Model 1179
Low Imparted
Impulse Connector
Qualification Status:
Qualified and flown on the
ORBCOMM satellite, Qualified and flown on the Taurus and Pegasus Launch
Vehicles.
Design:
The Model 1179 connector
uses matched internal springs, low force contacts and custom, spring-loaded
mounts to absorb perturbations, structural interference and surface
motions caused by the irregular reactive forces generated during demating.
The internal springs are sized to balance the necessary demate energy
with the sum of all energy from contact friction, external springs and
misalignment drag acting to resist the demate.
These connectors were designed
to operate in the most dynamic environments at 91.2gRMS random vibration
with shock levels over 25,000g.
In addition, the spring loaded
mounting tolerates a 5° misalignment during connector mating. The
connector is also vented to endure atmospheric decay and is outgassed
to a total mass loss less than 1% with collected volatile condensable
material less than 0.1% The Model 1179 readily incorporates G&H
Technology Breech-Lok® insert assemblies.
Shell Sizes:
13, 17 and 25. Additional
insert arrangements, other than those shown in Table I, can be specified.
