Description

Organe d'extraction de fiche mâle Male plug extractor
La présente invention est relative à un organe d'extraction de fiche mâle comprenant un moyen de prise sur lequel peut agir au moins un doigt d'utilisateur pour appliquer sur la fiche mâle une force destinée à extraire celle-ci d'une position d'enfonce¬ ment dans un évidement de prise de courant femelle jusque dans une position d'extraction hors de cet évidement.The present invention relates to a male plug extraction member comprising a gripping means on which at least one user finger can act to apply to the male plug a force intended to extract the latter from a position of insertion into a socket outlet socket into an extraction position outside this recess.
En vue d'isoler au maximum les endroits de contact électrique entre les fiches mâles et les prises de courant femelles, on prévoit actuellement de renforcer la coopération entre la fiche mâle et la prise femelle et l'ajustement entre ces pièces coopérantes. Il en résulte qu'une force d'extraction assez intense doit être appliquée sur la fiche mâle si l'on veut l'extraire et cela est ressenti par l'utili¬ sateur comme un désagrément. Celui-ci en arrive fréquemment à solliciter la fiche en la secouant dans tous les sens ce qui mécani-* quement n'est pas bon pour les pièces coopérantes. Fréquemment l'utilisateur saisit même le câble électrique et tire sur celui-ci, ce qui est évidemment très mauvais au niveau du raccordement entre le câble et la fiche mâle. On a déjà essayé de résoudre ce problème en conformant de manière spéciale l'enveloppe protectrice isolante du corps de la fiche. On a par exemple prévu de façonner sa partie arrière, c'est-à-dire du côté câble, avec des rainures pour faciliter la prise de la fiche. On a aussi déjà prévu des enveloppes de fiche sur lesquelles un organe d'extraction de la fiche est façonné d'une pièce sur celle-ci, sous la forme d'un oeillet de prise permettant le passage d'un doigt (voir par exemple Encyclopédie des Sciences Industrielles Quillet, Electricité-Electronique, Applications, Paris, 1973, p. 41, fig. VI-3).In order to isolate as much as possible the places of electrical contact between the male plugs and the female sockets, plans are currently being made to strengthen the cooperation between the male plug and the female socket and the adjustment between these cooperating parts. As a result, a fairly intense extraction force must be applied to the male plug if it is to be extracted and this is felt by the user as an inconvenience. The latter frequently comes to solicit the plug by shaking it in all directions, which mechanically is not good for the cooperating parts. Frequently the user even grabs the electric cable and pulls on it, which is obviously very bad at the connection between the cable and the plug. We have already tried to solve this problem by specially shaping the protective insulating casing of the body of the plug. For example, provision has been made to shape its rear part, that is to say on the cable side, with grooves to facilitate taking the plug. Card envelopes have also already been provided on which a card extracting member is formed in one piece on it, in the form of a gripping eyelet allowing the passage of a finger (see for example Encyclopedia of Industrial Sciences Quillet, Electricité-Electronique, Applications, Paris, 1973, p. 41, fig. VI-3).
Ces dispositifs présentent toutefois le désavantage d'augmenter considérablement le coût des fiches mâles. Par ailleurs, cela ne résout pas le problème du très grand nombre de fiches mâles existantes qui ne disposent pas de cette configuration spéciale.However, these devices have the disadvantage significantly increase the cost of male plugs. Furthermore, this does not solve the problem of the very large number of existing male plugs which do not have this special configuration.
La présente invention a pour but de mettre au point un organe d'extraction de fiche mâle qui soit adaptable aux fiches existantes et qui permette, à un coût extrêmement peu élevé, d'extraire les fiches des évidements prévus dans les prises de courant femelles actuelles. Il faut évidemment que cet organe présente toutes les garanties de sécurité du point de vue électrique et qu'il n'altère pas celles présentées par la prise femelle et la fiche mâle.The present invention aims to develop a male plug extraction member which is adaptable to existing plugs and which allows, at an extremely low cost, to extract the plugs from the recesses provided in current female sockets . It is obviously necessary that this body has all the guarantees of safety from the electrical point of view and that it does not alter those presented by the female socket and the male plug.
