There are several specialized tools (that I have no experience with) for doing wire harnesses including SolidWorks Electrical, MentorGraphics VeSys, and Zuken E3. I usually create parts that looks like to use as pins and sockets, and then draw a wire to connect them. My preferred approach is to use an ECAD program such as Altium or KiCad and draw the wiring diagram in a schematic window. There are several software packages that can be used for drawing harnesses. Another critical thing is having the data and revision on the diagram. You will also notice that the connector, pins, sockets, and wires are described and have part numbers. In the example image above you can see the connector box in the middle that shows which side are pins and which side has sockets (the sockets are on the powered side). Harness: Which wire is connected to which pin, shields So what should go on the wiring diagram? The simple answer is everything that you will need to identify what each conductor in the cable is and how to recreate the wire harness.Ī more detailed answer is that it should have the following:Ĭable: Number of Conductors, Gauge, Shielded vs non-shielded, LengthĬonnectors: Connector part number, pin/socket part numbers While I am only talking about the diagram there are a lot of standards about how to design and build a harness. Use the Compile Errors dialog to cross probe to the offending objects (Sheet Entries, Ports, Harness Connectors or Harness Entries) within the Signal Harness. A wiring diagram is not only needed for wiring the robot but is also a valuable resource to have if you ever need to modify the electrical systems in the robot or when you are debugging a problem. HarnessType1 and HarnessType2 are the multiple Harness Types specified across the Signal Harness. So it is time to think about wiring up your robot, one of the key steps before you begin is to develop a wiring diagram. ( See full size wire harness diagram here)
