Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable protection pipe,

The present invention relates to a cable shield and a cable protection pipe having the same.

BACKGROUND ART Generally, a cable through which electric power is transmitted or a cable through which an electric signal is transmitted is widely used in the modern society. The cable is embedded in the ground, underground, or the sea floor to provide electric or electric signals to a user. Therefore, without using the above-mentioned cables, it is not possible to operate various devices used in homes, factories, and the like.

However, the cable or the like emits an electromagnetic wave or the like toward the outside by electric or electrical signals moving along the inside thereof. It is important to prevent electromagnetic waves from leaking because these electromagnetic waves can have a bad influence on people including human being. In addition, when the cable is deteriorated or damaged due to environmental factors, it is difficult to efficiently transmit electrical signals along the cable. As a result, when a cable is installed, it is necessary to provide a means for shielding an electromagnetic wave or the like while protecting an internal cable. Although a lot of the protection means have been developed, the conventional protection means is configured to be used semi-permanently once it is buried or installed. Therefore, when maintenance is required due to a failure in a cable or the like, there is an inconvenience that the protection means is disassembled or disassembled to repair the cable, and the protection means must be installed again. This increases the maintenance cost of the cable and furthermore, it takes a lot of time, which makes maintenance of the cable difficult.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cable protector capable of effectively shielding electromagnetic waves and the like which may occur in a cable in order to solve the above problems. Particularly, the present invention provides a cable shield which can access the cable without breaking the protection hole when maintenance of the cable is required, and can shield and protect the cable again when maintenance of the cable is completed . As a result, the present invention aims at providing a cable shield which can be used for a long period of time while maintaining or improving accessibility to the cable.

The above and other objects can be accomplished by the provision of a connector comprising: a base portion having a predetermined length for receiving a cable; a cover portion connected to selectively open and close the base portion to provide a space between the base portion and the cable; And a shielding portion provided on at least one of the cover portions so as to surround at least a part of the cable. Here, the base portion and the cover portion may be formed in an arc shape having a predetermined radius.

Meanwhile, the cover unit may include at least one cover rotatably connected to the base unit. For example, the cover portion may include a first cover rotatably connected to the base portion.

The first cover may include a first coupling portion at one end and a first coupling portion at the other end, and one end of the base may include a second coupling portion selectively coupled to the first coupling portion. Here, the first engaging portion and the second engaging portion may have the shape of a concave-convex portion corresponding to each other. The first cover may include at least one of the first end and the second end of the first cover.

The shielding portion may include a first shielding film provided on the first cover and a second shielding film provided on the base portion, and the first shielding film and the second shielding film may be overlapped at least partially. Specifically, the first shielding film extends toward the first engaging portion and the second shielding film extends toward the second engaging portion, and when the first engaging portion and the second engaging portion are connected, At least a part of the second shielding film may overlap.

In another embodiment, the cover portion may include a second cover rotatably connected to the base portion, and a third cover rotatably connected to the base portion and selectively connected to the second cover. For example, the second cover may have a second rotation axis at one end and a third engagement portion at the other end, wherein one end of the third cover has a third rotation axis and the third engagement And a fourth coupling portion selectively coupled to the second coupling portion. Here, the third engaging portion and the fourth engaging portion may have a shape of a concave-convex portion corresponding to each other.

The shielding portion may include a third shielding film provided on the second cover and a fourth shielding film provided on the third cover, and the third shielding film and the fourth shielding film may be overlapped at least partially. The third shielding film extends toward the third coupling portion and the fourth shielding film extends toward the fourth coupling portion, and when the third coupling portion and the fourth coupling portion are connected, the third shielding film and the fourth shielding film, At least some of which may overlap. Furthermore, it is also possible to provide means for preventing foreign matter from entering at least one of both ends of the second cover and both ends of the third cover.

The above-described object of the present invention can be achieved by a cable protection pipe in which two or more of the above-described cable protective members are connected. Here, the two or more cable shields may be detachably connected to each other.

