Abstract
The invention relates to an electromagnetic wave specific absorption rate (SAR) lowering device of a portable terminal, especially relates to an SAR lowering device of a portable terminal, which embeds a metal film or a metal meshwork shape lectromagnetic wave shielding metal member in a housing of the portable terminal, and is capable of reducing the electromagnetic wave specific absorption rate (SAR) in a structure.
Description
Technical field
The present invention relates to portable terminal, is that a kind of electromagnetic wave absorptivity (SAR:Specific Absorption Rate) of portable terminal reduces device concretely.
Background technology
In general, existing member is confined to use EMI (electromagnetic interference (EMI)) coating or conduction adhesive tape etc. on plastic cement, improves wireless sensitivity improving and static improvement etc.On the plastic cement of the structural elements of existing portable terminal device or plastic cement, be coated with EMI (Electronic Magnetic Interference) with coating or adhere to conducting resinl and bring the containment electromagnetic wave absorptivity, but effect is little.
And, also be applied in the form of the outside adhesion metal thing of structural elements, but install very difficultly in narrow space, become the principal element of the assembling throughput rate that reduces product.
Describe with reference to the accompanying drawings, Fig. 1 is the open mode oblique view of portable terminal in the past, and Fig. 2 is the part section oblique view of back shell.As shown in the figure, on the shell 1 of portable terminal, be combined with in the upper end of fuselage cover 2 and renovate shell 3, it can open and close with rotation mode by hinge portion 4, and the LCD (liquid crystal indicator) 5 of display text or numeral is arranged in the installed inside of renovating shell 3.
Simultaneously, on above-mentioned fuselage cover 2, be combined with upper case 2a and lower case 2b,, a plurality of buttons 6 that are used for input information be installed on this upper case 2a so that form certain space portion in inside.
And, for such portable terminal in the past, on plastic material terminal enclosure 1,, be attached with the electromagnetic shielding metal object 10 of metal film or wire netting form such as in the outside of plastic material back shell 2a.
Yet there is the problem that reduces assembling and throughput rate in the assembling electromagnetic shielding with 100 fens loaded down with trivial details difficulties of metal object in the narrow space of such member.
Summary of the invention
Above-mentioned problem in the past and shortcoming propose in order to solve just in the present invention, purpose is to provide a kind of SAR of portable terminal to reduce device, at the inboard metallics that embeds of the shell of portable terminal device, can reduce electromagnetic wave absorptivity (SAR:Specific Absorption Rate) from structure.
For achieving the above object, the SAR of portable terminal of the present invention reduction device embeds the morphosis of the electromagnetic shielding of metal film or wire netting form with metal object by the enclosure at portable terminal.
And described electromagnetic shielding embeds formation with metal object according to the mode that embeds moulding in the fuselage cover of the plastic cement injecting forming material of terminal enclosure and/or the inside of renovating shell.
As mentioned above, the SAR that the present invention relates to portable terminal reduces device, particularly the inside configuration of (front when opening during for lid-turning type terminal) is inserted metallics and is formed in the portable terminal device front, can be effective to improve electromagnetic wave absorptivity (SAR:Specific Absorption Rate) from structure.

Embodiment
With reference to the accompanying drawings, describe embodiments of the invention in detail.
Fig. 3 and Fig. 4 are that the SAR of portable terminal of the present invention reduces device, and Fig. 3 is the part section oblique view of back shell, and Fig. 4 is the partial longitudinal section figure of back shell.
Describe below with reference to Fig. 1, Fig. 3 and Fig. 4, on the shell 1 of portable terminal, be combined with in the upper end of fuselage cover 2 and renovate shell 3, it can open and close with rotation mode by hinge portion 4, and the LCD5 of display text or numeral is arranged in the installed inside of renovating shell 3.
Simultaneously, on above-mentioned fuselage cover 2, be combined with upper case 2a and lower case 2b,, a plurality of buttons 6 that are used for input information be installed on this upper case 2a so that form certain space portion in inside.
And for such portable terminal in the past, in the inside of the terminal enclosure 1 of plastic material, the electromagnetic shielding that is attached with metal film or wire netting form is with metal object 10.
Above-mentioned electromagnetic shielding with metal object 10 according at the fuselage cover 2 of terminal enclosure 1 and/or renovate the form that the inside of shell 3 embeds and carry out combination, as shown in Figures 3 and 4, above-mentioned electromagnetic shielding with metal object 10 with form the plastic cement piece 1 of terminal enclosure 1 ' the form that embeds of pars intermedia fix, form by common embedding moulding manufacturing.
The SAR of aforesaid portable terminal of the present invention reduces the member of device by manufacturing portable terminals such as plastic cement injection mouldings, insert the film of copper or metallics simultaneously in inside or have sheet metal and the formation that netted netting twine is constructed, as a whole, formation wraps the structure of portable terminal with Copper Foil or metal film, can reduce electromagnetic wave absorptivity.
The SAR of above-mentioned illustrated portable terminal reduces device and embeds the film of metallics or have the electromagnetic shielding metal object of netted netting twine structure at the fuselage cover of the plastic material of portable terminal and the inboard of renovating shell, formation wraps the structure of portable terminal with metal object with electromagnetic shielding, can reduce electromagnetic wave absorptivity thereby have, improve the advantage of the assembling throughput rate of product.
Above embodiment only limits to illustrate the present invention, but not is used to limit the present invention.
