Abstract
An electronic system (1000) having a member (10) and a retaining device (510). The retaining device has a base (511), a retaining wall (512) extending from the base (511) as far as an edge (513) and defining an open volume (520) that accommodates the member (10). The volume (520) having an opening (516) delimited by the edge (513). The member (10) having a housing (12) circumscribed inside a cylinder (17) having an axis of revolution (15); and wherein the retaining wall has a projecting element (550) radially on the outside of the free edge (513), extending over a thickness (e) along the axis of revolution (15), and the housing (12) has a groove (51) defining a second volume (52) which is able to accommodate the projecting element (550) of the retaining wall (512).
Claims15
An electronic system comprising an electronic member and a retaining device for retaining the electronic member and able to be secured to a wall of the tire casing, said retaining device comprising:
- a base that is able to be secured to the wall of the tire casing via an external surface,
- a closed retaining wall, which is able to retain said electronic member, extending from the base as far as a free edge and defining, with said base, an open volume;
- said volume, which is able to accommodate at least a part of said electronic member, being defined by an internal surface of said base and by an internal surface of said retaining wall, and having an opening, delimited by the free edge of said retaining wall, which is able to deform for the insertion of said electronic member into said volume;
- said electronic member comprising a protective housing defining an outer surface circumscribed inside a cylinder of which the axis of revolution is perpendicular to the median plane of the external surface of the base of said retaining device and which is delimited by two parallel planes;
- and
- wherein the retaining wall comprises a projecting element radially on the outside of the free edge with respect to the axis of revolution and extending towards the volume of the retaining device over a thickness (e) in the direction of the axis of revolution of the cylinder circumscribing the protective housing, wherein the outer surface of the protective housing comprises a continuous and closed groove radially on the outside of the projection of the free edge of the retaining wall onto the outer surface along the direction of the axis of revolution of the cylinder circumscribing the protective housing and extending over an axial distance (e′), wherein the groove defines a second volume which is able to accommodate the projecting element and wherein the projecting element extends over a radial distance (rS) comprised in the radial extent (rR) of the groove with respect to the axis of revolution.
