INTRODUCTION TO WIRE HARNESS

Terminologies & 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 logical connectivity diagram representse 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 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 schematic is detail design of Logical schematics which describes the pin to pin connectivity, Properties, Fusing distribution, Grounding distribution, Interconnects, Wire properties, Circuit properties, Specification of components etc. This is the end result of Electrical core design of system and used as an primary input for harness development.

Wiring harness Routing:

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

Wiring harness Packaging:

Wiring harness packaging deals with Fixing/Mounting strategy of wiring harness routing to ensure the safe,Reliable & Durability of wiring harness by applying set of design rules & industry best practices.

Connector Definition

Following Parameters are required to defined for any connector -

Geometry Parameters - Points & Co-ordinate system (Axis)

Connector connection points - This point is used for the connection of one connector to another connector.

Harness bundle entry point - This point defines where the harness bundle segment point will end when routed to the electrical connector.

Cavity connection point (Optional) - This point is used to define the connection of a connector to a connector clip. This only applies to connectors which have the mounting feature for a connector clip.

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

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

3. 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.

Elctric Assembly Design

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