The present invention also relates to a through-hole system for leading a cable or pipe through a partition, the through-hole system comprising the through-hole device.
Background Art
[0003] Penetration devices and systems are used to conduct cables and pipes through partitions such as walls, floors, and ceilings. Penetration devices are used in many different environments, including cabinets, junction boxes, and machinery, as well as in different industrial applications such as automotive and freight vehicle applications, communications, power generation and distribution, and marine and offshore applications. Depending on the application, penetration systems are often required to have a sealing function, such as sealing against different types of liquids such as water and / or gases such as air. To provide fastening and / or sealing functions, cables or pipes are generally placed in a penetration opening of a compressible module. One common type of such module comprises two opposing module halves arranged around the cable or pipe, and the module is placed in a frame positioned in the opening of the partition. The module in the frame is then compressed by a compression unit, pressing the module against the inner surface of the frame, against each other where applicable, and against the cable or pipe within the module, fastening the module and cable or pipe and sealing the penetration. The penetration system may be arranged to be airtight against liquids such as water, gas, fire, rodents, termites, dust, and moisture. The penetration system and modules may be arranged to receive, for example, cables for electricity, communications, computers, etc., or pipes for different gases or liquids such as water, compressed air, hydraulic fluids, and cooking gases.
[0004] One of the problems with conventional penetration devices and systems is that they are difficult and expensive to manufacture.
[0005] Another problem with prior art penetration devices and systems is that they are difficult to install and sometimes difficult to use.
[0006] Another problem with some types of conventional penetration devices is that they can be unreliable. [Overview of the project]
[0007] In view of the above, one object of the present invention is to provide a robust penetration device and system that can be manufactured and installed in an easy and efficient manner to provide a reliable penetration for cables or pipes.
[0008] The present invention relates to a penetration device for conducting cables or pipes through a partition. The penetration device comprises a frame, a compression unit, and a compression screw for operating the compression unit. The frame comprises first, second, third, and fourth interconnected walls surrounding an opening. The compression unit is positioned in the opening of the frame and is operable to compress one or more compressible modules positioned in the opening of the frame. The compression screw extends through the opening in the first wall of the frame. The through-hole device is characterized in that the frame comprises a guide surface positioned between the second and fourth walls and perpendicular to the first wall, the guide surface engaging with a first side of the compression unit to guide the compression unit when actuated by a compression screw, and the through-hole device further comprises an angle element having a first plate portion and a second plate portion positioned perpendicular to the first plate portion, the first plate portion being positioned within an opening in the frame and parallel to the first wall and having a through hole for a compression screw, and the second plate portion engaging with a second side of the compression unit opposite its first side to guide the compression unit when actuated by a compression screw.
[0009] The angled elements of the penetration device provide a robust and reliable penetration for cables or pipes while facilitating manufacturing and installation. The combination of the frame's guide surface and the angled elements results in a solid and reliable penetration, while the frame can be cast in a simple and cost-effective manufacturing process. Since the angled elements can be manufactured separately, the frame can be cast as a single piece using a simple casting mold. For example, a frame with a guide surface can be cast as a single integrated piece, and then the frame can be assembled with the angled elements, providing simplified manufacturing and easy assembly. The present invention also allows the frame and angled elements to be formed from different materials.
[0010] The through-holes in the first plate portion may be formed with threads that cooperate with the threads of the compression screw. Thus, the angle element is provided with threads, and the load from the compression screw is transmitted to the angle element instead of, or in addition to, transmitting the load to the threads of the frame. This makes it possible to form the frame from a material that does not provide strong threads. For example, the frame can be formed from aluminum or a composite material. In addition, the frame can be formed without any threads, which simplifies manufacturing. For example, the angle element can be formed from a material that provides strong threads, such as steel. This provides a robust and durable through-hole device. Alternatively, threads for cooperating with the compression screw can be formed on both the frame and the angle element.
[0011] The second plate portion may be positioned perpendicular to the second and fourth walls and may engage with them. Thus, the angle element is prevented from rotating in the corresponding direction during the operation of the compression screw, which provides a more robust and reliable penetration device.
[0012] The angle element is a single, integrated component separate from the frame, and can be formed from, for example, metal, which provides a cost-effective and strong structure that is easy to manufacture.
