GLOSSARY OF TERMS
In every job speciality there are certain
words and phrases used by “insiders”
which after a time become almost a
language unique to that speciality. Trident
technology is a typical example of that
condition.
This page provides some explanations, in
an attempt to clarify some of the terms
that are commonly used by engineers and
sales staff at Cannon.
The list is not comprehensive, but high-
lights many of the expressions commonly
used. Should you have any comments or
additions please contact us. Feedback will
be appreciated.
ADAPTER – A device used to modify the
accessory threading on the rear of the
connector. Typical adapters are used to
attach conduit, heat shrink, overmolds,
or tubing to the connectors. They are
generally used in place of a cable clamp.
AWG – American Wire Gauge. A method
of specifying wire diameter. The higher
the number, the smaller the diameter (a
size 16 AWG wire has a larger diameter
than a size 22 AWG).
BAYONET COUPLING – A quick coupling
mechanism for mechanically mating and
unmating connector halves. The plug
half has a coupling nut with internal
ramps and the receptacle has three
“bayonet” pins. The two halves are
mated and unmated by rotating the
coupling nut. The two haves are mated
and unmated by rotating the coupling nut.
BACKSHELL – See ENDBELL.
BODY - The main portion of the connec-
tor made of the shell, insulator, and con-
tacts.
CABLE CLAMP – A rear connector
clamping accessory which tightens over a
cable or wire bundle to provide strain
relief to the cable. The cable clamp may
be part of a more elaborate endbell or it
may be used alone. Some cable clamps
also provide cable jacket sealing using a
resilient gland, others provide only strain
relief.
CABLE SEAL – An endbell or cable
clamp that is used to seal a round
jacketed cable as it enters the rear of
the connector.
CONTACT – The conductive element in
a connector which makes the actual con-
nection between the wire and the mating
connector for the purpose of transferring
electrical energy. Ideally the contact
should add nothing to the circuit. In the
real world, however, contacts typically
have a small CONTACT RESISTANCE and
associated potential drop. Contacts come
in many styles such as solder, crimp,
printed circuit (PC), to name just those
found in this catalog. Also see SOLDER
CONTACT, CRIMP CONTACT, STAMPED
AND FORMED CONTACT, PIN CONTACT,
and SOCKET CONTACT.
CONTACT ALIGNMENT – The overall
play that a contact has in the insulator
cavity to allow the mating contacts to self
align. Also called contact float.
CONTACT ARRANGEMENT – See LAYOUT.
CONTACT CAVITY – A defined hole in
the connector insulator into which the
contacts fit. The cavities are generally
marked with a unique designation or
number for ease of identification.
CONTACT RESISTANCE – The maximum
amount of resistance which a contact
introduces into the connection when
carrying a specified current (usually stated
in milliohms). When not stated, values
are typically given for “Initial” or new
contacts. Most specifications also limit
the maximum resistance during or after
each of a series of extreme tests, such as
“Contact Resistance After Corrosion Test”.
These figures are typically slightly higher
than “Initial”.
CONTACT RETENTION – The maximum
allowable axial load which can be applied
to a contact from either direction without
it being dislodged from the insulator.
Usually stated in Newtons or pounds of
force (4.45 = 1 lbf).
CONTACT SEPARATION FORCE – The
force required to separate a pair of mated
contacts. Usually stated in grams or
ounces.
CONTACT SIZE – The size of the
engaging pin and socket contacts in
AWG size or metric diameter of the pin.
CONTACT SPACING – The distance
between two centers of adjacent
contacts.
COUPLING NUT (Also known as LOCK-
ING RING) - The rotating ring on plug
style connectors which mechanically locks
87
the two connector halves together.
CRIMP CONTACT – A contact which is
terminated to a wire by means of
mechanical deformation of the receiving
area by means of an appropriate tool.
CSA – Abbreviation for Canadian
Standards Association.
CURRENT RATING – The maximum
current that a particular wire, contact,
or connector can accommodate. NOTE:
When several wires are used in a single
connector or elevated temperature or
altitude is involved, derating curves must
be applied to these ratings.
DERATING CURVE – A graph of the
change in power handling capability of a
connector as a function of ambient tem-
perature or altitude. Typically the graphed
function is curved, hence the name.
DISCRIMINATION – A method of
ensuring that two similar size connectors
cannot be mated. This may be achieved
by inclusion of discriminating pins, which
enter an empty contact cavity, or by other
mechanical means.
DISCRIMINATING PINS – See KEYING.
ENDBELL (also know as BACKSHELL) –
The outer rear end of the connector,
which is attached by means of internal
threads or screws. It adapts the connec-
tor to its wire connections in a variety of
ways. Typical endbells might have cable
clamps to secure a wire bundle, ridges for
heat shrink tubing, pipe threads, or shield
termination mechanisms.
EXTRACTION TOOL – A device used to
remove a contact from a connector
insulator. The extraction tool is inserted
into the mating face of the insulator and
the contact comes out the rear, or wire
side, of the connector.
FIRST-MAKE LAST-BREAK CONTACT –
A contact which is longer than a standard
contact or which sits in the insulator in
such a way that it mates with the
opposing connector half before any of
the other contacts. Used to ensure that
a ground connection between the
connector halves mates before any of the
other contacts.
FLANGED RECEPTACLE – The shell of
this connector has a square flange with
mounting holes at each corner.
Mounting holes are usually clearance
holes, but may be threaded. Receptacle
