[0001] This application relates to the field of Mylar sheet technology, and in particular to an easily installable insulating Mylar sheet assembly. Background Technology

[0002] Insulating Mylar sheets have wide applications in electronics, electrical appliances, motors, transformers, and communications. In electronics, they can be used for insulation between circuit board layers and between components and boards, as well as for gaskets in electrical appliance housings. In the motor and transformer industry, they can wrap windings for insulation and withstand heat and vibration. In the communications industry, they can isolate signal lines and enhance cable insulation to resist interference. They can be installed in various ways: cut to suitable shapes and sizes and placed where insulation is needed, or stamped into specific shapes and installed in corresponding positions. They can also be combined with other materials and, depending on the composite properties and application, installed on the outer layer of corresponding equipment or cables through methods such as adhesive bonding or wrapping to perform insulation and other functions.

[0003] Traditional insulating Mylar sheets are typically fixed to electronic components using simple adhesive methods, which presents several inconveniences. Firstly, during installation, it's difficult to accurately determine the Mylar sheet's position, leading to misalignment or displacement that affects the performance and stability of the electronic equipment. Secondly, when replacing or repairing the Mylar sheet, its strong adhesion makes disassembly extremely difficult, often damaging the electronic component or the Mylar sheet itself, increasing maintenance and time costs. Furthermore, traditional Mylar sheets lack flexibility in adapting to electronic components of different sizes, failing to meet diverse production needs. Therefore, there is an urgent need for a new type of insulating Mylar sheet assembly to solve these problems and improve the efficiency and quality of electronic equipment production and maintenance.

[0020] In the accompanying drawings, for clarity, the dimensions of layers, areas, and elements, as well as their relative dimensions, may be exaggerated. The same reference numerals denote the same elements throughout.

[0021] It should be understood that when an element or layer is referred to as "on," "adjacent to," "connected to," or "coupled to" other elements or layers, it may be directly on, adjacent to, connected to, or coupled to other elements or layers, or there may be intervening elements or layers.

[0024] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0025] This invention relates to an easily installable insulating Mylar sheet assembly, and its specific embodiments will be described in detail below so that those skilled in the art can clearly understand and implement the invention.

[0026] like Figures 1 to 5 As shown, including, The mela sheet body includes several functional layers; in this embodiment, the projection of the mela sheet body onto the horizontal plane is rectangular.

[0027] An adhesive layer 2 is disposed on the lower surface of the Mylar sheet body, and an anti-adhesion layer 3 is adhered to the lower surface of the adhesive layer; the surface of the adhesive layer is coated with adhesive for bonding the substrate and electronic components. The anti-adhesion layer can be separated from the adhesive layer during use.

[0028] A detachable structure is provided at the four corners of the Mylar sheet body. The detachable structure includes four positioning components 4. Each positioning component has a slot 41. The edge of the Mylar sheet body is inserted into the slot. Before the Mylar sheet is attached, each corner of the Mylar sheet is inserted into the slot of the positioning component. The above-mentioned surface of each positioning component is provided with a positioning accessory 5. The positioning accessory includes two mutually perpendicular positioning rods 51, with a positioning block 52 slidably connected to each positioning rod. A fixing part 53 is fixedly installed on the side of the positioning block near the positioning assembly, and the fixing part is used to contact the electronic component. In use, the position of the positioning block relative to the positioning rod in the positioning accessory is adjusted according to the position where the Mylar sheet needs to be attached, and the fixing part on the inner side of the positioning block is made to fit against the side wall of the electronic component to achieve the positioning of the Mylar sheet.

[0029] Furthermore, each positioning component is detachably connected to a connecting plate 42. The upper surface of the connecting plate abuts against the anti-adhesion layer, and there is a first preset distance between the connecting plate and the edge of the Mylar sheet body. In this embodiment, the connecting plate is used to fix the two positioning components on the same side of the Mylar sheet body, ensuring the stability of the connection between the positioning components and the Mylar sheet body. After the positioning accessories complete the positioning of the Mylar sheet body, the connecting plate can be removed to facilitate the removal of the positioning components. The first preset distance is between 1 / 4 and 1 / 5 of the width of the Mylar sheet body.

[0030] Furthermore, the edge of the connecting plate is provided with a cutting portion for cutting the anti-adhesion layer. When removing the anti-adhesion layer, the cutting portion is used to cut the anti-adhesion layer located outside the connecting plate to expose the corresponding adhesive layer when the Mylar sheet is attached. The Mylar sheet is pre-positioned by adhering to the electronic component through the area of ​​the adhesive layer. After removing the entire positioning assembly, the remaining anti-adhesion layer is removed to complete the attachment of the Mylar sheet to the electronic component.

[0031] Furthermore, the lower surface of the anti-adhesion layer is provided with a semi-cut notch 31, the depth of which is half the thickness of the anti-adhesion layer, and the semi-cut notch is located directly below the sidewall of the positioning component. The semi-cut notch facilitates the tearing of the anti-adhesion layer.

[0032] Furthermore, the positioning assembly includes an upper positioning member 43 and a lower positioning member 44. The lower surface of the upper positioning member is provided with a limiting rod 431, which is inserted into a limiting hole 441 in the lower positioning member. The upper and lower positioning members are two separate main bodies. After the positioning of the Mylar sheet is completed and part of the Mylar sheet body is in place, the upper and lower positioning members can be separated, facilitating the removal of the positioning assembly. Moreover, when connecting and fixing the same type of Mylar sheet to electronic components, the removal of the positioning assembly will not affect the positioning accessories, eliminating the need for secondary adjustments to the positioning accessories.

[0033] Furthermore, the surface of the positioning rod is provided with a scale 511, the scale value of which gradually increases from the end of the positioning rod near the positioning component to the end of the positioning rod away from the positioning component. It can be understood that the scale value is determined according to the position where the Mylar film needs to be attached to the electronic component, and the position of the positioning block is determined by moving the positioning block closer to the positioning component to the corresponding scale value. Setting a scale allows for quick and accurate determination of the positioning block's position.

[0034] Furthermore, the surface of the positioning rod is uniformly provided with locking holes 512, and the positioning block has a protrusion 521 that matches the locking holes. The protrusion is placed in the locking holes, and the holes are hemispherical. It can be understood that the positioning block has a through hole that matches the positioning rod, and the positioning rod is inserted into the through hole. The protrusion is located at the end of the through hole near the positioning component. By placing the protrusion in the corresponding locking hole, the positioning block and the positioning rod can be quickly adjusted, improving the efficiency of bonding the Mylar sheet.

[0035] Furthermore, the two sidewalls of the positioning component that form the slot are obtuse angles. In actual use, the anti-adhesion layer at the three connecting plates is usually removed first, that is, the three sides of the Mylar sheet body are fixed first, and then the positioning component is removed. The positioning component is set with an obtuse angle to facilitate the removal of the anti-adhesion layer in the area originally covered by the positioning component after the positioning component is removed.

[0036] Furthermore, each side of the anti-adhesion layer is provided with an easy-tear opening 32. During installation, the easy-tear opening can be used to tear open part of the edge of the anti-adhesion layer first, and then the anti-adhesion layer can be further separated along the half-cut line, making the operation convenient and quick.

[0037] Furthermore, the functional layer includes a base layer 11 and an insulating layer 12.

[0038] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this application and do not limit the scope of protection of this patent application.
