Description

Technical Field

[0001] This utility model belongs to the field of cable technology, and in particular relates to a multi-core, multi-control intelligent cable for controlling holiday lighting. Background Technology

[0002] Multi-core, multi-control smart cables play a crucial role in festival celebrations, commercial exhibitions, and various outdoor events. These cables typically contain multiple cores, each controlling one or more groups of lighting equipment to achieve complex lighting effects. However, existing multi-core, multi-control smart cables have some significant design and usage issues, particularly in troubleshooting.

[0003] Specifically, in traditional multi-core cables, once a fault occurs in one core wire after installation, maintenance personnel often need to start from one end of the cable and check each core wire one by one until the fault is found. This "trial and error" method is not only inefficient but also prone to causing unnecessary interference or damage to normally functioning core wires. Furthermore, since cables are usually laid in concealed or hard-to-reach locations, such as underground, inside ceilings, or within walls, this further increases the difficulty and cost of fault finding.

[0004] Therefore, it is essential to invent a multi-core, multi-control smart cable for controlling holiday lighting. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a multi-core, multi-control intelligent cable for controlling holiday lighting, comprising a multi-core cable body, inspection posts, inspection sleeves, sealing heads, insulating tape, and inspection holes. Numerous inspection sleeves are integrally and equidistantly distributed on the multi-core cable body. Several inspection holes are formed in the multi-core cable body and the inspection sleeves. Each inspection hole contains an inspection post, and each inspection post is tightly wound and connected to the corresponding conductor of the multi-core cable body. The sealing head seals the opening of the inspection hole. Multiple turns of insulating tape are wrapped around the outside of the inspection sleeve, and the insulating tape is used to tighten and restrict the sealing head.

[0006] Preferably, the multi-core cable body includes a multi-core insulator, a flame-retardant layer, an armor layer, and a cable outer layer. A plurality of the conductors are arranged in a circular array within the multi-core insulator, and the flame-retardant layer, the armor layer, and the cable outer layer are sequentially arranged on the outside of the multi-core insulator.

[0007] Preferably, the multi-core insulator, flame-retardant layer, armor layer, and outer cable layer are provided with inspection holes that allow the inspection post to pass through.

[0008] Preferably, the maintenance sleeve is mainly composed of armor and insulation layer.

[0009] Preferably, the inspection hole is filled with insulating foam material, which is used to isolate the inspection column from the rest of the structure.

[0010] Preferably, the opening of the inspection hole allows the testing end of a test pen or resistance testing device to pass through and make contact with the inspection post.

[0011] Preferably, the sealing head is made of insulating material and has a "T" shaped cross-section.

[0012] Preferably, the outer surface of the maintenance sleeve is provided with an annular recessed area around which the insulating tape is wrapped, and the annular recessed area of ​​the maintenance sleeve is encapsulated with a detachable steel strip structure, which is located outside the insulating tape.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention significantly improves the convenience of fault location and repair, the cable's protective performance, and the flexibility of maintenance methods. Specifically, by integrating equally spaced maintenance sleeves and opening maintenance holes on the multi-core cable body, and connecting the maintenance posts within the maintenance holes to the conductors, maintenance personnel can easily inspect the condition of the internal core wires by contacting the conductors. This enables rapid and accurate fault location and repair, greatly improving work efficiency while avoiding interference or damage to normal core wires. Furthermore, the insulating tape wrapped around the exterior of the maintenance sleeves and the optional steel strip reinforcement not only significantly enhance the cable's insulation performance and mechanical strength but also effectively resist external environmental erosion and damage, improving the cable's overall protective capability. More advancedly, the design of the maintenance holes allows the testing end of a test pen or resistance testing device to directly penetrate and contact the maintenance posts, enabling real-time monitoring of the core wire condition. This allows maintenance personnel to accurately test the cable's electrical performance without damaging the cable's outer protective layer. Attached Figure Description

[0022] As attached Figure 1 To be continued Figure 3 As shown:

[0023] This utility model provides a multi-core, multi-control intelligent cable for controlling holiday lights, comprising a multi-core cable body 1, inspection posts 2, inspection sleeves 3, sealing heads 4, insulating tape 5, and inspection holes 6. Numerous inspection sleeves 3 are integrally and equidistantly distributed on the multi-core cable body 1. Several inspection holes 6 are formed in the multi-core cable body 1 and the inspection sleeves 3. Each inspection hole 6 contains an inspection post 2, and each inspection post 2 is tightly wound and connected to the corresponding conductor 11 of the multi-core cable body 1. The sealing head 4 seals the opening of the inspection hole 6. Multiple turns of insulating tape 5 are wrapped around the outside of the inspection sleeves 3, and the insulating tape 5 is used to tighten and restrict the sealing head 4.

