INSERTION
2D/CTA
EXTRACTION
1. Place the connector into the slot in the assembly block with the
arrows on the insulator pointing downward. The connector will bottom
against the internal shoulder in the groove in the assembly block. Start
contact insertion by placing the crimped contact in the cavity by hard.
2. Position the insertion tool tip on the rear of contact as shown. The
insulation must be pulled back from the crimp pot approximately 1/32"
to allow the tool tip to butt against the contact crimp pot.
3. With firm steady pressure, push the contact into the cavity until the
resilient internal shoulder snaps into the locking groove in the contact.
To prevent over insertion, the tool tip bottoms against the rear of the
insulator.

4. The guide post and polarizing posts are inserted in teh same manner
as the contacts. The guide posts are inserted into the socket insulator,
and the polarizing posts are inserted into the pin insulartor. The
corresponding contact in the mating insulator must be removed for
each.
1. To extract the contacts, place the conector face up in the assembly
block so that the contact to be extracted is in the end of the block that
has a fully slotted opening.
2. The pin extraction tool tip is tubular, slides over the pin bundle and
butts against the front shoulder of the pin. The socket extraction tool is
a solid rod that fits into the socket contact, the external shoulder butts
against the contact socket shoulder.
3. Insert the extraction tool into the cavity and apply firm pressure until
the contact is pushed thru the rear of the connector.
4. Lift the insulator from the groove and pull the contact out. Repeat for
balance of contacts to be removed.
