Abstract: A gas turbine engine installation is provided that has a flexible printed circuit board (FPCB) harness to transfer electrical signals, including electrical power, around a gas turbine engine. The FPCB harness is held to the gas turbine engine installation using clips. The clips have a jaw that has two sets of opposing teeth extending from a base, and a mouth through which the FPCB harness is inserted. The teeth point in a direction that has a component from the mouth to the teeth. This means that the force required to insert the FPCB harness into the clip is lower than the force required to pull the FPCB harness out of the clip in the opposite direction. This means that the FPCB harness can be secured in place while aiding ease of assembly.

Abstract: 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.

Abstract: 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 clips that have at least two jaws. Each jaw has two sets of opposing teeth that do not intermesh, and cannot intermesh when pushed together. This allows more than one FPCB harness to be held by one clip without the risk of damaging the FPCB harnesses. Preventing the teeth from intermeshing also allows subsequent FPCB harnesses to be inserted into the clip without undue difficulty even after a first FPCB harness has already been inserted.
