Description
Technical field:
The utility model relates to conduction and technical field of electromagnetic shielding, specifically refers to a kind of novel damping screening conductive cloth.
Background technology:
Electronic electric equipment digitlization increasingly, Highgrade integration, signal level small quantization, to meet the requirement of its high speed, lightweight and miniaturization, so electronic devices and components are very easily subject to outside electromagnetic interference and produce misoperation, have serious consequences; Electromagnetic wave also can cause damage to human body in addition.Therefore in the design of electronic electric equipment, except correct design circuit and rational deployment electronic component, adopting electromagnetic shielding material is eliminate and weaken electromagnetic interference and electronic devices and components are played to the choose reasonable of damping, at present on wiring board winding displacement and pcb board.Conventional electromagnetic shielding material is conducting foam.
At present, existing conducting foam is generally that cloth is electroplated and formed metallized fabrics, removing to wrap up common foam formation conducting foam with conductive fabric, but, because foam itself is non-conductive, there is no shield effectiveness, play the conductive fabric that only has coated outside of shielding action, screening effectiveness reduces greatly, due to the restriction conducting foam of production technology, general thickness being good at below 0.5mm millimeter produced, and along with the trend of miniaturization of electronic products, ultrathin, thickness requirement to shielding material is more and more thinner, and existing shielding material cannot meet the demands.
Utility model content:
The purpose of this utility model is for the deficiencies in the prior art, and a kind of novel damping screening conductive cloth is provided, this conductive fabric quality softness, and impedance is low, ground connection excellent performance, shielding properties are high, has the effect of damping, buffering simultaneously; The conductive fabric being made is like this easy to cross cutting processing and assembling, is applicable in the consumer electronics product such as mobile phone, panel computer for damping and electromagnetic shielding.
For achieving the above object, the utility model adopts following technical scheme, a kind of novel damping screening conductive cloth, it comprises spongy layer, hot melt adhesive layer, grenadine layer, intermediate metal, the coat of metal, metal protection layer, spongy layer is bonded together by hot melt adhesive layer and grenadine layer, the outside of grenadine layer is provided with intermediate metal, the coat of metal, metal protection layer successively, and the lower end of spongy layer is provided with intermediate metal, the coat of metal, metal protection layer successively.
Described grenadine layer thickness is 0.08mm-0.12mm, and sponge thickness is 1mm-3mm.
The utility model beneficial effect is: spongy layer is bonded together by hot melt adhesive layer and grenadine layer, the outside of grenadine layer is provided with intermediate metal, the coat of metal, metal protection layer successively, the lower end of spongy layer is provided with intermediate metal, the coat of metal, metal protection layer successively, this conductive fabric quality softness, impedance is low, ground connection excellent performance, shielding properties are high, has the effect of damping, buffering simultaneously; The conductive fabric being made is like this easy to cross cutting processing and assembling, is applicable in the consumer electronics product such as mobile phone, panel computer for damping and electromagnetic shielding.
Brief description of the drawings:
Fig. 1 is sectional view of the present utility model.
Embodiment:
As shown in Figure 1, the utility model comprises spongy layer 1, hot melt adhesive layer 2, grenadine layer 3, intermediate metal 4, the coat of metal 5, metal protection layer 6, spongy layer 1 is bonded together by hot melt adhesive layer 2 and grenadine layer 3, the outside of grenadine layer 3 is provided with intermediate metal 4, the coat of metal 5, metal protection layer 6 successively, and the lower end of spongy layer 1 is provided with intermediate metal 4, the coat of metal 5, metal protection layer 6 successively.
Described grenadine layer 3 thickness are 0.08mm-0.12mm, and sponge thickness is 1mm-3mm.
The utility model conductive fabric quality softness, impedance is low, ground connection excellent performance, shielding properties are high, has the effect of damping, buffering simultaneously; The conductive fabric being made is like this easy to cross cutting processing and assembling, is applicable in the consumer electronics product such as mobile phone, panel computer for damping and electromagnetic shielding.
The above is only preferred embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
