Abstract

A wire support member for supporting the wiring of an environmental control system. The wire support member has a base edge, a first edge, and a second edge, the first and second edges form a V-shaped apex opposite the base edge. The ratios of the diameter of a first fastener opening through the wire support member to a length from the center of the first fastener opening to the first edge, and of the diameter of the first fastener opening to a length from the center of the first fastener opening to the second edge optimize the routing and support for the wiring.

First claim

The invention claimed is:

1. A wire support member for an environmental control system, the wire support member comprising:
a first side and a second side;
a first edge, a second edge, and a base edge, the first edge and the second edge forming a V-shaped apex opposite the base edge;
a first fastener opening having a center C and a diameter D 1 , a second fastener opening, and a third fastener opening, the first second and third fastener openings extending from the first side to the second side;
a length L 1 from the center C to the first edge and a length L 2 from the center C to the second edge; and
wherein a ratio of length L 1 to diameter D 1 is between 2.0 and 2.3.

2. The wire support member of claim 1 , wherein length L 1 is between 0.860 inches (2.184 centimeters) and 0.920 inches (2.337 centimeters) and diameter D 1 is between 0.401 inches (1.018 centimeters) and 0.411 inches (1.044 centimeters).

3. The wire support member of claim 1 , wherein a ratio of length L 2 to diameter D 1 is between 1.1 and 1.4.

4. The wire support member of claim 3 , wherein the length L 2 is between 0.470 (1.193 centimeters) inches and 0.530 inches (1.347 centimeters) and diameter D 1 is between 0.401 inches (1.018 centimeters) and 0.411 inches (1.044 centimeters).

5. The wire support member of claim 1 , wherein the base edge further comprises a plurality of flanges extending from the base edge perpendicular to the first side.

6. The wire support member of claim 5 , wherein each of the plurality of flanges includes a clamp secured to the flange.

7. The wire support member of claim 1 further comprising an arm extending from the second edge, the arm including a flange extending perpendicularly from the arm, and the flange including a clamp secured to the flange.

8. A wire support assembly for an environmental control system, the wire support assembly comprising:
a wiring for the environmental control system comprising:
a first wire bundle extending from a pack control unit and branching into a second wire bundle and a third wire bundle;
the second wire bundle extending from the first wire bundle to an outboard module; and
the third wire bundle extending from the first wire bundle to an inboard module;

a first wire support member mounted to a first backbone support structure, the first wire support member supporting the first wire bundle, the second wire bundle, and the third wire bundle;
a second wire support member mounted to an outboard support structure of the outboard module, the second wire support member supporting the second wire bundle between the first wire support member and the outboard module; and
a third wire support member mounted to a first compressor casing of the inboard module, the third wire support member supporting the third wire bundle between the first wire support member and the inboard module, the third wire support member comprising:
a first side and a second side;
a first edge, a second edge, and a base edge, the first edge and the second edge forming a V-shaped apex opposite the base edge;
a first fastener opening having a center C and a diameter D 1 , a second fastener opening, and a third fastener opening, the first second and third fastener openings extending from the first side to the second side;
a length L 1 from the center C to the first edge and a length L 2 from the center C to the second edge; and
wherein a ratio of length L 1 to diameter D 1 is between 2.0 and 2.3.

9. The wire support assembly of claim 8 , wherein the third wire support member is mounted to the first compressor casing by fasteners extending through the first, second, and third fastener openings.

10. The wire support assembly of claim 8 , wherein length L 1 is between 0.860 inches (2.184 centimeters) and 0.920 inches (2.337 centimeters), and the diameter D 1 is between 0.401 inches (1.018 centimeters) and 0.411 inches (1.044 centimeters).

11. The wire support assembly of claim 8 , wherein a ratio of length L 2 to diameter D 1 is between 1.1 and 1.4.

12. The wire support member of claim 11 , wherein the length L 2 is between 0.470 (1.193 centimeters) inches and 0.530 inches (1.347 centimeters) and diameter D 1 is between 0.401 inches (1.018 centimeters) and 0.411 inches (1.044 centimeters).

13. The wire support assembly of claim 8 , wherein the base edge further comprises a plurality of flanges extending perpendicularly from the base edge.

14. The wire support assembly of claim 13 , wherein each of the plurality of flanges including a clamp mounted to the flange, the third wire bundle secured by the clamps.

15. The wire support assembly of claim 8 further comprising an arm extending from the second edge, the arm including a flange extending perpendicularly from the arm, and the flange including a clamp attached to the flange.
