Wiring harness design in CATIA V5 - 3D modeling Week 5 & 6 Challenge

Solution:

• All the Connectors are downloaded from Google Drive link by skill lync
• We have downloaded all the igs zip files
• All the files are extracted

• Open the CATIA software and convert the files to CAT parts

• All the Connectors are electricaly defined with the below steps

• Part body is opened and points are created for bundle entry
• Mating points are also created along with the axis definition
• we then switch to electrical part design
• We define the parts as connectors
• We define the point and budle entry point
• Connection connector point is also made.
• This is done for all the ten connectors.
• Hence it is electricaly defined.
• We then create a catalog for this challenge and all the connectors.
• Here are few photos of the steps.

• New product is opened and it is named as Harness A and Harness B
• It is defined as geomentric bundle. Note the symbol has changed now.

  

• We add all the connectors here

   

• The connectors are aligned as per the photo given.
• We use various commands to rotate and move the connectors

• Multi branchable is added to the geomentrical bundle
• Connectors are routed with the branch bundle by clicking the connectors
• To add sub branches Branch point is created on the main line.
• Then branches are routed to the connectors as per the question
• Tangency are changed to give a good curvature to the harness bundle

Problems and solutions in bundle routing warning:

• Have tangency so that the wire travels minimum distance
• So here we can change the reverse tangency to correct this 

• This also a miss align of bundle that is shown in red line
• We can change the tangency of second connector to correct this issue

• We will get this kind of red line mentioning as error.
• For this we have multiple solution.

• we can increase the slack
• we can reverse the tangency
• we can move the connector location

• But here we have reversed the tangency to get the problem resolve

• Sometimes given high slack also makes problem
• So we kept minimal or 0 slack

• Keep the branch points bit away so that the branch has a good curvature

• We will get this kind of red line mentioning as error.
• For this we have multiple solution.

• we can increase the slack
• we can reverse the tangency
• we can move the connector location

• But here we have reversed the tangency to get the problem resolve

• Keep a good minimal cure of bundle to reach the connector

Assembly:

• New product is created and Harness A and Haness B is added
• Both the harness are joined with link

Annotations:

• Annotations are given to all the connectors
• Part assembly design is used here
• plane is created and names are added

Bundle continuity:

• Bundle continuty is checked by clicking search and electrical and bundle segment and fully connected
• here are the results

Assembly is saved as igs format in the attachement
