[0020] The present invention will be described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the scope of protection of the present invention more clearly defined.

[0021] A brief overview of one or more aspects is given below to provide a basic understanding of these aspects. This overview is not an exhaustive survey of all contemplated aspects, and is neither intended to identify key or decisive elements of all aspects nor to define the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that follows.

[0022] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0023] As Figures 1-3 shown, a stable wiring rack with electromagnetic shielding function includes a bottom release film 1 and a wiring support structure 2 disposed thereon. The wiring support structure 2 includes a glue avoidance part 3 and a glue sticking part 4. The glue avoidance part 3 has a T-shaped structure. The side of the glue avoidance part 3 facing the bottom release film 1 has adhesiveness, so that the T-shaped glue avoidance part 3 is adhered to the bottom release film 1. A transparent protective film is disposed on the side of the glue avoidance part 3 facing away from the bottom release film 1. The transparent protective film can cover the glue avoidance part 3. The thickness of the transparent protective film is 25 - 250 μm. One side edge of the glue avoidance part 3 is aligned with one long side edge of the bottom release film 1. There is enough space between the other side edge of the glue avoidance part 3 opposite thereto and the other long side edge of the bottom release film 1. Glue is applied in this space to form a glue sticking part 4 with a bonding function, and several wiring racks 5 are adhesively bonded at intervals in this space. That is, there is a gap between two adjacent wiring racks 5, thereby realizing the segmented arrangement of the wiring racks 5, facilitating the segmented operation during subsequent mounting, and improving the accuracy of mounting. One end of the wiring rack 5 is adhered to the glue sticking part 4, and the opposite end extends out of the bottom release film 1 and is suspended. A cable 6 is passed through the wiring rack 5 in total. A buffer foam is attached to the inner side of the bent part of the wiring rack 5, which can reduce the deformation of the cable 6 passing through the wiring rack 5 after collision and improve the overall stability.

[0024] A plurality of through holes 7 are provided on the side of the glue avoiding portion 3 away from the adhesive portion 4. The shape of the through holes 7 is one of circular and elliptical shapes or a combination of the two. The shapes, sizes, etc. of all the through holes 7 on the glue avoiding portion 3 can be completely the same, partially the same, or completely different, and can be flexibly adjusted according to actual needs to improve application flexibility and practicality. A plurality of first semicircular holes 8 are provided on the other side opposite to the glue avoiding portion 3 (that is, the side close to the adhesive portion 4), and a plurality of second semicircular holes 9 are provided on the side of the adhesive portion 4 close to the glue avoiding portion 3. A second semicircular hole 9 is arranged between two adjacent wiring racks 5. The number of the first semicircular holes 8 and the second semicircular holes 9 is the same and they are adapted to each other. Each first semicircular hole 8 is connected to a second semicircular hole 9 to form a full circle, which is convenient for mounting and positioning and improves positioning accuracy. The shapes, sizes, etc. of the wiring racks 5 at the adhesive portion 4 can be completely the same, partially the same, or completely different, and can be flexibly adjusted according to actual needs to improve application flexibility and practicality.

[0025] The size of the bottom release film 1 is larger than that of the wiring support structure 2, and the wiring support structure 2 cannot completely cover the bottom release film 1. The bottom release film 1 can be provided with a number of positioning holes as required, which is convenient for positioning during later assembly. The bottom release film 1 can also be provided with a knife as required, which is convenient for segmented operation during subsequent mounting and improves mounting accuracy.

[0026] A conductive double-sided adhesive is arranged in the space between the other side of the adhesive avoidance portion 3 and the other long side of the bottom release film 1 to form an adhesive portion 4, which has good bonding performance, a resistance value of less than 0.1 ohm, and a 180° peeling force greater than 8N / 25mm.

[0027] The wiring rack 5 is made of ultra-thin conductive cloth with a resistance value of less than 0.1 ohms. The thickness of the adhesive portion 4 is no more than 0.05 mm. The thinning helps to reduce costs and body weight, and is more convenient for the aesthetic design of the entire machine appearance.

[0028] The conductive cloth is bent into a hollow shielding structure, which is supported by multiple ABS solid rods to prevent the structure from collapsing, thereby forming a wiring rack 5, which allows the cable 6 to pass through the inside of the wiring rack 5, facilitating wiring and providing better electromagnetic shielding function for the cable 6.

[0029] Compressive strength test of cushioning foam: 50% compression, pressure 145-225KPa.

[0030] In the present invention, a plurality of wiring racks 5 arranged in sections and at intervals are connected into a whole through the bottom release film 1, so that the mounting process that originally required multiple times is integrated into one time, which significantly improves the work efficiency.

