Description

Technical Field

[0001] The utility model relates to the technical field of sheathed wires, and particularly relates to a special-shaped compression-resistant sheathed wire. Background Art

[0002] In the fields of modern communication and power transmission, sheathed wires, as important infrastructure, play a key role in protecting the internal cable cores and ensuring the stability of signal and power transmission. With the continuous progress of technology and the increasingly complex application environment, the performance requirements for sheathed wires are also getting higher and higher. Traditional sheathed wires usually adopt a circular or flat cross-sectional design. Although this design meets the basic protection requirements to a certain extent, its compression resistance and stability are often insufficient when facing complex external pressures and environmental challenges.

[0003] Deficiencies of Existing Sheathed Wires

[0004] Limited compression resistance: When traditional circular or flat cross-sectional sheathed wires are subjected to external pressure, local stress concentration is likely to occur, resulting in deformation or damage of the sheathed wire and affecting its compression resistance. This design cannot effectively disperse the pressure, challenging the stability of the sheathed wire in complex environments.

[0005] Unstable cable core positioning: The positioning of the cable core inside the existing sheathed wire is usually relatively simple, lacking effective fixing and supporting structures. When subjected to external forces, the cable core is prone to shift, affecting the stability and reliability of the transmission performance.

[0006] Insufficient internal structural compactness: There are often large gaps inside traditional sheathed wires, which not only reduce the structural compactness but also may cause unnecessary movement and friction of the internal cable cores when subjected to external forces, affecting their service life and performance.

[0007] Therefore, this solution particularly proposes a special-shaped compression-resistant sheathed wire to solve the above problems. Content of the Utility Model

[0008] To overcome the defects of the prior art, the purpose of the utility model is to provide a special-shaped compression-resistant sheathed wire.

[0009] To achieve the above object, the technical solution of the utility model is realized as follows: A special-shaped compression-resistant sheathed wire includes an outer protective sleeve and a cable core. The outer frame of the overall cross-section of the outer protective sleeve is set as an isosceles trapezoid. Inside the outer protective sleeve, at the center of the bottom of its internal isosceles trapezoidal cavity, there is a cable core positioning strip with a rectangular cross-section. The cable cores are evenly distributed inside the cable core positioning strip. On both left and right sides of the internal isosceles trapezoidal cavity of the outer protective sleeve, there are side positioning strips positioned on the left and right sides of the cable core positioning strip. Inside the internal cavity of the outer protective sleeve, a top elastic filling member is arranged in the space formed between the cable core positioning strip and the two side positioning strips on both sides.

[0010] Preferably, the cable core positioning strip is integrally made of pp fiber material, and a shaping sleeve is arranged on the outer side of the cable core positioning strip.

[0011] Preferably, the shaping sleeve is integrally made of silicone rubber material.

[0012] Preferably, the side positioning strip is integrally made of natural rubber material.

[0013] Preferably, the top elastic filling member specifically includes the following structure:

[0014] An elastic filling frame filled in the space between the inner part of the outer protective sleeve, the two side positioning strips and the top of the cable core positioning strip;

[0015] A plurality of elastic support ribs uniformly distributed inside the elastic filling frame;

[0016] A filling material filled in the elastic filling frame.

[0017] Preferably, the outer protective sleeve is made of polyvinyl chloride material.

[0018] Preferably, the elastic filling frame is made of silica gel material.

[0019] Preferably, the elastic support ribs are made of high-elastic rubber material.

[0020] Preferably, the filling material is made of pp fiber.

[0021] The beneficial effects of the present utility model are embodied in:

[0022] Enhanced compressive performance: By designing the outer protective sleeve as an isosceles trapezoid cross-section, not only the cross-sectional area of the sheathed wire is increased, but also its stress distribution is optimized, thus significantly improving the compressive strength. This shape design enables the sheathed wire to more evenly disperse the pressure when subjected to external pressure, reduces local stress concentration, and enhances the overall compressive capacity.

[0023] Stable cable core positioning: The arrangement of the cable core positioning strip and the side positioning strip ensures the position stability of the cable core inside the sheathed wire. This structural design effectively prevents the cable core from shifting when subjected to external forces, ensuring the stability and reliability of the transmission performance.

[0024] Optimized internal structure: The introduction of the top elastic filling member not only fills the voids inside the sheathed wire, improves the structural compactness, but also absorbs and reduces the impact of external pressure on the cable core through its elasticity and buffering performance. This design further enhances the compressive performance and recovery ability of the sheathed wire.

[0025] Optimization of material selection: High-performance materials such as PP fibers, silicone rubber, natural rubber, and polyvinyl chloride are used, which not only improve the mechanical strength and insulation performance of each component but also enhance the overall wear resistance, anti-aging property, and flame retardancy. The combination and optimized arrangement of these materials ensure the stability and durability of the sheathed wire in various complex environments.

