Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic shielding bags, in particular to an impact-resistant electrostatic shielding bag. Background Art

[0002] Static shielding bags, also known as anti-static bags, are packaging bags made of anti-static materials. This type of bag is not prone to static electricity and can shield external static electricity. Static shielding bags are usually made of shielding materials and anti-static materials. The inner layer of anti-static material prevents static electricity from being generated inside the bag, and the outer layer is provided with shielding material to form a Faraday cage, forming an "induction hood" effect, which can effectively isolate items from external electrostatic fields, thereby protecting the items in the bag from static electricity hazards and preventing electromagnetic interference. It is often used to package and protect electrostatically sensitive components such as PCBs, LEDs, chips, and various integrated circuits. Many electronic products such as hard drives, switches, routers, graphics cards, and memory sticks also require the protection of static shielding bags.

[0003] It is precisely because electrostatic shielding bags are often used to hold various components and electronic products, many of which are relatively fragile. If the electrostatic shielding bags containing these items are accidentally dropped and subjected to external impacts, the internal items can be easily damaged. In addition, most components and electronic products have sharp and thin convex edges and corner structures. If there is a large external impact and the corner structure of the internal items interacts, the electrostatic shielding bags will also be damaged. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the utility model shown in the accompanying drawings and described according to the accompanying drawings are merely exemplary, and the utility model is not limited to these embodiments.

[0026] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not very relevant are omitted.

[0027] Reference Figure 1 and Figure 2 As shown, an embodiment of the utility model provides an impact-resistant electrostatic shielding bag, and the impact-resistant electrostatic shielding bag includes a bag surface 1 and a bag bottom 2.

[0028] Combination Figure 1 and Figure 3 As shown, the bag surface 1 includes an antistatic layer 11, a shielding layer 12 and a buffer layer 13 which are stacked in sequence. The buffer layer 13 includes an air column portion and a bubble array portion, wherein the air column portion includes a plurality of air columns 131 arranged side by side, and the bubble array portion includes a plurality of buffer bubbles 132 arranged in an array, wherein each of the air columns 131 and a single row of buffer bubbles 132 are alternately arranged, so that the air column portion and the bubble array portion are interlaced, and the extension height of the air column 131 on the bottom surface of the buffer layer 13 is greater than the extension height of the buffer bubbles 132 on the bottom surface of the buffer layer 13.

[0029] Combination Figure 2and Figure 4 As shown, the bag bottom 2 includes multiple sections of composite material plates 21 connected end to end, and the composite material plates include the antistatic layer 11, the shielding layer 12 and the elastic material layer 211 stacked in sequence, and the multiple composite material plates 21 can be folded and gathered.

[0030] The impact-resistant electrostatic shielding bag provided by the embodiment of the utility model has a composite buffer layer 13 on the material layer of the bag surface 1. The air column part and the bubble array part included in the buffer layer 13 can buffer the impact force contacting the bag surface. Figure 3 As shown, since the air column 131 and the buffer bubble 132 are at different heights, even if the air column 131 on the outside is damaged after being impacted, the buffer bubble 132 at the lower position is not easily damaged together, and can be used as a backup buffer structure to achieve a secondary buffer effect; the air column part and the bubble array part are interlaced with each other, and can evenly cover the vulnerable area of ​​the entire bag surface 1 to disperse the external impact, and any air column 131 is equipped with a buffer bubble 132 that can be used as a backup buffer structure. The structure of the improved bag bottom 2 of the electrostatic shielding bag is a plurality of composite material plates 21, and the plurality of composite material plates 21 can be folded and gathered, so that when the electrostatic shielding bag is impacted by the outside, the plurality of composite material plates 21 are folded, which can play a spring-like buffering role, and when the elastic material layer 211 of the composite material plate 21 is folded into one body, the strength of the bag bottom 2 is also greater. Therefore, through the cooperation of the bag surface 1 and the bag bottom 2, the electrostatic shielding bag can effectively resist external impacts and protect the items placed inside, especially for various components and electronic products, to prevent damage to the items and avoid the electrostatic shielding bag from being easily punctured.

[0031] The material of the shielding layer 12 covering the periphery of the article is the main part of the electrostatic shielding, and its conductive performance is very important. Generally, the shielding layer 12 includes an aluminum coating. In some embodiments, in order to further improve the conductive performance, conductive additives such as conductive fibers or conductive particles can be added to the external material. These additives can increase the conductive performance and improve the electrostatic shielding effect. At the same time, the shielding layer 12 can also adopt a multi-layer composite structure, in which each layer can have different conductive properties to achieve more efficient electrostatic shielding.

[0032] The antistatic layer 11 is an inner layer in the electrostatic shielding bag that is in direct contact with the items placed therein, and the antistatic layer 11 includes a polyethylene material layer 111 and a polypropylene material layer 112. The polyethylene material layer 111 and the polypropylene material layer 112 can greatly increase the surface resistance of the antistatic layer 11, prevent the generation of static electricity, eliminate static electricity, and better protect electrically sensitive components from potential electrostatic hazards. Moreover, the polyethylene material layer 111 and the polypropylene material layer 112 have good toughness and wear resistance, further protecting the internal items from friction and scratches.

[0033] The buffer layer 13 is a key part of the electrostatic shielding bag. The air column 131 and the buffer bubble 132 are closed structures and are not easy to break. The size and density of the air column 131 and the buffer bubble 132 can be adjusted as needed to meet the needs of different items and impact strength. In order to further enhance the impact protection effect, a shock-absorbing material with good energy absorption and dispersion capabilities can be introduced into the buffer layer 13 to further absorb and disperse the damage to the internal items caused by the impact. In this embodiment, the buffer layer 13 is filled with a polyurethane material filler outside the air column part and the bubble array part, while maintaining an overall light weight and good compressibility.

[0034] As another implementation of the buffer layer 13, the air column part and the bubble array part can be arranged in layers, and the air column part is stacked on the upper layer of the bubble array part, which can also achieve the above-mentioned impact resistance effect.

[0035] On this basis, an anti-permeation layer 14 is further arranged between the buffer layer 13 and the shielding layer 12, and the anti-permeation layer 14 comprises a polyester material layer. The polyester material has high tensile strength and wear resistance, and also has good waterproof performance.

[0036] In this embodiment, the elastic material layer 211 may be made of rubber or elastic resin material.

[0037] Furthermore, two parallel concave-convex self-sealing strips 16 are arranged on the top of the bag surface 1. The continuous parallel concave-convex self-sealing strips 16 can more effectively ensure the airtightness of the electrostatic shielding bag after sealing, and even if one of the concave-convex self-sealing strips 16 is not sealed well, the other concave-convex self-sealing strip 16 can also provide protection as a backup airtight structure.

[0038] Since the air column portion and the bubble array portion need to be spread over the corresponding storage area of ​​the bag surface 1 for placing items, when the user holds the electrostatic shielding bag, he can grab the side seal edge next to the storage area of ​​the bag surface 1. In order to make the user hold the above-mentioned impact-resistant electrostatic shielding bag more stably, the bag surface 1 is provided with a rough texture area 15 on the side seal edges away from the air column portion and the bubble array portion.

[0039] A hanging hole 10 is provided at the top of the bag surface 1, and a conductive metal ring connected to the shielding layer 12 is provided in the hanging hole 10. With this arrangement, the generated charge can be conducted to the place where the hanging hole 10 is hung through the conductive metal ring, and the conductive metal ring provides a high-strength hanging structure, so that the static shielding bag is not likely to be torn when heavy items are placed in the hanging hole 10.

[0040] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0041] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
