Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cable manufacturing, and particularly relates to a high-stability interwoven and twisted hot-air self-adhesive silk-covered wire. BACKGROUND

[0002] In the prior art, high-stability and anti-interference interwoven and twisted hot-air self-adhesive silk-covered wire plays a crucial role in the field of electronic device wiring. It can tightly interweave multiple wires together to form a stable wire bundle, improve the mechanical strength and electrical performance of the wire, and enhance the anti-interference ability and service life of the wire. However, there are some deficiencies in the high-stability and anti-interference interwoven and twisted hot-air self-adhesive silk-covered wire on the market.

[0003] In the prior art, the traditional hot-air self-adhesive silk-covered wire does not perform ideally in terms of mechanical strength and stability. On the one hand, the interweaving structure of some hot-air self-adhesive silk-covered wires is not tight enough, which leads to problems such as loosening and cracking of the wire bundle under external force or during long-term use, affecting its electrical performance and service life. On the other hand, the bonding performance of some hot-air self-adhesive silk-covered wires is poor, and the bonding force may decrease in high-temperature or humid environments, resulting in reduced stability of the wire bundle and potential safety hazards.

[0004] In addition, the existing high-stability and anti-interference interwoven and twisted hot-air self-adhesive silk-covered wire also has some unreasonable aspects in terms of bonding performance and environmental resistance. For example, the bonding layer of some silk-covered wires easily ages and becomes brittle at high temperatures, resulting in poor bonding effect and failing to meet the requirements of long-term stable use. At the same time, some silk-covered wires are prone to moisture absorption in humid environments, affecting their insulation performance and mechanical strength and reducing the reliability and durability of the product.

[0005] Therefore, in order to comprehensively improve the mechanical strength, stability, bonding performance and environmental resistance of high-stability and anti-interference interwoven and twisted hot-air self-adhesive silk-covered wire, improvements are needed to improve the safety and reliability of the product and enhance the user experience.

[0022] In actual implementation, by designing the specifications of the first and second self-adhesive filaments and through a multi-layer structure design, the protection and electromagnetic shielding of the wire core are achieved.

[0023] Specifically, the first and second self-adhesive threads adhere to each other upon heating, forming a tight protective layer that enhances the mechanical strength and stability of the wire core and prevents external physical damage and environmental factors from affecting it. By covering the outer periphery of the second self-adhesive thread with a shielding layer, external electromagnetic interference is effectively blocked, ensuring the stability of current transmission and signal integrity within the wire core, which is of great significance for wiring in electronic equipment. The outermost sheath layer further improves the overall mechanical strength and abrasion resistance of the wire sheath, while also providing insulation to prevent current leakage and short circuits.
