The same reference numerals are used to designate the same components in the same reference numerals in the drawings of the embodiments.

The accompanying drawings are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, and are not intended to be limiting.

1 to 6, a side rail connecting module according to an embodiment of the present invention includes a first side rail 21 and a first side rail 21 of a cable tray, And the second side rail 21 adjacent to the second side rail 21.

The fastening member T is configured to connect the first side rail 21 and the side rail connection module and / or the second side rail 21 and the side rail connection module to each other. For example, T1) and the nut (T2).

However, the fastening member T is not limited to the bolts T1 and T2, and various modifications may be made to those skilled in the art, provided that the fastening member T has the same function.

The first side rail 21 and the second side rail 21 are adjacent to each other in the longitudinal direction and may have the same shape.

The side rail connection module may function as a connection part 100 connecting the first side rail 21 and the second side rail 21 which are adjacent to each other.

The side rail connection module includes a connection part 100 connected to the first side rail 21 and the second side rail 21 by the fastening member T and a connection part 100 connected to the connection part 100, And a grounding unit 200 for implementing a grounding function when an overcurrent flows in at least one of the first side rail 21 and the second side rail 21. [

For example, the connecting portion 100 may be fixed to the first side rail 21 and the second side rail 21 by fastening the fastening member T, and consequently the first side rail 21) and the second side rail (21).

The connecting portion 100 may include a body portion 110 to which the grounding portion 200 is connected and a connecting portion 130 that is bent from the body portion 110 to connect the first side rail 21 and the second side rail 21, And a bent portion 120 covering at least a part of the outer circumferential surface.

The body part 110 may have a space and a shape in which the ground part 200 can be connected.

The bent portion 120 may be bent from the body portion 110 to surround at least a part of the first side rail 21 and the second side rail 21. [

For example, the bent portion 120 may surround at least a part of the upper side and the lower side of the first side rail 21 and the second side rail 21.

Accordingly, the first side rail 21 and the second side rail 21 may be seated on the connecting portion 100 and positioned at a predetermined position.

For example, when the overcurrent flows in at least one of the first side rail 21 and the second side rail 21, the grounding unit 200 may be configured to implement a grounding function, And the like.

For example, the grounding unit 200 may be copper, copper, or an alloy. However, the grounding unit 200 is not limited thereto and may be modified in various ways insofar as those skilled in the art can implement the grounding function.

In addition, the ground unit 200 may be an elastic material that generates an elastic force.

Here, the ground unit 200 may be connected to the body 110 by interference fit.

That is, the grounding unit 200 may be connected to the connection unit 100 without interference with the body 110 without the separate fastening member T. FIG.

As a result, the grounding unit 200 is connected to the connecting portion 100 before the connecting portion 100 is connected to the first side rail 21 and the second side rail 21 by the fastening member T, ).

Therefore, the operator can connect only the connecting portion 100 to which the grounding portion 200 is fixed to the first side rail 21 and the second side rail 21, and the first side rail 21, The second side rail 21, the ground portion 200, and the connection portion 100, as shown in FIG.

Hereinafter, the connection between the connection unit 100 and the ground unit 200 will be described in more detail.

For example, the body portion 110 includes a first body portion 111 that is in contact with the first side rail 21 and the second side rail 21, and a second body portion 111 that is embedded from the first body portion 111, And a second body part 113 forming an arrangement space S1 in which the paper sheet part 200 is disposed.

For example, when the first body part 111 is connected to the first side rail 21 and the second side rail 21 by the fastening member T, the first side rail 21 and the second side rail 21 may be connected to each other. The first side rail 21 and the second side rail 21 can be prevented from being moved relative to each other by contacting the second side rail 21.

For example, the second body 113 may form the arrangement space S1 in which the ground unit 200 is disposed.

For example, the second body part 113 may be embedded in the outward direction from the first body part 111 to form the arrangement space S1.

The grounding unit 200 may be disposed on the arrangement space S1 and further may be connected to the connection unit 100 by interference with the second body 113. [

The first body part 111 and the second body part 113 may form a through hole H1 through which the fastening member T is inserted.

For example, the fastening member T is fastened to the first side rail 21, the second side rail 21, and the connecting portion 100 on the through hole H1 formed in the first body portion 111. [ The connection between the first side rail 21, the second side rail 21 and the connection portion 100 can be realized on the through hole H1 formed in the second body portion 113. Further, Can be implemented.

For example, the through hole H1 formed in the first body portion 111 may be formed at a position not overlapping the through hole H1 formed in the second body portion 113 in the height direction.

