AIRCRAFT APPLICATIONS

Positronic Industries’ grounding plates were designed especially for aircraft applications where shielded cable must be
grounded to the aircraft frame. The ground wires of the shielded cable are piggy-backed out of the cable with ferrules and are
crimped to Size 16 female contacts. The female contacts are
loaded into standard 14 or 34 contact connector housings.
These connectors can then be mated to the grounding plate
which is fastened to the aircraft frame.
Grounding plates have Size 16 precision-machined male
contacts which are swaged and soldered onto the metal plate.

Rectangular

The metal plates (angled and plane) have fixed female
jackscrews that accept the rotating jackscrews, which are an
integral part of the mating female connector. Long rotating
jackscrews extend beyond the edge of the cable adapter of the
14-contact female connector which permits easy coupling to
the grounding plate.
Other contact variants are available for grounding plate applications. Contact Technical Sales for information on the availability of other grounding plates offered by Positronic Industries.
