Description
Technical Field
[0001] This utility model relates to the field of cable tray technology, specifically to a surface-mounted integrated strong and weak current cable tray structure. Background Technology
[0002] In modern building electrical wiring systems, high-voltage and low-voltage lines are typically laid separately to avoid electromagnetic interference from high-voltage lines, which could affect the transmission quality of low-voltage signals (such as network, communication, and monitoring signals). Traditional wiring methods usually use separate cable trays or conduits for high-voltage and low-voltage lines. This not only increases construction complexity but also occupies more installation space. Especially in surface-mounted wiring scenarios, the neatness and aesthetics of the wiring are difficult to guarantee.
[0003] To address the aforementioned issues, existing technologies have proposed integrated high-voltage and low-voltage cable tray structures. These structures separate the high-voltage and low-voltage cable trays by installing partitions within the trays, thereby reducing electromagnetic interference. For example, CN 207098505 U discloses a high-voltage and low-voltage separated cable tray. However, existing integrated high-voltage and low-voltage cable trays still have the following shortcomings:
[0004] 1. The shielding layer is only installed on the inner wall of the isolation room, and the isolation between the strong and weak channels is not thorough, resulting in an unsatisfactory shielding effect and making it difficult to completely suppress the interference of strong power lines to weak power lines.
[0005] 2. Cables in power cable trays generate heat during long-term operation. Poor heat dissipation may lead to cable aging or even safety hazards. However, existing cable trays do not have heat dissipation structures.
[0006] 3. The cables in the high-voltage and low-voltage cable trays lack effective fixing devices, making them prone to loosening or displacement, which may cause poor contact or unstable signal transmission;
[0007] 4. The wire trough frames cannot be spliced together, making it difficult to quickly adjust the length according to on-site requirements. Summary of the Invention
[0008] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a cable tray structure that combines electromagnetic shielding, heat dissipation, cable fixing and modular expansion functions.
[0009] The technical solution adopted by this utility model to achieve the above-mentioned objectives is as follows: a surface-mounted integrated power and weak current cable tray structure, including a cable tray frame, a cable tray on the cable tray frame, a partition fixedly connected inside the cable tray, one side of the partition being a power cable tray and the other side being a weak current cable tray, a shielding layer fixedly connected to the inner wall of the weak current cable tray, a plug-in part at one end of the cable tray frame, a plug-in groove at the other end of the cable tray frame in conjunction with the plug-in part, and a closed cover plate slidably installed on the top of the cable tray frame, with the top surface of the partition plate abutting against the bottom surface of the closed cover plate.
[0010] In the above technical solution, in order to improve the heat dissipation effect of the high-voltage trough, multiple sets of heat dissipation holes are provided on the wire trough frame that are connected to the high-voltage trough.
[0011] In the above technical solution, in order to fix the cables inside the power supply tank, multiple sets of cable clips are fixedly connected to the inner wall of the power supply tank.
[0012] In the above technical solution, in order to fix the low-voltage wires in the low-voltage tray, multiple sets of hubs are fixedly connected to the inner wall of the low-voltage tray.
[0013] Furthermore, the hub includes an elastic band and Velcro, the elastic band is fixedly connected to the inner wall of the low-voltage channel, and the elastic band is connected to the inner wall of the low-voltage channel through the Velcro.
[0014] In the above technical solution, in order to realize the sliding connection between the closed cover plate and the wire groove frame, multiple sets of T-shaped sliding grooves are provided on the top of the wire groove frame, and a T-shaped sliding strip is fixedly connected to each set of T-shaped sliding grooves on the bottom surface of the closed cover plate, and the T-shaped sliding strip is slidably connected in the T-shaped sliding groove.
[0015] In the above technical solution, the plug-in part adopts a T-shaped plug strip, and the plug-in groove cooperates with the plug-in part to adopt a T-shaped slot.
[0016] In the above technical solution, the shielding layer is made of either aluminum foil or galvanized steel sheet;
[0017] Furthermore, to enhance the shielding effect, a grounding terminal is fixedly connected to the shielding layer.
[0018] In the above technical solution, in order to install the wire trough frame, a mounting bracket is fixedly connected to the bottom surface of the wire trough frame.
[0019] The beneficial effects of this utility model are:
[0020] 1. The partition completely and physically separates the high-voltage and low-voltage channels. Combined with the shielding layer and grounding terminal design inside the low-voltage channel, it effectively suppresses electromagnetic interference and ensures the stability of low-voltage signal transmission.
