[0002] Mylar sheet, also known as PET polyester film, is a film made by heating dimethyl terephthalate and ethylene glycol with the assistance of relevant catalysts, undergoing ester exchange and vacuum polycondensation, and biaxial stretching. Mylar sheet is an insulating material with the advantages of dimensional stability, flatness and excellent tear strength.

[0003] When installing electronic components, it is necessary to install Mylar sheets with insulating properties on the surface of the electronic components to protect them. There is often a certain distance between electronic components, and traditional electronic components are prone to shaking after being impacted by external forces, causing the electronic components to fall off or collisions between electronic components. Traditional Mylar sheets can only ensure that the electronic components do not conduct electricity to each other, and lack the protective effect on the electronic components.

[0004] Therefore, a new solution needs to be proposed to allow the Mylar sheet to fill the gaps between electronic components to facilitate the reinforcement and protection of the electronic components. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model aims to provide a gap-filling Mylar sheet for electronic components, which can completely fill the gaps between electronic components.

[0008] The utility model is further configured as follows: the distance between the two ends of the thread groove is equal to the length of the second connecting column.

[0009] The utility model is further configured as follows: limiting grooves are provided on the opposite end surfaces of the first and second Mylar sheets, and limiting blocks corresponding to the limiting grooves are fixedly connected to the opposite end surfaces of the first and second connecting columns and the first and second Mylar sheets, and the first and second Mylar sheets are detachably connected to the first and second connecting columns via the limiting blocks and the limiting grooves.

[0010] The utility model is further configured as follows: a friction block coaxial with the first connecting column and in an arc shape is fixedly connected to the end face of the first Mylar sheet facing the first Mylar sheet, a concave-convex surface is fixedly connected to the end face of the friction block facing the first connecting column, an elastic member is provided on the end face of the second Mylar sheet facing the first Mylar sheet, the elastic member always applies pressure to the concave-convex surface of the friction block, and a rubber belt is bonded to the end face of the elastic member facing the friction block.

DETAILED DESCRIPTION

[0016] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] Embodiment: A gap-filled Mylar sheet for electronic components, such as Figure 1 , Figure 2As shown, it includes a first wheat pull sheet 1 and a second wheat pull sheet 2, and the first wheat pull sheet 1 and the second wheat pull sheet 2 have opposite end surfaces that are detachably connected with a first connecting column 3 and a second connecting column 4, respectively. The first wheat pull sheet 1 can adjust the relative distance with the second wheat pull sheet 2 through the first connecting column 3 and the second connecting column 4. The second wheat pull sheet 2 is fixedly connected with a rotating shaft 21 on the end surface facing the first wheat pull sheet 1, and an elastic rope 33 made of rubber with elastic deformation is fixedly connected between the rotating shaft 21 and the first connecting column 3. After the elastic rope 33 is stretched during the rotation of the rotating shaft 21, it is in a taut state, so that the elastic rope 33 has A force is always applied to the first Micron sheet 1 to move away from the second Micron sheet 2. When the electronic component needs to be installed at a position with a specified spacing, the first connecting column 3 and the second connecting column 4 are twisted to reduce the spacing between the first Micron sheet 1 and the second Micron sheet 2 so that the utility model can be placed within the spacing between the electronic components. During the rotation of the first connecting column 3 relative to the second connecting column 4, the elastic rope 33 is stretched by the rotating shaft 21, and then the first connecting column 3 is driven away from the second connecting column 4 under the action of the elastic rope 33, so that the first Micron sheet 1 and the second Micron sheet 2 both press against the side walls of the electronic component, thereby achieving the purpose of filling the spacing between the electronic components.

[0018] like Figure 1 , Figure 2 As shown, a thread strip 31 is fixedly connected to the outer ring surface of the first connecting column 3, and a thread groove 41 corresponding to the thread strip 31 is opened on the inner ring surface of the second connecting column 4 facing the first connecting column 3. The distance between the two ends of the thread groove 41 is equal to the length of the second connecting column 4. This structure facilitates the first connecting column 3 and the second connecting column 4 to be tightly connected or separated from each other. The thread strip 31 and the thread groove 41 are used to achieve adjustable distance between the first connecting column 3 and the second connecting column 4. The force of the elastic rope 33 is greater than the friction between the thread strip 31 and the thread groove 41. When the first connecting column 3 and the second connecting column 4 are connected through the thread strip 31 and the thread groove 41, the elastic rope 33 is always in a stretched state, ensuring that the elastic rope 33 can always drive the first connecting column 3 to rotate along the thread groove 41 so as to keep the first microfilm 1 away from the second microfilm 2, so as to achieve the purpose of filling the gap between the electronic components.

