Abstract

An electronic module designed to be incorporated in a tire, comprising a functional device, a support and at least one device for electrically connecting a wire and a device for mechanically fixing the wire, separate from the electrical connection device, for mechanically fixing the wire to the support.

Claims

1. An electronic module designed to be incorporated in a deformable element such as a tire, a patch for tire or a deformable element used in the suspension of a vehicle, comprising a functional device fixed to a support and at least one device for electrically connecting a wire to the functional device,

comprising a device for mechanically fixing the wire, separate from the electrical connection device, for mechanically fixing the wire to the support.

2. The module according to claim 1, in which the device for mechanically fixing the wire comprises crimping means.

3. The module according to claim 1, in which the device for mechanically fixing the wire comprises snap-fitting means.

4. The module according to claim 1, in which the device for mechanically fixing the wire comprises gluing means.

5. The module according to claim 1, comprising, for the wire, a passage terminating at the electrical connection device, the mechanical fixing device being positioned on the passage, upstream of the electrical connection device.

6. The module according to claim 1, in which the mechanical fixing device is shaped to be applied to an outer insulation of the wire.

7. An electronic system designed to be incorporated in a tire, comprising a module according to claim 1 and at least one wire comprising a section linked to the module and a free section, the linked section of the wire being connected to the electrical connection device and fixed to the module by means of the mechanical fixing device.

8. The system according to claim 7, in which the wire is connected to the electrical connection device by soldering.

9. The system according to claim 7, also comprising a jacket protecting the module and the linked section of the wire.

10. The system according to claim 9, in which the jacket also protects a part of the free section of the wire so as to form means of guiding the free section.

11. The system according to claim 10, in which the guiding means guide the free section in a rectilinear manner.

12. The system according to claim 11, comprising two wires connected to the module, in which the jacket is shaped in such a way that the free sections of the two wires are roughly coaxial.

13. The system according to claim 10, in which the guiding means are of increasing rigidity in the direction of the module.

14. The system according to claim 9, in which the jacket is made of a resin molded onto the module and the wire.

15. The system according to claim 9, in which the jacket is made up of several layers of resins of decreasing rigidity successively molded onto the module and the wire.

16. The system according to claim 9, in which the jacket comprises a case containing the module and the resin filling the case.

17. The system according to claim 16, in which the case is formed by two half shells.

18. The system according to claim 9, in which the jacket is roughly in the shape of a roller.

19. A vehicle tire, in which is incorporated an electronic system according to claim 7.

20. A method of obtaining a system according to claim 8, wherein the wire is fixed before it is soldered.