[0026] In summary, through its unique isosceles trapezoidal outer protective sleeve design and the optimization of the internal structure, this special-shaped compression-resistant sheathed wire achieves excellent compression resistance. The isosceles trapezoidal cross-section of the outer protective sleeve not only increases the cross-sectional area but also optimizes the force distribution, enabling the sheathed wire to disperse the external pressure more evenly when under external pressure, reducing local stress concentration, and thus significantly improving the overall compression resistance. The optimization of the internal structure, including the design of the cable core positioning strip, side positioning strip, and top elastic filling member, ensures the stability of the cable core and the reliability of the transmission performance. At the same time, through the optimized selection of materials, the wear resistance, anti-aging property, and flame retardancy of the sheathed wire are further enhanced. These designs and material selections enable the sheathed wire to maintain excellent performance in various complex usage environments and meet the requirements for high-performance sheathed wires in the modern communication and power transmission fields.

[0039] Please refer to the attached specification Figures 1-4 , the present utility model provides a special-shaped compression-resistant sheathed wire, including an outer protective sleeve (1) and a cable core (3). The outer frame of the overall cross-section of the outer protective sleeve (1) is set as an isosceles trapezoid, and the specific shape is as Figure 1 shown. This design of the isosceles trapezoid not only increases the cross-sectional area of the sheathed wire and improves its compressive strength. A cable core positioning strip (2) with a rectangular cross-section is arranged at the center of the bottom inside the isosceles trapezoid cavity of the outer protective sleeve (1). The arrangement of the cable core positioning strip (2) can effectively prevent the cable core (3) from shifting inside the sheathed wire, ensuring the stability and transmission performance of the cable core (3). The cable core (3) is evenly distributed inside the cable core positioning strip (2).

[0040] Side positioning strips (4) positioned on the left and right sides of the cable core positioning strip (2) are arranged on both the left and right sides of the isosceles trapezoid cavity inside the outer protective sleeve (1) to further ensure the stability of the cable core (3) and prevent it from shifting when subjected to external forces. A top elastic filling member (5) is arranged inside the cavity of the outer protective sleeve (1) in the space formed between the cable core positioning strip (2) and the side positioning strips (4) on both sides. The top elastic filling member (5) can not only fill the voids inside the sheathed wire and improve the compactness of its structure, but also absorb and buffer the influence of external forces on the cable core (3), further enhancing the compressive performance of the sheathed wire.

[0041] Embodiment 2

[0042] Based on the above-mentioned Embodiment 1, the cable core positioning strip (2) is entirely made of PP fiber material, and a shaping sleeve (21) is arranged on the outer side of the cable core positioning strip (2). The PP fiber material has excellent insulation performance and mechanical strength, which can effectively isolate the interference between the cable cores (3) and improve the compressive resistance of the cable core positioning strip (2) at the same time. The shaping sleeve (21) is entirely made of silicone rubber material, which can not only protect the cable core positioning strip (2) from being worn or damaged, but also further enhance the compressive performance and shaping effect of the cable core positioning strip (2), enabling it to maintain a stable shape and position for a long time.

[0043] Embodiment 3

[0044] Based on Embodiment 1, the side positioning strip (4) is entirely made of natural rubber material. Natural rubber has excellent elasticity and flexibility, which can effectively absorb and buffer the influence of external forces on the sheathed wire, further improving the compressive performance of the sheathed wire. At the same time, natural rubber also has good insulation performance and wear resistance, which can protect the cable core (3) from damage for a long time and extend the service life of the sheathed wire.

[0045] Embodiment 4

[0046] Based on Embodiment 1, the top elastic filling member (5) includes the following structure:

[0047] An elastic filling frame (51) filled in the space between the inner part of the outer protective sleeve (1), the two side positioning strips (4) and the top of the cable core positioning strip (2), as Figure 4 shown. The elastic filling frame (51) is made of silicone material and has excellent elasticity and resilience, which can effectively absorb and buffer the influence of external forces on the sheathed wire and improve its compressive resistance.

[0048] A number of elastic support ribs (53) evenly distributed inside the elastic filling frame (51). The elastic support ribs (53) are made of high-elastic rubber material, which can not only improve the support strength of the elastic filling frame (51) and prevent it from deforming or collapsing when stressed, but also further enhance the compressive performance and recovery ability of the sheathed wire.

[0049] A filling material (52) filled in the elastic filling frame (51). The filling material (52) is made of PP fiber, which can not only fill the voids inside the elastic filling frame (51) and improve the compactness of its structure, but also absorb and buffer the influence of external forces on the cable core (3) and further enhance the compressive performance of the sheathed wire.

[0050] Through the combination and optimized arrangement of various materials, the above structure not only greatly improves the compressive capacity of the sheathed wire, but also ensures its elasticity and recovery ability under stress, enabling it to adapt to various complex usage environments.

[0051] Example 5

[0052] On the basis of Example 1, the outer protective sleeve (1) is made of polyvinyl chloride material. Polyvinyl chloride material not only has excellent wear resistance and anti-aging performance, which can protect the internal structure of the sheathed wire from damage for a long time, but also has good flame retardant performance and electrical insulation performance, which can improve the safety and stability of the sheathed wire. At the same time, polyvinyl chloride material also has excellent processing performance, which is convenient for the production and manufacture of the sheathed wire and reduces the production cost.

[0053] Through the description of the above specific implementation manners, it can be seen that the present invention has been comprehensively optimized and innovated in structural design, not only greatly improving the compressive performance and reliability of the sheathed wire, but also taking into account its flexibility and ease of installation.
