Both sides of the box body 1 are provided with array-distributed heat dissipation slots 11, and both sides of the box body 1 are fixed with dust shields 12, which are correspondingly arranged on the outside of the heat dissipation slots 11, and slots for air intake and outlet of the heat dissipation slots 11 are provided below the dust shields 12. The dust shields 12 block dust on the outside of the heat dissipation slots 11, thereby reducing the entry of dust and rainwater into the heat dissipation slots 11.

[0026] A slide groove 13 is provided on both sides of the box body 1, and a U-shaped plate 14 is slidably installed in the slide groove 13. When the box body 1 is installed, the U-shaped plate 14 can be used to support or connect with the wall located on the back side of the box body 1 to stabilize and reinforce the box body 1. A base 10 is fixedly connected to the bottom of the box body 1, and an array of supporting blocks 15 are fixedly provided on the inner wall of the box body 1. The supporting blocks 15 are located on the side walls of the box body 1, and a horizontally arranged mounting rod 2 is installed on the supporting blocks 15.

[0027] like Figure 2-Figure 4 As shown, a fixing rod 23 is fixed between the two mounting rods 2, the wiring terminal is installed on the fixing rod 23, a second slide groove 22 is opened on the mounting rod 2, a threaded hole 24 is opened on one side of the second slide groove 22, and the fixing rod 23 is slidably installed in the second slide groove 22.

[0028] Both ends of the mounting rod 2 are provided with a card slot 21, which is connected to the supporting block 15. A through slot 16 is provided in the supporting block 15, and symmetrically distributed top blocks 18 are slidably installed in the through slot 16. A top spring 17 is fixedly connected between the two top blocks 18. Under the elastic force of the top spring 17, the two top blocks 18 will cooperate with the card slot 21 to fix the two ends of the mounting rod 2, so that the mounting rod 2 is horizontally installed in the box body 1.

[0029] In this embodiment, the installation position of the mounting rod 2 is adjustable. After the electrical components are installed on the back panel in the box 1, the position of the mounting rod 2 is adjusted according to actual conditions, thereby effectively adjusting and managing the installation area in the box 1 and reducing installation interference between components.

[0030] A V-shaped plate 19 is provided on the top of the box body 1, and symmetrically distributed dust collecting grooves 101 are opened in the base 10. The air inlet of the dust collecting groove 101 is attached to the lower part of the inner wall of the box body 1, and one side of the dust collecting groove 101 is connected to the air outlet groove 102. A dust filter net 104 is fixedly provided between the dust collecting groove 101 and the air outlet groove 102, and the air flow that has filtered out dust flows from the dust collecting groove 101 to the air outlet groove 102. A rectangular groove 103 is provided on the base 10 and below the mounting rod 2. A fan is fixedly installed in the rectangular groove 103, and a motor for driving the fan is fixedly provided in the rectangular groove 103. The fan and the motor are not shown in the figure.

[0031] The rectangular groove 103 is connected to the air outlet groove 102, and after the motor is started, it drives the fan to work, blowing the clean air in the air outlet groove 102 upward to cool the electrical components in the box body 1, and the airflow can stably blow through the mounting rod 2 to dissipate the heat of the components on the mounting rod 2, and then the airflow will flow from the middle of the box body 1 to the side wall of the box body 1 under the guidance of the V-shaped plate 19. The airflow can be discharged through the heat dissipation groove 11, and can also flow downward along the side wall of the box body 1 into the dust collecting groove 101 to collect the dust particles in the airflow, and make the airflow pass through the air outlet groove 102 back to the rectangular groove 103, forming a circulating heat dissipation.

[0032] like Figure 5 , Figure 6 As shown, both ends of the fixing rod 23 are provided with matching grooves 25, and the matching grooves 25 are slidably connected with the sliding grooves 22 on the mounting rod 2. The end of the fixing rod 23 is provided with a limiting hole 26, and the bolt passes through the threaded hole 24 and cooperates with the limiting hole 26, so that the fixing rod 23 is tightly installed on the mounting rod 2, and the end of the fixing rod 23 is provided with a connecting groove 27. After the ends of the two fixing rods 23 are fitted together, the two connecting grooves 27 are aligned, and the locking blocks 28 are simultaneously inserted into the two connecting grooves 27, so that the two fixing rods 23 can be connected and fixed.

[0033] Working principle:

[0034] First install the components on the back panel inside the terminal box, and then select the number and length of the fixing rods 23 according to actual needs. After the ends of the two fixing rods 23 are abutted, they can be connected and fixed by the locking block 28, and then the terminals and other components are installed on the fixing rods 23, and then the installation rod 2 is installed on the end of the fixing rod 23.

[0035] After moving the mounting rod 2 into the terminal box, select a suitable installation position, and clip the end of the mounting rod 2 onto the supporting block 15. When the supporting block 15 is connected and fixed to the mounting rod 2, move the fixing rod 23 to move the terminal to the corresponding installation position, and then perform the terminal wiring operation, and connect and fix the fixing rod 23 to the threaded hole 24 with bolts to complete the position fixation of the terminal.

[0036] Then install the transformer terminal box in the working position, and the U-shaped plate 14 assists in supporting and fixing the transformer terminal box to improve the installation firmness of the terminal box. During actual use, the fan rotates to circulate and dissipate heat for the components in the transformer terminal box. The heat dissipation groove 11 on the side wall of the box body 1 exchanges gas to reduce the air flow temperature in the box, effectively dissipate heat for the components in the box, and ensure the working temperature of the electrical components inside the terminal box.
