[0002] Switch box, also known as distribution cabinet, distribution board, distribution box, is a device for concentrating, switching and distributing electric energy. Switch box is generally composed of cabinet, switch (circuit breaker), protection device, monitoring device, electric energy meter, and other secondary components. According to the current, it can be divided into AC and DC switch box. According to the voltage, it can be divided into lighting switch box and power switch box, or high voltage distribution board and low voltage distribution board. DC electrical switch box is one of the necessary power equipment on modern ships. Most of the existing ship electrical switch boxes are fixedly connected to the hull, which is inconvenient to adjust.

[0003] However, in the prior art, the electrical switch box is generally installed in the engine room of the ship, close to the main electrical equipment, so as to facilitate the control and monitoring of the equipment. There are many mechanical equipment running in the engine room, and the vibrations and airflows generated may cause dust in the surrounding environment to be raised. Moreover, the ventilation system in the engine room may also carry a certain amount of dust into the vicinity of the switch box during the air circulation process, resulting in dust being brought into the switch box when the switch box is dissipated, affecting the electrical equipment.

By providing a fixing mechanism 5, after the cable is connected and fixed to the electrical equipment inside the box 1, the two pads 58 can be loosened, and the squeezed springs 59 are released, so that the multiple arc-shaped clamping plates 57 on the two clamping plates 56 are close to each other to fix the cable, and then the cable is arranged and installed in an orderly manner inside the box 1, which greatly improves the wiring efficiency, avoids the entanglement and confusion of the cable, and effectively saves space.

[0040] A specific application of this embodiment is: by providing a heat dissipation mechanism 2, the vent 1 21, the exhaust fan 23 and the vent 2 24 cooperate with each other, so that the exhaust fan 23 can draw the air inside the box 1 through the top vent 1 21, and the bottom vent 1 21 and the vent 2 24 on both sides serve as air inlets, forming an air circulation to dissipate heat for the electrical equipment inside the box 1, and the filter plate 1 22 and the filter plate 2 25 can filter the air in advance to prevent dust in the air from flowing into the interior of the box 1 and affecting the electrical equipment, and avoid excessive temperature when the electrical equipment is running, which greatly improves the service life of the equipment and reduces safety hazards.

When the connecting rod 21 moves backward, the angle between the hinged plate 1 42 and the hinged plate 2 43 will change. At this time, the top rod 1 44 will move away from the filter plate 1 22. When the connecting rod 21 moves forward and resets, the top rod 1 44 will approach the filter plate 1 22 and slightly hit the bottom surface of the filter plate 1 22, so that the dust attached to the bottom surface of the filter plate 1 22 can be vibrated off. When cleaning the two filter plates 25, the filter plate 1 22 can also be cleaned, thereby ensuring the continuous and efficient operation of the filter plates 1 22 and the filter plates 2 25, extending the service life of the filter plates 1 22 and the filter plates 2 25, and providing reliable protection for the entire filtering system.

[0042] By providing the fixing mechanism 5, before connecting the cable, the pad 58 can be pulled to make the two clamping plates 56 in the same fixing frame 54 move away from each other.

The rubber ring 53 is composed of four fan-shaped rubber sheets, and the four fan-shaped rubber sheets are fixed on the inner wall of the connecting ring 52 through the outer ring edge. After the cable squeezes the four fan-shaped rubber sheets and passes through the inside of the connecting ring 52, the fan-shaped rubber sheets will be in close contact with the outer wall of the cable to prevent external dust from invading the inside of the box 1 through the opening 51. After the cable is connected and fixed to the electrical equipment inside the box 1, the two pads 58 can be loosened, and the extruded spring 2 59 is released, so that the multiple arc clamping plates 57 on the two clamping plates 56 are close to each other to fix the cable, and then the cables are arranged and installed in an orderly manner inside the box 1, which greatly improves the wiring efficiency, avoids the entanglement and confusion of the cables, and effectively saves space.
