Abstract
According to an aspect of the present invention, there is provided a floor panel including a bottom surface and a side surface side rail portion extending upward from a longitudinal side end of the bottom surface, wherein at least one polygonal branch hole penetrates through the side surface side rail portion And a flexible cable connected to a front lamp that is installed on the bottom surface of the cable tray and passes through the branch hole of the cable tray and is connected to the cable tray, and the flexible cable is inserted into the cable tray, And a branch cable connector which is inserted into the branch hole and has a cap nut screwed to the other end to fix the flexible cable, wherein the branch cable connector comprises: an insertion portion inserted into the branch hole; And the screw And the insertion portion is constituted by insertion pieces corresponding to the respective line segments forming the polygonal shape of the branch hole and the end portion of the insertion piece is caught by the branch hole on the inner side of the cable tray A cable tray system for cable branching in which a slanting jaw is formed.
Description
The present invention relates to a cable tray system capable of cable branch installation.
Generally, in tunnels, factories, and offshore structures, large and small diameter cables are arranged along the ceiling, floor, and wall to supply power or fluid. The cables thus placed should not be aesthetically pleasing to the passengers. Therefore, a cable tray is used to support and fix the cable in an organized state.
The cable tray is a pipe material made of a non-combustible or metallic material for supporting a cable. The cable tray has a structure in which a pair of sideways having a predetermined length and forming left and right side portions and a sidewall portion are integrally connected to each other at the bottom, And the connecting parts are connected to each other by a horizontal connecting member which is installed at regular intervals.
The conventional cable tray may cause a safety problem such as branching by passing the side rail portion for branching to a front lamp or a branch box or the like, which is disadvantageous for aesthetics, and when a new cable tray is added, There was a problem.
It is an object of the present invention to provide a cable tray system capable of branching cables so as to be connected to side rails on the side of another cable tray from the side rails on the side of the cable tray.
According to an aspect of the present invention,
A cable tray having a bottom surface and a side surface side rail part extending upward from a longitudinal side end of the bottom surface and having at least one polygonal branch hole penetrating the side surface side part;
A flexible cable installed on the bottom surface of the cable tray, the flexible cable being connected to an electric lamp that is connected to the cable tray through the branch hole of the cable tray; And
And a branch cable connector for inserting the flexible cable therethrough and having one end inserted into the branch hole and the other end screwed into a cap nut to fix the flexible cable,
The branch cable connector includes:
Wherein the inserting portion is composed of a thread portion to be inserted into the branch hole and a thread portion to which the cap nut is engaged and a grip portion having an outer diameter larger than the outer diameter of the branch hole between the insertion portion and the thread portion, And the end portion of the insertion piece is formed with a sloped jaw so as to be caught by the branch hole on the inner side of the cable tray.
The flexible cable has a screw sleeve formed on an outer circumferential surface thereof, and one end of the cap nut holds the screw sleeve of the flexible cable.
The branch cable connector is coupled through a packing ring before the branch hole is inserted in the cable tray, and the cap nut is coupled between the branch cable connector and the packing ring via a packing ring.
It is preferable that the branch hole is formed of any one selected from a quadrangle, a pentagon, and a hexagon.
Preferably, the insertion portion of the branch cable connector has the polygonal shape of the branch hole by gathering the insertion pieces, and the contour of the inner peripheral surface of the insertion portion is cylindrical.
The cable tray system according to an embodiment of the present invention configured as described above can provide a cable tray system capable of simultaneously performing branching when an additional cable is installed after installing a cable tray.