[0013] The second plate portion may include wings that are received in corresponding recesses in the second and fourth walls of the frame, so as to prevent movement of the angular element in a direction perpendicular to the plane of the first plate portion. Thus, a more reliable structure is achieved. The wings may also project into the plane of the second plate portion, which may facilitate the manufacture of the angular element and the manufacture of the frame.
[0014] The compression screw can be positioned to rotate relative to the compression unit, thereby facilitating the operation and durability of the penetration device. The compression unit is rotatably mounted to the compression screw and is displaceable along its longitudinal direction with the compression screw in both the direction for compression and the direction for decompression. Thus, decompression is more efficient and reliable.
[0015] The present invention also relates to the use of such penetration devices for conducting cables or pipes through partitions.
[0016] Furthermore, relating to a penetration system for conducting cables or pipes through a partition, the penetration system comprises the penetration device described in claims 1 to 16 and one or more compressible modules arranged within a frame, wherein the compression unit engages with at least one of the compressible modules, and the cable or pipe is placed in at least one penetration opening of the compressible module.
[0017] Further objectives and advantages of the present invention will become apparent to those skilled in the art upon reading the following detailed description. [Brief explanation of the drawing]

[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Referring to Figures 1 and 2, a transit device 10 for passing at least one cable 11 and / or at least one pipe through a partition 12 is schematically shown according to one embodiment. In Figure 2, a part of the partition 12 is shown by a dashed line. The transit device 10 is shown in the compressed position in Figures 1 and 2. A cross-sectional view of the transit device 10 in the compressed position is shown in Figures 3 and 4. The partition 12 is also schematically shown by a dashed line in Figure 3.
[0020] The penetration device 10 is arranged to pass one or more cables 11 and / or pipes through a partition 12. The partition 12 is in the form of, for example, a wall, floor, roof or ceiling. For example, the penetration system 10 is arranged to pass cables 11 such as cables for electricity, communication, computers, etc., or pipes for different gases or liquids such as water, compressed air, hydraulic fluid, cooking gas, or other types of liquids or gases, through the partition 12. The cable and / or pipe is conductively led axially through the penetration device 10. For example, the penetration device 10 is arranged in the penetration opening of the partition 12 and is attached to the partition 12 by fastening means such as screws, welded joints or the like.
[0021] The penetration device 10 shown in Figure 1 is arranged to receive one or more compressible sealing modules 13 for holding a cable 11 or pipe. The sealing modules in Figures 1 to 4 are shown with a portion of the cable 11 or pipe inside, and it is understood that the cable 11 or pipe follows. It is also understood that if the cable 11 or pipe is not located inside, a conventional blind plug 11a may be provided in the sealing module 13. The sealing modules 13 may be arranged in different sizes, and multiple different sealing modules 13 may be arranged in different configurations in the penetration device 10. The penetration device 10 in the illustrated embodiment has two sealing modules 13 of the same size, but it should be understood that any suitable number of sealing modules of the same or different sizes may be provided. The sealing modules 13 are compressible. For example, the sealing module 13 is elastic and comprises two opposing compressible bodies 14 in the form of a sealing module half, where the compressible bodies 14 are compressible sealing module halves. Optionally, each compressible body 14 comprises a plurality of peelable sheets 15 arranged in semi-cylindrical grooves within the compressible body 14. For example, each compressible body 14 has its own stack of semi-cylindrical peelable sheets 15. For example, the peelable sheets 15 are of a conventional type and are provided to fit the diameter of the groove to the outer diameter of the cable 11 or pipe. Optionally, a suitable number of peelable sheets 15 are removed to fit the sealing module 13 to the diameter of the cable 11 or pipe, and the cable 11 or pipe is placed inside the compressible body 14, and the sealing module 13 is formed by placing two module halves 14 on top of each other such that the grooves face each other and form an opening for the cable 11 or pipe. The compressible body 14 also has an outer surface. The sealing module 13 is elastic and is made of, for example, natural rubber, or synthetic rubber such as EPDM rubber with optional additional fillers, or TPE.
