1. Hold the tool so that the back (wire side) is
facing you. Squeeze tool handles together and
allow them to open fully.
8. Holding the wire in place, squeeze tool handles
together until ratchet releases. Allow tool handles
to open and remove crimped terminal.
2. Holding the terminal by the mating end, insert
the terminal — insulation barrel first — through the
front of the tool and into the appropriate crimp
section.
NOTE
i
The crimped terminal may stick in the crimping
area, but the terminal can be easily removed by
pushing downward on the mating end of the
terminal.
3. Position the terminal so that the mating end of
the terminal is on the front side of the tool, and so
that the open “U” of the wire and insulation barrels
face the top of the tool. Place the terminal up into
the nest.
9. Check the terminal’s crimp height as described
in Section 5, CRIMP HEIGHT INSPECTION. If
necessary, adjust the crimp height as described in
Section 6, RATCHET (Crimp Height)
ADJUSTMENT.
CAUTION
!
Make sure that both sides of the insulation barrel
are started evenly into the crimping section. Do
NOT attempt to crimp an improperly positioned
terminal.
4. Rotate the tool sufficiently to be able to view the
front side of the wire crimper, and position the
terminal so that the front edge of the wire barrel is
even with the front edge of the wire crimper, as
shown in Figure 3.
5. Hold the terminal in position and squeeze the
tool handles together until ratchet engages
sufficiently to hold the terminal in position. Do NOT
deform insulation barrel or wire barrel.
6. Rotate the tool so that the back (wire side) is
once again facing you.
7. Insert stripped wire into terminal insulation and
wire barrels until the end of the wire is even with
the edge of the wire barrel and wire crimper, as
shown in Figure 3.
5. CRIMP HEIGHT INSPECTION
Crimp height inspection is performed through the use
of a micrometer with a modified anvil, commonly
referred to as a crimp--height comparator. Tyco
Electronics does not manufacture or market
crimp--height comparators. Detailed information on
obtaining and using crimp--height comparators can be
found in instruction sheet 408--7424.
Proceed as follows:
1. Refer to Figure 4 and select a wire (maximum
size) for each crimp section listed.
2. Refer to Section 5, CRIMPING PROCEDURE,
and crimp the contact(s) accordingly.
3. Using a crimp height comparator, measure the
wire barrel crimp height as shown in Figure 4. If the
crimp height conforms to that shown in the table,
the tool is considered dimensionally correct. If not,
the tool must be adjusted. Refer to Section 7,
RATCHET ADJUSTMENT.
