DETAILED DESCRIPTION OF THE INVENTION

(6) In some watches comprising hands, an electrical contact is sufficient or an electrical connection is sufficient for the correct operation of said watch. Although some failures may be detected during the assembling or during a very strict quality control according to the standards of the applicant, unfortunately these failures, despite being rare, may appear during the life of the product and may be detrimental to its longevity.

(7) This electrical contact is established during the assembling of various parts and in particular during a motor module for example.

(8) To this end, the applicant proposes a fastening device 100 for fastening at least one tube 200, preferably at least one pipe 200 and for electrically connecting said at least one tube 200, preferably said at least one pipe 200, to at least one support 300 that may take the form of an electronic board 300 or of an electronic module 300.

(9) According to one aspect of the invention, the applicant proposes a fastening kit 400 grouping these various components, namely, said at least one fastening device 100 as previously mentioned, said at least one tube 200, preferably said at least one pipe 200, and said at least one support 300 so that said fastening device 100 may fasten said at least one tube 200, preferably said at least one pipe 200, to at least one support 300 while minimising the gap between said at least one tube 200, preferably said at least one pipe 200, and said at least one support 300 and by ensuring an electrical contact between said at least one tube 200, preferably said at least one pipe 200, and said at least one support 300.

(10) The latter, illustrated in FIG. 3, comprises at least one electrically conductive surface 310 configured to be electrically connected to said tube 200, preferably to said pipe 200, by means of said at least one electrical conductor 101 of said fastening device 100.

(11) Said fastening device 100, which may be, according to one embodiment shown in FIG. 1, a key 100, comprising at least one admission zone 110, at least one fastening zone 120 and at least one electrical conductor 101.

(12) Said fastening device 100 may fasten, according to a fastening method 500 of which the steps may take place successively and/or simultaneously, said at least one tube 200, preferably at least one pipe 200, to said at least one support 300. According to the needs of the user, it may be that they choose to deposit said to said at least one support 300 on a frame 999. Said frame 999 comprises a hole wherein said at least one tube 200, preferably at least one pipe 200, is placed so as to pass through said frame 999 and said to said at least one support 300, which also comprises an opening. Preferably and in most of the embodiments, said at least one tube 200, preferably at least one pipe 200, comprises at least one bearing member 240, able to take the form of a collar, configured to give to said at least one tube 200, preferably to said at least one pipe 200, a greater stability.

(13) For this, said at least one tube 200, preferably of said at least one pipe 200 is admitted 510 into said at least one admission zone 110 of said at least one fastening device 100, as shown in FIG. 4A.

(14) After its admission 510, FIG. 4B, said at least one fastening device 100 is moved 520 so that said at least one tube 200, preferably said at least one pipe 200, passes from said at least one admission zone 110 to said at least one fastening zone 120.

(15) Indeed, according to one embodiment, said at least one admission zone 110 and said at least one fastening zone 120 are coplanar, so that it is possible to admit 510 said at least one tube 200, preferably said at least one pipe 200, into said at least one admission zone 110 and to move 520 said at least one fastening device 100 in said at least one fastening zone 120 parallel to the plane formed by said at least one admission zone 110 and said at least one fastening zone 120.

(16) Said at least one tube 200 is inserted 530, preferably of said at least one pipe 200 is inserted 530, into said at least one fastening zone 120. Said at least one fastening zone 120 may be entirely or partly delimited by at least one retention member 121 configured to be inserted into at least one groove 220, visible in FIG. 2, and to retain said at least one tube 200, preferably at least one pipe 200. In the embodiment presented in FIG. 1, said at least one fastening zone 120 and said at least one retention member 121 has a “U” or “C” shape in order to enable a better insertion 530 of said at least one tube 200, preferably of said at least one pipe 200.

(17) Said at least one groove 220 is present on said at least one tube 200, preferably at least one pipe 200, in order to cooperate with said at least one fastening zone 120 of said fastening device 100, as previously mentioned. Thus, it is possible to admit 510 said at least one tube 200, preferably said at least one pipe 200, into said at least one admission zone 110 and to insert 530 said at least one tube 200, preferably said at least one pipe 200, into said at least one fastening zone 120, more precisely, to insert 530 said at least one groove 220, preferably being in the form of a recess 220, into said at least one fastening zone 120.

(18) This insertion 530 of said at least one tube 200, preferably of said at least one pipe 200, may be promoted by the elastic deformation of said at least one fastening zone 120. Indeed, said at least one fastening zone 120 may deform or may be less elastically deformable than said at least one admission zone 110 and may fasten 540 said at least one tube 200, preferably said at least one pipe 200, to said at least one support 300 by exerting a force on said at least one tube 200, preferably said at least one pipe 200.