According to the cable shield of the present invention having the above-described structure, it is possible to effectively shield electromagnetic waves and the like, which may occur in the cable, and further to protect the cable. In particular, when the maintenance of the cable is required, the cover portion can be simply opened without damaging the protective member to ensure accessibility to the cable. Further, when the maintenance of the cable is completed, the cover portion can be closed again to again shield and protect the cable. As a result, the cable shield of the present invention offers the advantage of being able to be used for a long time while maintaining or improving accessibility to the cable.

Hereinafter, various embodiments of the present invention will be described in detail with reference to the drawings.

1 is a perspective view illustrating a cable protector 100 according to an embodiment of the present invention.

Referring to FIG. 1, the cable protector 100 includes a base portion 110 and a base portion 110 to provide a space through which the cable 1 is inserted between the base portion 110 and the base portion 110, And a cover portion connected to selectively open and close the cover 110. The cable protector 100 may further include a shielding portion provided on at least one of the base portion 110 and the cover portion to surround at least a part of the cable 1. [

The base portion 110 provides a space in which at least one cable 1 can be seated, and in the embodiment according to FIG. 1, the base portion 110 is provided to provide a space through which the cable 1 passes . The base 110 may have a predetermined strength so as to protect the cable 1 therein, and may be made of a synthetic resin or the like to facilitate fabrication. In addition, although the base portion 110 has a substantially cylindrical shape with both ends open in Fig. 1, the present invention is not limited thereto. That is, the base portion 110 may have any shape, for example, a rectangular shape, which can provide a space through which the cable 1 can pass. In this embodiment, the base portion 110 may have a curved shape, or may have an arc shape having a predetermined radius as shown in the figure. Further, the base portion 110 may be made to have a predetermined length to facilitate transportation. If the length of the base portion 110 is too long, it may be inconvenient to carry. Conversely, if the length of the base portion 110 is too short, a considerably large number of protector may be required in case of cable embedding or the like, . Thus, the base portion 110 may have a length of, for example, about 10 m to 15 m for convenience of transportation.

Meanwhile, the cable protector 100 may have a cover portion for selectively opening and closing the base portion 110 to provide a space through which the cable 1 passes, as described above. The cover portion may be made of the same material as the base portion 110 described above.

The cover portion can be opened manually or automatically by an operator. Therefore, even when the cable 1 is positioned inside the cable protection hole 100 and the cable protection hole 100 is buried in the ground or the like, the operator can easily open the cover 1) can be repaired. As a result, the cable protector 100 according to the present embodiment improves the accessibility of the cable 1, and in particular, the cable protector 100 can be approached to the cable 1 and maintained without any breakage or the like . Therefore, after the worker completes maintenance on the cable 1, it becomes possible to use the cable protector 100 again by closing the cover portion. When the cover portion is closed, the base portion 110 and the cover portion have a cylindrical shape with both ends opened as shown in FIG. 1, and the cable 1 is inserted into the internal space.

The cover portion may include at least one cover 130 rotatably connected to the base portion 110. Here, the number of the cover 130 constituting the cover portion can be appropriately adjusted. However, as the number of the cover 130 increases, the operator may feel inconvenience to open the cover 130, and the configuration of the cover portion may become complicated. Therefore, in the following, it is assumed that the number of the covers 130 constituting the cover portion is one or two. However, the present invention is not limited to this, and the number of the cover 130 constituting the cover portion may be three or more.

For example, the cover portion may include a first cover 130 that is pivotally connected to the base portion 110. Fig. 2 shows a state in which the first cover 130 forming the cover part is opened in Fig.

Referring to FIG. 2, the base 110 may have an opening 118 connected to the outside at one side thereof while providing a space in which the cable 1 can be seated. The first cover 130, May be provided adjacent to the opening 118. Specifically, the first cover 130 may be provided to selectively open or close the opening 118. The first cover 130 may be formed in various forms to open and close the opening 118. For example, although not shown in the drawings, the first cover 130 may be provided in a form slidable along the base portion 110. In this embodiment, the first cover 130 is rotatably mounted on the base 110 to open and close the opening 118.

