Description

Elément d'assemblage Assembly element
La présente invention a pour objet un élément d'assemblage, plus particulièrement un élément d'assemblage amovible ou réversible, c'est-à-dire pouvant être facilement enlevé pour libérer les pièces qu'il est destiné à fixer.The present invention relates to an assembly element, more particularly a removable or reversible assembly element, that is to say that can be easily removed to release the parts that it is intended to fix.
Cet élément d'assemblage est conçu dans le but de réaliser un gain de temps important dans le montage et le démontage de pièces mécaniques fabriquées en grande série, comme par exemple les fiches électriques.This assembly element is designed in order to save significant time in the assembly and disassembly of mechanical parts produced in large series, such as electrical plugs.
Le dessin annexé illustre trois formes d'exécutions de l'élément d'assemblage selon la présente invention.The accompanying drawing illustrates three forms of execution of the assembly element according to the present invention.
La figure 1 est une vue en perspective d'une première forme d'exécution de l'élément d'assemblage.Figure 1 is a perspective view of a first embodiment of the assembly element.
La figure 2 illustre l'élément d'assemblage de la figure 1 en position de service fixant ensemble deux pièces mécaniques. Les figures 3 et 4 illustrent deux autres formes d'exécutions de l'élément d'assemblage.FIG. 2 illustrates the assembly element of FIG. 1 in the service position fixing together two mechanical parts. Figures 3 and 4 illustrate two other forms of execution of the assembly element.
L'élément d'assemblage illustré à la figure 1 comporte une tête munie d'un organe de guidage 1 et d'un organe de butée 2. Dans l'exemple illustré, l'organe de guidage 1 est formé d'une plaque d'une largeur déterminée, correspondant au diamètre du perçage d'une pièce mécanique dans lequel l'organe d'assemblage doit être introduit. Les faces latérales 3 de cette plaque coopèrent en position de service assemblées avec la première pièce mécanique A à assembler et positionnent sans jeu l'élément d'assemblage dans cette pièce mécanique. L'organe de butée 2 est destiné à prendre appui sur la face supérieure de la première pièce mécanique A à assembler. Dans cette forme d'exécution cet organe de butée, fixé par sa partie médiane ou venu d'une pièce de fabrication avec la plaque, comporte des extensions latérales destinées à prendre appui sur la surface supérieure de la première pièce mécanique A à assembler. Ces extensions latérales présentent une certaine élasticité. L'élément d'assemblage comporte encore deux lames flexibles 4 solidaires de la plaque et munies à leurs extrémités d'un bec d'accrochage 5 dirigé vers l'extérieur. La face inférieure de ces becs 5 est oblique de sorte que les surfaces latérales 6 de ces becs 5 se situent sur une surface conique allant en s'évasant en direction de l'organe de butée 2.The assembly element illustrated in FIG. 1 comprises a head provided with a guide member 1 and with a stop member 2. In the example illustrated, the guide member 1 is formed by a plate d 'a determined width, corresponding to the diameter of the bore of a mechanical part into which the assembly member must be introduced. The lateral faces 3 of this plate cooperate in the service position assembled with the first mechanical part A to be assembled and position the assembly element without play in this mechanical part. The stop member 2 is intended to bear on the upper face of the first mechanical part A to be assembled. In this embodiment, this stop member, fixed by its middle part or coming from a manufacturing part with the plate, has lateral extensions intended to bear on the upper surface of the first mechanical part A to be assembled. These lateral extensions have a certain elasticity. The assembly element also comprises two flexible blades 4 secured to the plate and provided at their ends with a hooking spout 5 directed towards the outside. The underside of these spouts 5 is oblique so that the lateral surfaces 6 of these spouts 5 are located on a conical surface which widens in the direction of the stop member 2.
La figure 2 illustre l'assemblage de deux pièces mécaniques A, B. Ces deux pièces sont traversées par des perçages 7,8 coaxiaux et de même diamètre correspondant à la largeur de la plaque de l'élément d'assemblage. Dans l'exemple illustré, la pièce B à assembler comporte sur sa face libre un évidement formant un épaulement 9 entourant le perçage 8.Figure 2 illustrates the assembly of two mechanical parts A, B. These two parts are crossed by holes 7.8 coaxial and of the same diameter corresponding to the width of the plate of the connecting element. In the example illustrated, the part B to be assembled has on its free face a recess forming a shoulder 9 surrounding the bore 8.
