Abstract: A plug terminal mounting arrangement includes a terminal holder base holding six terminals in respective terminal slots thereon. A U-shaped metal plate and a metal connecting block are fastened to front and rear side walls of the terminal holder base. Six U-shaped locating plates are respectively coupled between adjacent V-shaped locating blocks at the rear side of the terminal holder base. A seven-line power cord has seven wires respectively connected to the metal connecting blocks and the terminals. The V-shaped locating blocks have a partition board arranged between the legs of the V-shape for preventing the U-shaped locating plates from contacting one another. The terminal slots of the terminal holder base each having a rectangular cross section at one end adjacent the front side wall of the terminal holder base, and a T-shaped cross section at an opposite end adjacent the rear side wall of the terminal holder base. This structure of the terminal slots assists in proper location of the terminal within the terminal slots when the terminals are inserted into the terminal slots and pressed forward by a press.
