Dear Team,

Please find the attached Cat part file and Images for your reference.

Wiring Harness - Engine

An Engine Wiring Harness is constricted Wires , Cables, terminals , and Connectors Controlling a vehicle's electrical system. It relays electrical Power and Control Information to Components Such as batteries, alternators , fuel injectors, fuses , audio systems, blower motors , fuel Injectors, and Computers. Wire harness companies customize it for every location, application, and design it interconnects. Also Known as Cable harness, it is more than just a collection of multiple of wires Put together.

It manages the key functions around the engine Including Engine controller, oil controller gate, transmission plug housing, air Pipe Sensors, Pressure Sensors, and Water temperature Sensors.

Wiring Harness creation:

* Download the Engine Cad Data and Required Connectors CAD data from the given Source.

• Add all the electrically defined components to the geometrical bundle.place the components at proper location for routing the harness
• Then switch into the electrical harness assembly workbench and Geometrical bundle product file should be electrically defined using the Define Geometrical bundle option .

Harness routing and packaging

• The available connectors are added into the geometrical bundle and properly positioned onto the fuel injectors, camshaft sensors, vehicle speed sensor, neutral position sensor and engine coolant sensor.manipulation tool is used to place the connectors.

• Here we have one interconnection connector to connect engine harness system to vehicle harness system.so it required additional parking provision.Existing bolt on the engine is used to mount the sheet metal bracket. The bracket should be provided with a suitable locking feature in clockwise direction.first mount the clip on the sheet metal bracket .Then the interconnection connector is electrically connected with the mounting clip by using connect electrical devices command in the electrical assembly design workbench.

• design criteria followed to route the wiring harness

  • Wiring harness routed by considering the factors ease in manufacturing, accessibility, easy removal and easy maintenance of attached equipments and routing harness.
  • Wiring harness should be routed in such a way that it is easy to assemble on a vehicle.
  • Wiring harness should be kept away from sharp environments like sheet metal brackets, panel edges, corners etc.
  • Avoid harness routing and clipping in blind zone of operator during harness during installation.
  • Ensure that routing meets the clearance requirements with the different surrounding parts.
  • Routing shall provide enough slack for each branch to avoid additional stress on wire and terminal crimping joints but ensure that extra slack does not cause wiring harness foul with surrounding parts and impact desired clearance requirements.
  • Enough clamps should be provided to ensure the positive clearance with surrounding and safety of wiring harness.
  • Use of plastic guided channels are recommended to meet the clearances in critical areas if it is difficult to achieve by use of clamps.
  • Branch length should be minimum 50mm.
  • Minimum distance between clip and nearest branching point should be 25mm.
  • Minimum distance between two breakouts should be 50mm.
  • Limit the no. of branches from single branch point upto 4.
  • Ensure that harness protection is provided according to surrounding temperature, manufacturabilty and expected reliability.
  • The min. bend radius is to be 1.4.

  • WIRING HARNESS FLATTENING
    

  Create a new product file for flatten the wiring harness and save as in the same folder where the wiring harness is saved. Then switch to Electrical harness flattening workbench and select harness flattening parameters and define harness flattening parameters. Before creating flatten view, Make sure that selecting 'Double line' for bundle segment and 'Double' line for protective covering.

• 
  

• drawing of the flattened wiring harness

  open a new drawing file and Select front view command, then go to the flattened harness window and select a suitable face to create drafting of the harness.

  to make the bundle segments visible right click on the drawing sheet and go to properties, in the view tab, highlight '3D wireframe' and 'is always visible' in the dress up settings.
