Wiring duct units and wiring ducts modularized to unit lengths used for wiring and protection, more specifically, depending on the length of the wiring duct units modularized to the required unit length and the wires to be wired The present invention relates to a wiring duct configured by connecting a number of wiring duct units.

  A conventional wiring duct is provided with a cover that can be attached to and detached from the upper surface of a long duct body that is formed of an appropriate material such as plastic and has a plurality of notches (through holes) on the side surface. It is configured so that it can be inserted and wired, and the wires accommodated as needed can be drawn out from the notch and branched.

However, the above-described conventional wiring duct is always three-dimensional (tubular) and easily bulky. When a large number of wiring ducts are transported or stored, a large space is required and the integration efficiency is poor. Have.

In order to solve the above problems, for example, a wiring duct shown in Patent Document 1 has been proposed. The wiring duct has a desired length of a bottom surface, a pair of side surfaces that are foldably connected to both ends in the longitudinal direction of the bottom surface, and a foldable connection to one side surface that is detachably attached to the other side surface. The cover to be locked is plate-shaped adjacent to each other, and has a shape-retaining means that engages the engaging protrusions and keeps the bent state when the adjacent surfaces are bent and raised. To do.

In the wiring duct, the length in the longitudinal direction is formed in a long shape such as 90 cm (3 scales) or 1 m, which is a standard for construction, and is cut in accordance with the wiring length at the site. It is necessary to adjust the length. For this reason, although it can be reduced in volume, it is unavoidable that it is long in length, and is inconvenient to carry or carry.

For example, when the wiring length is 60 cm, 30 cm for a 90 cm wiring duct and 40 cm for a 1 m wiring duct must be cut and discarded, resulting in a problem of poor member yield. doing. Note that the excised wiring duct can be used in addition to the regular wiring duct when wiring the wires for a long time, but it cannot be firmly connected to each other, and there is a step at the connection location, resulting in a gap. There has been a problem in that the appearance of the image is poor.

Furthermore, in the wiring duct shown in Patent Document 1, the side plate opposed to the bottom plate is erected vertically and assembled into a rectangular cylindrical shape, and then used to accommodate electric wires through the opening in the upper side plate. doing. For this reason, since the opening width of the opposite side plate upper part becomes narrow, the operation | work which accommodates electric wires inside takes time, and there exists a problem which wiring work efficiency worsens.
