Description
Technical Field
The utility model belongs to the technical field of design of an electrical interconnection system of an airplane, and particularly relates to a cross-rotation axis bundle laying tool.
Background
The wiring harness laying across the rotating shaft is a difficult point for wiring of an electrical interconnection system. When the device is mounted on a movable structure such as a hatch door that moves about a pivot axis, the device may rotate about the pivot axis with the movable structure, and this rotational movement may damage the interconnecting cables of the device. Take the electronic device installed on the cabin door as an example: the electronic equipment is arranged in the cabin door area, the interconnection harness of the electronic equipment crosses over the rotating shaft of the cabin door, and the power supply and other equipment which are in signal cross-linking with the power supply and other equipment extend out of the cabin door area. When the hatch door moves, the wire harness across the rotating shaft can be stretched or compressed along with the hatch door.
In order to ensure that the wire harness crossing the rotating shaft is not broken, the existing conventional solution is as follows: the length of the wire harness across the spindle is specified in terms of the maximum tensile limit of the spindle movement. The limitations of this approach are: when the rotating shaft moves to the maximum stretching limit position, the wire harness is not broken due to insufficient length, but when the rotating shaft moves to the minimum stretching limit position, the wire harness is easy to loose and wind around other surrounding parts due to too long length. If the wiring harness wound on the surrounding parts cannot be timely disassembled, the wiring harness is broken when the rotating shaft moves to the maximum stretching limit position next time.
Therefore, according to the conventional cross-rotating-axis harness laying method, when the length difference of the harness required by the maximum stretching limit position and the minimum limit position is large and the movement frequency of the rotating shaft is high, the harness crossing the rotating shaft has a large damage risk.
