Summary of the invention
The purpose of this utility model is to provide a kind of electromagnetic signal gauze screen.
The purpose of this utility model is achieved in that
Electromagnetic signal gauze screen, the upper and lower side of the wire netting of the tubular that tinsel is made is provided with outer crimping shape
Become shielding cylinder, on the shielding cylinder outer wall between outer crimping interval be electrically connected with more than one be perpendicular to shield
Covering the metal connection post of drum outer wall, the outer end of metal connection post is provided with external screw thread or female thread.
Above-mentioned tinsel is the pure iron metal silk of anti-electromagnetic interference or red copper tinsel or stainless steel metal wire,
Metal connection post uses copper material or aluminium or stainless steel to make.
On the external cylindrical surface of above-mentioned metal connection post, circumference is evenly equipped with axially arranged anti-skidding projection or anti-skidding recessed
Groove.
By welding or riveting between above-mentioned metal connection post and shielding cylinder.
Above-mentioned metal connection post is one or two or three.
The mesh area of above-mentioned wire netting is less than 10mm2。
Above-mentioned outer crimping 360 degree of annular solids formed above of turnup from inside to outside.
The internal diameter of above-mentioned shielding cylinder is 50-250mm.
This utility model highlights and useful having the technical effect that compared to existing technology
1, this utility model is respectively provided with outer crimping at the upper and lower side of wire netting, and one is can to strengthen two ends to telecommunications
Number, the shield effectiveness of magnetic signal；Two is can be with the mechanical strength of reinforced metal mesh upper and lower side；Three be can in case
The only end wiry of the wire netting scratch to human body, clothes and accessory.
2, by welding or riveting between metal connection post of the present utility model and shielding cylinder, can be true
Protect and connect reliably, well conducting, reach to shield the purpose of relevant electromagnetic signal.
3, tinsel of the present utility model uses the strong pure iron metal silk of anti-electromagnetic interference or red copper tinsel or not
Rust steel tinsel is made, and anti-electromagnetic interference is strong, and the shield effectiveness of electromagnetic signal is good.
4, simple in construction of the present utility model, production cost is low, and the shield effectiveness of electromagnetic signal is good, it is adaptable to
Shielding to electromagnetic signal inside mobile communication, the machine room of national grid or transformer station.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model.
Detailed description of the invention
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings, sees Fig. 1:
Electromagnetic signal gauze screen, outside the upper and lower side of the wire netting 10 of the tubular that tinsel 11 is made is provided with
Crimping 13,14 forms shielding cylinder, interval electrical connection on the shielding cylinder outer wall between outer crimping 13,14
Having the more than one metal connection post 20 being perpendicular to shielding cylinder outer wall, the outer end of metal connection post 20 is provided with
External screw thread or female thread 22.
The above-mentioned pure iron metal silk that tinsel 11 is anti-electromagnetic interference or red copper tinsel or stainless steel metal
Silk, metal connection post 20 uses copper material or aluminium or stainless steel to make.
On the external cylindrical surface of above-mentioned metal connection post 20 circumference be evenly equipped with axially arranged anti-skidding protruding 21 or
Antiskid groove.
By welding or riveting between above-mentioned metal connection post 20 and shielding cylinder.
Above-mentioned metal connection post 20 is one or two or three；Metal connection post 20 uses copper material to make
Time, i.e. can reach conductive effect with a metal connection post 20 line of starting to exchange fire；Metal connection post 20 uses stainless
When steel make, need to reach conductive effect with three metal connection posts 20 line of starting to exchange fire simultaneously.
Mesh 12 area of above-mentioned wire netting 10 is less than 10mm2。
Above-mentioned outer crimping 13,14 360 degree of annular solids formed above of turnup from inside to outside, outer crimping 13,14
Outer diameter D 2 more than the external diameter of wire netting 10.
The internal diameter D1 of above-mentioned shielding cylinder is 50-250mm.
Above-described embodiment is only preferred embodiment of the present utility model, limits this practicality the most according to this new
The protection domain of type, therefore: all equivalence changes done according to structure of the present utility model, shape, principle
Change, within protection domain of the present utility model all should be covered by.
