Description

Technical Field

[0001] This utility model belongs to the field of signal cable technology, and in particular relates to a signal cable with protective function. Background Technology

[0002] The existing air conditioner signal cable is a crucial component connecting the indoor and outdoor units of the air conditioner. It is responsible for transmitting control signals and data to ensure the normal operation of the air conditioning system. If the signal cable breaks, communication between the indoor and outdoor units will be interrupted, which may lead to problems such as the air conditioner failing to start, unable to adjust the temperature, or unable to respond to remote control commands. Therefore, a protective conduit needs to be nested outside the air conditioner signal cable for separation and independent protection. This means that the air conditioner signal cable is pre-installed in the protective conduit during manufacturing and sold accordingly; it can then be cut to the required length during use, eliminating the need for temporary conduit installation on-site.

[0003] Chinese Patent Application No.: 2020225495220, entitled: A Covered Signal Cable, comprising a sheath tube and a signal cable. The sheath tube is a hollow flexible tube that covers the outer wall of the signal cable. The length of the sheath tube is the same as the length of the signal cable. The outer wall surface of the sheath tube is a corrugated tube. The sheath tube and the signal cable are integrated into one unit. The covered signal cable is directly threaded through the outer tube. Workers can use it directly on site without needing to thread a conduit. This avoids the waste of manpower and time in the traditional method of laying the cable first and then threading it through the conduit. It is simple to operate, easy to use, and improves the protection of the signal cable by the sheath tube.

[0004] The aforementioned patent also has the following problems: Since the air conditioner signal line is an important component connecting the indoor and outdoor units of the air conditioner, and the sheath is exposed to sunlight for a long time, it is prone to aging and embrittlement, resulting in a shortened service life and affecting the protection of the air conditioner signal line by the sheath. Therefore, this utility model proposes a signal line with protective function to solve the above problems. Utility Model Content

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please see Figures 1 to 4 This utility model provides a technical solution: a signal line with protective function, including a sheath tube 1 and a signal cable 2; the sheath tube 1 covers the outer wall of the signal cable 2, and the length of the sheath tube 1 is the same as the length of the signal cable 2; the sheath tube 1 is either a corrugated tube or a threaded tube, and the sheath tube 1 includes an inner layer 11 and an anti-ultraviolet layer 12, and the outer side of the anti-ultraviolet layer 12 is covered with a silicone protective layer, so that the signal cable 2 can shield external signals.

[0029] Furthermore, the UV-resistant layer 12 is used to resist ultraviolet rays.

[0030] For further details, please refer to Figure 4The signal cable 2 includes at least one signal line 21 and a first insulation layer 22, the first insulation layer 22 covering the outside of the signal line 21.

[0031] For further details, please refer to Figure 4 The signal line 21 is provided with a first shielding signal layer 24 and a second shielding signal layer 25. The first shielding signal layer 24 is copper foil and the second shielding signal layer 25 is copper mesh.

[0032] For further details, please refer to Figure 4 A protective layer 23 is provided between the signal line 21 and the first shielded signal layer 24, and a second insulating layer 26 is provided on the outside of the second shielded signal layer 25.

[0033] In this embodiment, the inner layer 11 can be made of PE or PVC material, or blow-molded from nylon material or modified PP polypropylene material. The UV-resistant layer 12 is a titanium dioxide or zinc oxide layer, which achieves physical shielding by reflecting / scattering ultraviolet rays, resulting in high safety and strong stability.

[0034] Since the signal transmitted by the signal cable 2 is generally very small, a shielding layer is provided on the outside of the signal cable 2 to avoid interference from signals on the outer wall. Specifically, the signal cable 2 includes at least one signal wire 21 and a first insulation layer 22. The signal wire 21 is surrounded by a first shielding signal layer 24 and a second shielding signal layer 25. The first shielding signal layer 24 is copper foil, and the second shielding signal layer 25 is copper mesh. The first and second shielding signal layers 24 and 25 cover the signal wire 21 (conductor). The first and second shielding signal layers 24 and 25 need to be grounded so that external interference signals can be conducted to the ground, preventing interference signals from entering the inner conductor and reducing signal loss. A protective layer 23 is provided between the signal line 21 and the first shielded signal layer 24. The protective layer 23 separates the signal line 21 from the first shielded signal layer 24. The protective layer 23 wraps around the signal line 21 (conductor) and plays a role in electrical insulation to prevent signal leakage. It can effectively isolate the signal line 21 and the first shielded signal layer 24 to ensure stable signal transmission. The second insulating layer 26 is for protecting a single signal line 21, and the first insulating layer 22 is for protecting multiple signal lines 21. The first insulating layer 22 and the second insulating layer 26 are made of insulating soft plastic material, which not only plays a role in insulation but also protects the signal cable 2 from mechanical damage and chemical corrosion, and increases the mechanical strength of the signal cable 2, playing a role in tensile and compressive resistance.

[0035] The inner layer 11 and the UV-resistant layer 12 in the sheath tube 1 can be made in two colors. The two colors can also be used to check whether the UV-resistant layer 12 in the sheath tube 1 completely covers the outer wall of the inner layer 11. The outer side of the UV-resistant layer 12 is covered with a silicone protective layer, which can protect the outer wall of the UV-resistant layer 12.

[0036] The working principle of this utility model is as follows: The outer wall of the sheath tube 1 is an anti-ultraviolet layer 12, which is a titanium dioxide or zinc oxide layer. It achieves physical shielding by reflecting / scattering ultraviolet rays, which is highly safe and stable. The anti-ultraviolet layer 12 can extend the service life of the sheath tube 1 and prevent the sheath tube 1 from aging and becoming brittle under direct sunlight. The signal cable 2 is provided with a shielding layer, which is grounded. External interference signals can be guided to the ground by the shielding layer, preventing interference signals from entering the signal line 21 (conductor) and reducing the loss of transmitted signals.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
