Description

Title of the invention: Mechanism, use of the mechanism, for placing, on a wall of a device, an assembly comprising a support and a component mounted on the surface of the support, and device comprising said mechanism, and said assembly.

[0001] The present invention relates to the field of electronic terminals, and in particular to the assembly of surface-mounted components.

[0002] It is known to mount a surface-mounted component, for example a gasket associated with a MEMS microphone, on a support, for example an electronic board or a printed circuit board, using a flange and a screw to ensure support of the component against an outer cover of the device, and in particular, in the case of a gasket, to ensure compression of a gasket against the outer cover which may include a channel, for example an acoustic channel.

[0003] Mounting with a flange and a screw requires several steps and is complex to implement. Furthermore, during mounting, significant precautions must be taken to avoid damaging the surface-mounted component. In addition, sufficient space must be provided during mounting to allow the use of mounting tools in the mounting area.

[0004] The invention therefore aims to provide a solution to all or part of these problems.

[0005] The present invention relates to a mechanism for placing, on a target location of a wall of a device, an assembly comprising a support and a component mounted on the surface of the support:

[0006] - at least one elastic leg attached to the wall by a connecting portion of the at least one elastic tab, the at least one elastic tab comprising a free bearing portion, the at least one tab being configured to be put under tension when the bearing portion is moved away from the wall, so as to permit insertion of the assembly between the bearing portion of the at least one elastic tab and the wall in a defined insertion direction to bring the surface-mounted component of the support opposite the target location;

[0007] - at least one clearance face placed projecting from the wall in such a way that at least a part of the support rests on at least one clearance face during the insertion of the assembly, the projection from the wall of at least one clearance face being dimensioned so that, when at least a part the support rests on at least one clearance face, a gap between the support and the wall allows the surface-mounted component of the support to pass, without contact with the wall during the insertion of the assembly, the at least one clearance face being further positioned on the wall and dimensioned in the direction of insertion so that, when the surface-mounted component of the support is opposite the target location, at least a part of the support is no longer resting on the at least one clearance face, and so that a release of the at least one elastic tab has the effect of pressing the support against the wall, the surface-mounted component of the support being pressed against the target location.

[0008] According to these provisions, the assembly requires no flange, screw, or any other tool. The component only comes into contact with the wall once the assembly is complete, by pressing against the wall at the target location. It is not at risk of being damaged by friction against the wall during assembly.

[0009] According to one embodiment, the invention comprises one or more of the following features, alone or in a technically acceptable combination.

[0010] According to one possibility, the mechanism includes a shoulder positioned after the clearance face in the insertion direction, so that, when the surface-mounted component of the support is facing the target location, at least a portion of the support is disposed beyond the shoulder.

[0011] The shoulder marks the end of the support on the release face. The shoulder also prevents the support from emerging in the opposite direction to the insertion direction.

[0012] The mechanism includes a bearing face that is offset from the edge of the clearance face towards the wall and extends along the insertion direction. When at least a portion of the support is no longer bearing against the clearance face, it bears against the bearing face.

[0013] According to one possibility, the mechanism includes a stop transverse to the insertion direction and positioned beyond the shoulder in the insertion direction.

[0014] The stop is positioned beyond the bearing face and prevents the insertion of the support in the insertion direction. The part(s) of the support are thus housed in their final position between the shoulder and the stop, against the bearing face.

[0015] The relative distance between the bearing face and the wall at the target location can be used to define the bearing level of the surface-mounted component against the target location.

[0016] According to one possibility, the mechanism comprises two release faces, such that two parts of the support rest respectively on each of the two faces of clearance during assembly insertion, the two clearance faces being positioned on the wall at a distance from each other greater than a dimension of the surface-mounted component, said dimension being determined transversely to the insertion direction, so that, the surface-mounted component of the assembly being attached to a portion of the support located between the two parts of the support, said portion of the support passes between the two clearance faces during assembly insertion.

