Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-interference component technology, and in particular to an anti-interference component for remote data transmission in PLC. Background Technology
[0002] Based on years of experience and expertise in industrial control, the PLC wireless communication module pioneered a triple communication approach combining GPRS, SMS, and telephone, completely resolving the instability issues of traditional GPRS modules. Even if the GPRS network is interrupted, remote SMS control, SMS query, SMS alarm, and telephone alarm can still be achieved via SMS or telephone. The PLC wireless communication module provides a comprehensive solution including free host computer configuration software, GPRS control module, and cloud monitoring.
[0003] In the process of implementing remote data transmission for PLCs, signal isolators are usually preferred to ensure signal stability and improve the system's anti-interference capability. However, signal isolators require grounding to function properly, so the grounding wire is usually exposed on the ground. This increases the risk of pedestrians or other objects accidentally kicking or touching the grounding wire. Once the grounding wire is kicked or subjected to external interference, it may affect the stability of the signal isolator, potentially leading to a decrease in its performance and thus reducing the overall system's anti-interference effect. Therefore, this invention proposes a grounding protection and anti-interference component for remote PLC data transmission. Utility Model Content
[0004] The purpose of this invention is to address the problem in the background technology that in PLC remote data transmission systems, the signal isolator relies on a grounding wire for operation, but the exposed grounding wire is easily kicked or bumped by pedestrians or objects and is subject to external interference, which leads to a decrease in the stability of the signal isolator and a reduction in the anti-interference effect of the entire system. The invention proposes an anti-interference component for PLC remote data transmission.
[0005] The technical solution of this utility model is as follows: an anti-interference component for remote data transmission of PLC, including a housing, a platform fixedly connected to the rear end of the inner wall of the housing, multiple sets of PLC boxes fixedly connected to the front end of the platform, cables fixedly connected to the top of each PLC box, multiple sets of conduits passing through the top of the housing, and the outer wall of each cable sleeved with the inner wall of the conduit.
[0006] The bottom of the box has multiple sets of placement frames. The bottom of the inner wall of each set of placement frames is fixedly connected to a hollow frame. The top of the inner wall of each set of placement frames is fitted with a signal isolator. The top two terminals of the signal isolator are equipped with wires. The top of the wires is movably connected to the front terminal of the PLC box.
[0007] A square tube is fixedly connected to the inner wall of the hollow frame, and a rubber tube is fixedly connected to the inner wall of the square tube. A grounding wire is fixedly connected to the bottom of the signal isolator. The inner wall of the rubber tube is sleeved with the top of the outer wall of the grounding wire, and an arc-shaped rubber sleeve is installed at the bottom of the outer wall of the grounding wire.
[0008] A first U-shaped shell is installed on one side of the outer wall of the square tube, and a second U-shaped shell is installed on the other side of the outer wall of the square tube. Multiple sets of fluorescent strips are fixedly connected to the opposite sides of the first U-shaped shell and the second U-shaped shell, and rubber strips are fixedly connected to both ends of the opposite sides of the first U-shaped shell and the second U-shaped shell.
[0009] Optionally, the bottom ends of the concave surfaces of the first U-shaped shell and the second U-shaped shell are fixedly connected to the outer wall of the arc-shaped rubber sleeve, and the inner wall of the arc-shaped rubber sleeve is in contact with the bottom end of the outer wall of the grounding wire.
[0010] Optionally, the top edges of the adjacent sides of the first U-shaped shell and the second U-shaped shell are both perforated with insert rings, and the bottom ends of the outer walls on both sides of the square tube are fixedly connected with insert blocks, the outer walls of the insert blocks being inserted into the inner walls of the insert rings.
[0011] Optionally, a first mounting plate is fixedly connected to both outer walls of the first U-shaped shell, and a second mounting plate is fixedly connected to both outer walls of the second U-shaped shell.
