Description

L'invention vise la réalisation d'organes de contacts électriques mâles du type comprenant un corps sensiblement à section en U dont une extrémité est prolongée pour constituer un barreau destiné à s'insérer dans un organe de contact électrique femelle, tandis que l'autre extrémité comporte des moyens pour permettre de le raccorder à un conducteur électrique, ces moyens étant, généralement, soit simplement des pattes de sertissage, soit, un organe connu sous la dénomination "raccordement à déplacement d'isolant".The invention relates to the production of male electrical contact members of the type comprising a body substantially of U-shaped section, one end of which is extended to form a bar intended to be inserted into a female electrical contact member, while the other end comprises means for enabling it to be connected to an electrical conductor, these means generally being either simply crimping lugs or a member known under the name "insulation displacement connection".

Pour des raisons de prix de revient et également d'outillages, les organes de contacts de ce type sont réalisés dans des flans métalliques minces d'une matière bonne conductrice de l'électricité convenablement découpés et pliés En effet, il faut, d'une part, que la bande soit découpée et, d'autre part, que les différentes parties constituant l'organe soient pliées et qu'après montage du conducteur certaines parties soient serties.For reasons of cost price and also of tools, the contact members of this type are produced in thin metal blanks of a good electrically conductive material suitably cut and folded. firstly, that the strip is cut and, secondly, that the various parts constituting the member are folded and that after mounting of the conductor certain parts are crimped.

Le barreau qui constitue l'élément de liaison électrique avec l'organe correspondant femelle doit, lui, par contre présenter une certaine résistance mécanique et avoir une épaisseur plus importante que le reste du corps. En général, on forme le barreau en découpant dans la bande une partie d'une largeur supérieure à celle du barreau à obtenir et on réalise une partie soit à section en U, soit à section en L dont les épaisseurs sont rabattues et appliquées l'une contre l'autre.The bar which constitutes the electrical connection element with the corresponding female member must, on the other hand, have a certain mechanical resistance and have a greater thickness than the rest of the body. In general, the bar is formed by cutting from the strip a part of a width greater than that of the bar to be obtained and a part is made either with a U section or with an L section, the thicknesses of which are folded down and applied one against the other.

Une telle manière de procéder présente de nombreux inconvénients.Such a procedure has many drawbacks.

Compte tenu des tolérances, le barreau n'a pas toujours la même épaisseur. Il peut également présenter des différences de formes, les épaisseurs peuvent être plus ou moins bien appliquées l'une contre l'autre ce qui nuit à la bonne qualité de la liaison électrique. De plus, la partie du corps en U adjacente au barreau est obligatoirement plus mince ce qui forme une zone de moindre résistance.Given the tolerances, the bar does not always have the same thickness. It can also have differences in shape, the thicknesses can be more or less applied one against the other, which affects the good quality of the electrical connection. In addition, the part of the U-shaped body adjacent to the bar is necessarily thinner which forms an area of least resistance.

Le brevet français FR-A-1 108 263 décrit une fiche de connexion comprenant, à une extrémité, un élément tubulaire destiné à recevoir un organe mâle et, à l'autre extrémité, des pattes destinées à être serties sur un conducteur électrique.French patent FR-A-1 108 263 describes a connection plug comprising, at one end, a tubular element intended to receive a male member and, at the other end, lugs intended to be crimped on an electrical conductor.

Compte tenu de ce que l'élément tubulaire doit présenter une certaine élasticité et, qu'au contraire les pattes doivent serrer le conducteur, dans ce brevet on propose de réaliser la fiche de connexion à partir d'une bande de métal présentant deux épaisseurs, soit une partie mince destinée à former l'élément tubulaire, et une partie plus épaisse dans laquelle sont réalisés le corps et les pattes.Given that the tubular element must have a certain elasticity and, on the contrary, the tabs must clamp the conductor, in this patent it is proposed to make the connection plug from a metal strip having two thicknesses, or a thin part intended to form the tubular element, and a thicker part in which the body and the legs are made.

L'un des buts de la présente invention est de réaliser, à partir d'un flan métallique présentant deux épaisseurs, un organe mâle de contacts électriques remédiant aux divers inconvénients ci-dessus.One of the aims of the present invention is to produce, from a metal blank having two thicknesses, a male member of electrical contacts remedying the various drawbacks above.

