Although HD–I applicators accept only certain
terminals, they provide valuable application flexibility.
The wire crimp can easily be adjusted for as many as
four different wire sizes, and the insulation crimp can
be adjusted to accept eight insulation diameters.
HD–I applicators can be used in various terminating
machines, provided that the machines have the
proper stroke length and all the necessary equipment.
NOTE
i
The applicator can be used in either 30 or 40mm
stroke terminating machines by adjusting the
position of the feed cam.
The main components of the applicators are identified
in Figures 1 and 2. The ram assembly is shown in
detail in Figure 3.
The terminal strip is fed into the applicator, from left to
right, with the wire barrel facing upward and the
insulation barrel facing toward the operator. The strip
passes under the strip drag as well as the front and
rear strip guides. The rear strip guide aligns with front
edge of the wire barrel. The lead terminal is
positioned over the anvil (for pre–feed applicators) or
one terminal pitch from the anvil (for post–feed
applicators). Pre–feed applicators (normally used for
bench machines) feed terminals as the ram moves
up. Post–feed applicators (normally used for
lead–maker applications) feed terminals as the ram
moves down. The feed pawl feeds one terminal
during each cycle of the terminating machine. The
terminals are fed by the action of the feed cam and a
series of rods and levers which move the feed pawl.
The ram post (also referred to as the ram mounting
post) engages the post adapter of the machine ram,
and it is the machine ram that actuates the applicator.
Just below the ram post are the wire disk and the
insulation crimp disk. The wire disk has as many as
four pairs of pins installed, depending on the number
of different wire sizes the terminals will accept. Each
pair of pins has a different height. By rotating the disk,
each pair of pins can be lined up with the two bosses
on the ram post adapter (see Figure 3) to change the
applicator crimp height. Some terminals accept more
than four wire sizes. Terminating additional wire sizes
will require adding or replacing pins in the wire disk.
Refer to the applicator assembly drawing and
Paragraph 7.6 for more information. The insulation
crimp disk contains eight pads of different heights.
When this disk is turned, the pads line up with the top
of the insulation crimper to change the insulation
crimp height.
