Abstract

The device for securing and retaining at least one electrical harness in a turbomachine includes: at least one hollow profiled element that extends in one direction and has at least two slots of approximately the same dimension and; and a clamping element intended to retain the at least one harness in position in a manner parallel to the hollow profiled element. The clamping element includes: a touch-and-close tape designed to cooperate with the width of the slots so as to allow it to pass on both sides of the profiled element and; an end stop secured to the tape, the end stop preventing the tape from passing through one of the slots in the profiled element.

First claim

The invention claimed is:

1. A device for securing and retaining at least one electrical harness in a turbomachine, including:
at least one hollow profiled element extending in a direction and including at least two slots of roughly the same dimensions, said at least one hollow profiled element being a cylindrical tube, and;
a clamping element intended to hold in position the at least one harness parallel to the hollow profiled element, said at least one harness to be positioned around a circumference and on an outer surface of the cylindrical tube, which provides a support surface for said at least one harness,
wherein said clamping element includes
a touch-and-close tape adjusted to cooperate with a width of the at least two slots such that the touch-and-close tape is passable either side of the profiled element, the touch-and-close tape including a first face intended to be in contact with a second face of the touch-and-close tape when said at least one electrical harness is held in position by the clamping element, and;
an end stop coupled to the touch-and-close tape and to be pressed against one of the at least two slots, where the end stop has dimensions greater than said one of the at least two slots so that a passage of the end stop through said one of the at least two slots of the profiled element is blocked.

2. The device according to claim 1 , wherein the end stop is positioned at one of the ends of the touch-and-close tape.

3. The device according to claim 1 , wherein the touch-and-close tape is made of a metal type material.

4. The device according to claim 1 , wherein the touch-and-close tape is made of a composite type material.

5. The device according to claim 1 , wherein the at least two slots are positioned such that the at least two slots are diametrically opposite, and roughly facing one another.

6. A fastening system including a device according to claim 1 and at least one harness, wherein the at least one harness is secured and retained by winding the touch-and-close tape around the profiled element and the harness such that a first face of the touch-and-close tape is in contact with a second face of the touch-and-close tape.

7. The fastening system according to claim 6 , wherein the at least one harness is covered with a heat-shrinkable sheath.

8. A turbomachine including at least one pipe secured to the turbomachine, and a device according to claim 1 , where the clamping element enables the at least one harness, the profiled element and the at least one pipe to be securely coupled to one another.

9. The device according to claim 1 , wherein the stop is arranged to be pressed against said one of the at least two slots on the outer surface of the tube by said touch and close tape in order to hold in position the at least one harness parallel to the tube.
