A bus duct for branching of an electrical wiring is provided to fix terminals with insulating the terminals firmly by a ceramic housing and a heat insulator and simply connect an inner connection terminal to a duct terminal. A distributor(10) includes a ceramic housing, a cross hollow unit(13), and square holes(12). The cross hollow unit is formed inside the ceramic housing(11) with an opened upper part. The opened upper part is closed when a cover(70) is fixed on an upper end of the distributor with a bolt. A conductor fixing unit(20) includes a flange(22). The flange is formed on a lower part of a cylindrical body and fixed to a center of a bottom of the cross hollow unit. A conductor includes a spherical body, a power line connection rod, and terminal connection branching tubes. A terminal socket includes an electric wire fixing unit(41) and a connection unit(42). The electric wire fixing unit is connected and fixed to an electric wire(1) by being formed on one side of the terminal socket. The connection unit is formed on the other end of the terminal socket and fixed by inserting the power line connection rod. An inner connection terminal includes a plate body, a plurality of connection plate, a plurality of separation terminal units, and a fixing unit. A heat insulator(60) is fixed with the cover by being positioned on an upper end of the inner connection terminal and insulates an upper end of the cross hollow unit by being formed in a cross-shaped plate shape. A duct(80) includes a box body, a plurality of separation holes, a separation unit, an electric wiring(84), and a duct cover(85). One end of the electric wiring is drawn outside through the separation hole and the other end thereof is fixed to a duct terminal. An upper aperture of the duct is closed by the duct cover. The duct terminal includes a square fixing plate, a plurality of connection pins, and a plurality of separation terminal units. |
