Project 2
Aim: To route the wiring harness on the given tailgate assembly and prepare the flatten view drawing in CATIA V5.
Given: Car Tailgate Assembly
DESIGN CRITERIA AND PACKAGING ASSUMPTIONS:
- Wiring harness routing shall provide ease in manufacturing, accessibility, easy removal, and easy maintenance of attached equipment and wiring harness.
- Routing through small structural holes and openings shall be avoided, minimize chaffing and handling of the wiring harness during installation.
- Avoid the harness routing and clipping in the Blind zone of the Operator during harness assembly or in service.
- Routing shall offer protection against possible damage through common misuses such as being handhold and temporary support for test equipment.
- Provide additional slack to the harness according to the surroundings and harness bending requirements. Ensure the routing meets the clearance requirements with different surrounding parts.
- Avoid routing over the bolts, near to the bolted joints. It may damage the harness or puncture the harness. Keep harness away from panel mounting screws.
- Avoid harness routing near sharp edges, if not possible provide protection to the harness. The maximum distance between two clips on a straight branch is 200mm.
- Provide Clips and clamps if the harness is going to bend at multiple locations. The use of too many sheet-metal brackets should be avoided.
- The branch length should be more than 50 mm.
- Min distance between clip and branching point to be 25 mm. Min distance between two branch breakouts should be 50 mm.
Routing the Wiring Harness:
- First, we have to consider the components we need for the Here we are only considering the taillights.