Meanwhile, in the cable protector 100 according to the present invention, the cable 1 or the like is seated in the ground, or located on the ground or in the ground. In this case, it is necessary to shield the electromagnetic wave or the like generated in the cable 1 from leaking out of the cable protector 100. For this purpose, the cable protector 100 may include a shielding portion provided on at least one of the base portion 110 and the cover portion to surround at least a part of the cable 1. [

The shield may be provided to surround at least a part of the cable 1 in order to prevent electromagnetic waves or the like which may be generated in the cable 1 provided in the cable protector 100 from leaking to the outside.

Fig. 3 is a side sectional view of Fig. 1, showing the configuration of the shielding portion. Fig.

3, the shielding portion of the cable protector 100 according to the present embodiment includes a first shielding film 132 provided on the first cover 130 and a second shielding film 112 provided on the base 110. [ . The first shielding film 132 and the second shielding film 112 are provided inside the first cover 130 and the base 110, respectively. For example, when the first cover 130 or the base 110 is fabricated by injection molding or the like, the first shielding film 132 and the second shielding film 112 are disposed, The first cover 130 or the base 110 can be manufactured.

The material of the shield can be varied. For example, the shield may be made of a ferromagnetic material, such as silicon, or may be made of a material such as aluminum. In the case of using a ferromagnetic material, the shielding effect can be enhanced even with a relatively thin thickness. However, since the cable shield 100 must be completely surrounded, there is a disadvantage in heat dissipation inside the shield. On the other hand, although aluminum can be made relatively thick, it has an advantage over the ferromagnetic material in heat dispersion and the like. In the present embodiment, a shielding film made of aluminum is used in the case of constructing the shielding portion, but the present invention is not limited to this.

Meanwhile, as described above, the cable protector 100 has a cover portion so as to be accessible to the inside of the base portion 110. However, it is convenient for the operator to work on the upper portion of the cable protector 100 when the operator carries out the maintenance of the cable 1. [ That is, the cover portion is preferably formed on the upper portion of the base portion 110. Accordingly, the second shielding film 112 provided on the base 110 can be separated into two shielding films around the cover (or the opening 118). That is, as shown in the figure, the second shielding film 112 may include a first separation shielding film 112A and a second separation shielding film 112B provided along the base 110. [ In addition, the first cover 130 is provided with the first shielding film 132.

Therefore, the first shielding film 132 and the second shielding film 112 are formed on the cable 1 so that the electromagnetic wave or the like, which may be generated in the cable 1, (Hereinafter referred to as a "shielding angle")? 1. The shielding angle? 1 can be appropriately adjusted. For example, if the cable protector 100 according to the present invention is installed on the ground, it is preferable that electromagnetic waves do not leak from the center of the cable protector 100 toward all directions. In this case, the shielding angle? 1 surrounding the cable 1 by the first shielding film 132 and the second shielding film 112 may be 360 degrees. That is, the first shielding film 132 and the second shielding film 112 shield all directions along the periphery of the cable 1, so that leakage of electromagnetic waves and the like from the cable shield 100 can be prevented as much as possible. In this structure, the first and second separation shielding films 112A and 112B may be connected to each other to form a single shielding film. That is, when the shielding angle? 1 is 360 degrees, the second shielding film 112 provided on the base 110 is formed as one member, and the base 110 is formed inside the base 110 As shown in FIG.

On the other hand, when the cable protector 100 according to the present embodiment is embedded in the ground, the shielding angle? 1 may be smaller than 360 degrees. That is, if the cable protector 100 is buried in the ground, it is necessary to prevent the electromagnetic wave from leaking to the ground, but it is not necessary to shield the electromagnetic wave leaking from the cable protector 100 to the ground. This can result in cost reduction and the like when the cable protector 100 is manufactured. In other words, if the shielding portion is formed at a predetermined angle rather than covering the entire length (360 degrees) of the cable protector 100, it is possible to reduce the material of the shielding portion, have. Therefore, when the cable protective member 100 is buried in the ground, the shielding angle? 1 can be set to about 180 degrees or more. Specifically, the shielding angle? 1 can be set to 240 degrees or more.

