[0035] Cable trays typically support multiple cables. In traditional cable trays, these cables are housed in the same space without any separation between them. Among these cables are both positive and negative cables. If the protective layer of any cable is damaged, not only will leakage occur, but the damaged points in the positive and negative cables may also come into contact, leading to a more serious short circuit. The cable tray of this application can separate multiple cables, preventing short circuits even if the protective layers of the positive and negative cables are damaged. This ensures stable system operation and reduces the risk of fire and other accidents.

[0036] like Figure 1 As shown in the figure, this application embodiment provides a cable tray, which includes a cable tray body 101 and an isolation component 201. The cable tray body 101 is the main structure that carries a plurality of cables, and the isolation component 201 is installed on the cable tray body 101 to separate the plurality of cables from each other and prevent the cables from contacting each other.

[0037] In some examples, such as Figure 2 As shown, the cable tray body 101 is hollow, and several cables are placed inside the cable tray body 101, so the cable tray body 101 can protect each cable.

[0038] Specifically, the cable tray body 101 is formed into a box-shaped structure with a top opening, and each cable is placed inside the cable tray body 101 along the top opening. In addition, since the cables need to be transmitted over long distances, the cable tray body 101 also has a relatively large length.

[0039] Furthermore, such as Figure 3 As shown, the isolation component 201 is located inside the cable tray body 101, and the isolation component 201 is detachably connected to the cable tray body 101, which facilitates the separate processing and manufacturing of the cable tray body 101 and the isolation component 201, reducing process difficulty and manufacturing costs.

[0040] Meanwhile, the isolation component 201 is formed as a plate-like structure, and the isolation component 201 is provided with a plurality of support structures 202, each support structure 202 penetrating through the isolation component 201. Specifically, the support structure 202 is formed as a support hole.

[0041] Each cable passes through the isolation component 201 along the support structure 202, and under the support of the support structure 202, each cable has a relatively stable position. It is understood that several support structures 202 are provided, with a certain interval between each support structure 202, so that there is a gap between the cables passing through different support structures 202, preventing the cables from contacting each other. Even if the protective layer of the positive and negative cables is accidentally damaged, it can prevent the damaged parts of the positive and negative cables from touching, thereby avoiding short circuit accidents.

[0042] Specifically, the number of support structures 202 is equal to the number of cables, ensuring that the support structures 202 and cables correspond one-to-one. Only one cable passes through each support structure 202, so there is a gap between any two cables that prevents them from contacting each other, thus fully avoiding the occurrence of short circuit accidents.

[0043] The arrangement of each support structure 202 can be customized according to actual needs. Specifically, each support structure 202 is arranged in a rectangular array.

[0044] In some examples, the cables are spaced apart near the isolation component 201. Due to weight and cost constraints, the isolation component 201 cannot extend continuously along the cable tray body 101. To ensure that the cables can be placed spaced apart at various points along the length direction as much as possible, several isolation components 201 are arranged side by side, and the cables pass through each isolation component 201 sequentially.

[0045] Furthermore, the area between adjacent isolation components 201 defines a confinement space 203, and it is understood that there are several confinement spaces 203. The confinement space 203 is used to prevent harmful animals such as rats from adversely affecting the cable. Rats that burrow into the cable tray body 101 will gnaw on the surface of the cable, causing damage to the surface of the cable, which is one of the causes of leakage or even short circuit accidents.

[0046] Specifically, when a mouse accidentally crawls into the cable tray body 101, the mouse will be in a single confinement space 203. Since the distance between adjacent isolation components 201 is relatively small, that is, the volume of the confinement space 203 is small, it can effectively limit the range of movement of the mouse. The mouse can only damage the cable in a very small area, and will not cause damage to many parts of the entire cable, thereby limiting the severity of leakage.

[0047] In addition, since there is a gap between any two cables, even if a rat damages multiple cables within a single confined space 203, the damaged parts of the positive and negative cables will not come into contact with each other, thus avoiding short circuit accidents.

[0048] In some examples, the cable tray body 101 and the isolation component 201 are detachably connected by a plug-in connection. Specifically, a plug-in assembly is provided between the cable tray body 101 and the isolation component 201, and the isolation component 201 is plugged into the interior of the cable tray body 101 through the plug-in assembly.

[0049] In some examples, such as Figure 2 As shown, the plug-in assembly includes a slot 301 and a receiving groove 302, both of which are fixedly disposed on the inner wall of the cable tray body 101. Specifically, the slot 301 is disposed on the inner side wall of the cable tray body 101, while the receiving groove 302 is disposed on the inner bottom wall of the cable tray body 101. Correspondingly, the plate-shaped isolation member 201 also has side edges and a bottom edge.

