JUNCTION BOX
A box with a cover that serves the purpose of joining different runs of wire or cable and provides space for the connection and branching of the enclosed conductors [4].
JUNCTION DIODE
A two-terminal device containing a single crystal of semiconducting material that ranges from P-type at one terminal to N-type at the other [7].
JUNCTION TRANSISTOR
A bipolar transistor constructed from interacting PN junctions. The term is used to distinguish junction transistors from other types, such as field-effect and point-contact [7].
