Waterproof monitoring device

Abstract

A watertight monitoring device comprising a housing forming an internal volume (V16) and an electronic circuit board (18) disposed within the housing. The housing has a lower shell (26) and an upper shell (24), juxtaposed along a principal axis (Z) and assembled together. The device includes a sealing gasket (46) between the lower shell (26) and the upper shell (24), and a closure system comprising at least one lower lug (30) belonging to the lower shell, at least one upper lug (28) belonging to the upper shell, and at least one operating member (32), each cooperating with one lower lug and one upper lug.Actuating at least one operating member from an unlocked position to a locked position causes the lower (30) and upper (28) lugs to move closer together, resulting in a translation of the shells towards each other and compression of the seal between the shells.

2. Monitoring device (12) according to claim 1, wherein the or each operating member (32) comprises: - a housing (34) for receiving a first lug (28, 30) among the upper lug (28) and the lower lug (30) associated with this operating member, and - a groove (36) for guiding the second lug (28, 30) among the upper lug (28) and the lower lug (30) associated with this operating member, in which the or each operating member (32) is rotatable about the first lug (28) associated with this operating member, and in which the or each operating member (32) is configured to transform a rotational movement of the operating member into a translational movement of the second lug (28, 30) associated with this operating member along the main axis (Z).

3. Monitoring device (12) according to one of claims 1 and 2, in which the closing system of the monitoring device (12) comprises at least two lower lugs (30), at least two upper lugs (28) and at least two operating members (32).

4. A monitoring device (12) according to claim 3, wherein the monitoring device (12) comprises two operating members (32) and a handle (38) connecting the two operating members (32), and wherein actuation of the handle causes actuation of the two operating members.

5. Monitoring device (12) according to claim 4, wherein the handle (38) is removable, wherein each operating member (32) has a receiving cavity (40) for the handle, and wherein the receiving cavity of each operating member is configured to receive a spur (86) belonging to the support (10), allowing the monitoring device (12) to be attached to the support (10).

6. A monitoring device (12) according to any one of claims 1 to 5, wherein the seal (46) comprises at least one anti-infiltration barrier (64) configured to prevent the infiltration of water between the upper shell (24) and the lower shell (26), and comprises a dust barrier (60), configured to prevent the passage of dust between the upper shell (24) and the lower hull (26).

7. Monitoring device (12) according to claim 6, wherein the at least one anti-infiltration barrier (64) is compressed between an outer face (54) of a first shell (24, 26) among the upper shell (24) and the lower shell (26), the outer face (54) being directed away from the interior volume (V16) of the housing (16), and an inner face (56) of the second shell (24, 26) among the upper shell (24) and the lower shell (26), the inner face being directed towards the interior volume of the housing, and wherein the dust barrier (60) is compressed between a bearing face (62) of the first shell and an end (58) of the second shell, the bearing face being perpendicular to the main axis (Z).

8. A monitoring device (12) according to claim 7, wherein the second shell (24) covers the seal (46).

9. A monitoring device (12) according to any one of claims 1 to 8, wherein the monitoring device comprises one or more connection elements (22), each connection element being fixed to the housing and connected to the electronic card (18), and wherein the lower shell (26) comprises: - an extension (70), extending along the main axis (Z) opposite the upper shell (24), the extension delimiting the interior volume (VI6) of the housing (16), the connection elements (22) being fixed to the extension (70), and - a skirt (74), extending along the main axis (Z) opposite the upper shell, the skirt extending at least as far as an end wall (72) of the extension (70), along the main axis (Z), the skirt surrounding the connection elements (22) fixed to the extension (70), and wherein the extension (70) and the skirt (74) form between them a complementary sealing volume (V74),the connection elements (22) being arranged in the complementary sealing volume.,
