Middle wire joint and manufacturing method thereof

The invention discloses a middle wire joint. The middle wire joint comprises a middle joint body and two connected wires. The middle wire joint is characterized in that the middle joint body comprisesan injection molding shell, a middle support and two metal mounting nuts. Corresponding live wires in the two wires are in butt joint and are further riveted to metal live wire terminals, and corresponding null wires in the two wires are in butt joint and are further riveted to metal null wire terminals. The metal live wire terminals and the metal null wire terminals are both installed in terminal holes of the middle support. The injection molding shell can cover the middle support and the ends of the two wires. Meanwhile, the invention specifically discloses a manufacturing method and application method of the middle wire joint. According to the middle wire joint and the manufacturing method thereof, the parallel-type wiring power supply mode is adopted, signals are connected in series for wiring, voltage drop l
