POKA-YOKE FOR A SET OF HYDRAULIC FITTINGS

摘要

A hydraulic manifold assembly having a block including a plurality of fluid ports provided on a common surface of the block, and a set of hydraulic fittings. Each fitting is assigned to a prescribed one of the ports. Each fitting includes a hollow bolt insertable into the prescribed fluid port, and a banjo block having a first aperture for receiving the hollow bolt and a second aperture intersecting the first aperture. The second aperture provides an external fluid port for fluidly coupling a remote device. The plurality of banjo blocks includes at least one adjacent pair of banjo blocks that are unique from each other and have exterior shapes complementary to each other to control the relative orientation therebetween when coupled to the prescribed fluid ports. The exterior shapes of the adjacent banjo blocks cooperate to prevent misassembly.
