Wiring harness design in CATIA V5 - 3D modeling Week 2 Challenge

AIM:

Download following connectors & Connector clip cad data from given link & define it as Electrical Connector using Electrical Part design Workbench. Define all the necessary properties to Connectors & Clip.

Introductions:

Connectors are the electro-mechanical devices used to form a continuous electronic signal to connect wire harnesses to a power source or circuit. On a basic level, connectors consist of male-ended plugs and female-ended jacks that can be joined together to relay an electronic signal. They are the familiar mating pair of polarized multi-pin connectors with wire leads. A male-ended plastic housing with release fits into a snap-mounted female-ended chassis mounting. The pair can be connected or disconnected easily and come in a variety of sizes, shapes, materials, quality, and dimensions—circular, header, pin, crimped, multitap—which are dependent on the

Procedure:

• THE CONNECTOR IS FIRST UPLOADED IN THE PART DESIGN WORKBENCH

• WE DEFINE THE POINTS FOR CONNECTOR CONNECTION AND BUNDLE CONNECTION.

• THE AXIS SYSTEMS ARE PLACED ON THE CONNECTOR CONNECTION AND CAVITY CONNECTION POINTS

• THE ORIENTATION OF THE AXIS SYSTEM IS NOT SPECIFIC, WE JUST NEED TO FOLLOW A SIMILAR ORIENTATION FOR ALL THE PARTS.

• HERE THE Y-AXIS IS IN THE DIRECTION OF THE CONNECTION, Z-AXIS ALONG WITH THE CLIP MOUNTING AND X-AXIS ALONG BOTTOM TO TOP.
  
  

• NOW WE DEFINE THIS PART AS AN ELECTRICAL ELEMENT/CONNECTOR, WITH THE NUMBER OF TERMINALS.

• CONNECTOR CONNECTION AND BUNDLE CONNECTION IS DEFINED IN THE ELECTRICAL PART DESIGN WORKBENCH.

THE SAME PROCESS WAS FOLLOWED FOR THE SECOND CONNECTOR. HERE WE NEED TO INCLUDE THE CONNECTOR-CAVITY CONNECTION POINT. THIS IS DONE TO FIX THE CLIP ON TO THE CONNECTOR.

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 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.

conclution

the connector connnection point and the

bunddle connection points of the model are defined
