Abstract

A device connects a wire harness to a structure. A fixation portion of the device is secured to the structure. A spacing portion is connected to the fixation portion and to a connector portion. A retaining clip on the connector portion deforms when a wire harness connector component moves axially toward the fixation portion. The clip opposes an abutment edge against the component into engagement position when the component is past the clip to prevent it from moving back onto the clip. An abutment surface contacts another portion of the component in engagement position to prevent further axial movement of the component toward the fixation portion. The component is held captive between the edge and the abutment surface. Also provided are a cable support for connecting the wire harness to the device, a method for connecting and disconnecting the wire harness to a structure with the device, and an aircraft.

First claim

The invention claimed is:

1. A device for connecting a wire harness to a structure, comprising:
a fixation portion adapted to be secured to the structure;
a spacing portion connected at a first end to the fixation portion;
a connector portion connected to a second end of the spacing portion and spaced apart from the fixation portion, the connector portion comprising a retaining clip adapted to resiliently deform when a wire harness connector component moves axially thereon toward the fixation portion and adapted to oppose at least one abutment edge against a first portion of the connector component into an engagement position when the connector component is past the retaining clip to prevent the connector component from moving back onto the retaining clip, and at least one abutment surface adapted to contact a second portion of the connector component in the engagement position to prevent further axial movement of the connector component toward the fixation portion, whereby the connector component is held captive between the at least one edge and the at least one abutment surface; and
indexation formations between the at least one abutment edge and the at least one abutment surface, the indexation formations adapted to be indexingly engaged with complementary indexation formations on the wire harness connector component, whereby the wire harness connector component is blocked in orientation relative to the device.

2. The device according to claim 1 , further comprising an elastomeric absorber on the connector portion between the at least one abutment edge and the at least one abutment surface, the elastomeric absorber adapted to contact the wire harness connector component in the engagement position.

3. The device according to claim 1 , wherein the indexation formations are indexation blocks each having a stair geometry.

4. The device according to claim 1 , wherein the at least one abutment surface is part of a flange on the connector portion.

5. The device according to claim 4 , further comprising at least one cut-out in the flange, the at least one cut-out being in alignment with a respective fastener of the fixation portion.

6. The device according to claim 1 , wherein the fixation portion has a base plate having an undersurface adapted to be laid onto the structure when the device is secured to the structure.

7. The device according to claim 1 , wherein the retaining clip has a skirt geometry, with a flared portion of the retaining clip oriented toward the fixation portion.

8. The device according to claim 7 , wherein the flared portion comprises at least two resilient tabs, with each of the resilient tabs comprising one of the abutment edges.

9. The device according to claim 6 , wherein the spacing portion has an elongated body between the fixation portion and the connector portion.

10. The device according to claim 9 , wherein the elongated body of the spacing portion has one of a longitudinal axis normal to the undersurface of the base plate and a longitudinal axis parallel to the undersurface of the base plate.

11. A system for connecting a wire harness to a structure, comprising:
a wire harness connector component comprising:
a through bore;
a first cable interface that is laterally offset in relation to the through bore; and
a second cable interface that is laterally offset in relation to the through bore; and

a standoff device, comprising:
a fixation portion adapted to be secured to the structure; and
a spacing portion connected at a first end to the fixation portion; and
a connector portion connected to a second end of the spacing portion and spaced apart from the fixation portion, the connector portion comprising:
a retaining clip adapted to resiliently deform when the wire harness connector component moves axially thereon toward the fixation portion and adapted to oppose at least one abutment edge against a first portion of the connector component into an engagement position when the connector component is past the retaining clip to prevent the connector component from moving back onto the retaining clip; and
at least one abutment surface adapted to contact a second portion of the connector component in the engagement position to prevent further axial movement of the connector component toward the fixation portion, whereby the connector component is held captive between the at least one edge and the at least one abutment surface.

12. The system according to claim 11 , wherein the first and second cable interfaces are disposed at laterally opposing positions with respect to the through bore and define a double cable support.

13. The system according to claim 11 , wherein the first and second cable interfaces each comprise:
a support surface with a trough shape; and
a lug transversely positioned with respect to the support surface, the lug defining a passage thereunder.

14. The system according to claim 13 , further comprising:
an opening in the cable interface, beneath the lug, providing access to a fastener from a position beneath the cable interface.
