Most of electromagnetic wave can be reflected back by conductive shield adhesive tape, so as to prevent the extraneous various electricity including radio wave signal
Magnetic wave impacts high frequency signal transmission.But existing conductive shield adhesive tape is directly exposed due to the conductive base layer on surface
Outside, be easily subject to some unnecessary disturbance of electronic signal in use, but also can because conductive base layer it is directly exposed
Cause the conducting direction of conductive shield adhesive tape mixed and disorderly outside, cause its electric conductivity unstable, so as to cause shielding electromagnetic signal
Hydraulic performance decline and work to electronic equipment impacts；And easily aoxidized in use by air ambient, cause service life
Greatly shorten.Furthermore the conductive base layer thickness of existing conductive shield adhesive tape is larger, and wherein conductive base layer is using plastic-aluminum
Membrane structure, since aluminum plastic film and base layer are of a relatively high with reference to rear thickness, it does not have good bending performance, and flexibility is not
It is good, it is not easy to be fabricated to the shape of needs, constrains use of the existing conductive tape in consumption electronic product, applies such as electric
Sub- facility switching power supply transformer, it is not necessary to during big curvature component can also normal use be wrapped in the outside of electronic unit,
The effectiveness reached, still, in electronic equipment in widely used FFC components (for example the FFC of electronic equipment is flexible
Flat cable), due to needing big curvature to the parcel of FFC components, so being carried out using existing conductive shield adhesive tape
During parcel, it be easy to cause the fragmentation of aluminum plastic film, fracture, so that the effect that the component electromagnetic shielding to electronic equipment has not had；
More also it is that existing conductive shield adhesive tape is since using aluminum plastic film, as conductive base layer, it is thick after being combined with base layer
Degree is high, applies when installing the compact electronic equipment of electronic unit area of space (such as laptop, mobile phone when), easily makes
Connected between electronic unit between shielding tape, so as to be impacted to the normal work of electronic unit.
Utility model content
In order to overcome the conductive shield adhesive tape applied in existing electronic device field to be brought since its structure is limited in use
Various drawbacks, the utility model is provided substitutes the existing widely used aluminum plastic film of conductor shielding adhesive tape, copper foil using copper foil
, guidance quality thinner compared to plastic-aluminum film thickness is more preferably, easy to produce and process, ability is good for cross cutting, ratio of defects is low, finished product thickness is thin,
Flexibility is good, is easily bent in use, is more conducive to apply the electromagnetic shielding in FFC components, and space is narrow between electronic unit
Small place use, can be anti-oxidant coated with black conductive layer in conductive base layer (copper foil layer) outermost layer, overcomes existing
Conductive shield adhesive tape is easily aoxidized in use by air ambient outside since the conductive base layer on surface is directly exposed, subtracts significantly
Few service life, thus cause the hydraulic performance decline of shielding electromagnetic signal and the work to electronic equipment impact it is a kind of new
Conductive shield adhesive tape.
Technical solution is used by the utility model solves its technical problem：
A kind of novel conductive shielding tape, it is characterised in that be made of six layer structure, be release protection respectively from the bottom to top
