5. Perform a test crimp (refer to Paragraph 3.1).
3.4. Crimp Inspection
NOTE
i
AMPLI-BOND and AMPOWER terminals provide a
“grip” on wire insulation. PLASTI-GRIP terminals
provide only a support for the wire.
6. Remove crimped terminal from dies and
visually inspect the insulation crimp portion of
terminal. The insulation crimp should “grip” wire
insulation (when using AMPLI-BOND or
AMPOWER terminals) or provide support for wire
insulation (when using PLASTI-GRIP terminals).
7. If the insulation crimp does not grip or support
wire insulation as described in step 6, loosen
socket head cap screws and set the pin-keys in
the medium position. Then follow Steps 3 and 4.
8. Make another test crimp over previously
crimped terminal.
9. Remove crimped terminal from dies and
visually inspect insulation crimp.
Inspect crimped terminals by checking the features
described in Figure 4.
NOTE
i
AMPLI-BOND terminals are shown in Figure 4.
Inspection procedure is the same for AMPOWER
and PLASTI-GRIP terminals.
Use only the terminals that meet the conditions shown
in the “ACCEPT” column. “REJECT” terminals can be
avoided through careful use of instructions in
Paragraphs 3.1 and 3.2, and by performing regular die
maintenance described in Section 4.
4. MAINTENANCEIINSPECTION
Regular inspections should be performed by quality
control personnel. A record of scheduled inspections
should remain with the dies and/or be supplied to the
supervisory personnel responsible for the dies.
10. Repeat adjustment as necessary until desired
insulation crimp is obtained. Do NOT use a tighter
setting than required.
11. Refer to Paragraph 3.4 and Figure 4 for crimp
inspection procedure.
3.3. Color Code
Terminals and dies are color coded as listed and
shown in Figure 1. The dies have the terminal size
stamped in the wire barrel crimp sections of both the
moving and stationary dies. When crimped, the wire
size will appear on both sides of the terminal wire
barrel. The wire size appearing on the crimped wire
barrel should always agree with the wire size stamped
on the terminal tongue.
Though recommendations call for at least one
inspection a month, the inspection frequency should
be based on the amount of use, ambient working
conditions, operator training and skill, and established
company standards. These inspections should be
performed in the following sequence:
4.1. Cleaning
Do not allow deposits of dirt, grease, or foreign matter
to accumulate in the die closure area, or on the
bottoming surfaces of the dies. These deposits may
prevent the dies from bottoming fully and may also
cause excessive wear in the die closure surfaces,
thereby affecting the quality of the crimp. The dies
should be wiped clean frequently with a clean cloth.
