Alternate Mounting Variations for Mother Board Connector
A clinch nut (such as all ESNA 79NCFMA2-26 or equiva lent may be
pressed from the front, knurled end first, through the 0.185 diameter
CSK into the 0.122 inch diameter hole at each end of the connector.
An appropriate length 2–56 UNC-3A screw, washer, and nut may be
used to mount the con nector. Mounting forces should be applied to
the bushing toward the rear of the connector. (See Figure 2 below)
Low Mating Force Connector Installation
MOTHER BOARD CONNECTOR
MB connectors that are mounted on printed circuit boards should be
installed on the board and held somewhat loosely, yet assuring all
connector molding standoff pads contact the surface of the board,
prior to soldering. There are several methods for attaching the MB
connector to the board.
Inserting locking/mounting bushings with an arbor press is shown in
the top photo at right. Locking/mounting bushing accessory, two per
connector, may be inserted into 0.185 inch diameter CSK holes at
each end of the front of a MB connector body. (Part number to order
locking/mounting bushing is 10-41196-3). Using a light arbor press
or similar device, firmly press the knurled section of the bushing into
the lower 0.122 inch diameter hole until the front of the bushing is
flush with, or slightly below, the front surface of the MB connector.
Refer to Figure 1 at right.
Make sure the bushing and hole axis are properly aligned. Avoid
excessive force which may crack the back surface of the MB
connector body.
The back of the locking/mounting bushing has a 4–40 UNC-2A THD
to mount the connector. Fasten the connector with a suitable washer
and nut. The front of the locking/mounting bushing has a 4–40
UNC-2B THD which will mate with the locking screw accessory of an
IO connector.
When a Daughter Board is mated, use a 4–40 screw of appropriate
length with a suitable washer under the head. Insert the screw from
the front of the connector through the 0.185 inch diameter CSK into
the 0.122 inch diameter hole at each end of the connector and fasten
with a suitable washer and nut. (Refer to Figure 3 below). Torque to
5.5 pound-inch maximum after soldering operation has been
completed.

If MB connectors are to be wave soldered to printed circuit
boards, the boards should be fixtured to maintain assembly
straightness prior to and during the wave soldering process.
