6.4. Gaging the Crimping Chamber
Each tool is inspected for proper die closures before
packaging. An inspection should be performed
periodically to check the tool die closures for
excessive wear.
NOTE
i
The following plug gaging information for
insulation crimping chambers is provided for
customers specifically requiring this information.
If plug gaging is not required, inspect the die
closures using an alternate procedure, i.e.,
performing the Insulation Crimp Adjustment"
(see Section 5) and Visual Inspection" (see
Paragraph 6.3).
This inspection requires the use of plug gages
conforming to the dimensions listed in Figure 7. Tyco
Electronics does not manufacture or market these
gages.
To gage the crimping area(s), refer to Figure 8 and
proceed as follows:
1. Clean oil or dirt from the crimping chamber and
plug gage.
2. Cycle the SDE power unit until wire barrel dies
are bottomed. Do not apply additional pressure.
3. With wire barrel dies bottomed, inspect the wire
barrel crimping chamber using the proper plug
gage. Lift the spring–loaded locator up and hold
gage in straight alignment with the crimping
chamber. Carefully try to insert, without forcing, the
GO element. See Figure 8. The GO element must
pass completely through the crimping area.
4. Try to insert the NO–GO element. The NO–GO
element may enter partially, but must not pass
completely through the crimping area.
5. Set insulation adjustment indicator in Position 1.
Measure insulation crimping chambers with the
proper GO plug gages in the same manner as
Steps 2 and 3. See Figure 8.
6. With the insulation adjustment indicator in
Position 1, measure the insulation crimping
chambers with the proper NO–GO plug gages. See
Figure 8.
If the crimping areas conform to the gage inspection,
the tool is considered dimensionally correct. If the
crimping areas do not conform to the inspection, the
tool must be repaired. Refer to Section 7,
REPLACEMENT.
