Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically to a modular, isolated cable tray. Background Technology

[0002] Traditional isolated cable tray wiring refers to a wiring method in which wires or cables are placed inside cable trays to achieve electrical isolation and physical protection. Cable trays are typically made of metal (such as steel or aluminum) or plastic and are designed in a closed or semi-closed form to ensure the safety and reliability of the internal wiring. This wiring method is widely used in industrial, commercial, and residential buildings for various purposes such as power transmission and communication signal transmission.

[0003] When multiple wire harnesses need to coexist in a cable tray, the space inside the tray becomes very crowded. Insufficient spacing between the harnesses can lead to physical contact or friction, increasing the risk of damage. Too many harnesses crammed together make management and maintenance more difficult, especially when troubleshooting or replacing wires. Utility Model Content

[0004] This utility model proposes a modular, isolated cable tray, which solves the problems of crowded cable harness arrangement space, easy damage, and inconvenient maintenance in related technologies.

[0005] The technical solution of this utility model is as follows: A modular, isolated cable tray, comprising:

[0006] The main body of the cable tray is U-shaped and consists of a bottom plate and two side plates. The bottom plate and the two side plates form a wiring space. The bottom plate has an opening that connects the outside of the main body of the cable tray with the wiring space.

[0007] A first plate is disposed on the base plate at the opening, and the first plate has a plurality of through holes.

[0008] A wire carrier is movably disposed within the through hole and has an arc-shaped support portion that extends into the wiring space to support the wire bundle. After the wire carrier is moved, the length of its extension into the wiring space increases or decreases.

[0009] Optionally, a plurality of the through holes are arranged at intervals along the width direction of the first plate.

[0010] Optionally, the through hole has an internal thread;

[0011] The wire carrier also has a rod portion with external threads, and the rod portion is threadedly connected to the through hole.

[0012] Optionally, the width of the cable carrier is smaller than the width of the opening, and the portion of the opening located on one side of the cable carrier is an inspection port.

[0013] Optionally, it also includes:

[0014] The second plate is movably mounted on the base plate and located at the opening. After the second plate is moved, it can either block or unblock the inspection opening.

[0015] Optionally, the second plate has a slot, the wire carrier is located in the slot, and there is a gap between the wire carrier and the bottom of the slot to form an airflow space. The airflow space is connected to the wiring space through the through hole.

[0016] Optionally, the second plate also has a shielding portion that shields one end of the airflow space.

[0017] Optionally, it also includes:

[0018] A baffle is movably mounted on the second plate, which, after being moved, blocks or unblocks the other end of the airflow space.

[0019] Optionally, both the baffle and the second plate have threaded holes.

[0020] Optionally, the first plate is detachably mounted on the base plate.

[0021] The working principle and beneficial effects of this utility model are as follows:

[0022] In this invention, the cable carrier is movable within a through-hole and features an arc-shaped support that extends into the wiring space. By moving, the length of the cable carrier extending into the wiring space can be increased or decreased. This mobility allows the cable carrier to flexibly adjust its support position within the wiring space according to the thickness and quantity of the cable bundle and specific wiring requirements. The arc-shaped support better conforms to the shape of the cable bundle, providing stable support and preventing deformation or compression due to gravity or external forces, effectively protecting the cable bundle and ensuring normal circuit operation. This modular, isolated cable tray, through the synergistic effect of its various structural components, demonstrates advantages in wiring flexibility, adaptability to cable bundles, and cable bundle protection, meeting diverse wiring needs.

[0034] Reference Figures 1-5 A modular, isolated cable tray is proposed. The main body 1 of the cable tray is U-shaped and consists of a base plate 101 and two side plates 102. The base plate 101 and the two side plates 102 form a cable routing space 103. The base plate 101 has an opening 104 that connects the outside of the main body 1 of the cable tray to the cable routing space 103. A first plate 2 is disposed on the base plate 101 at the opening 104 and has several through holes 201. A cable carrier 3 is movably disposed within the through holes 201 and has an arc-shaped support 301 that extends into the cable routing space 103 to support the cable bundle. After the cable carrier 3 moves, its length extending into the cable routing space 103 increases or decreases.

