Description

[Detailed description of the invention] [Object of the invention] (Industrial application field) The present invention
Stores power cables and signal cables connected to devices,
The purpose of this invention is to provide a system duct suitable for arranging these cables on the floor, desk, etc. in a good manner and connecting them to OA equipment.

(Prior Art) Conventionally, in rooms where a large number of so-called office automation equipment such as personal computers (hereinafter referred to as personal computers) and word processors (hereinafter referred to as word processors) are installed, it is difficult to connect power cables. requires numerous electrical outlets. Furthermore, in order to connect power cables and signal cables to OA equipment, it is necessary to wire a large number of cables. Therefore, in order to install these outlets and cables on the floor of the room, generally,
Predetermined ducts were placed on the floor, cables were routed inside the ducts, and outlet boxes were installed at predetermined positions of the ducts.

(Problems to be Solved by the Invention) However, when the outlet box is installed in the duct, the outlet box protrudes largely from the opening side of the duct. Therefore, when a large number of boxes are installed along the duct, these boxes become extremely bulky and require a large amount of space for installing the boxes.

Also, since the box is installed at any position of the duct opening, in order to cover the duct opening other than the position where the box is installed, the duct cover must be cut to match the length of the duct opening. The box itself was an obstacle to attaching the cover. Therefore, it takes a lot of effort to cover the duct, and if the duct is not covered, the cables are exposed and attract attention, which spoils the appearance.

Moreover, as the number of office automation equipment increases, wiring is frequently added or changed, but with conventional ducts, when a new outlet is installed, a new one that matches the new shape of the duct opening is required. It is necessary to attach a duct cover, and such conventional duct wiring has the disadvantage that it cannot be adequately adapted to the addition or change of cables.

Therefore, the present invention was created to solve the above-mentioned problems, and provides a system duct that improves the appearance of this type of cable wiring and also allows for extremely easy installation and modification of new outlets, etc. With the goal.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a suitable number of partition plates along the longitudinal direction inside a duct of a predetermined width to connect a power cable. A storage section and a signal cable storage section are provided separately, and a cover unit that is detachably attached to the duct opening and a connection unit in which a cable connection device is attached to this cover unit are installed along the longitudinal direction of the duct opening. The solution to this problem is to install an appropriate number of units and cover the duct with these cover units and connection units.

(Function) According to the present invention, the inside of the duct is partitioned along the longitudinal direction by an appropriate number of partition plates, and a power cable storage section and a signal cable storage section are provided separately.
