Abstract
An electromagnetic shielding strip comprises a strip-shaped body (1) which longitudinally extends and consists of conductive sheets, wherein the cross section of the strip-shaped body (1) is 'C'-shaped, and a plurality of transversely-extended grooves (13) are arranged in the longitudinal direction of the strip-shaped body (1). The strip-shaped body (1) can be a rectilinear strip-shaped body, and also can be an arched strip-shaped body which is bent along the longitudinal direction. Each conductive sheet is made from a conductive fabric or conductive plastic, and the conductive fabric is a conductive knitted fabric or a conductive non-woven fabric. The electromagnetic shielding strip has the advantages of being simple in structure, low in production cost and light in weight, and plays a good role on shielding EMI/RFI after being combined with a wall type or integrated outer-shell type electromagnetic shielding layer of equipment.

[background technology]
Electronic equipment can generate electromagnetic waves in its some parts, and this electromagnetic wave meeting radiation is also disturbed other parts of this electronic equipment and other electronic equipments outside this electronic equipment.This electromagnetic interference (EMI)/radio frequency interference (RFI) may cause the change of signal of interest or loss fully, maybe can not work thereby the electronic equipment that is disturbed is made mistakes.In order to reduce the harmful effect of EMI/RFI, between two parts of regular meeting, establish electromagnetic wave shielding, to absorb and reflection EMI/RFI energy at electronic circuit.This electromagnetic wave shielding is generally taked the form of wall type or complete shell, and be placed on electronic circuit the generation electromagnetic signal that part around and be placed on electronic circuit the influence that is subject to electromagnetic signal that part around.For example, the element of electronic circuit or printed circuit board (PCB) (PCB) is surrounded by shielding part usually, so that EMI/RFI is confined in its source, and makes near other devices in this EMI/RFI source and is isolated.The EMI/RFI shielding part can comprise and is configured to provide EMI/RFI the conductive gasket of shielding.But owing on the electronic equipment many source of leaks are arranged: positions such as the slit of different piece junction, ventilating opening, display window, button, indicator light, cable, power line for example.In order to shield EMI/RFI effectively at these positions, be the continuous conductive path that runs through these gaps by foundation, placement electromagnetic shielding bar is realized in conductive path.The electromagnetic shielding bar of prior art includes what is called ' golden finger ' electromagnetic shielding bar, helix tube electromagnetic shielding bar and the open circles foam of metal structure and does substrate, and skin is the hollow foam electromagnetic shielding bar of conducting metal.But this of prior art two a little electromagnetic shielding bar production costs are higher, and particularly the electromagnetic shielding bar of metal also has the big shortcoming of weight.
[utility model content]
At the shortcoming of prior art, the purpose of this utility model be to provide a kind of simple in structure, production cost is low and lightweight electromagnetic shielding bar.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of electromagnetic shielding bar is provided, the strip shape body that constitutes by conductive foil that comprises longitudinal extension, it is characterized in that: the cross section of described strip shape body is for ' C ' shape, and along the groove that some horizontal expansions are vertically arranged 13 of this strip shape body.
Described strip shape body can be rectilinear strip shape body, can also be the arc strip shape body along its buckling.
Described conductive foil can be conductive fabric or conductive plastics, and described conductive fabric can be conductive braided fabric cloth or conduction nonwoven fabrics.Described conductive braided fabric cloth, conduction nonwoven fabrics or conductive plastics can be coating or electroplated metal layers on woven cloth, nonwoven fabrics or plastic basis material.Described metal level can be copper layer or other metal levels.
