4. CRIMPING PROCEDURE
iNOTE NOTE
This tool is provided with a crimp adjustment feature.
Initially, the crimp height should be verified as specified
in Figure 4. Refer to Section 5, Crimp Height Inspection,
and Section 6, Crimp height Adjustment, to verify crimp
height before using the tool to crimp desired contacts
and wire sizes.
Refer to the table in Figure 1 and select wire of the
specified size and insulation diameter. Strip the wire to
the length indicated in Figure 1, taking care not to nick
or cut wire strands. Select an applicable contact and
identify the appropriate crimp section according to the
wire size markings on the tool. Refer to Figure 3 and
proceed as follows:
1. Hold the tool so that the back (wire side) is facing
you. Squeeze tool handles together and allow them
to open fully.
2. Holding the contact by the mating end, insert the
contact - insulation barrel first - through the front of
the tool and into the appropriate crimp section.
3. Position the contact so that the mating end of the
contact is on the locator side of the tool. Refer to
Figure 3. Butt the contact shoulder against the
locator.
CAUTION
! Do not attempt to crimp an improperly positioned
contact.
4. Hold the contact in position and squeeze the tool
handles together until ratchet engages sufficiently to
hold the contact in position. Do NOT deform
insulation barrel or wire barrel.
5. Fully insert the stripped wire into the contact as
shown in Figure 3.
6. While holding the wire in place, squeeze the tool
handles together until ratchet releases. Allow the
tool handles to open, and remove the crimped
contact.
7. Check the contact's crimp height as described in
Section 5, Crimp Height Inspection. If necessary,
adjust the crimp height as described in Section 6,
CRIMP HEIGHT ADJUSTMENT.
5. CRIMP HEIGHT INSPECTION
This inspection requires the use of a micrometer with a
modified anvil.
iNOTE NOTE
TE does not manufacture or market these gages.
However, TE recommends the modified micrometer
(Crimp Height Comparator RS-1019-5LP).
Proceed as follows:
1. Refer to Figure 4 and select a wire (maximum
size) for each crimp section listed.
2. Refer to Section 4, CRIMPING PROCEDURE,
and crimp the contact(s) accordingly.
