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

WIRING HARNESS

wiring harness is the process of systematic arrangement of all wires and cables as a single organised unit with in a bundle of insulating material. the purpose of wiring harness is to transmitting the power of electrical signals from one location to another location of device to run the operation.

CONNECTORS

connectors are the electrical components which are connects or joints the other wires ,cables , and other suitable terminal connectors based on necessity in other end.

connectors are most flexibly used components to branching and connecting other wires . there are many types of connectors available for automotive purposes.

clips and clamps:

they are supporting parts for the connectors in wiring harness. in a vehicle there are a lot of applications available and using many connectors through out the vehicle. but for every connector needs the support or any mounting to fix it rigidly in the given location. for that we are using many connector clamps and clips.

PROCEDURE :

DEUTSCH DT06 - 08sA

.First create a point on the normal face of the connector

. create axis system with respect to the created point as a representation. As below

after defining all the geometrical parameters, now switched into the electrical part work bench.

connector definition:

now the connector defined as the electrical connector in the electrical part work bench by selecting the connector definition.

where it is asking type , part number and number of terminations. enter as per required.

BUNDLE CONNECTION POINT:

. define the bundle connection point in the bundle connection side by choosing appropriate side and respective geometric parameters.

CONNECTOR CONNECTION POINT:

.define the connector connection point in the connector coming side by selecting the created point contact face, coincidence side and orientation as below.

2. Tyco 174357-2

in our challenge the second one is the Tyco 174357 connector

first download the available connector 3D file from the source.

. create the midpoint by selecting the either the normal face both sides of connector.

. create the point for connector connection point

. create the point for bundle connection point in the bundle side.

. create the point for cavity connection point in the side of where the mounting clip housing provided.

AXIS SYSTEM

. create the proper axis system by selecting the origin or representing points available on connectors for connector connection.

create the axis system for cavity connection provided on it.

axis must be followed some assembly and electrical constrain factors to assemble properly.

now switched into the electrical part design.

connector definition:

now the part has to be defined as the connector

.create the bundle connection point by considering contact, coincidence and orientation.

. create the connector connection point by taking the point and axis system provided for it.

. create the cavity connection point in the cavity mounting side by taking provided point and axis system as a reference.

3.TYCO 85229_1

. create the mid point for cavity connection point at the mounting place

. create the axis system with respect to the point .the axis orientation and coincidence of connector and connector clip should be in same direction.

now switched into the electrical part design.

create the cavity connection point with respect to the point and axis system provided on connector clip.

now connector and connector mounting clips are readily available to assembling together.

so , now switch into the electrical assembly design work bench.

ELECTRICAL ASSEMBLY DESIGN :

. now import the both readily available parts into the product design workbench.

. positioning the connector clip exactly the way it has to assemble towards the connector mounting hose.

select the connector electrical device and click on the connector clip and connector,there showing the connector cavity point in active mode.

. click on ok then it is assembled together as below.

CONCLUSION

in this challenge the available 3D cad file was made into the defined electrical connector for using in wire harness process by suing geometrical and electrical parameters.
