Abstract
The invention provides an electromagnetic shielding stripe which comprises a stripe-shaped body (1) which lengthways extends and consists of conductive sheets, wherein the cross section of the stripe-shaped body (1) is 'C'-shaped, and a plurality of transversely-extended grooves (13) are arranged in the lengthways direction of the stripe-shaped body (1). The stripe-shaped body (1) can be a rectilinear stripe-shaped body, and also can be an arched stripe-shaped body which is bent along the lengthways 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 stripe 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 (electro-magnetic interference/radio frequency interference) after being combined with a wall type or integrated outer housing type electromagnetic shielding layer of equipment.
Description
[technical field]
The present invention relates to equipment or element to the shielding in electric field or magnetic field, relate to electromagnetic interference (EMI)/radio frequency interference (RFI) shielding device, relate more specifically to the electromagnetic shielding bar.
[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 fully loss, maybe can not work thereby the electronic equipment that is disturbed is made mistakes.In order to reduce the harmful effect of EMI/RFI, often can between two parts of electronic circuit, establish electromagnetic wave shielding, to absorb and reflection EMI/RFI energy.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 impact 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 the EMI/RFI 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.In order effectively to shield EMI/RFI 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 large shortcoming of weight.
[summary of the invention]
For the shortcoming of prior art, the object of the present invention is to provide a kind of simple in structure, production cost is low and lightweight electromagnetic shielding bar.
The technical solution adopted for the present invention to solve the technical problems is: a kind of electromagnetic shielding bar is provided, the strip shape body that is consisted of 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 at woven cloth, nonwoven fabrics or plastic basis material coating or electroplated metal layer.Described metal level can be copper layer or other metal levels.
Described conductive foil can comprise outer conductive layer and the internal layer supporting layer that conductive braided fabric cloth, conduction nonwoven fabrics or conductive plastics form, 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 at woven cloth, nonwoven fabrics or plastic basis material coating or electroplated metal layer.Described metal level can be the copper layer.Described supporting layer can be PET or other plastics.
Can adhere near the gap leakage of equipment body with conducting resinl when the present invention uses, the electro-magnetic screen layer with body and cover or screen under the compressing of cover or screen etc. is unified into an integral body, then can play good shielding action to EMI/RFI.
Can in body, along gap leakage arrangement of grooves of the present invention be set, so that equipment keeps original attractive in appearance after laying the present invention.
The invention has the beneficial effects as follows: simple in structure, production cost is low and lightweight, combine with the electro-magnetic screen layer of the wall type of equipment or complete shell form, can play good shielding action to EMI/RFI.
