Component Navigator content for shielding

Include entries in the Component Navigator for the two components to which the shielding connection wire attaches. If connecting to a backshell, list the backshell as a connector. If connecting to a connector, list the connector (there is an assumption that the connector would be included otherwise to support regular wires connecting to it).

Include the shield connection component, whether virtual or physical, in the component list. Shield Connection Components are assigned their Reference Designators (Pin IDs) using the Component Navigator interface, the same as other electrical components are assigned.

For example, if the format for the component list is:

connector_id, string
part_name, string

Then the entry for the shield connection component could be:

SHIELD_1, 12345678

where SHIELD_1 is the reference designator and 12345678 is the part number. For a virtual shield connection component, you can leave part_name blank.

Electrical Connection Navigator (.hrn) entry

Include an entry in the connection list to define a wire for each shield connection. Either the from connector or the to connector is the shield connection component. The other component (from or to) would be the backshell or connector.

Treat a backshell as a device (from_comp/to_comp), not as a connector (from_conn/to_conn). If the system treats it as a connector, the formboard does not lay out properly.

Assume the Electrical Connection Navigator import format is:

unique_id, string
from_comp, string
from_conn, string
from_port, string
to_comp, string
to_conn, string
to_port, string
od, real

Then an entry for a wire going from a shield connection component to a backshell (using the same values as the Component Navigator example above) might read:

SHIELD_WIRE_1, ,SHIELD_1, PIN_1, BACKSHELL_1, , PIN_1, .15

Placement

• A shield connection component can be placed on the RCP created by the Subdivide Path operation — the fixture port should point towards the component.
• Alternatively, a shield connection component can be placed near a connector, requiring no additional segment.
