Description

Technical Field

[0001] This utility model relates to the field of cable assembly technology, and more specifically, to a shrinkable multi-hole cable tray. Furthermore, it also relates to an electrical device comprising the aforementioned shrinkable multi-hole cable tray. Background Technology

[0002] In existing technologies, cable management boards are widely used in electronic and electrical equipment such as cabinets, junction boxes, and control boxes. They are used to fix, guide, and protect cables from scratches when passing through enclosure partitions, and also serve functions such as sealing, dustproofing, waterproofing, and electromagnetic shielding. The core requirement is to ensure a reliable seal between the cable management holes and the cables while accommodating different wire diameters.

[0003] However, most cable management boards on the market are currently tearable multi-layer conical cable management boards. These boards are typically made of flexible rubber or silicone and consist of multiple conical protrusions on a base. Each cone is pre-cut into multiple concentric rings (layers) of different diameters from top to bottom, each layer representing a wire diameter specification. Users can tear off the innermost ring of the desired diameter by hand or with a tool, creating a perforation of the required diameter. The cable is then passed through this perforation, and the material's elasticity causes the inner wall of the perforation to tightly wrap around the cable, achieving a seal.

[0004] However, due to the uncertainty of the pre-cut depth, material uniformity, and the angle and force of the user's tearing, the edges of the holes after tearing are prone to tearing, burrs, and unevenness (i.e., rough edges). Moreover, the rough and irregular edges after tearing cannot form a uniform and tight contact with the outer wall of the cable, creating tiny gaps that lead to seal failure. Moisture, dust, and other contaminants can then enter the equipment, causing risks such as short circuits and corrosion.

[0005] In summary, how to utilize the surface space of the threading plate, accommodate different wire diameters, and form a smooth, complete, and rounded sealing hole after operation to prevent product sealing failure due to improper operation is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a cold-shrink multi-hole wire threading board that can utilize the space of the support plate, accommodate different wire diameters, and form a smooth, complete, and rounded sealing hole after operation, thus eliminating the problem of product sealing failure caused by improper operation.

[0007] Another objective of this invention is to provide an electrical device comprising the aforementioned cold-shrink multi-hole wiring board.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A cold-shrink multi-hole cable tray, comprising:

[0010] A threading plate, comprising a support plate and at least one channel perpendicularly disposed on the support plate;

[0011] A cold-shrink support tube is pre-expanded and shaped and embedded in the channel. When the cable is not inserted into the channel, the cold-shrink support tube expands and seals the channel. When the cable is inserted into the channel, the cold-shrink support tube is pulled out and automatically shrinks.

[0012] A dust plug is provided at the port of the cold shrink support tube.

[0013] In one embodiment, the cold-shrink support tube comprises a polymer material component with shape memory effect.

[0014] In one embodiment, the support plate includes a rigid material component.

[0015] In one embodiment, the channel includes a resilient material element.

[0016] In one embodiment, the dust plug comprises a silicone material or a plastic material.

[0017] In one embodiment, the dust plug and the channel are threaded or snap-fitted together.

[0018] In one embodiment, one end of the dust plug is provided with two oppositely distributed handles, which are located away from the channel.

[0019] In one embodiment, the support plate is provided with an assembly portion.

[0020] In one embodiment, the support plate and the channel are an integral structure.

[0021] An electrical device comprising the cold-shrink multi-hole cable tray described in any of the preceding claims.

[0022] When using the cold-shrink multi-hole cable management board provided by this utility model, at least one channel vertically mounted on the support plate can be set as needed, and the channel size can be set according to the cable to be installed, so as to utilize the plate surface space and accommodate different ranges of cable diameters. When this device leaves the factory, all channels are pre-nested with cold-shrink support tubes, and dust plugs are placed at the ports of the channels and the cold-shrink support tubes to protect them. The cold-shrink support tubes are made of a polymer material with shape memory effect; that is, during factory production, the cold-shrink support tubes are heated and expanded to a larger uniform diameter, and then cooled and shaped in the expanded state. At the factory, the cold-shrink support tubes are pre-installed in the channels, used to expand and seal the channels, and can automatically shrink after being pulled out. In addition, dust plugs are placed at the ends of the cold shrink support tube to prevent dust and dirt during transportation and storage, keeping the inner cavity of the cold shrink support tube clean. The cold shrink support tube shrinks rapidly and evenly due to its "shape memory effect," thus tightly wrapping the cable and forming a good seal.

[0023] After the user inserts the cable into the channel, they pull out the cold-shrink support tube. This pulling action effectively releases the constraint of the cold-shrink support tube. Once pulled out, the cold-shrink support tube automatically, rapidly, and extremely evenly shrinks radially without the need for any external tools or heat, relying on the elastic memory of its material. The cold-shrink support tube has a very high shrinkage rate, allowing it to tightly fit various cable specifications, tightly wrapping the cable to form a good seal and preventing any damage that could be caused by human operation. The core action of the entire installation process is "straight-line pulling out the cold-shrink support tube," a zero-damage, absolutely uniform force-distribution action. It completely eliminates the uncontrollable and destructive "rotational tearing" operation of traditional methods, ensuring the integrity and smoothness of the sealing hole edge from the source.

