Connector Glossary
Insulation grip
The area of a crimp contact that has been reshaped
around the insulation of the conductor by compression
during the crimping operation.
Insulation resistance
The resistance of the insulation between two
conductive elements, in particular, the resistance
between two contacts or between a contact and a
metallic housing or shield. Tested according to test 3a
of IEC 60512-2 / DIN IEC 60512 Part 2.
Intermateable
Two connectors are intermateable when they
are capable of being connected electrically and
mechanically but without regard to their performance
and intermountability.
Locator
In a crimping tool the device used for positioning a
crimp contact or terminal end.
Locking lever
A mechanical locking device operated by actuating
a lever, designed to hold two mated connectors
together. Typically the lever can only be fully locked if
the two connectors are correctly mated.
Mating cycle
One mating cycle comprises one insertion and one
withdrawal operation. Term used in the denition of
connector life.
Material group
Classication of insulation materials according to their
CTI values (CTI = Comperative Tracking Index)
Overvoltage category
A numeral dening a transient overvoltage condition.
Overvoltage categories I, II, III and IV are used.
Connector with braking capacity (CBC)
A component which may be engaged or disengaged
in normal use, when live or under load. Note: In
the sense of this document the term - live- is used if
contacts are under voltage not necessarily with a
current owing across the contacts. The term - load - is
used if a current is owing across the contacts.
Rated current
A current value assigned by the manufacturer which
the connector or PSD can carry continuously (without
interruption) and simultaneously through all its contacts
wired with the largest conductor preferrably at an
ambient temperature of 40 °C without the upper
temperature being exceeded.
Shield, shielding
Shielding of internal or external electric elds by means
of a plane with a uniform electric potential, formed by
metal shells or metallic layers on the inside or outside
of plastic shells. The shield is normally connected to the
shielding braid of the cable and/or chassis ground.
Terminal block
An assembly of terminals in a housing or body of
insulating material to facilitate interconnection
between multiple conductors. Also called terminal strip
or barrier blocks if the terminals are separated by an
insulation barrier.
Wire range
The range of wire cross sections which is compatible
with the dimensions the terminals of the contact
(wire barrel). The wire range is expressed in mm2 or in
AWG numbers.