[0022] The penetration device 10 comprises a frame 16, a compression unit 17, and a compression screw 18 for operating the compression unit 17. The frame 16 comprises first, second, third, and fourth walls 19-22 that form an opening for receiving one or more sealed modules 13 and the compression unit 17. In the illustrated embodiment, the first and third walls 19, 21 are positioned opposite each other, and the second and fourth walls 20, 22 are positioned opposite each other and perpendicular to the first and third walls 19, 21. For example, the first wall 19 is the top wall of the frame 16, the second and fourth walls 20, 22 are the side walls, and the third wall is the bottom wall. The penetration device 10 can be mounted in an upright position where the first wall 19 extends in a horizontal plane, or in a reclining position where the first wall 19 extends in a vertical plane. For example, the frame 16 is substantially rectangular and optionally has rounded corners. For example, walls 19-22 are joined together end to end. For example, frame 16 is a cast frame, that is, formed as a single integrated part by die casting. According to one embodiment, frame 16 is made of a metal such as aluminum. Aluminum provides a lightweight penetration device that is easy to handle and install. Alternatively, frame 16 is made of steel. Alternatively, frame 16 is made of a composite material, which can also provide a lightweight penetration device that is easy to handle. According to one embodiment, frame 16 is made of a conductive material. In the illustrated embodiment, frame 16 includes a flange 23 for attachment to partition 12. Flange 23 is, for example, an outer circumferential flange surrounding the opening of frame 16. Optionally, flange 23 is formed with holes for fixing to partition 12 by screws or the like. In the illustrated embodiment, flange 23 is formed with grooves 24 for receiving a sealing strip (not shown) or the like for sealing against partition 12.
[0023] The first wall 19 of the frame 16 is formed with a through-opening 25 for the compression screw 18, and the compression screw 18 extends through the first wall 19 to operate the compression unit 17, such as to displace the compression unit 17 and / or to compress inside the opening of the frame 16. The through-opening 25 is shown in the exploded view of FIG. 5. For example, the compression screw 18 has one end outside the frame 16 and the opposite end in the opening of the frame 16, so that the compression unit 17 can be operated from the outside of the frame 16, for example via the screw head 26. According to an embodiment, the compression screw 18 can rotate freely within the through-opening 25. For example, the through-opening 25 (i.e., the frame 16 around the through-opening 25) is arranged without threads and may be, for example, smooth.
[0024] The frame 16 further comprises a guide surface 27 for guiding the compression unit 17. The guide surface 27 is arranged between the second and fourth walls 20, 22 and extends perpendicular to the first wall 19. For example, the guide surface 27 is formed as a plate portion having a plane that extends perpendicular to the first wall 19 and perpendicular to the second and third walls 20, 21, and covers a part of the opening of the frame 16, for example, the front part or the upper front part of the opening. The guide surface 27 is, for example, an integrated part of the frame 16. For example, the guide surface 27 is cast together with the rest of the frame 16. In the illustrated embodiment, the guide surface 27 is connected to the first wall 19 and the second and fourth walls 20, 22. The guide surface 27 is arranged to engage with the compression unit 17 and hold it in place within the opening of the frame 16. For example, the guide surface 27 is arranged to engage with the first side surface of the compression unit 17.
[0025] The compression unit 17 is configured to compress a compressible module 13 within an opening in the frame 16. For example, the compression unit comprises a compressible block 28, such as a block of rubber, TPE, or a similar elastic material. In the illustrated embodiment, the compression unit 17 also comprises a plate 29 made of a material more rigid than the compressible block 28, such as metal, to cooperate with the compression screw 18. The compressible unit 17 is compressible in the longitudinal direction of the compression screw 18, i.e., in the axial direction of the compression screw, and the compressible block 28 expands radially perpendicular to the longitudinal and axial directions of the compression screw 18. For example, the compression screw 18 engages with the top surface of the compression unit 17, and the opposing bottom surface of the compression unit 18 engages with one or more modules 13 directly or via a conventional stay plate or similar. For example, the compression unit 17 is displaceable in the longitudinal direction of the compression screw 18 in a direction perpendicular to the plane of the first wall 19. For example, the opposing sides of the compression unit 17 engage with the second and fourth walls 20, 22 of the frame 16. For example, the compressible block 28 is essentially a rectangular block.
