the present invention is to remedy this drawback.

Les perfectionnements, selon l'invention, visent des organes de contact électrique femelles du type formé d'un corps réalisé en une matière bonne conductrice de l'électricité, ledit corps étant découpé et plié pour affecter la forme d'un U avec une âme et deux ailes, une extrémité dudit corps étant conformée pour présenter des moyens pour sa fixation à un conducteur électrique, tandis qu'à son autre extrémité les ailes du U sont prolongées, d'une part, par deux barrettes de contacts destinées à enserrer élastiquement un organe de contact mâle correspondant tel qu'un circuit imprimé ou un barreau méplat, et d'autre part à leur extrémité libre par une languette s'étendant sur toute la longueur de la barrette de contact correspondante et pliée pour être disposée du côté de la face externe de ladite barrette de contact correspondante, lesdits perfectionnements étant caractérisés en ce que les extrémités libres des barrettes de contacts comportent chacune un ergot, tandis que les languettes présentent chacune une lumière disposée de manière à recevoir l'ergot correspondant.The improvements according to the invention relate to female electrical contact members of the type formed by a body made of a material which is good conductor of electricity, said body being cut and folded to take the shape of a U with a core. and two wings, one end of said body being shaped to present means for fixing it to an electrical conductor, while at its other end the wings of the U are extended, on the one hand, by two contact strips intended to clamp elastically a corresponding male contact member such as a printed circuit or a flat bar, and on the other hand at their free end by a tab extending over the entire length of the corresponding contact bar and folded to be disposed on the side of the external face of said corresponding contact strip, said improvements being characterized in that the free ends contact strips each have a lug, while the tabs each have a slot arranged so as to receive the corresponding lug.

Grâce à cette disposition, les barrettes de contacts ne portent pas contre les languettes, puisque les ergots viennent s'insérer dans les lumières.Thanks to this arrangement, the contact strips do not bear against the tabs, since the pins are inserted into the slots.

De préférence, chaque ergot est terminé par une extrémité biseautée et sa longueur est telle qu'il ne peut faire saillie à la surface latérale externe de la languette correspondante.Preferably, each lug is terminated by a beveled end and its length is such that it cannot protrude from the external lateral surface of the corresponding tongue.

Afin que les ergots soient protégés pour éviter que les barrettes de contacts soient endommagées lors de la mise en place de l'organe mâle, les extrémités libres des barrettes sont terminées par des rabats pliés pour s'étendre entre les barrettes de contacts pour masquer les ergots.So that the pins are protected to prevent the contact strips from being damaged during the positioning of the male member, the free ends of the strips are terminated by folded flaps to extend between the contact strips to hide the lugs.

Afin de renforcer la rigidité de l'organe de contact, les languettes comportent chacune, au voisinage de leur extrémité opposée, à leur extrémité libre un embouti portant contre un embouti correspondant des ailes.In order to reinforce the rigidity of the contact member, the tongues each comprise, near their opposite end, at their free end a stamped bearing against a corresponding stamped wings.

Pour améliorer le contact avec l'organe mâle, chaque barrette de contact, au voisinage de son extrémité libre et du côté de sa face tournée en regard de l'autre, est pourvue d'un bossage.To improve contact with the male member, each contact strip, in the vicinity of its free end and on the side of its face turned opposite the other, is provided with a boss.

Afin de faciliter la mise en place de l'organe, selon l'invention, dans un canal d'un élément de boîtier, les extrémités libres des languettes sont légèrement plus rapprochées l'une de l'autre que les extrémités opposées auxdites extrémités libres.In order to facilitate the positioning of the member, according to the invention, in a channel of a housing element, the free ends of the tongues are slightly closer to each other than the ends opposite to said free ends. .

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexés, dans lesquels :The invention will now be described in more detail with reference to a particular embodiment given by way of example only and shown in the accompanying drawings, in which:

Figure 1 est une vue en plan d'un flan découpé pour former l'organe de contact, selon l'invention.Figure 1 is a plan view of a blank cut to form the contact member according to the invention.

Figure 2 est une vue en perspective montrant l'organe de contact en cours de pliage.Figure 2 is a perspective view showing the contact member during folding.

Figure 3 est une vue en perspective de l'organe de contact terminé.Figure 3 is a perspective view of the finished contact member.

Figure 4 est une vue en plan partiellement en coupe montrant l'organe de contact pourvu d'un organe mâle correspondant.Figure 4 is a plan view partially in section showing the contact member provided with a corresponding male member.

