Contact Versatility - Several types of Contacts can be
designed into a Connector Shell

Nomenclature: Cylindrical Connectors and
Contacts, cont.

MIL-DTL-38999 connectors allow users to mix a variety of different power, signal, shielded, fiber optic and high speed contact
styles within a common insert.
The insert arrangement below is an arrangement for Tri-Start
MIL-DTL-38999 Series III connectors. It shows the variety of contacts that can be designed into a shell size 25. Typically, customers specify the contacts sizes and power they require and chose
an existing arrangement that fits their needs. For special new
configurations, engineering will design the arrangement of contacts to fit within material and performance criteria.

SECTION VII
Know the Language - Other Interconnection Product Terms
• Alternate Rotations - In cylindrical connectors: Rotation of
either an insert or designated key/keyway locations (Alternate
Keying) in a connector shell to a different angle than normal
position. Allows for variations of mating two halves of cylindrical connectors.
• Anodize - Formation of a protective, insulating oxide layer on
metal bay electrolytic action.
• Arc Resistance - The characteristic of insulating materials to
resist carbonization (also known as tracking) of the material
surface between electrodes resulting from voltage breakdown.
• Attenuation - (this term is used in Filters) The ratio of the
input to output power levels in a network (transmission line)
when it is excited by a matched source and terminated in a
matched load.
• Back-mounted - When a connector is mounted from the
inside of a panel or box with its mounting flanges inside the
equipment.
• Circuit - A complete path or electron flow from a negative terminal of voltage source through a conductor and back to the
positive terminal.
• Closed Entry Socket Contacts - A female contact designed
to prevent the entry of a pin or probing device having a crosssectional dimension greater than the mating pin.
• Coaxial Cable - A high-bandwidth cable consisting of two
concentric cylindrical conductors with a common axis that is
used for high speed data communication and video signals.
• Compliant Contact - A press-fit type contact used to attach
to a printed circuit board. Has an eyelet end.
• Conductivity - The ability of a material to conduct electric
current, expressed in terms of the current per unit of applied
voltage. It is reciprocal of resistivity.
• Contact Durability - Endurance measured by the number of
insertion and withdrawal cycles that a connector withstands
remaining within its specified performance level.
• Contact Engaging and Separating Force - Force needed to
either engage or separate pins and sockets when they are
out of connector inserts. Values are generally established for
maximum and minimum forces.
• Contact Resistance - Maximum permitted electrical resistance of pin and socket contacts when assembled in a connector under typical service use.
• Contact Retention - The minimum axial load in either direction that a contact must withstand while remaining firmly fixed
in its normal position within the connector insert or housing.
• Continuity - A continuous path for the flow of current in an
electrical circuit.
• Corrosion - The destruction of the surface of a metal by
chemical reaction.
• Coupling Torque - Force required to rotate a coupling ring or
jackscrew when engaging a mating pair of connectors.
• Diallyl Phthalate (DAP) - (Blue insert in 97 Series) A thermosetting plastic that offers outstanding dimensional stability
and resistance to most chemicals and chemical compounds.
• Dielectric - Any insulating medium that intervenes between
two conductors.

• Dielectric Withstanding Voltage - Maximum potential gradient that a dielectric material can withstand without
failure.
• Discontinuity - A broken connection or the loss of a specific
connection characteristic.

to a detractor, which then converts the light back into electrical signals.
• First Article - A sample part or assembly manufactured prior
to the start of production for the purpose of assuring that the
manufacturer is capable of manufacturing a product that will
meet the requirements.
• Front-mounted - A connector is front-mounted when it is
attached to the outside or mating side of a panel. (Can only
be installed or removed from the outside of the equipment.
• Front Release Contacts - Connector contacts are released
from the front side of the connector and then removed from
the back wire side of the connector. The removal tool
engages the front portion of the contact and pushes it out the
back where it is removed by hand.
• Harsh or Hostile Environment Connector - A connector