However, when the shielding angle? 1 is smaller than 360 degrees, the position of the region surrounded by the shielding portion is important. For example, if the area surrounded by the shield is directed to the ground, the shield is not enclosed and the open area is directed toward the ground, thereby reducing the effectiveness of shielding. Therefore, when the shielding angle? 1 is smaller than 360 degrees as shown in FIG. 3, shielding is formed at the same angle from both ends of the imaginary line? Extending from the center of the cable protector 100 and perpendicular to the ground desirable. That is, the sum of the first shielding angle? 2 formed on the left side of the imaginary line? And the second shielding angle 2 formed on the right side is equal to the sum of the shielding angles? 1 described above.

Meanwhile, the cable protector 100 according to the present embodiment is provided with a cover portion for the convenience of the operator and for extending the service life of the cable protector 100. [ However, since the cover portion is selectively opened and closed, it is necessary to prevent the electromagnetic wave or the like from leaking to the outside when the cover portion and the base portion 110 are connected. To this end, the cable protector 100 may be provided so that at least a part of the first shielding film 132 and the second shielding film 112 are overlapped. That is, the first shielding film 132 provided on the cover part and the second shielding film 112 provided on the base part 110 may be provided so that at least a part thereof overlaps when the cover part is closed (when the cover part is closed). This will be described later in detail with reference to the drawings. Hereinafter, the configuration of the cover portion will be described in more detail.

FIG. 4 is an enlarged view of the 'A' region in FIG. 3, and FIG. 5 is an enlarged view of the 'B' region in FIG.

4 shows the engagement of the first cover 130 and the base portion 110. Fig. For example, the first cover 130 may include a first engaging portion 140 at the other end, and a second engaging portion 140 at one end of the base portion 110, (120). The first engaging part 140 of the first cover 130 and the second engaging part 120 of the base part 110 are detachably connected. This is because it is necessary to seal the inside of the cable protector 100 while enhancing the accessibility of the operator's cable (1). Specifically, the first engaging portion 140 and the second engaging portion 120 may be formed to have a shape of a concave-convex portion corresponding to each other.

Further, it is possible to provide a coupling means for increasing the coupling force when the first coupling portion 140 and the second coupling portion 120 are connected. The coupling means may be provided in various forms, and in the present embodiment, fastening means such as bolts are provided to provide a coupling force. That is, in this embodiment, the first engaging portion 140 is provided with a through hole 134 through which a bolt or the like passes, and the second engaging portion 120 is provided with a fastening hole 116 corresponding to the through hole 134 Respectively. When the open portion 118 of the cable protector 100 is closed, the operator closes the first cover 130 and presses the first engaging portion 140 and the second engaging portion 120 with the bolts 190 or the like So that the first cover 130 can be closed.

The first shielding film 132 and the second shielding film 112 may be formed in the case where the cover portion is closed or the first and second coupling portions 140 and 120 are connected as described above. May be configured to overlap at least a part.

For example, the first shielding film 132 may extend toward the first coupling portion 140 and the second shielding film 112 may extend toward the second coupling portion 120. That is, the first shielding film 132 may extend toward the protrusion of the first coupling part 140 and the second shielding film 112 may extend toward the protrusion of the second coupling part 120. Since the first engaging portion 140 and the second engaging portion 120 have a shape corresponding to each other, the projecting portion of the first engaging portion 140 extends toward the second engaging portion 120, The protrusion of the second coupling portion 120 extends toward the first coupling portion 140. Therefore, the projecting portion of the first engaging portion 140 and the projecting portion of the second engaging portion 120 are configured to overlap with each other. The first shielding film 132 extends toward the protrusion of the second coupling portion 120 and the second shielding film 112 extends toward the protrusion of the first coupling portion 140 so that the first shielding film 132 And the second shielding film 112 may overlap with each other by a predetermined length. 3, the first shielding film 132 and the second shielding film 112 are overlapped by a predetermined length L1. The overlapping length of the shielding film (hereinafter referred to as the overlap length) can be appropriately adjusted. For example, if the overlap length is relatively long, the shielding effect of the electromagnetic wave increases, but the production cost may increase. On the other hand, if the overlap length is relatively short, the production cost can be reduced but the shielding effect can be relatively reduced. Therefore, the overlap length can be determined in consideration of various factors such as the size of the cable protector 100 and the number of cables 1 accommodated therein.