Pour résoudre ces problèmes, on a prévu, suivant l'invention un organe d'extraction de fiche mâle du type décrit au début, qui comprend des moyens de fixation de l'organe d'extraction sur la fiche mâle, une partie d'application de force qui prend appui sur une face porte-contacts de la fiche mâle lorsque l'organe d'extrac¬ tion est fixé sur elle par les moyens de fixation, au moins cette partie d'application de force de l'organe d'extraction étant en un matériau thermorésistant et électriquement isolant, et des moyens de transmission de la force susdite, appliquée sur le moyen de prise, à la partie d'application de force. L'organe d'extraction suivant l'invention présente la particularité de permettre Papplication d'une force d'extraction sur la face de la fiche qui porte les broches de contact, c'est-à-dire la face du côté prise de courant femelle. Pendant l'extraction, il n'y a par conséquent aucun danger d'appliquer une traction sur le câble ni de tirer le corps de la fiche suivant un angle non approprié en provo¬ quant ainsi un effort mécanique entre les pièces qui coopèrent. La force d'extraction est appliquée depuis la partie la plus enfoncée de la fiche et la sortie de celle-ci est guidée par l'évidement de la prise de courant femelle qui entoure sa partie avant.To solve these problems, there is provided, according to the invention, a male plug extraction member of the type described at the start, which comprises means for fixing the extraction member on the male plug, an application part. of force which is supported on a contact-carrying face of the male plug when the extraction member is fixed on it by the fixing means, at least this part of force application of the extraction member being of a heat-resistant and electrically insulating material, and means for transmitting the aforementioned force, applied to the gripping means, to the force application part. The extraction member according to the invention has the particularity of allowing the application of an extraction force on the face of the plug which carries the contact pins, that is to say the face of the socket outlet side. female. During extraction, there is therefore no danger of applying traction to the cable or of pulling the body of the plug at an inappropriate angle thereby provoking a mechanical force between the parts which cooperate. The extraction force is applied from the most depressed part of the plug and the output thereof is guided by the recess of the female socket which surrounds its front part.
De préférence, la partie d'application de force de l'organe d'extraction . suivant l'invention présente une surface dont le contour externe correspond à la face porte-contacts de la fiche mâle. Elle peut dans certains cas ne recouvrir qu'une partie de cette face et présenter ainsi une surface inférieure à celle-ci et limitée à elle.Preferably, the force application part of the extraction member. according to the invention has a surface whose external contour corresponds to the contact-carrying face of the male plug. In some cases it may cover only part of this face and thus have a surface area smaller than this and limited to it.
Avantageusement, suivant une forme préférée de réalisation de l'invention, la partie d'application de force est façonnée en un matériau mince résistant à la rupture par traction.Advantageously, according to a preferred embodiment of the invention, the force application part is shaped in a thin material resistant to tensile breakage.
Suivant une forme particulière de l'invention, les moyens de fixation sont détachables de la fiche mâle dans la position d'extraction de celle-ci. On peut éventuellement prévoir aussi une fixation non détachable, par exemple par collage ou scellage. Suivant une forme avantageuse de réalisation de l'invention, les moyens de fixation consistent en au moins une ouver¬ ture prévue dans cette partie d'application de force pour le passage des contacts susdits. Avantageusement ils comprennent une ouverture pour chaque contact et, de préférence, ces ouvertures ont une forme permettant un pinçage des broches de contact, afin d'améliorer ainsi la retenue de l'organe d'extraction sur la fiche mâle, en posit on d'extraction.According to a particular form of the invention, the fixing means are detachable from the male plug in the extraction position thereof. It is also possible to provide a non-detachable fixing, for example by gluing or sealing. According to an advantageous embodiment of the invention, the fixing means consist of at least one opening provided in this force application part for the passage of the aforesaid contacts. Advantageously they include an opening for each contact and, preferably, these openings have a shape allowing a pinching of the contact pins, in order to thus improve the retention of the extraction member on the male plug, in posit on extraction.
