Cavity Component Management
Manually Overriding Cavity Component Selections
You can override the automatic selection of cavity components, and manually specify the terminals, seals, and plugs for a cavity/wire combination.
It is also possible to interactively add terminal and seals, with associated part numbers, into empty cavities that do not have terminating conductors. This is to comply with specific aerospace industry regulations.
Prerequisites
The Cavity Component Management Dialog Box is open.
Generate Combinations and Select Parts has been run.
Valid components have been auto selected and are available to be overridden, see Automatically Selecting
Cavity Components
Note
Cavity plug selection behaves differently to terminal and seal selection.
This is due to the way each of the cavity components are stored
(terminals and seals have a wire present in the cavity and plugs do
not).
Where a cavity plug is stored there is no method to
identify if the plug has been manually placed or automatically placed in
that cavity.
Procedure
Follow the steps as appropriate:
If you want to ... Do this... Override Terminal or Seal selection Note The check box in the Terminal / Seal field indicates that a terminal / seal is to be auto-selected. In the required cavity row Terminal / Seal field, clear the check box and click the Edit button, (). The Select Part Dialog Box is displayed. The Matching Wire Specifications table shows terminals / seals which are in the housing definition and their wire specification matches the specification of the wire in the cavity. The Non-Matching Wire Specifications table shows terminals / seals which are in the housing definition but their wire specification does not match specification of the wire in the cavity. Select the required terminal / seal. or Click Add to open the Part Selection dialog box where you can search for and select a terminal / seal that is not in the housing definition. Override Plug selection Note The check box in the Plug field indicates that a plug is required (this is indicated by a tool tip). Do not clear this box. In the required cavity row Plug field, click the Edit button, (). The Select Part Dialog Box is displayed. Select a plug from the connector, backshell, or device Housing Definitions table. or Click Add to open the Part Selection dialog box where you can search for and select a plug that is not in the connector housing definition.Click OK, to confirm the selection and close the Select Part dialog box.
Note Subsequent automatic cavity part selections will not override your manual selections. To return a cavity / wire / derivative combination to automatic selection, reselect the Select Term or Select Seal options as appropriate.
