Description

Technical Field

[0001] This utility model relates to the field of wire technology, and in particular to a special wire for central air conditioning. Background Technology

[0002] Central air conditioning is an air conditioning system that connects multiple terminal devices, such as indoor units and fan coil units, to achieve unified or independent temperature control in multiple rooms through a single main unit. The main unit needs to be connected to the terminal devices via dedicated power lines.

[0003] Existing central air conditioning wiring typically consists of insulated cores. However, during operation, the vibrations generated by the central air conditioning system cause the wiring to sway, leading to friction with external objects and potential electrical damage. This results in poor insulation. Furthermore, the wiring is susceptible to interference from external electromagnetic signals, causing unstable current delivery and poor performance. Therefore, we propose a new type of wiring specifically designed for central air conditioning systems. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a special wire for central air conditioning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a special wire for central air conditioning is designed, including a wire core, a first insulation layer on the outer surface of the wire core, a tensile layer on the outer surface of the first insulation layer, a first shielding layer on the outer surface of the tensile layer, a second insulation layer on the outer surface of the first shielding layer, and a protective sleeve on the outer surface of the second insulation layer.

[0006] A wear-resistant sleeve is provided on the outer surface of the protective case, and a second shielding layer is installed on the inner surface of the wear-resistant sleeve. The inner surface of the second shielding layer is in contact with the outer surface of the protective case.

[0007] A pair of connecting rings are installed at both ends of the wear-resistant sleeve, and each pair of connecting rings, the wear-resistant sleeve, and the second shielding layer are provided with open slots. An annular groove is formed between each pair of connecting rings, and an elastic tube clamp is provided between each pair of connecting rings. The elastic tube clamp is sleeved on the end of the wear-resistant sleeve.

[0008] Preferably, the tensile layer is made of aramid fiber material.

[0009] Preferably, both the first insulating layer and the second insulating layer are made of polyvinyl chloride.

[0010] Preferably, the flexible tube clamp is made of flexible plastic or flexible metal material.

[0011] Preferably, the two sides of the elastic pipe clamp abut against the sides of the corresponding connecting ring.

[0012] Preferably, both ends of the elastic tube clamp are connected to connecting plates, and the two connecting plates are staggered.

[0013] Preferably, both the first shielding layer and the second shielding layer are made of aluminum alloy wire.

[0014] The design scheme proposed in this utility model has the following beneficial effects in application:

[0015] The wear-resistant sleeve can be fixed to the surface of the wire by means of a flexible tube clamp, so that the wear-resistant sleeve can isolate the wire from external objects. When the wire is shaken by the vibration of the central air conditioner, the wear-resistant sleeve can protect the wire from friction with external objects, and the wire sheath will not be damaged, thus improving the protection effect.

[0016] The first insulation layer encloses the wire core, isolating it from external electromagnetic signals. The second shielding layer further shields and isolates external electromagnetic signals, ensuring that the wire core is not affected by external electromagnetic signals when transmitting current, resulting in stable current delivery and improved performance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4A special wire for central air conditioning includes a wire core 1, a first insulation layer 2 on the outer surface of the wire core 1, and a tensile layer 3 on the outer surface of the first insulation layer 2. The tensile layer 3 is made of aramid fiber material or other flexible material with tensile properties. The tensile layer 3 can increase the tensile strength of the wire, so that the wire will not break when it is pulled.

[0024] like Figure 1 As shown, a first shielding layer 4 is provided on the outer surface of the tensile layer 3. The first shielding layer 4 is made of aluminum alloy wire. In actual use, the first shielding layer 4 can isolate external electromagnetic signals, so that the core 1 will not be affected by electromagnetic signals in the external environment when transmitting current.

[0025] like Figure 1 As shown, a second insulating layer 5 is also installed on the outer surface of the first shielding layer 4. Both the first insulating layer 2 and the second insulating layer 5 are made of polyvinyl chloride material. The first insulating layer 2 and the second insulating layer 5 can provide insulation protection for the wire core 1, preventing leakage of the wire core 1 and causing a short circuit.

