2. Description of the Related Art Conventionally, when an electric wire cable having a round cross section is branched in an orthogonal direction, a bottom view of FIG.
As shown in the side view of FIG. 1, conductor portions 3 and 4 of electric wires 1 and 2 which are orthogonal to each other are sandwiched between upper clamp member 5 and lower clamp member 6, and these clamp members 5, 6 and 7 are fastened by tightening bolts 8 and 9. Tightening, conductor parts 3, 4
A branch connection device is used in which the conductors 3 and 4 orthogonal to each other are electrically connected via the clamp member 5 by tightening and compressing the clamp members 5 and 6 on the clamp members 5 and 6.

On the other hand, in a large-capacity power system of a large-scale building such as a building, a flat cable has been actively used by paying attention to a characteristic of low impedance. When branching a cable, a similar branch connection device is required. Therefore, a branch connection device for a round cable is applied, as shown in the top view of FIG.

13 is sandwiched between a pair of clamp members 14 arranged in the vertical direction, and the clamp members 14 are
5 and the conductor portions 12 and 13 are clamped to the clamp member 14 to be compressed.
2, 13 are electrically connected via a clamp member 14,
A branch connection device having a configuration in which the periphery thereof is insulated by an insulating cover 16 is conceivable.

[0004]

However, in the configuration shown in FIG. 4, since the conductors 12 and 13 are flat, the clamp member 14 has a larger shape in the width direction than that of a round cable, and is further tightened. The number of bolts must be increased. Therefore, when used for branch connection of a large-capacity power system in a large-scale building using three-phase power,
Since it is necessary to provide a branch connection device for each phase, there is a problem that the storage space becomes very large and the number of man-hours for tightening work is significantly increased.

[0005] The present invention has been made to solve the above-mentioned problems, and the technical problem is a flat three-phase cable.
To the three-phase flat conductor in the middle of the cable,
The cross section of the flat conductor at the end of the cable is orthogonally connected for each phase.
Work time can be greatly reduced and connection can be made in a short time.
In addition, the shape of the branch connection for three phases can be reduced.
And to provide a branch connection device that flat cable.
