Description
Technical Field
[0001] The present application relates to the technical field of polyvinyl chloride sheathed flexible wires, and in particular to a wear-resistant and high-toughness polyvinyl chloride sheathed flexible wire. Background Art
[0002] With the development of society, the application of PVC-sheathed flexible cables is becoming increasingly widespread across various fields. PVC-sheathed flexible cables are a commonly used type of wire and cable. They offer excellent flexibility and conductivity, making them widely used in a wide range of applications, including household appliances, industrial equipment, and communications facilities. PVC-sheathed flexible cables not only transmit power and signals but also provide stable energy support for various devices, ensuring their normal operation. Their excellent flexibility allows for flexible routing in diverse environments and adapts to a variety of complex installation conditions.
[0003] However, existing PVC-sheathed flexible cables present several problems. For one thing, existing PVC-sheathed flexible cables suffer from poor wear resistance during use. Because the flexible cables may be frequently subjected to external forces such as friction and scratching during use, their outer coverings can easily wear out, exposing the internal conductors. This not only impacts the service life of the cables but can also pose a safety hazard. Furthermore, in practical applications, it is often necessary to connect two or more flexible cables together, but existing connection methods are often complex, time-consuming, and labor-intensive, and the stability and reliability of the connections after connection are difficult to guarantee. Summary of the Invention
[0004] The purpose of this application is to have wear resistance and high temperature resistance to extend service life, and to be able to connect quickly, improve work efficiency and ensure connection stability.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a wear-resistant and high-toughness polyvinyl chloride sheathed flexible cable, comprising a flexible cable body, a copper core fixedly installed inside the flexible cable body, a connecting collar movably installed on the top of the flexible cable body, an inner wall of the connecting collar having an internal thread, an outer wall of the bottom of the flexible cable body having an external thread, and a limit assembly installed between the two flexible cable bodies;
[0006] The limiting assembly includes a limiting block and a limiting groove. The limiting block has multiple ring-shaped fixed connections to the bottom outer wall of the flexible wire body. The limiting groove has multiple ring-shaped openings on the top of the flexible wire body. The limiting block is located inside the limiting groove.
[0007] As a preferred embodiment, the flexible wire body includes a wear-resistant sheath, a polyvinyl chloride insulating sheath and a silicone rubber heat-resistant sheath. The wear-resistant sheath is located on the outer layer of the flexible wire body, the polyvinyl chloride insulating sheath is fixedly installed inside the wear-resistant sheath, and the silicone rubber heat-resistant sheath is fixedly installed inside the polyvinyl chloride insulating sheath.
[0008] As another preferred embodiment, the copper core is fixedly installed inside the silicone rubber temperature-resistant sleeve.
[0009] Further preferably, a clamping ring is provided on the top of the flexible wire body, and a movable ring is provided on the bottom of the connecting ring, and the movable ring is located inside the clamping ring.
[0010] Further preferably, reinforcing ribs are fixedly installed inside the cord body, and there are multiple reinforcing ribs, which are distributed in a ring shape.
[0011] Further preferably, the outer wall of the connecting collar is provided with anti-slip grooves, and there are multiple anti-slip grooves, which are distributed in a ring shape.
[0012] Compared with the prior art, the present invention has the following advantages:
[0013] (1) Compared with the existing technology, by setting the wear-resistant sheath, polyvinyl chloride insulation sleeve, silicone rubber heat-resistant sleeve and copper core, when in use, the wear-resistant sheath is in direct contact with the outside world, and is subjected to various frictions and scratches, effectively protecting the internal structure. The polyvinyl chloride insulation sleeve plays an insulating role to prevent current leakage. The silicone rubber heat-resistant sleeve can withstand higher temperatures. When the soft wire is in a high-temperature environment, it can protect the internal copper core from being affected by high temperatures. This utility model can extend the service life of the soft wire, improve its reliability in high-temperature environments, and reduce failures caused by wear and high temperatures.
[0014] (2) Compared with the prior art, by providing a flexible wire body, a connecting collar, an internal thread, an external thread, a limiting block, and a limiting groove, when connecting the flexible wire bodies, the limiting block at the bottom of one flexible wire body is aligned and inserted into the limiting groove at the top of the other flexible wire body to achieve preliminary positioning, and then the connecting collar is put on the bottom of one flexible wire body. Then, by rotating the connecting collar, the internal thread on the inner wall of the connecting collar and the external thread on the outer wall of the bottom of the flexible wire body are used to tighten. The utility model can make flexible wire connection more convenient and quick, improve work efficiency, and at the same time ensure the stability and reliability of the connection.