Therefore, the area where the through hole H1 is formed on the body 110 can be reduced with respect to any one axis in the height direction, and the durability of the body 110 can be enhanced.

Here, for example, the second body part 113 may form a fitting hole H2 so that the ground part 200 can be prevented.

The fitting hole H2 may be formed at a position adjacent to the through hole H1 on the second body part 113. [

The ground unit 200 may include a main body 210 receiving an overcurrent from at least one of the first side rail 21 and the second side rail 21, And protrusions 220 protruding from the protrusions 220 and being fit into the fitting holes H2.

For example, when the first body portion 111 is in contact with the first side rail 21 and the second side rail 21, The first side rail 21 and the second side rail 21, respectively.

As a result, when an overcurrent is generated from at least one of the first side rail 21 and the second side rail 21, the main body 210 may be positioned between the first side rail 21 and the second side rail 21, The grounding function can be realized by receiving the overcurrent from the rail 21. [

For example, the main body 210 may form a fastening hole H3 through which the fastening member T passing through the through hole H1 is inserted.

For example, the protrusion 220 may protrude outward from the main body 210.

For example, the protrusion 220 may be interference fit with the second body 210 on the fitting hole H2.

For example, the protrusion 220 may be formed by cutting and bending a part of the main body 210.

That is, the protrusion 220 may be formed by cutting at least a portion of the main body 210, and pressing the cut portion in the outward direction.

For example, at least a part of the main body 210 may be cut in a 'C' shape and pressed outward to be protruded from the main body 210 in the outward direction.

Therefore, the protrusion 220 can be formed only by the main body 210 without a separate member.

For example, the protrusion 220 may have a first protrusion 221 and a second protrusion 223 opposing the first protrusion 221.

The first protrusion 221 and the second protrusion 223 may be each constrained to the plurality of fitting holes H2 formed by the second body part 113. [

For example, the first protrusion 221 and the second protrusion 223 may be spaced apart from each other in the longitudinal direction.

For example, the first protrusion 221 and the second protrusion 223 may have an elastic force due to the material thereof.

Here, when the first protrusion 221 and the second protrusion 223 are constrained to the fitting hole H2, an elastic force may be generated in directions opposite to each other.

5 (c), when the protrusion 220 is constrained in the fitting hole H2, the first protrusion 221 is formed on the second body portion 113 on the left side And an elastic force to deform the second protrusion 223 in the right direction on the second body part 113 may be generated.

As a result, the ground portion 200 can be more firmly fixed on the second body portion 113.

Here, the first protrusion 221 may include a first protrusion extension 221a extending from the main body 210 and a second protrusion 221b protruding from the first protrusion extension 221a to prevent the protrusion 221 from being separated from the fitting hole H2. And a first protruding bent portion 221b formed by being bent from the first protruding portion 221a.

For example, the first protruding bent portion 221b is engaged with the second body portion 113 when an external force is applied to the body portion 210 in a direction away from the second body portion 113, The main body 210 can be prevented from being detached from the second body 113.

Like the first protrusion 221, the second protrusion 223 has a second protrusion extension 223a extending from the main body 210 and a second protrusion 223a extending from the second protrusion 223a to prevent the second protrusion 223 from being separated from the fitting hole H2. And a second protruding bent portion 223b formed by being bent from the protruding extending portion 223a.

As a result, even if an external force is applied to the ground unit 200 in the direction of releasing the fixing from the connection unit 100, due to the elastic force of the protrusion 220 and the phenomenon of being caught by the second body part 113, And can be firmly fixed to the connection portion 100.

Hereinafter, a method of performing an operation of connecting between the ground unit 200, the connection unit 100, the first side rail 21, and the second side rail 21 will be described in detail.

First, referring to FIG. 5, connection of the ground unit 200 on the connection unit 100 will be described.

5 (a) is a longitudinal sectional view showing a state before the connection part 100 and the ground part 200 are connected to each other. FIG. 5 (b) And FIG. 5C is a longitudinal sectional view showing the state after the ground unit 200 is connected to the connection unit 100. FIG. 5C is a cross-sectional view of the longitudinal direction of the ground unit 200 shown in FIG.

The operator can implement the state shown in FIG. 5 (b) by moving the connection unit 100 or the ground unit 200 in the state of FIG. 5 (a).

As shown in FIG. 5 (b), the first protrusion 221 and the second protrusion 223 may be deformed by the external force on the fitting hole H2.

For example, the first protrusion 221 may be deformed in the right direction and the second protrusion 223 may be deformed in the left direction by contacting with the second body 113 by an external force.