L'organe mâle de contacts électriques, selon l'invention est du type comprenant un corps à section sensiblement en U avec deux ailes et une âme et dont une extrémité est prolongée par un barreau, tandis que l'autre extrémité comporte des moyens pour son raccordement à un conducteur électrique, ledit organe étant réalisé par découpage et pliage à partir d'un flan métallique bon conducteur de l'électricité présentant deux bandes ayant des épaisseurs différentes, et est caractérisé en ce que le barreau et la partie du corps en U, adjacente au barreau ont une épaisseur supérieure à celle du reste des éléments.The male member of electrical contacts, according to the invention is of the type comprising a body of substantially U-shaped section with two wings and a core and one end of which is extended by a bar, while the other end comprises means for its connection to an electrical conductor, said member being produced by cutting and folding from a metal blank which is a good conductor of electricity having two strips having different thicknesses, and is characterized in that the bar and the U-shaped part of the body , adjacent to the bar have a thickness greater than that of the rest of the elements.

Grâce à cette disposition, le barreau a directement la section convenable et on est assuré que la partie adjacente au barreau du corps n'est pas affaiblie.Thanks to this arrangement, the bar has the appropriate section directly and it is ensured that the part adjacent to the bar of the body is not weakened.

Suivant une caractéristique particulière, le barreau s'étend dans le prolongement de l'extrémité libre de l'une des ailes et est plié, d'une part, pour être rapproché de l'autre aile et, d'autre part, pour s'étendre dans un plan médian passant par l'âme du corps.According to a particular characteristic, the bar extends in the extension of the free end of one of the wings and is folded, on the one hand, to be brought together on the other wing and, on the other hand, to extend in a median plane passing through the soul of the body.

Suivant une variante de l'invention, le corps comporte une fente s'étendant transversalement au barreau, le barreau dans sa partie adjacente à la fente étant plié contre le fond de l'âme.According to a variant of the invention, the body comprises a slot extending transversely to the bar, the bar in its part adjacent to the slot being folded against the bottom of the core.

Suivant encore une autre caractéristique, les moyens de raccordement à un conducteur électrique sont du type à déplacement d'isolant et constitués par des pattes découpées dans l'âme et pliée pour s'étendre entre les ailes et dans les bords libres desquels sont pratiquées des fentes.According to yet another characteristic, the means of connection to an electrical conductor are of the insulating displacement type and constituted by tabs cut in the core and folded to extend between the wings and in the free edges of which are made slots.

Suivant une variante de réalisation, les moyens de raccordement à un conducteur électrique sont du type à déplacement d'isolant et constitués de deux branches pliées pour former avec l'âme une partie à section en U et prolongées chacune, à chaque extrémité par une patte, les pattes étant pliées afin que celles de l'une des branches s'étendent en regard de celles correspondantes de l'autre branche.According to an alternative embodiment, the means of connection to an electrical conductor are of the insulating displacement type and consist of two branches folded to form with the core a part with a U-section and each extended at each end by a tab. , the legs being folded so that those of one of the branches extend opposite those corresponding to the other branch.

Suivant un détail constructif, la partie du corps comportant les moyens de raccordement à un conducteur électrique, du type à déplacement d'isolant et adjacente à la partie comportant le barreau est renforcée par une nervure.According to a constructive detail, the part of the body comprising the means of connection to an electrical conductor, of the type with displacement of insulation and adjacent to the part comprising the bar is reinforced by a rib.

De préférence, les branches sont renforcées par des emboutis.Preferably, the branches are reinforced by stampings.

De préférence, l'extrémité du corps opposé à celle comportant le barreau est pourvue de pattes de sertissage pour un conducteur électrique.Preferably, the end of the body opposite to that comprising the bar is provided with crimping lugs for an electrical conductor.

Enfin, la partie du corps pourvue des pattes de sertissage et adjacente à la partie du corps comportant les moyens de raccordement à un conducteur électrique du type à déplacement d'isolant est renforcée par une nervure.Finally, the part of the body provided with crimping lugs and adjacent to the part of the body comprising the means for connection to an electrical conductor of the insulating displacement type is reinforced by a rib.

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

Figure 7 montre à partir d'un flan de métal usiné la réalisation d'encore un autre organe de contact électrique.Figure 7 shows from a machined metal blank the making of yet another electrical contact member.

Figure 8 montre en développé l'organe réalisé suivant la variante de la figure 7.Figure 8 shows in developed form the member produced according to the variant of Figure 7.

Figure 9 et 10 montrent des phases de pliage de l'organe de la figure 8.Figure 9 and 10 show the folding phases of the member of Figure 8.

Figure 11 montre en perspective, l'organe réalisé suivant le développé de la figure 8.FIG. 11 shows in perspective, the member produced according to the structure of FIG. 8.

La figure 1 montre en perspective un flan de métal 1 bon conducteur de l'électricité pour la réalisation d'organes de contacts électriques mâles destinés à coopérer avec des organes de contacts électriques femelles. Le flan est, de préférence revêtu, par exemple étamé.Figure 1 shows in perspective a metal blank 1 good conductor of electricity for the production of male electrical contact members intended to cooperate with female electrical contact members. The blank is preferably coated, for example tinned.

