Description

Technical Field

[0001] This utility model belongs to the field of computer cable technology, specifically a scratch-resistant and wear-resistant outer layer structure for computer cables. Background Technology

[0002] With the widespread use of electronic devices, computer cables have become an indispensable connection medium for office work, study, and daily entertainment. Whether it's frequent movement in a desktop environment, friction and pressure when carried in a backpack, or long-term contact with furniture and the floor in a home setting, the outer layer of a computer cable needs to continuously withstand the wear and tear caused by various physical contacts.

[0003] The existing computer cables mostly have a single coating or simple composite layer design for the outer layer, lacking a targeted support and scratch-resistant structure. As a result, the surface is easily damaged by external scratches and friction during daily use, and the internal core is easily affected by compression and entanglement, resulting in insufficient signal transmission stability.

[0004] Therefore, a scratch-resistant and wear-resistant outer layer structure for computer cables is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a scratch-resistant and wear-resistant outer layer structure for computer cables. This structure effectively solves the problems of poor scratch resistance of the outer layer and easy compression of the inner core in existing computer cables. It significantly improves the scratch resistance and structural stability of the computer cable, effectively disperses bending stress, reduces tensile damage at bending points, prevents cracking of the outer layer and breakage of the inner core, specifically protects the bending area, and further extends the service life of the computer cable.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a scratch-resistant and wear-resistant outer layer structure for a computer cable, comprising a computer cable body, the computer cable body being composed of a base layer, a braided reinforcement layer, and a wear-resistant outer layer body. The inner surface of the base layer is provided with two intersecting partition plates, and the outer surface of the base layer is provided with a plurality of support strips, with grooves formed between adjacent support strips. The braided reinforcement layer is fitted onto the outer side of the base layer, and the inner side of the braided reinforcement layer is provided with snap-fit ​​strips adapted to the grooves. The wear-resistant outer layer body covers the outer side of the braided reinforcement layer, and the outer surface of the wear-resistant outer layer body is provided with a plurality of anti-scratch ridges.

[0007] Preferably, the two partition plates are cross-shaped, and the partition plates and the base layer are integrally formed, and both the partition plates and the base layer are made of modified nitrile rubber.

[0008] Preferably, the partition plate and the inner surface of the base layer enclose four independent receiving cavities, and an inner core is inserted into each receiving cavity.

[0009] Preferably, the cavity is filled with a flexible filler made of flame-retardant foam, which wraps around the outside of the inner core and fits tightly against the inner wall of the cavity and the outer surface of the inner core.

[0010] Preferably, the anti-scratch ridges are evenly distributed along the circumference of the wear-resistant outer layer body, and the number of anti-scratch ridges is equal to the number of support strips, and each anti-scratch ridge corresponds one-to-one with each support strip in the radial direction.

[0011] Preferably, a bending sleeve is slidably fitted onto the outer surface of the wear-resistant outer layer body, and the inner sidewall of the bending sleeve is provided with a guide groove adapted to the anti-scratch ridge.

[0012] Preferably, the bending sleeve is made of a flexible and wear-resistant material, and a number of annular reinforcing ribs are fixedly fitted onto the outer surface of the bending sleeve, and the number of annular reinforcing ribs and the bending sleeve are integrally formed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model solves the problems of poor scratch resistance of the outer layer and easy compression of the inner core of existing computer cables by setting support strips on the outside of the base layer, with each support strip corresponding radially to the anti-scratch ridge. The support strips provide internal structural support, the anti-scratch ridge directly resists external scratches, and the flexible filler provides buffer protection. This significantly improves the scratch resistance and structural stability of computer cables.

[0015] 2. By setting up a bending sleeve, the bending sleeve can be precisely moved to the bending part of the computer cable and stably positioned by the guide groove that matches the anti-scratch edge on the inner side wall of the bending sleeve, as well as by its own flexible wear-resistant material and annular reinforcing ribs. This effectively disperses bending stress, reduces tensile damage at the bending part, avoids cracking of the outer layer and breakage of the inner core of the computer cable, and provides targeted protection for the bending area, further extending the service life of the computer cable.

[0027] 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.

[0028] like Figures 1 to 6 As shown, this utility model provides a scratch-resistant and wear-resistant outer layer structure for computer cables, including a computer cable body 1, which is composed of a base layer 11, a braided reinforcement layer 12, and a wear-resistant outer layer body 13.

[0029] The inner surface of the base layer 11 is provided with two intersecting partition plates 111, and the outer surface of the base layer 11 is provided with several support strips 115, with grooves 116 formed between adjacent support strips 115;

[0030] The braided reinforcement layer 12 is fitted on the outside of the base layer 11, and the inner side of the braided reinforcement layer 12 is provided with a snap strip 121 that is adapted to the groove 116;

[0031] The wear-resistant outer layer 13 covers the outside of the braided reinforcement layer 12. The outer surface of the wear-resistant outer layer 13 is provided with several anti-scratch ridges 131. Through the three-layer composite structure design of the base layer 11, the braided reinforcement layer 12 and the wear-resistant outer layer 13, combined with the support strip 115 on the outer surface of the base layer 11, the snap strip 121 of the braided reinforcement layer 12 and the anti-scratch ridges 131 of the wear-resistant outer layer 13, a comprehensive protection system is formed. This not only improves the overall structural strength of the computer cable body 1, but also directly resists external scratches through the anti-scratch ridges 131, effectively reducing the risk of damage to the outer layer.

