Cannon Trident Connectors
flanges may be mounted in front or at
the rear of the panel.
FLASH PLATING. As commonly used in
connector terminology, flash refers to
extremely thin platings of metal. A flash
plating is the minimum thickness
required to ensure complete surface
coverage. It is typically used on contacts
that will have only occasional mating and
unmating.
IEC Abbreviation for the International
Electrotechnical Commission. An
international organization, which devel-
ops standards exclusively for electrical
engineering. CENELEC is the equivalent
organization at the European level.
INSULATOR – The insulating element
into which the contacts are mounted in
a connector.
IP67 - One classification from a rating
system used in Europe covering the
environmental sealing capability of an
enclosure. The system uses two digits,
the first digit relates to the degrees of
protection the connector has from dirt
and dust under the conditions defined in
the specification. The second digit relates
to the degrees of protection it has
against moisture. The degree of
protection against dirt ranges from 1 (no
protection), to 6 (dust tight). Moisture
sealing in the specification ranges from 1
(no protection), to 8 (protected against
continuous submersion). The classifica-
tion IP67 states that the connector is
“dust-tight” (6), allowing no ingress of
dust what-so-ever, and “protected
against the effects of immersion” (7),
the ingress of water in harmful quantity
shall not be possible when the connector
is immersed in water under defined
conditions of pressure and time.
JAM NUT RECEPTACLE – A receptacle
connector that is mounted from the rear
side of the panel and is held in place by a
large hex nut (jam nut).
KEYING A method of differentiating a
connector if more than one connector
with the same sex and layout is to be
used in a system. The key is a pin which
can be located in a contact cavity or slot.
The key will prevent a connector without
a matching orifice from mating.
LAYOUT – The number, size, and geo-
metric arrangement of the contacts in a
connector. When a connector is said to
have a certain “layout” it refers to a spe-
cific contact configuration. For example,
the Snap Together Connector series has a
page of drawings showing the arrange-
ment of the contacts in the insulator.
Each of these arrangements can be
referred to as a layout.
LOCKING RING See COUPLING NUT.
PIN CONTACT The contact that has a
long shaft at the engagement end which
enters the socket contact.
PLUG – The male portion of the connec-
tor pair usually employing a coupling nut
to secure it to the receptacle half. A Plug
may have either pin or socket contacts.
POLARIZATION – Polarization ensures
that connector halves engage in such a
way that the identified contact cavities
always engage each other, A to A etc.
The connector is polarized.
POLARIZING PIN – See KEYING.
REAR MOUNTING – A receptacle that
mounts through the panel from the rear,
with its mounting flange inside the
equipment. Typically, rear mount
receptacles are slightly longer than front
mount types to allow for the thickness of
the panel. Flange mount receptacles
usually come in front and rear mount
versions. All Jam nut receptacles are
rear mount.
RECEPTACLE – The connector which
mates with the plug. The receptacle has
threads, pins or ramps that engage the
coupling nut on the plug, locking the two
halves together. A receptacle may have
either pin or socket contacts.
SHELL The outside case of a connector
into which the insulator and contacts are
situated.
SHELL SIZE – A standard system
developed for military circular connectors
for indicating the diameter of the shell.
The system is based upon 1/16”
increments, that is, a size 16 shell is
one inch in diameter.
SOCKET CONTACT The contact that
has an opening at the engagement end
to accept the pin contact.
SOLDER CONTACT A contact that is
terminated to the wire or printed circuit
with solder. The alternative is crimp
contacts to which a wire is attached
by crimping.
SOLDER CUP – The end of a SOLDER
CONTACT designed to accept a wire,
which will then be soldered to the
contact.
STAMPED AND FORMED CONTACT –
Contacts made by stamping and forming
a sheet of metal rather than by
machining metal stock.
UL Abbreviation for Underwriter’s
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.
