[0002] Mylar sheets, as a high-performance thin film material, are widely used in multiple fields such as electronics, electrical appliances, and household appliances. Mylar sheets are mainly made of materials such as polyester, and may also include other materials such as polyvinyl chloride and polycarbonate. These materials are processed through processes such as heating, transesterification, vacuum polycondensation, and biaxial stretching with the assistance of catalysts. Mylar sheets are widely used as insulating materials for electrical equipment such as motors, capacitors, coils, and cables to ensure the safe operation of the equipment. In electronic products, mylar sheets are used to protect key components such as circuit boards and chips from the external environment. Mylar sheets play an insulating and protective role in PCB circuit boards, preventing short circuits and interference between circuits. Among them, insulation is an important property of mylar sheets.

[0004] Although the above-mentioned prior art can achieve the insulation of the Mylar sheet, in actual use, on the one hand, the functionality of the Mylar sheet is relatively single, and different situations have occurred in the working environment of electronic components, resulting in the difficulty of the Mylar sheet to protect electronic components, thereby shortening the service life of electronic components. On the other hand, the Mylar sheet is prone to damage, and it is easily damaged by interference factors in the external environment during the use of the Mylar sheet, thereby reducing the protection performance of the Mylar sheet. Therefore, it does not meet the existing requirements. For this reason, we propose an insulating Mylar sheet. Summary of the Invention

[0005] The purpose of the present invention is to provide an insulating Mylar sheet to solve the problems of relatively single functionality of the Mylar sheet and easy damage of the Mylar sheet proposed in the above background technology.

[0006] To achieve the above purpose, the present invention provides the following technical solution: an insulating Mylar sheet, including a base layer, a protective layer is arranged at the upper end of the base layer, the protective layer and the base layer are connected by glue, a protective layer is arranged at the lower end of the base layer, the protective layer and the base layer are connected by glue, and a plurality of positioning holes are arranged at the upper end of the protective layer. The positioning holes are through structures and are equidistantly distributed.

[0007] Preferably, a wear-resistant layer is arranged at the upper end inside the protective layer.

[0008] Preferably, a flame-retardant layer is arranged at the middle position inside the protective layer, and the flame-retardant layer and the wear-resistant layer are connected by glue.

[0009] Preferably, a heat-insulating layer is arranged at the lower end inside the protective layer, and the upper and lower ends of the heat-insulating layer are connected to the flame-retardant layer and the base layer by glue.

[0010] Preferably, a waterproof layer is arranged at the upper end inside the protective layer, and the upper end of the waterproof layer is connected to the base layer by glue.

[0011] Preferably, an insulating layer is arranged inside the protective layer at the lower end of the waterproof layer, the insulating layer and the waterproof layer are connected by glue, and a shielding layer is arranged inside the protective layer at the lower end of the insulating layer, and the shielding layer and the insulating layer are connected by glue.

[0012] Preferably, an adhesion layer is arranged at the lower end inside the protective layer, and the upper end of the adhesion layer is connected to the shielding layer by glue.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model can improve the protection of the mylar sheet through the shielding layer and the adhesion layer. The adhesion layer can increase the adhesion between the mylar sheet and the electronic component, so that the mylar sheet closely adheres to the outside of the electronic component, which helps to improve the firmness and stability of the fit between the mylar sheet and the electronic component. The shielding layer can prevent electromagnetic interference and reduce crosstalk. Through the shielding layer, the electromagnetic waves generated between electronic components can be effectively blocked or weakened from interfering with each other, ensuring the normal operation of the electronic device. Finally, the waterproof layer can prevent moisture from directly contacting the electronic components in a humid environment, thereby reducing the risk of short circuits in the electronic component circuits caused by moisture, and extending the service life of the electronic components.

[0015] 2. The utility model can reduce the damage of the mylar sheet during use through the wear-resistant layer and the flame-retardant layer. After the mylar sheet is installed, the wear-resistant layer provided on the outermost part of the protective layer can improve the wear resistance of the mylar sheet and prevent damage when the mylar sheet is rubbed. At the same time, the flame-retardant layer can improve the fire resistance of the mylar sheet and prevent the mylar sheet from being directly ignited in case of a fire, thus preventing all the electronic components from being ignited after a fire. Finally, the heat-insulating layer can reduce the heat transfer and prevent heat from directly transferring to the electronic components in a high-temperature environment, thereby reducing the interference of heat on the working performance of the electronic components.

[0016] 3. The utility model can make the installation of the mylar sheet more accurate by setting positioning holes. When installing the mylar sheet, first align the positioning hole at one end of the mylar sheet with the positioning structure on the electronic component, then sleeve the mylar sheet on the positioning structure, and then wrap the mylar sheet around the electronic component so that the mylar sheet covers the outside of the electronic component. At this time, the installation of the mylar sheet is completed, improving the accuracy of the mylar sheet installation, and thus improving the protection performance of the mylar sheet for the electronic component.
