La fermeture de l'enceinte 1 1 par le couvercle se fait en fixant l'enceinte au couvercle au moyen d'un moyen de fixation 1 1 1 solidaire de l'enceinte et destiné à traverser un trou pratiqué dans le couvercle du boîtier 1 . Le moyen de fixation 1 1 1 assure la fixation de l'enceinte au couvercle au moyen d'une extrémité du moyen de fixation apte à être déformée par bouterollage et dépassant du trou pratiqué dans le couvercle du boîtier 1 .  [0003] Figure 1 illustrates an existing waterproof housing 1. The sealed housing 1 comprises fixing lugs 14 for fixing the housing 1 to one (or more) other element (s), for example a wall on which the housing is fixed. It comprises an enclosure 1 1 in which are arranged the elements to be contained by the housing and protected from moisture and / or dust, for example an electronic card. The enclosure 1 1 is intended to be closed by a cover (not visible in Figure 1). Closing the enclosure 1 1 by the cover is done by fixing the enclosure to the cover by means of a fastening means 1 1 1 secured to the enclosure and intended to pass through a hole in the housing cover 1. The fastening means 1 1 1 ensures the attachment of the enclosure to the cover by means of one end of the fixing means adapted to be deformed by snap-fitting and protruding from the hole made in the cover of the housing 1.
[ 0004 ] Un moyen d'étanchéité 13, par exemple un joint, est disposé le long de l'enceinte 1 1 du boîtier 1 et forme une zone fermée et étanche 1 1 3 (une fois l'enceinte fermée par le couvercle) dans l'enceinte du boîtier 1 . A l'intérieur de la zone 1 13 les éléments, du type carte électronique, qui ne doivent pas être exposés à la poussière et/ou à l'humidité sont disposés. Une fois le couvercle fixé à l'enceinte 1 3, et le boîtier fermé, il est nécessaire de maintenir l'étanchéité au sein de la zone 1 13. [ 0005] Un inconvénient majeur de ce type de boîtier est son encombrement, encombrement qui doit constamment être minimisé dans le domaine automobile. Ici, les moyens de fixation 1 1 1 sont disposés sur les pattes de fixation 14, et un emplacement doit leur être réservé sur ces pattes 14. La présence d'un moyen de fixation 1 1 1 sur une patte de fixation 14 génère un encombrement supérieur à l'encombrement qui serait causé par : A sealing means 13, for example a seal, is disposed along the enclosure 1 1 of the housing 1 and forms a closed and sealed area 1 1 3 (once the enclosure closed by the cover) in the case enclosure 1. Inside the zone 1 13 elements, electronic card type, which must not be exposed to dust and / or moisture are arranged. Once the lid is fixed to the enclosure 1 3, and the housing closed, it is necessary to maintain the seal within the zone 1 13. A major disadvantage of this type of housing is its size, size which must constantly be minimized in the automotive field. Here, the fastening means 1 1 1 are arranged on the fastening lugs 14, and a location must be reserved for them on these lugs 14. The presence of a fastening means 1 1 1 on a fastening lug 14 generates a bulk greater than the clutter that would be caused by:
les dimensions intrinsèques du boîtier, à savoir les dimensions de l'enceinte et du couvercle ;  the intrinsic dimensions of the housing, namely the dimensions of the enclosure and the cover;
auxquelles s'ajoutent les d imensions des pattes de fixation 14 du boîtier 1 à d'autres éléments.  to which are added the dimensions of the fixing lugs 14 of the housing 1 to other elements.
