Wire routing of engine

Aim:

             Electrically defined the given connecters with the help of geometry, routing between connecters and apply corrugated tubes on the wires by the electrical wiring harness workbench. Then flattening the assembly and create the drawing by CATIA V5.

Introduction:

    Wiring harness:

               Systematic bound of electric wires and electric parts This process is doing in CAD for assembly and production. E.g.: wire, connecters, back shell etc

     Connecters:

                        It is connecting electrically one function with another or connect the wires.

                              

   Wire Buddle:

         A compact group of electrical wires held together with special warping device. It connects the electricity one to another component. Inside copper and cotted with plastics like PVC, PP. 

              

   Corrugated tubes:

                   It is bellows shapes and flexible. It is using to product the wiring harness and give aesthetic looks. It also made by plastics.

                

    P clamps:

         It is a type of clamp which is made from metal or plastics or both. It mechanically fastens electrical cables, hydraulic wires or tubes along route.

                     

    Clips:

         It is a type of clips which is made from plastics. It is used to fixed the wires and tubes along route. Wires are fixed by cable ties or snap fit in clips.

                        

   Engine:

          It converts the one form of energy to another form of energy. In the engine different type of fuel injector, senser and other electrical parts are using. So, this all part are connected by wires with external input.

                     

Tools:

     For electrically define some create some geometries and electrical part design tools.

 Mechanical part work bench:

    Point:

          It indicates one location. This tool is used to create between two points in the centre of face.

    Axis system:

           It is fixed on a point and give X, Y, Z direction and plane in the location which is used to define and assemble the electrical parts.

 Electrical part work bench:

    Define connecters:

             This option is used to define the connecter with buddle entry points. After this process CATIA will take the part as connecter.

    Define mounding equipment:

              This option is used to define as mounding equipment. After this process it take as mounding equipment.

    Define connecter connection point:

                This option is used to define the connecter connection point with the help representation, contact, coincident and orientation which are given by point, surface and axis system.

    Define bundle connection point:

                This option is used to define the bundle entry point of connecter with the help representation, contact, coincident and orientation which are given by point, surface and axis system.

   Define cavity connection point:

                This option is used to define the cavity connection point of connecter with the help representation, contact, coincident and orientation which are given by point, surface and axis system.

   Define cavity:

                       This option is used to define the cavity connection point of mounding equipment with the help representation, contact, coincident and orientation which are given by point, surface and axis system.

 Electrical assembly:

     Connect electrical device:

                  This option available in electrical assembly bench.  This option is used to connect the two electrical devices. Arter defines the electrical device if we click the part, it automatically assembles with help of point, axis, face of surface from electrical define.

    Disconnect electrical device:

                   This option is used to disconnect the two electrical devices from connected devices.

 Electrical harness assembly:

        Multi blanchable document:

                     This option is used to create the wires between the connecters. In this comment work bench different option is used to routing the wires.

        Production covering:

                       This option is used to apply the covering tubes with the help of catalogue Cot tubes.

Electrical flattening workbench:

          Harness flattening parameter:

                           When start the flattening have to set some flattening parameter by this tool.

          Extract:

                    This tool is used to take the assembly and give into this workbench.

          Flatten:

                  This tool used to flatten the assembly and create the assembly in one plane.

          Arrange junction:

                  It is used to give angle to the junction and rotate the branches of junction with respect to the angle.

          Rotate and bend:

                  Rotate option is use to rotate the wires with respect to the angle.  Bend is used to bend the wire respect to the angle.

          Roll:

             This option is used to roll the wires with respect to the angle.

Designing:

    Define the electrical device:

       Connecters:

                  

                          First create the geometry such as point, axis to define the electrical device.

               

                                                                 Then define the connecter.

               

                                                        Then give connecter connection point.

              

                           Finally, give buddle entry point and save it. We have to define the all connecter like this.

Clips:

                  

                                                      First define a part as mounding equipment.

                    

                                        Then define the cavity with help of axis, faces and point. Finally, save it.

Clamps:       

                      

                             First define the support. Then define the bundle entry point on both side with help of plane and point.

                    

                                                    Finally, give base plane reference.

Assembly:

                

                              Assemble the all connecters, clips and clamps in engine with help of assembly work bench.

Routing:

                

                                           Multi branch able tool is used to create the wire between the connecters.

Flattening:

             

                                   Set the flattening parameter and extract used to inset the harness.    

                

                                            Flatten tool is used to flatten the harness and set in one plane.     

                

                                    Rotate, bend and roll used to arrange the harness required position.                

Drawing creation:

                 

                               Create the new drawing is used to create the new drawing for flatten harness.    

                 

                                               Then change multiple option to create colour, singe line and double line drawing.

Conclusion:

              Given connecters are electrically defined and routing between the connecters and give coregulated tubes for the routing wires. Successfully flattening the harness and drawings are created for engine harness by CATIA.