[0026] like Figure 1 and Figure 2 As shown, a protective sleeve 6 is fitted on the outer surface of the second insulating layer 5. The protective sleeve 6 can wrap the second insulating layer 5 and protect it, so that the second insulating layer 5 will not rub against external objects during use.

[0027] like Figure 1 and Figure 3 As shown, a wear-resistant sleeve 9 is provided on the outer surface of the protective sleeve 6. The wear-resistant sleeve 9 is supported by wear-resistant rubber material, or other flexible materials with wear-resistant properties. In actual use, the wear-resistant sleeve 9 can wrap the wire. Under the vibration generated by the operation of the central air conditioner, the wire will shake. The wear-resistant sleeve 9 will shake with the wire and rub against the inner wall of the wiring trough instead of the wire, thus protecting the wire.

[0028] like Figure 1 As shown, a second shielding layer 12 is installed on the inner surface of the wear-resistant sleeve 9. The inner surface of the second shielding layer 12 is in contact with the outer surface of the protective sleeve 6. The second shielding layer 12 is made of aluminum alloy wire. The second shielding layer 12 can shield and protect the wire, shielding external electromagnetic signals so that the wire will not be interfered with by external electromagnetic signals when transmitting electrical energy.

[0029] like Figure 1As shown, a pair of connecting rings 7 are installed at both ends of the wear-resistant sleeve 9, and each pair of connecting rings 7 has an opening groove 10 at both ends of the wear-resistant sleeve 9 and the second shielding layer 12, forming an annular groove between each pair of connecting rings 7. An elastic tube clamp 8 is provided between each pair of connecting rings 7, and the elastic tube clamp 8 is fitted onto the end of the wear-resistant sleeve 9. The elastic tube clamp 8 is made of elastic plastic or elastic metal material, such as... Figure 2 and Figure 4 As shown, in actual use, after the wear-resistant sleeve 9 is put on the wire, the elastic tube clamp 8 is put between each pair of connecting rings 7. The elastic force of the elastic tube clamp 8 will squeeze the wear-resistant sleeve 9, so that the opening groove 10 is closed, thus fixing the wear-resistant sleeve 9 on the wire.

[0030] Specifically, in use, the operator places the wear-resistant sleeve 9 on the protective sleeve 6 at a predetermined position, so that the inner surface of the second shielding layer 12 contacts the outer surface of the protective sleeve 6. Then, the elastic clamp 8 is placed on both ends of the wear-resistant sleeve 9. Under its own elastic force, the elastic clamp 8 will contract and squeeze the wear-resistant sleeve 9, tightly fixing the wear-resistant sleeve 9 to the protective sleeve 6. The wear-resistant sleeve 9 can protect the wire, so that when the wire is affected by the vibration generated by the operation of the central air conditioner, the wear-resistant sleeve 9 can isolate the wire from external objects. The wire will not be damaged by shaking caused by the vibration of the air conditioner and friction with external objects, thus improving the protection effect. In addition, during use, the first shielding layer 4 and the second shielding layer 12 can isolate external electromagnetic signals from the wire core 1, so that the wire core 1 will not be hindered by external electromagnetic signals when transmitting current. The current transmitted by the wire core 1 is stable, improving the use effect.

[0031] Furthermore, the two sides of the flexible tube clamp 8 abut against the sides of the corresponding connecting ring 7, so that the connecting ring 7 can limit the flexible tube clamp 8 and prevent the flexible tube clamp 8 from sliding along the wire.

[0032] Furthermore, such as Figure 4 As shown, both ends of the elastic pipe clamp 8 are connected to connecting pieces 11, and the two connecting pieces 11 are staggered. The workers can open both ends of the elastic pipe clamp 8 through the connecting pieces 11, which makes it easy to put the elastic pipe clamp 8 on the end of the wear-resistant sleeve 9, making installation convenient.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
