Problems solved by technology

For the operator, the duration of the maintenance operation is further extended by the need to remove the cable to be repaired from each clamp, and when blocked by other cables in the harness and holding said cable to be repaired very tightly, this Operation can be tiring for the operator

Embodiment Construction

[0039] Figure 1 shows an assembly 1 comprising:

[0040] - a wire harness 2 wound as a coil, said wire harness comprising a plurality of electric wires 3; and

[0041] - An extra long control coil 4 to which said cable 3 is fixed.

[0042] The harness 2 , here an electrical harness 2 , comprising several cables 3 , here six, held together by cable grommets 5 , has roughly the shape of a sheath. The wire bundles 2 wound as a coil arrangement, here the cables 3 forming the wire bundle 2 , are substantially parallel to one another and are not twisted together so that no zero phase-sequence impedance arises.

[0043] Before installing the harness 2 on the part of the aircraft, the harness 2 is assembled by an operator who feeds several cables 3 independently of each other and assembles them using cable grommets 5 .

[0044] The independent feeding of the cables 3 makes the bundle 2 irregular, ie each end of a cable 3 is not entirely in the same plane P as the ends of the other c...

Abstract

The invention relates to an assembly (1) comprising: - a harness (2) which comprises a plurality of electrical cables (3), and - a coil (4) that has a body on which said cables (3) are fixed, characterized in that the coil (4) comprises arms mounted on said body, at a first end, each arm having a second end on which one of said cables (3) is fixed, the second end being movable with respect to thebody, independently of the second ends of the other arms, between a position for maximum absorption of overlength of cable (3), in which the second end is remote from the body, and a position for maximum creation of overlength of cable (3), in which the second end is closer to the body.

Description

technical field [0001] The invention relates to a coil for handling cable overlengths in a bundle of wires wound as a coil. Background technique [0002] For ease of manufacture, the spacecraft is built in sections joined end-to-end, which are then transported to the assembly site. [0003] Each part includes structural parts, skins, and circuits for fluidics and energy transfer, such as electrical circuits. The circuit consists of multiple bundles of wires, each with several cables, where two sections of the bundle are joined together by connectors. [0004] Each cable in the wire harness has an active sector as well as an extra-long sector, so that on the one hand a repair length for repairing the cable can be created if the cable is damaged, and on the other hand a teardrop-shaped length can be formed such that A U-shaped area can be created on the cable, along which the condensate flow does not reach the end of the cable and thus the harness connector. [0005] In ord...