Suivant une autre forme de réalisation de l'invention, les moyens de transmission de force sont façonnés en un matériau mince, de préférence flexible, et présentant une épaisseur inférieure à un intervalle formé entre la fiche mâle et l'évidement de la prise femelle, dans la position d'enfoncement précitée.According to another embodiment of the invention, the force transmission means are made of a thin material, preferably flexible, and having a thickness less than an interval formed between the male plug and the recess of the female socket, in the aforementioned insertion position.
Suivant une forme préférée de réalisation de l'in¬ vention, le moyen de prise, la partie d'application de force et les moyens de transmission de l'organe d'extraction sont façonnés dans un même matériau. De préférence, ce matériau est un film de matière plastique résistant à la chaleur, électriquement isolant et mécani¬ quement bien résistant à la rupture lorsqu'il est soumis à une traction. Avantageusement, il a la forme d'un ruban aux deux extrémités duquel sont disposés des moyens de fixation adaptables chacun sur au moins un contact de la fiche mâle. On peut envisager aussi que l'organe d'extraction ait la forme d'un bracelet dont une partie forme le moyen de prise et dont une autre partie diamétralement opposée présente lesdits moyens de fixation. D'autres détails et particularités de l'invention ressortiront de la description donnée ci-après, à titre non limitatif et avec référence aux dessins annexés.According to a preferred embodiment of the invention, the gripping means, the force application part and the means for transmitting the extraction member are made from the same material. Preferably, this material is a film of plastic material resistant to heat, electrically insulating and mechanically resistant to breaking when subjected to traction. Advantageously, it has the form of a ribbon at the two ends of which are arranged attachment means, each adaptable to at least one contact of the male plug. It is also conceivable that the extraction member has the shape of a bracelet, part of which forms the gripping means and of which another diametrically opposite part has said fixing means. Other details and features of the invention will emerge from the description given below, without implied limitation and with reference to the attached drawings.

Sur les dessins, les éléments identiques ou analogues sont désignés par les mêmes références.In the drawings, identical or analogous elements are designated by the same references.
Sur les figures 1 à 3, on a représenté une fiche mâle i répondant aux normes américaines. Cette fiche comporte des contacts mâles sous la forme de broches aplaties 2 et une enve¬ loppe protectrice 3 dont font saillie vers l'avant lesdites broches 2 et vers l'arrière un câble électrique 10 dont les conducteurs sont connectés à ces broches 2 à l'intérieur de l'enveloppe 3. Cette fiche mâle est destinée à être enfoncée dans un évidement de prise de courant de femelle 5, dans lequel sont prévus de manière connue des contacts femelles sous la forme de douilles ou alvéoles. Sur la figure 3, la fiche mâle 1 est représentée en position d'enfoncement dans la prise femelle 5 tandis que sur les figures 1 et 2 est elle représentée en position d'extraction en dehors de l'évidement 4*. L'organe d'extraction suivant l'invention, qui est représenté sur ces figures 1 à 3, est formé d'un ruban 6 fabriqué à partir d'un matériau mince, notamment en un film de matière plastique résistant à la chaleur et électriquement isolant. Comme matériau approprié on peut envisager par exemple un film de polyester et en particulier un film ELINEX (marque enregistrée) de la firme ICI, qui est à base de téréphtalate de polyéthylène. Ce type de film présente, outre les propriétés précitées, l'avantage d'une bonne résistance à la traction et d'une certaine flexibilité. Le ruban utilisé présente avantageusement une épaisseur inférieure à l'intervalle 7 subsistant entre la fiche mâle 1 et l'évidement de la prise femelle 5, en position d'enfoncement de la fiche mâle. A chacune de