Description

Technical Field

[0002] Fluoroplastic cable insulation sleeves are cable insulation materials made from fluoroplastics. They have excellent high temperature resistance, corrosion resistance, and aging resistance. Their characteristics include broad chemical stability, excellent electrical insulation and mechanical strength. They can work for a long time in extreme environments and are commonly used in high-requirement fields such as aerospace, chemical industry, and power industry. They are particularly suitable for electrical equipment under high temperature, high pressure and harsh conditions.

[0003] Fluoroplastic cable insulation sleeves are mainly composed of an outer fluoroplastic material, with an internal structure consisting of an insulation layer, a shielding layer, and a conductor layer. The insulation layer provides electrical insulation, the shielding layer prevents electromagnetic interference, and the conductor layer is responsible for current conduction. The working principle utilizes the high insulation and chemical corrosion resistance of fluoroplastics to ensure the cable operates normally in high-temperature, high-current, and corrosive environments, preventing electrical leakage and external interference, and improving the cable's stability and safety.

[0004] Existing fluoroplastic cable insulation sleeves can effectively protect the internal cables. However, during long-term storage, fluoroplastic cable insulation sleeves are prone to deformation due to external pressure and impact, which can damage the cables, affect their performance and effectiveness, and shorten their service life. Therefore, a new type of fluoroplastic cable insulation sleeve is proposed to solve the above problems. Utility Model Content

[0030] 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.

[0031] Example 1:

[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a fluoroplastic cable insulation sleeve, comprising a cable body 1, a protective component 2 installed on the outer layer of the cable body 1, a connecting pipe 3 slidably connected to the outer side of the protective component 2, and a pressure-resistant component 4 installed on the outer side of the connecting pipe 3; the pressure-resistant component 4 includes a fixing pipe 5, which is fixedly connected to the outer side of the connecting pipe 3, a sliding block 6 slidably connected inside the fixing pipe 5, and a pressure-resistant plate 7 fixedly connected to the outer side of the sliding block 6. When the pressure-resistant plate 7 is subjected to force, the pressure is relieved through the cooperation of the sliding block 6 and the fixing pipe 5. A buffer spring 8 is provided inside the fixing pipe 5, the diameter of the buffer spring 8 being smaller than the diameter of the sliding block 6. Through the support of the buffer spring 8, and in conjunction with the sliding block 6 and the fixing pipe 5, the pressure on the sleeve is relieved, preventing its deformation.

[0033] Reference Figure 1 and Figure 3The protection component 2 includes a buffer layer 201, which is disposed on the outside of the cable body 1. The buffer layer 201 is made of silicone material. The silicone material buffer layer 201 provides impact absorption, pressure relief and a certain degree of flexibility to prevent external impact and pressure from being transmitted to the inside of the sleeve.

[0034] Reference Figure 1 and Figure 2 A buffer pad 9 made of rubber is provided on the outer side of the pressure-resistant plate 7. The buffer pad 9 provides initial buffering of the pressure on the tube sleeve. A slider 10 is fixedly connected inside the connecting pipe 3. A groove 11 is provided on the outer side of the protective component 2. The slider 10 is slidably connected inside the groove 11. The position of the pressure-resistant component 4 can be freely adjusted by the cooperation of the slider 10 and the groove 11.

[0035] Example 2:

[0036] Reference Figure 3 In contrast to the above embodiments, this utility model also provides an embodiment in which the protective component 2 includes a tensile layer 202. The tensile layer 202 is disposed on the outside of the cable body 1. The tensile layer 202 is made of high-strength synthetic fiber material. The tensile layer 202 of high-strength synthetic fiber material provides the sleeve with tensile and tear resistance, ensuring that the sleeve will not break or deform excessively under tension, bending or external force.

[0037] Example 3:

[0038] Reference Figure 3 In contrast to the above embodiments, this utility model also provides an embodiment in which the protective component 2 includes a protective layer 203. The protective layer 203 is disposed on the outside of the cable body 1. The protective layer 203 is made of high-density polyethylene material. The high-density polyethylene material protective layer 203 provides the outermost physical protection to prevent damage to the sleeve from factors such as ultraviolet rays, oxidation, chemical corrosion, mechanical friction, and external scratches.

[0039] Example 4:

[0040] Reference Figure 3 In contrast to the above embodiments, this utility model also provides an embodiment in which the protective component 2 includes a buffer layer 201, a tensile layer 202, and a protective layer 203. The buffer layer 201 is disposed on the outside of the cable body 1, the tensile layer 202 is disposed on the outside of the buffer layer 201, and the protective layer 203 is disposed on the outside of the tensile layer 202. The buffer layer 201 is made of silicone material, the tensile layer 202 is made of high-strength synthetic fiber material, and the protective layer 203 is made of high-density polyethylene material. Through the cooperation of the outer protective layer 203, the middle tensile layer 202, and the inner buffer layer 201, the impact resistance, tensile strength, wear resistance, and aging resistance of the sheath can be effectively improved, thereby extending the service life of the cable.

[0041] Working principle: When the cable is placed, the anti-pressure component 4 is moved to a suitable position by the cooperation of the slider 10 and the groove 11. The pressure and impact force applied to the cable body 1 by the outside is first buffered by the buffer pad 9, and then the force is transmitted to the sliding block 6. With the cooperation of the buffer spring 8 and the fixing tube 5, the pressure is further relieved to prevent the cable body 1 from being deformed by the force and squeezing the internal cable.

[0042] The outer side of the cable body 1 is equipped with a multi-layer protective structure consisting of a protective layer 203, a tensile layer 202, and a buffer layer 201. The outer protective layer 203, with its wear-resistant, UV-resistant, and chemical corrosion-resistant properties, prevents environmental factors from damaging the bushing and ensures that the bushing can work stably for a long time in harsh environments. The middle tensile layer 202 enhances the bushing's tensile and tear resistance, effectively disperses external tensile and stress forces, and prevents the bushing from breaking under tension or pressure. The inner buffer layer 201 absorbs external impacts and pressures, reduces direct damage to the internal structure of the bushing from external forces, improves the bushing's mechanical strength and impact resistance, and extends the service life of the bushing.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