[0050] It is understandable that the slot 301 and the receiving groove 302 are at a certain angle. When the longitudinal section of the cable tray body 101 is roughly rectangular, the slot 301 and the receiving groove 302 are approximately perpendicular. At this time, the isolation member 201 is also roughly formed as a rectangular plate structure, and the side edges and bottom edges of the isolation member 201 are also approximately perpendicular.

[0051] In this design, slots 301 and receiving grooves 302 are connected at their intersecting ends. Slots 301 are located on opposite sides of the cable tray body 101. The two side edges of the isolation component 201 are inserted into the slots 301 on both sides through the top opening of the cable tray body 101. As the isolation component 201 is inserted, its bottom edge gradually approaches the receiving groove 302 and eventually embeds itself into the interior of the receiving groove 302, completing the installation process of the isolation component 201.

[0052] In some examples, such as Figure 4 As shown, the cable tray body 101 is provided with a cover plate 401. The cover plate 401 is located at the top opening of the cable tray body 101 and is used to cover the top opening of the cable tray body 101. Thus, the cable tray body 101 and the cover plate 401 form a relatively closed space, which can prevent harmful animals such as rats from entering the interior of the cable tray body 101 and prevent rat infestation from the root.

[0053] In addition, the cover plate 401 can prevent dust, moisture and other adverse factors from corroding the cable, extend the service life of the cable, and thus improve the overall reliability of the system.

[0054] In some examples, the cover plate 401 and the cable tray body 101 are an integral structure connected to each other, with one edge of the cover plate 401 connected to the cable tray body 101. In this position, a connecting member 402 is provided between the cover plate 401 and the cable tray body 101, which allows the cover plate 401 and the cable tray body 101 to be rotatably connected. As the cover plate 401 rotates, it can close or open the top opening of the cable tray body 101.

[0055] In some examples, a locking assembly is also provided between the cover plate 401 and the cable tray body 101, which enables the cover plate 401 to close over the top opening of the cable tray body 101. It is understood that the locking assembly is located on the opposite side of the cover plate 401 where the connecting member 402 is located.

[0056] In some examples, such as Figure 5 As shown, the locking assembly includes a hook 403 and a bracket 404. The hook 403 is disposed on the cover plate 401, and the bracket 404 is disposed on the cable tray body 101. Specifically, the hook 403 is a hook, and the bracket 404 includes a ring structure. When the hook is attached to the ring structure and the ring structure pulls the hook, the cover plate 401 continuously covers the top opening of the cable tray body 101, and each cable is in a relatively enclosed space. When the hook is detached from the ring structure, the cover plate 401 is not restricted by the locking assembly, and the cover plate 401 can freely open and close the top opening of the cable tray body 101, facilitating the insertion of the isolation component 201 and the cable.

[0057] Specifically, the bracket 404 also includes a latch connecting the ring structure. The latch is used to lock the position of the ring structure and maintain the tension of the ring structure, so that the cover plate 401 continuously covers the top opening of the cable tray body 101 and prevents the cover plate 401 from being opened accidentally.

[0058] In some examples, such as Figure 6As shown, the cable tray includes a support assembly for supporting the tray body 101. The support assembly includes a bracket 501 and a support 502. The bracket 501 remains vertical, and the support 502 is angled to the bracket 501. When the cable tray body 101 needs to be placed horizontally, the support 502 is approximately perpendicular to the bracket 501, and the cable tray body 101 is connected to the support 502. When the support 502 has a certain height, the cable tray body 101 also has a corresponding certain height, which is beneficial for laying cables at a higher position.

[0059] In actual implementation, a single cable passes sequentially through the support structures 202 of several isolation components 201, ensuring that only one cable exists in each support structure 202. The remaining cables are also installed in this manner. After the cables are installed, a certain distance exists between each support structure 202, and a certain distance also exists between each cable to prevent contact between cables and to prevent short circuits. Each isolation component 201 is then plugged into the inside of the cable tray body 101 via a plug-in assembly, ensuring that each cable is also located inside the cable tray body 101.

[0060] Furthermore, the cover plate 401 on the cable tray body 101 is rotated to close the top opening of the cable tray body 101, placing each cable in a relatively enclosed space. The position of the cover plate 401 is then locked by the locking assembly to prevent the cover plate 401 from being accidentally opened. The cable tray body 101, with the cables placed on it, is finally installed on the support assembly, completing the cable laying process.