[0026] For example, a compression screw 18 is fixed to a compression unit 17 in the axial direction of the compression screw 18, and the compression unit 17 is displaced together with the compression screw 18 in the longitudinal direction of the compression screw 18. In the illustrated embodiment, the compression screw 18 is attached to the compression unit 17 by an optional fastening device 30, and the compression screw 18 is rotatably attached to the compression unit 17 while the compression unit 17 is displaced within an opening in the frame. The compression unit 17 is displaceable together with the screw along the screw and along the second and fourth walls 20, 22, so that the compression unit can move toward and away from the first and second walls 19, 21. For example, the compression unit 17 is movable toward and away from the compressible module 13 by the compression screw. The attachment of the compression unit 17 to the compression screw 18 is particularly suitable for depressurizing the compression unit 17 and the compressible module 13, as the compression unit 17 is pulled away from the compressible module during depressurization.
[0027] According to one embodiment, the compression screw 18 is formed having a stem having a first stem portion 31 and a second stem portion 32 that form a shoulder for engaging with the plate 29 of the compression unit 17. For example, the second stem portion 32 has a smaller diameter than the first stem portion 31 and forms the shoulder. In the illustrated embodiment, the second stem portion 32 is the end of the compression screw 18, and the second stem portion 32 is positioned through an opening in the plate 29 and attached to the compression unit 17 via a fastening device 30. For example, the second stem portion 32 is attached to the fastening device 30 by cooperative threads. For example, the second stem portion 32 has a smooth outer surface, i.e., is positioned without threads. For example, the second stem portion 32 is formed having an axially threaded opening of the compression screw 18 to receive the fastening device 30, and the fastening device is positioned as a screw. Alternatively, the second stem portion 32 has a male thread that cooperates with the female thread of the fastening device 30, and the fastening device is formed as a threaded sleeve or nut. The compressible block 28 may be formed with an opening through which the fastening device 30 can be inserted to cooperate with the compression screw 18, and / or through which a portion of the compression screw 18 can extend to cooperate with the fastening device 30. The compression screw 18 is formed with threads for operating the compression unit 17 toward and away from the compressible module 13, so that the compression unit 17 can be compressed and pressed against the compressible module 13, and the compression unit 17 can be depressurized and / or moved away from the compressible module. For example, the first stem portion 31 is formed with a screw for moving the compression unit 17.
[0028] The penetration device further comprises an angled element 33. The angled element 33 is positioned to guide the compression unit 17. For example, the angled element 33 is made of a metal such as steel. The angled element 33 is not integrated with the frame 16. For example, the angled element 33 may be manufactured separately from the frame 16 and may be made of a different material than the frame 16. The angled element 33 and the frame 16 are assembled to form the penetration device 10. For example, the penetration device 10 can be disassembled and the angled element 33 can be optionally removed from the frame 16. The angled element 33 comprises a first plate portion 34 and a second plate portion 35 positioned perpendicular to the first plate portion 34. The first plate portion 34 is positioned, for example, in an opening in the frame 16 and is positioned parallel to the first wall 19 of the frame 16. Thus, the plane of the first plate portion 34 extends parallel to the plane of the first wall 19. The first plate portion 34 is provided with a through hole 36 for receiving a compression screw 18. The through hole 36 is shown in Figure 5. The hole 36 is aligned with a through opening 25 in the first wall 19 of the frame 16. The hole 36 is positioned with threads that cooperate with the compression screw 18 so as to allow the compression unit 17 to be compressed and decompressed. Thus, the first plate portion 34 is formed with threads around the hole 36. For example, the threads of the hole 36 cooperate with the threads of the compression screw 18 to displace the compression screw 18 in the longitudinal direction of the compression screw 18.
[0029] The second plate portion 35 engages with the second side of the compression unit 17 opposite its first side and guides the compression unit 17 when actuated by the compression screw 18. The second plate portion 35 has a plane that extends perpendicular to the plane of the first plate portion 34 and perpendicular to the planes of the second and fourth walls 20, 22. Thus, the through-device 10 comprises a guide surface 27 that covers the first portion of the opening in the frame 16 and a second plate portion 35 of the angle element that covers the second portion of the opening opposite the guide surface 27. Thus, the compression unit 17 is guided and held in place by the opposing second and fourth walls 20, 22 of the frame 16 together with the guide surface 27 and the second plate portion 35 of the angle element 33. Thus, the four sides around the compression unit 17, which connect the top and bottom surfaces of the compression unit, are at least partially engaged and guided by the frame 16 and the angle element 33 during the compression of the compression unit 17. For example, three sides of the compression unit 17 are at least partially in contact with the frame 16, and the remaining sides are at least partially in contact with the second plate portion of the angle element 33 during compression of the compression unit.
