Abstract
The invention discloses conductive foam capable of absorbing waves, which comprises a foam body, conductive cloth and an adhesive layer, wherein the foam body is a wave absorbing foam; the conductive cloth is wrapped on the outer surface of the foam body; and the adhesive layer is adhered at the bottom of the conductive cloth. In this way, electromagnetic waves diffused to the surface of the conductive foam can be converted into mature energy or other energy to be eliminated by the conductive foam, so that the security of equipment is improved, electromagnetic threat in environment is weakened, and the shielding effectiveness is improved.
Description
Technical field
The present invention relates to the electromangnetic spectrum field, particularly relate to a kind of waveguide electricity foam of inhaling.
Background technology
Existing foam product mainly is: adopt conductive fabric, common PU foam, PUR sticks on together through mold heated and a fixing shape (like D type, L type, rectangle, semi-circular etc.) behind mould.But this foam has only conductive fabric to play shielding, and the electromagnetic wave major part that acts on the conductive fabric surface is reflected away, and wherein minimum part changes into " 0 " interface of electric current introducing equipment.The PU foam only plays the effect of support, keeps conductive fabric to contact with casing, does not have other functions.
Because existing foam is a reflection electromagnetic wave, do not play the electromagnetic effect of eliminating, so the pollution of environment is not thoroughly eliminated.The electromagnetic wave that high-power components gives off in the electronic equipment also brings threat to sensing unit in the electronic product, and problems such as resonance take place.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of waveguide electricity foam of inhaling; Can its surperficial electromagnetic wave changes into heat energy or other energy eliminate with being diffused into; Improved the fail safe of equipment, weakened the electromagnetism in the environment and threatened, screening effectiveness is improved.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of waveguide electricity foam of inhaling is provided; Comprise: foam body, conductive fabric and glue-line; Said foam body is for inhaling the ripple foam, and said conductive fabric is coated on said this external surface of foam, and said glue-line is attached at the bottom of said conductive fabric.
In preferred embodiment of the present invention, said glue-line is conductive adhesive layer or common layers of two-sided.
The invention has the beneficial effects as follows: the present invention has disclosed a kind of waveguide electricity foam of inhaling; Inhale the ripple foam through adopting; Can its surperficial electromagnetic wave change into heat energy or other energy eliminate with being diffused into, brought safety guarantee promptly for our equipment, weakened the electromagnetism in the environment and threatened; Simultaneously, improved the flexibility and the screening effectiveness of material application, it is greatly convenient also to bring to the designer.
Description of drawings
Fig. 1 is the perspective view that the present invention can inhale one preferred embodiment of waveguide electricity foam;
The mark of each parts is following in the accompanying drawing: 1, foam body, 2, conductive fabric, 3, glue-line.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the embodiment of the invention comprises:
A kind of waveguide electricity foam of inhaling; Comprise: foam body 1, conductive fabric 2 and glue-line 3, said foam body 1 is for inhaling the ripple foam, and this foam is for being transmitted into its surperficial electromagnetic wave; Can convert heat energy to more than 90% or other energy scatter and disappear, reach and absorb electromagnetic purpose.Said conductive fabric 2 is coated on the outer surface of said foam body 1, and said glue-line 3 is attached at the bottom of said conductive fabric 2.
Wherein, said conductive fabric 2 adopts the low-density conductive fabric.Because its superficial density is low, the space is bigger, therefore plays and reduces the effect that its surperficial electromagnetic wave is reflected that is transmitted into.
Said glue-line 3 is conductive adhesive layer or common layers of two-sided.
As the waveguide electricity foam of inhaling of the present invention is installed on the doorframe that cabinet need shield; After the installation, the cabinet door-plate that closes makes door-plate and cabinet doorframe compress (through screw or snap close all around) through external force; When compressing, foam body generation certain elastic deformation makes closely contact between door-plate and the fixed mount; Play the effect of conducting up and down; Cabinet is inside and outside isolates, no matter from the next electromagnetic wave of which direction radiation, as long as touch this foam; The overwhelming majority is converted into other energy by the foam body, and only a few is reflected back by it.Make our equipment work safer.
The present invention has disclosed a kind of waveguide electricity foam of inhaling; The present invention has disclosed a kind of waveguide electricity foam of inhaling; Inhale the ripple foam through adopting; Can its surperficial electromagnetic wave change into heat energy or other energy eliminate with being diffused into, brought safety guarantee promptly for our equipment, weakened the electromagnetism in the environment and threatened; Simultaneously, improved the flexibility and the screening effectiveness of material application, it is greatly convenient also to bring to the designer.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
Claims (2)
1. can inhale waveguide electricity foam for one kind, it is characterized in that, comprise: foam body, conductive fabric and glue-line, said foam body is for inhaling the ripple foam, and said conductive fabric is coated on said this external surface of foam, and said glue-line is attached at the bottom of said conductive fabric.
2. the waveguide electricity foam of inhaling according to claim 1 is characterized in that said glue-line is conductive adhesive layer or common layers of two-sided.