Meanwhile, since the cover portion is configured to be openable and closable to the base portion 110, foreign matter can flow into the space along the gap between the cover portion and the base portion 110. Such foreign matter inflow may cause deterioration of the performance of the cable 1 located inside the cable protector 100, and may further cause breakage of the cable 1. [ Therefore, the cable protector 100 may include a preventing means for preventing foreign matter from flowing along the gap between the cover portion and the base portion 110.

For example, the prevention means may be provided on at least one of the first end and the second end of the first cover 130. The prevention means may be provided between the first engagement portion 140 of the first cover 130 and the second engagement portion 120 of the base portion 110. In this case, the preventing means may include a first preventing portion 180 provided on at least one of the first engaging portion 140 and the second engaging portion 120. The prevention part 180 may be provided along a region where the first engaging part 140 and the second engaging part 120 are engaged. Therefore, it is possible to prevent foreign matter or the like from penetrating along the gap between the first engaging part 140 and the second engaging part 120. The first prevention part 1800 may be made of a material such as rubber, thereby preventing the penetration of foreign matter and moisture.

Referring to FIG. 5, the first cover 130 may include a first pivot shaft 170 at one end 145 thereof. The first coaxial shaft 170 is connected to one end 145 of the first cover 130 and rotates the other end 125 of the base 110 and one end 145 of the first cover 130 Possibly connect. The one end 145 of the first cover 130 may be rounded to prevent the one end 145 of the first cover 130 from interfering with the base 110 when the first cover 130 rotates. Lt; / RTI > A second prevention part 182 may be provided between one end 145 of the first cover 130 and the other end 125 of the base part 110 to prevent foreign matter from entering as described above. The first shielding film 132 and the second separation shielding film 112B may be formed to have a predetermined overlap length L2 in order to prevent leakage of electromagnetic waves and the like that may occur in the cable 1 provided therein. have. To this end, one end 145 of the first cover 130 and the other end 125 of the base 110 may have a concavo-convex shape corresponding to each other.

The cable protector 100 according to the above-described embodiment has been described on the assumption that the cable protector 100 has an opening portion at one side of the base portion 110 and includes a cover for opening and closing the opening portion. In this case, since the inside of the cable protector 100 can be accessed through the opening, the path for accessing the interior of the cable protector 100 is limited. In some cases, however, it may be necessary to work with the inside of the cable protector 100 fully open. Therefore, an example in which the number of covers constituting the cover portion is two or more will be described below.

FIG. 6 is a perspective view showing a cable shield according to another embodiment of the present invention, and FIG. 7 shows a state in which the cover is opened in FIG. The cable protector 100 of the present embodiment is different from the above-described embodiment in that it has two covers constituting the cover portion. Hereinafter, descriptions similar to those of the above-described embodiments will be omitted because they are duplicated, and differences will be mainly described.

6 and 7, the cable protector 200 is provided to provide a space through which the cable 1 passes between the base portion 210 and the base portion 210 of a predetermined length at which the cable 1 is seated And a cover portion connected to selectively open and close the base portion 210. [ The cable protector 200 may further include a shielding portion provided on at least one of the base portion 210 and the cover portion to surround at least a part of the cable 1. [

The base portion 210 may provide a space in which at least one cable 1 can be seated. In this case, the base portion 210 may be provided with a flat plate in a curved shape, or may be provided in an arc shape along a predetermined radius. That is, in the embodiment according to the above-described FIG. 1, the base portion 110 is formed in a substantially cylindrical shape and has an opening at one side. However, since two covers are provided in this embodiment, the base portion 210 may have a curved shape, rather than a cylindrical shape, as the area occupied by the cover increases. Of course, even if two covers are provided, if the width of the cover is reduced, the base portion can have a substantially cylindrical shape.