[0030] In the illustrated embodiment, the angle element 33 is provided with means to prevent its displacement along the second and fourth walls 20, 22 of the frame 16, i.e., to prevent displacement in the plane of the second plate portion 35. For example, the second plate portion 35 includes a wing 37 that cooperates with a recess in the frame 16 to prevent displacement of the angle element 33. In the illustrated embodiment, the wing 37 extends in the plane of the second plate portion 35 and is received in a corresponding recess in the frame 16, for example, in the opposing second and fourth walls 20, 22. The wing 37 and the corresponding recess prevent movement of the angle element 33 and ensure that the angle element 33 is maintained in place while the first plate portion 34 is in contact with the first wall 19 during both compression and decompression of the compressible module 13.
[0031] The through-hole device 10 is shown in the compression position in Figures 1-4, where the compression screw 18 is screwed inward toward the compressible module, displacing the plate 29 of the compression unit 17 in the same direction and compressing the compressible block 28 toward the compressible module 13. The threads of the compression screw 18 engage with the threads of the hole 36 of the angle element 33. Optionally, the threads of the compression screw 18 also engage with the threads of the through-opening in the first wall 19. Alternatively, the compression screw 18 rotates freely within the through-opening in the first wall 19. Thus, the compression screw 18 does not depend on the threads of the frame 16. Instead, the compression screw 18 works in cooperation with the threads of the angle element 33 to compress the compressible module 13. For example, as seen in Figures 3 and 4, the compression unit 17 is moved away from the first wall 19 toward the compressible module 13, and a portion of the compressible block 28 engages with the guide surface 27 and the angle element 33.
[0032] Referring to Figures 6-9, the through-hole device 10 is shown in the neutral or depressurized position before compression, and the compression screw 18 is loosened to decompress the compressible module 13. In the illustrated embodiment, the compression unit 17 is moved backward from the compressible module 13 by rotating the compression screw 18 in the opposite direction to its tightening and the opposite direction to the compression of the compressible module 13 by the compression unit 17. Thus, the compressible module 13 is compressed by tightening the compression screw 18 from the position shown in Figures 6-9 to the position shown in Figures 1-4. By tightening the compression screw 18, the compression unit 17 is compressed and / or moved toward the compressible module 13. For example, tightening the compression screw 18 displaces the compression screw 18 toward the compressible module, and the compression screw 18 displaces the plate 29 of the compression unit 17 in the same direction, which compresses the compressible block 28 relative to the compressible module 13 or displaces the compressible block 28 in a certain direction relative to the compressible module 13 so that the compressible module 13 is compressed. As shown in Figures 1 to 4, from the compressed position, the through-device 10 in the illustrated embodiment can be depressurized by loosening the compression screw 18, and the pressure on the compressible module 13 is released. In the illustrated embodiment, the compression unit 17 is retractable from the compressible module 13. The attachment of the compression unit 17 to the compression screw 18 is particularly suitable for depressurizing the compression unit 17 and the compressible module 13 because the compression unit 17 is pulled away from the compressible module during depressurization. According to one embodiment, the compression screw 18 is attached to the compression unit 17 by a fastening device 30 such as a fastening screw as shown.
[0033] As shown in Figures 6 to 9, in the retracted and depressurized positions, the compression unit 17 is displaced toward the first wall 19. For example, in the retracted position, the compression unit 17 is surrounded by the guide surface 27, the second plate portion 35 of the angle element 33, a portion of the second wall 20, and a portion of the fourth wall 22. For example, the compression unit 17 can be displaced until its plate 29 and other parts of the compression unit 17 come into contact with the first plate portion 34 of the angle element 33. In the neutral or depressurized position of the penetration device 10, the compressible module 13 and cable 11 can be attached to the opening of the frame 16. Next, the compression screw 18 can be tightened to compress the compression unit 17 toward the compressible module 13 as described above and as shown in Figures 1 to 4.
