[

Hereinafter, the side rail R, the connecting device 100, and the grounding device 200, which are components of the cable tray, will be described in detail.

For example, the side rails R may be arranged in parallel in the longitudinal direction.

For example, the side rail R may form a connection hole H1 in which the connection fastening portion 160 to be described below is fastened.

For example, the side rails R may be formed with a plurality of fastening holes H2 through which fastening members such as bolts, screws, etc. may be fastened so that the connecting device 100 described below may be fixed.

For example, the connecting device 100 may be a device for connecting the side rails R adjacent in the longitudinal direction.

For example, the connecting device 100 may be fastened to the plurality of the side rails R by the fastening member to realize the connection between the adjacent side rails R.

The connection device 100 includes a connection main body 110 which covers at least a part of the side rail R and a connecting member 110 which is bent from the connection main body 110 and is arranged on the upper side of the side rail R And a lower bending portion 130 bent from the connection body portion 110 and covering a lower side of the side rail R. [

As a result, the connecting body portion 110, the upper bending portion 120, and the lower bending portion 130 may surround at least a part of each of the neighboring side rails R. [

The connection device 100 may further include the connection coupling part 160 protruded from the connection main part 110 and inserted into the connection hole H1.

For example, the connection coupling part 160 may protrude inwardly from the connection body part 110 in which the side rail R is located, and may be bent in the longitudinal direction.

As a result, the connection coupling part 160 may be inserted in the connection hole H1 of the side rail R, and then may be moved in the longitudinal direction to surround the side rail R. [

The connecting device 100 may fix the neighboring side rails R when the connecting fastener 160 is moved in the longitudinal direction to surround the side rails R. [

For example, the connection coupling part 160 may be formed by cutting and bending a part of the connection main body part 110.

The operator can firmly fix the connecting device 100 and the side rail R using the fastening member in a state where the connecting device 100 fixes the side rails R therebetween.

The connection device 100 may further include a connection insertion portion 140 that is inserted from the connection body portion 110 and provides an insertion space S1 into which the grounding device 200 is inserted have.

For example, the grounding device 200 may be disposed between the side rail R and the connecting device 100.

Accordingly, the connection concave portion 140 can form the recessed space S1 in which the grounding device 200 can be disposed.

For example, the grounding device 200 may be disposed on the recessed space S1 and may be grounded by contact with the side rail R. [

In this case, for example, the connection recessed portion 140 forms a through space S2 through which the ground protruding portion 220, which will be described below, is inserted so that the grounding device 200 is fixed on the recessed space S1 can do.

The grounding device 200 may be fixed to the connecting device 100 when the grounding protrusion 220 penetrates the penetrating space S2 and is connected to the connecting recessed part 140. [

For example, the grounding device 200 may be disconnected from the connecting device 100 when the grounding protrusion 220 is detached from the penetrating space S2.

Here, the through-hole S2 may include a first through-hole S2-1 through which the ground protrusion 220 is inserted, and a second through-hole S2 S2 through which the ground protrusion 220 is inserted -2).

More specifically, the ground protrusion 220 can be inserted into and / or removed from the first through-hole S2-1 on the first through-hole S2-1, and the second through- S2-2 of the second through-hole S2-2.

As a result, when the grounding protrusion 220 is inserted into the first penetrating space S2-1 and then moved to the second penetrating space S2-2, the grounding apparatus 200 is connected to the connecting apparatus 100, Can be fixed.

Conversely, when the ground protrusion 220 moves to the first through-hole S2-1 on the second through-hole S2-2, the ground protrusion 220 can be separated from the first through-hole S2-1, As a result, the grounding device 200 can be disconnected from the connecting device 100.

Here, for example, the second through-hole S2-2 may be formed below the height direction of the first through-hole S2-1.

For example, the longitudinal width of the second through-hole S2-2 may be smaller than the longitudinal width of the first through-hole S2-1.

As a result, when the ground protruding portion 220 is moved downward in the longitudinal direction after passing through the first through-hole S2-1 and moved onto the second through-hole S2-2, The grounding unit 220 may be fixed to the connection concavity 140 to implement the fixing of the grounding unit 200.

Therefore, in order to fix the grounding apparatus 200 to the connection apparatus 100, the operator merely inserts the grounding protrusion 220 into the first through-hole S2-1, (S2-2).

Also, since the grounding protrusion 220 is continuously disposed on the second through-hole S2-2 due to its own weight, the grounding apparatus 200 fixed to the connecting apparatus 100 in this manner is continuously disposed, The connection device 100 can be prevented from being inadvertently detached from the connection device 100.

Here, the connection device 100 may include a connection protrusion protruding from the connection insertion portion 140 so that the grounding device 200 is not moved in a state where the grounding device 200 is fixed in the insertion space S1, And a connection insertion part 150 inserted into the fixing hole H5 of the grounding device 200. [

For example, the connection insertion portion 150 may protrude inward from the connection recess portion 140 toward the grounding device 200.

The relationship between the connection inserting part 150 and the fixing hole H5 will be described in more detail below.

For example, the connection main body 110 may form a first connection hole H3 through which the connection member can be fastened. Further, the connection insertion portion 140 may be formed with a hole The second connection fastening hole H4 can be formed.

