IPC 620 ACTUAL FINALS ANSWERS AND QUESTIONS
SET A+
✔✔grommet - ✔✔a rubber seal used on the cable side of a connector to seal the
connector against moisture, dirt, or air
✔✔harness - ✔✔a group of wires and cables, usually made with breakouts, which are
tied together or pulled into a rubber or plastic sheath. It provides interconnection of an
electric circuit
✔✔hipot test - ✔✔a test designed wo verify the integrity of a wires insulation when
subjected to high AC or high DC voltage
✔✔hood - ✔✔type of cover to enclose wires that are assembled into a connector
✔✔hook-up wire - ✔✔a single insulated conductor used for low current, low voltage
application within enclosed electronic equipment
✔✔hot stamping - ✔✔permanent marking in letters or numbers that are stamped by
heat under pressure onto wire
✔✔hygroscopic - ✔✔the characteristic of a material to absorb moisture from the air
✔✔insulation - ✔✔a material that offers high electrical resistance making it suitable for
covering components, terminals, and wires to prevent the possible future contact of
adjacent conductors resulting in a short circuit
✔✔insulation crimp - ✔✔area of a terminal, splice or contact that has been formed
around the insulation of the wire
✔✔insulation resistance - ✔✔the electrical resistance of an insulating material that is
determined under specific conditions between any pari of contacts, conductors, or
grounding devices in various combinations
, ✔✔insulation support - ✔✔an extension of the rear portion of the contact that gives the
wire side support, but not longitudinal support. This section is not crimped
✔✔interconnection - ✔✔mechanically joining devices together to complete an electrical
circuit
✔✔interstices - ✔✔voids or valleys between individual strands in a conductor or
between insulated conductors in a multiconductor cable during extreme flexing
✔✔jacket - ✔✔an outer covering, usually nonmetallic, mainly used for protection against
the environment
✔✔jackscrew - ✔✔a screw attached to one half of a two pieced, multiple-contact
connector and used to draw both halves together and to seperate them
✔✔keying - ✔✔mechanical arrangement of guide pins and sockets, key plugs, contacts,
bosses, slots, keyways, inserts or grooves in a connector housing shell or insert that
allows connectors of the same size and type to be lined up without danger of making
wrong connection
✔✔key plug contact - ✔✔a component that is inserted to a cavity of a connector
housing or inserting to assure engagement of identically matched components
✔✔kink - ✔✔an abrupt bend from which a wire strand is not easily restored to its
original condition
✔✔lanyard - ✔✔a device attached to certain connectors that permits uncoupling and
separation of connector halves by a pull on a wire or cable
✔✔lead - ✔✔a wire, with or without terminals, that connects two points in a circuit
✔✔mastic - ✔✔a meltable coating used on the inside of some shrink products which,
when heated, flows to encapsulated the interstitial air voids
✔✔multiple-conductor cable - ✔✔a combination of two or more conductors cabled
together and insulated from one another and from the sheath or armor where used
✔✔nest (AKA anvil) - ✔✔part of crimping die set, the nest provides the location and
support for the terminal barrel as it is being deformed into the desired crimp
configuration by the indentor
✔✔O Crimp - ✔✔an insulation support crimp for open barrel terminals with a crimped
form resembling an O. it conforms to the shape of round wire insulators