[0024] like Figure 1-4The shown embodiment is a wear-resistant and high-toughness polyvinyl chloride sheathed flexible cable, comprising a flexible cable body 1, a copper core 104 being fixedly installed inside the flexible cable body 1, a connecting ring 2 being movably installed on the top of the flexible cable body 1, an inner wall of the connecting ring 2 being provided with an inner thread 5, an outer wall of the bottom of the flexible cable body 1 being provided with an outer thread 6, and a limiting assembly 7 being installed between the two flexible cable bodies 1; the limiting assembly 7 comprises a limiting block 701 and a limiting groove 702, the limiting block 701 having a plurality of annular portions fixedly connected to the bottom outer wall of the flexible cable body 1, the limiting groove 702 having a plurality of annular portions opened on the top of the flexible cable body 1, and the limiting block 701 being located inside the limiting groove 702.
[0025] When two flexible wires need to be connected, the limiting block 701 at the bottom of one flexible wire body 1 is inserted into the limiting groove 702 at the top of the other flexible wire body 1. This allows the two flexible wires to be preliminarily positioned. Then, the connecting ring 2 is rotated. At this time, the two flexible wire bodies 1 can be firmly connected and fixed together through the cooperation of the external thread 6 and the internal thread 5, thereby improving the accuracy and stability of the flexible wire connection.
[0026] The flexible wire body 1 includes a wear-resistant sheath 101, a polyvinyl chloride insulating sheath 102 and a silicone rubber heat-resistant sheath 103. The wear-resistant sheath 101 is located on the outer layer of the flexible wire body 1, the polyvinyl chloride insulating sheath 102 is fixedly installed inside the wear-resistant sheath 101, and the silicone rubber heat-resistant sheath 103 is fixedly installed inside the polyvinyl chloride insulating sheath 102.
[0027] The wear-resistant sheath 101 is in direct contact with the outside world, withstands various frictions and scratches, and effectively protects the internal structure; the polyvinyl chloride insulation sheath 102 plays an insulating role to prevent current leakage; the silicone rubber heat-resistant sheath 103 can withstand higher temperatures and protect the internal copper core 104 from being affected by high temperatures when the soft wire is in a high temperature environment.
[0028] The copper core 104 is fixedly installed inside the silicone rubber temperature-resistant sleeve 103 .
[0029] The copper core 104 is the main carrier of the flexible wire for transmitting current and signals. It is wrapped and protected by the silicone rubber temperature-resistant sleeve 103 to ensure stable transmission of current and signals and the conductive performance of the flexible wire. At the same time, it provides good protection for the copper core 104 and reduces interference from external factors.
[0030] A clamping ring 3 is provided on the top of the cord body 1 , and a movable ring 4 is provided on the bottom of the connecting ring 2 . The movable ring 4 is located inside the clamping ring 3 .
[0031] When connecting the cord, the connecting ring 2 is put on the top of the cord body 1, and the movable ring 4 is clamped into the clamping ring 3, so that the connecting ring 2 can be rotated on the top of the cord body 1, which is convenient for subsequent tightening and connection operations.
[0032] A plurality of reinforcing ribs 8 are fixedly installed inside the cord body 1 , and the plurality of reinforcing ribs 8 are distributed in a ring shape.
[0033] The reinforcing ribs 8 can enhance the structural strength of the cord body 1 , preventing the cord from being excessively deformed or damaged when pulled or bent by external forces, thereby making the cord more durable.
[0034] The outer wall of the connecting collar 2 is provided with anti-slip grooves 201 . There are multiple anti-slip grooves 201 , and the multiple anti-slip grooves 201 are distributed in a ring shape.
[0035] When rotating the connecting ring 2 , the anti-slip grooves 201 can increase friction, prevent the hand from slipping, and facilitate tightening the connecting ring 2 .
[0036] Working Principle: First, align and insert the stopper 701 on the bottom of one cable body 1 into the stopper groove 702 on the top of the other cable body 1 to achieve preliminary positioning. Then, insert the connecting collar 2 onto the bottom of one of the cable bodies 1. Next, rotate the connecting collar 2, tightening it by interlocking the internal threads 5 on the inner wall of the connecting collar 2 with the external threads 6 on the outer wall of the bottom of the cable body 1. During this process, the anti-slip grooves 201 prevent your hand from slipping, making the operation smoother.
[0037] During daily use, the wear-resistant outer sheath 101 of the cord body 1 withstands external friction and scratches, while protecting the internal PVC insulation sleeve 102, silicone rubber heat-resistant sleeve 103, and copper core 104. The PVC insulation sleeve 102 ensures stable current transmission within the cord, preventing leakage. The silicone rubber heat-resistant sleeve 103 provides heat resistance when the cord is exposed to high temperatures, protecting the copper core 104. The reinforcing ribs 8 within the cord body 1 enhance the cord's structural strength, allowing it to withstand certain external forces without damage.
