Claims

[Scope of utility model registration request]

Upper and lower insulating holders are placed at a required distance in the longitudinal direction within a housing formed by integrally forming a top plate, both side plates, and an inner folded part of the bottom by bending a metal plate, and a conductor is inserted between these insulating holders. In the bus duct in which a bottom cover plate is bolted to the inner folded portion of the bottom via a gasket, cutouts for locking the lower insulating holder are formed at required intervals in the inner folded portion of the bottom of the housing. A protrusion is formed on the inner surface of the top plate of the housing at a position corresponding to the notch, a retaining part that engages with the protrusion is provided on the upper insulating holder, and the lower insulating holder is attached to the notch. 1. A bus duct comprising a conductor and each insulating holder fitted into a housing such that the conductor and each insulating holder are locked and a retaining part of the upper insulating holder engages with the protruding part.