[0032] Specifically, the two partition plates 111 are arranged in a cross shape, and the partition plates 111 and the base layer 11 are integrally molded. Both the partition plates 111 and the base layer 11 are made of modified nitrile rubber. The cross-shaped design not only stably separates the internal space, but also improves the deformation resistance of the base layer 11 by utilizing the elasticity and wear resistance of the modified nitrile rubber. At the same time, the integral molding structure reduces the connection gaps, preventing external forces from damaging the base layer 11 through the gaps and extending the service life of the base layer 11.

[0033] like Figures 1 to 6 As shown, the partition plate 111 and the inner surface of the base layer 11 enclose four independent receiving cavities 114. An inner core 112 is inserted into each receiving cavity 114. The partition plate 111 and the base layer 11 enclose four independent receiving cavities 114, so that each inner core 112 is placed separately, which effectively avoids the inner cores 112 from tangling and squeezing each other, ensuring the structural integrity of the inner core 112. At the same time, the independent space can reduce signal interference between the inner cores 112 and ensure the stability of data transmission.

[0034] Furthermore, the cavity 114 is filled with a flexible filler 113 made of flame-retardant foam. The flexible filler 113 wraps around the outer side of the inner core 112, and the flexible filler 113 is in close contact with the inner wall of the cavity 114 and the outer surface of the inner core 112. The flexible filler 113 made of flame-retardant foam tightly wraps around the inner core 112 and fits against the inner wall of the cavity 114. This can not only buffer external impact and prevent the inner core 112 from being damaged by compression, but also improve the safety performance of the computer cable body 1 by utilizing its flame-retardant properties. At the same time, the structure after filling can further fix the position of the inner core 112 and prevent it from shaking in the cavity 114.

[0035] like Figures 1 to 6 As shown, the anti-scratch ridges 131 are evenly distributed along the circumference of the wear-resistant outer layer body 13, and the number of anti-scratch ridges 131 is equal to the number of support strips 115. Each anti-scratch ridge 131 corresponds to each support strip 115 in the radial direction, so that the force on the wear-resistant outer layer body 13 is transmitted to the support strips 115 through the anti-scratch ridges 131, forming a support structure that echoes each other from top to bottom. This not only strengthens the deformation resistance of the wear-resistant outer layer body 13, but also makes the anti-scratch effect of the anti-scratch ridges 131 more stable, avoiding excessive local stress that could cause damage to the outer layer.

[0036] It is worth noting that a bending sleeve 2 is slidably fitted onto the outer surface of the wear-resistant outer layer body 13. The inner sidewall of the bending sleeve 2 is provided with a guide groove 22 that matches the anti-scratch ridge 131. The bending sleeve 2 is adapted to the anti-scratch ridge 131 of the wear-resistant outer layer body 13 through the guide groove 22, and can slide freely along the wear-resistant outer layer body 13. It can be accurately moved to the bending part of the computer cable body 1, specifically protecting the area that is easily damaged by repeated bending. At the same time, the cooperation between the guide groove 22 and the anti-scratch ridge 131 ensures that the bending sleeve 2 is positioned stably and avoids displacement during use.

[0037] like Figures 1 to 6 As shown, the bending sleeve 2 is made of flexible and wear-resistant material, and several annular reinforcing ribs 21 are fixedly sleeved on the outer surface of the bending sleeve 2. The several annular reinforcing ribs 21 and the bending sleeve 2 are integrally formed. The flexible and wear-resistant material of the bending sleeve 2 does not affect the normal bending of the computer cable body 1, and can resist the wear of the bending part. The integrally formed annular reinforcing ribs 21 further enhance the structural strength of the bending sleeve 2, effectively disperse the stress generated during bending, reduce fatigue damage at the bending part of the computer cable body 1, and extend the overall service life.

[0038] Working principle and process: The computer cable body 1 forms a three-layer protective structure consisting of a base layer 11, a braided reinforcement layer 12, and a wear-resistant outer body 13. The support strip 115 of the base layer 11 is adapted to the snap-fit ​​strip 121 of the braided reinforcement layer 12, achieving a stable connection between the base layer 11 and the braided reinforcement layer 12 and improving the overall structural strength. The anti-scratch ridge 131 of the wear-resistant outer body 13 corresponds radially to the support strip 115, enhancing its anti-scratch and anti-deformation capabilities. The partition plate 111 within the base layer 11 forms an independent receiving cavity 114, where the flexible filler 113 fixes and protects the inner core 112, preventing interference and compression. The bending sleeve 2, through the guide groove 22 and cooperation with the anti-scratch ridge 131, can slide to the bending part, dispersing bending stress with the assistance of the annular reinforcing rib 21, achieving targeted protection and comprehensively ensuring the performance and lifespan of the computer cable.
