contact installation instructions,
Individual contacts in the B
can be removed and replaced, thereby avoiding replacement
of the entire connector.
TOOLS REQUIRED:
MB, PC Series
IO Series
CONTACT REMOVAL - DB SERIES
Contact removal is accomplished from the front or mating
side of this connector series without removing the entire con-
nector from the printed circuit board. Determine which con-
tact is to be removed from the connector and cut tail.
Unsolder cut tail. Solder sucking may be necessary to clear
the printed circuit board of solder and cut tail.
Pull the contact through the front side of the connector with
tweezers. Care must be taken not to damage adjacent con-
tacts. Discard the damaged contact.
CONTACT REPLACEMENT/INSERTION - DB SERIES
Using tweezers or fingers, carefully place the replacement
contact TAIL FIRST into the appropriate contact cavity in the
front of the connector. Before final seating of the contact
make provisions for proper dressing of the contact, since the
90° tail of the DB connector must be routed through its nest in
the connector body molding and, in turn, into the printed cir-
cuit board hole.
Push the contact into the cavity with a flat-edged rod of .060
to .100 inch diameter until contact seats. Do not push against
bristle wires or bend shroud. It may be necessary to simulta-
neously bend the contact tail during this step. Dress and
resolder contact tail in proper location.
CONTACT REMOVAL - MB, PC SERIES**
Contact removal is accomplished from the front or mating
side of these connector series without removing the entire
connector from the printed circuit board. Determine which
contact is to be removed from the connector and unsolder or
unwrap the contact tail as applicable. Tail cutting and/or sol-
der sucking may be necessary to clear the printed circuit
board.
Inspect the damaged contact to determine if the bristle wires
are bent in a particular direction within the contact cavity. The
slot in the tube end of the 11-10368 Extraction Tool is
designed to accommodate these bent strands.
Retract the plunger of the 11-10368 Extraction Tool to its fur-
thest point of travel, and line up the slot in the tube end with
any bent bristle wires in the contact cavity. Insert the tool into
contact cavity. A moderate amount of resistance will be
encountered until the contact retention tines are deflected,
and then a positive stop will be felt.
