[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figures 1 to 5 A solid-state relay that is not easy to fall off comprises a solid-state relay body 1, wherein the solid-state relay body 1 is mounted on an electrical box 2, a fixing mechanism 3 is fixedly connected to the back of the solid-state relay body 1, the fixing mechanism 3 comprises a fixing plate 301 fixed to the back of the solid-state relay body 1, a slide groove 302 is provided inside the fixing plate 301, a groove 303 is provided on the side of the fixing plate 301, the groove 303 is connected to the slide groove 302, a plurality of springs 304 are fixedly connected to the inner wall of the slide groove 302, a slider 305 is fixedly connected to the output end of the spring 304, and two symmetrically arranged fixing frames 4 are fixedly connected to the surface of the electrical box 2.

[0021] The solid-state relay that is not easy to fall off in the utility model is similar to the existing solid-state relay structure, such as the solid-state relay disclosed in the patent with announcement number CN218918862U. The main improvement of the utility model is: by setting a fixing mechanism 3 on the back of the solid-state relay body 1 and setting a fixing frame 4 on the electrical box 2 where the solid-state relay body 1 is installed to fix the fixing mechanism 3, the solid-state relay body 1 is fixed so that it is not easy to fall off during use. Figures 1 to 5 As shown, the solid-state relay that is not easy to fall off in the utility model is installed by pressing the two sliders 305 on both sides of the solid-state relay body 1, so that the slider 305 slides into the slide groove 302, and the spring 304 stores energy and is compressed, and the solid-state relay body 1 together with the fixing mechanism 3 is slowly moved downward from the top of the fixing frame 4 until the solid-state relay body 1 and the baffle 5 under the second L-shaped fixing block 402 are against each other. At this time, the spring 304 releases energy and returns to its original state, and the spring 304 pushes the slider 305 to move outward, so that the slider 305 is stuck between the first L-shaped fixing block 401 and the second L-shaped fixing block 402, so as to be fixed, and at the same time, the solid-state relay body 1 and the electrical box 2 are fixed with screws to further reinforce the solid-state relay body 1.

[0022] like Figure 4 or Figure 5As shown, there are two fixing mechanisms 3 , which are arranged symmetrically with respect to the solid-state relay body 1 .

[0023] Specifically, two symmetrically arranged fixing mechanisms 3 jointly fix the solid-state relay body 1, making the solid-state relay body 1 more stable.

[0024] like Figure 1 or Figure 2 As shown, the fixing frame 4 includes a first L-shaped fixing block 401 and a second L-shaped fixing block 402 fixed on the surface of the electrical box 2. The first L-shaped fixing block 401 and the second L-shaped fixing block 402 are symmetrically arranged up and down about the solid-state relay body 1, and there is a sufficient gap between the first L-shaped fixing block 401 and the second L-shaped fixing block 402.

[0025] Specifically, the fixing frame 4 and the electrical box 2 are integrally manufactured, and a sufficient gap is left between the first L-shaped fixing block 401 and the second L-shaped fixing block 402 of the fixing frame 4 so that when the solid-state relay body 1 is removed, the slider 305 can be pressed at the gap so that the slider 305 slides inward, and the first L-shaped fixing block 401 and the second L-shaped fixing block 402 no longer support and restrict the slider 305, and the solid-state relay body 1 can be removed by sliding upwards together with the fixing mechanism 3.

[0026] like Figure 1 As shown, the lower end of the second L-shaped fixing block 402 is fixedly connected with a baffle 5 .

[0027] Specifically, the baffle 5 can play a positioning role when installing the solid-state relay body 1 together with the fixing mechanism 3. It can slide into the gap between the first L-shaped fixing block 401 and the second L-shaped fixing block 402 without having to find the slider 305, and at the same time support the solid-state relay body 1 together with the fixing mechanism 3.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
