Description

Technical Field

[0001] This utility model relates to the field of circuit pipeline installation technology, and in particular to a strong and weak current anti-interference structure. Background Technology

[0002] High-voltage and low-voltage interference prevention refers to the technical measures taken in electrical systems to prevent electromagnetic interference from high-voltage (high-voltage, high-current power systems) to low-voltage (low-voltage, low-current signal or control systems). Its core objective is to ensure that low-voltage equipment (such as networks, communications, and sensors) can still operate stably in high-voltage environments, preventing signal distortion, data loss, or equipment damage.

[0003] During the wiring process inside a house, since the placement of various electrical appliances is scattered throughout the room, high-voltage and low-voltage lines are usually laid together on the ceiling. However, during the connection of high-voltage and low-voltage lines, it is inevitable that they will cross. At the crossing point, the current in the high-voltage line generates a magnetic field, which will affect the stability of signal transmission in the low-voltage line, resulting in unstable video, audio, and network signals. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that when strong and weak power lines cross, the magnetic field generated by the current in the strong power line at the crossing point will affect the stability of signal transmission in the weak power line, and to propose a strong and weak power anti-interference structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A strong and weak current anti-interference structure includes a fixed shaft and two fixed seats rotatably disposed at both ends of the fixed shaft. A wire plate is detachably disposed on each of the two sets of fixed seats. At least one pair of retaining plates is fixedly disposed on the bottom of the wire plate. Each of the two ends of the fixed seat has a retaining groove corresponding to a pair of retaining plates. The end of the retaining plate away from the wire plate is engaged with the corresponding retaining groove. A shielding tube is provided, through which a wire passes. The top of the wire plate has multiple arc-shaped retaining grooves, and the shielding tube is engaged with the retaining grooves.

[0007] In order to limit the position of the wire plate, preferably, a limiting block is fixedly provided on the end face of the fixed seat away from the fixed shaft, and a limiting groove matching the limiting block is opened at the bottom of the wire plate, and the limiting groove is slidably connected to the limiting block.

[0008] To reduce the slippage of the shielding tube along the axial direction of the tube clamping groove, preferably, a positioning post is fixedly installed inside the tube clamping groove, and a positioning hole corresponding to the positioning post is opened on the outer wall of the shielding tube, and the positioning hole is slidably connected to the positioning post.

[0009] To facilitate the installation of the shielding tube, the axis of the positioning column is further perpendicular to the bottom end face of the wire plate.

[0010] Preferably, the shielding tube includes an outer layer and an insulating layer, the insulating layer is fixedly disposed on the inner wall of the outer layer, and a shielding layer is fixedly disposed between the outer layer and the insulating layer.

[0011] Furthermore, the shielding layer is a metal woven mesh.

[0012] Furthermore, the outer layer is made of polyvinyl chloride.

[0013] Furthermore, at least one rubber sleeve is fixedly disposed inside the insulation layer, and the inner wall of the rubber sleeve abuts against the outer wall of the conductor.

[0014] Preferably, the plurality of the tube slots are equidistantly distributed along the long side of the line plate.

[0015] Preferably, the length of the shielding tube is greater than the length of the wire plate.

[0016] Compared with the prior art, this utility model provides a strong and weak electrical anti-interference structure, which has the following beneficial effects:

[0017] 1. This strong and weak current anti-interference structure has fixed seats at both ends of the fixed shaft, and wire plates are detached and installed on the fixed seats. The wires are clamped to the wire plates through the shielding tube. On the one hand, it can separate the crossing strong and weak current lines and reduce electromagnetic interference between them. On the other hand, the wire plates and shielding tubes can be detached and connected, which makes it convenient to replace them according to the number of wires, the distance and the diameter of the wires, thus improving the performance.

[0018] 2. This strong and weak current anti-interference structure has a positioning post fixed in the tube slot and a positioning hole on the shielding tube. When the shielding tube is locked in the tube slot, it can reduce the phenomenon of the shielding tube sliding along the axis of the tube slot, reduce the possibility of the shielding tube slipping off the wire plate, and improve the use effect.

[0019] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model has fixed seats rotatably installed at both ends of a fixed shaft, and wire plates are detachably installed on the fixed seats. The wires are clamped to the wire plates through shielding tubes. On the one hand, it can separate the crossing high-voltage and low-voltage lines and reduce electromagnetic interference between them. On the other hand, the wire plates and shielding tubes can be detached and connected, which makes it convenient to replace them according to the number of wires, the distance between them and the diameter of the wires, thereby improving the performance.

