Description

Description CABLE DUCT

Technical Field

[1] The present invention relates to a cable duct that is installed inside a control panel and supports cables. Background Art

[2] Many electrical parts are built in a control panel that controls various machines or automatic devices, and respective electrical parts are electrically connected to one another by cables. Svch electrical parts are generally connected to one another by several tens or hundreds of cables. In this case, cable ducts are installed so that positions of the cables can be arranged on the control panel in a narrow space.

[3] Generally, cable dvcts are installed inside the control panel while being opened to one side and constituting a τ= -shaped cross-section. Several tens or hundreds of cables are stacked on an inside of a cable dvct and are supported by the cable duct.

[4] Meanwhile, when a user wants to manufacture or replace or repair new machines or automatic devices, positions of cables connected to electrical parts must be changed, and positions of cables must be changed according to positions of electrical parts to be added or removed.

[5] However, cables having positions changed must perforate a specific portion of a cable duct and must be connected to other electrical parts. In this case, a cable hole must be formed in a specific portion of the cable duct. However, it is very difficult to form the cable hole in a cable dvct that is installed inside the control panel in a narrow space. Thus, when the user wants to change positions of cables, the cable dvct must be separated from the control panel and the cable hole must be formed in the cable dvct. Even after the cable duct is separated from the control panel, much efforts must be made to form the cable hole in the cable dvct by using a specific tool. Disclosure of Invention Technical Problem

[16] The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

[17] FIG. 1 is a perspective view of a cable dirt according to an embodiment of the present invention, and FIG. 2 illustrates a fixing portion illustrated in FIG. 1, and FIG. 3 is a front view of the cable duct illustrated in FIG. 1, and FIG. 4 illustrates a cable dirt stricture that is implemented by constituting the cable duct of FIG. 1.

[18] As illustrated in FIG. 1, a cable dirt according to the present embodiment of the present invention comprises a fixing portion 10 installed at an installation place where cables enter or go out, for example, at a control panel, and fixed at the installation place, a side wall portion 20 that is bent at both ends of the fixing portion 10, and a cover 30 that is attached to or detached from the side wall portion 20.

[19] The fixing portion 10 forms the bottom of the cable dirt according to the present invention and is fixedly installed at the control panel. A through hole which a bolt (not shown) for fixing the cable duct according to the present invention at the control panel perforates, is formed in the fixing portion 10, as illustrated in FIG. 2 The through hole may be implemented as a horizontal through hole l la and a vertical through hole 1 Ib or a circular through hole. However, when the through hole is implemented by the horizontal through hole l la and the vertical through hole 1 Ib, the cable dirt according to the present invention may be moved at regular intervals horizontally or vertically based on a bolt combined with the control panel.

[20] The side wall portion 20 comprises a bending terminal 21 that is bent at the fixing portion 10, a plurality of legs 22 that extends upwards from the bending terminal 21, a connection terminal 23 connecting ends of the legs 22, a cut groove 24 through which the legs 22 are cut from the bending terminal 21 and/όr the connection terminal 23, and a first stumbling sill 25 that is formed on the connection terminal 23 and has a dented shape along a lengthwise direction.

[21] The plurality of the legs 22 is installed while forming regular intervals between the bending terminal 21 and the connection terminal 23 so that the bending terminal 21 and the connection terminal 23 are connected to each other by the legs 22

[22] The cut groove 24 is formed at a boundary in which each of the legs 22 and the bending terminal 21 intersect with each other and at a boundary in which each of the legs 22 and the connection terminal 23 intersects with each other. The cut groove 24 is formed in the form of a groove to a smaller thickness than the legs 22 The cut groove 24 is formed in various positions, sirh as in the upper inside and outside of each of the legs 22 or in the lower inside and outside of each of the legs 22

[23] In the present embodiment, for easier explanation, the cut groove 24 is formed in the lower inside of each of the legs 22 and in the upper outside of each of the legs 22, as illustrated in FIG. 3. [24] In other words, when the cut groove 24 is formed in the lower inside of each of the legs 22 and in the upper outside of each of the legs 22, a middle portion of each of the legs 22 is cut by using scissors, a bench or nipper, and then, a cut upper leg 22a is pressurized by a finger without using a specific tool, and the upper leg 22a is separated from the connection terminal 23 and a space in which a finger may be accommodated is formed in the upper leg 22a. Subsequently, after the finger is inserted in a portion where the upper leg 22a is removed and when an end portion of a lower leg 22b is pulled out by a finger without using a specific tool, the lower leg 22b is separated from the bending terminal 21. As such, a cable hole in which cables enter or go out, is formed in the side wall portion 20 of the cable dirt.

