てコスト、材料コストが嵩み、経済性に欠ける。In the bus duct having such a structure, when a short-circuit accident occurs and a repulsive force is generated between the conductors by the electromagnetic force associated with the short-circuit current, the conductors are likely to be bent and deformed as shown in FIG. In order to keep the bending deformation of the conductor within a range where there is no practical problem, it is necessary to reduce the arrangement interval P of the insulating spacers 2 in the longitudinal direction, and the arrangement interval P is generally about 2
It is often about 50 mm. Even in that case, the conductor deformation at the time of a short-circuit accident cannot be avoided to some extent. for that reason,
The arrangement distance D between the conductors needs to be sufficiently large. From the above, in the conventional technique, the position of the plug-in opening needs to be provided avoiding the position of the conductor insulating support member. Since the distance D between the conductors is large, the impedance is large and the impedance is large. Since the distance D between the conductors is large, the outer dimension of the duct is inevitably large, and it is difficult to make it compact. Cannot withstand excessive short-circuit current. At least when the conductor is deformed due to a short circuit, the conductor mutual distance D of the plug-in hole is D1,
Since it changes like D2, there is a possibility that the electric connection clip of the plug-in device cannot be inserted. The number of conductor insulating support members arranged increases, the assembly cost and material cost in the assembly factory increase, and the economy is lacking.

防止が図られている。The duct 3 in this embodiment is composed of a receiving gutter-shaped main body 31 made of a metal plate such as a steel plate, and a cover 32 for covering the opening side of the main body 31. A long insulating spacer 5 such as a plastic extruded material is arranged along the direction. Then, in the groove formed in parallel with the insulating spacer 5, the strip-shaped conductor 1 such as a copper plate is formed.
One side edge of the strip-shaped conductor is fitted so that the strip-shaped conductors are arranged in the plate thickness direction, and the strip-shaped insulating spacer 2 of the plastic molded body having the groove 21 is further fitted from the other side edge of the strip-shaped conductor. Has been done. The strip spacers 2 are provided at a predetermined distance P in the longitudinal direction of the conductor. In that case, a notch 11 is provided on the side edge of the conductor 2, and the strip-shaped insulating spacer 2 is fitted into the notch 11 to prevent the strip-shaped insulating spacer from being displaced with respect to the conductor.
The claw 33 is provided on the inner side surface of the strip-shaped insulating spacer 2
The locking prevents the strip-shaped spacer from shifting with respect to the conductor.

Almost no bending deformation occurs. Therefore, the mounting interval P of the strip-shaped insulating spacers for intermittent insulation support can be greatly expanded. On the other hand, the mutual distance D between the strip-shaped conductors arranged in parallel can be made smaller than the conventional bus duct because the conductor deformation due to a short circuit is almost eliminated. With such improvements, the drawbacks of the prior art can be eliminated.

供することができる。As described above, according to the bus duct of the present invention, since one side edge of the strip-shaped conductor is continuously insulated and supported in the longitudinal direction, the short-circuit strength is significantly improved. Bending deformation of the conductor due to the current at the time of a short-circuit accident hardly occurs. Therefore, the mounting interval P of the strip-shaped insulating spacers for intermittent insulation support can be greatly expanded. On the other hand, the mutual distance D between the strip-shaped conductors arranged in parallel can be made smaller than the conventional bus duct because the conductor deformation due to a short circuit is almost eliminated. As a result of such improvements, the number of intermittent insulating spacers can be significantly reduced in comparison with the drawbacks of the prior art, so the factors that hinder the setting position of the plug-in opening are reduced, and many of the insulating spacers can be placed at almost arbitrary positions. A plug-in opening can be provided. Since the distance between the conductors is small, the impedance can be reduced, and it is possible to provide wiring equipment with a small voltage drop. The outer shape can be made more compact. The short circuit strength can be significantly improved.
In combination with the reduction in the number of insulating spacers, it is possible to reduce the assembly cost and the material cost and provide an economical bus duct.