Therefore, the fastening member can be fastened to the fastening hole H2 through the first fastening hole H3 and further fastened to the fastening hole H2 through the second fastening hole H4 It is possible.

As a result, the connecting device 100 can realize the connection between the side rails R neighboring in the longitudinal direction.

Hereinafter, the grounding device 200 will be described in detail.

For example, the grounding device 200 may be a device that contacts the side rails R neighboring in the longitudinal direction to implement the grounding.

The grounding device 200 may include a grounding body portion 210 that contacts the side rail R to implement grounding and the grounding protrusion 220 that protrudes from the grounding body portion 210. For example, have.

For example, the ground main body 210 may be in contact with each of the side rails R to realize a ground.

For example, the ground main body 210 may be inserted into the insertion space S1.

For example, the ground protrusion 220 may protrude outward from the ground body 210 toward the connection device 100.

For example, the ground protrusion 220 may protrude outward from the ground body 210 and be bent in the longitudinal direction.

Therefore, the ground protrusion 220 can be fixed to the connecting device 100 through the through space S2.

That is, the ground protruding portion 220 may be moved downward in the height direction on the through-hole S2 and fixed to the connecting device 100. [

For example, the ground protrusion 220 may be detached from the connection device 100 on the first through-hole S2-1 and may be moved downward from the first through-hole S2-1, 2 through-hole S2-2, the connecting device 100 may be fixed.

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

In more detail, the operator can cut a part of the ground main body 210 and bend the cut part inward to form the ground main body 210.

As a result, the grounding body 210 may form a cutting space S3 at a point where the grounding protrusion 220 is formed.

In this case, the height direction width K1 of the cutting space S3 may be larger than the height direction width K2 of the ground protrusion 220, for example.

A burr-like protrusion may be formed at the edge of the ground main body 210 defining the cutting space S3 in the process of cutting to form the ground protrusion 220 have.

In addition, a burr-like protrusion may be formed at the edge of the connection recess portion 140 defining the through-hole S2 in the process of cutting to form the through-hole S2.

In the case where such a protruding portion as the unintended burr is formed, in a state where the protruding portion is not sufficiently moved from the first through-hole S2-1 to the second through-space S2-2, the ground protrusion 220 can no longer be moved to the second through-hole S2-2 by the protrusion such as burr.

In order to prevent this, the height direction width of the cutting space S3 is formed to be larger than the height direction width of the ground protrusion 220, that is, the cutting space S3 is formed in the height direction, So that the ground protruding portion 220 does not overlap the edge of the connecting recess portion 140 and / or the edge portion of the ground main body portion 210, So that it can be sufficiently moved onto the second through-hole S2-2.

As a result, the fixing between the grounding device 200 and the connecting device 100 can be further strengthened.

In addition, for example, the ground main body 210 may form the fixing hole H5 into which the connection insertion portion 150 is inserted.

For example, the fixing hole H5 may be formed below the ground protrusion 220, and the connection insertion portion 150 may be located below the second through-hole S2-2.

Therefore, when the ground protrusion 220 is located on the first through-hole S2-1, the fixing hole H5 and the connection insertion portion 150 are spaced apart from each other, and the ground protrusion 220 The connection insertion portion 150 may be inserted into the fixing hole H5 when the connection insertion portion 150 is moved from the first through-hole S2-1 to the second through-hole S2-2.

For example, when the grounding protrusion 220 is located on the first through-hole S2-1, the grounding main body 210 may be spaced apart from the connection inserting unit 150, When the grounding protrusion 220 is moved downward from the first through-hole S2-1 and is moved to the second through-hole S2-2, the grounding main body 210 is connected to the connection insertion portion 150 and elastically deformed in the inner direction. When the ground protrusion 220 is further moved downward, the connection insertion portion 150 is inserted into the fixing hole H5, and at the same time, The ground main body 210 can be deformed elastically.

For example, when the connection inserting unit 150 is inserted into the fixing hole H5, the grounding unit 200 is connected to the connection inserting unit 150 by the contact between the grounding unit 210 and the connection inserting unit 150, The device 100 can be kept fixed.

As a result, even if an unintended external force is applied, the grounding apparatus 200 can be easily fixed to the connecting apparatus 100.

In addition, for example, the ground main body 210 may form a ground fastening hole H6 through which the fastening member can be fastened.

Hereinafter, the assembling process of the cable tray will be described.

As shown in FIG. 6, the operator can fix the grounding device 200 to the connecting device 100.

6A, the grounding protrusion 220 is allowed to pass through the first through-hole S2-1. Thereafter, as shown in Fig. 6B, The ground protrusion 220 can be disposed on the second through-hole S2-2.

As a result, the grounding apparatus 200 can be fixed to the connecting apparatus 100. [

Then, as shown in Fig. 7, the operator can fix the connecting device 100 to the side rail R adjacent to the longitudinal direction.

7 (a), the operator may cause the connection coupling portion 160 to pass through the connection hole H1, and then, as shown in Fig. 7 (b) So that the connection main body 110 and the connection coupling 160 can surround the side rail R. [

As a result, the connecting device 100 can be fixed to the side rail R. [

Thereafter, the operator can firmly fix the connection device 100 and the side rail R using the engagement member.

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.