L'organe de contact représenté aux figures est réalisé dans une bande de métal bonne conductrice de l'électricité et douée d'une certaine élasticité.The contact member shown in the figures is made of a metal strip that is good conductor of electricity and has a certain elasticity.

La bande est découpée pour présenter un corps 1 avec à une extrémité deux pattes 2 destinées à être serties sur un conducteur et au voisinage de ces deux pattes, deux autres pattes 4 destinées à être serties sur une extrémité dénudée dudit conducteur. On a représenté ici des pattes de sertissage disposée dans l'axe de l'organe de contact, mais bien entendu celles-ci peuvent être disposées différemment, par exemple, en drapeau.The strip is cut to present a body 1 with at one end two tabs 2 intended to be crimped onto a conductor and in the vicinity of these two tabs, two other tabs 4 intended to be crimped onto a stripped end of said conductor. Crimping lugs are shown here arranged in the axis of the contact member, but of course these can be arranged differently, for example, in a flag.

Du côté opposé aux pattes 2 le corps 1 est découpé pour présenter deux barrettes 6 et 7 et deux languettes 5 et 8 s'étendant parallèlement entre elles et sensiblement parallèlement à l'axe longitudinal du corps 1.On the side opposite the legs 2, the body 1 is cut to present two bars 6 and 7 and two tongues 5 and 8 extending parallel to each other and substantially parallel to the longitudinal axis of the body 1.

Entre les barrettes 6 et 7 est ménagée une large ouverture 9 dans le fond de laquelle est découpée une plaquette 10 destinée à constituer une butée.Between the bars 6 and 7 is formed a wide opening 9 in the bottom of which is cut a plate 10 intended to constitute a stop.

La languette 5 comporte, à son extrémité libre, deux encoches 11 et est séparée de la barrette 6 par une fente 12 dont le fond forme une plus large entaille 13.The tongue 5 has, at its free end, two notches 11 and is separated from the bar 6 by a slot 12, the bottom of which forms a wider notch 13.

La languette 5, au voisinage de son extrémité libre, est pourvue d'une ouverture 14.The tongue 5, in the vicinity of its free end, is provided with an opening 14.

La languette 8 est séparée de la barrette 7 par une fente 17 dont le fond forme une large entaille 18.The tongue 8 is separated from the bar 7 by a slot 17, the bottom of which forms a wide notch 18.

La languette 8 est percée d'une ouverture 19 au voisinage de son extrémité libre qui comporte deux encoches 20.The tongue 8 is pierced with an opening 19 in the vicinity of its free end which has two notches 20.

Le bord libre de la languette 5 est destiné à être plié pour former un rebord 5a, tandis que la partie de l'extrémité libre située entre les deux encoches 11 est pliée pour former un rabat 5b et le bord adjacent à la fente 12 est plié pour constituer un rebord 5c.The free edge of the tongue 5 is intended to be folded to form a flange 5 a , while the part of the free end situated between the two notches 11 is folded to form a flap 5 b and the edge adjacent to the slot 12 is folded to form a ledge 5 c .

La barrette 6 est destinée à former l'une des barrettes de contacts et a une longueur et une largeur correspondant à l'espace délimité par les rebords 5a et 5c et le rabat 5b.The strip 6 is intended to form one of the contact strips and has a length and a width corresponding to the space delimited by the flanges 5 a and 5 c and the flap 5 b .

La languette 8 est identique à la languette 5 et comporte des rebords 8a et 8c et un rabat 8b. Les rabats 5b et 8b constituent une protection pour les barrettes 6 et 7, les extrémités tournées en regard l'une de l'autre étant biseautées.The tongue 8 is identical to the tongue 5 and has flanges 8 a and 8 c and a flap 8 b . The flaps 5 b and 8 b constitute a protection for the bars 6 and 7, the ends turned opposite one another being bevelled.

La barrette 7 a les mêmes dimensions que la barrette 6 et constitue une barrette de contact.The strip 7 has the same dimensions as the strip 6 and constitutes a contact strip.

Les extrémités libres des barrettes de contacts comportent, respectivement, des encoches 21 et 22 qui délimitent des ergots, respectivement, 6a et 7a et dans les languettes 5 et 8 sont pratiquées des lumières 24 et 25 présentant des dimensions suffisantes pour être traversées par des ergots 6a et 7a.The free ends of the contact strips respectively comprise notches 21 and 22 which define lugs, respectively 6a and 7a and in the tabs 5 and 8 are formed of slots 24 and 25 having dimensions sufficient to be traversed by pins 6 a and 7 a .

