Glossary of Terms
Star Clip — One of several designs used for screw
machine socket contacts. A tiny plated star shaped
clip is captivated inside a solid barrel into which the
pin contact fits. The clip creates a multi-point area
of mechanical and electrical continuity between
the mated contacts.
Stripper — A tool to remove insulation from a
wire.
Test Voltage — The range of voltages over which
the connector has been tested per the perimeters
in the applicable specification.
Thermoplastic — A plastic material that can be
softened by heat and rehardened into a solid state
by cooling. This process can be accomplished
using a variety of techniques.
Thermoset — A plastic material which hardens
when heat and pressure are applied. Unlike
thermoplastic, it cannot be remelted or remolded.
Through Hole — (Also known as a clearance hole)
A mounting hole without threads.
Turret — An interchangeable device which is
attached to a CRIMP TOOL that allows the tool to
crimp a range of contacts. Each turret is made to
crimp a specific style contact or a range of
contacts and/or wire gauges. See LOCATOR.
UL
Laboratories, a corporation supported by a group
of underwriters for the purpose of establishing
safety standards covering certain types of
equipment and components in the United States.
UL 94V-O — A flammability performance rating
set by Underwriter’s Laboratories for plastics.
V — Symbol for volt.
Vac — Volts, alternating current.
Vdc — Volts, direct current.
Vibration — A continuously reversing change in
the magnitude of a given force.
Volt — The unit of measurement of electromotive
force. It is equivalent to the force required to
produce a current of 1 ampere through a
resistance of one ohm.
Voltage — The force which causes current to flow
through an electrical conductor. Its symbol is E.
The greatest effective difference in potential
between and two conductors of a circuit.
Voltage Drop — The difference in voltage
between two points in a circuit due to the loss of
electrical pressure as a current flows through an
impedance.

Abbreviation
for
Underwriter’s
Voltage Rating — The maximum voltage which a
connector can sustain without breaking down or
varying from design specifications.
Voltage Standing Wave Ratio — If a signal is sent
down a transmission line any discontinuity will
send a reflection back in the opposite direction.
Wire Sealing Grommet — A resilient disc with
holes in it to accommodate the individual wires
entering the rear of the connector. Each cavity
forms a tight seal against the wire insulation (as
long as wires within the specified diameter are
used). The grommet seals the back of the
connector against moisture, dirt, and air. The
grommet is normally held in place and
compressed by a backshell and/or ferrule. It is
usually a separate component, but may be part of
the insulator itself. Also see GROMMET CAVITY.
Wire Size — A numerical designation for
conductor diameter. This catalog uses American
Wire Gauge (AWG) which is based on the
approximate circular mil area of the wire. See AWG
and mm
Wrap Post Contact — A type of contact which is
terminated by wrapping wire around a post in a
manner that deforms the wire and creates a gas-
tight connection between the wire and the post.
This method is slow and labor intensive. If used at
all, it is used in prototype work.