ses extrémités le ruban 6 présente des ouvertures rectangulaires 8 et respectivement 9 pour chaque contact 2. Avantageusement les ouvertures 8 et 9 présentent une surface légèrement plus étroite que la section transversale des contacts 2. Comme représenté sur la figure 1, les ouvertures 8 sont d'abord passées sur les contacts 2, puis les ouvertures 9. Par leur étroitesse, leur forme et la flexibilité du ruban 6 utilisé, les ouvertures 8 et 9 exercent alors une action de retenue élastique du ruban sur les contacts 2. Ils servent donc de moyens de fixation du ruban 6 sur la fiche mâle 1, même dans la position d'extraction de celle-ci, ainsi que cela ressort de la figure 2.In Figures 1 to 3, there is shown a male plug i meeting American standards. This plug includes male contacts in the form of flattened pins 2 and a protective envelope 3 which protrudes said pins 2 forward and rearward an electric cable 10 whose conductors are connected to these pins 2 to 1. 'interior of the envelope 3. This plug is intended to be inserted in a socket socket socket 5, in which are provided in known manner female contacts in the form of sockets or cells. In Figure 3, the male plug 1 is shown in the insertion position in the socket 5 while in Figures 1 and 2 is shown in the extraction position outside the recess 4 *. The extraction member according to the invention, which is shown in these Figures 1 to 3, is formed of a tape 6 made from a thin material, in particular a film of material heat-resistant and electrically insulating plastic. As suitable material, it is possible, for example, to consider a polyester film and in particular an ELINEX film (registered trademark) from the firm ICI, which is based on polyethylene terephthalate. This type of film has, in addition to the above properties, the advantage of good tensile strength and a certain flexibility. The ribbon used advantageously has a thickness less than the interval 7 remaining between the male plug 1 and the recess of the female socket 5, in the insertion position of the male plug. At each of its ends, the strip 6 has rectangular openings 8 and 9 respectively for each contact 2. Advantageously, the openings 8 and 9 have a slightly narrower surface than the cross section of the contacts 2. As shown in FIG. 1, the openings 8 are first passed over the contacts 2, then the openings 9. By their narrowness, their shape and the flexibility of the ribbon 6 used, the openings 8 and 9 then exert an elastic retaining action of the ribbon on the contacts 2. They therefore serve as means for fixing the ribbon 6 to the male plug 1, even in the extraction position of the latter, as can be seen from FIG. 2.
L'organe d'extraction, tel que représenté sur la figure 2, comporte alors plusieurs parties. Une première partie 11, appelée partie d'application de force, prend appui sur la face porte- contacts 12 de la fiche mâle 1, lorsque l'organe d'extraction est fixé sur elle. En position d'enfoncement, cette partie d'application de force 11 se trouve donc entre la face porte-contacts 12 susdite et le fond de l'évidement 4 de la prise femelle 5.The extraction member, as shown in Figure 2, then comprises several parts. A first part 11, called the force application part, bears on the contact-carrying face 12 of the plug 1, when the extraction member is fixed to it. In the driving-in position, this force-applying part 11 is therefore located between the above-mentioned contact carrier face 12 and the bottom of the recess 4 of the socket 5.
Une deuxième partie 13 est dans l'exemple illustré située à mi-distance des extrémités du ruban 6. Cette deuxième partie .13 sert de moyen de prise de l'organe d'extraction sur lequel peut agir au moins un doigt (voir figure 3) de l'utilisateur pour ap¬ pliquer une force dans le sens représenté par la flèche F.A second part 13 is in the illustrated example located midway between the ends of the ribbon 6. This second part .13 serves as a means of gripping the extraction member on which at least one finger can act (see FIG. 3 ) of the user to apply a force in the direction represented by the arrow F.
