Low Mating Force Connector Installation
DAUGHTER BOARD CONNECTOR
DB connectors should be loosely held on the printed circuit board
prior to and during wave soldering. Care must be taken to ensure
that the board does not bow away from the center of the connector
during the soldering process. Also, especially on long length
daughter board connectors, care must be taken that the connector
does not bow on the circuit board. (Refer to Figure 5.)
After soldering, mounting screws should be properly
torqued.
For cosmetic purposes, the board side of the DB
connector can be masked prior to wave soldering to
protect it from heat exposure and solder wash.
Acceptable masking may be accomplished with split
tubing, stainless steel, or Mystik Tape #7010 or #7367.
(Refer to Figure 6).
Printed wiring boards with DB connectors attached
should be inserted into the housing until firmly seated.
If possible, visual observation of the MB/DB mated
condition is recommended. The fully mated condition
occurs when the DB connector skirt bottoms on the MB
or PC connector shoulder along the full length. (Refer
to Figure 7).
Printed circuit boards should be supported in card
guides and locked in position when connectors are fully
mated.
PC CONNECTOR
The PC connector should be loosely attached to the printed circuit
board prior to any soldering of contacts.
Locking bushing accessory, two per connector, may be inserted from
the back of a PC connector body into large mounting holes at each
end. See photo at right. Part number to order locking bushing
accessory for PC connectors is 10-411196-4.The 0.126 inch
diameter cross holes in the locking bushing must be aligned with the
0.126 inch diameter cross hole in the PC connector body. These
holes accept a 4–40 UNC-2A screw which should be long enough to
allow mounting to the board. Fasten with a suitable washer and nut,
making sure an appropriate washer is also under the head.
The front of the locking bushing has a 4–40 UNC-2B thread which
will mate with the locking bushing accessory of an IO connector.
