Technical Field
[0001] This utility model relates to the field of communication engineering, and in particular to a polyvinyl chloride hinged connection cable. Background Technology
[0002] In power and electronic systems, cables are key components for the transmission of electrical energy and signals. Their performance and lifespan directly affect the stability and reliability of the entire system. Although traditional PVC stranded cables have a wide range of applications, they still have shortcomings in terms of bending resistance, waterproof and sun protection capabilities, and service life under certain specific environments.
[0003] Existing PVC stranded cables are mainly composed of multiple single copper wires twisted together, with the outer surface of the cable being made of PVC. However, during cable installation or in complex environments, excessive bending of the cable may cause deformation of the internal conductor and damage to the insulation layer, thereby affecting the electrical performance and mechanical strength of the cable. At the same time, the cable is usually exposed on the surface, and in humid or variable outdoor environments, the cable sheath is easily corroded, resulting in decreased insulation performance and shortening the cable's service life.
[0004] Therefore, it is necessary to design a PVC hinged cable that can protect the cable from bending, prevent damage and breakage caused by excessive bending, and also waterproof and sun-proof the cable surface to extend the cable's service life. Utility Model Content
[0005] To overcome the shortcomings of existing PVC stranded connection cables, such as the potential deformation of internal conductors and damage to the insulation layer due to excessive bending, which affects the electrical performance and mechanical strength of the cable, and the fact that the cable is usually exposed to the surface and its outer sheath is easily corroded in humid or variable outdoor environments, resulting in decreased insulation performance and shortened cable life, this invention provides a PVC stranded connection cable that can protect the cable from bending, prevent damage and breakage caused by excessive bending, and waterproof and sun-proof the cable surface, thus extending the cable's service life.
[0006] The technical implementation scheme of this utility model is as follows: a polyvinyl chloride hinged connection cable includes a battery core, an insulating protective layer, a waterproof layer, a protective mesh, a polyvinyl chloride outer layer, sliding rings, a corrugated tube, and an anti-bending frame. The battery core has two parts, front and rear, and an insulating protective layer is connected to the outer side of each battery core. A waterproof layer is connected between the outer sides of the insulating protective layers. A protective mesh is connected to the outer side of the waterproof layer. A polyvinyl chloride outer layer is connected to the outer side of the protective mesh. The polyvinyl chloride outer layer is placed inside the corrugated tube. Sliding rings are connected to both the left and right sides of the corrugated tube. An anti-bending frame is connected to the side of the sliding rings that are far apart from each other.
[0007] Alternatively, the protective netting may be made of metal.
[0008] Optionally, the anti-bend frame has a flared structure.
[0009] Optionally, it also includes an inlet pipe and an outlet pipe, with the inlet pipe connected to the upper side of the sliding ring near the right side of the corrugated pipe and the outlet pipe connected to the lower side of the sliding ring near the left side of the corrugated pipe.
[0010] Optionally, it also includes a first splicing block, a second splicing block, and connecting bolts. The first splicing block is connected to both the front and rear sides of the sliding ring near the left side of the bellows, and the second splicing block is connected to both the front and rear sides of the sliding ring near the right side of the bellows. Each of the second splicing blocks is provided with a connecting bolt.
[0011] Optionally, each of the first splicing blocks has a mating hole.
[0012] This utility model has the following advantages:
[0013] 1. This utility model uses a corrugated pipe to waterproof and protect the outer layer of polyvinyl chloride from the sun. When the cable is bent, the outer layer of polyvinyl chloride on the cable will come into contact with the anti-bending frame. The anti-bending frame limits the cable, thus achieving the effect of protecting the cable from bending and preventing damage and breakage caused by excessive bending. It also waterproofs and protects the cable surface from the sun, extending the service life of the cable.
[0014] 2. This utility model splices the corrugated pipe according to the length of the cable, so that the first splicing block and the second splicing block are in contact. Then, the connecting bolts are passed through the mating holes and the first splicing block and the second splicing block are fixed by the connecting bolts. This achieves the effect of splicing the corrugated pipe according to the length of the cable, which is convenient for different use needs.
[0015] 3. This utility model uses an external water source connected to the water inlet pipe to allow water to enter the corrugated pipe and cool the cable through the water source, thus achieving the effect of cooling the cable and preventing damage caused by excessive cable temperature.

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0022] A type of PVC hinged cable, such as Figures 1-4 As shown, the system includes a battery cell 1, an insulating protective layer 2, a waterproof layer 3, a protective mesh 4, a polyvinyl chloride (PVC) outer layer 5, a sliding ring 6, a water inlet pipe 7, a water outlet pipe 8, a corrugated pipe 9, an anti-bending frame 10, a first splicing block 11, a second splicing block 12, and connecting bolts 13. The battery cell 1 has two sections, front and rear. An insulating protective layer 2 is connected to the outer side of each battery cell 1. A waterproof layer 3 is connected between the outer sides of the insulating protective layers 2. A protective mesh 4, made of metal, is connected to the outer side of the waterproof layer 3. A PVC outer layer 5 is connected to the outer side of the protective mesh 4 and is placed inside the corrugated pipe 9. Sliding rings 6 are connected to both the left and right sides of the pipe 9. A water inlet pipe 7 is connected to the upper side of the sliding ring 6 near the right side of the corrugated pipe 9, and a water outlet pipe 8 is connected to the lower side of the sliding ring 6 near the left side of the corrugated pipe 9. Anti-bending brackets 10 are connected to the sides of the sliding rings 6 that are far apart from each other. The anti-bending brackets 10 have a flared structure to facilitate bending. First splicing blocks 11 are connected to both the front and rear sides of the sliding ring 6 near the left side of the corrugated pipe 9. The first splicing blocks 11 have mating holes to facilitate mating and installation. Second splicing blocks 12 are connected to both the front and rear sides of the sliding ring 6 near the right side of the corrugated pipe 9. Connecting bolts 13 are provided on the second splicing blocks 12.
[0023] When using this device, first place it in the cable installation area. Then, place the sequentially wrapped battery core 1, insulation protective layer 2, waterproof layer 3, protective mesh 4, and polyethylene outer layer 5 inside the corrugated pipe 9. Next, move the sliding ring 6 outward to extend the corrugated pipe 9. Then, splice the corrugated pipe 9 according to the cable length, so that the first splicing block 11 contacts the second splicing block 12. Then, pass the connecting bolt 13 through the mating hole and fix the first splicing block 11 and the second splicing block 12 with the connecting bolt 13. This allows the corrugated pipe 9 to be spliced according to the cable length, facilitating different usage needs. Afterward, the corrugated pipe 9 provides waterproofing and sun protection for the polyethylene outer layer 5. When the cable bends during installation or due to other factors, it will cause the cable to... The outer polyvinyl chloride layer 5 contacts the anti-bending frame 10, which limits the cable and prevents excessive bending. At the same time, when the cable bends, the protective mesh 4 protects the waterproof layer 3 and the insulation protective layer 2, preventing the surfaces of the waterproof layer 3 and the insulation protective layer 2 from cracking. The protective mesh 4 is made of metal and can shield electromagnetic signals, thus providing anti-bending protection for the cable and preventing damage and breakage caused by excessive bending. It can also waterproof and protect the cable surface from the sun, extending the cable's service life. When the weather is too hot, water is connected to an external water source through the water inlet pipe 7, allowing water to enter the corrugated pipe 9 to cool the cable, thus preventing damage caused by excessive cable temperature. When cooling is needed, the water can be discharged from the water outlet pipe 8.
[0024] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
