Description / Abstract:
This SAE Aerospace Information Report (AIR) is intended to
provide guidelines to tightening methods and torque values as
applied to electrical connectors, related hardware and switches,
relays, circuit breakers and A-A-59125 type terminal boards. The
connectors and associated hardware discussed herein, are typically
manufactured from aluminum alloy, high grade engineering
thermoplastics or corrosion resistant steel and typically plated
with a protective/conductive coating. These guidelines may be used
where no rules have been mandated either contractually or
otherwise.
Purpose
To aid in the proper assembly of electrical connectors, related
hardware and switches, relays, circuit breakers and A-A-59125 type
terminal boards in order to avoid damage by over torque or the
loosening of parts while in service.
