Making Connections
4-
4.
As you bring one connector up to the other, and as you make the actual
connection, be sure the connectors align perfectly.
5.
Push the connectors straight together. Do not twist or screw them
together.
6.
Engage the connector nut over the threads on the second connector. Turn
only the connector nut. Let the connector nut pull the two connectors
straight together.
7.
Carefully align the connectors. The male connector center pin must slip
concentrically into the contact finger of the female connector.
8.
Push the connectors straight together and tighten the connector nut
finger tight. Do not twist or screw the connector together. As the center
conductors mate, there is usually a slight resistance
Final Connection Using a Torque Wrench
Using a torque wrench guarantees the connection is not too tight, preventing
possible connector damage. It also guarantees that all connections are equally
tight.
Use the recommended torque wrench to make a final connection.
provides information on the torque wrench recommended for use
with each connector type.
1.
Turn the connector nut. This may be possible to do by hand if one of the
connectors is fixed (as on a test port). However, it is recommended that
you use an open-end wrench to keep the body of the device from turning.
2.
Position both wrenches within 90 degrees of each other before applying
force. Wrenches opposing each other (greater than 90 degrees apart) will
cause a lifting action that can misalign and stress the connections of the
device involved. This is especially true when several devices are
connected together. Refer to
.
IMPORTANT!
At this point, you want a connection in which the outer
conductors make gentle contact at all points on both mating surfaces. This
requires very light finger pressure.