printed board assembly (printed board, component of connector) when exposed to a reduced pressure or heat, or both.
• Panel-mount - Fixing a connector half to a board, panel or
frame. Usually, the female portion of the connector is
mounted, and the male half is the removable portion.
• Plated Through-Hole - A hole-formed deposition of metal on
the sides of the hole and on both sides of the base to provide
electrical connection from the conductive pattern on one side
to that on the opposite side of the PC board.
• Poke-Home Contact - Term applied to a male or female contact to which a wire has been permanently affixed prior to the
assembly of the contact into the insert.
• Positioner - Device attached to the crimping tool to position
conductor barrels between the indentors.
• Potting - Sealing of a component (for example the cable end
of a multiple contact connector) with a plastic compound or
material to exclude moisture, prevent short circuits and provide strain relief.
• Pre-tinned - Solder applied to an electrical component prior
to soldering.
• Pre-tinned Solder Cup - Solder cups with inner surfaces that
have been pre-coated with a small amount of tin lead solder
or RoHs approved solder.
• Press-fit Contact - Either a solid pin or a pin having a compliant member that makes an interference connection with a
through-hole on a PC board. The pressure developed
between interconnecting surfaces is sufficient to provide gastight electrical reliability without the use of solder.
• Qualified Products List (QPL) - A list of commercial products that have been pretested and found to meet the requirements of a specification, especially government
specifications.
• Quick-disconnect Coupling - A design feature, apparent in
the quick-disconnect connector; it permits relatively rapid
joining and separation.

• RADSOK® Contact* - A unique socket contact design with a
stamped and formed twisted inner grid. Socket cylinder within
the female contact has several equally space longitudinal
beams twisted into a hyperbolic shape. As male pin is
inserted, axial members in the female half deflect, imparting
high current flow across the connections.
• Ramp - The sloped channel that accepts the detent pin in a
bayonet connector.
• Rear Release Contacts - Connector contacts are released
and removed from the rear (wire side) of the connector. The
removal tool engages the contact from the rear and pulls the
contact out of the connector contact retainer.
• Rear Seal - Design feature that provides an environmental
seal at the rear of plug or receptacle.
• Removable Contact - A contact that can be mechanically
joined to or removed from an insert. Usually, special tools are
required to lock the contact in place or remove it for repair or
replacement.
• RoHS (Restrictions of Hazardous Substances) - The
RoHS Directive bans the placing on the EU market of new
electrical and electronic equipment containing more than
agreed levels of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated
diphenyl ether (PBDE) flame retardants.
• Scoop Proof - Design feature whereby exposed contacts of
a connector cannot be touched or damaged by any portion of
the mating connector.
• Serrations - Small grooves or indentations within a terminal
wire barrel that increase the tensile strength and electrical
conductivity of the crimped termination.
• Soldering - Process of joining metallic surfaces with solder,
without the melting of the base metals. Soldering is an economical, versatile and fast termination method. A soldered
connection has metallic continuity and excellent long term
reliability.
• Splice Connector - A joint connecting conductors with good
mechanical strength and good conductivity; a terminal that
permanently joins two or more wires.
• Surface Mounting - The electrical connection of components
to the surface of a conductive pattern without utilizing component holes.
• Thermal Shock - The effect of heat or cold applied to a
material at such a rate that non-uniform thermal expansion or
contraction occur. In connectors, the effect can cause inserts
and other insulation materials to pull away from metal parts.
• Thermocouple Contact - A contact of special material used
in connectors employed in thermocouple applications. Materials often used are iron, constantan, copper, chromel and
alumel.
• Tuning Fork Contact - U-shaped female contact that resembles a tuning fork. It can be stamped or formed.
• Umbilical Connector - A connector used to connect cables
to a rocket or missile prior to launching, and which is removed
from the missile at the time of launching.
• Wire-Wrapped Connection (Also known as Solderless
Wrap) - A solderless connection made by wrapping bare wire
around a square or rectangular terminal with a power or hand
tool.