[0017] According to these provisions, the stability of the support resting on two distinct parts, and consequently the stability of the assembly as a whole, is better ensured during the insertion of the assembly, and the passage of the surface-mounted component between the two clearance faces, without contact with the wall, is facilitated.

[0018] According to one possibility, the mechanism comprises two elastic tabs positioned on the wall at a distance from each other greater than a dimension of the surface-mounted component of the support, said dimension being determined transversely to the axis in the direction of insertion, so that the surface-mounted component of the assembly passes between the two elastic tabs during the insertion of the assembly.

[0019] According to these provisions, the stability of the support and consequently the stability of the assembly as a whole is better ensured during the insertion of the assembly.

[0020] The present invention also relates to a device comprising a wall with a target location, the wall comprising a mechanism as described above.

[0021] According to one possibility, the device comprises an assembly, the assembly comprising a support and a component mounted on the surface of the support.

[0022] According to one possibility, the surface-mounted component protrudes from the surface of the support.

[0023] According to one possibility, the support is a printed circuit board.

[0024] According to one possibility, the target location includes a through hole.

[0025] According to one possibility, the surface-mounted component includes a seal, such as a acoustic joint.

[0026] According to one possibility, the mechanism includes the assembly further includes a microphone.

[0027] According to one possibility, the microphone is a microelectromechanical system type microphone, called MEMS.

[0028] According to one possibility, the support is functionally coupled to the microphone.

[0029] According to one possibility, the acoustic seal forms an internal tubular conduit around of a joint axis.

[0030] According to one possibility, the acoustic joint is compressible along the axis of the joint.

[0031] According to one possibility, the acoustic seal is fixed by one side of the acoustic seal to the support so that said internal conduit is acoustically coupled to the microphone by one end of said internal conduit, another end of said internal conduit being configured to be acoustically coupled with a hole through the wall, the axis of the acoustic seal being aligned with an axis of the through hole, so as to form, with the through hole, an acoustic channel configured to conduct sound between one side of the wall and the microphone of the assembly placed on another side of the wall.

[0032] According to one possibility, when the axis of the acoustic seal is aligned with the axis of the through hole, at least a portion of the support is no longer bearing on at least one clearance face. Thus, releasing the at least one elastic tab causes the support to press against the wall, compressing the acoustic seal along the axis of the acoustic seal.

[0033] According to one possibility, the insertion direction is transverse to the axis of the joint.

[0034] According to one possibility, the insertion direction being defined to bring the component the axis of the acoustic joint in alignment with the axis of the through hole

[0035] According to one possibility, the projection of at least one clearance face relative to the wall is dimensioned so that, when at least one part of the support rests on at least one clearance face, a gap between the support and the wall allows the acoustic seal, uncompressed, to pass, without contact with the wall during the insertion of the assembly, the at least one clearance face being further positioned on the wall and dimensioned in the direction of insertion so that, when the axis of the acoustic seal is aligned with the axis of the through hole, at least one part of the support is no longer resting on at least one clearance face, and so that a release of at least one elastic tab has the effect of pressing the support against the wall, compressing the acoustic seal in the direction of the axis of the acoustic seal against the target location and the through hole.

[0036] Thanks to these provisions, it is possible to use a simple, straight acoustic joint, and the acoustic channel is more efficient. Indeed, depending on the orientation of the acoustic channel and the perpendicular direction of assembly of the parts, the known method of mounting the MEMS microphone according to the prior art required, in addition to a flange and screws, a specific, non-standard joint when the channel forms a 90° bend, which complicated the development of the microphone function because of the acoustic reverberations caused by the bend, and which could impair the acoustic performance of the final assembly.

[0037] According to one possibility, the printed circuit board has a main extension in a plane transverse to the axis of the joint.

[0038] According to one possibility, the axis of the joint is maintained transversely to an extension plane of the wall.

[0039] According to one possibility, at least one elastic tab, when under tension, pulls the printed circuit board towards the wall. In particular, at least one elastic tab pulls a main extension plane of the printed circuit board towards the extension plane of the wall.

