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
- This application is based on and claims the priority under 35 U.S.C. §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.
- The invention provides additional protection for electrically insulated electrical conductors installed in a vehicle, particularly an aircraft.
- 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 interferences and/or other electrical effects also requires protection for the conductors.
- It is conventional to install electrically insulated conductors in individual hoses or tubular members. Such installation technology is, for example, used in all aircraft models manufactured by “Airbus”. In such wiring installations efforts are made to install or distribute the conductors with due regard to the route or connection for which the particular conductor is intended. For example, such routes or connections may run from a central control unit to a plurality of controlled units or from an electrical power source to a plurality of electrical power consumers in an aircraft. Separate wiring routes may be provided for communication purposes.
- 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. Such close installation requires a bundling of a plurality of individual protective hoses. Such bundling of a plurality of individual protective hoses is realized with cable binders or cable mounting bracket, whereby a plurality of such binders or brackets must be positioned along the length of a plurality of protective hoses for connecting these hoses to the aircraft structure. 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.
- In view of the foregoing it is the aim of the invention to achieve the following objects singly or in combination:
- to construct a protection or guard hose for protecting electrically insulated conductors in such a way that a defined separation of routes or electrical connections is assured when electrical signal conductors, electrical control conductors, and electrical power supply conductors are installed in such guard hose arrangements;
- 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;
- 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
- to interconnect a plurality of protection or guard hoses with spacers to save space; and
- to avoid an uncontrolled movement of individual insulated electrical conductors.
- The above objects have been achieved according to the invention by a guard hose arrangement for protecting insulated electrical conductors for installation in a vehicle such as an aircraft, wherein the guard or protection hose arrangement comprises a plurality of guard hoses, each of which has an inner diameter for receiving at least one, preferably a multitude of the insulated electrical conductors, and wherein each guard hose comprises an outwardly facing first contour along its length for connection to at least one spacer which has a second contour for cooperation with the outwardly facing first contour of the guard hose. This spacer is or spaces are positioned between two neighboring guard hoses of said plurality of guard hoses. One or many spacers may be positioned between two neighboring guard hoses and the number of guard hoses is not limited except for practical purposes, whereby these hoses are precisely spaced from one another along any desired length. At least two guard hoses are interconnected by at least one spacer.
- The plurality of guard hoses may be interconnected by their spacer or spacers while these hoses are manufactured to thereby produce an integral structure of at least two, preferably more, guard hoses spaced by a spacer or spacers. Preferably, the spacers are provided with cut-outs or through holes that may have different shapes to reduce the weight of these guard hose arrangements. However, manufacturing the guard hoses and the spacers separately for a subsequent interconnection is also possible, whereby the connection is, for example, performed by welding, adhesive bonding, and other suitable connections such as inserting the spacer or spacers in a groove of the guard hoses in a tongue and groove arrangement. Preferably, the spacers and the guard hoses are made of polytetrafluoroethylene (PTFE) in accordance with prescribed standards such as “NSA935805”.

The blank also has a width C which may correspond to the straight length A of the guard hoses shown in FIG. 3. According to the invention the blank of FIG. 7 is bent into an angle section shown in FIG. 7A. Preferably, the bending will take place along a centerline, or rather a preformed bending line BL so that the resulting legs of the angular section L1 and L2 will be approximately one half of the length B. These legs L1, L2 may be provided with cut-outs 9′ for reducing the weight of thespacers 5A and facilitating the mounting. The legs L1 and L2, however, also may have different lengths depending on the installation conditions to be satisfied. An angle α enclosed by the legs L1, L2 is preferably within the range of 45° to 90°. The bending line BL runs, for example, along a reduced thickness of the spacer blank of FIG. 7. - It is to be understood that
spacers 5A with an angular cross-section as shown in FIG. 7A may also be formed without any bending, for example by extrusion or molding techniques. In any event, the length of the legs L1 and L2, as well as the angle α will be selected with due regard to the installation requirements. This also applies to the position and number of theholes 9′. - FIG. 8 shows schematically a
spacer 5B having two side flanges SF1 and SF2 interconnected by a land L. The side flanges SF1 and SF2 enclose with the land L an angle β that is preferably 120°.
