• INTRODUCTION TO WIRE HARNESS

Teminologies & Definitions

• Electrical Distribution System (EDS)

Electrical Distribution System basically deals with physical & Logical architecture, Schematic Development, Power Distribution, Wiring Harness Design, Wiring Harness Component Design of given electrical system.

• E&E Architecture

it is high level electrical connectivity diagram represents the number of systems, sub systems and logical connectivity between them. it is also extended to show the CAN network between electronic controllers.

• Logical Schematics

Logical schematic is the detailed design of E&E Architecture which is extended to show the logical connectivity between different components & controls of given system, Sub System.

• Electrical Schematics

Electrical schematics is the detailed design of logical schematics which describes the pin to pin connectivity, properties, fusing distribution, grounding distribution, interconnects, wire propertie, circuit properties, specififcation of components et. this is the end result of Electrical core design of system and used as an primary input for harness design.

• Wiring Harness Topology -

it is a strategy to devide or split the harness between different pieces to achieve the best manufacturability, serviceability & Cost effective design.

• Wiring Harness Routing

wiring harness routing deals with desired path of wiring harness into given vehicle environment by applying set of design rules and industry best practices.

• Wiring harness packaging

it deals with mounting/ fixing strategy of wiring harness routing to ensure the safe, reliable & durability of wiring harness by applying set of design rules & industry best pactices.

• FLOW CHART OF DEFINING ELECTRIC PARAMETER

• CONNECTOR DEFINATIONS IN CATIA V5

1. Deutsch DT06 – 08SA

Connector connection point:

Create midpoint on the contact face which will be normal to wire bunddle insertion.

Craete 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 C-2-174357-2 :

• 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

3. Tyco C-0085229-1 :

• 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

Elctrical Assembly Design

• Import Connector and cavity / mounting clip.
• Select Defing Eelectric connection
• select cavity and then connector.
