Device enabling cable to be fixed on aircraft structure, dilatation method for device and aircraft body

Abstract

The invention relates to a device enabling a cable to be fixed on an aircraft structure. The elemental form of the device is a first wire groove element which forms a basic wire groove element, the basic wire groove element comprises a device which is connected to the aircraft structure, and the device is located on the bottom side of the basic wire groove element, is allocated to be the mode of receiving at least one cable distributed along the aircraft structure and provides electric continuity on the whole aircraft body length. The device is characterized in that the basic wire groove element comprises a first connecting device which can be combined with corresponding connecting device of a second wire groove element, and the second wire groove element forms a side dilatation wire groove element. The invention further relates to a method for expanding and containing capability of the device enabling the cable to be fixed on the aircraft structure. The device enabling the cable to be fixed on the aircraft structure can simply and rapidly increase capability of a wiring fixed by the fixed device under needed situations. The invention further provides an aircraft body.

Description

Technical field [0001] The technical field of the present invention relates to wiring, and more specifically, to wiring and fixing in airplanes. Background technique [0002] Generally, the structure of an airplane is realized by a series of circular frames, which are supported by longitudinal frame members and are evenly arranged along the fuselage. The frames are fixed with bars called longitudinal beams. The outer shell of the aircraft is attached to the aforementioned frame network and stringers. [0003] Whether it is an ordinary airplane or a helicopter, the wing structure is usually made of metal, which has certain advantages. In particular, the conductive properties of metals enable it to achieve the following functions: [0004] -Generate a power grid for the current returned from the equipment of the aircraft. The components of these equipment are electrically connected to the electrical wires carrying the current, not to the aircraft structure. Therefore, there is no ne...

Problems solved by technology

The first disadvantage of this configuration is that the inevitability of the expansion is not obvious, and in fact it doubles the weight of the trunking element, and most importantly, the opening of the trunking element is oriented towards the Aircraft walls, whereby the cables are not restrained in the trunking elements, thus not solving the problem of preventing short circuits on aircraft made of composite materials