[ 0006] Dans le cas de l'util isation du boîtier dans un habitacle de véhicule, le gain de place est constamment recherché et la présence des moyens de fixation 1 1 1 sur les pattes de fixation 1 4 engendre une perte de place coûteuse dans l'habitacle d'un véhicule. Il n'est cependant pas possible de déplacer les moyens de fixation 1 1 1 en dehors des pattes de fixation 14 et de les placer au niveau du joint 13 ou de la zone étanche 1 13 car cela créerait un problème d'étanchéité du boîtier. En effet, un tel moyen de fixation 1 1 1 traverse un trou pratiqué dans le couvercle du boîtier, et il peut y avoir des problèmes d'étanchéité au niveau du trou. Ce problème d'étanchéité est visible, plus particulièrement en référence aux figures 2A et 2B.  In the case of the use of the housing in a vehicle cabin, the space saving is constantly sought and the presence of the fastening means 1 1 1 on the brackets 1 4 generates a costly loss of place in the interior of a vehicle. However, it is not possible to move the fastening means 1 1 1 outside the fastening lugs 14 and place them at the seal 13 or the sealed zone 1 13 as this would create a sealing problem of the housing. Indeed, such a fastening means 1 1 1 through a hole in the housing cover, and there may be sealing problems at the hole. This sealing problem is visible, more particularly with reference to FIGS. 2A and 2B.
[ 0007 ] Les figures 2A et 2B illustrent un couvercle 12 de boîtier 1 existant, couvercle 12 dans lequel est pratiqué un trou 121 . Un moyen de fixation 1 1 1 , ici un pion de bouterollage, solidaire de l'enceinte (non visible sur ces figures) du boîtier 1 est visible sur les figures 2A et 2B.  Figures 2A and 2B illustrate a cover 12 of existing housing 1, cover 12 in which is formed a hole 121. A fastening means January 1, here a pegging peg, integral with the enclosure (not visible in these figures) of the housing 1 is visible in Figures 2A and 2B.
[ 0008 ] Le moyen de fixation 1 1 1 traverse le trou 121 , et une extrémité 1 12 du moyen de fixation 1 1 1 dépasse du trou 121 . Cette extrémité 1 12 du moyen de fixation 1 1 1 est déformable par bouterollage. Sur la figure 2A, l'extrémité 1 12 du moyen de fixation, avant bouterollage, est tubulaire. L'enceinte n'est pas fixée au couvercle 12 sur la figure 2A.  The fastening means 1 1 1 passes through the hole 121, and an end 1 12 of the fastening means 1 1 1 protrudes from the hole 121. This end 1 12 of the fastening means January 1 is deformable by bouterollage. In Figure 2A, the end 1 12 of the fastening means, before pegging, is tubular. The enclosure is not attached to the cover 12 in Figure 2A.
[ 0009] Après bouterollage, sur la figure 2B, l'extrémité 1 12 du moyen de fixation est déformée (ici de forme arrondie) et assure la fixation de l'enceinte, dont l e moyen de fixation 1 1 1 est solidaire, au couvercl e 1 2. En effet, l a déformation due au bouterollage de l'extrémité 1 12 du moyen de fixation crée une liaison mécanique entre le moyen de fixation 1 1 1 et le couvercle 12. Cependant, au niveau des zones de contact 2 entre le couvercle et le moyen de fixation 1 1 1 , l'étanchéité de l'intérieur du boîtier n'est pas garantie. Un tel moyen de fixation 1 1 1 ne peut donc pas être déplacé d'une patte de fixation du couvercle à la zone étanche, sans remettre en cause l'étanchéité de la zone étanche. After pegging, in Figure 2B, the end 1 12 of the fastening means is deformed (here of rounded shape) and ensures the attachment of the enclosure, the fastening means 1 1 1 is secured to the lid e 1 2. Indeed, the deformation due to the pegging of the end 1 12 of the fastening means creates a mechanical connection between the fastener 1 1 1 and the cover 12. However, at the contact areas 2 between the cover and the fastening means 1 1 1, the sealing of the interior of the housing is not guaranteed . Such a fixing means 1 1 1 can not be moved from a fastening tab of the cover to the sealed zone, without questioning the tightness of the sealed zone.
EXPOSE DE L'INVENTION SUMMARY OF THE INVENTION
[0010] L'invention vise à remédier à tout ou partie des inconvénients de l'état de la technique identifiés ci-dessus, et notamment à proposer des moyens de fixation du couvercle d'un boîtier étanche à l'enceinte d'un boîtier étanche de façon à garantir l'étanchéité tout en rendant possible la réduction d'encombrement du boîtier.  The invention aims to remedy all or part of the disadvantages of the state of the art identified above, and in particular to provide means for fixing the cover of a sealed housing to the enclosure of a housing tight so as to ensure tightness while making it possible to reduce the size of the housing.