[0024] In summary, the cold-shrink multi-hole wire guide provided by this utility model can utilize the space of the support plate, accommodate different wire diameters, and form a smooth, complete, and rounded sealing hole after operation, thus preventing product sealing failure caused by improper operation.

[0025] In addition, this utility model also provides an electrical device including the above-mentioned cold-shrink multi-hole wiring board. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] The core of this invention is to provide a cold-shrink multi-hole wiring board, which can utilize the space of the support plate, accommodate different wire diameters, and form a smooth, complete, and rounded sealing hole after operation, thus preventing product sealing failure due to improper operation. Another core aspect of this invention is to provide an electrical device including the aforementioned cold-shrink multi-hole wiring board.

[0037] Please refer to Figure 1 and Figure 2 This specific embodiment provides a cold-shrink multi-hole threading board, including:

[0038] The cable guide plate 1 includes a support plate 11 and at least one channel 12 perpendicularly disposed on the support plate 11;

[0039] The cold shrink support tube 2 is pre-expanded and shaped and embedded in the channel 12. When the cable 4 is not inserted into the channel 12, the cold shrink support tube 2 expands the sealed channel 12. When the cable 4 is inserted into the channel 12, the cold shrink support tube 2 is pulled out and automatically shrinks.

[0040] Dust plug 3 is located at the port of cold shrink support tube 2.

[0041] In practical applications, the shape, structure, size, and material of the threading plate 1, cold shrink support tube 2, and dust plug 3 can be determined according to the actual situation and needs.

[0042] When using the cold-shrink multi-hole cable tray provided by this utility model, at least one channel 12 vertically disposed on the support plate 11 can be set as needed, and the size of the channel 12 can be set according to the cable 4 to be installed, so as to utilize the plate space of the support plate 11 and be compatible with different ranges of cable 4 diameters. When this device leaves the factory, all channels 12 are pre-nested with cold-shrink support tubes 2, and dust plugs 3 are disposed at the ports of the channels 12 and the cold-shrink support tubes 2 to protect the cold-shrink support tubes 2. The cold-shrink support tubes 2 are made of polymer materials with shape memory effect. That is, during factory production, the cold-shrink support tubes 2 are heated and expanded to a larger uniform diameter, and cooled and shaped in the expanded state; when leaving the factory, the cold-shrink support tubes 2 are pre-placed in the channels 12. The cold-shrink support tubes 2 are used to expand and seal the channels 12, and the cold-shrink support tubes 2 can automatically shrink after being pulled out. In addition, the dust plug 3 is inserted into the port of the cold shrink support tube 2 to prevent dust and dirt during transportation and storage, and to keep the inner cavity of the cold shrink support tube 2 clean. That is, the cold shrink support tube 2 shrinks quickly and evenly due to its "shape memory effect", thereby tightly wrapping the cable 4 and forming a good sealing effect.

[0043] After the user inserts cable 4 into channel 12, the cold shrink support tube 2 is pulled out. The user's pulling-out operation effectively releases the constraint of the cold shrink support tube 2. Once pulled out, the cold shrink support tube 2 automatically, rapidly, and extremely evenly shrinks radially without the need for any external tools or heat, relying on the elastic memory of its material. The shrinkage rate of the cold shrink support tube 2 is extremely high, allowing it to tightly fit various specifications of cable 4, tightly wrapping the cable 4 to form a good seal and avoiding any damage that might be caused by human operation. The core action of the entire installation process is "straight-line pulling out of the cold shrink support tube 2," an action that causes zero damage to the surrounding structure and distributes force absolutely evenly. It completely eliminates the uncontrollable and destructive operation of "rotation and tearing" in traditional solutions, ensuring the integrity and smoothness of the sealing hole edge from the root.

[0044] In summary, the cold-shrink multi-hole wire guide provided by this utility model can utilize the space of the support plate 11, accommodate different wire diameters, and form a smooth, complete, and rounded sealing hole after operation, thus preventing product sealing failure caused by improper operation.

[0045] In one embodiment, the cold-shrink support tube 2 comprises a polymer material component with shape memory effect.

[0046] It should be noted that the cold-shrink support tube 2 is a key component of this device, and it is made of a polymer material with shape memory effect. During factory production, the cold-shrink support tube 2 is heated and expanded to a larger, uniform diameter, and then cooled and shaped in the expanded state. When the device leaves the factory, the cold-shrink support tube 2 is pre-positioned in the center of the channel 12 (which can be configured as an elastic seal). The function of the cold-shrink support tube 2 is not only to expand the sealing channel 12, but also to automatically shrink after being pulled out, so that the pulled-out cold-shrink support tube 2 can tightly fit various specifications of cables 4, tightly wrap the cables 4, and form a good seal.