Les barrettes 6 et 7, sur les faces destinées à être tournées l'une en regard de l'autre, comportent un bossage 26.The bars 6 and 7, on the faces intended to be turned opposite one another, have a boss 26.

Le corps 1 est plié en U pour présenter une âme 1a et deux ailes 1b et 1c, tandis que la plaquette 10 est pliée à 90° de manière à s'étendre dans l'âme du U sensiblement perpendiculairement à celle-ci, les deux barrettes de contacts 6 et 7 venant se situer l'une en regard de l'autre en prolongeant les ailes 1b et 1c et les faces en regard desdites barrettes étant convexes de manière que les ergots 6a et 7a s'étendent dans des directions divergentes, les bossages 26 se faisant vis à vis.The body 1 is folded into a U to present a core 1 a and two wings 1 b and 1 c , while the plate 10 is folded at 90 ° so as to extend into the core of the U substantially perpendicular thereto. , the two contact strips 6 and 7 coming to be located opposite one another by extending the wings 1 b and 1 c and the opposite faces said bars being convex so that the lugs 6a and 7a extend in diverging directions, the bosses 26 being overlooked.

L'extrémité de la languette 5 adjacente à la patte 4 comporte un embouti 27 destiné à porter contre un embouti correspondant 28 de l'aile 1b, des emboutis correspondants étant pratiqués sur la languette 8 et l'aile 1c.The end of the tongue 5 adjacent to the tab 4 has a stamped 27 intended to bear against a corresponding stamped 28 of the wing 1b , corresponding stampings being formed on the tongue 8 and the wing 1c .

La languette 5 est pliée le long d'une ligne prolongeant la fente 12 de manière à s'étendre du côté de la face extérieure de la barrette de contact 6.The tongue 5 is folded along a line extending the slot 12 so as to extend on the side of the external face of the contact strip 6.

La languette 8 est pliée de la même manière que la languette 5 afin de s'étendre du côté de la face externe de la barrette de contact 7.The tongue 8 is folded in the same way as the tongue 5 so as to extend on the side of the external face of the contact strip 7.

Les ergots 6a et 7a sont biseautés à leur extrémité libre et leur longueur est telle que lorsqu'ils sont engagés dans les lumières correspondantes 24 et 25, ils ne font pas saillis à la surface latérale externe des languettes correspondantes 5 et 8.The pins 6 a and 7 a are bevelled at their free end and their length is such that when they are engaged in the corresponding slots 24 and 25, they do not protrude from the external lateral surface of the corresponding tabs 5 and 8.

On réalise ainsi un organe de contact femelle qui offre une grande sécurité d'utilisation. En effet, lorsque cet organe est introduit dans un boîtier, les barrettes de contacts 6 et 7 sont protégées et ne risquent pas d'être déformées. Les rabats 5b et 8b protègent les ergots 6a et 7a contre une mauvaise introduction de l'organe mâle et délimitent la section maximale, à partir de laquelle la mise en place d'un organe mâle n'est pas possible (voir figure 4).A female contact member is thus produced which offers great safety in use. In fact, when this member is inserted into a housing, the contact strips 6 and 7 are protected and do not risk being deformed. The flaps 5 b and 8 b protect the pins 6 a and 7 a against improper introduction of the male organ and delimit the maximum section, from which the establishment of a male organ is not possible (see figure 4).

Les emboutis 27, 28, 29 et 30 augmentent la rigidité de l'ensemble de l'organe de contact.The stampings 27, 28, 29 and 30 increase the rigidity of the entire contact member.

Afin de faciliter la mise en place de l'organe, selon l'invention, dans le canal d'un élément de boîtier, les extrémités des languettes 5 et 8 adjacentes aux rabats 5b et 8b respectivement sont légèrement plus rapprochées l'une de l'autre que les extrémités adjacentes aux emboutis 27 et 30.In order to facilitate the positioning of the member, according to the invention, in the channel of a housing element, the ends of the tongues 5 and 8 adjacent to the flaps 5 b and 8 b respectively are slightly closer together. on the other that the ends adjacent to the stampings 27 and 30.

Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et représenté. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention.Of course, the invention is not limited to the embodiment which has just been described and shown. Many detailed modifications can be made without departing from the scope of the invention.