[0035] In this embodiment, the main body 1 of the cable tray is U-shaped, consisting of a base plate 101 and two side plates 102, which together form a wiring space 103. The base plate 101 has an opening 104 that connects the outer side of the main body 1 of the cable tray to the wiring space 103. The U-shaped design allows the cable tray to have sufficient space while remaining relatively open, facilitating the arrangement and organization of wire harnesses. The opening 104 provides a channel for the installation of the cable carrier 3 and for the wire harnesses to enter and exit the wiring space 103, giving the cable tray flexibility in wiring.

[0036] The first plate 2 serves to connect and position the wire carrier 3. The presence of the through hole 201 provides a location for the installation of the wire carrier 3, and different positions of the through hole 201 can be selected to install the wire carrier 3 according to the actual number of wire harnesses and layout requirements, thereby enhancing the adaptability of the wire trough to the layout of the wire harness.

[0037] The cable carrier 3 is movable within the through hole 201 and has an arc-shaped support 301 that extends into the wiring space 103. By moving, the length of the cable carrier 3 extending into the wiring space 103 can be increased or decreased. The mobility of the cable carrier 3 allows it to flexibly adjust its support position within the wiring space 103 according to the thickness and quantity of the wire harness and specific wiring requirements. The arc-shaped support 301 better conforms to the shape of the wire harness, providing stable support and preventing deformation or compression due to gravity or external forces, effectively protecting the wire harness and ensuring normal operation of the circuit. This modular, isolated cable tray, through the synergistic effect of its various structural components, demonstrates advantages in wiring flexibility, adaptability to wire harnesses, and protection of wire harnesses, meeting diverse wiring needs.

[0038] Furthermore, a number of through holes 201 are arranged at intervals along the width direction of the first plate 2.

[0039] In this embodiment, several through holes 201 are arranged at intervals along the width direction, allowing the wire carrier 3 to be installed in the through holes 201 at different positions. During wire harness routing, the position of the wire carrier 3 can be flexibly adjusted according to the number of wire harnesses, their routing, and space requirements, achieving a reasonable layout of the wire harnesses. For example, when multiple sets of wire harnesses with different specifications or functions need to be arranged, the wire harnesses can be arranged separately by selecting wire carriers 3 at different positions, avoiding mutual interference.

[0040] The spaced arrangement makes full use of the space in the width direction of the first plate 2, accommodating more wire carriers 3 within the limited cross-section of the wire trough, thereby supporting more wire bundles. This is especially important for wiring scenarios with limited space but a large number of wire bundles, such as wiring inside small electrical equipment, effectively improving the space utilization rate of the wire trough.

[0041] The neat and spaced arrangement makes it easy for installers to quickly locate the installation position of the cable carrier 3, improving installation efficiency. During later maintenance, it also facilitates the location and repair of a specific cable carrier 3 and the wiring harness it carries, reducing maintenance difficulty.

[0042] Furthermore, the through hole 201 has an internal thread; the wire carrier 3 also has a rod 302 with an external thread, and the rod 302 is threadedly connected to the through hole 201.

[0043] In this embodiment, the through hole 201 has an internal thread, and the rod portion 302 of the wire carrier 3 has an external thread, which matches the internal thread of the through hole 201 to achieve a threaded connection between the two. The engagement of the external thread and the internal thread of the through hole 201 provides a reliable connection method, ensuring that the wire carrier 3 can be firmly installed on the first plate 2 under different working conditions (such as vibration during equipment operation, accidental contact by personnel, etc.), thereby improving the reliability of the overall structure of the wire trough. By rotating the rod portion 302 of the wire carrier 3, the length of the wire carrier 3 extending into the wiring space 103 can be easily changed. Moreover, this adjustment method can be performed at any time, is simple to operate, and has high precision, and can adjust the support state in a timely manner according to changes in the thickness and quantity of the wire harness.

[0044] Furthermore, the width of the cable carrier 3 is smaller than the width of the opening 104, and the portion of the opening 104 located on one side of the cable carrier 3 is an inspection port 4.

