Project 1
Aim:-
To Route the Wiring harness on Given Engine and Prepare flatten view drawing in CATIA V5. Apply Protection coverings as required.
Given
Engine
DESIGN CRITERIA AND PACKAGING ASSUMPTIONS:
- Provide clips/clamps as per requirement.
- Make sure that there is no any fauling case while designing the wire harness. Additional clips/clamps may be used to avoid fauling case.
- Give additional slack if needed. 5-10% slack is sufficient.
- Avoid routing over bolt and bolted joints to avoid harness puncture.
- Avoid routing on sharp edges or else provide protection over the harness.
- Follow the clearance distance and keep away the harness from heat generation components.
- Protection should be provided as needed according to surrounding temperature.
- Avoid direct support for harness on fuel lines routed in the engine.
- Use plastic guiding channels if needed.
- Branch length should be greater than 50mm.
- Minimum distance between two branch points should be at least 50mm.
- Minimum distance between clip and branch point should be at least 25mm.
- Avoid too many sheet metal brackets on the engine. Try to use available threaded bosses on the engine or demand for it.
- The wiring harness should be easy to assemble and easy to access.
- While using dummy connectors, ensure that whatever positions you are defining that are practical. Bundle diameters and another placements can be defined properly for the wire harness routing.
- If the packaging area is too tight and there are many packaging constraints then we can think of creating harness channel which can be used to route and protect the wire harness effectively.
Defining all the Mechanical components into electrical and support components:
Connectors:-
C-1563689-1
C-776438-4
C-1924487-2
P-CLAMP
Fir tree clip
Guiding Channel
Routing the wiring harness:
A sheet metal bracket was created for the interconnection connector to be placed near the engine.