[0011] Dans ce dessein , un aspect de l'invention se rapporte à un boîtier étanche comportant :  In this purpose, one aspect of the invention relates to a sealed housing comprising:
une enceinte ;  a speaker ;
- un couvercle ; un moyen de fixation de l'enceinte au couvercle ;  - a lid ; means for fixing the enclosure to the cover;
ledit couvercle comportant un trou, ledit trou étant adapté pour être traversé par le moyen de fixation ; une extrémité dudit moyen de fixation dépassant du trou pour être déformée par bouterollage ; le couvercle comportant un renfort continu en périphérie du trou et lors du bouterollage de l'extrémité du moyen de fixation, le renfort fondant au moins partiellement en contact avec l'extrémité du moyen de fixation de façon à former une soudure. said cover having a hole, said hole being adapted to be traversed by the fixing means; an end of said fastening means protruding from the hole to be deformed by snapping; the cover comprising a continuous reinforcement at the periphery of the hole and during the pegging of the end of the fastening means, the reinforcement melting at least partially in contact with the end of the fastening means so as to form a weld.
[0012] Lors du bouterollage de l'extrémité du moyen de fixation, afin de déformer cette pièce de façon à créer une liaison mécanique entre le couvercle et le moyen de fixation, l'extrémité du moyen de fixation fond partiellement grâce à la chaleur apportée lors du bouterollage. La chaleur apportée lors du bouterollage ramol l it l 'extrém ité d u moyen de fixation, mais aussi le renfort continu en périphérie du trou d uq uel dépasse l 'extrém ité d u moyen de fixation. Ce ramollissement permet aux matériaux, constituant le renfort et l'extrémité du moyen de fixation, de se mélanger l'un avec l'autre créant ainsi une soudure entre le renfort et l'extrémité du moyen de fixation . Cette soudure, garantie entre les deux éléments, assure l'étanchéité au niveau des zones de contact entre le couvercle (via le renfort) et le moyen de fixation. Un tel moyen de fixation étanche peut ainsi être disposé à n'importe quel endroit du boîtier sans remettre en cause l'étanchéité du boîtier, il peut en particulier être d isposé au sein d'une zone étanche du boîtier, de façon à réduire l'encombrement du boîtier. During the pegging of the end of the fastening means, in order to deform the piece so as to create a mechanical connection between the cover and the fastening means, the end of the fastener partially melts thanks to the heat supplied during the pegging. The heat provided during the ramol l cut at the extrem ity of the fastening means, but also the continuous reinforcement periphery of the hole d uq uel exceeds the extrem ité of the fastening means. This softening allows the materials constituting the reinforcement and the end of the fastening means to mix with each other, thus creating a weld between the reinforcement and the end of the fastening means. This weld, guaranteed between the two elements, ensures the sealing at the contact zones between the cover (via the reinforcement) and the fixing means. Such a leaktight fastening means can thus be disposed anywhere in the casing without compromising the tightness of the casing, it can in particular be placed within a sealed zone of the casing, so as to reduce encumbrance of the housing.
[ 0013] Outre les caractéristiques principales qui viennent d'être mentionnées dans le paragraphe précédent, le boîtier selon l'invention peut présenter une ou plusieurs caractéristiques complémentaires parmi les suivantes, considérées individuellement ou selon les combinaisons techniquement possibles : In addition to the main features which have just been mentioned in the preceding paragraph, the housing according to the invention may have one or more additional characteristics among the following, considered individually or according to the technically possible combinations:
la hauteur du renfort est au moins égale à la hauteur de l'extrémité du moyen de fixation après bouterollage. On entendra par hauteur de l'extrémité du moyen de fixation après bouterollage, la hauteur maximale de l'extrémité du moyen de fixation après bouterollage. En effet, après bouterollage, l'extrémité du moyen de fixation peut ne pas avoir une hauteur uniforme ;  the height of the reinforcement is at least equal to the height of the end of the fastening means after pegging. The height of the end of the fastening means after basting will be understood to mean the maximum height of the end of the fastening means after jamming. Indeed, after pebble, the end of the fastening means may not have a uniform height;
- l'enceinte comporte un moyen d'étanchéité, ledit moyen d'étanchéité étant configuré pour définir une zone fermée et étanche de l'enceinte . - The enclosure comprises a sealing means, said sealing means being configured to define a closed and sealed zone of the enclosure.

