Card bag with signal shielding function

Abstract

The invention relates to the technical field of card bags and in particular to a card bag with a signal shielding function. The card bag comprises a card bag body. The card bag body comprises openablefront clip and back clip. The top of the back clip is provided with a separating layer. The separating layer partially extends to the front clip, and a card pocket is formed by the separating layer and the card bag body. An opening of the card pocket is positioned in an area of the front clip. Signal shielding layers are respectively embedded in the separating layer and the card bag body. According to the card bag provided by the invention, by using a first signal shielding layer and a second signal shielding layer to coat a mobile communication device in a structure of the card pocket, signal isolation can be performed on the mobile communication device, signal connection of the mobile communication device with the outside can be cut off, so as to realize signal shielding; in addition, because the separating layer partially extends to the front clip, while the card bag is folded, the extending part of the separating layer is cooperated with the front clip, so as to realize natural sealing of the card pocket in a folding process, improve leakproofness of the card pocket, and reinforce the single shielding effect of the card pocket.

Description

technical field [0001] The invention relates to the field of card case technology, in particular to a card case with a signal shielding function. Background technique [0002] At present, the development of mobile communication technology is changing with each passing day, and it plays an important role in people's production and life. However, while mobile communication technology brings great convenience to people, it also generates some problems that cannot be ignored. For example, (1) the mobile terminal becomes a new source of noise pollution, which interferes with the normal work order; (2) becomes a new leaking channel, which poses a threat to information security; (3) becomes a new unsafe factor, which brings hidden dangers to enterprise security (4) become a new means of crime and bring harm to social stability. Therefore, in some specific cases, it is necessary to adopt technical means to shield or limit the communication signal to avoid the harm caused by the lo...

Problems solved by technology

So many cards are not easy to store, prone to confusion, and often bring a lot of unnecessary troubles, card packs appear just to manage so many cards

In the existing card case, it is mainly to manage various cards more conveniently and quickly, such as a kind of integrated card case for mobile phone disclosed by patent publication number CN208015795U, which includes a mobile phone back cover and a supporting compartment. The back side of the support compartment is provided with a plastic hard film, and the plastic hard film includes rectangular adhesive strips on both sides and a rectangular plastic strip in the middle, and an adhesive is provided on the back of the plastic strip and adhesive strip Adhesive with the supporting compartment, the front of the plastic strip is a smooth surface, and the front of the adhesive tape is provided with an adhesive to adhere to the inner side of the back cover of the mobile phone. The card holder can be used to store cards or certificates The accessories are convenient to use in combination to achieve multiple functions, but the card holder cannot realize the signal shielding function, so its application is limited
