Description

Technical Field

[0001] This utility model relates to the technical field of temporary protection for electrical boxes, specifically to a dust protection device for electrical boxes. Background Technology

[0002] The electrical distribution box, also known as the main electrical box, is an electrical box used in home renovations to centrally install and manage high-voltage electrical system equipment. As the distribution center of the power system, it receives electrical energy from the power source and distributes it to various electrical devices and circuits within the building. Through the distribution box, electricity can be transmitted to different areas or devices as needed. Dust can obstruct the normal flow of current, increase circuit resistance, leading to insufficient current flow or even overheating and malfunctions. Excessive dust can also adhere to electrodes, causing poor contact, overheating, and burning out the electrodes. Moisture-soaked dust can also cause discharge, resulting in unstable voltage. During renovations, external wiring is often connected to the distribution box, preventing the box cover from closing completely. Dust can easily enter the distribution box during renovations, causing the aforementioned problems. Therefore, we propose… Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0020] like Figure 1-3As shown, this utility model discloses a dustproof protection device for an electrical box, including an inner shell 7 of the electrical box, an electrical switch group 8 arranged inside the inner shell 7, a cover plate 1 detachably installed at the front end of the inner shell 7 by bolts, a boss 2 integrally formed in the middle of the surface of the cover plate 1, and a plurality of baffles 6 fixedly arranged at equal intervals on the surface of the boss 2, the baffles 6 including a metal baffle group 601 and a plastic baffle group 602 arranged in parallel front and rear, and a dust filter core 9 filled between the metal baffle group 601 and the plastic baffle group 602.

[0021] Example 1: The protrusion height of the boss 2 is consistent with the protrusion thickness of the electrical switch assembly 8. Both the metal baffle group 601 and the plastic baffle group 602 are composed of multiple equally spaced metal and plastic columns. The spacing between the metal and plastic columns is set to 2mm. After the boss 2 is attached to the electrical switch assembly 8, the metal baffle group 601 and the plastic baffle group 602 are cut according to the position and total span of the electrical switch assembly 8 to cut out slots that match the position and total span of the electrical switch assembly 8, so as to operate the electrical switch assembly 8. Then, a dust filter core 9 of the appropriate size is filled between the metal baffle group 601 and the plastic baffle group 602 to achieve dust protection for the inner shell of the electrical box. At the same time, the dust filter core allows airflow to pass through, ensuring the heat dissipation of the foundation.

[0022] When it is necessary to temporarily connect an external wire to the power terminal of the electrical switch group 8, the cover 5 can be opened, and the wire end can be passed through the through hole 4 to temporarily connect to the power terminal of the electrical switch group 8. This is suitable for temporary power supply scenarios during decoration.

[0023] In the preferred technical solution, the cover plate 1 includes a metal panel 101 and a plastic panel 102, with the metal panel 101 located on the surface of the cover plate 1 and the plastic panel 102 located on the inner layer of the cover plate 1.

[0024] In the preferred technical solution, a number of through holes 4 are horizontally and equidistantly opened at the bottom end of the cover plate 1. A cover 5 is rotatably installed on the outside of the through holes 4 through a hinge. The cover plate is divided into an outer metal layer and an inner plastic insulation layer, which ensures insulation safety while increasing the impact resistance of the cover plate.

[0025] In the preferred technical solution, the surface of the boss 2 is made of magnetic metal, and a shield 3 is magnetically installed on the surface of the boss 2. The shield 3 is used to shield the electrical switch group 8 to reduce accidental contact.

[0026] In the preferred technical solution, the mask 3 includes a magnetic frame and a filter mesh fixed inside the magnetic frame. The magnetic frame of the mask 3 can be easily matched with the magnetic metal material on the surface of the boss 2 to fix the mask 3.

[0027] In summary, based on the position and total span of the electrical switch group 8, the metal baffle group 601 and the plastic baffle group 602 are cut to create slots that match the position and total span of the electrical switch group 8, facilitating the operation of the electrical switch group 8. The baffle 6 is filled with a dust filter core 9 of the appropriate size to achieve dust protection for the inner shell of the electrical box. At the same time, the dust filter core allows airflow to pass through, ensuring heat dissipation of the foundation. When it is necessary to temporarily connect external wires to the electrical switch group 8, the cover 5 can be opened, and the wire end can pass through the through hole 4 to temporarily connect to the electrical switch group 8. This is suitable for temporary power supply scenarios during decoration. This embodiment provides a dust protection device that can be adjusted on-site according to the position and total span of the electrical switch group 8, for dust protection of the inside of the power distribution box during decoration.
