経済性、工事容易性を具有する。According to the rigid contact wire of the present invention, the contact wire has a groove, and the cross-sectional shape is substantially U-shaped, and the outer surface of the upper or lower side thereof has a claw portion that engages with the groove of the grooved contact wire. It has a relatively long rigid metal support that continuously protrudes along the longitudinal direction so that the claw faces toward the opening of the cavity, and a tongue piece that is inserted into the cavity of the rigid metal support. , and consists of a short ear equipped with a claw facing the claw portion, the height after assembly is much lower and smaller than that of a conventional rigid trolley, and therefore the space occupied by it is smaller than that of conventional products. It is much smaller than the previous model, making it economical and easy to construct tunnels, etc.

て組立作業が簡略化する。Furthermore, since the metal/copper support and the ear are fixed by wedge-joining the inner wall surface of the cavity of the metal rigid support and the tongue of the ear, this is compared to the conventional method using bolts and nuts. , the installation work is greatly simplified. 1 Moreover, the claws provided on the metal rigid support I are provided continuously, and the ear is a short product, which is attached to a relatively long metal rigid support at intervals along the longitudinal direction. Since the ear is connected by a wedge, the ear can be installed at any location at the construction site, which simplifies the assembly work as a whole.

Therefore, when connecting the ends of the rigid contact wire according to the present invention in series or parallel, the connection can be easily made with a metal fitting inserted into the hollow parts of both, and there is no need for conventional welding work or connection plates. This has the advantage that work such as tightening bolts and bolts can be omitted.
