Back shell as a guiding supportA back shell is usually connected to a

connector through a back shell connection point and to a bundle segment through a bundle connection point.

Gives an accurate geometry.

Water-Tight Backshells

When connecting Backshells and connectors, the backshell must be selected first and then the connector to prevent the connector

from moving in the design.Connecting Single Insert Connectors

Step1. To connect two devices, click Connect Electrical

Devices.

Connect Electrical Devices Disconnect Electrical Devices

2. Select a bundle connector plug in the geometry as the first device. In this example, the connection points of both the bundle connector and the equipment connector are displayed in green, indicating that they can be connected.

3. Select an equipment connector as the second device. If the equipment connector had already been used—or if no connection

point had been defined—the connection points would be displayed as red.

4. The harness connector is now aligned properly to the equipment connector.

This is the same process used to place connectors into equipment or disconnect panels.

Disconnecting Electrical Devices 1. To disconnect electrical devices, click Disconnect

Electrical Devices . 2. Select the first device to be disconnected.3. Select the second device—or more specifically, the device

you wish to disconnect from the first device.4. The devices will disconnect, the electrical connection will

be deleted, and all assembly constraints will be eliminated from the geometry and the specification tree.

Apply Clocking Values to BackshellsThe method of applying clocking to the backshells is by using BOEBE5BSC (Backshell Clocker) to create angle constraints between the backshell and connector. This section describes using Backshell clocker for creating the clocking angles constraints on the backshells

When electrically connecting the backshell to the connector the backshell must be selected first so that the Backshell Clocker tool will calculate the clocking angle correctly.

BSC- backshell Clocker (VER 2.4.0)Every 1 hr is equal to 30º angle of clocking

Using Backshell Clocker BOEBE5BSC (Backshell Clocker) is an application that must be run in CATIA. BSC is used to record the clocking orientation of backshells to mating

connectors. BSC creates angle constraints between the backshell and connector and records the clocking

data into the in the properties window’s description field of a backshell.

Steps To Use Backshell Clocker1. Activate the GBN in the specification tree.

2. Select the Backshell clocker function.3. Select a Back Shell to be clocked in BSC dialog.

Select Allowable Clocking Values for selected backshell

Select the “Apply” button to clock the backshell

Verify the values in the backshells properties window are set correctly

Update the model& verify the backshell is correctly clocked in the geometry

Use Smart Place to Instantiate ProvisionsSmart place describes how to use Smart Place catalog browser to locate the initial

placement of harness supports, such as clamps or ring posts.

1. Switch to Electrical Harness Design workbench.

2. Activate the WHP product by double-clicking it.

3. Click Smart Place to activate the catalog browser

4. Navigate to the installation hardware chapter in the catalog browser.

Smart PlaceCatalog Browser

Double-click the Clamps chapter. Double-click the family group to activate the list of parts. In this example, BACC10NA_clamps is selected.

Click the part displayed in the catalog browser. In this example, the BACC10NA103 clamp is placed.

Move the cursor over the structure to activate the placement compass.

Click on the structure in the area where the support is to be placed to instance the clamp.

Use the compass to rotate and orient the support in correct position.

Switch to the Assembly Design workbench.

Then click Fix Component to lock the position of the attach point.

Technically speaking we should connect backshell/ strain relief first then to insert

• As backshell is used to support bundle or guid it so backshell should be given link so as to make bundle rigid and free from vibration or disconnect from connector
