A: A "Stay-Cord"
is made of a strong, thread or twine which
is part of the internal construction of
heavy duty or mil-spec cordage. It is
usually different from the 'fluffy' filler
cord that is used to make a circular cross
section cable. The stay-cord's purpose
is to absorb a linear pulling force on
the cord/connector area, so that the connector
stays permanently affixed to the cord.
It also prevents any conductors or solder
connections from breaking under the same
linear strain.
Q: What is the Crimp
Ring?
A: A crimp
ring is designed to prevent the cable
from twisting inside the connector. The
crimp ring should not be used as the strain
relief feature because it will eventually
allow the cord jacket to work itself out
of the connector. This will then allow
the conductors to take the strain load
and eventually break. Also, the crimp
ring must be crimped properly to prevent
the cord from twisting inside the connector.
Using the recommended crimping dies and the properly sized
cable O.D., will provide the maximum twist
relief without damaging the cord.
Many customers
ask what kind of cable they should use
with our connectors. Back in the 'old
days' we may have had a few suggestions,
but nowadays there are so many different
types of cables out there. The only thing
we can suggest is that the cable should
be round in most cases, it should have
a stay-cord, and that it should be durable.
There are quite a few manufacturers out
there, but below are a few cordage manufacturers
that have web sites that you can visit.
As for
wiring of our connectors, this too has changed
over the years. Our best recommendation
is to contact the manufacturer of the equipment
that you are attempting to interface to.
However, if you have ANY questions about
cabling our connectors, please contact us
and speak with our applications and engineering
department. We would be happy to assist
you.