[25] When the cut groove 24 is formed in the upper inside and outside of each of the legs

22 and in the lower inside and outside of each of the legs 22, respectively, after a middle portion of each of the legs 22 is cut by using scissors or a bench or nipper and when the cut upper leg 22a and the lower leg 22b are pressurized by a finger without using a specific tool, the upper leg 22a and the lower leg 22b are easily cut from the bending terminal 21 and the connection terminal 23.

[26] A second stumbling sill 35 of a cover 30, which will be described later, is stumbled on the first stumbling sill 25.

[27] The cover 30 is attached to or detached from the first stumbling sill 25 on the upper end of the connection terminal 23 so that cables to be stacked and arranged on the cable duct cannot be exposed to the outside. To this end, the second stumbling sill 35 that is to be stumbled on the first stumbling sill 25 is formed in the cover 30. The second stumbling sill 35 is formed so that the cover 30 is easily attached to or detached from the upper end of the side wall portion 20.

[28] When the cable duct is installed vertically or to be inclined, the cover 30 combined with the side wall portion 20 may be slid down.

[29] In order to prevent slide-down, the second stumbling sill 35 comprises a first wing

35a that is formed on the lower end of the cover 30 in a horizontal direction, a second wing 35b that is formed to be inclined to the first wing 35a, and an elastic groove 35c that is formed between the first wing 35a and the second wing 35b and allows the second wing 35b to have elasticity with respect to the first wing 35a. In addition, a protrusion is formed on one of the first stumbling sill 25 formed on the connection terminal 23 and the second stumbling sill 35 formed at the cover 30, and a protrusion groove that is to be engaged with the protrusion is formed in the other one of the first stumbling sill 25 and the second stumbling sill 35. [30] In the present embodiment, a protrusion groove 26 is formed in the first stumbling sill 25, and a protrusion 36 is formed in the second stumbling sill 35.

[31] In this way, an elastic force is applied to the second wing 35b centering on the elastic groove 35c of the second stumbling sill 35, and the protrusion groove 26 and the protrusion 36, which are engaged with the first stumbling sill 25 and the second stumbling sill 35 and increase a contact area, are formed so that, even on certain installation conditions, the cover 30 can be prevented from being slid down from the side wall portion 20.

[32] The cable dirt having the above stricture is constituted in various ways. Thus, a cable duct stricture can be implemented, as illustrated in FIG. 4, and a place (a control panel) where the cable diet according to the present invention is installed can be more cleanly arranged.

[33] The operation of the cable diet having the above stricture will now be described.

[34] In the control panel, various machines or automatic devices are electrically connected to one another by various electrical parts for controlling the machines or automatic devices and several tens or hundreds of cables, and the cables are stacked on the cable diet that is fixedly installed inside the control panel and are supported by the cable duct.

[35] When a user wants to manufacture, replace or repair new machines or automatic devices, positions of cables connected to electrical parts must be changed, and positions of cables must be changed according to positions of electrical parts to be added or removed. In this case, the cables must perforate a predetermined position of the side wall portion 20. To this end, after a middle portion of the leg 22 that the cables perforate is cut by using a simple tool, sich as scissors, a bench or nipper, the cut upper leg 22a and the lower leg 22b are pressurized or pulled out by using a finger without using a specific tool so that the upper leg 22a and the lower leg 22b are easily cut and separated from the bending terminal 21 and the connection terminal 23. As sich, a cable hole in which the cables enter or go out, is formed in the cable diet. The operation of forming the cable hole is very simple and thus, the cable diet need not to be separated from the control panel.

[36] While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the following claims. Industrial Applicability

[37] In the cable duct according to the present invention, a cut groove is formed so that a plurality of legs installed while forming regular intervals between a bending terminal and a connection terminal can be easily cut from the bending terminal and the connection terminal. As svch, a cable hole that cables enter or go out can be easily formed in a specific position without separating the cable dvct from a control panel. Thus, when a user wants to manufacture, replace or repair new machines or automatic devices, positions of cables connected to electrical parts in specific positions can be easily changed.