[0021] 2. Multiple sets of heat dissipation holes on the side wall of the power cable tray promote air circulation and reduce cable temperature rise. They are also equipped with cable clips on the inner wall to fix the power cables and prevent poor contact caused by shaking.
[0022] 3. The standardized interface design of the T-shaped insert and the connector slot enables rapid splicing of wire troughs, adapting to different length requirements;
[0023] 4. The cable management unit, consisting of elastic bands and Velcro, inside the low-voltage cable tray can be adjusted for tightness, thereby securing the low-voltage cables.
[0024] 5. The cable tray can be protected by the closed cover, and the sliding closed cover is easy to install and remove. Attached Figure Description

Detailed Implementation
[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Please see Figures 1 to 8 A surface-mounted integrated power and low-voltage cable tray structure includes a cable tray frame 100, which is a long strip-shaped shell. (See also...) Figure 1 A wire trough is provided on the wire trough frame 100, and a partition 200 is fixedly connected inside the wire trough. One side of the partition 200 is a high-voltage trough 101, and the other side is a low-voltage trough 102. The high-voltage trough 101 is used to lay high-voltage cables (such as power cords), and the low-voltage trough 102 is used to lay low-voltage lines (such as network cables and signal lines).
[0036] In addition, a shielding layer 1021 is fixedly connected to the inner wall of the low-voltage channel 102. In this embodiment, the shielding layer 1021 is made of either aluminum foil or galvanized steel sheet. Furthermore, to improve the shielding effect, please refer to [link to relevant documentation]. Figure 3 A grounding terminal 1022 is fixedly connected to the shielding layer 1021, so that the grounding terminal 1022 is connected to the grounding system through a wire to suppress electromagnetic interference;
[0037] Furthermore, please refer to Figure 1 The wire trough frame 100 is provided with multiple sets of heat dissipation holes 1011 that communicate with the high-voltage trough 101. These holes promote airflow and prevent heat buildup within the high-voltage trough 101. Further details can be found in the following section. Figure 2 In order to secure the cables inside the power cable tray 101, multiple sets of cable clips 300 (made of plastic or metal) are fixedly connected to the inner wall of the power cable tray 101 to secure the power cables and prevent them from loosening.
[0038] Furthermore, to secure the low-voltage wires within the low-voltage cable tray 102, multiple sets of cable collectors 400 are fixedly connected to the inner wall of the low-voltage cable tray 102. In this embodiment, please refer to... Figure 5 The cable management unit 400 includes an elastic band 401 and a Velcro strap 402. The elastic band 401 is fixedly connected to the inner wall of the low-voltage cable tray 102. The elastic band 401 is connected to the inner wall of the low-voltage cable tray 102 through the Velcro strap 402. This allows the low-voltage cables to be bundled together in a concentrated manner, preventing the low-voltage cables from becoming messy.
[0039] Furthermore, please refer to Figure 1A sealing cover 500 is slidably installed on the top of the wire trough frame 100. The top surface of the partition 200 abuts against the bottom surface of the sealing cover 500. In this way, the sealing cover 500 can protect the internal wiring and completely isolate the low-voltage wire trough 102 from the high-voltage wire trough 101. For details, please refer to [link to relevant documentation]. Figure 2 , Figure 4 The top of the online slot frame 100 is provided with multiple sets of T-shaped sliding grooves 103, and a T-shaped sliding strip 501 is fixedly connected to each set of T-shaped sliding grooves 103 on the bottom surface of the closed cover plate 500. The T-shaped sliding strip 501 is slidably connected in the T-shaped sliding groove 103, and there is an interference fit between the T-shaped sliding strip 501 and the T-shaped sliding groove 103. That is, when the closed cover plate 500 is slidably installed, it is fixed by friction.
[0040] For optimization, please refer to Figures 6 to 8 One end of the wire groove frame 100 is provided with a plug-in part 104. In this embodiment, a T-shaped plug is used. The other end of the wire groove frame 100 is provided with a plug-in groove 105 in conjunction with the plug-in part 104. The plug-in groove 105 and the plug-in part 104 are provided with a T-shaped slot. In this way, multiple sets of wire groove frames 100 can be spliced together according to the actual length requirements, and the splicing part has good sealing performance.
[0041] Finally, please see Figure 1 To enable the installation of the wire trough frame 100, a mounting bracket 600 (such as an L-shaped angle steel) is fixedly connected to the bottom surface of the wire trough frame 100, and the wire trough frame 100 can be fixed to the wall by expansion bolts.
