1. INTRODUCTION
This instruction sheet covers operation and
maintenance of MTA Terminating Head 58246–1 for
use in Pistol Grip Manual Handle Assembly 58074–1,
or Pistol Grip Pneumatic Handle Assembly 58075–1.
Read these instructions thoroughly before using the
heads. Refer to the instructions packaged with the
pistol grip handle assembly for head installation and
removal: Instruction Sheet 408–6790 (manual) and
Instruction Sheet 408–6789 (pneumatic).
Add dimensions on this instruction sheet are in
millimeters [with inches in brackets]. Figures are
for reference only and are not drawn to scale.
See Section 8, REVISION SUMMARY, for revision
information.
2. DESCRIPTION
This head is used to terminate unstripped wires in two
types of MTA–100 closed–end receptacle assemblies:
connectors with lock (ramp), and connectors with
polarizing tabs and lock. Slotted contacts for
insulation displacement termination are pre–
assembled on 2.54 [.100] centerlines in each
color–coded housing for a specific wire size. Refer to
Figure 2 and to Application Specification 114–1019 for
further details.
The head, which is inserted into the pistol grip handle
assembly, serves as a guide and support for the
connector during termination. Features of the head
(shown in Figure 1) and their functions are as follows:
Wire Inserter – forces 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.
Adjuster (Insertion Rod) – is a piston for the wire
inserter and regulates wire inserter travel.
Feed Slide – automatically positions the connector
after each termination.
Locating Pawl – aligns connector for insertion, and
retains it during termination. The locating pawl is
sometimes referred to as the “anti–backup pawl.”
3. SETUP ADJUSTMENTS AND TEST
The adjuster (insertion rod) of the wire inserter is
preset for wire sizes 22 through 28 AWG. If the wire
is being inserted too deeply or not deeply enough
inside the contact, it may be necessary to adjust the
depth of the wire inserter; or, if the pneumatic handle
assembly is being used, it may be necessary to adjust
either the air pressure or the depth of the wire
inserter.
3.1. For Pistol Grip Manual Handle Assembly
1. Determine the wire size, and select the
appropriate color–coded connector from the chart
in Figure 2. Dash numbers are used to indicate
number of contact positions.
2. Using a small knife, cut off the wire retainers
(strain relief). This will provide a clear view for
inspecting the connector for a properly terminated
wire in the contact. See Figure 3.