[0012] Optionally, threaded rods are fixedly connected to both ends of the first mounting plate, the threaded rods penetrate the second mounting plate, and nuts are threaded to the outer ring of the end of the threaded rods penetrating the second mounting plate.
[0013] Optionally, a U-shaped sliding frame is fixedly connected to the front side wall of the box, and a box door is fitted onto the inner wall of the U-shaped sliding frame.
[0014] Optionally, two sets of L-shaped mounting plates are fixedly connected to the rear side wall of the enclosure, and multiple power supplies are provided through the rear side wall of the enclosure. The connection terminals of the power supplies are movably connected to the wiring terminals of the signal isolator.
[0015] In summary, this application includes at least one of the following beneficial technical effects:
[0016] This utility model forms a multi-layer protective structure through the rubber tube on the inner wall of the square tube, the arc-shaped rubber sleeve at the bottom of the grounding wire, and the first U-shaped shell and the second U-shaped shell wrapped around it. This prevents the grounding wire from being exposed and accidentally kicked or interfered with by external forces, thereby preventing the stability of the signal isolator from decreasing and ensuring the anti-interference effect of the system.
[0017] Furthermore, the fluorescent strips on the opposite sides of the first and second U-shaped shells can alert pedestrians in dim environments, reducing the risk of collisions. The rubber strips on the opposite sides of the two shells can be glued together to improve the sealing performance, reduce the intrusion of dust and moisture, enhance the anti-interference effect, and extend the overall service life of the anti-interference components.
[0018] Furthermore, the U-shaped shell can be quickly positioned by inserting the plug and the ring. Combined with the fixing structure of the threaded rod, the first mounting plate, the second mounting plate and the nut, assembly and disassembly can be easily completed. The components are integrated into the box and no additional programs need to be written for the PLC. Customers can use it with simple configuration and adapt to the needs of PLC remote data transmission scenarios.
[0019] In summary, this utility model provides multi-layered protection through rubber tubes, arc-shaped rubber sleeves, and U-shaped shells, preventing the exposed grounding wire from being interfered with by external forces, ensuring the stable operation of the signal isolator. The fluorescent strip enhances safety in dimly lit environments, the rubber strip strengthens the seal and extends the service life, and the plug-in ring and threaded rod structure facilitates installation. It is suitable for PLC remote data transmission scenarios, requires no additional programming, and is easy to use. Attached Figure Description

Cables 4 are fixedly connected to the top of each PLC box 3. Multiple conduits 5 pass through the top of the housing 1. The outer wall of each cable 4 is sleeved with the inner wall of the conduit 5.
[0033] Combination Figure 3As shown, multiple sets of placement frames 6 are opened through the bottom of the housing 1. The bottom surface of the placement frames 6 and the bottom surface of the housing 1 are both set on the same horizontal plane. Hollow frames 7 are fixedly connected to the bottom of the inner wall of each set of placement frames 6. The hollow frames 7 can support the signal isolators 8. The hollow frames 7 have square through holes running vertically through them. The signal isolators 8 are fitted onto the top of the inner wall of each set of placement frames 6. Wires 9 are installed at the wiring ports at both ends of the top of the signal isolators 8. The top of the wires 9 are movably connected to the wiring port at the front end of the PLC box 3. By setting the wires 9, the PLC box 3 and the signal isolators 8 can be connected together. Two sets of L-shaped mounting plates 26 are fixedly connected to the back side wall of the housing 1.

The inner wall of the rubber tube 11 is sleeved with the top of the outer wall of the grounding wire 12, and an arc-shaped rubber sleeve 16 is installed at the bottom of the outer wall of the grounding wire 12. By setting the rubber tube 11 and the arc-shaped rubber sleeve 16, the grounding wire 12 can be wrapped and protected. A first U-shaped shell 13 is installed on one side of the outer wall of the square tube 10, and a second U-shaped shell 14 is installed on the other side of the outer wall of the square tube 10.
