Abstract
The utility model relates to an accessory of the communication tools, particularly to a replaceable antenna for mobile phones with a shielding layer anti electromagnetic wave radiations (1), which is mainly used for the shielding of the electromagnetic wave radiations of the mobile phones. The utility model has the advantages of having a simple and practical structure and being able to weaken the radiations of the electromagnetic waves to the human brains, which can not only meet the requirement of the development of the communications industry, but also serves as a good personal protection article for the mobile phone users.
Description
(1) technical field: the utility model relates to the communication tool annex, specifically is meant the replaceable antenna of the mobile phone handsets that are provided with the anti-electromagnetic radiation screen (1).The protection field that belongs to electromagenetic wave radiation.
(2) background technology: mobile phone occupies critical role in daily communication.Number of users increases day by day, and frequency of utilization is frequent day by day, and the operating power of current phone has 2.0W, 0.6W, 0.2W.With 0.6W consumption maximum.Cellie's use habit is to answer device near ear, and antenna is generally apart from head part 2-5cm during conversation, and the suffered radiation density of human body head is at 2.5mw/cm
2About, the Ministry of Public Health is about " the provisional sanitary standard of microwave radiation " the 7th regulation, in radiation density greater than 1mw/cm
2Environmental work the time, must use personal protective equipment.Microwave can be divided into macroscopical thermal effect, microcosmic thermal effect and hot external effect to the injury effect of human body.The microwave that antenna for mobile phone sends is mainly reflected in microcosmic thermal effect and hot external effect to the injury of human body, mobile phone mainly is the equidistant nearer high local organization of water content of antenna of brain, eye to user's injury part, injury has the property of accumulating, gradual, can cause user's psychasthenia, be losing one's memory, mono-anesthesia, symptoms such as graying of hair.The popularizing in the process of mobile phone handsets, bring injury can for more user like this.
The mobile phone radiation protection product that can see on the current market is to have cap sleeve pipe entire area to be provided with to absorb microwave to be the radiation proof device of feature, to say so and only keep off radiation, do not keep off signal on antenna for mobile phone.Mobile phone is a small-sized ambulatory transceiver newspaper radio station, and its emission system is that speech is transformed into electromagnetic wave, goes out with the band transmit of hyperfrequency and microwave by antenna after power amplification.If blocked these radiated waves, signal just sends and has not gone out.And be exactly the electromagnetic wave after power amplification of this frequency range to the human injury.Therefore say and only keep off radiation, not keeping off signal does not have the science reason.
Also having a kind of utility model, is mobile phone handsets microwave protection cover, and its method is to set up non-cap antenna casing on the mobile phone handsets antenna, and non-cap antenna casing and cell-phone cover are connected as a single entity.Be provided with near human body one side at antenna casing and cell-phone cover and return the metal screen layer of penetrating microwave.Be with cell-phone cover when its weak point is to use, and current most of cellie covers mobile phone to hang on the waistband, very inconvenient when therefore using, the antenna casing upper end is easy to generate static in addition, enters dust.
A kind of radiation proof sheet is arranged again, and the specification introduction is to stick on mobile phone to answer the device place.But the electromagnetic wave of answering the device place has changed sound wave into, and to not injury of human body, therefore this radiation proof sheet does not have radiation protection.
(3) summary of the invention: the utility model is the device that a kind of simple, convenient, practical anti-electromagnetic radiation is provided to the cellie.It can weaken the electromagnetic wave radiant intensity of mobile phone emission and swept area and reduce to the Cheng Du very little to the human influence.Can normally send and received signal again.
Design of the present utility model is: the screen that is provided with anti-electromagnetic radiation at the replaceable antenna of all kinds of mobile phone handsets (1) near the inboard of human body.
According to the frequency range and the electromagnetic character of antenna for mobile phone launching electromagnetic wave, select for use insulating material such as plastics that electromagnetic wave can penetrate, plastic cement, rubber as the insulating cell between antenna and the screen.Select wire netting, sheet metal, metal film for use, metal dust coating or mix the metal powder layer that forms with base-material is as the screen of reflection electromagnetic wave.Select for use nano composite material to make and absorb the shielding electromagnetic waves layer.And according to the shielding electromagnetic waves principle, with the reflection electromagnetic wave layer with absorb uses that combines of electromagnetic wave layer, formation composite shielding layer.Set up decorative layer in the external part periphery of replaceable antenna again.

Among the above-mentioned figure 1---replaceable antenna.2---the metal mesh shield layer.3---the sheet metal screen.4---the metal film screen.5---the metal dust screen.6---the nano-complex screen.7---insulating barrier.8---decorative layer
Embodiment 1:
Referring to Fig. 1, Fig. 2, the utility model is set up the plastic cement insulating barrier on the replaceable antenna of mobile phone, establishes the metal mesh shield layer on the semicircle cambered surface outside insulating barrier, forms the replaceable antenna of wire netting.The external part of replaceable antenna is set up decorative layer, and is provided with bearing mark.
The utility model uses the replaceable antenna that screening arrangement is arranged to change the replaceable antenna of unshielded bed device in use, will have the inboard of the close human body of a side subtend of screen to get final product.
