Description

Technical Field

[0001] This utility model relates to a Category 6 unshielded twisted pair cable with good moisture resistance and insulation, belonging to the field of twisted pair cables. Background Technology

[0002] In modern communications and data transmission, Category 6 unshielded twisted-pair cable serves as a crucial transmission medium, widely used in local area networks (LANs), data centers, and connections between various electronic devices. However, with the continuous improvement of data transmission rates and the increasing complexity of application environments, the performance requirements for twisted-pair cables are also rising. Especially in terms of moisture resistance and insulation performance, existing twisted-pair cable designs often fall short of current demands.

[0003] Category 6 unshielded twisted-pair cables typically use a single outer sheath material and a simple insulation structure, a design that has significant shortcomings in terms of moisture resistance and insulation. First, a single outer sheath material is often insufficient to effectively resist the intrusion of external moisture, leading to easy dampness inside the cable and consequently affecting the stability and reliability of data transmission. Second, the simple insulation structure cannot provide adequate insulation protection, making it susceptible to breakdown or short circuits under high voltage or strong electromagnetic interference environments.

[0020] 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.

[0021] Please see Figure 1 This utility model provides a technical solution: a Category 6 unshielded twisted pair cable with good moisture resistance and insulation, including an outer sheath 1, a cross frame 2 and four twisted copper conductors 3. The outer sides of the four twisted copper conductors 3 are provided with HDPE insulation layers 4, and the outer sheath 1 is provided with a reinforcing structure to enhance the moisture resistance and insulation performance of the cable.

[0022] like Figure 1 As shown, the reinforced structure includes a semiconducting shielding layer 5 fixedly connected to the outside of the outer skin 1, a metal shielding layer 6 fixedly connected to the outside of the semiconducting shielding layer 5, a silicone layer 7 fixedly connected to the outside of the metal shielding layer 6, and an outer protective layer 8 fixedly connected to the outside of the silicone layer 7.

[0023] It should be noted that the cross-shaped frame 2 divides the inner side of the outer sheath 1 into four installation areas, and the four twisted-pair copper wires 3 are respectively installed in the corresponding installation areas. By dividing the inner side of the outer sheath 1 into four independent installation areas, it can be ensured that each twisted-pair copper wire 3 has sufficient space for wiring, avoiding interference between lines and improving the stability and efficiency of data transmission. This design enables Category 6 unshielded twisted-pair cable to have better performance in high-speed data transmission scenarios.

[0024] The thickness of the HDPE insulation layer 4 is between 0.2 mm and 0.5 mm. This thickness prevents current leakage or short circuits while maintaining sufficient flexibility and durability for easy installation and use. In addition, it reduces signal attenuation during transmission, improving signal integrity and transmission distance.

[0025] The outer surface of the silica gel layer 7 is coated with a molecular sieve desiccant coating 701. The addition of the molecular sieve desiccant coating 701 further enhances the moisture-proof performance of the line. The molecular sieve desiccant has a strong moisture absorption capacity and can effectively absorb the moisture around the line, preventing moisture from penetrating into the interior of the line.

[0026] The outer sheath 1, the semiconducting shielding layer 5, and the metal shielding layer 6 are fixedly connected to each other by hot pressing. Hot pressing is a reliable and efficient connection method. It uses high temperature and pressure to tightly bond different materials together to form a strong connection. Through this connection method, the outer sheath 1, the semiconducting shielding layer 5, and the metal shielding layer 6 can be tightly combined to form an integral structure, which improves the overall strength and anti-interference ability of the line. At the same time, hot pressing can also ensure the conductivity and insulation performance between the layers, ensuring the normal operation of the line.

[0027] The metal shielding layer 6, silicone layer 7, and outer sheath 8 are fixedly connected to each other by adhesive. The metal shielding layer 6, silicone layer 7, and outer sheath 8 are tightly bonded together by adhesive to form a complete protective layer. This connection method can not only enhance the overall strength of the line, but also improve the line's moisture resistance and corrosion resistance. At the same time, the adhesive connection can also ensure a tight fit between the layers, reducing the possibility of air gaps and moisture penetration.

[0028] The outer surface of the outer sheath 8 has horizontal lines and eight grooves. The horizontal lines on the outer sheath 8 increase the friction of the thread, making it easier to grip and fix during installation and use. Each groove has a sponge strip 9 fixedly connected to its inner side. The sponge material of the sponge strip 9 has moisture-absorbing properties, thereby preventing moisture from penetrating into the inner side of the outer sheath 1 and thus enhancing the moisture-proof performance of the thread.

[0029] In addition, the semiconducting shielding layer 5 is made of a semiconducting material, specifically a thin semiconducting composite material with low resistivity. This semiconducting composite material is generally based on a polymer matrix, and its semiconducting properties are achieved by adding conductive fillers to the polymer matrix. Simultaneously, to maintain the material's processability and mechanical properties, crosslinking agents, antioxidants, processing aids, and other additives are added. The metal shielding layer 6 is made of polyethylene material to improve the safety and durability of the line.

[0030] The working principle of the above embodiments is as follows:

[0031] First, the basic structure of the twisted pair cable consists of an outer sheath 1, a cross frame 2, and four twisted copper wires 3. The cross frame 2 divides the inner side of the outer sheath 1 into four independent installation areas, ensuring that each twisted copper wire 3 has enough space for wiring, avoiding interference between lines, thereby improving the stability and efficiency of data transmission. Second, in order to enhance the moisture-proof and insulation performance of the cable, this utility model sets a reinforcing structure on the outer side of the outer sheath 1 of the twisted pair cable, including a semi-conductive shielding layer 5, a metal shielding layer 6, a silicone layer 7, and an outer sheath 8.

[0032] The semiconducting shielding layer 5 is made of semiconducting material and has low resistivity. It can uniformly distribute the electric field and prevent partial discharge or breakdown caused by electric field concentration, thereby improving the insulation performance of the wire.

[0033] The metal shielding layer 6 is made of polyethylene material, which has good conductivity and mechanical strength. The metal shielding layer 6 can further shield external electromagnetic interference and protect the internal circuits from being affected.

[0034] The silica gel layer 7 serves as a moisture-proof layer, and its outer surface is coated with a molecular sieve desiccant coating 701. The molecular sieve desiccant has a strong moisture absorption capacity and can effectively absorb the moisture around the production line, preventing moisture from penetrating into the interior of the production line. The combined use of the silica gel layer 7 and the molecular sieve desiccant coating 701 further enhances the moisture-proof performance of the production line.

[0035] The outermost protective layer 8 has horizontal lines and eight grooves on its outer surface. The horizontal lines increase the friction of the thread, making it easier to grip and fix during installation and use. The sponge strip 9 fixedly connected to the inside of the grooves has moisture-absorbing properties, which can further prevent moisture from penetrating into the interior of the thread.

[0036] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