Le flan 1 a une épaisseur relativement importante et est soumis à un usinage de manière à ménager une bande centrale 2 présentant l'épaisseur initiale et deux bandes latérales 3 et 4 ayant une épaisseur plus mince. L'usinage peut être quelconque, par exemple, un fraisage.The blank 1 has a relatively large thickness and is subjected to machining so as to provide a central strip 2 having the initial thickness and two lateral strips 3 and 4 having a thinner thickness. The machining can be any, for example, milling.

Aux figures 3 et 4, on a représenté un organe de contact mâle 7 comprenant trois parties 13, 6 et 8. La partie 13 est terminée, à son extrémité libre, par un barreau 5 destiné à s'insérer dans un organe de contact femelle correspondant. La partie 13 est découpée pour être pliée en U avec une âme 9 et deux ailes 10 et 11, l'âme 9 étant percée d'un trou 12 pour la fixation dans un canal d'un boîtier isolant, tandis que l'aile 10 est prolongée par le barreau 5. La partie 6 est découpée pour présenter deux branches 15 et 16 avec des pattes latérales 17 et 18 pliées l'une en regard de l'autre afin de former un organe pour le raccordement d'un conducteur souple isolé dit : "à déplacement d'isolant".In Figures 3 and 4, there is shown a male contact member 7 comprising three parts 13, 6 and 8. Part 13 is terminated, at its free end, by a bar 5 intended to be inserted in a female contact member corresponding. The part 13 is cut to be folded into a U with a core 9 and two wings 10 and 11, the core 9 being pierced with a hole 12 for fixing in an channel of an insulating housing, while the wing 10 is extended by the bar 5. The part 6 is cut to present two branches 15 and 16 with lateral tabs 17 and 18 folded opposite one another in order to form a member for the connection of an insulated flexible conductor says: "insulation displacement".

Enfin, la partie 8 présente deux languettes 22 et 23, la languette 22 étant destinée à servir de guide pour le conducteur électrique et la languette 23 à constituer une patte de sertissage pour la fixation dudit conducteur.Finally, the part 8 has two tongues 22 and 23, the tongue 22 being intended to serve as a guide for the electrical conductor and the tongue 23 to constitute a crimping lug for fixing said conductor.

La portion intermédiaire de l'organe de contact mâle comprise entre les parties 13 et 6 est renforcée par une nervure 19. De même, la portion située entre les parties 6 et 8 est renforcée par une nervure 21.The intermediate portion of the male contact member between the parts 13 and 6 is reinforced by a rib 19. Likewise, the portion located between the parts 6 and 8 is reinforced by a rib 21.

Enfin, les branches 15 et 16 comportent des emboutis 25 pour éviter l'écartement des branches et rigidifient celles-ci lors de la mise en place du conducteur.Finally, the branches 15 and 16 have stamped 25 to avoid the separation of the branches and stiffen them during the establishment of the conductor.

Comme on le voit sur les figures 2, 3 et 4, le barreau 5 est décalé axialement puis, lors de la mise en forme de l'organe, plié en direction de l'aile 11, et enfin plié pour s'étendre axialement. Cette disposition, permet un gain de matière appréciable lors du découpage desdits organes dans le flan 1 (voir fig. 2).As can be seen in FIGS. 2, 3 and 4, the bar 5 is axially offset then, during the shaping of the member, folded in the direction of the wing 11, and finally folded to extend axially. This arrangement allows an appreciable gain in material when cutting said members from the blank 1 (see fig. 2).

On remarquera que le barreau 5 et une portion 13a de la partie 13 ont une section qui correspond à l'épaisseur de la bande centrale 2, tandis que le reste de l'organe a une épaisseur correspondant à l'épaisseur des bandes latérales 3 et 4.It will be noted that the bar 5 and a portion 13a of the part 13 have a section which corresponds to the thickness of the central strip 2, while the rest of the member has a thickness corresponding to the thickness of the lateral strips 3 and 4.

Comme le flan est étamé lors du découpage du corps les deux faces latérales du barreau 5 ne sont plus revêtues. On remarquera que les faces non étamées, lorsque l'organe de connexion est terminé correspondent aux faces supérieure et inférieure, tandis que les deux autres faces qui sont les faces devant coopérer avec un organe femelle correspondant sont toujours revêtues. Ainsi on est assuré d'un bon contact électrique.As the blank is tinned during cutting of the body, the two lateral faces of the bar 5 are no longer coated. It will be noted that the non-tinned faces, when the connection member is finished correspond to the upper and lower faces, while the other two faces which are the faces which must cooperate with a corresponding female member are always coated. This ensures good electrical contact.