[0024] Furthermore, the multi-core cable body 1 includes a multi-core insulator 12, a flame-retardant layer 13, an armor layer 14, and an outer cable layer 15. Several conductors 11 are arranged in a circular array within the multi-core insulator 12, forming the basis for power or signal transmission. To further enhance the cable's insulation performance, the multi-core insulator 12 is sequentially wrapped with the flame-retardant layer 13, the armor layer 14, and the outer cable layer 15. The flame-retardant layer 13 effectively prevents the spread of fire in the event of a cable fire, the armor layer 14 provides additional mechanical protection against external damage, and the outer cable layer 15, as the outermost layer, not only provides protection but also ensures the cable's aesthetics and durability.

[0025] Furthermore, to facilitate inspection and maintenance, inspection holes 6 are provided on the multi-core insulation 12, flame-retardant layer 13, armor layer 14, and outer cable layer 15, allowing the inspection post 2 to pass through. This design enables maintenance personnel to easily inspect the conductor 11 inside the cable by contacting the inspection post 2, thereby performing necessary inspections and maintenance.

[0026] Furthermore, the maintenance sleeve 3 is an important component of the multi-core cable. It mainly consists of armor and insulation layers, providing additional protection and support for the cable. The installation of the maintenance sleeve 3 not only helps to secure the cable but also allows the inspection hole 6 to exist more stably, facilitating subsequent maintenance work.

[0027] Furthermore, to ensure the safety and stability of the cable, the inspection hole 6 is filled with insulating foam material. This material effectively isolates the inspection post 2 from the other structures of the cable, preventing leakage of current or signals, and also protects the inspection post 2 and the internal structure of the cable.

[0028] Furthermore, the opening of the inspection hole 6 is designed to allow the testing end of a test pen or resistance testing device to pass through and make contact with the inspection post 2. This design enables maintenance personnel to accurately test the electrical performance of the cable without damaging the cable's outer protective layer, greatly improving the efficiency and accuracy of maintenance.

[0029] Furthermore, the plug 4 is a structure made of insulating material with a "T" shaped cross-section. This design not only ensures the stability and durability of the plug 4, but also allows it to tightly seal the opening of the inspection hole 6, preventing external substances such as moisture and dust from entering the cable, thereby ensuring the electrical performance and safety of the cable.

[0030] Furthermore, to enhance the stability and protection of the maintenance sleeve 3, its outer surface is provided with an annular recessed area wrapped with insulating tape 5. In addition, the annular recessed area of ​​the maintenance sleeve 3 is also encapsulated with a removable steel strip structure, which is located outside the insulating tape 5. This design not only improves the mechanical strength of the maintenance sleeve 3 but also enables it to better resist the erosion and damage of the external environment, thereby extending the service life of the cable.

[0031] The troubleshooting process steps are as follows:

[0032] First, prepare the repair tools: ensure that you have prepared a test pen, resistance testing equipment, 5 pieces of insulating tape, 4 replacement plugs (if needed), and necessary hand tools such as screwdrivers and wrenches.

[0033] Secondly, locate the maintenance point: Based on the cable laying drawings or on-site markings, find the corresponding maintenance bracket 3 on the main body 1 of the multi-core cable that needs maintenance. Since the maintenance brackets 3 are evenly distributed, the target location can be quickly located.

[0034] Next, remove the plug head 4: Using an appropriate tool, such as a screwdriver or wrench, gently pry open or unscrew the plug head 4. Be careful to be gentle and avoid damaging the insulation material around the plug head 4 or the access hole 6.

[0035] Next, perform electrical testing: Insert the testing end of a test pen or resistance testing device into the inspection hole 6, making contact with the inspection post 2. Use the readings from the testing device to determine if the electrical performance of the internal conductor 11 of the cable is normal. If any abnormality is found, further analysis of the cause is required.

[0036] Next, troubleshooting: If electrical testing reveals a fault, take appropriate repair measures based on the test results. For example, if conductor 11 is open-circuited or short-circuited, it may be necessary to replace conductor 11. Simply cut the cable in that area and replace it with a new cable. During the repair process, ensure that the inspection post 2 is tightly wrapped around conductor 11 and refill with insulating foam material to isolate it from other structures.

[0037] Next, reinstall the sealing head 4: After maintenance, use a new or clean sealing head 4 to reseal the opening of the access hole 6. Ensure that the sealing head 4 is securely installed and fits tightly against the edge of the access hole 6 to prevent external substances from entering the cable.

[0038] Finally, reinforce the maintenance sleeve: rewrap the insulating tape 5 around the annular recessed area of ​​the maintenance sleeve 3 and install a detachable steel strip structure for reinforcement. Ensure that both the insulating tape 5 and the steel strip structure are properly installed to improve the stability and protective properties of the maintenance sleeve 3.

[0039] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