Une troisième partie de l'organe d'extraction est, dans l'exemple illustré, formé par les sections latérales 14 du ruban é qui joignent les extrémités de celui-ci à la partie d'application de force 13. Lorsqu'une force de traction est appliquée dans le sens F sur la partie d'application de force 13, ces sections latérales 14 servent de moyens de transmission qui transmettent cette force à la partie d'application de force 11 en appui sur la face porte-contacts 12 de la fiche mâle. Cette opération permet une extraction aisée de la fiche mâle sans toucher celle-ci, d'une manière guidée correcte¬ ment par la prise femelle 5 et sans traction sur le câble 10.A third part of the extraction member is, in the example illustrated, formed by the lateral sections 14 of the ribbon which join the ends thereof to the application part. force 13. When a tensile force is applied in the direction F on the force application part 13, these lateral sections 14 serve as transmission means which transmit this force to the force application part 11 in support on the contact carrier face 12 of the male plug. This operation allows easy extraction of the male plug without touching the latter, in a manner correctly guided by the female socket 5 and without pulling on the cable 10.
Dans cet exemple de réalisation illustré sur les figures 1 à 3, les moyens de fixation, c'est-à-dire les ouvertures 8 et 9, sont prévus de manière à pouvoir les détacher et à séparer ainsi la fiche mâle de l'organe d'extraction même après utilisation. On peut bien sûr aussi prévoir des moyens de fixation non détachables, par exemple par collage, scellage, ou tout autre moyen connu, quelcon¬ que, sur le corps de l'enveloppe 3 de la fiche 1. Dans ce cas, évidem- ment les ouvertures 8 et 9 peuvent être dimensionnées différemment et ne plus servir eiles-même de moyens de fixation.In this embodiment illustrated in Figures 1 to 3, the fixing means, that is to say the openings 8 and 9, are provided so that they can be detached and thus separate the plug from the member even after use. It is of course also possible to provide non-detachable fixing means, for example by gluing, sealing, or any other known means, whatever, on the body of the envelope 3 of the plug 1. In this case, obviously the openings 8 and 9 can be dimensioned differently and no longer serve eiles itself fixing means.

1 à 3, à la transition entre la partie d'application de force 11 et les sections latérales 14 du ruban 6, on a prévu une incision trans*- versale 15 qui facilite le pliage du ruban 6 au bord de la face porte-. contacts 12.1 to 3, at the transition between the force application part 11 and the lateral sections 14 of the ribbon 6, a trans * - transverse incision 15 is provided which facilitates the folding of the ribbon 6 at the edge of the carrier face. contacts 12.
L'exemple de réalisation représenté sur la figure 4 est un autre organe d'extraction adapté pour une fiche 1 répondant à des normes européennes. Cet organe d'extraction correspond à celui représenté sur les figures 1 à 3 avec cette différence que les extrémités du ruban 6, donc la partie d'application de force 16, présentent une surface dont le contour externe correspond à la face porte-contacts de la fiche 1, alors que, dans l'exemple précédent, cette surface était inférieure à la face porte-contacts.The embodiment shown in Figure 4 is another extraction member adapted for a plug 1 meeting European standards. This extraction member corresponds to that shown in FIGS. 1 to 3 with the difference that the ends of the strip 6, therefore the force application part 16, have a surface whose external contour corresponds to the contact-carrying face of sheet 1, whereas, in the previous example, this surface was less than the contact carrier face.
Par ailleurs, des ouvertures circulaires 17 prolongées vers l'arrière par des incisions longitudinales 18 sont prévues à la transition entre la partie d'application de force 16 et les sections latérales 14 du ruban 6, pour permettre le pliage de celui-ci le long des différentes arêtes que présente la fiche mâle I illustrée.Furthermore, circular openings 17 extended rearwards by longitudinal incisions 18 are provided at the transition between the force application part 16 and the lateral sections 14 of the tape 6, to allow it to be folded along different edges presented by the male plug I illustrated.
