Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite Teflon heat shrink tubing technology, specifically a multifunctional composite Teflon heat shrink tubing. Background Technology
[0002] Heat shrink tubing has extremely wide applications in modern industry and technology. From wire insulation and PCB protection in the electronics field, to fiber optic cable protection and repair in the communications field, and electrical equipment sealing and insulation in the power field, heat shrink tubing demonstrates its excellent physical and chemical properties. Furthermore, heat shrink tubing plays an important role in many industries such as automotive manufacturing, aerospace, construction, and railways, serving multiple functions including insulation, protection, marking, and sealing.
[0003] Existing heat shrink tubing has certain limitations in installation, especially after the wiring has been connected.
[0004] In practical use, because the heat shrink tubing needs to be inserted before the wiring is connected, this pre-installation method makes it very difficult to add heat shrink tubing after the wiring is connected. The space constraints that may occur after the wiring is connected, the irregularity of the wiring shape, and the performance degradation that may result from cutting the heat shrink tubing all make the installation of heat shrink tubing after the wiring is connected less effective.
[0005] Therefore, a multifunctional composite Teflon heat shrink tubing is needed to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a multifunctional composite Teflon heat shrink tubing to solve the problem mentioned in the background art that it is very difficult to add heat shrink tubing after the circuit connection.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional composite Teflon heat shrink tubing, comprising a heat shrink tubing body, the heat shrink tubing including a smooth heat shrink layer, a composite layer disposed on the inner side of the smooth heat shrink layer, a mesh reinforcing layer disposed inside the composite layer, a T-shaped mating hole disposed on the right side of the heat shrink tubing body, a mating strip disposed on the left side of the heat shrink tubing body, the mating strip being installed inside the mating hole, and a limit strip disposed on the outer side of the mating strip.
[0008] Preferably, the length of the mating hole is equal to the length of the mating strip.
[0009] Preferably, the length of the limiting strip is equal to that of the heat shrink tubing body.
[0010] Preferably, the smooth heat-shrinkable layer is made of polyolefin material, which shrinks axially after heating and has a smooth surface after shrinkage, exhibiting good wear resistance and weather resistance.
[0011] Preferably, the composite layer is a Teflon composite material, which provides excellent electrical properties and chemical stability, effectively resists the corrosion of chemical substances, and ensures safe use in harsh environments.
[0012] Preferably, the mesh reinforcement layer is made of polyester fiber, which improves its tensile, compressive and torsional resistance.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In actual use, the design of the T-shaped docking hole and the docking strip allows for easy addition of heat shrink tubing through segmented installation and docking after the wiring has been connected, effectively overcoming the difficulties of pre-installation; and the limiting strip ensures the stable installation of the docking strip. This heat shrink tubing not only improves installation flexibility but also enhances its applicability in complex and harsh environments. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Please see Figure 1-5This utility model provides a technical solution: a multifunctional composite Teflon heat shrink tubing, including a heat shrink tubing body 1, a smooth heat shrink layer 2, a composite layer 3 disposed inside the smooth heat shrink layer 2, a mesh reinforcement layer 4 disposed inside the composite layer 3, a T-shaped docking hole 5 disposed on the right side of the heat shrink tubing body 1, a docking strip 6 disposed on the left side of the heat shrink tubing body 1, the docking strip 6 being installed inside the docking hole 5, and a limit strip 7 disposed on the outside of the docking strip 6. The heat shrink tubing body 1 contains the main structural and functional parts of the heat shrink tubing; the composite layer 3 is located inside the smooth heat shrink layer 2 and is used to enhance the performance and durability of the heat shrink tubing; the mesh reinforcement layer 4 is located inside the composite layer 3 and is a mesh structure that increases the strength and durability of the heat shrink tubing, making it more able to withstand external forces such as tension, torsion, and compression.
[0022] The length of the mating hole 5 is equal to the length of the mating strip 6, which allows the two to fit tightly when connected, effectively preventing the influence of the external environment on the circuit and improving the insulation effect and protection performance. At the same time, this design also makes the heat shrink tubing more aesthetically pleasing and neat after installation, improving the overall user experience.
[0023] The length of the limiting strip 7 is equal to that of the heat shrink tubing body 1. The matching of the length of the limiting strip 7 and the heat shrink tubing body 1 makes the entire heat shrink tubing look more unified and coordinated. There is no excess length or exposed part, which not only improves the overall aesthetics of the product, but also makes the heat shrink tubing look neater and more professional after installation.
[0024] The smooth heat-shrinkable layer 2 is made of polyolefin material. This material shrinks axially after heating, and the surface is smooth after shrinkage, with good wear resistance and weather resistance.
[0025] Composite layer 3 is a Teflon composite material. Teflon composite material provides excellent electrical properties and chemical stability, effectively resists the corrosion of chemical substances, and ensures safe use in harsh environments.
[0026] The mesh reinforcement layer 4 is made of polyester fiber, which improves its tensile, compressive and torsional resistance.
[0027] As an embodiment of this utility model: when using the multifunctional composite Teflon heat shrink tubing, the composite layer 3 is located inside the smooth heat shrink layer 2 to enhance the performance and durability of the heat shrink tubing. The mesh reinforcement layer 4 is located inside the composite layer 3 and is a mesh structure that increases the strength and durability of the heat shrink tubing, making it more able to withstand external forces such as tension, torsion, and compression. The design of the T-shaped mating hole 5 and the mating strip 6 allows for easy addition of heat shrink tubing after the wiring has been connected, through segmented installation and mating, effectively overcoming the difficulties of pre-installation. Furthermore, the limiting strip 7 ensures the stable installation of the mating strip 6. This type of heat shrink tubing not only improves installation flexibility but also enhances its applicability in complex and harsh environments.