Meanwhile, the cover portion may have two or more covers, for example, two covers in this embodiment. Specifically, the cover portion includes a second cover 240 rotatably connected to the base portion 210, a third cover 240 rotatably connected to the base portion 210 and selectively connected to the second cover 240 260 may be provided. 7 shows a state in which the second cover 240 and the third cover 260 are opened and the inside of the cable protector 200 is completely opened. As shown in FIG. 7, when the second cover 240 and the third cover 260 are opened, the cable accessibility can be remarkably improved as compared with the case where the second cover 240 and the third cover 260 are simply accessed through the opening portion. Therefore, the workability can be remarkably increased when the worker performs work such as maintenance of the cable.

7, the second cover 240 may be rotatably connected to one end of the base 210, and the third cover 260 may be rotatably connected to the other end of the base 210 Can be connected. The second cover 240 and the third cover 260 may be connected to each other. As a result, when the second cover 240 and the third cover 260 are connected to each other and closed, the base 210, the second cover 240, and the third cover 260, It is possible to have the shape of a circular cylinder opened.

In this case, the second cover 240 and the third cover 260 may be configured to have the same area (or the same width) as shown in the drawing. However, the present invention is not limited thereto, and it is of course possible that the second cover and the third cover have different areas (or widths).

Meanwhile, the cable protector 200 may have a shielding portion that shields electromagnetic waves generated from the cable 1 from leaking out of the cable protector 200. The shield may be provided to surround at least a part of the cable 1 in order to prevent an electromagnetic wave or the like, which may be generated in the cable 1 provided in the cable protector 200, from leaking to the outside.

Fig. 8 is a side sectional view of Fig. 6 showing the configuration of the shielding portion. Fig.

8, the shielding portion of the cable protector 200 includes a third shielding film 245 provided on the second cover 240 and a fourth shielding film 265 provided on the third cover 260, The third shielding film 245 and the fourth shielding film 265 may be provided so as to overlap at least a part thereof. Although only the second cover 240 and the third cover 260 are shown with the shielding film in FIG. 8, the present invention is not limited thereto. It is of course possible to provide an additional shielding film in the base 210. In this embodiment, a shielding film made of aluminum can be used as in the above-described embodiment. Since this has been described in the above-described embodiment, repetitive description will be omitted.

The angle of shielding by the shielding film may be set to about 180 degrees or more, more specifically 240 degrees or more, in the same manner as in the above embodiment. However, when the shielding angle is smaller than 360 degrees, the position of the region surrounded by the shielding portion is important as described above. The shielding portion includes a third shielding film 245 and a fourth shielding film 265 provided in the second cover 240 and the third cover 260, respectively. Therefore, when the second cover 240 and the third cover 260 have the same area (or width), the engaging portion of the second cover 240 and the third cover 260 substantially coincides with the center of the cable protector 200 And is configured to coincide with an imaginary line? Perpendicular to the paper surface. In this case, the sum of the third shielding angle? 5 by the third shielding film 245 and the fourth shielding angle? 6 by the fourth shielding film 265 becomes equal to the desired shielding angle? 4.

When the areas (or widths) of the second cover 240 and the third cover 260 are different from each other, regardless of the position of the coupling portion of the second cover 240 and the third cover 260, Shielding can be formed at the same angle from both sides of the imaginary line? That meets vertically with the ground.

Further, in the case where the shielding film completely covers the circumference of the cable 1 (when the shielding angle is 360 degrees), an additional shielding film may be provided in the base portion 210 as well. Further, even when the shielding angle is less than 360 degrees, an additional shielding film may be provided in the base portion 210 for effective shielding.

Also, in the cable protector 200 according to the present embodiment, at least a part of the third shielding film 245 and the fourth shielding film 265 may be overlapped. That is, the third shielding film 245 and the fourth shielding film 265 may be provided so that at least a part of the third shielding film 245 overlaps (when the cover is closed). This will be described later in detail with reference to the drawings. Hereinafter, the configuration of the cover portion will be described in more detail.