Il est évident que la forme et l'emplacement de ces fentes, incisions et ouvertures peuvent varier en fonction de la forme extérieure de l'enveloppe 3 de la fiche mâle 1.It is evident that the form and location of these slots, incisions and openings can vary depending on the external shape of the casing 3 of the plug 1.
Enfin, chaque extrémité du ruban 6 de l'organe d'extraction selon la figure 4 ne présente qu'une ouverture 19 permet- tant le passage des deux broches de contact à la fois.Finally, each end of the ribbon 6 of the extraction member according to FIG. 4 has only one opening 19 allowing the passage of the two contact pins at the same time.
L'organe d'extraction représenté à plat sur la figure 5 a également la forme d'un ruban 6. Il est prévu pour des fiches mâles comportant une broche supplémentaire, par exemple pour la prise de terre. A chaque extrémité le ruban 6 présente donc trois trous circulaires 20 pour le passage des trois broches et le ruban peut alors présenter à ses extrémités, c'est-à-dire dans sa partie d'application de force 27, une largeur plus grande que dans sa partie centrale.The extraction member shown flat in FIG. 5 also has the form of a ribbon 6. It is provided for male plugs comprising an additional pin, for example for the earth connection. At each end the ribbon 6 therefore has three circular holes 20 for the passage of the three pins and the ribbon can then have at its ends, that is to say in its force application part 27, a width greater than in its central part.
L'organe d'extraction représenté sur la figure 6 a la forme d'un bracelet 21. Ici les moyens de fixation sont formés de trois trous 22 dans lesquels peuvent passer les broches d'une fiche avec prise de terre. Cette partie du bracelet 21 forme la partie d'application de force précitée tandis que la partie diamétralement opposée 24 du bracelet forme le moyen de prise de celui-ci, ces deux parties étant reliées par des parties latérales 25 et 26 pour la transmission de la force du moyen de prise à la partie d'application de force.The extraction member shown in FIG. 6 has the form of a bracelet 21. Here the fixing means are formed by three holes 22 through which the pins of a plug with earth connection can pass. This part of the bracelet 21 forms the aforementioned force application part while the diametrically opposite part 24 of the bracelet forms the gripping means of the latter, these two parts being connected by lateral parts 25 and 26 for the transmission of the force of the gripping means at the force applying part.
Il doit être entendu que l'invention n'est en aucune façon limitée aux formes de réalisation décrites ci-dessus et que bien des modifications peuvent y être apportées sans sortir du cadre de l'invention.It should be understood that the invention is in no way limited to the embodiments described above and that many modifications can be made without departing from the scope of the invention.
Il est évident notamment que chaque prise peut demander une forme de réalisation particulière des fiches et que toute modification, même future, dans la forme des fiches mâles peut entraîner une modification de forme de l'organe d'extraction, tout en restant dans le cadre de l'invention.It is obvious in particular that each outlet may require a particular embodiment of the plugs and that any modification, even in the future, in the shape of the male plugs can result in a modification of the shape of the extraction member, while remaining within the framework of the invention.
On peut prévoir d'ailleurs certains organes d'extrac¬ tion présentant une multiplicité d'ouvertures différentes et d'incisions variées pour permettre le passage de broches différentes et l'adaptation sur des fiches de plusieurs types à la fois.It is also possible to provide certain extraction members having a multiplicity of different openings and various incisions to allow the passage of different pins and the adaptation to cards of several types at the same time.
Il n'est pas nécessaire non plus que l'organe d'extrac- tion soit réalisé d'une pièce en un seul et même matériau. Il suffit que la partie d'application de force soit thermiquement résistante et électriquement isolante. Nor is it necessary for the extractor tion is made in one piece from a single material. It suffices that the force application part is thermally resistant and electrically insulating.
