Wire harness block clamp

A gas turbine engine comprising:

• a compressor, a turbine and a combustor;
• a plurality of wire harnesses each having an outer periphery, and a protective outer coating around at least one electrical wire;
• a clamp including at least two clamp halves to form a cylindrical space for receiving and supporting each of the plurality of wire harnesses, the clamp having grommets associated with each of the at least two clamp halves, the grommets being formed of a non-metallic material, the at least two clamp halves being secured together, and being secured to a static surface, and there being an alignment feature to align the at least two clamp halves relative to each other;
• and wherein the alignment feature includes a tongue on a first of the at least two clamp halves and a groove on a second of the at least two clamp halves, with the tongue received in the groove;
• wherein each of the at least two clamp halves have a stop, to prevent overtightening when the at least two clamp halves are secured together;
• wherein the at least two clamp halves are secured together by a bolt;
• and wherein the grommets have shoulders extending in a direction from each of the grommets toward the other of the grommets and having an opening with the bolt passing through said shoulder, and the shoulders on the grommets also being formed of a non-metallic material, and at least two of said clamps are positioned adjacent to each other, and being secured to the static surface by a single fastener, with each of the grommets of the at least two clamp halves on each of the at least two clamps having the shoulders extending towards an opposed one of said at least two clamps, such that there are four of said shoulders with the openings all receiving the bolt.
