Gas turbine engine installation including a flexible printed circuit board harness for transferring electrical signals around the gas turbine engine installation

摘要

A gas turbine engine installation is provided that has a plurality of flexible printed circuit board (FPCB) harnesses to transfer electrical signals, including electrical power, around a gas turbine engine. The plurality of FPCB harnesses is held to the gas turbine engine installation using generally U-shaped clips that have a base from which first and second sidewalls extend. The FPCB harness is held between the tips of base-teeth extending from the base, and side-teeth extending from the first and second sidewalls. In this way, the FPCB harness can be held securely in position by the clip.

1. A gas turbine engine installation comprising:
a flexible printed circuit board harness arranged to transfer electrical signals around the gas turbine engine installation, the flexible printed circuit board harness being a thin, elongate member having upper and lower parallel major surfaces defined by a length (x) and a width (y), the flexible printed circuit harness further having a thickness (z) normal to the parallel major surfaces, the width (y) being longer than the thickness (z); and at least one clip holding the flexible printed circuit board harness, each clip comprising a generally U-shaped member defined by a base having a first end and a second end, the base spanning the width (y) between the first end and the second end, each clip further comprising a first sidewall extending from the first end and a second sidewall extending from the second end, and an opening opposite the base and between the first and second sidewalls for the insertion of the flexible printed circuit board harness wherein: the first sidewall has a first side-tooth extending therefrom, and the second sidewall has a second side-tooth extending therefrom; the base has a first set of base-teeth and a second set of base-teeth arranged such that a first portion of the flexible printed circuit board harness is gripped between tips of the first set of base-teeth and a tip of the first side-tooth, and a second portion of the flexible printed circuit board harness is gripped between tips of the second set of base-teeth and a tip of the second side-tooth; and the width (y) of the flexible printed circuit board harness is contained entirely between the first and second sidewalls.
