Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a cable protection tube that is anti-interference and anti-static. Background Technology

[0002] Chinese Patent CN223079735U, authorized by patent announcement number CN223079735U, discloses an anti-interference and anti-static cable protection pipe, relating to the field of cable-related technology. This utility model includes a pipe body, a base plate, and a grid frame. The pipe body comprises, from the outside to the inside, a pressure-resistant protective outer pipe, an electromagnetic shielding middle layer pipe, and an insulating inner pipe. A horizontal plate is fixed inside the insulating inner pipe, and base plates are fixed to the upper and lower surfaces of the horizontal plate. A ground wire is fixedly connected to the side of each base plate, and a grid frame is fixed to the ends of the opposite sides of the two base plates. This utility model, by setting up the pressure-resistant protective outer pipe, electromagnetic shielding middle layer pipe, base plate, ground wire, insulating inner pipe, horizontal plate, and grid frame, solves the problems of insufficient anti-interference and pressure resistance, the need to improve anti-static capabilities, and the mutual interference and insufficient heat dissipation when laying communication cables and power cables inside the cable protection pipe.

[0003] However, the above technical solution still has the following shortcomings in actual use. Although the ground wire connected to the side of the substrate of the device can discharge static electricity, the ground wire joint is prone to poor contact due to electrochemical corrosion in damp soil or groundwater, which leads to the interruption of the static electricity discharge channel. When multiple cables in the tube generate static electricity at the same time, the static electricity is prone to accumulate locally, and there is still a risk of breaking down the insulation layer. Therefore, we propose an anti-interference and anti-static cable protection tube to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-interference and anti-static cable protection tube to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-interference and anti-static cable protection pipe, comprising a protection pipe body, a shielding sleeve provided on the outside of the protection pipe body, slots opened on both sides inside the protection pipe body, a horizontal plate provided in the two sets of slots, conductive posts installed on the upper and lower sides of the ends of the horizontal plates, an installation groove provided on the outside of the rear end of the protection pipe body, two sets of installation holes opened in the installation groove, the two sets of conductive posts passing through the two sets of installation holes, a conductive ring installed in the installation groove, the ends of the two sets of conductive rings being connected to the conductive ring, and multiple sets of metal grounding terminals installed at equal intervals on the outside of the conductive ring.

[0006] As an improved technical solution, the front end of the protective tube body is provided with a rubber strip groove, and a conductive silicone rubber strip is installed in the rubber strip groove. The rear end of the protective tube body is provided with a convex ring.

[0007] As an improved technical solution, the slot and the cross plate are sealed and fixed with epoxy resin adhesive.

[0008] As an improved technical solution, the shielding sleeve is made of metal braided mesh.

[0009] As an improved technical solution, the conductive ring is made of a corrosion-resistant conductive material, and the metal grounding terminal is protruding.

[0010] As an improved technical solution, the convex ring is interference-fitted with the rubber strip groove of another protective tube.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are: I. This utility model features a horizontal plate installed inside the protective tube, with two sets of conductive posts mounted on the plate. These conductive posts are connected to a conductive ring outside the tube. The horizontal plate is connected to the conductive ring via through-holes in the conductive posts. The conductive ring is then electrically connected to an external ground or adjacent protective tube via a metal grounding terminal. When static electricity is generated in the cable, it is conducted through the horizontal plate and conductive posts to the conductive ring, and finally discharged through the metal grounding terminal. This creates a low-resistance static discharge path between the conductive posts and the conductive ring, achieving multi-layer anti-interference and anti-static protection. This prevents static electricity from accumulating inside the tube, reducing the risk of breakdown. The metal grounding terminals are evenly distributed outside the conductive ring, increasing the grounding area and ensuring grounding reliability.

[0012] II. This utility model has a conductive silicone rubber strip embedded in the rubber strip groove at the front end of the protective tube body and a convex ring at the rear end. When two protective tube bodies are connected, the convex ring is inserted into the rubber strip groove of the other tube, which squeezes and compresses the conductive silicone rubber strip, thereby enhancing the connection sealing and conductivity continuity between the protective tubes. In addition, the conductive silicone rubber strip prevents the intrusion of moisture and corrosive media and ensures that the static electricity discharge channel is not interrupted, making it suitable for humid or underground environments.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, an anti-interference and anti-static cable protection pipe includes a protection pipe body 1, a shielding sleeve 2 provided on the outside of the protection pipe body 1, slots 3 opened on both sides inside the protection pipe body 1, a horizontal plate 4 provided in the two sets of slots 3, conductive posts 5 installed on the upper and lower sides of the ends of the horizontal plate 4, an installation groove 6 provided on the outside of the rear end of the protection pipe body 1, two sets of installation holes 7 opened in the installation groove 6, the two sets of conductive posts 5 passing through the two sets of installation holes 7, a conductive ring 8 installed in the installation groove 6, the ends of the two sets of conductive rings 8 being connected to the conductive ring 8, and multiple sets of metal grounding terminals 9 installed at equal intervals on the outside of the conductive ring 8.

