Abstract

A disclosed harness assembly includes a base including a mounting surface and an opening that receives a mount end of a harness clip. A lockable clip is moveable between open and closed positions to secure one or more supply conduits or wire harnesses. The opening of the base includes a securement feature that corresponds with the mount end to hold the harness in a desired orientation relative to the base, to provide a fixed topographical routing.

Claims

1. A harness assembly comprising:

a base including a mounting surface and an opening;

a harness clamp including a mount end receivable within the opening and a lockable clip, the opening including a first securement feature and the mount end including a second securement feature engageable with the first securement feature for holding the harness in a fixed orientation relative to the base, wherein the harness clamp includes first splines extending longitudinally about an inner surface of the opening and second splines extending longitudinally along the mount end, the second splines engagable with the first splines for defining a rotational orientation of the harness relative to the base.

2. The harness assembly as recited in claim 1, wherein the clip comprises a fixed portion and a movable portion and a lever disposed on the movable portion for unlocking the clip.

3. The harness assembly as recited in claim 2, wherein both the fixed portion and the movable portion include interlocking teeth for holding the fixed portion to the movable portion when in the locked position.

4. The harness assembly as recited in claim 3, wherein the clip defines an enclosed area when in the locked position, wherein the interlocking teeth are engageable to vary the enclosed area.

5. The harness assembly as recited in claim 1, wherein the first splines within the opening extend transverse to the mounting surface.

6. The harness assembly as recited in claim 1, wherein the second splines extend longitudinally from the mount end toward the lockable clip.

7. A harness assembly comprising:

a base including a mounting surface and an opening;

a harness clamp including a mount end receivable within the opening and a lockable clip, the opening including a first securement feature and the mount end including a second securement feature engageable with the first securement feature for holding the harness in a fixed orientation relative to the base, wherein the opening includes a plurality of slots extending transverse to a centerline of the opening for a retainer extendable through corresponding slots for holding the harness to the base.

8. The harness assembly as recited in claim 7, wherein the retainer includes a spacing between fingers and the mount end of the harness includes a groove receivable within the spacing for securing the harness to the base.

9. The harness assembly as recited in claim 7, wherein the plurality of slots include corresponding slot pairs defining a height at which the harness extends from the base.

10. A harness assembly comprising:

a base including a mounting surface and an opening;

a harness clamp including a mount end receivable within the opening and a lockable clip, the opening including a first securement feature and the mount end including a second securement feature engageable with the first securement feature for holding the harness in a fixed orientation relative to the base, wherein the opening includes recesses and the mount end includes barbs engageable to the recess of the opening for securing the harness to the base and the recess contains a ramp feature and an opposing interlock feature to prevent counter-rotation.

11. The harness assembly as recited in claim 10, wherein the recesses are arranged in circumferentially spaced apart columns on an inner surface of the opening and the barbs are arranged in circumferentially spaced apart columns on an outer surface of the mount end.

12. The harness assembly as recited in claim 11, wherein barbs in adjacent columns including opposing angles such that rotation of the mount end within the opening moves the corresponding first barbs and second barbs from a released position to an engaged locking position.

13. The harness assembly as recited in claim 10, wherein the barbs are collapsible against a ramped recess through a cam action.

14. A fan section of a gas turbine engine including:

a case defining a bypass passage of the gas turbine engine;

a base secured to the case, the base including an opening;

at least one harness including a mount end receivable within the opening and a lockable clip defining an enclosed space in a locked position, the opening including a first securement feature and the mount end including a second securement feature engageable with the first securement feature for holding the harness in a fixed orientation relative to the base, wherein the opening includes a plurality of slots extending transverse to a centerline of the opening for a retainer extendable through corresponding slots for holding the harness to the base, the retainer including a spacing between fingers and the mount end of the harness includes a groove receivable within the spacing for securing the harness to the base; and

a supply conduit secured within the lockable clip.

15. The fan section as recited in claim 14, including first splines disposed about an inner surface of the opening and second splines on the mount end engageable with the first splines for defining a rotational orientation of the harness relative to the base.

16. The fan section as recited in claim 14, wherein the clip comprises a fixed portion, a movable portion, interlocking teeth that are engageable to vary an enclosed area and a lever disposed on the movable portion for unlocking the clip.

17. A method of securing a supply conduit to a surface comprising;

attaching a base to the surface;

inserting a mount end of a harness into an opening defined within the base;

inserting a portion of a supply conduit into a clip of the harness including setting a rotational position between the harness and the base by mating splines on the mount end with splines within the opening of the base; and

locking the clip around the supply conduit such that the supply conduit is held within an enclosed space defined by the clip.

18. The method as recited in claim 17, including setting a height of the clip relative to the base by engaging first securement features of the opening with second securement features defined on the mount end of the harness.