[0040] According to one possibility, the axis of the joint is maintained transversely to an extension plane of the wall.

[0041] According to one possibility, at least one elastic tab under tension brings a plane of the main extension of the printed circuit board towards an extension plane of the wall.

[0042] According to other possibilities, the surface-mounted component of the support may include an LED, or a coil or other inductive component intended to be positioned against a target location on a wall.

[0043] According to one possibility, the device is an electronic device, for example a mobile terminal.

[0044] The present invention also relates to a use of the mechanism as described according to one of the possibilities described above, for obtaining a device according to one of the possibilities described above, by implementing an assembly insertion step between the free portion separated from at least one tensioned elastic tab and the wall, in an insertion direction defined to bring the surface-mounted component of the support opposite the target location, and such that at least a part of the support rests on at least one clearance face during the assembly insertion step, the protrusion of at least one clearance face being dimensioned so that, when at least a part of the support rests on at least one clearance face, a gap between the support and the wall allows the surface-mounted component to pass, without contacting the wall during the assembly insertion,at least one clearance face being further positioned on the wall and dimensioned, in the direction of insertion, so that, when the surface-mounted component of the support is opposite the target location, at least a part of the support is no longer bearing on at least one clearance face, and so that a release of at least one elastic tab has the effect of pressing the support against the wall, the surface-mounted component of the support being pressed against the target location.

[0045] According to one aspect, the invention relates to a device according to one of the embodiments described above, obtained by using the mechanism, according to one of the embodiments described above.

[0046] For better understanding, an embodiment and / or implementation of the invention is described with reference to the accompanying drawings, which represent, by way of non-limiting example, one embodiment or implementation of a device and / or method according to the invention. The same references on the drawings refer to similar elements or elements with similar functions.

[0048] [Fig.2] is another representation of the mechanism of [Fig.1], during an insertion of the assembly between the legs and the release faces of the mechanism.

[0049] [Fig.3] is another representation of the mechanism of [Fig.1], at the end of an insertion of the assembly between the legs and the release faces of the mechanism.

[0050] [Fig.4] is another perspective representation according to a cutting plane of the mechanism of [Fig.1], at the end of an insertion of the assembly between the tabs and the release faces of the mechanism, the assembly thus being placed, in its final configuration, on the wall of the housing.

[0051] [Fig.5] is a schematic representation of the step of using the mechanism according to an embodiment of the invention, to set up the assembly on a wall of a device.

[0052] The invention relates to a mechanism 1 for mounting, on a wall 16 of a device, an assembly 10 comprising a support 11 and a component mounted on the surface of the support 13. In particular, in the embodiment shown in the figures, the support is a printed circuit board 11 and the surface-mounted component is a gasket 13. It should be noted that the gasket 13 can, for example, be an acoustic gasket or a sealing gasket. In the example described, the gasket 13 is an acoustic gasket. The assembly further includes a microphone 12. The device can be a smartphone, a mobile terminal, computer equipment, etc. In particular, in the example shown in the figures, it is a device equipped with a microphone for capturing sound. The microphone is, for example, a microelectromechanical system microphone, also called a MEMS. The acoustic gasket 13 forms an internal tubular conduit 14, visible in [Fig.4], around an axis A of the seal 13, said acoustic seal 13 being compressible along the axis A of the seal 13; [Fig.4] represents, in perspective and in section, the assembly 10 in its final configuration, i.e. once it has been placed on the wall 16 of the housing of the device; the acoustic seal 13, in this final configuration of the assembly 10, is compressed.

[0053] Before the assembly 10 is put in its final configuration, the acoustic seal 13, fixed by one side of the acoustic seal 13 to the printed circuit board 11, is relaxed along the axis A, so that it occupies a larger volume along this axis A than it will ultimately occupy in its final configuration, in which it is compressed between the printed circuit board 11 and the wall 16. It is important that during the installation of the assembly the acoustic seal should not be damaged or torn off by friction against the wall 16 in particular.

