Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has an effect of effectively preventing the emission of electromagnetic waves generated by a mobile phone to the surroundings without impairing the function of the mobile phone as a telephone, and an antibacterial effect and an anti-slip effect. The present invention also relates to a mobile phone cover.

[0002]

2. Description of the Related Art Due to recent advances in electronics technology,
Electronic devices, home appliances, and personal wireless devices are all around us. Electromagnetic waves are emitted from these electronic devices, and although these electromagnetic waves are useful, it has been pointed out that they may adversely affect the human body.

In particular, it is known that a mobile phone also emits a lot of electromagnetic waves at the time of reception / transmission. In particular, due to the usage pattern of the mobile phone, the mobile phone is used in a state of being close to the head during a call. The emitted electromagnetic wave directly hits the head of a person, and the mobile phone user is affected by the electromagnetic wave in the most dangerous form. Conventionally, in order to prevent such a danger, it is known to use an electromagnetic wave protection mobile phone cover made of an electromagnetic wave shield material in order to shield the emission of electromagnetic waves without disturbing the transmission / reception function of the mobile phone.

[0004]

However, the above-mentioned conventional electromagnetic wave protection mobile phone cover is focused on the electromagnetic wave shielding function and lacks convenience in use. That is, it is not easy to integrate the mobile phone and the electromagnetic wave protection mobile phone cover by wrapping up the compact body while maintaining the configuration and shape that does not interfere with the transmission and reception of the mobile phone. It caused a sense of incongruity and gave an unstable feeling. Furthermore, there were many accidents where the product accidentally slipped out of the stored pocket or bag and was damaged by a drop impact.

[0005]

According to the present invention, in order to solve the above problems, in a cover of a mobile phone, a cover body includes an upper half cover body and a lower half cover for covering an upper half part and a lower half part of the mobile phone. It is composed of a half cover body, and each cover body is connected in a stretchable manner. Each cover body is made of a material having an electromagnetic wave shielding function, and the outer surface of the cover body is processed to prevent slippage. It is intended to provide a mobile phone cover.

Another feature is that the material has an antibacterial function.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, a mobile phone cover is constituted by an upper half cover body and a lower half cover body that cover the upper half portion and the lower half portion of the mobile phone, and the cover bodies are connected in an extendable and contractible manner. Set up
I tried to fit the cell phone exactly to the cell phone body no matter what the condition. Therefore, especially in the case of flip-type mobile phones, when the mobile phone is closed, the expandable part expands sufficiently to hold the mobile phone body firmly with appropriate tension, and when opening or closing the mobile phone body. According to the opening / closing angle of the upper and lower halves, the expandable / contractible portion sequentially expands and contracts to maintain an integrated state without creating an extra gap between the mobile phone main body and the mobile phone cover.

Further, the mobile phone cover body is made of a material having a function of shielding electromagnetic waves, and shields electromagnetic waves emitted from the mobile phone to ensure the safety of the user. That is, the electromagnetic wave emitted from this mobile phone is an ultra-high frequency wave called microwave and its strength is 100
~ 200 milligauss and the body itself are small, but the power of the electromagnetic waves emitted is strong, so shield the periphery of the mobile phone with a partition of a metal conductor and let the metal conductor as a partition absorb the electromagnetic waves generated from the mobile phone. The electromagnetic wave is shielded by keeping it out.

In order to actually shield an electromagnetic wave by covering the cell phone with the cell phone cover, an electromagnetic wave shielding material is used as a material itself constituting the cell phone cover.

This electromagnetic wave shielding material is manufactured by applying electromagnetic shielding to a base material such as a cloth, a woven fabric, a resin, a rubber, a non-woven fabric or the like, which has conventionally been a product, to make it conductive.

As a general type method of this electromagnetic shield, there are used a composite material, a metal mesh, a metal material, which is a composite material mixed with a surface treatment such as a conductive paint, electroless plating, vapor deposition or the like, or metal powder. There is metal bonding using foil tape.

The metal used for the electromagnetic shield is
There are silver, titanium dioxide, nickel, copper, aluminum, etc.

On the outer surface of the mobile phone cover body, there is an anti-slip effect by using a foam resin sheet obtained by coating a mesh core material such as polyester thread with foam resin in a mesh shape. In addition to the large number of irregularities formed on the surface of this foamed resin sheet, the foamed resin, which is the raw material, is highly elastic and has a large coefficient of friction. Yes Very easy to use. When such a foamed resin sheet is used for the part of the mobile phone cover that is often touched when using the mobile phone, the operation error of accidentally dropping the mobile phone is eliminated, and it is also used for the contact part with the main body of the mobile phone. As a result, the integration of the mobile phone body and the mobile phone cover is strengthened to make the open / close operation and button operation of the mobile phone body comfortable and improve usability. In particular, mobile phones are always carried for the purpose of use, and when using them, they can be taken at any time and place. For example, when walking, they may have to be taken out immediately from the bag or pocket. In such a case, handling becomes particularly easy.

Further, all the materials used for the cover of the mobile phone are antibacterial processed by adding an inorganic antibacterial agent or by applying it on the surface, which matches the cleanliness of modern people. It has the effect of giving hygiene and comfort to use.