5 (c), the first protruding bent portion 221b and the second protruding bent portion 223b pass through the fitting hole H2, The grounding part 200 can be completely fixed to the connection part 100 by being hooked on the second body part 113.

5 (c), the first projecting portion 221 and the second projecting portion 223 may generate an elastic force in directions opposite to each other.

Here, the fitting hole H2 may be formed to expose at least a part of the main body 210 to the outside.

5 (c), the fitting hole H2 is formed to be larger than the space through which the protrusion 220 can be inserted and penetrated, so that the body portion 210 is inserted into the fitting hole H2, The operator can press the main body 210 through the fitting hole H2 from the outside.

When the worker pushes the main body part 210 from the outside through the fitting hole H2 and presses the main body part 210 with a predetermined external force or more, that is, presses the main body part 210 downward through the fitting hole H2 The ground unit 200 may be detached from the connection unit 100. In this case,

Therefore, the operator can easily fix the ground unit 200 to the connection unit 100 or release the fixing unit.

5 (c), when the protrusion 220 is constrained to the fitting hole H2, the body portion 210 is separated from the second body portion 113 The spacing space S2 can be formed.

The main body 210 may be separated from the second body 113 at least partially when the protrusion 220 is forcedly engaged with the second body 113. [

As a result, the spacing S2 may be formed between the main body 210 and the second body 113. [

For example, the main body 210 may have a downwardly curved shape as shown in FIG. 5 (c).

Therefore, due to the bent shape, the main body 210 can form the spaced space S2 between the second body portions 113 that are not bent.

Hereinafter, a method of performing the connecting operation between the connecting portion 100 and the first side rail 21 and the second side rail 21 will be described with reference to FIG.

6 (a) shows a state before the connecting portion 100 is connected to the first side rail 21 and the second side rail 21, and FIG. 6 (b) And the first side rail 21 and the second side rail 21 are connected to each other by using the connecting portion 100. [

6 (b) by using the bolts T1 and the nuts T2 in the state of FIG. 6 (a), the worker moves the connecting portion 100, the first side rail 21, The connection of the second side rail 21 can be realized.

The bolts T1 pass through the through holes H1 and the fastening holes H3 from the outer side toward the inner side so that the bolts T1 pass through the first side rails 21 and the second side rails 21, And the nut T2 is fastened to the bolt T1 that has passed through the connection hole so that the connection portion 100 and the first side rail 21 and the second side The rail 21 can be connected.

The spacing space S2 may have a first space size before the fastening member T is fastened and a second space size smaller than the first space size by fastening the fastening member T. [

6 (a), the first space size is a size of the space S2 in which the main body 210 is spaced apart from the second body 113. In other words, And the second space size is pressed in the direction of the second body part 113 by the fastening member T as shown in FIG. 6 (b) A size having a space size smaller than one space size.

The operator can adjust the second space size by adjusting the tightness of the nut T2 in the state of FIG. 6 (a).

That is, in the state of FIG. 6 (a), the operator adjusts the degree of tightening of the nut T2 to adjust the separation distances D1 and D2 between the body portion 210 and the second body portion 113 .

For example, the distance D1 between the body portion 210 and the second body portion 113 in the state of FIG. 6 (a) is larger than the distance D1 between the body portion 210 and the second body portion 113 in the state of FIG. May be greater than the separation distance (D2) between the second body portions (113).

Here, when the spacing space S2 is changed from the first space size to the second space size, the loosening of the coupling member T can be prevented.

More specifically, when the operator tightens the fastening member T and deforms the spacing space S2 so as to have the second space size from the first space size, And may have an elastic force to return to the first space size.

That is, the main body 210 generates a force in a direction to be separated from the second body part 113 due to the elastic force, so that the first side rail 21 and the second side rail 21, The second side rail 21 and the second side rail 21 are pressed against each other in a direction to be separated from the second body part 113 and the nut T2 contacting the first side rail 21 and the second side rail 21, And is urged in a direction to be spaced apart from the second body portion 113.

As a result, the frictional force between the bolt (T1) in contact with the second body part (113) and the friction between the first side rail (21) and the nut (T2) in contact with the second side rail So that it is possible to prevent the bolt (T1) and the nut (T2) from being inadvertently unwound.

Also, the spacing space S2 may have an effect of dissipating heat generated when the grounding unit 200 realizes the grounding function.

The cable tray according to another embodiment of the present invention may include the side rail module and the side rail.

The side rails may include the first side rails 21 and the second side rails 21.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be apparent to those skilled in the art that changes or modifications may fall within the scope of the appended claims.
