connectors transform the perpendicular compression force,
which would normally contribute to conductor creep, into distributive forces
that effectively resist cold flow, as indicated by the illustration below.
These connectors are made of copper alloy, tin plated, with a number
of teeth on the inner surface. When compressed onto an insulated
magnet wire, the sharp, hardened teeth penetrate both the insulation and
oxide and bite into the conductor. An electrically sound, low-resistance
connection is established as a result of the combination of high pressures
at the edges of the teeth, and the sliding action between the teeth and the
conductor. The open barrel design permits midspan splicing and tapping.
How to Select a Connector
Determine total circular mil area (CMA). All wires
to be installed in a connector barrel including stripped,
stranded wire. For example, two #6 AWG = 52,480 CMA.
Refer to Circular Mil column of chart and find the
connector series corresponding to the total CMA.
For example, 204XXX.
Next, refer to either Round Wire column or Rectangular
Wire column, depending on the type you are using, and
check for any limitations, (such as max. wire width/
height). If there are limitations, you may have to make
a selection from the next larger size.
Select the tool and die appropriate for the application.
