7000 Series Current vs. Temperature Characteristics
The thermal properties of the materials used in
the construction of a connector limit the
current carrying capacity. There are a number
of factors that determine the amount of current
that can be handled: contact spacing, size of
cable, ambient temperature and the heat that
is generated by the current passing through
the connector.
The maximum current varies with different
contact layouts, and because of these factors
it is necessary to produce de-rating curves for
each pole variant. This de-rating curve is
specified in the standard IEC 60512 part 3.
De-rating curves are plotted for each contact
carrier combination with the current being
carried simultaneously by all contacts. These
graphs show the heat rise generated as the
current is increased.
The red line indicates the direct correlation
between current applied and the measured
temperature rise within the connector. The
dotted blue line shows rated current and the
green line is derived by applying a factor of
0.8 to the original plot data to give a de-rating
curve. The dashed blue line shows the rated
current.
The shaded area under the 0.8 curve shows
the permitted operating area,
and allows safe current vs ambient
temperature characteristics to be determined.
