Abstract
The utility model relates to a multi-strand shielding film with good shielding functions to external signals, which comprises a film provided with an in-built metal mesh formed by metal wires. The shielding film has the advantages that 1 the shielding film has good and reliable shielding effects on external signals; 2 the structure is simple and production cost is low; and 3 strength of extension of the film is improved effectively.
Description
Technical field
The utility model relates to and a kind of extraneous signal is had the screened film of good function of shielding, belongs to field of thin film fabrication.
Background technology
CN2619893Y, title " translucent antistatic multiply screened film ", film is formed by four layers, and ground floor is an anti-static coating, and the second layer is the aluminum plated PET screen, and the 3rd layer is polyolefin hot-seal layer, the 4th layer is anti-static coating.Advantage is to prevent static effectively to electronic devices and components, the especially infringement of more and more tangible data handling system of trend toward miniaturization and communication class electronic product, but not good to the shield effectiveness of extraneous signal, complex structure, manufacturing cost height.
The utility model content
Purpose of design: avoid the weak point in the background technology, design a kind of screened film that extraneous signal is had good function of shielding.
Design: in order to realize above-mentioned purpose of design.Film is built-in with the design of the wire netting that is made of sub-thread or strands of metal wire line, is major technique feature of the present utility model.The purpose of doing like this is: because the strands of metal wire net not only has good anti-interference function, and it can play shielding action to extraneous signal effectively, therefore the utility model is built-in with the strands of metal wire net at film, make film have good function of shielding, expanded the scope of application of film.
Technical scheme: a kind of multiply screened film, it comprises film, described film is built-in with the wire netting that is made of tinsel.
The utility model is compared with background technology, and the one, extraneous signal is had good shield effectiveness reliably; The 2nd, simple in structure, low cost of manufacture; The 3rd, improved the tensile strength of film effectively.
Description of drawings
Fig. 1 is the structural representation of multiply screened film.
Fig. 2 is the cross section structure schematic diagram of Fig. 1.
Fig. 3 is the structural representation in sub-thread screened film cross section.
Embodiment
Embodiment 1: with reference to accompanying drawing 1-3.A kind of multiply screened film, it comprises film 1, described film 1 is built-in with the wire netting 2 that is made of tinsel.Described wire is elementary wires or is made of two or two above elementary wires lines that its manufacture craft is a prior art, is not described herein at this.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection range of the present utility model.
Claims (2)
1. screened film, it comprises film, it is characterized in that: described film is built-in with the wire netting that is made of tinsel.
2. screened film according to claim 1 is characterized in that: described wire is elementary wires or is made of two or two above elementary wires lines.
