Figure 1
Features of the head (shown in Figure 1) and
functions are as follows:
Feed–Through Head Assembly 58442–1 is used to
terminate discrete wires onto MTA–100 Receptacles
640620–[ ] (for wire size 22 AWG) and Receptacles
640623–[ ] (for wire size 28 AWG) with a maximum
insulation diameter of 1.52 mm [.060 in.]. Read these
instructions thoroughly before using the head.
Wire inserter—forces the wire into the two slotted
beams of the contact. Note that it provides support for
the contact beams when applying insertion force on
the wire.
Rod inserter adjuster—is a piston for the wire inserter
and regulates wire inserter travel.
The head must be mounted onto one of the following
tools (for operating procedure for the tool, refer to the
instructions packaged with the tool):
Feed slide—automatically positions the receptacle
after each termination.
— Pistol Grip Manual Handle Assembly 58074–1
(408–6790)
Locating pawl—aligns the receptacle for insertion,
and retains it during termination. The locating pawl is
sometimes referred to as the “anti–backup pawl.”
— Electric Power Unit 931800–1 (409–5746)
— Pistol Grip Pneumatic Handle Assembly
58075–1 (408–6789)
Insert housing—holds the receptacle in place in
relation to the wires.
— Pneumatic Power Bench Assembly 58338–1
(408–9393)
Wire subassembly retainer—holds the wires in place
in relation to the receptacle.
Reasons for reissue of this instruction sheet are
provided in Section 8, REVISION SUMMARY.
1. Make a termination according to Section 4,
Steps 1 through 6. If the receptacle cannot be
inserted into the head, or if the receptacle is too
loose in the head, adjust the insert housing
according to Paragraph 3.2.
The head serves as a guide and support for the
receptacle during termination.
2. After making the test crimp, depress the locating
pawl and push the receptacle out of the RIGHT
side of the head.
1. Remove the head from the tool.
2. If the wire is inserted too deep, turn the rod
inserter adjuster clockwise one–sixth of a
revolution (the wire insertion depth will be
decreased by approximately 0.20 mm [.008 in.]).
If the wire is not inserted deep enough, turn the rod
inserter adjuster counterclockwise one–sixth of a
revolution (the wire insertion depth will be
increased by approximately 0.20 mm [.008 in.]).
Refer to Figure 4.
3. Inspect the termination according to Section 5.
If necessary, make the following adjustment:
— For the manual handle assembly or electric
power unit, if the wire is inserted too deep or not
deep enough in the contact slot, adjust the wire
insertion depth according to Paragraph 3.3. Then,
repeat the termination procedure and inspection.
— For the pistol grip pneumatic handle assembly
or pneumatic power bench assembly, if the wire is
inserted too deep in the contact slot, adjust the
wire insertion depth according to Paragraph 3.3.
If the wire is not inserted deep enough in the
contact slot, increase the air pressure by 69 kPa
[10 psi], and repeat the termination and inspection
procedure 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 adjust the wire insertion
depth according to Paragraph 3.3. Then, repeat
the termination procedure and inspection.
1. Determine the wire size and select the
appropriate receptacle (receptacles are
color–coded according to wire size).
2. Install the head onto the tool according to the
instructions packaged with the tool.
3. Refer to Figure 2, and:
— for the electric power unit, insert the receptacle
into the LEFT side of head (in the direction of the
arrow) until the first contact aligns with the wire
inserter.
If the receptacle cannot be inserted into the head, or
if the receptacle is too loose in the head, loosen the
two screws on the insert housing, and adjust the
insert housing until the receptacle fits properly in the
head.
— for the manual handle assembly, pistol grip
pneumatic handle assembly, and pneumatic power
bench assembly, depress and hold the trigger or
foot pedal (the wire inserter should extend), and
insert the receptacle into the LEFT side of head (in
Figure 2
the direction of the arrow) until it stops, then
release the trigger or foot pedal (the receptacle
should advance so that the first contact aligns with
the wire inserter).
4. Check that the locating pawl is resting between
the index ribs of the receptacle. See Figure 2. If
not, push the receptacle out of the RIGHT side of
the head, and re–insert it.
5. Insert an unstripped wire into the funnel area
between the contact and the wire inserter until it is
in the desired location to be terminated.
6. Actuate the tool according to the instructions
included with the tool. When the cycle is
completed, the wire inserter will retract, and the
feed slide will automatically advance the receptacle
to the next contact position.
Figure 3
7. Repeat Steps 4 through 6 until all contacts have
been terminated.
8. Inspect each termination according to Section 5.
Refer to Figure 3, and inspect each termination to
ensure the following:
— the wire is terminated past the lead–in transition
and is about halfway in the contact slot
— the wire is from 1.78 to 2.16 mm [.070 to
.085 in.] beyond the front of the contact beam
— the wire is NOT bottomed in the contact slot
— the contact beams are NOT deformed (if
damage is apparent, replace the contacts in
accordance with the instructions packaged with the
receptacle)
Figure 4
— the wire is NOT nicked or cut in any area other
than the contact slot
The following procedures have been established to
ensure the quality and reliability of the head. The
head should be checked daily, and a more detailed
inspection should be performed by your quality control
group on a regular basis.
— the wires extend beyond the strain–reliefs of the
receptacle
Each operator should be aware of, and responsible
for, the following steps of maintenance.
1. Remove dust, moisture, and other contaminants
with a clean brush, or soft, lint–free cloth. DO NOT
use objects that could damage the head.
1. Remove any accumulated film with a suitable
cleaning agent that will NOT affect plastic material.
2. Make sure all components are in place and are
properly secured.
2. Make sure all components are in place and
properly secured.
3. Make a few test terminations, and inspect the
termination in accordance with Section 5.
3. Actuate the tool to ensure mechanisms inside
the head move smoothly.
4. Check for chipped, cracked, worn, or broken
areas. If damage is evident, repair is necessary.
See Section 7.
Regular inspections should be performed by your
quality control personnel. A record of quality control
inspections should remain with the personnel
responsible for the head. One inspection a month is
recommended; however, operator skill, amount of
use, ambient working conditions, and your company’s
established standards are all factors in establishing
frequency of inspections.
Customer–replaceable parts are listed in Figure 5.
A complete inventory should be stocked and
controlled to prevent lost time when replacement of
parts is necessary. Parts other than those listed
should be replaced by Tyco Electronics to ensure
quality and reliability. Order replacement parts
