Abstract
(EN)
In the system according to the present invention, the casing has at least one wall (2, 20) with one hole (3, 30) and the envelope (5) has at least one through-hole (5b). The system includes a bushing (4) with a cylindrical portion (4a) having an internal surface that is at least partially threaded and an external surface that is at least partially splined; in which the cylindrical portion (4a) of the bushing (4) is inserted into the hole (3, 30) in the wall (2, 20) and is fastened thereto by means of an interference fit; and in which the envelope (5) is fastened by positioning the envelope in contact with the bushing (4) so that a screw (6) can be inserted into the through-hole (5b) and screwed into the internal surface of the cylindrical portion (4a) of the bushing (4).
(FR)
Dans le système selon la présente invention, le boîtier comprend au moins une paroi (2, 20) présentant un trou (3, 30) et une enveloppe (5) comportant au moins un trou traversant (5b). Le système comprend une douille (4) présentant une partie cylindrique (4a) dotée d’une surface intérieure au moins partiellement filetée et d’une surface extérieure au moins partiellement striée, la partie cylindrique (4a) de la douille (4) étant insérée dans le trou (3, 30) de la paroi (2, 20) et fixée dans celui-ci grâce à une relation d’interférence. Pour la fixation de l’enveloppe (5), l’enveloppe est positionnée en contact avec la douille (4), de manière qu’une vis (6) puisse être insérée dans le trou traversant (5b) et vissée dans la surface intérieure de la partie cylindrique (4a) de la douille (4).

No sistema da presente invenção, a carcaça compreende pelo menos uma parede (2, 20) com um furo (3, 30) e o invólucro (5) compreende pelo menos um furo atravessante (5b). O sistema compreende uma bucha (4) tendo uma parte cilíndrica (4a) tendo uma superfície interna pelo menos parcialmente rosqueada e uma superfície externa pelo menos parcialmente estriada; em que a parte cilíndrica (4a) da bucha (4) é inserida no furo (3, 30) da parede (2, 20) e é fixada no mesmo por uma relação de interferência; e em que, para a fixação do invólucro (5), o invólucro é posicionado em contato com a bucha (4), de modo que um parafuso (6) pode ser inserido no furo atravessante (5b) e rosqueado na superfície interna da parte cilíndrica (4a) da bucha (4).
