Embodiment Construction

[0024] initial reference figure 1 , figure 1 Shown are the ends of an electrical connection element 10 having one or more conductors 12 for transmitting electrical signals, surrounded by a tubular protective structure 14, the ends of which are connected by coupling means 16 to connector 18.

[0025] The coupling device 16 includes a tubular connector 20 that surrounds the ends of the wires 12 that are electrically connected to the connector 18 .

[0026] In this example, the tubular connector 20 takes the form of a 90° elbow carrying at one end a nut 22 which is free to rotate and is threaded onto a corresponding part of the fitting 18 to secure the tubular connector 20 to connector 18.

[0027] An end of the tubular connector 20 away from the nut 22 has a fastener 24 to be fastened to an end of the tubular structure 14 . The tubular connector 20 is rigid and made of metal.

[0028] According to the invention, an insert 26 for protecting the wire 12 from wear is accommoda...

Abstract

An electrical connection element for a turbine engine, including conductors connected to a connector by a tubular coupling surrounding one end of the conductors, and an insert providing protection against wear of the conductors being mounted in the tubular coupling. The insert includes a substantially tubular central body containing the conductors and provided over at least a fraction of its length with a series of spacers bearing against an inside surface of the tubular coupling of the connection element so as to hold the central body at a distance from the inside surface.

Description

technical field [0001] The invention relates to an electrical connection element for a turbine engine, such as an aircraft turboprop or turbojet, and to an aircraft engine comprising such an element. Background technique [0002] Electrical connection elements consist of a set of electrical conductors that provide connections between various electrical devices, such as connections between sensors and electronically controlled engine regulation systems. [0003] The ends of the wires are connected to the connectors by coupling means comprising tubular connectors surrounding the ends of the wires. [0004] Couplings are used to accommodate the extra length of wire that allows the connector to be removed during maintenance to repair or replace the connector. [0005] In operation, the connection element is subjected to vibrations, whereby the wires rub against the inner surface of the tubular connector of the connection element and wear, which can cause electrical failure. An...