[0019] like Figure 1 , Figure 2As shown, limiting grooves 12 are provided on the opposite end surfaces of the first and second microfilms 1, 2, and the first connecting pillars 3 and the second connecting pillars 4 are respectively fixedly connected with limiting blocks 32 corresponding to the limiting grooves 12 toward the end surfaces of the first and second microfilms 1, 2. The limiting blocks 32 are engaged in the limiting grooves 12 to realize the detachable connection between the first microfilm 1 and the first connecting pillar 3 and the detachable connection between the second microfilm 2 and the second connecting pillar 4. This structural design makes it possible to separately connect the first and second microfilms 1 and 2 corresponding to the size and shape of the electronic components to the first and second connecting pillars 3 and 4, thereby increasing the scope of application of the utility model.

[0020] like Figure 1 , Figure 2 As shown, an arc-shaped friction block 11 coaxial with the first connecting column 3 is fixedly connected to the end face of the first McLa sheet 1 facing the second McLa sheet 2, and an arc-shaped concave-convex surface is fixedly connected to the end face of the friction block 11 facing the first connecting column 3. An elastic member 23 composed of a metal sheet with elastic deformation is provided on the end face of the second McLa sheet 2 facing the first McLa sheet 1. A connecting buckle 22 with a through groove is fixedly connected to the second McLa sheet 2. The elastic member 23 is slidably connected in the through groove of the connecting buckle 22. The end face of the elastic member 23 facing the friction block 11 always presents a convex surface. The elastic member 23 always applies pressure to the concave-convex surface of the friction block 11. A rubber pad is bonded to the end face of the elastic member 23 facing the friction block 11. The rubber pad is used to increase the elastic member 23 and the friction block The friction between the first and second Micro-sheets 1 and 2 is designed to: when the relative distance between the first Micro-sheet 1 and the second Micro-sheet 2 is compressed, the convex surface of the elastic member 23 is abutted against the convex surface of the friction block 11, thereby reducing the friction between the elastic member 23 and the friction block 11, so that after the utility model is placed in the spacing between the electronic components, the force required for the first Micro-sheet 1 to move away from the second Micro-sheet 2 is reduced. When the first Micro-sheet 1 fills the spacing between the electronic components, the convex surface of the elastic member 23 and the concave surface of the friction block 11 naturally rotate and abut against each other under the action of the elastic rope 33, thereby increasing the friction between the elastic member 23 and the friction block 11. At this time, the spacing between the first Micro-sheet 1 and the second Micro-sheet 2 is not easily compressed, thereby increasing the structural stability of the utility model when it is used.

[0021] Working principle: The first and second McLaren sheets 1 and 2 are respectively connected to the first connecting column 3 and the second connecting column 4 through the limiting block 32 and the limiting groove 12. At this time, the first and second McLaren sheets 1 and 2 are twisted along the opening direction of the thread strip 31 and the thread groove 41 to make the first and second McLaren sheets 1 and 2 approach each other. When the first and second McLaren sheets 1 and 2 are smaller than the spacing for placing electronic components, the utility model is placed in the spacing. At this time, the first and second McLaren sheets 1 and 2 are continued to be twisted to make the concave surface of the friction block 11 and the convex surface of the elastic member 23 abut against each other, thereby increasing the contact area between the friction block 11 and the elastic member 23. The elastic member 23 always has a tendency to approach the friction block 11, thereby increasing The friction between the large friction block 11 and the elastic member 23 prevents the electronic components from squeezing the Mylar sheet and changing the spacing between the electronic components when in use, thereby increasing the stability of the utility model when in use. When the utility model is placed in the spacing between the electronic components, the elastic rope 33 is driven by the rotating shaft 21 to be in a stretched state during the rotation of the first connecting column 3 relative to the second connecting column 4. At this time, the elastic force of the elastic rope 33 increases, and the elastic rope 33 in a stretched and taut state always gives a force to the first connecting column 3 so that it has a tendency to rotate relative to the second connecting column 4. This tendency causes the first Mylar sheet 1 to move away from the second Mylar sheet 2, thereby achieving the purpose of completely filling the spacing between the electronic components.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