FIG. 9 is an enlarged view of the 'C' area in FIG. 8, and FIG. 10 is an enlarged view of the 'D' area in FIG.

Fig. 9 shows the engagement of the second cover 240 and the third cover 260.

For example, the third shielding film 245 may extend toward the third coupling portion 247 and the fourth shielding film 265 may extend toward the fourth coupling portion 267. That is, the third shielding film 245 extends toward the protrusion of the third coupling portion 247, and the fourth shielding film 265 may extend toward the protrusion of the fourth coupling portion 267. Since the third engaging portion 247 and the fourth engaging portion 267 have a shape corresponding to each other, the projecting portion of the third engaging portion 247 extends toward the fourth engaging portion 267, The projecting portion of the fourth engaging portion 267 extends toward the third engaging portion 247. Therefore, the projecting portion of the third engaging portion 247 and the projecting portion of the fourth engaging portion 267 are configured to overlap with each other. The third shielding film 245 extends toward the protrusion of the third coupling portion 247 and the fourth shielding film 265 extends toward the protrusion of the fourth coupling portion 267 so that the third shielding film 245 And the fourth shielding film 265 may be overlapped with each other by a predetermined length. In FIG. 9, the overlap length of the third shielding film and the fourth shielding film is configured to overlap by a predetermined length L3. The overlap length can be appropriately adjusted and the overlap length can be determined in consideration of various factors such as the size of the cable protector 200 and the number of cables 1 accommodated therein.

Meanwhile, it is possible to prevent foreign matter from flowing along the gap between the cover part and the base part 210. The prevention means may be provided on at least one of both ends of the second cover 240 and both ends of the third cover 260. The preventing means may be provided between the third engaging portion 247 of the second cover 240 and the fourth engaging portion 267 of the third cover 260. In this case, the preventing means may include a third preventing portion 280 provided in at least one of the third engaging portion 247 and the fourth engaging portion 267. The prevention part 280 may be made of a material such as rubber, thereby preventing foreign matter and moisture from penetrating.

Referring to FIG. 10, the third cover 260 includes a third rotation shaft 225 at one end thereof and the second cover 240 may have a second rotation shaft (not shown) at one end thereof. have. In FIG. 10, only the rotating shaft 225 of the third cover 260 is shown in order to prevent duplication of description, and the structure of the second cover is symmetrical with the structure of the third cover, and therefore, repetitive description will be omitted.

The third coaxial shaft 225 is connected to one end of the third cover 260 and rotatably connects one end of the third cover 260 with the base 210. The end of the third cover 260 may be rounded to prevent one end of the third cover 260 from interfering with the base portion 210 when the third cover 260 rotates. Also, a fourth prevention part 220 may be provided between the end of the third cover 260 and the base part 210 to prevent foreign matter from entering as described above.

Meanwhile, the cable protector 200 according to various embodiments described above may have a predetermined length to facilitate transportation. However, since the length of the cable 1 connecting the supplier and the consumer is relatively long, a cable protection pipe 1000 for protecting the cable 1 is required.

11 is a perspective view illustrating a cable protection pipe 1000 according to an embodiment.

Referring to FIG. 11, the cable protection pipe 1000 includes two or more cable protrusions 200, and the cable protector 200 is provided in parallel to the longitudinal direction. In this case, the cable protector 200 may be simply tangent or may be removably connected to each other without a separate coupling means. For example, each cable protector 200 may have a connection portion (not shown) connected to another cable protector 200 at least at one of both ends. The connection portion may be variously embodied and may be provided with a connection portion having a fastening means such as a bolt.

As a result, it is possible to manufacture the cable protection pipe 1000 having a predetermined length or longer by connecting two or more cable protectors 200 to each other, thereby effectively shielding the electromagnetic wave, which may leak from the cable 1, can do.

11 shows a cable protection pipe 1000 having a cable protection 200 according to the embodiment of FIG. 6, but this is merely an example, and the cable protection 200 according to FIG. 1, It is of course possible to provide a cable shield according to the embodiment.