[0045] In this embodiment, the width difference of the wire groove provides additional functional space, that is, a part of the opening 104 is reserved as the maintenance port 4, which avoids the wire carrier 3 from completely occupying the opening 104, ensures the existence of the maintenance port 4, and provides the necessary passage for subsequent inspection and maintenance work.

[0046] A portion of the opening 104 located on one side of the cable carrier 3 serves as an inspection port 4, providing personnel with a direct channel to observe and operate the interior of the cable tray. When the cable tray malfunctions or maintenance is required on the wiring space 103 and the cable carrier 3, personnel can directly observe the internal condition through the inspection port 4, checking for damage to the wiring harness, whether the cable carrier 3 is functioning properly, etc., without disassembling the entire cable tray, saving maintenance time and effort. The inspection port 4 makes internal operations more convenient; for example, it allows for easy cleaning of dust and debris inside the cable tray, adjustment of the position of the cable carrier 3, or replacement of damaged cable carrier 3, reducing the complexity and workload of maintenance and improving the maintenance efficiency of the cable tray. Timely detection and resolution of problems in the cable tray through the inspection port 4 helps ensure the normal operation of the wiring system within the cable tray, thereby ensuring the stable operation of connected electrical equipment or wiring systems and reducing the risk of equipment failure due to cable tray problems.

[0047] This design with inspection port 4 facilitates the maintenance and repair of the modular isolated cable tray, improving the maintainability of the cable tray and the overall reliability of the equipment.

[0048] Furthermore, the second plate 5 is movably mounted on the base plate 101, located at the opening 104. After the second plate 5 is moved, it can either block or unblock the inspection opening 4.

[0049] In this embodiment, the second plate 5 is movably mounted on the base plate 101 and positioned at the opening 104. When the cable tray is operating normally and does not require maintenance, the second plate 5 is moved to block the inspection opening 4, preventing dust, debris, and other foreign objects from entering the wiring space 103 and protecting the wire harness and carrier 3. It also prevents accidental contact with internal live wiring, improving safety. When maintenance is required, the second plate 5 is moved to remove the obstruction of the inspection opening 4, allowing maintenance personnel to easily inspect and maintain the wiring space 103 and carrier 3 through the inspection opening 4, continuing the advantage of easy maintenance. This design, which allows for flexible control of the inspection opening 4's state, enables the cable tray to maintain good sealing under normal conditions while quickly providing a maintenance passage when necessary, improving its adaptability to different operating stages and meeting the needs of various working conditions.

[0050] Furthermore, the second plate 5 has a slot 501, the wire carrier 3 is located in the slot 501, and there is a gap between the wire carrier 3 and the bottom of the slot 501, which is an airflow space 6. The airflow space 6 is connected to the wiring space 103 through the through hole 201.

[0051] In this embodiment, the airflow space 6 creates conditions for air circulation inside the wire trough. Air can flow within this specific space, which helps dissipate heat from the wire harness. Since the wire harness generates heat during operation, good heat dissipation can effectively reduce the operating temperature of the wire harness, extend its service life, and improve the stability and safety of the circuit operation.

[0052] On the other hand, airflow helps to remove any moisture that may be present in the wiring space 103, keeping the inside of the cable tray dry and reducing the risk of corrosion to the wire harness and carrier 3 caused by the humid environment, thereby further improving the reliability and durability of the electrical components in the cable tray.

[0053] Furthermore, the second plate 5 also has a shielding part 502, which shields one end of the airflow space 6.

[0054] The shielding part 502 acts as a barrier, preventing external dust, debris, and other foreign objects from entering the airflow space 6. In actual use environments, cable trays may encounter dust and debris; the shielding part 502 reduces the risk of foreign objects entering the wiring space 103 through the airflow space 6. This effectively protects the wire harnesses and cable carriers 3 inside the cable tray, preventing the accumulation of foreign objects from affecting heat dissipation, causing electrical faults, or accelerating component wear, thus extending the service life of the cable tray and its internal components. In some humid environments, moisture in the air may move with the airflow. The shielding part 502 blocks one end of the airflow space 6, reducing the possibility of moisture directly entering the airflow space 6 and then penetrating into the wiring space 103. This helps maintain a dry environment inside the cable tray, reducing problems such as wire harness short circuits and cable carrier corrosion caused by moisture, thus improving the reliability of the cable tray in humid environments.

