Euroblock, short for "European-style terminal block"; is a combination of a low-voltage disconnect (or pluggable) connector and terminal block commonly used for microphones and line-level audio signals , and for control signals such as RS-232 or RS-485. It is also known as the Phoenix connector and comes from a German Phoenix Electric Company, which was established in 1981 in Harrisburg, Pennsylvania, USA. Also known as "Plug-in Terminal Blocks" or "Two-Piece Terminal Blocks".