le moyen de fixation est disposé à l'intérieur de ladite zone fermée et étanche de l'enceinte. En disposant le moyen de fixation dans la zone étanche, et non pas à l'extérieur de la zone étanche, l'encombrement du boîtier étanche est avantageusement l imité à l'encombrement seul des éléments que le boîtier étanche est destiné à contenir, sans remettre en cause l'étanchéité du boîtier ;  the fixing means is disposed within said closed and sealed zone of the enclosure. By arranging the fixing means in the sealed zone, and not outside the sealed zone, the bulk of the sealed housing is advantageously limited to the bulk of the elements that the sealed housing is intended to contain, without question the tightness of the case;
- le moyen de fixation est un pion de bouterollage ;  the fixing means is a pegging peg;
ledit moyen de fixation est solidaire de ladite enceinte ;  said fixing means is integral with said enclosure;
le moyen de fixation est un pion s'étendant depuis la surface de l'enceinte ;  the fixing means is a pin extending from the surface of the enclosure;

[0015] L'invention se rapporte aussi à un procédé de solidarisation entre deux pièces caractérisé en ce qu'il comporte :  The invention also relates to a method of joining between two parts characterized in that it comprises:
la fourniture d'un premier élément comprenant un moyen de fixation ; - la fourniture d'un second élément comprenant un trou et un renfort continu en périphérie du trou ;  providing a first member comprising fastening means; - Providing a second element comprising a hole and a continuous reinforcement at the periphery of the hole;

DESCRIPTION DETAILLEE D'UN MODE DE REALISATION DETAILED DESCRIPTION OF AN EMBODIMENT
[ 0020 ] Un couvercle 12 d'un boîtier étanche comportant un trou 121 est visible sur les figures 3A et 3B. Le couvercle 1 2 est muni d'un renfort 122 continu en périphérie du trou 121 . On entend par renfort continu en périphérie du trou, un renfort entourant le trou sans discontinuité. Un tel type de renfort 122 peut être en matériau plastique. Ce renfort 122 peut être une collerette formant une pièce d'un seul tenant avec le couvercle 12. Par exemple, la collerette peut être directement moulée dans la matière du couvercle lors de la fabrication du couvercle 12.  A lid 12 of a sealed housing having a hole 121 is visible in Figures 3A and 3B. The lid January 2 is provided with a reinforcement 122 continuous periphery of the hole 121. Continuous reinforcement is understood to mean the periphery of the hole, a reinforcement surrounding the hole without discontinuity. Such a type of reinforcement 122 may be of plastic material. This reinforcement 122 may be a flange forming an integral part with the cover 12. For example, the flange may be directly molded into the material of the cover during the manufacture of the cover 12.
[ 0021 ] Sur les figures 3A et 3B, un moyen de fixation 1 1 1 de l'enceinte du boîtier est en outre visible (l'enceinte n'est pas visible sur ces figures). Dans cet exemple de réalisation, le moyen de fixation 1 1 1 est un pion de bouterollage. In Figures 3A and 3B, a fixing means 1 1 1 of the enclosure of the housing is further visible (the enclosure is not visible in these figures). In this embodiment, the fastening means January 1 is a pegging peg.
[ 0022 ] Le pion de bouterollage est inséré dans le trou 121 afin de permettre la fixation du couvercle 1 2 à l'enceinte, après bouterollage du pion . L'enceinte (non visible sur ces figures) est solidaire du moyen de fixation, par exemple, en moulant le moyen de fixation sur l'enceinte. The pegging pin is inserted into the hole 121 to allow the attachment of the lid 1 2 to the chamber, after pegging the pin. The enclosure (not visible in these figures) is integral with the fastening means, for example, by molding the fastening means on the enclosure.
