Description

Technical Field

[0001] This utility model belongs to the field of cable technology for electronic equipment, and specifically relates to a cable anti-twist structure. Background Technology

[0002] With the widespread use of electronic devices such as audio equipment and televisions, cables, as crucial components connecting various devices, directly impact the stability and lifespan of the entire system. However, these cables encounter several problems during practical use, one of the most prominent being their susceptibility to twisting. This causes the internal conductors to deform or even break under stress. Such twisting not only degrades signal transmission quality but can also lead to permanent damage, affecting the normal operation of the equipment. Furthermore, twisting can cause wear on the cable's external insulation, further increasing safety hazards.

[0003] Existing anti-torsion technologies mainly include using stronger materials, increasing cable diameter, and employing special braiding methods. However, these methods often increase the weight and cost of the cable, and their anti-torsion effect is not ideal. Furthermore, once the cable is damaged by torsion, it can only be replaced. Therefore, developing a technical solution that can effectively prevent cable torsion while maintaining lightweight and low cost has become an urgent problem to be solved. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution.

[0005] A cable anti-torsion structure, fitted onto a cable body, includes an anti-torsion spring, with fixing components at both ends for secure connection to the cable body. The anti-torsion spring provides a restoring force to the cable body after torsion, and the fixing components secure the anti-torsion spring to the cable body.

[0006] As a preferred technical solution for a cable anti-torsion structure, specifically, the fixing component includes a fastening base and a fastening sleeve. The fastening base is fixedly connected to the anti-torsion spring, and the fastening sleeve is slidably fitted onto the fastening base. One end of the fastening base is provided with a frustum, which includes several fastening flaps arranged around the cable body as its axis. The fastening sleeve has a fastening wall that matches the outer surface of the frustum. Through the cooperation of the fastening flaps and the fastening wall, the cable anti-torsion structure can be firmly fixed to the cable body without damaging the cable, preventing the cable anti-torsion structure from rotating relative to the cable body.

[0007] As a preferred technical solution for a cable anti-twist structure, specifically, the other end of the fastening seat is provided with a fixing part having an external thread on its outer surface; the fastening sleeve is provided with a first internal thread that mates with the external thread. The threaded connection provides reliable mechanical fixation, allows for easy adjustment of the tightening force, and ensures that the connection between the anti-twist structure and the cable is both secure and easy to disassemble.

[0008] As a preferred technical solution for a cable anti-twist structure, the fixing component further includes a fixing seat, which has a second internal thread that mates with the external thread. The fixing seat can limit the tightening of the fastening seat, preventing over-tightening and damage to the cable body.

[0009] As a preferred technical solution for cable anti-twist structure, specifically, the outer surface of the fastening sleeve is provided with anti-slip texture. The anti-slip texture increases the friction when the hand contacts the fastening sleeve, making it easier for installers to operate.

[0010] As a preferred technical solution for cable anti-torsion structure, it specifically includes a sheath, in which the anti-torsion spring is installed. The sheath protects the anti-torsion spring from external environmental factors (such as corrosion and abrasion), extending its service life, and also protects the cable body.

[0011] As a preferred technical solution for cable anti-torsion structure, specifically, the ratio of the length to the diameter of the anti-torsion spring is greater than 5 and less than 15. This ratio ensures that the anti-torsion spring has good flexibility and recovery ability, and can quickly rebound to its initial state after being subjected to a certain torsional force.

[0012] As a preferred technical solution for cable anti-torsion structure, specifically, the ratio of the diameter of the anti-torsion spring to the wire diameter is less than 10. This ratio ensures that the anti-torsion spring has good flexibility and recovery ability, and can quickly rebound to its initial state after being subjected to a certain torsional force.

[0013] Compared with the prior art, this application has the following beneficial effects: it utilizes the good flexibility and recovery ability of springs to prevent cable twisting. Attached Figure Description

[0022] Reference Figures 1 to 3 A cable anti-torsion structure is fitted onto a cable body 10, including an anti-torsion spring 21. Both ends of the anti-torsion spring 21 are fitted with fixing components for fixed connection to the cable body 10. The anti-torsion spring 21 provides a restoring force to the cable body 10 after torsion, and the fixing components are used to fix the anti-torsion spring 21 to the cable body 10.

[0023] Specifically, the fixing assembly includes a fastening base 30 and a fastening sleeve 40. The fastening base 30 is fixedly connected to the anti-torsion spring 21, and the fastening sleeve 40 is slidably fitted onto the fastening base 30. One end of the fastening base 30 is provided with a frustum, which includes a plurality of fastening flaps 31 arranged around the cable body 10 as the axis. The fastening sleeve 40 is provided with a fastening wall that fits the outer surface of the frustum. Through the cooperation of the fastening flaps 31 and the fastening wall, the cable anti-torsion structure can be firmly fixed to the cable body 10 without damaging the cable, preventing the cable anti-torsion structure from rotating relative to the cable body 10.

[0024] The other end of the fastening seat 30 is provided with a fixing part having an external thread 32 on its outer surface; the fastening sleeve 40 is provided with a first internal thread 41 that mates with the external thread 32. The threaded connection provides reliable mechanical fixation, allows for easy adjustment of the tightening force, and ensures that the connection between the anti-torsion structure and the cable is both stable and easy to disassemble. The fixing assembly also includes a fixing seat 50, which is provided with a second internal thread 51 that mates with the external thread 32. The fixing seat 50 can restrict the fastening seat 30 to prevent over-tightening and damage to the cable body 10. The outer surface of the fastening sleeve 40 is provided with anti-slip texture 42. The anti-slip texture 42 increases the friction when the hand contacts the fastening sleeve 40, making it easier for installers to operate.

[0025] To ensure the rebound performance of the anti-torsion spring 21, the cable anti-torsion structure also includes a sheath 20, within which the anti-torsion spring 21 is housed. The sheath 20 protects the anti-torsion spring 21 from external environmental factors (such as corrosion and abrasion), extending its service life, and also protects the cable body 10. The sheath 20 is made of weather-resistant material, possessing excellent UV resistance and anti-aging properties. The length-to-diameter ratio of the anti-torsion spring 21 is greater than 5 and less than 15, and the diameter-to-wire diameter ratio is less than 10. This ratio ensures that the anti-torsion spring 21 has good flexibility and resilience, enabling it to quickly rebound to its initial state after being subjected to a certain torsional force.

[0026] The scope of protection of this utility model includes, but is not limited to, the above embodiments. The scope of protection of this utility model is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
