Protection hose arrangement for conductors installed in an aircraft

Abstract

Insulated electrical conductors for installation in a vehicle, such as an aircraft, are further protected by a guard hose or tubular member. Two or more such guard hoses or tubular members are interconnected with each other by at least one spacer preferably, but not necessarily, integrally formed with the guard hoses or tubular member, whereby the separation of different types of electrical conductors and their installation in an aircraft are facilitated.

Description

PRIORITY CLAIM[0001] This application is based on and claims the priority under 35 U.S.C. .sctn.119 of German Patent Application 102 41 573.0-22, filed on Sep. 7, 2002, the entire disclosure of which is incorporated herein by reference.[0002] The invention provides additional protection for electrically insulated electrical conductors installed in a vehicle, particularly an aircraft.BACKGROUND INFORMATION[0003] The installation of insulated electrical conductors in a protection device such as a tubular or hose member provides one possibility, among several, for protecting the conductors against external mechanical adverse influences. Such adverse influences are, for example, caused by the transmission of vibrations which scour the electrical insulation thereby damaging the insulation, which in turn may lead to further problems such as moisture entering into the electrical conductors through the damaged insulation. The exposure of the electrical conductors to external electromagnetic...

AI Technical Summary

Benefits of technology

[0008] to reduce the effort and expense for repair work and for scheduled installation and monitoring work of the electrical wiring system in an aircraft or any other conveyance, such as a ship;

[0009] to facilitate the installation of a multitude of electrical conductors in an aircraft, thereby also improving the attachment of the electrical conductors to the aircraft frame structure; and

[0011] to avoid an uncontrolled movement of individual insulated electrical conductors.

[0018] FIG. 4 shows a spacer with a cut-out or hole to reduce weight and to facilitate the mounting;

Problems solved by technology

Such adverse influences are, for example, caused by the transmission of vibrations which scour the electrical insulation thereby damaging the insulation, which in turn may lead to further problems such as moisture entering into the electrical conductors through the damaged insulation.

Due to the multitude of connections or routes that must be established within an aircraft and due to the limited space available in an aircraft for such installations it becomes quite a challenge for the maintenance and repair crews to clearly distinguish individual conductors in the multitude of electrical conductors installed in individual protective tubular members or hoses.

A wrong connection may have disastrous effects.

Moreover, due to the limited space available for the wiring it becomes frequently necessary to position different conductor routes or connections quite closely to one another by installing different conductors and / or conductor bundles above one another and / or next to one another.

Accordingly, the maintenance personnel working inside the aircraft faces a quite confusing image of a multitude of wires which makes it difficult even for an experienced maintenance man to clearly sort out the various conductor routes.

This conventional situation makes it quite difficult to perform repair operations or to conduct scheduled maintenance and monitoring work on the electric installation or wiring in an aircraft.