[0054] As stated above, the acoustic seal 13 is fixed by one side of the acoustic seal 13 to the printed circuit board 11, so that the internal conduit 14 is acoustically coupled to the microphone 12 by one end of said internal conduit 14; another end of said internal conduit 14 is configured to be acoustically coupled, in the final configuration of the assembly 10, with a hole 15 through the wall 16, the axis A of the acoustic seal 13 being aligned with an axis of the through hole 15, so as to form, with the through hole 15, a channel, in particular an acoustic channel 14, 15 configured to conduct sound between one side of the wall and the microphone 12 of the assembly 10 placed on another side of the wall 16, as shown in [Fig.4].

[0055] In addition, the printed circuit 11 is functionally coupled to the microphone 11, so as to be able to receive and process the acoustic signals generated by the microphone 12, representative of a sound received by the microphone 12.

[0056] The printed circuit board connects a main extension in a plane transverse to the axis A of the joint. In other words, the joint extends more or less, depending on whether it is compressed or not, along the axis A transverse to the plane of the main extension of the printed circuit board 11.

[0057] Mechanism 1, according to one embodiment of the invention, comprises: - at least one elastic leg 2, 3 attached to the wall 16 by a portion 2', 3' of the at least one elastic leg 2, 3; At least one elastic tab 2, 3 includes another free portion 2”, 3”, the at least one tab 2, 3 being configured to be tensioned when the other portion 2”, 3” is moved away from the wall 16, for example along a movement direction DE shown in [Fig.2], so as to allow insertion of the assembly 10 between the free portion of at least one elastic tab 2, 3 and the wall 16 along an insertion direction DI transverse to the axis A of the acoustic seal 13, the axis of the seal A being maintained transversely to an extension plane of the wall 16. Thus, the main extension plane of the printed circuit board 11 is brought, by the tensioned at least one elastic tab 2, 3, towards said extension plane of the wall 16.

[0058] The direction of the insertion DI, besides being transverse to the axis A of the acoustic joint 13, is defined to bring the axis A of the acoustic joint 13 into alignment with the axis of the through hole 15.

[0059] The mechanism 1, according to one embodiment of the invention, further comprises at least one clearance face 4, 5 projecting from the wall 16 such that at least a portion of the printed circuit board 11 rests against at least one clearance face 4, 5 during the insertion, described above, of the assembly 10. The at least a clearance face may include two clearance faces 4, 5, as shown in [Fig.1], to promote stability of the printed circuit board 11 which thus has two API, AP2 supporting parts on each of the two clearance faces 4, 5, on either side of the microphone 12 and the acoustic joint 13, as shown in [Fig.2].

[0060] The projection, relative to the wall 16, of at least one clearance face 4, 5 is dimensioned so that, when at least a part of the printed circuit board 11 is in API, AP2 support on at least one clearance face 4, 5, a gap between the printed circuit board 11 and the wall 16 allows the acoustic seal 13, uncompressed, to pass, without contact with the wall 16 during the insertion of the assembly 10.

[0061] According to one embodiment, the mechanism 1 comprises two clearance faces 4, 5, such that two parts of the printed circuit board 11 rest respectively on each of the two clearance faces 4, 5 during the insertion of the assembly 10. The two clearance faces 4, 5 are positioned on the wall 16 at a distance from each other greater than a dimension of the microphone 12 and the acoustic seal 13, said dimension being considered transverse to the axis A of the acoustic seal 13 and to the insertion direction DI, such that, the microphone 12 and the acoustic seal 13 of the assembly 10 being attached to a portion of the printed circuit board 11 located between said two parts of the printed circuit board 11, said portion of the printed circuit board 11 passes between the two clearance faces during the insertion of the assembly 10.

[0062] Thus, the stability of the printed circuit board supported on two separate parts, and consequently the stability of the assembly as a whole, is better ensured during the insertion of the assembly, and the passage of the acoustic seal between the two clearance faces, without contact with the wall, is facilitated.