La figure 5 montre une variante d'un organe de contact électrique mâle. Cet organe présente un barreau 25 qui est réalisé dans la bande 2 et qui constitue un prolongement de l'âme 26 d'un corps 34 percé d'un trou 33 et présentant deux ailes 27 et 28 et des pattes de sertissage 29, 30, 31 et 32, le corps 34 étant découpé dans l'une des bandes latérales 3 ou 4. La partie de l'âme 26 et des ailes 27 et 28 adjacentes au barreau 25 sont également découpées dans la bande 2.FIG. 5 shows a variant of a male electrical contact member. This member has a bar 25 which is produced in the strip 2 and which constitutes an extension of the core 26 of a body 34 pierced with a hole 33 and having two wings 27 and 28 and crimping lugs 29, 30, 31 and 32, the body 34 being cut from one of the lateral bands 3 or 4. The part of the core 26 and the wings 27 and 28 adjacent to the bar 25 are also cut from the band 2.

La figure 6 montre encore une variante de réalisation dans laquelle l'organe de contact électrique mâle comporte un corps 41 plié en U pour présenter une âme 36 et deux ailes 37 et 38, l'âme 36 étant prolongée d'un côté par un barreau 35, tandis que de l'autre côté elle est prolongée par un organe de raccordement à déplacement d'isolant 39 présentant deux fentes 42 dont la largeur est inférieure au diamètre de l'âme d'un conducteur isolé à brancher afin que l'introduction dans les fentes 42 cisaille l'isolant afin que la liaison électrique soit assurée. Enfin, le corps 41 est terminé par deux pattes de sertissage 40 destinées à enserrer le conducteur pour assurer sa fixation.FIG. 6 also shows an alternative embodiment in which the male electrical contact member comprises a body 41 folded in a U to present a core 36 and two wings 37 and 38, the core 36 being extended on one side by a bar 35, while on the other side it is extended by an insulating displacement connecting member 39 having two slots 42 whose width is less than the diameter of the core of an insulated conductor to be connected so that the introduction in the slots 42 shears the insulation so that the electrical connection is ensured. Finally, the body 41 is terminated by two crimping lugs 40 intended to grip the conductor to secure it.

Comme dans les exemples précédents le barreau 35 et la partie de l'âme 36 et des ailes 37 et 38 adjacentes audit barreau 35 sont découpés dans la bande 2 et le corps dans l'une des bandes 3 ou 4.As in the previous examples, the bar 35 and the part of the core 36 and the wings 37 and 38 adjacent to said bar 35 are cut from the strip 2 and the body from one of the strips 3 or 4.

Les figures 7 à 11 montrent encore une variante de l'invention dans laquelle on réalise l'organe mâle par découpage, deux à deux disposés tête bèche, de deux corps 50 dans un flan la comportant une bande centrale 2a épaisse et deux bandes marginales minces 3a et 4a.Figures 7 to 11 also show a variant of the invention in which the male member is produced by cutting, two by two arranged head to tail, of two bodies 50 in a blank 1a comprising a thick central strip 2a and two thin marginal strips 3a and 4a.

Chaque corps 50 comprend un barreau 51, une partie 52 destinée à être pliée en U pour présenter deux ailes 60 et 61 et une âme 53, les ailes 60 et 61 ainsi que le barreau 51 étant découpés dans la bande 2a, tandis que les prolongements 54 et 55 desdites ailes sont découpés dans la bande marginale 3a ou 4a. L'âme 53 comporte une partie épaisse située entre les ailes 60 et 61 et une partie plus mince située entre les prolongements 54 et 55.Each body 50 comprises a bar 51, a part 52 intended to be folded in a U to present two wings 60 and 61 and a core 53, the wings 60 and 61 as well as the bar 51 being cut in the strip 2a, while the extensions 54 and 55 of said wings are cut in the marginal strip 3a or 4a. The core 53 has a thick part situated between the wings 60 and 61 and a thinner part situated between the extensions 54 and 55.

Dans l'aile 60 est découpée une fente 62 qui s'étend jusqu'au droit du bord du barreau 51 adjacent à l'aile 61.In the wing 60 is cut a slot 62 which extends to the right of the edge of the bar 51 adjacent to the wing 61.

Le barreau 51 est plié le long de son axe afin (voir fig. 9 et fig. 10) de venir se situer sensiblement dans l'axe longitudinal du corps 50 entre les ailes 60 et 61 contre le fond de l'âme 53.The bar 51 is folded along its axis so (see fig. 9 and fig. 10) that it comes to be situated substantially in the longitudinal axis of the body 50 between the wings 60 and 61 against the bottom of the core 53.

Dans l'âme 53 sont découpées deux languettes 56 et 57 qui sont pliées pour s'étendre perpendiculairement à l'âme et découpées pour présenter des fentes 58, les languettes constituant un organe de raccordement à déplacement d'isolant.In the core 53 are cut two tongues 56 and 57 which are folded to extend perpendicular to the core and cut to present slots 58, the tongues constituting a connecting member with displacement of insulation.
