[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer toFigure 1 - Figure 2 An embodiment provided by the utility model: An assembled sealed relay ceramic housing, including a bottom plate 1, which is used to cooperate with the connection between components and is used to cooperate with the installation of the relay. A ceramic outer shell 3 is arranged on the upper part of the bottom plate 1, which is used to protect the relay components, improve the insulation performance and weather resistance of the relay, thereby enhancing its working reliability and service life. A coating layer is arranged outside the ceramic outer shell 3. A fixing member 2 is arranged at the lower part of the outer wall of the ceramic outer shell 3, which is used to cooperate with the fixation between the ceramic outer shell 3 and the bottom plate 1. A relay body 4 is jointly arranged between the bottom plate 1 and the ceramic outer shell 3. A copper electrode 41 is fixedly connected to the top of the relay body 4, and the copper electrode 41 penetrates through the ceramic outer shell 3 and is movably connected thereto to cooperate with the installation between the ceramic outer shell 3 and the relay body 4. A hole adapted thereto is opened in the upper part of the ceramic outer shell 3.

[0033] As Figure 4 shown, a plurality of limiting blocks 11 are fixedly connected to the top surface of the bottom plate 1, and they are right-angled folding plates, which are used to limit the relay body 4 to prevent the relay from shaking in the housing. An auxiliary ring 13 is fixedly connected to the top surface of the bottom plate 1, which cooperates with a plurality of clamping petals 12 to assist in the preliminary fixation between the ceramic outer shell 3 and the bottom plate 1. Clamping petals 12 are fixedly connected to the front, rear, left, and right sides of the top surface of the bottom plate 1, and they have a certain deformation ability to cooperate with the fixing convex ring 31.

[0034] Please refer to Figure 3 - Figure 5 shown, the fixing member 2 includes a fixing sleeve 21, which is used to limit between the ceramic outer shell 3 and the bottom plate 1. A sealing ring 22 is fixedly connected to the upper part of the fixing sleeve 21 close to the ceramic outer shell 3, and it is made of rubber and is used to improve the sealing performance of the device. A fixing ring 23 is fixedly connected to the bottom of the fixing sleeve 21, which is used to cooperate with the connection between the fixing member 2 and the bottom plate 1. A screw is jointly threadedly connected between the bottom plate 1 and the fixing ring 23, so as to fix the ceramic outer shell 3 and the bottom plate 1.

[0035] Furthermore, a convex ring 31 is fixedly connected to the lower part of the outer wall of the ceramic housing 3, which is used to cooperate with the clamping flap 12 to limit the ceramic housing 3. The convex ring 31 is movably connected to the clamping flap 12, and the outside of the convex ring 31 is circular arc-shaped to facilitate the connection and disconnection with the clamping flap 12. A sealing sleeve 32 is arranged at the lower part of the inner wall of the ceramic housing 3, which is made of rubber and is used to improve the sealing performance. A positioning plate 33 is fixedly connected to the top of the inner wall of the ceramic housing 3, which is used to limit the relay body 4 to prevent the relay body 4 from shaking. A clamping groove 34 is formed in the lower part of the inner wall of the ceramic housing 3, which is used to cooperate with the connection ring 321 for connection to fix the sealing sleeve 32. A connection ring 321 is fixedly connected to the upper part of the outer wall of the sealing sleeve 32, which is made of rubber. The connection ring 321 is movably connected to the clamping groove 34. An installation opening 322 is formed in the lower part of the outer side of the sealing sleeve 32, so that a ring groove can be formed between the sealing sleeve 32 and the ceramic housing 3 for cooperating with the connection of the auxiliary ring 13.

[0036] Working principle: During use, the lower part of the relay body 4 is clamped between multiple limiting blocks 11, and then the connection ring 321 on the sealing sleeve 32 is clamped into the clamping groove 34 inside the ceramic housing 3 to fix the position of the sealing sleeve 32. Then, the ceramic housing 3 is sleeved outside the relay body 4, so that the copper electrode 41 passes through the hole on the ceramic housing 3. Then, the ceramic housing 3 is pressed towards the bottom plate 1 so that its lower part is clamped between the clamping flap 12 and the auxiliary ring 13. When the convex ring 31 is pressed down, due to its circular arc-shaped surface, it will push the upper part of the clamping flap 12 to deform, so that the convex ring 31 is clamped into the clamping flap 12, and the clamping flap 12 will reset and clamp the convex ring 31. At this time, the auxiliary ring 13 will be clamped into the ring groove formed between the installation opening 322 and the ceramic housing 3. At this time, the ceramic housing 3 is initially fixed to the bottom plate 1, and the positioning plate 33 will cooperate with multiple limiting blocks 11 to fix the relay body 4 to prevent it from shaking. Then, the fixing member 2 is sleeved outside the ceramic housing 3, so that the fixing ring 23 fits the bottom plate 1 and the sealing ring 22 closely adheres to the ceramic housing 3. Then, the fixing ring 23 and the bottom plate 1 are fixed by multiple screws.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