Les pièces mécaniques A, B étant superposées de manière à ce que leurs perçages 7,8 coïncident, l'élément d'assemblage est introduit dans ceux-ci, les becs d'accrochage 5 se rapprochant par déformation élastique des lames 4. L'organe de butée 2 entre en contact avec la face supérieure de la pièce A et est déformé elastiquement par une pression qui permet aux becs d'accrochage 5 de venir se loger contre l'épaulement formé par l'évidement 5 par la force élastique de rappel des lames 4. Les deux pièces mécaniques A, B sont ainsi assemblées et pressées l'une contre l'autre par l'action élastique de l'organe de butée 2.The mechanical parts A, B being superimposed so that their holes 7,8 coincide, the assembly element is introduced into them, the hooking nozzles 5 approaching by elastic deformation of the blades 4. The abutment member 2 comes into contact with the upper face of the part A and is elastically deformed by a pressure which allows the hooking nozzles 5 to come to lodge against the shoulder formed by the recess 5 by the elastic return force blades 4. The two mechanical parts A, B are thus assembled and pressed against each other by the elastic action of the stop member 2.
Il est évident que la longueur des lames 4 de l'élément d'assemblage est définie en fonction de l'épaisseur des pièces à assembler.It is obvious that the length of the blades 4 of the assembly element is defined as a function of the thickness of the parts to be assembled.
Cet assemblage est réversible car il suffit de rapprocher les becs 5 l'un de l'autre, par exemple à l'aide d'un outil présentant un cône femelle à son extrémité pour que ces becs échappent à l'épaulement de la pièce B et que l'élément d'assemblage puisse être retiré et séparé des pièces A, B. Cet élément d'assemblage permet un montage et un démontage rapides.This assembly is reversible because it suffices to bring the spouts 5 close to each other, for example using a tool having a female cone at its end so that these spouts escape the shoulder of the part B and that the assembly element can be removed and separated from the parts A, B. This assembly element allows rapid assembly and disassembly.
Une fois mis en place il ne peut pas se libérer sous l'action de vibrations contrairement à des assemblages vissés.Once in place, it cannot be released under the action of vibrations, unlike screwed assemblies.
La préparation des pièces à assembler est simple, pas de taraudage, seuls des perçages simples sont à effectuer. Enfin ces éléments d'assemblage sont bon marché car ils peuvent être obtenus par étampage s'ils sont métalliques ou injection s'ils sont en un matériau plastique.The preparation of the parts to be assembled is simple, no tapping, only simple drilling is required. Finally, these assembly elements are inexpensive because they can be obtained by stamping if they are metallic or injection if they are made of a plastic material.
Dans la seconde forme d'exécution illustrée à la figure 3, l'élément d'assemblage est formé d'une tige pleine 10 cylindrique munie d'une collerette 1 1 formant l'organe de butée à l'une de ses extrémités. L'autre extrémité de la tige 10 comporte une creusure cylindrique borgne 12 et quatre fraisures 13 délimitant ainsi des pattes élastiques 14. Chacune de ces pattes 14 se termine par un bec 15 dirigé radialement vers l'extérieur et dont la surface latérale 16 est conique allant en s'évasant en direction de la collerette 11.In the second embodiment illustrated in Figure 3, the connecting element is formed of a solid cylindrical rod 10 provided with a collar 1 1 forming the stop member at one of its ends. The other end of the rod 10 comprises a blind cylindrical recess 12 and four countersinks 13 thus delimiting elastic tabs 14. Each of these tabs 14 ends in a spout 15 directed radially outwards and whose lateral surface 16 is conical flaring towards the flange 11.
La partie pleine de la tige 10 forme l'organe de guidage qui coopère avec les perçages 7,8 des pièces A, B à assembler.The solid part of the rod 10 forms the guide member which cooperates with the holes 7,8 of the parts A, B to be assembled.
Ici également la mise en place de l'élément d'assemblage est aisé et rapide, il est introduit dans les perçages 7,8 des pièces A, B et une simple pression permet aux becs de prendre place sur l'épaulement 9 ou sur la face libre de la pièce B. Pour démonter l'assemblage il suffit de rapprocher les becs 15 les uns des autres pour les libérer de la surface libre de la pièce B.Here also the installation of the assembly element is easy and quick, it is introduced into the holes 7.8 of the parts A, B and a simple pressure allows the nozzles to take place on the shoulder 9 or on the free face of part B. To dismantle the assembly, it suffices to bring the spouts 15 together to free them from the free surface of part B.
Dans la troisième forme d'exécution de l'élément d'assemblage illustrée à la figure 4, la tige 10 est tubulaire, ce qui réduit la masse de matière utilisée. Ces éléments d'assemblage sont bon marché, facile à utiliser et permettent un maintien durable des pièces assemblées. In the third embodiment of the assembly element illustrated in FIG. 4, the rod 10 is tubular, which reduces the mass of material used. These assembly elements are inexpensive, easy to use and allow a durable maintenance of the assembled parts.
