HI/Mate-D high voltage lead assemblies, shown enlarged above left, are tested and ready to install into the No. 8 gauge cavity of a Subminiature-D connector.

These lead assemblies are, in actuality, high voltage connectors and do not rely on the dielectric strength of the Sub-D insulator. The insert serves only to hold and retain the HI/Mate-D lead assembly. No adhesives, potting or bonding are required.