[ 0023] Une extrémité 1 1 2 du pion de bouterollage 1 1 1 dépasse du trou 1 21 . Cette extrémité 1 12 peut être, par exemple, en matériau plastique. L'ensemble du moyen de fixation 1 1 1 peut être dans la même matière que l'extrémité 1 12 du moyen de fixation, de façon à faciliter le moulage des éléments.  An end 1 1 2 of the peg 1 1 1 protrudes from the hole 1 21. This end 12 may be, for example, plastic material. The assembly of the fastening means 1 1 1 may be in the same material as the end 1 12 of the fastening means, so as to facilitate the molding of the elements.
[ 0024 ] La figure 3A représente l'extrémité 1 12 avant bouterollage et la figure 3B représente cette même extrémité 1 12 après bouterollage. Lors du bouterollage de l'extrémité 1 12 du moyen de fixation, de façon à déformer ladite extrémité 1 12 du moyen de fixation, de la chaleur est dégagée au niveau de l'extrémité 1 12 afin de permettre la déformation du plastique. La forme arrondie de l'extrémité 1 12 du pion de bouterollage visible à la figure 3B, après bouterollage, n'est pas limitative. Figure 3A shows the end 1 12 before pegging and Figure 3B shows the same end 1 12 after pegging. When pegging the end 1 12 of the fastening means, so as to deform said end 1 12 of the fastening means, heat is released at the end 1 12 to allow the deformation of the plastic. The rounded shape of the end 1 12 of the pegging pin visible in Figure 3B, after pegging, is not limiting.
[ 0025] Lorsq ue l'extrémité du moyen de fixation, dans cet exemple en matériau plastique, est déformable (i.e. lorsque la chaleur dégagée est suffisante pour atteindre une température proche de la température de fusion du plastique), une matrice est disposée au-dessus de l'extrémité 1 1 2 du moyen de fixation. La matrice permet de donner la forme désirée à la pièce bouterollée, ici l'extrémité 1 12 du pion de bouterollage. La forme arrondie, par exemple donnée à l'extrémité 1 1 2 du moyen de fixation visible sur la figure 3B, assure une liaison mécanique entre l'enceinte et le couvercle 12. Le bouterollage peut être, par exemple, du type bouterollage à chaud (déformation du plastique au moyen d'une pièce dégageant de la chaleur, du type thermode) ou à froid (déformation du plastique suite au chauffage du plastique sous l'effet des vibrations d'une sonotrode, la sonotrode ne dégageant pas directement de chaleur). When the end of the fixing means, in this plastic material example, is deformable (ie when the heat generated is sufficient to reach a temperature close to the melting point of the plastic), a matrix is disposed above the end 1 1 2 of the fastening means. The matrix makes it possible to give the desired shape to the riveted piece, here the end 1 12 of the pegging peg. The rounded shape, for example given at the end 1 1 2 of the fixing means visible in FIG. 3B, provides a mechanical connection between the enclosure and the cover 12. The pegging can be, for example, of the type of hot-air basting. (deformation of the plastic by means of a heat-generating part of the thermode type) or cold (deformation of the plastic following the heating of the plastic under the effect of the vibrations of a sonotrode, the sonotrode not releasing heat directly ).
[ 0026] La chaleur dégagée lors du bouterollage au niveau de l'extrémité 1 12 du moyen de fixation fait également fondre au moins partiellement le renfort 122, dans cet exemple de réalisation, en matériau plastique. Cette fusion du matériau plastique du renfort 122 en contact avec une partie de l'extrémité 1 12 du moyen de fixation permet aux matériaux les constituant de se mélanger créant ainsi une soudure 123. La soudure 123, ainsi formée au niveau de l'interface de contact entre le renfort et l'extrémité du moyen de fixation, assure l'étanchéité au niveau du trou 1 21 . La soudure 1 23 assure en outre un renforcement mécanique de la liaison mécanique formée par le bouterollage de l'extrémité 1 12 du moyen de fixation. Ce renforcement mécanique améliore, entre autres, la tenue aux chocs, à l'arrachement, au cisaillement de la liaison mécanique.  The heat generated during the pegging at the end 1 12 of the fastening means also melts at least partially the reinforcement 122, in this embodiment, plastic material. This melting of the plastic material of the reinforcement 122 in contact with a portion of the end 1 12 of the fastening means allows the constituent materials to mix, thereby creating a weld 123. The weld 123 thus formed at the interface of contact between the reinforcement and the end of the fastening means, ensures sealing at the hole 1 21. The weld 1 23 further ensures a mechanical reinforcement of the mechanical connection formed by the pegging of the end 1 12 of the fastening means. This mechanical reinforcement improves, inter alia, the resistance to shocks, tearing, shearing of the mechanical connection.
