Low Mating Force Connector Installation
PC CONNECTOR, CONT.
The mounting surface to which the connector is applied
should not extend forward of the shoulder of the PC
connector. If the mounting surface does extend beyond
the shoulder, a shim (minimum 0.005 inch thick) must be
inserted between the connector body and the mounting
surface. (Refer to Figure 8). After soldering, mounting
screws should be properly torqued.
Fixturing of the PC connector and mounting surface may
be desirable to assure straightness after wave soldering.
INPUT/OUTPUT CONNECTOR
Use of mating hardware, such as locking screws, is recommended
with I/O connectors. See photo at right. Locking screw accessory, two
per connector, may be inserted into the large holes at each end of the
back of an IO connector body. Part number to order locking screw
accessory is 10-411196-4. By hand, press the locking screw firmly
down into the cavity until it reaches a positive stop. The locking screw
is then captivated in the retention system of the cavity. The front of
the locking screw has a 4-40 UNC-2A thread which will mate with the
locking bushing accessories of MB or PC connectors. (Refer to Figure
9 for I/O locking screw dimensions).
Should it be necessary to remove the captivated lock ing screw
accessory, push the screw as far forward as possi ble. Using vise grip
pliers to grasp the threaded end and pliers to hold the knurled end,
apply torque until the locking screw breaks in two. Each half will then
drop out.
Alternate Mounting Variation for Input/Output Connectors
For fixed mounting, a 6-32 thread forming screw, type AB (MS5186)
may be inserted through the mounting member and into the holes at
each end of the connector body from the back. The screws must be
used with suitable washers and must be of sufficient length to
penetrate the connector body 0.350 inch. Care must be taken not to
over-tighten the screws.
Visual observation of the mating of the MB connector to the I/O
connector or the PC connector to the I/O connector is recommend-
ed. The fully mated condition occurs when the I/O connector skirt
bottoms on the MB or PC shoulder along the full length. (Refer to
Figure 10).

Printed circuit boards containing PC connectors that
are mating with I/O connectors should utilize a
holding device that is capable of locking the board
in place to prevent back-off during use.
