Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing technology, specifically to a series of heat shrink tubing. Background Technology

[0002] Heat shrink tubing is a tubular insulating and protective material made of polymer materials such as polyolefins and fluoroplastics. It has the property of shrinking when heated. After heating, it can tightly wrap around the surface of objects such as wires and cables, wire harnesses, solder joints, and inductors to form an insulating and sealed protective layer. It can effectively prevent electrical faults such as leakage and short circuits, while resisting external damage such as moisture, dust, oil, chemical corrosion and mechanical wear. It is widely used in electronics, power, communications, automotive, aerospace and other fields.

[0003] Existing heat shrink tubing is a single product, which needs to be threaded onto the wire harness or cable one by one. When the working space is small, the repeated operation is time-consuming and laborious, which is not conducive to the organization and maintenance of the line. In addition, the shrinkage degree and tightness of each heat shrink tubing are different, which can easily lead to moisture, dust and other substances entering through the gaps.

[0011] As a further description of the above technical solution, the top of the main body is provided with an arc-shaped part, which is used to fit the gripping surface.

[0012] As a further description of the above technical solution, the radius of curvature of the arc-shaped part is 5-8 times the radius of the heat shrink tubing.

[0017] 1. The heat shrink tubing in this utility model is an assembly of multiple heat shrink tubing connected in parallel, made of polymer material.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figures 1-2 As shown, in one embodiment, a row of heat shrink tubing includes: an extruded tube preform 1 integrally formed by a shaped extrusion die, and the interior of the extruded tube preform 1 is covered with multiple sets of parallel heat shrink tubing 2, which not only ensures the integrity and stability of the product, but also significantly improves production efficiency and reduces the deviation problems that may occur when assembling a traditional single heat shrink tubing 2.

[0026] The extruded tube blank 1 includes a main body 11, and the heat shrink tube 2 is arranged parallel to each other at equal intervals within the main body 11. This ensures that the heat shrink tube 2 can be subjected to uniform force when heated and shrinking, avoiding the protection failure caused by uneven local shrinkage. It also allows the entire row of heat shrink tubes 2 to achieve a tight fit when wrapping wire harnesses or cables, effectively preventing the intrusion of external impurities.

[0027] Specifically, the heat shrink tubing 2 has 2-8 sets, and the appropriate number of sets can be selected according to the actual wiring needs; the diameter of the heat shrink tubing 2 is 8-30mm, and a suitable specification can be found for both thinner electronic circuits and thicker power cables; the shrink ratio of the heat shrink tubing 2 is 2:1, and after being heated and shrunk, the heat shrink tubing 2 can tightly wrap around the outside of the cable, providing excellent insulation protection while ensuring that there are no gaps between the protective layer and the object, so as to achieve the best protection effect.

[0028] Understandably, the heat shrink tubing 2 is an assembly of multiple parallel heat shrink tubing 2 made of polymer material, which can form a continuous and sealed overall protection; it can effectively isolate mutual interference between cables, greatly reducing the probability of faults such as leakage and short circuit; and it can resist the corrosion of external impurities in complex environments such as humidity, dust, and oil, protecting the safety of internal circuits; in addition, it can save a lot of installation space, reduce the overall weight, make the wiring layout more concise and orderly, and facilitate the later wiring organization and maintenance work.

[0029] For example, the extruded tube preform 1 material can be flexibly produced using rigid or semi-rigid materials depending on the specific application scenario: when applied to scenarios with high requirements for strength and rigidity (such as internal wiring protection of industrial equipment, wiring of power distribution cabinets, etc.), a combination of low-density polyethylene (LDPE) and flame-retardant materials can be selected. This rigid material not only has excellent mechanical strength and can withstand certain external extrusion and friction, but also has good flame-retardant properties, effectively improving the safety of use; while in scenarios with special requirements for flexibility and weather resistance (such as internal wiring of automobiles, wiring of outdoor communication equipment, etc.), a combination of low-density polyethylene (LDPE), ethylene-ethyl acrylate copolymer (VEA) and flame retardant is used. This semi-rigid material, while ensuring a certain rigidity, has better flexibility and aging resistance, can adapt to complex installation environments and changing climatic conditions, and takes into account both aesthetics and practicality, meeting the wiring needs of various scenarios.

[0030] Furthermore, the top of the main body 11 is provided with an arc-shaped portion 12 to ensure that it naturally conforms to the gripping surface of the operator's fingers during installation. This design not only effectively reduces hand fatigue during installation but also provides a more stable grip when threading the heat shrink tubing 2, avoiding installation errors caused by slippage and significantly improving construction efficiency. Specifically, the radius of curvature of the arc-shaped portion 12 is 5-8 times the radius of the heat shrink tubing 2.

[0031] Furthermore, the main body 11 has symmetrically arranged extension portions 13 on both sides. By punching holes in the extension portions 13, various fasteners such as cable ties and screws can be used to firmly fix the heat shrink tubing 2 to the equipment or line, effectively preventing the heat shrink tubing 2 from shifting or falling off during use. Specifically, the length of the extension portion 13 is 1-2 cm, and the thickness of the extension portion 13 is 1-2 mm.

[0032] Through the above technical solution, this application can form a continuous and closed overall protection, which can effectively prevent leakage and short circuit, resist external impurities and other corrosion, save installation space, reduce overall weight, and facilitate the arrangement and maintenance of the line.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