[ 0027 ] Les matériaux constituant l'extrémité 1 1 2 du moyen de fixation et le renfort 122 peuvent être différents ou identiques.  The materials constituting the end 1 1 2 of the fastening means and the reinforcement 122 may be different or identical.
[ 0028 ] L'extrémité 1 12 du moyen de fixation après bouterollage a une hauteur Ha (visible sur la fig ure 3B) inférieure à la hauteu r avant bouterollage (non référencée sur la figure 3A). Cette variation de hauteur est due à la fusion du matériau plastique constituant l'extrémité 1 12 du moyen de fixation et à sa déformation au moyen de la bouterolle. Afin d'assurer une étanchéité optimale au niveau des zones de contact 2 entre le couvercle (via le renfort 122) et le moyen de fixation 1 1 1 , 1e renfort 122 a une hauteur Hr au moins égale à la hauteur Ha de l'extrémité 1 1 2 du moyen de fixation après bouterollage. Cette hauteur Ha de l'extrémité 1 12 du moyen de fixation après bouterollage est la hauteur maximale de ladite extrémité 1 12. Dans l'exemple illustré à la figure 3B, il s'agit de la hauteur au niveau du centre de l'extrémité 1 12 après bouterollage. The end 1 12 of the fastening means after pegging has a height Ha (visible in Figure 3B) lower than the height before pebbling (not referenced in Figure 3A). This variation in height is due to the melting of the plastic material constituting the end 1 12 of the fixing means and to its deformation by means of the snap. In order to ensure optimum sealing at the contact zones 2 between the cover (via the reinforcement 122) and the fastening means 1 1 1, the reinforcement 122 has a height Hr at least equal to the height Ha of the end 1 1 2 of the fastening means after jamming. This height Ha of the end 1 12 of the fixing means after pegging is the maximum height of said end 1 12. In the example illustrated in FIG. 3B, this is the height at the center of the end 1 12 after jamming.
[0029] L'étanchéité du moyen de fixation entre l'enceinte et le couvercle étant assurée, il est possible de disposer ce moyen de fixation 1 1 1 au sein de la zone étanche du boîtier 1 , tel qu'illustré à la figure 4. Par comparaison entre les figures 1 et 4, il est visible que la taille des pattes de fixation 14 du boîtier 1 à un autre élément est réduite. En effet, le moyen de fixation 1 1 1 entre l'enceinte et le couvercle du boîtier peut être ramené vers l'intérieur du boîtier 1 au sein de la zone étanche 1 1 3 sans remettre en cause l'étanchéité nécessaire au bon fonctionnement des éléments contenus dans cette zone étanche, par exemple une carte électronique. The tightness of the fastening means between the enclosure and the cover being ensured, it is possible to have this fastening means 1 1 1 within the sealed zone of the housing 1, as shown in Figure 4 By comparison between FIGS. 1 and 4, it is apparent that the size of the fixing lugs 14 of the housing 1 to another element is reduced. Indeed, the fastening means 1 1 1 between the enclosure and the housing cover can be returned to the inside of the housing 1 within the sealed zone 1 1 3 without calling into question the tightness necessary for the proper functioning of the elements contained in this sealed zone, for example an electronic card.
[0030] L'invention n'est pas limitée aux modes de réalisation précédemment décrits en référence aux figures et des variantes pourraient être envisagées sans sortir du cadre de l'invention.  The invention is not limited to the embodiments described above with reference to the figures and variants could be envisaged without departing from the scope of the invention.