[0017] By installing a horizontal plate 4 inside the protective tube body 1, and two sets of conductive posts 5 on the horizontal plate 4, and connecting the two sets of conductive posts 5 to the conductive ring 8 outside the protective tube body 1, the protective tube body 1 provides mechanical support and cable accommodation space. The shielding sleeve 2 wraps around the outside of the tube body to form an electromagnetic shielding layer, effectively isolating external electromagnetic interference. The internal slot 3 is used to fix the horizontal plate 4. The horizontal plate 4 is connected to the conductive ring 8 through the installation hole 7 of the conductive posts 5. The conductive ring 8 is then electrically connected to the external ground or adjacent protective tube through the metal grounding terminal 9. When the cable generates static electricity, the static electricity is conducted to the conductive ring 8 through the horizontal plate 4 and the conductive posts 5, and finally discharged through the metal grounding terminal 9. The conductive posts 5 and the conductive ring 8 form a low-resistance static electricity discharge path, realizing multi-layer anti-interference and anti-static protection, avoiding the accumulation of static electricity inside the tube, reducing the risk of breakdown. The metal grounding terminals 9 are evenly distributed outside the conductive ring 8, increasing the grounding area and ensuring grounding reliability.

[0018] In other embodiments, a rubber strip groove 10 is provided at the front end of the protective tube body 1, a conductive silicone rubber strip 12 is installed in the rubber strip groove 10, and a protruding ring 11 is provided at the rear end of the protective tube body 1. By embedding a conductive silicone rubber strip 12 in the rubber groove 10 at the front end of the protective tube body 1 and providing a convex ring 11 at the rear end, when two sections of the protective tube body 1 are connected, the convex ring 11 is inserted into the rubber groove 10 of the other tube, causing the conductive silicone rubber strip 12 to be squeezed and compressed, which enhances the connection sealing and conductive continuity between the protective tubes. Furthermore, the conductive silicone rubber strip 12 not only prevents the intrusion of moisture and corrosive media, but also ensures that the static electricity discharge channel is not interrupted, making it suitable for humid or underground environments.

[0019] In other embodiments, the slot 3 and the cross plate 4 are sealed and fixed together by epoxy resin adhesive; Because epoxy resin adhesive has excellent water resistance and chemical stability, it can prevent corrosion inside the slot 3, extend its service life, and at the same time enhance the fixing strength of the cross plate 4, preventing the connection from loosening due to vibration.

[0020] In other embodiments, the shielding sleeve 2 is made of metal braided mesh; Because metal braided mesh provides high magnetic and electrical conductivity, it can effectively shield high-frequency electromagnetic interference. At the same time, it is flexible, not easy to break, and adaptable to bending installation environments, making it suitable as a raw material for shielding sleeve 2.

[0021] In other embodiments, the conductive ring 8 is made of a corrosion-resistant conductive material, and the metal grounding terminal 9 is protruding; Through this design, the corrosion-resistant material extends the service life of the conductive ring 8 in harsh environments, allowing the metal grounding terminal 9 to increase the contact area with the grounding point, improve the static electricity discharge efficiency, and avoid poor conductivity due to corrosion.

[0022] In other embodiments, the convex ring 11 is interference-fitted with the rubber strip groove 10 of another protective tube, and the conductive silicone rubber strip 12 is compressed to form a seal during connection; This design allows two sets of protective tube bodies 1 to be connected, and the rubber strip groove 10 and the convex ring 11 to be connected with an interference fit, ensuring that the two sets of protective tube bodies 1 are firmly connected and not easy to loosen. The conductive silicone rubber strip 12 fills the interface gap after being squeezed, effectively preventing electrochemical corrosion, preventing external electromagnetic signals from seeping in from the interface gap, and ensuring the long-term stability of the static electricity discharge channel.

[0023] This utility model provides an anti-interference and anti-static cable protection tube, the specific working principle of which is as follows: First, the cables are laid inside the protective conduit 1, with the horizontal plate 4 separating and arranging the cables to avoid mutual interference and facilitate heat dissipation. The outer shielding sleeve 2 is made of metal braided mesh, forming a Faraday cage effect to reflect or absorb external electromagnetic waves and prevent interference with cable signal transmission. Static charges generated during cable operation are conducted through the horizontal plate 4 to the conductive post 5, which is electrically connected to the conductive ring 8. The static charges are further conducted to the grounding system or adjacent protective conduit through the metal grounding terminal 9. The conductive ring 8 is made of corrosion-resistant material, and the metal grounding terminal 9 is raised to ensure good conductivity even in harsh environments such as humid or underground conditions.

[0024] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
