Lesson 4/Learning Event 1
WIRE TERMINAL ENDS
Wire lug terminals are divided into two major classes: the solder type and the solderless type (also
called the pressure or crimp type). The solder type has a cup in which the wire is held by solder
permanently, whereas the solderless type is connected to the wire by special tools that deform the
barrel of the terminal and exert pressure on the wire to form a strong mechanical bond and
electrical connection. Solderless-type terminals gradually have replaced solder-type terminals in
military equipment.
