[0020] In order to make the purpose and advantages of the present utility model more clear and understandable, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0021] As Figures 1 - 4 shown, a wiring terminal structure for electrical installation includes a plurality of wiring terminal bodies 1. A threaded rod 2 is threadedly connected to the bottom of the inner cavity of each wiring terminal body 1. A wire 3 is installed on one side where the wiring terminal body 1 and the threaded rod 2 are close to each other. A cleaning component and a protection component are provided on the wiring terminal body 1.

[0022] Among them, the wiring terminal body 1 is used to connect the wire 3 in the circuit to ensure the stable transmission of current and signals. The design of the wiring terminal body 1 enables it to firmly clamp the wire 3 to prevent the wire 3 from loosening or falling off. At the same time, the cooperation of the wiring terminal body 1 and the threaded rod 2 can adjust the tightening degree of the wiring terminal body 1 to adapt to wires 3 of different thicknesses. The design of multiple wiring terminal bodies 1 allows the selection of an appropriate number for installation according to specific requirements, so as to meet diverse electrical connection needs; when the wiring terminal body 1 is in use, it may come into contact with various substances, resulting in the generation of dirt. Whether indoors or outdoors, dust in the air may gradually accumulate on the surface of the wiring terminal body 1. The cleaning component is provided to clean the inner wall of the wiring terminal body 1 and can effectively remove the accumulated dust.

[0023] As Figure 2 and Figure 3 shown, the cleaning component includes first slide rails 4 fixedly connected to both sides of the top of the wiring terminal body 1. First sliders 5 are slidably connected to the inner sides of the two first slide rails 4. A scraper 6 is fixedly connected to the tops of the two first sliders 5. Second chutes 7 are fixedly connected to both sides of the bottom of the inner cavity of the wiring terminal body 1. Second sliders 8 are fixedly connected to both bottoms of the scraper 6, and the surface of the second slider 8 is slidably connected in the second chute 7. A round hole 9 is opened on one side of the wiring terminal body 1. A push rod 10 is inserted into the round hole 9, and one end of the push rod 10 is fixedly connected to one side of the scraper 6. A first spring 11 is fixedly connected to the side where the scraper 6 and the push rod 10 are close to each other.

[0024] Specifically, manually pushing the push rod 10 drives the scraper 6 to slide through the first slider 5 in the first slide rail 4, so that the scraping strips 12 on both sides of the scraper 6 are attached to the inner walls on both sides of the terminal block body 1, cleaning the inner walls of the terminal block body 1 and effectively removing the accumulated dust. At the same time, the bottom of both sides of the scraper 6 is slidably connected to the second chute 7 through the second slider 8, which can increase the stability of the scraper 6 moving in the terminal block body 1 and prevent the scraper 6 from shifting during the sliding process, further improving the cleaning effect. After the cleaning is completed, using the resilience of the first spring 11, the bottom of the scraper 6 slides through the second slider 8 in the second chute 7, and at the same time, the top of the scraper 6 slides through the first slider 5 in the first slide rail 4 until the scraper 6 is reset, completing the cleaning work and avoiding the accumulation of dust.

[0025] As Figure 4 shown, scraping strips 12 are fixedly connected to both sides of the scraper 6, and both sides of the scraping strips 12 are of an inclined structure.

[0026] Among them, the scraping strips 12 on both sides of the scraper 6 can effectively clean both sides of the inner wall of the terminal block body 1 through displacement without damaging the inner wall of the terminal block body 1. The inclined structure design enables the scraping strips 12 to slide more closely when attached to the inner wall of the terminal block body 1, avoiding dead corners during the cleaning process and improving the cleaning efficiency.

[0027] As Figure 2 and Figure 3 shown, the protection component includes a protection cover 13 fixedly connected to the top side of the scraper 6 close to the first spring 11, and the bottom of the protection cover 13 is attached to the top of the terminal block body 1. A plug block 14 is fixedly connected to one side of the first slider 5 and inside the first slide rail 4. One end of the first slide rail 4 is fixedly connected to a fixed block 15. A plug rod 16 is inserted into the top of the fixed block 15. A second spring 17 is fixedly connected to the side of the top of the fixed block 15 close to the plug rod 16, and the second spring 17 is sleeved on the surface of the plug rod 16.

[0028] Specifically, manually push the push rod 10 to move the protective cover 13 to the top of the terminal block body 1 through the movement of the scraping plate 6, so as to protect the top of the terminal block body 1 and prevent dust from entering from the top of the terminal block body 1. When the scraping plate 6 drives the protective cover 13 to cover the opening at the top of the terminal block body 1, manually pull the insertion rod 16 upward to dock the insertion block 14 with the fixed block 15, and use the resilience of the second spring 17 to insert the insertion rod 16 into the insertion block 14 and the fixed block 15 to limit and fix the scraping plate 6 and the protective cover 13, so as to stably protect the opening of the terminal block body 1; when the protection needs to be removed, just manually stretch the insertion rods 16 on both sides of the top of the terminal block body 1 upward and make the insertion rods 16 disengage from the insertion block 14 and the fixed block 15, and then drive the scraping plate 6 and the protective cover 13 to reset through the resilience of the first spring 11, and the opening of the terminal block body 1 can be exposed, which is convenient for subsequent operations, and can effectively prevent dust and other impurities from entering the inside of the terminal block body 1, ensuring the safety and stability of electrical connections.

[0029] As Figure 3 shown, two strip-shaped rods 18 are fixedly connected to one side opening of the terminal block body 1, and a collection groove 19 is inserted on the surfaces of the two strip-shaped rods 18.

[0030] Among them, the matching design of the strip-shaped rod 18 and the collection groove 19 is convenient for collecting the dust and dirt scraped off from the inner wall of the terminal block body 1 by the scraping plate 6. When the scraping plate 6 moves on the inner wall of the terminal block body 1, the attached dust and dirt can be scraped off, and the scraped dust and dirt will fall into the collection groove 19. The user only needs to regularly clean the dust and dirt in the collection groove 19, effectively keeping the terminal block body 1 clean.

[0031] As Figure 1 shown, an arched groove is provided on one side of the scraping plate 6, and the cross-section of the protective cover 13 is in a T-shaped structure.

[0032] Specifically, the design of the arched groove enables the scraping plate 6 to move more smoothly, reducing the friction with the threaded rod 2 and the wire 3 at the bottom of the terminal block body 1; the T-shaped protective cover 13 can fit with the top of the terminal block body 1, enhancing the protection effect of the top of the terminal block body 1.

[0033] The working principle of the present utility model is as follows: First, manually push the push rod 10 to drive the scraping plate 6 to slide through the first slider 5 in the first slide rail 4. At the same time, the bottom sides of both sides of the scraping plate 6 are slidably connected to the second slide grooves 7 through the second sliders 8, so that the scraping strips 12 on both sides of the scraping plate 6 are attached to the inner walls on both sides of the terminal block body 1, and the inner wall of the terminal block body 1 is cleaned. Then, when the scraping plate 6 drives the protective cover 13 to cover the opening at the top of the terminal block body 1, manually pull the insertion rod 16 upward to dock the insertion block 14 with the fixed block 15, and use the resilience of the second spring 17 to make the insertion rod 16 inserted into the insertion block 14 and the fixed block 15 to limit and fix the scraping plate 6 and the protective cover 13, so as to stably protect the opening of the terminal block body 1. Finally, use the collection groove 19 to collect the dust cleaned by the scraping plate 6, and thus complete the cleaning and protection of the inner wall of the terminal block body 1.

[0034] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