(19) The fastening 540 of said at least one tube 200, preferably of said at least one pipe 200, to said at least one support 300 is thus performed and the electrical connection 550 of said at least one tube 200, preferably of said at least one pipe 200, to said at least one support 300 and the axial clearance between said at least one tube 200, preferably said at least one pipe 200, and said at least one support 300 is minimised and by ensuring a permanent electrical axial contact between said at least one tube 200, preferably said at least one pipe 200, and said at least one support 300.

(20) Moreover, this electrical contact may be enabled by said at least one fastening zone 120 configured to pin said at least one tube 200, preferably said at least one pipe 200, to said at least one support 300, which on the one hand makes it possible to minimise the gap between said at least one tube 200, preferably said at least one pipe 200, and said at least one support 300 and, on the other hand, to promote an electrical contact between said at least one tube 200, preferably said at least one pipe 200, and said at least one support 300.

(21) In order to secure 560 said at least one tube 200, preferably of said at least one pipe 200, to said at least one support 300, said fastening device 100 comprises at least one securing member 140 configured to secure said fastening device 100 to said at least one support 300, preferably to secure said fastening device 100 when said at least one fastening zone 120 fastens said at least one tube 200, preferably said at least one pipe 200, to said at least one support 300.

(22) Said at least one securing member 140, visible in FIG. 1, may be in the form of a catch and protrude with said fastening device 100, preferably, said at least one securing member 140 protrudes in relation to the plane of said at least one admission zone 110 and/or of said at least one fastening zone 120 and may cooperate with a securing zone 340, able to be in the form of notch 340 included on said at least one support 300 and able to lock in radial position said fastening device 100. Indeed, given that said at least one admission zone 110 may deform or may be more elastically deformable than said at least one fastening zone 120, once said at least one tube 200, preferably of said at least one pipe 200, has been fastened in said at least one fastening zone 120, said at least one admission zone 110 elastically deforms in order to enable said at least one securing member 140 to cooperate with said securing zone 340.

(23) According to one embodiment (not shown), said at least one securing member 140 may be coplanar with said at least one admission zone 110 and/or said at least one fastening zone 120.

(24) Independently of the embodiments, said at least one securing member 140 makes it possible to secure said fastening device 100 to said at least one support 300 by limiting the movements of said fastening device 100 and to guarantee the fastening of said at least one tube 200, preferably of said at least one pipe 200, to said at least one support 300.

(25) According to another aspect, said fastening device 100 may comprise at least one stabilising member 130 able to protrude with said fastening device 100 and/or able to delimit said at least one admission zone 110 and/or said at least one fastening zone 120. Preferably, said at least one stabilising member 130 makes the connection between said at least one admission zone 110 and said at least one fastening zone 120, and may enable the elastic deformation of said fastening device 100, and preferentially, makes it possible for said at least one admission zone 110 to deform more elastically than said at least one fastening zone 120 so that said at least one securing member 140 may cooperate with said securing zone 340.

(26) Said at least one stabilising member 130 may be in the form of a branch extending longitudinally, laterally and/or perpendicularly and is configured to stabilise said fastening device 100, preferably to stabilise said fastening device 100 when said at least one fastening zone 120 fastens said at least one tube 200, preferably said at least one pipe 200, to said at least one support 300. Indeed, said at least one stabilising member 130 may be at least one return member 130 and be curved towards said at least one support 300 so as to push said at least one tube 200, preferably said at least one pipe 200, via said fastening device 100 of said at least one support 300 in the manner of a spring. Said at least one bearing member 240, being disposed along said at least one tube 200, preferably said at least one pipe 200, and distant from said at least one groove 220, sandwiches said frame 999 and/or said at least one support 300 with said fastening device 100. The spring effect of said at least one stabilising member 130 creates a pinning force that guarantees the pinning of at least one tube 200, preferably of said at least one pipe 200, against said frame 999 and/or said at least one support 300 with said fastening device 100. This pinning may guarantee the perpendicularity of said at least one tube 200, preferably of said at least one pipe 200, which makes it possible to guarantee a correct operation of the wheels that will pivot on said at least one tube 200, preferably said at least one pipe 200, see FIG. 4C.

(27) Moreover, according to one embodiment shown in FIG. 1, said at least one stabilising member 130 and said at least one securing member 140 may be combined and may be said at least one electrical conductor 101.

(28) Thus thanks to the invention, said fastening device 100 has a greater vertical compliance and also thanks to its shape of ensuring an electrical contact. Moreover, said at least one support 300 includes a notch in order to orient said fastening device 100 in rotation about the tube and to lock said fastening device 100 in radial position. In this way the electrical contact is more or less covered by said fastening device 100, and the capacitive environment of the electrical contact remains repeatable once said fastening kit 400 has been mounted.