[0047] This application is the first to incorporate the cold-shrink support tube 2 as part of the threading process. The cold-shrink support tube 2 is pre-expanded and shaped at the factory, and the user's action of pulling out the cold-shrink support tube 2 is essentially releasing its constraint. Once pulled out, the cold-shrink support tube 2 can automatically, rapidly, and extremely uniformly shrink radially without the aid of any external tools or heat, relying on the elastic memory of its material. The shrinkage rate of the cold-shrink support tube 2 is extremely high, which can closely fit various wire diameters and avoid any damage that may be caused by human operation.

[0048] In one embodiment, the support plate 11 includes a rigid material component so that the support plate 11 can effectively support multiple channels 12, each channel 12 being provided with a cold-shrink support tube 2 for subsequent threading operations.

[0049] In one embodiment, the channel 12 includes an elastic material element to enable the channel 12 to be configured as an elastic seal, better embedding the cold shrink support tube 2 and sealing the cable 4.

[0050] In one embodiment, the dust plug 3 comprises a silicone or plastic component. Alternatively, the dust plug 3 may also comprise a fluororubber, PVC, or metal component, etc., as different materials have different properties and are suitable for different scenarios. Furthermore, the dust plug 3 is directly used in conjunction with the inner hole of the cold-shrink support tube 2 to form a closed system, ensuring that the channel 12 through which the cable 4 passes and the inner wall of the cold-shrink support tube 2 remain clean throughout the entire lifecycle from production to use, thus eliminating the risk of contamination of the sealing surface from the source.

[0051] In one embodiment, the dust plug 3 and the channel 12 are threaded or snap-fitted together. A cold-shrink support tube 2 is pre-installed within the channel 12, serving to expand and seal the channel 12. Initially, the length of the cold-shrink support tube 2 is the same as the length of the channel 12. When the dust plug 3 and the port of the cold-shrink support tube 2 are directly used to form a closed system, to prevent the dust plug 3 from easily detaching from the cold-shrink support tube 2, the dust plug 3 and the channel 12 can be detachably connected. This prevents the dust plug 3 at the port of the cold-shrink support tube 2, which does not need to pass through the cable 4, from easily detaching.

[0052] In practical applications, the specific connection method between the dust plug 3 and the channel 12 can be determined according to the actual situation and needs.

[0053] In one embodiment, such as Figure 2 As shown, one end of the dust plug 3 has two opposing handles 31, which are positioned away from the channel 12. When the user needs to insert the cable 4 into the channel 12, the subsequent process requires pulling out the cold shrink support tube 2. To avoid the dust plug 3 obstructing the operation of pulling out the cold shrink support tube 2, the user can first hold the handles 31 to separate the dust plug 3 from the port of the cold shrink support tube 2 (including the end of the channel 12), thus avoiding affecting the subsequent operation of pulling out the cold shrink support tube 2 from the channel 12.

[0054] In one embodiment, such as Figure 1 As shown, the support plate 11 is provided with an assembly part 13. The user can install the support plate 11 to the desired position through the assembly part 13.

[0055] In practical applications, the shape, structure, size, position, and material of the assembly part 13 can be determined according to the actual situation and needs.

[0056] In one embodiment, the support plate 11 and the channel 12 are an integral structure. For example, the support plate 11 and the channel 12 can be made of a single injection-molded material or welded material. Alternatively, the support plate 11 and the channel 12 can be fixed by bolts. Making the support plate 11 and the channel 12 an integral structure is to improve the structural stability of the device and reduce the assembly process.

[0057] It should be noted that the cold-shrink multi-hole cable management board has extremely reliable sealing performance. The shrinkage process of the cold-shrink support tube 2 is automatic, uniform, and radially omnidirectional. The shrinkage force of the cold-shrink support tube 2 is large and durable, forming a seamless, airtight / watertight sealing layer on the outer wall of the cable 4. The sealing performance and consistency of the cold-shrink support tube 2 are far superior to traditional solutions that rely on the soft elasticity of materials. Moreover, the cold-shrink multi-hole cable management board has a smooth sealing interface, and the cable 4 assembly process does not require any destructive processes such as "tearing," "pulling," or "cutting," fundamentally eliminating the risk of sealing failure due to burrs or cracks at the hole edges.

[0058] It should also be noted that the cold-shrink multi-hole threading board has wider compatibility and higher space utilization. For example, three holes can be vertically arranged in a triangular pattern on the support plate 11 (e.g., Figure 4 (As shown) or four channels 12 arranged in a matrix to effectively improve the space utilization of the device. Moreover, the device is easy to operate without damage and has excellent environmental protection and long-term effectiveness.

[0059] In addition to the aforementioned shrinkable multi-hole cable tray, this utility model also provides an electrical device that includes the shrinkable multi-hole cable tray disclosed in the above embodiments.
