2. DESCRIPTION

The head serves as a guide and support for the

receptacle during termination.

Features of the head (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

loose in the head, adjust the insert housing

according to Paragraph 3.2.
