2. DESCRIPTION
The head serves as a guide and support for the
receptacle during termination.
Features of the head assembly (shown in Figure 1)
and functions are as follows:
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.
Feed slide—automatically positions the receptacle
after each termination.
Locating pawl—aligns the receptacle for insertion,
and retains it during termination. The locating pawl is
sometimes referred to as the “anti--backup pawl.”
Insert housing—holds the receptacle in place in
relation to the wires.
Wire subassembly retainer—holds the wires in place
in relation to the receptacle.
3. TEST CRIMP AND HEAD ADJUSTMENTS
3.1. Test Crimp
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.