[0055] Furthermore, the baffle 7 is movable on the second plate 5, and after moving, it blocks or unblocks the other end of the airflow space 6.

[0056] In this embodiment, the structure of the newly added baffle 7 and its advantages are analyzed in detail below:

[0057] The movement of the baffle 7 can block or unblock the other end of the airflow space 6. It corresponds to the existing blocking part 502 on the second plate 5, and together they control the two ends of the airflow space 6, determining the opening and closing state of the two ends of the airflow space 6.

[0058] By moving the baffle 7 to block or open the other end of the airflow space 6, the flow rate and volume of air within the airflow space 6 can be flexibly adjusted. For example, when heat dissipation requirements are high, opening the baffle 7 allows airflow to pass through the airflow space 6 more smoothly, enhancing convection and carrying away more heat. Conversely, in harsh external environments, such as when there is heavy dust, closing the baffle 7 reduces airflow entry, lowering the risk of foreign objects entering the cable tray while maintaining a certain level of heat dissipation capacity.

[0059] Different electrical devices generate varying amounts of heat during operation. By flexibly controlling the baffle 7, the cable tray can adapt to various operating conditions. For wiring of equipment that generates a lot of heat, airflow can be maximized to enhance heat dissipation; for equipment that generates less heat and is more sensitive to the environment, airflow can be appropriately reduced to prevent excessive dust and moisture from entering.

[0060] When the baffle 7 blocks the other end of the airflow space 6, it works in conjunction with the blocking part 502 at the other end to form a more robust protective structure. In dusty, humid, or liquid-splashed environments, it can more effectively prevent dust, moisture, or liquid from entering the wiring space 103 through the airflow space 6, further protecting the wire harness and the cable carrier 3 and reducing electrical faults and component damage caused by these factors.

[0061] Furthermore, both the baffle 7 and the second plate 5 have threaded holes 8.

[0062] In this embodiment, by providing threaded holes 8 on the baffle 7 and the second plate 5, bolts or other connecting parts can be used to fasten the connection through the threaded holes 8, forming a high-strength mechanical connection. In practical applications, the cable tray may be affected by external forces such as vibration and impact. The robust connection ensures that the baffle 7 can reliably block or open the other end of the airflow space 6 under any circumstances, maintaining a stable airflow environment inside the cable tray while ensuring that the protective performance is not affected, thus guaranteeing the normal operation of the wiring system inside the cable tray.

[0063] Furthermore, the first plate 2 is detachably mounted on the base plate 101.

[0064] In this embodiment, the detachable first plate 2 facilitates operation when installing the cable tray. For example, if bolt connection is used, the installer can first install the cable carrier 3 on the first plate 2, and then install the assembled first plate 2 into the opening 104 of the base plate 101. Compared with directly installing the cable carrier 3 into the opening 104 of the base plate 101, this step-by-step installation method is easier to operate and improves installation efficiency.

[0065] When the cable carrier 3 or the first plate 2 within the cable tray is damaged and needs replacement, the entire cable tray does not need to be disassembled. Simply remove the first plate 2 from the base plate 101 for repair or replacement. This significantly shortens maintenance time, reduces maintenance costs, and minimizes the impact on the entire cabling system. Transporting and storing the first plate 2 separately from the base plate 101 reduces the possibility of damage due to collisions during transport. Especially for more fragile components, such as the cable carrier 3 mounted on the first plate 2, separate storage provides better protection and improves the safety of product transportation and storage. This structural feature of the first plate 2 being detachably mounted on the base plate 101 brings significant advantages to the modular, isolated cable tray in terms of installation, maintenance, usage flexibility, and transportation and storage, making it more practical and economical.

[0066] 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.
