408-9426 Datasheet, PDF (2/6 Pages) TE Connectivity Ltd – 2 mm Common Termination Head Assembly

408- 9426
Adjustable Stop—controls the size of the connector
slot, permitting different size connectors to be
secured in head assembly.
Wire Guide—open channel into which unstripped
wire is inserted and bottomed for terminating.
Feed Pawl—when pushed forward, allows carriage
to be moved either right or left, depending on
where connector is to be located in head assembly.
The wire is terminated in the connector contact using
the insulation displacement technique (a terminating
technique which inserts unstripped wire into a slotted
contact beam to form a reliable electrical connection
between the wire and the contact). Contact
termination is complete when the tool is actuated.
3. SETUP
The setup procedure consists of determining the size
of the connector slot, securing the connector in that
slot, and positioning the connector for termination.
Proceed as follows:
1. To determine the size of slot required for the
connector to be terminated, push the feed pawl
forward and slide the carriage to the left as far as it
will go. Then loosen the socket head cap screw
located at bottom side of the adjustable stop
(shown in Figure 2), allowing the stop to be moved
right or left.
cap screw securing the connector to the head
assembly.
3. Push the feed pawl forward and slide the
carriage (with connector) to the right as far as it will
go. Then release the feed pawl. The connector is
now in position to begin termination.
4. TEST TERMINATION AND INSPECTION
At least one termination should be performed and
inspected before starting production terminating. The
steps which follow are recommended to perform the
test termination and inspection.

2. Orient the connector with the head assembly as
shown in Figure 3 — the open part of the insulation
displacement slot is up and facing the back of the
tool. Making sure that the connector slot is large
enough to accept the connector, fit the connector
in slot. Then move the adjustable stop flush
against the connector, and tighten the socket head

1. Perform the setup procedure as described in
Section 3. Note that at the end of this procedure
the connector is in position to begin the termination
process.
2. Without inserting the wire into the wire guide,
perform one cycle. The connector will be indexed
in position for the first termination.
3. Insert an unstripped wire into the wire guide until
the wire bottoms, making sure wire is centered in
the slot. See Figure 4.
4. Perform one termination cycle: the inserter will
bottom, forcing the wire between the contact slots,
and will then retract. The connector will advance to
the next contact position.
