Alternate Cable Configurations Frank Johansen Raytheon Missile Systems

Biography Mechanical Engineer - Raytheon Missile Systems 10 years in electronics packaging and interconnect design Began using Pro/Cable in 1999 (version 17?) Currently transitioning from Pro/Diagram to RSD

When would you need different configurations of the same cable part? Redundant systems (using Flexibility) Same cable assembly used more than once Simplified versions of the same cable (Using sub-harnesses and Family Tables) One configuration with instrumentation lines Second configuration without instrumentation 3 3

Redundant Systems Example: Safety critical applications which require redundancy. Components are often mirrored, or stacked. Component A Component A Component B

Creating a Flexible Cable Assembly First Connector assembled by Default

Creating a Flexible Cable Assembly Assemble the Cable.asm into the Upper_Level.asm, using connector placement constraints of the longer of the two cables. Component B

Creating a Flexible Cable Assembly With the Upper_Level.asm active, place a temporary connector at component A interface. Component A

Creating a Flexible Cable Assembly With cable.asm active, create coordinate system to place connector2.

Creating a Flexible Cable Assembly Assemble connector2 into cable.asm by coordinate system.

Creating a Flexible Cable Assembly Set up Flexibility by pre-defining the X, Y and Z offsets of Connector_2 coordinate system

Creating a Flexible Cable Assembly Route harness for the longer of the two cables Entry Port Offset by coordinate system to create first locations away from connectors.

Creating a Flexible Cable Assembly Bundle from Point A to Point B Fix Length of bundled segment Round up to common lengths Point A Point B

Creating a Flexible Cable Assembly Assemble second cable.asm into Upper_level.asm

Creating a Flexible Cable Assembly Place temporary connector at second location Create coordinate system (connector_2b) Use for dx, dy, dz measurements Retain in cable.asm for reference

Creating a Flexible Cable Assembly Redefine the second cable.asm and change the values for the varied items within Flexibility to define the correct connector placement

Creating a Flexible Cable Assembly Cable assemblies are identical, with the exception of routing path Same connector parts Same cable part Same length Will show up in a smart parts list as the same part with a quantity of 2

Creating Cable Family Tables Another case in which you may need different configurations of the same cable is having a simplified version of an existing cable. This is more along the lines of a -1 and -2 configuration of a cable assembly Picture Here

Creating Cable Family Tables In Cabling Application Start with Routed -1 cable assembly configuration Identify cable id’s of wires wanting to exclude If using Pre-WF4, rename features to coincide with wire numbers Picture Here

Creating Cable Family Tables Create Cable part family table Picture Here

Creating Cable Family Tables Add feature columns to include each wire id that may be removed for the -2 configuration Picture Here

Creating Cable Family Tables Assign Y/N values accordingly Picture Here

Creating Cable Family Tables In Standard Application Create family table Include components to be omitted Include cable.prt component Picture Here

Creating Cable Family Tables Replace using Family member Select appropriate cable.prt instance Picture Here