[0063] In particular, the mechanism 1 may advantageously include two elastic tabs 2, 3 positioned on the wall 16 spaced apart by a sufficient distance so that the microphone 12 of the assembly 10 passes between the two elastic tabs 2, 3 during the insertion of the assembly 10.

[0064] Thus, the stability of the printed circuit board and consequently the stability of the assembly as a whole is better ensured during the insertion of the assembly, and the insertion of the assembly is facilitated.

[0065] The clearance face(s) 4, 5 is / are further positioned on the wall 16 and dimensioned, in the direction of the insertion DI, so that, when the axis A of the acoustic seal 13 is aligned with the axis of the through hole 15, i.e., when the assembly reaches its final position, the part(s) of the printed circuit board 11 is / are no longer in contact with the clearance face(s) 4, 5; in other words, the positioning on the wall and the dimensioning, in the direction of the insertion DI, of the clearance face(s) 4, 5, determines a support end FAP of the part(s) of the printed circuit board 11 on the clearance face(s) 4, 5, as shown in [Fig.3]; so that a release, along a release direction DET opposite to the separation direction DE, of at least one elastic tab 2, 3 has the effect of pressing the printed circuit board 11 against the wall 16 by compressing the acoustic seal 13 in the direction of the axis A of the acoustic seal 13, in other words along a compression direction DC parallel to the axis A.

[0066] The mechanism 1 includes a shoulder 17 visible in [Fig. 3], positioned after the clearance face in the insertion direction, so as to materialize the end of the FAP support. Thus, when the seal 13 is opposite the target location, at least a portion of the support 11 is disposed beyond the shoulder 17 in the insertion direction.

[0067] The mechanism includes a bearing face 18 visible in [Fig. 2] which is offset from the edge of the clearance face towards the wall 16 and extends along the insertion direction DI. When at least a portion of the support is no longer bearing against the clearance face, it bears against the bearing face 18. In the embodiment shown in the figures, two bearing faces are arranged on either side of the target location 15.

[0068] Beyond the bearing face, the mechanism includes a stop 19 transverse to the insertion direction DI. The stop 19 prevents the insertion of the support in the insertion direction. The part(s) of the support 11 are thus housed in their final position between the shoulder 17 and the stop 19, against the bearing face 18.

[0069] The distance between the bearing face 18 and the wall 16 at the target location 15 defines the compression level of the joint 13.

[0070] According to these provisions, the assembly requires neither flange, nor screw, nor any other tool, the acoustic seal is a simple, non-bent seal, and the acoustic channel is more efficient.

[0071] According to one aspect, the invention relates to a device comprising a wall 16 with a through hole 15, the wall 16 comprising a mechanism 1 according to one of the embodiments described above, for example electronic equipment or a mobile terminal.

[0072] More particularly, the invention relates to a device comprising an assembly 10 as described above, the printed circuit 11 of the assembly being pressed against the wall 16, by at least one elastic tab 2, 3 of the mechanism 1, compressing the acoustic seal 13 in the direction of the axis A of the acoustic seal 13.

[0073] According to another aspect, the invention relates to a use 100 of the mechanism 1 according to one of the embodiments described above, for placing, on a wall 16 of a device, the assembly 10 described above, and thus for obtaining the device previously described, in which the printed circuit 11 of the assembly is pressed against the wall 16, by at least one elastic tab 2, 3 of the mechanism 1, compressing the acoustic seal 13 in the direction of the axis A of the acoustic seal 13; said use 100 of the mechanism 1 includes the implementation of an insertion step 101 of the assembly 10 between the free portion set apart from at least one elastic tab 2, 3 of the mechanism 1.

[0074] According to one aspect, the invention relates to a device obtained by the use 100 of the mechanism 1, for example electronic equipment or a mobile terminal.

[0075] According to other possibilities, the surface-mounted component of the support may include an LED, or a coil or other inductive component intended to be positioned against a target location on a wall.
