[0029] The present invention is further described in detail below in conjunction with embodiments. The following embodiments are for explanation of the present invention but the present invention is not limited to the following embodiments.

[0030] Example 1

[0031] Cable trays are used to lay cables to make the cable layout simple and easy to inspect and maintain.

[0032] like Figure 1 , Figure 2 , Figure 3 The cable tray includes a tray body 2 having a receiving cavity 1 and a cover plate 3 arranged on the tray body 2 to cover the receiving cavity 1. The tray body 2 and the cover plate 3 are both made of metal plates, and the metal plates used to make the cover plate 3 have a certain elastic deformation ability.

[0033] Through holes are evenly distributed on the bridge body 2, and the through holes are connected to the accommodating cavity 1. The through holes can be circular or in other shapes. The through holes can dissipate heat and reduce the manufacturing cost of the bridge.

[0034] The bridge body 2 is provided with a positioning groove 4 for positioning the cover plate 3, and the positioning groove 4 can be made by stamping. The positioning groove 4 is recessed into the accommodating cavity 1. The cover plate 3 includes a folded edge 5, which is formed by bending the cover plate 3. A positioning edge 6 cooperating with the positioning groove 4 is provided on the folded edge 5.

[0035] like Figure 1 , Figure 2 , Figure 3 The positioning edge 6 is formed by bending the folded edge 5, that is, the positioning edge 6 is formed by stamping the folded edge 5. A notch 7 is provided on the folded edge 5 to facilitate the elastic deformation of the folded edge 5. Notches 7 are provided in the extending direction of both ends of one positioning edge 6 to facilitate the elastic deformation of the folded edge 5 where the positioning edge 6 is provided.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 A spring sheet 8 is also provided on the folded edge 5 , and the spring sheet 8 includes a fixed end and a free end. The spring sheet 8 spans the notch 7 , and the fixed end is welded to the folded edge 5 on the side of the notch 7 away from the positioning edge 6 .

[0037] Strip holes are evenly distributed on the cover plate 3 . The strip holes are arranged along the width direction of the cover plate 3 . The strip holes have the function of heat dissipation. Moreover, the arrangement of the strip holes can also reduce the manufacturing cost of the cover plate 3 .

[0038] The arrangement of the positioning grooves 4 and the positioning edges 6 in this solution facilitates the assembly of the cover plate 3 and the cable tray body 2, simplifies the structure of the cable tray, and reduces the use cost of the cable tray.

[0039] Example 2

[0040] This embodiment introduces a possible structure of the bridge body 2, which can be combined with Embodiment 1.

[0041] like Figure 1, Figure 3 A partition 9 is provided in the accommodating cavity 1 to separate the accommodating cavity 1. The partition 9 is provided along the length direction of the accommodating cavity 1. The partition 9 is formed by bending the bridge body 2. The height of the partition 9 is less than the depth of the accommodating cavity 1. A heat insulating layer 10 is provided in the partition 9. The heat insulating layer 10 is a structure with heat insulating capability, and the heat insulating layer 10 is provided when the bridge body 2 is bent.

[0042] Holes are evenly distributed on the partition 9 , and the holes penetrate the partition 9 and the heat insulation layer 10 . The hole is in the shape of a long strip, and the hole is arranged along the height direction of the partition 9 .

In the actual power supply process, the power circuit is prone to generate heat, which may damage the insulation performance of the control circuit. The heat insulation capacity of the partition 9 and the isolation plate 11 can prevent the heat energy emitted by the power circuit from damaging the insulation performance of the control circuit, thereby optimizing the performance of the cable tray.
