THEORY:-
INTRODUCTION
Terms using in wiring harness are given below:-
- Electrical distribution systems (EDS)
Electrical distribution system basically deals with physical and logical architecture, systematic development, power distribution, wiring harness design, wiring harness components design of given electrical system.
- E and E Architecture:-
It is high logical connectivity diagram represents the number of systems, sub-systems and logical connectivity between them. It is also extended to show the CAN network between different electronic controllers.
- Logical schematics:-
Logical schematic is detailed of E&E architecture which is extended to show the logical connectivity between different components and controllers of the given systems or sub-systems.
- Electrical Schematics:-
Electrical schematic is detailed of logical schematics which is describes the pin-to-pin connectivity, properties, fusing distribution, interconnect, ground distribution, wire properties, circuit properties, specification of components etc. This is the end result of electrical core design of system and use as a primary input of harness development.
- Wiring Harness topology:-
Wiring harness topology is strategy to divide or split the harness between different pieces to achieve the best manufacturability, serviceability and cost effective design.
- Wiring Harness Routing:-
Wiring harness routing deals with desired path of wiring harness in given vehicle environment by applying set of design rules and industries best practices.
- Wiring Harness Packing:-
Wiring harness packing deals with fixing and mounting strategy of wiring harness routing to ensure the safe, reliable and durability of wiring harness by set of design rules and industries best practices.

CONNECTOR DEFINATIONS IN CATIA V5
- Deutsch DT06 – 08SA
Connector connection point:
Create midpoint on the contact face which will be normal to wire bundle insertion.
Create Axis System with respect to the point which we have created and defining the axis direction as shown below
Bundle connection point:
Switch to 'Electric Part Design'
Define the part as connector in Catia, give no. of termination as 8 because we have 8 entry points for wire.
Define Bundle connection point
Define connector connection point
2.Tyco 174357-2 :
- Create midpoint
- create Connector connection point
- create Connector connection axis system
- create cavity connection point
- create cavity connection axis system
- Switch to Electric part design and define part as connector
- Define Connector connection point and cavity connection point
- Tyco 85229-1 :
- Create midpoint
- create cavity connection point
- create cavity connection axis system and orientation should be same as in connector
- Switch to Electric part design and define part as Mounting Equipment
- Define cavity connection point
Electric Assembly Design
- Import Connector and cavity / mounting clip.
- Select Define Electric connection
- select cavity and then connector.
CONCLUSION:-
Thus, all parameters of the given components is done.
