Features of the head and their functions are as
follows:
Wire Inserter—supports each wire in individual wire
slots so that, during the insertion cycle, the wire
forced into the two--slotted beam of the contact.
Wire Guide—positions the ribbon cable over the wire
inserter.
Ram—locates and holds the connector while pushing
it down onto the wires.
Locating Pawl—holds connector in proper alignment
to the wire inserter.
Push Rod—used to push the terminated connector
past the locating pawl for removal.
Insertion Rod Adjuster—is a piston for the ram and
regulates the travel of the inserted wires.
Each wire is terminated in a connector contact using
the insulation displacement technique (a terminating
technique which inserts unstripped wire into a slotted
contact beam to form a reliable electrical connection
between the wire and the contact). Contact
termination is complete when the handle assembly is
actuated.
3. SETUP
3.1. Installing Head
The head can be installed onto the handle assembly
and used as a hand--held tool, or several tools can be
mounted onto a board to be used as a low--level
harness board fixture.
