Miniature (Mini) Quick-Change Applicators

The question that most frequently arises is:
“If l have a bench machine applicator for Terminal ‘A,’
can l use that applicator to apply that terminal in one
of my automatic machines (and vice versa)?” The
answer is: “Yes . . . BUT only after obtaining and
interchanging the parts required for conversion.”
Reasons for reissue of this instruction sheet are
provided in Section 4, REVISION SUMMARY.
2. DESCRIPTION
Basic differences (typically) between automatic and
semi–automatic applicator versions are illustrated in
Figure 1. Several typical strippers are shown to
indicate that there is quite a difference in side feed
stripper requirements between semi–automatic and
automatic terminating equipment. Note that the end
feed stripper spacer requirement normally differs as
well. Figure 1 also indicates that the machines in
which the applicators are used have different stroke
lengths, and therefore the applicators require different
cams. These are the parts normally involved when a
conversion is made.
To convert an applicator (or applicators), contact your
local representative, and provide the following

Operation
The terminal is fed over the anvil on
the upstroke of the ram. A terminal is
in position
before
the operator places
the wire into the target area.
The terminal is fed over the anvil on
the downstroke of the ram. There is
no terminal in position over the anvil
until
after
the operator places the wire
in the target area and depresses the
foot switch.
The terminal is fed over the anvil on
the downstroke of the ram. There is
no terminal in position until
after
the
machine places the wire in the target
area and activates the terminating
machine.
Application
The pre-feed cam is used in
semi-automatic application tooling.
This cam can be used with all
side-feed mini applicators, and with
end-feed applicators using wire size
26 AWG or smaller.
The post-feed cam is used in
semi-automatic application tooling.
This cam can be used with all
end-feed mini applicators,
except
those using wire size 26 AWG or
smaller.
The long post-feed cam is used in
automatic application tooling. This
cams is used in all end-feed and
side-feed mini applicators.
Advantage
The pre-feed cam is used with
end-feed mini applicators when
running wire size 26 AWG or smaller.
With small wire, the applicator wire
stop cannot be used for wire
positioning, and the terminal must be
used for wire placement. The
pre-feed cam must be used on all
side-feed applicators.
Use of the post-feed cam with
end-feed mini applicators tends to
eliminate terminal jamsĊincreasing
production.
The post-feed cam is not used with
side-feed mini applicators for bench
applications.
The long post-feed cam must be
used because of the automatic
placement of wire into the applicator.
In addition, this cam is used to
accommodate the longer stroke of the
terminating machine.
Disadvantage
Using the pre-feed cam in end-feed
mini applicators can cause terminal
jams. In addition, production is
decreased because of the need for
the operator to lay the wire in the
terminal. There are no disadvantages
when using the pre-feed cam with
side-feed applicators.
When using the post-feed cam with
end-feed applicators, running small
wire can be a problem. The operator
cannot feel the wire stop. There are
no disadvantages to using the
post-feed cam with end-feed
applicators when running wire size
24 AWG or larger.
The post-feed cam is not used with
side-feed mini applicators for bench
applications.
