Turbomachine distributor comprising a thermal protection sheet with a radial stop, and associated thermal protection sheet

1. A distributor for a turbomachine, or a low-pressure distributor, to be mounted in a housing, comprising:

a plurality of segments circumferentially distributed around an axis of rotation of the turbomachine;

a plurality of anti-rotation pins, each of which is mounted both on a segment of the distributor and on the housing; and

a thermal protection metal sheet, positioned between the housing and the segments of the distributor, comprising a plurality of tabs, each tab bearing against an anti-rotation pin;

wherein the plurality of tabs of the thermal protection metal sheet comprises at least one axial tab radially abutting against a radially inward face of a first anti-rotation pin, and at least one radial tab axially abutting against an upstream face of a second anti-rotation pin.

2. The distributor according to claim 1 , wherein the thermal protection metal sheet comprises a plurality of the axial tabs and the radial tabs.

3. The distributor according to claim 1 , wherein the number of the radial tabs and the number of the axial tabs is equal.

4. The distributor according to claim 1 , wherein the radial tabs and the axial tabs alternate along the thermal protection metal sheet, around the axis of rotation of the turbomachine, and are separated by an indentation, or with removal of material.

5. The distributor according to claim 1 , wherein the at least one axial tab is at a distance from the first anti-rotation pin when the turbomachine is at rest.
