Description
Affiliated technical field:
The utility model relates to the electromagnetic compatibility technology field, especially a kind of back listening type mobile phone protective shield of radiation shielding apparatus.
Background technology:
The mobile phone hand-held set is called for short mobile phone, the comprehensive launching electromagnetic wave of meeting when conversation, excessive or the long electromagnetic radiation meeting of mistake influences user's health, the mobile phone of commonly using is all to be arranged at the inboard that mobile phone relies on human body with answering device, display, keyboard, transmitter, when the user in when conversation, the device hole of answering of inner casing must be abutted in the ear position so that two-way call, in this i.e. head, brain position by antenna and inner casing radiation user constantly of electromagnetic wave simultaneously, and then work the mischief for user's health.
Have at present that to use the patch earphone be to lower electromagnetic radiation to one of effective ways of user's brains injury, but the patch earphone carries and uses relatively inconvenience; Also useful radiation proof paster is attached to answers device hole place, with this electromagnetic radiation shielding, is not electromagnetic wave emission source but answer place, device hole, and the area shield ranges of this paster is insignificant really, does not have the effect that the protection user is not subjected to the electromagnetic radiation injury; What is more is with the so-called electromagnetic wave film that absorbs, specification is introduced, be to stick in the outer cage of mobile phone, but absorbing the electromagnetic wave film can only consume the electro-magnetic wave absorption that is radiated on the film, and the electromagnetic wave of directive human body oppositely can not be absorbed the outside of mobile phone; If this film truly can oppositely be drawn onto electromagnetic wave on the film, the signal of mobile phone also just sends and has not gone out, and therefore can conclude that this film is invalid.
Summary of the invention:
Carry inconvenience or the good or not absolutely void shortcoming and defect of shield effectiveness in order to overcome above-mentioned mobile phone anti-electromagnetic radiation product, the utility model provides a kind of mobile phone anti-electromagnetic radiation screening arrangement, the outer cage of this screening arrangement and mobile phone and/or on, down turnover cover, on, following slip lid combines, answer the device hole and be arranged on the back side of display screen and/or function key, have the bluff piece of electromagnetic wave shielding concurrently in the inside attaching one of answering the device hole, the outside of antenna is arranged on mobile phone when answering state electromagnetic wave shielding, easy to carry, shielding surface is big, screen is tight, and effectively electromagnetic radiation shielding can normally send and received signal again user's injury.
The purpose of this utility model is to realize like this, outer cage and/or upper and lower renovating with electromagnetic wave shielding and mobile phone, upper and lower slip lid combines, antenna is arranged between the inside and outside casing, or antenna is arranged on the upturning lid of setting up electromagnetic wave shielding, or down turnover cover or last slip lid, or the following outside of slip lid when answering state; Answer the device hole and be arranged on the outer cage outer upper end or be arranged on display screen and/or the back side of function key, have the bluff piece of electromagnetic wave shielding in the inside attaching one of answering the device hole concurrently; Between antenna and the electromagnetic wave shielding dielectric isolation layer is set; Antenna is electrically connected with the power amplifier feeder line through contact or socket; When the comprehensive electromagnetic signals of antenna, the electromagnetic wave of directive human body is run into screening arrangement and is reflected to absorb away from the direction of human body or by electromagnetic wave shielding and consumes, reach the user and not injured by electromagnetic radiation, do not influence the purpose of speech quality again.
The outer cage of described electromagnetic wave shielding and mobile phone combines, and is meant that outer cage is the powder of being manufactured or mixed in a ratio ginseng shielding material by electromagnetic shielding material in manufacturing the raw material of housing, the outer cage that injection mo(u)lding is made in mould again; Can also be inner surface and/or the outer surface that shielding material is combined in outer cage by methods such as vacuum coating, stickup, coating, vapour deposition, hot pressing.Upturning lid, down turnover cover, last slip lid, following slip lid set up the implementation method of electromagnetic wave shielding and said method with.
Described electromagnetic wave shielding can be lamina reticularis, platy layer, paper tinsel shape layer, membranaceous layer, powder coated layer, and the surface of electromagnetic wave shielding can be made into curved surface shaped, corrugated face shape, fold plane shape, planar shaped.
Described antenna can be the antenna for mobile phone of different shapes such as linear, whip shape, sheet shape, erietiform, clavate.
Described electromagnetic wave shielding comprises the reflection electromagnetic wave screen, absorbs electromagnetic wave shielding, composite electromagnetic screen, and the material that constitutes the reflection electromagnetic wave screen has metallic conduction material and conducting polymer composite; Constituting the material that absorbs electromagnetic wave shielding has: 1, ferrite; 2, polycrystalline iron fiber series; 3, pottery series is mainly thyrite; 4, conducting polymer series mainly contains the p-phenylenediamine (PPD) schiff bases and the aliphat ethylenediamine schiff bases of aromatic amine; 5, metal fine powder series; 6, nano material etc.The composite electromagnetic screen is to be composited with absorbing electromagnetic wave shielding by the reflection electromagnetic wave screen, and it absorbs electromagnetic wave shielding and is arranged on a side that relies on antenna for mobile phone, and the reflection electromagnetic wave screen is arranged on a side that relies on user's human body.
When electromagnetic wave shielding during, apply a dielectric isolation layer at the contact position corresponding to the contact position of the exposed circuit of mobile phone body and charging circuit and antenna exposed part.
The beneficial effects of the utility model are, the mobile phone shielding device is tight, and shielding surface is big, and shielding electromagnetic wave is to user's injury effectively; Electromagnetic wave shielding and casing or renovate or slip lid combines, simple in structure, easy to carry.