[0025] 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.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Example:

[0028] Reference Figures 1-4A strong and weak current anti-interference structure includes a fixed shaft 1 and a fixed seat 2 rotatably mounted at both ends of the fixed shaft 1. The distance between the two sets of fixed seats 2 is greater than or equal to 10 cm, preferably 10 cm. By rotatably mounting the two sets of fixed seats 2 at both ends of the fixed shaft 1, the cross angle of the actual lines can be adjusted, improving the flexibility of use. A line plate 3 is detachably mounted on each of the two sets of fixed seats 2. At least one pair of locking plates 303, preferably a pair, are fixedly mounted on the bottom of the line plate 3. A slot 202 corresponding to the pair of locking plates 303 is opened at the bottom of both ends of the fixed seat 2. The end of the locking plate 303 away from the line plate 3 is engaged with the corresponding slot 202. Furthermore, to facilitate the engagement of the locking plate 303 with the corresponding slot, a slot 202 is provided. The slot 202 is disengaged. A push plate is fixedly installed at the end of the clamping plate 303 away from the wire plate 3. The push plate can push the clamping plate 303 to disengage from the slot 202, thereby removing the wire plate 3 from the fixing seat 2. The shielding tube 4 is through which the wire passes. Multiple arc-shaped clamping slots 301 are opened on the top of the wire plate 3. There are two to ten clamping slots 301. Here, we prefer seven. The multiple clamping slots 301 are evenly distributed along the long side of the wire plate 3. The shielding tube 4 is clamped and connected in the clamping slots 301 to fix the shielding tube 4. The length of the shielding tube 4 is greater than the length of the wire plate 3. That is to say, when the two sets of fixing seats 2 are distributed in a cross manner, the length of the shielding tube 4 should completely span the width when the wires are side by side to improve the effective shielding effect of the shielding tube 4.

[0029] In use, a fixed base 2 is rotatably installed at both ends of the fixed shaft 1, and a wire plate 3 is detached and installed on the fixed base 2. The wires are clamped onto the wire plate 3 through the shielding tube 4. On the one hand, the crossing high-voltage lines and low-voltage lines can be separated from each other to reduce electromagnetic interference. On the other hand, the wire plate 3 and the shielding tube 4 can be detached and connected, which makes it convenient to replace them according to the number of wires, the distance and the diameter of the wires, thus improving the performance.

[0030] Reference Figure 3 and Figure 4 A limiting block 201 is fixedly installed on the end face of the fixed seat 2 away from the fixed shaft 1. A limiting groove 304 matching the limiting block 201 is opened at the bottom of the line plate 3. The limiting groove 304 and the limiting block 201 are slidably connected. In use, by fixing the limiting block 201 on the fixed seat 2 and opening the limiting groove 304 at the bottom of the line plate 3, when the card plate 303 and the card groove 202 are engaged, the movement of the line plate 3 on the fixed seat 2 can be reduced, and the stability between the line plate 3 and the fixed seat 2 can be improved.

[0031] Reference Figure 3 and Figure 4A positioning post 302 is fixedly installed inside the tube slot 301. A positioning hole corresponding to the positioning post 302 is opened on the outer wall of the shielding tube 4. The positioning hole and the positioning post 302 are slidably connected, which can reduce the sliding of the shielding tube 4 along the axial direction of the tube slot 301. The axis of the positioning post 302 is perpendicular to the bottom end face of the wire plate 3. When the shielding tube 4 is installed into the tube slot 301, it is convenient to connect the positioning hole and the positioning post 302. In use, by fixing the positioning post 302 inside the tube slot 301 and opening the positioning hole on the shielding tube 4, when the shielding tube 4 is engaged in the tube slot 301, the phenomenon of the shielding tube 4 sliding along the axial direction of the tube slot 301 can be reduced, thereby improving the shielding effect.

[0032] Reference Figure 4 Here, we design the shielding tube 4 as an outer layer 401 and an insulating layer 403. The insulating layer 403 is fixedly disposed on the inner wall of the outer layer 401, and a shielding layer 402 is fixedly disposed between the outer layer 401 and the insulating layer 403. The shielding layer 402 is a metal braided mesh, such as copper mesh, aluminum foil, or stainless steel strip, preferably aluminum foil. The material of the outer layer 401 is polyvinyl chloride. In addition, the insulating layer 403 is silicone rubber or epoxy resin, preferably silicone rubber, to improve the shielding effect.

[0033] Reference Figure 1 and Figure 4 At least one rubber sleeve 404 is fixedly disposed inside the insulation layer 403. Here, we prefer two, which are symmetrically distributed. The inner wall of the rubber sleeve 404 abuts against the outer wall of the wire. In use, by fixing the rubber sleeve 404 inside the insulation layer 403, the wire can be clamped to a certain extent, reducing the movement of the wire in the shielding tube 4 and improving the use effect.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
