<Effects of the Invention> As is already clear from the above description, the present invention is provided with two or three parallel electric wire insertion holes for passing the FW electric wires on both the left and right sides, and the front part has holes for the electric wires to be connected. The housing includes a non-conductive housing having a beak-shaped protrusion at the tip with a terminal insertion opening for receiving a connection terminal attached to the tip, and the housing is divided vertically into a lower case and an upper case in half, and has a rear part or a front part. The upper and lower cases are integrally connected via a hinge so as to be openable and closable, and the free end edges of the upper and lower cases are formed so as to be able to maintain a closed position via a concave-convex engaging portion, and furthermore, a is equipped with at least a first crimp fitting and a second crimp fitting made of conductive material separated from each other, and these first and second crimp fittings penetrate through the housing when the upper and lower cases are closed. A terminal in which a crimping part, which is crimped to the curved surface of each covered wire to be electrically connected by tearing off the sheathing thereof, is arranged at different positions in the front and back direction on one end side, and is inserted into the other end from the terminal insertion opening. The long crimp fittings are provided with terminal connection parts that are fitted into and electrically connected to the short crimp fittings, and the long crimp fittings are provided with N electric wires to be electrically connected to the short crimp fittings at the positions of the crimp parts of the short crimp fittings. Because the structure has a detour to avoid this, two-phase or three-phase operation can be achieved with a small number of components, including an integrally molded non-conductive housing and two or three conductive crimping fittings housed inside the housing. It has now become possible to provide a wire branching device at a low cost that can immediately form a branch line from a energized covered wire of a phase without power interruption.9 Moreover, these two-phase or three-phase The outlet for the branch conductor can be formed by simply closing the housing without using any special tools for the covered wire. In addition, by fitting the terminal cover of the electric wire to be connected into the beak-shaped protrusion of the housing, the branch conductor can be arbitrarily connected and used.
This has the remarkable effect that the branch conductor does not interfere with other construction work, and the branch conductor can be removed when it is no longer needed.
