Abstract

A rotary electric machine has a machine casing and a terminal box fitted to the casing, the terminal box having a base part, the latter defining at least: a fixing zone for fixing at least one electronic module, this fixing zone having one or more support elements for receiving fasteners for fixing the module or modules, an electrical connection zone, the latter having at least one block of material for receiving at least one electrical connection element, the support element or elements and the block or blocks of material being molded as a single piece with the base part.

First claim

The invention claimed is:

1. A rotary electric machine comprising:
a machine casing; and
a terminal box fitted to the casing, the terminal box comprising a base part, the base part defining at least:
a fixing zone for fixing at least one electronic module, this fixing zone comprising one or more support elements for receiving fasteners for fixing the module or modules, and
an electrical connection zone, the electrical connection zone comprising at least one block of material for receiving at least one electrical connection element,
the at least one electronic module being connected to electrical conductors of the rotary electric machine via the at least one electrical connection element, and
the support element or elements and the block or blocks of material being moulded as a single piece with the base part.

2. The rotary electric machine according to claim 1 , the support element or elements being pre-holed.

3. The rotary electric machine according to claim 2 , the support element or elements comprising at least one extra hole.

4. The rotary electric machine according to claim 2 , the support element or elements comprising holes distributed over substantially their entire length.

5. The rotary electric machine according to claim 1 , the fasteners comprising clip nuts.

6. The rotary electric machine according to claim 1 , the or at least one of the electronic modules being connected to electrical conductors of the rotary electric machine.

7. The rotary electric machine according to claim 6 , the electronic module or modules being chosen from voltage regulators and speed variators.

8. The rotary electric machine according to claim 1 , the connection zone comprising a plurality of blocks of material arranged at regular intervals in at least one direction.

9. The rotary electric machine according to claim 8 , the plurality of blocks of material being arranged at regular intervals in two mutually perpendicular directions.

10. The rotary electric machine according to claim 1 , the electrical connection element or elements comprising threaded metal inserts.

11. The rotary electric machine according to claim 10 , the threaded metal inserts being overmoulded in the base part.

12. The rotary electric machine according to claim 10 , the threaded metal inserts being female threaded inserts designed to accept screws or threaded studs.

13. The rotary electric machine according to claim 12 , the screws or threaded studs being hexagon socket headless screws of the Hc type.

14. The rotary electric machine according to claim 1 , the connecting zone being central.

15. The rotary electric machine according to claim 14 , the base part defining at least two fixing zones positioned one on each side of the central connecting zone.

16. The rotary electric machine according to claim 15 , the two fixing zones being positioned on the lateral sides of the base part.

17. The rotary electric machine according to claim 1 , comprising a cover fixed to the base part.

18. The rotary electric machine according to claim 17 , the cover comprising at least one removable individual panel that can be detached from the terminal box without fully removing the cover.

19. The rotary electric machine according to claim 17 , the cover comprising front and rear panels, lateral panels and a lid, all these elements being removable relative to one another.

20. The rotary electric machine according to claim 17 , the base part comprising housings to receive fasteners that fix the cover to the base part.

21. The rotary electric machine according to claim 17 , the cover being made of metal.

22. The rotary electric machine according to claim 1 , the base part being moulded in a thermoplastic material.

23. The rotary electric machine according to claim 1 having no external electrical plug for electrical connection.

24. A rotary electric machine comprising:
a machine casing; and
a terminal box fitted to the casing, the terminal box comprising a base part, the base part defining at least:
a fixing zone in which at least one electronic module is fixed, this fixing zone comprising one or more support elements for receiving fasteners by which the at least one module is fixed, the one or more support elements being pre-holed and comprising at least one extra-hole once the at least one module is in place, and
an electrical connection zone, the electrical connection zone comprising at least one block of material for receiving at least one electrical connection element,
the one or more support elements and the at least one block of material being moulded as a single piece with the base part.
