2. Using a small knife, cut off the wire retainers
(strain relief) of the connector. This will provide a
clear view for inspecting the connector for a
properly terminated wire in the contact. See
Figure 3.
CAUTION
!
Wire retainers are removed in a connector for
testing only. DO NOT use such connectors for
production application.
3. Make a test termination according to Steps 1
through 5 of Section 5, TERMINATING
PROCEDURE.
4. Push the connector out of the right side of the
head.
5. Check that the wire insertion depth is within the
dimension given in Figure 3.
NOTE
i
To obtain the wire insertion depth, measure from
the front of the contact beam to the center of the
wire as shown in Figure 3 - or - measure from
the front of the contact beam to the back of the
wire and subtract the wire diameter divided by 2.
If it is not, proceed as follows:
For the manual handle assembly, refer to
Section 4, WIRE INSERTION DEPTH
ADJUSTMENT.
For the pneumatic handle assembly, if the wire is
inserted too deeply (more than the required wire
insertion depth), refer to Section 4, WIRE
INSERTION DEPTH ADJUSTMENT. If the wire is
not inserted deeply enough (less than the required
wire insertion depth), increase the air pressure by
69 kPa [10 psi]. Repeat the termination procedure
and check the insertion depth. Continue in this
manner until either the proper insertion depth is
obtained or the air pressure is set to 483 kPa
[70 psi]. If the proper insertion depth is NOT
reached at 483 kPa [70 psi], return the air pressure
to 276 kPa [40 psi], and refer to Section 4.
6. Inspect the termination according to
Paragraph 3.2.
3.2. Termination Inspection (Refer to Figure 3)
NOTE
i
Refer to 114- 1020 for detailed explanation of the
termination inspection requirements.
1 — The required wire insertion depth is within the
dimension given in Figure 3 (refer to Step 5 of
Paragraph 3.1 for measurement).
2 — The end of the wire extends past the contact
beam by at least 1.52 mm [.060 in.].
