[0002] In the field of electrical appliance manufacturing, insulating boards serve as key components, bearing the important responsibility of isolating electric current and protecting electrical components from short-circuit and electric shock risks. Traditional insulating boards often adopt a single-layer or simple laminated structure, which exposes a series of problems in practical application. The primary problem lies in the difficulty of ensuring the tight combination between layers, as interlayer sliding and separation phenomena occur frequently, which not only weakens the insulation performance but also reduces the anti-deformation ability of the insulating board, affecting the stability and safety of electrical appliances. Especially in harsh environments such as high temperature and high pressure, the structural stability problem of traditional insulating boards is particularly prominent, becoming a bottleneck restricting the performance improvement of electrical appliances.

[0003] In addition, the installation method of traditional insulating boards is relatively cumbersome. Due to the lack of effective positioning and fixing mechanism, additional fasteners or complex operation steps are often required during installation, which not only increases the installation cost but also reduces the installation efficiency. Especially in the case of limited internal space and compact component layout of electrical appliances, the installation of traditional insulating boards becomes a challenge, affecting the flexibility and production efficiency of electrical appliance manufacturing.

[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0027] As Figures 1-7 Indicated, the utility model provides a kind of multilayer combined insulation board, which combines excellent insulation performance, thermal insulation performance and structural stability, suitable for various high-efficiency insulation and thermal insulation power equipment. Its structure is mainly composed of insulation plate body 1 and frame 2, wherein, frame 2 is used to install the insulation plate body 1 in specified position.

[0028] Insulation plate body 1 adopts laminated structure, and the specific structure is sequentially laminated with lower protective layer 101, lower insulation layer 102, thermal insulation layer 103, upper insulation layer 104 and upper protective layer 105 from bottom to top. Each layer is fixed by environment-friendly adhesive, to ensure the close combination between layers, improve the stability and durability of overall structure.

[0029] The thermal insulation layer 103 is a polystyrene foam layer or a polyurethane foam layer. The polystyrene foam layer has good thermal insulation performance and light weight, and is suitable for electrical appliances with weight restrictions. The polyurethane foam layer has higher thermal insulation performance and strength, and is suitable for electrical appliances with higher thermal insulation requirements. The upper and lower insulation layers 104 and 102 are one of a polyvinyl chloride layer, a polyethylene layer, and a glass fiber reinforced plastic layer. The polyvinyl chloride layer is commonly used as an insulation layer in low-voltage electrical appliances due to its excellent physical, mechanical, and insulating properties, as well as its low cost. The polyethylene layer is also a common insulating material with good electrical insulation performance and heat resistance. The glass fiber reinforced plastic layer has high mechanical strength and impact resistance, and is also commonly used as an insulation layer in electrical appliances. The upper and lower protective layers 105 and 101 are one of a polypropylene layer, a polyethylene layer, and a chlorobutyl rubber layer. The polypropylene layer has good corrosion resistance and wear resistance, and is commonly used as an outer protective layer in electrical appliances. The polyethylene layer also has good corrosion resistance and processing performance, and is also commonly used as an outer protective layer in electrical appliances. The chlorobutyl rubber layer has oil resistance, water resistance, and aging resistance, and is suitable for outer protective layers in electrical appliances in some special environments.

[0030] When the thermal insulation layer 103 is connected with the insulation layers on both sides, the upper surface of the thermal insulation layer 103 is provided with an upper concave-convex surface 106 that matches the connection with the upper insulation layer 104. The two are tightly fitted through the upper concave-convex surface 106 when connected, increasing the contact area between the layers and improving the connection strength. Correspondingly, the lower surface of the thermal insulation layer 103 is provided with a lower concave-convex surface 107 that connects with the lower insulation layer 102. The two are tightly fitted through the lower concave-convex surface 107 when connected, increasing the contact area between the layers and improving the connection strength.

[0031] When the protective layer is connected with the corresponding insulation layer, the upper protective layer 105 has a number of upper protrusions 108 on the side close to the upper insulation layer 104. These upper protrusions 108 are precisely embedded in the upper grooves 110 pre-set inside the upper insulation layer 104, achieving firm fixation. Similarly, the lower protective layer 101 has lower protrusions 109 on the side close to the lower insulation layer 102. These lower protrusions 109 are also precisely embedded in the lower grooves 111 pre-set inside the lower insulation layer 102.

[0032] The frame 2 is composed of a number of surrounding pieces 201 that can be connected end to end. These surrounding pieces 201 are tightly attached to the outer side of the insulation board body 1, providing additional protection and support for the insulation board body. The two ends of the surrounding pieces 201 protrude out of the edges of the upper and lower protective layers 105 and 101, respectively, ensuring that the edges of the entire insulation board are fully protected.

[0033] The surrounding piece 201 is provided with a plurality of protruding limiting insertion blocks 202 on one side close to the insulating plate body 1, the limiting insertion blocks 202 are respectively inserted and fixed in the pre-set limiting insertion slots 112 outside the upper insulating layer 104 and the lower insulating layer 102, the stable connection between the surrounding piece 201 and the insulating plate body 1 is ensured, and the surrounding piece 201 is fixed close to the outer side of the insulating plate body 1.

[0034] A plurality of mounting holes 203 are arranged on both ends of the surrounding piece 201 protruding the upper protective layer 105 and the lower protective layer 101, the mounting holes are convenient for fixing the insulating plate in a required position by using bolts, screws and other fasteners, and the flexibility and convenience of installation are improved.

[0035] Compared with the traditional technology, the insulating plate body 1 is designed through precise lamination and a unique connecting structure, the close combination between layers is ensured, the interlayer sliding and separation are effectively prevented, and the anti-deformation ability of the insulating plate body is enhanced. The stable structure not only improves the stability of the overall structure, but also improves the insulation performance, and ensures the safe operation of the electrical appliance in a high-temperature and high-pressure environment. The insulating plate body 1 can be quickly positioned and fixed in a specified position in the electrical appliance through the frame 2, the limiting insertion blocks 202 are combined with the limiting insertion slots 112, the installation steps are greatly simplified, and the installation efficiency is improved.
