Description

Technical Field

[0001] This utility model relates to the field of melatonin technology, and more specifically, to a melatonin. Background Technology

[0002] Mylar film is a thin film made by heating dimethyl terephthalate and ethylene glycol under the assistance of a relevant catalyst, followed by transesterification and vacuum polycondensation, and biaxial stretching. It is widely used in the electrical insulation industry and is suitable for gaskets, baffles, screens and protection in electronics, home appliances, instruments, displays, motor slots, computers and peripherals.

[0003] Existing Mylar sheets often only protect the parts of electronic components (such as batteries and circuit boards) that come into contact with the Mylar sheet. The edges of electronic components are often not well protected. In addition, conventional Mylar sheets are usually only fixed to electronic components with glue. Some electronic components have irregular shapes and structures, so the protection effect of Mylar sheets on the edges of electronic components is often not good enough.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mela tablet.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a Mylar sheet includes a base layer, and a fixing strip is detachably connected to the edge of the base layer. The fixing strip includes a wrapping strip and several fixing pieces. The wrapping strip has elastic deformation capability, and the fixing pieces have plastic deformation capability and can be bent. The several fixing pieces are respectively fixedly connected to the two side walls of the wrapping strip. Adhesive and release paper are provided on the fixing pieces.

[0007] The present invention is further configured such that: the fixing piece is provided with a bending line, the bending line is composed of a plurality of through holes, and the through holes are located near the edge of the wrapping strip.

[0008] The present invention is further configured such that: the fixing piece is configured as a structure that is narrow at the top and wide at the bottom, the wider end of the fixing piece is fixedly connected to the wrapping strip, and the distance between adjacent fixing pieces is greater than the length of the wider end of the fixing piece.

[0009] The present invention is further configured such that the wrapping strip and several fixing pieces are integrally formed by compression molding.

[0010] The present invention is further configured such that a buffer layer is fixedly connected to the base layer.

[0011] The present invention is further configured such that a protective layer is fixedly connected to the end face of the buffer layer away from the base layer.

[0012] In summary, this utility model has the following beneficial effects: after the base layer abuts against the electronic component, the wrapping strip is made to fit the side of the electronic component by bending the fixing piece, thus protecting the edge of the electronic component. For irregular edges of the electronic component, the wrapping strip with elastic deformation capability can better fit the edge of the electronic component. Then, the fixing piece located on the other side of the wrapping strip is fixedly connected to the electronic component, thereby protecting the surface and edge of the electronic component.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] A type of melatonin, such as Figure 1 , Figure 2 and Figure 3 As shown, the system includes a base layer 3, with a fixing strip 2 detachably connected to the edge of the base layer 3. The fixing strip 2 includes a wrapping strip 201 and several fixing pieces 202. The wrapping strip 201 has elastic deformation capability, and the fixing pieces 202 have plastic deformation capability and can be bent. Several fixing pieces 202 are respectively fixedly connected to the two side walls of the wrapping strip 201. Adhesive and release paper are provided on the fixing pieces 202. The adhesive on the fixing pieces 202 can be connected to the base layer 3. After the base layer 3 abuts against the electronic component 1, the wrapping strip 201 is made to fit against the side of the electronic component 1 by bending the fixing pieces 202, thus protecting the edge of the electronic component 1. For the irregular edge of the electronic component 1, the wrapping strip 201 with elastic deformation capability can better fit against the edge of the electronic component 1. Then, the fixing pieces 202 located on the other side of the wrapping strip 201 are fixedly connected to the electronic component 1, thereby protecting the surface and edge of the electronic component 1.

[0019] like Figure 1 , Figure 2 and Figure 3As shown, the fixing piece 202 is configured with a structure that is narrower at the top and wider at the bottom. The wider end of the fixing piece 202 is fixedly connected to the edge of the wrapping strip 201. The fixing piece 202 has a bending line, which is composed of several through holes 203. The bending line is located near the wider end of the fixing piece 202. Preferably, the fixing piece 202 can be configured as two parts, namely an adhesive part and a bending part. The cross-sectional shape of the adhesive part is an isosceles trapezoid, and the cross-sectional shape of the bending part is rectangular. The bending line is located on the bending part, and the bending part is fixedly connected to the wider part of the adhesive part. The adhesive part is mainly provided so that after the wrapping strip 201 is bent, the adhesive part can better abut against the surface of the electronic component 1. For the fixing function, the bending part is designed so that the fixing piece 202 has a certain amount of leeway when bending, making the bending of the fixing piece 202 more convenient and the fit with the electronic component 1 better. Both the wrapping strip 201 and the fixing piece 202 are made of PET material and are formed by compression molding. The integral molding of the wrapping strip 201 and several fixing pieces 202 gives the fixing strip 2 good structural strength and structural integrity. Preferably, the several perforations 203 on the fixing piece 202 can be formed by laser drilling, or the perforations 203 can be formed on the fixing piece 202 by protrusions on the mold when compressing the fixing piece 202 and the wrapping strip 201.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the fixing plate 202 is provided with adhesive and release paper. After cleaning the surface of the fixing strip 2, the adhesive is evenly applied to the fixing plate 202 using tools such as a brush, scraper, and roller. After the adhesive dries, the release paper is gently attached to the surface of the adhesive. The adhesive is mainly for the fixing plate 202 to bond with the base layer 3 and the electronic component 1, and the release paper is mainly for preventing the fixing strip 2 from sticking to other objects during transportation. Preferably, adhesive and release paper are provided on both end faces of the fixing plate 202. The fixing pieces 202 are arranged linearly along the length of the fixing strip 2, and the distance between adjacent fixing pieces 202 is greater than the length of the wider end of the fixing piece 202. When encountering some electronic components 1 with irregular edges, the fixing pieces 202 that are fixedly connected to the base layer 3 are bent so that the wrapping strip 201 is bent and deformed so that it fits against the edge of the electronic component 1. The distance between adjacent fixing pieces 202 can ensure that adjacent fixing pieces 202 are not likely to overlap, thereby improving the reliability of the fit between the fixing pieces 202 and the electronic component 1.

[0021] like Figure 1 , Figure 2 and Figure 3As shown, a buffer layer 4 is fixedly connected to the base layer 3, and a protective layer 5 is fixedly connected to the end face of the buffer layer 4 away from the base layer 3. The buffer layer 4 is made of a porous and fluffy material such as sponge with a certain degree of elastic deformation. The base layer 3 and the protective layer 5 are made of materials such as PVC with good wear resistance, chemical resistance, insulation and heat resistance. The base layer 3 and the protective layer 5 utilize the properties of their materials to protect the electronic component 1. The buffer layer 4, located between the base layer 3 and the protective layer 5, can deform when the end face of the electronic component 1 covered by the base layer 3, the buffer layer 4 and the protective layer 5 is impacted by external force, and absorbs part of the impact energy by utilizing the internal porous characteristics, thereby reducing the impact force on the electronic component 1.

[0022] Working principle: When installing this Mylar sheet onto electronic component 1, first cut the base layer 3 to match the shape and size of electronic component 1. First, remove the release paper from the fixing piece 202. Then, make the wrapping strip 201 abut against the side wall of electronic component 1. Bend the wrapping strip 201 so that it fits against the protected side wall. Then, bend several fixing pieces 202 located on both sides of the wrapping strip 201 so that the fixing pieces 202 are bonded to the base layer 3 and electronic component 1 respectively. Then, the buffer layer 4 is glued to the end face of the base layer 3 away from electronic component 1. Subsequently, the protective layer 5 is glued to the buffer layer 4 in the same way. This completes the installation of the Mylar sheet.

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