[0031] Example 1

[0032] As shown Figures 1-3 in the figure, a stable wiring rack with electromagnetic shielding function includes a bottom release film 1 and a wiring support structure 2 arranged thereon. The size of the bottom release film 1 is larger than that of the wiring support structure 2. The length of the bottom release film 1 is 302 mm and the width is 20 mm. The bottom release film 1 is symmetrically formed by splicing two completely identical release films. The wiring support structure 2 cannot completely cover the bottom release film 1. The wiring support structure 2 includes a glue avoidance part 3 and an adhesive part 4. The glue avoidance part 3 is in a T-shaped structure. The side of the glue avoidance part 3 facing the bottom release film 1 has adhesiveness, so that the T-shaped glue avoidance part 3 is adhered to the bottom release film 1. A transparent protective film is arranged on the side of the glue avoidance part 3 facing away from the bottom release film 1, and the transparent protective film can completely cover the glue avoidance part 3. One side edge of the glue avoidance part 3 is aligned with one long side edge of the bottom release film 1, and there is enough space between the other side edge of the glue avoidance part 3 opposite to it and the other long side edge of the bottom release film 1. Glue is applied in this space to form the adhesive part 4, and then three wiring racks 5 are adhesively bonded at intervals in this space, that is, there is a gap between two adjacent wiring racks 5, so as to realize the segmented arrangement of the wiring racks 5, facilitate the segmented operation during subsequent mounting, and improve the accuracy of mounting. One end of the wiring rack 5 is adhered to the adhesive part 4, and the opposite end extends out of the bottom release film 1 and is suspended. The shapes and sizes of the two wiring racks 5 on both sides are completely the same. The length of the wiring rack 5 in the middle position is different from that of the wiring racks 5 on its two sides and is the smallest. A cable 6 is passed through the wiring rack 5 in total. A buffer foam is attached to the inner side of the bend of the wiring rack 5 through SDK8101P double-sided adhesive, which can reduce the deformation of the cable 6 passing through the wiring rack 5 after collision and improve the overall stability.

[0033] Four through holes 7 are opened on the side of the glue avoidance part 3 away from the adhesive part 4. Among them, the through hole 7 on the rightmost side of the glue avoidance part 3 is circular, and the remaining three through holes 7 are all elliptical. Two first semi-circular holes 8 are opened on the other side of the glue avoidance part 3 (that is, the side close to the adhesive part 4). Two second semi-circular holes 9 are opened on the side of the adhesive part 4 close to the glue avoidance part 3. One second semi-circular hole 9 is arranged between two adjacent wiring racks 5. The first semi-circular holes 8 and the second semi-circular holes 9 are in one-to-one adaptation. Each first semi-circular hole 8 is docked with a second semi-circular hole 9 to form a complete circle, which is convenient for mounting positioning and improves the positioning accuracy.

[0034] The model of the bottom release film 1 is 75T055B, the thickness is 75 μm, and the color is blue. A number of positioning holes can be reserved on the bottom release film 1 according to actual needs, which is convenient for positioning during later assembly. A cutting knife can also be reserved on the bottom release film 1 according to actual needs, which is convenient for the segmented operation during subsequent mounting and improves the accuracy of mounting.

[0035] The transparent protective film is made of a transparent polyester film for electrical insulation 6020, which has good dielectric properties and high physical and mechanical properties, and has a thickness of 50 μm.

[0036] The glue avoidance part 3 is made of Mylar tape. In the space between the other long side of the glue avoidance part 3 and the other long side of the bottom release film 1, a conductive double-sided tape of model 3M9425HT is arranged to form an adhesive part 4, which has good bonding performance, a resistance value less than 0.1 ohm, and a 180° peel strength greater than 8 N / 25 mm.

[0037] The wiring rack 5 is a hollow shielding structure bent from a conductive cloth with a thickness of 0.05 mm. The resistance value of the conductive cloth is less than 0.1 ohm. The hollow shielding structure is supported by multiple ABS solid rods to prevent the structure from collapsing, thereby forming the wiring rack 5. Then, the cable 6 can pass through the inside of the wiring rack 5, providing an electromagnetic shielding function for the cable 6. The thickness of the adhesive part 4 is 0.045 mm. Since there are three wiring racks 5 arranged, the adhesive part 4 between two adjacent wiring racks 5 has a rounded corner adapted to the wiring rack 5, which thins the thickness of the adhesive part 4 and the wiring rack 5, helps to reduce costs and the weight of the fuselage, and is more conducive to the aesthetic design of the overall machine appearance.

[0038] Compressive strength test of the buffer foam: 50% compression, pressure 145 - 225 KPa.

[0039] The SDK8101P double-sided tape is an ultra-thin PET double-sided tape with a thickness of 10 - 14 μm. It has strong adhesion and temperature and weather resistance, and has a good bonding and fixing effect on the adherend. The adhesion force tested according to ASTM D3330 is greater than 800 gf / inch, and it also has excellent die-cutting processing performance.

[0040] In this embodiment, the three segmented and spaced wiring racks 5 are connected into a whole through the bottom release film 1, integrating the originally required multiple mounting processes into one, significantly improving the working efficiency.

[0041] For the parts or structures not specifically described in the present invention, existing technologies or existing products can be adopted, and no further elaboration will be made here.

[0042] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
