Abstract
The invention provides a composite conductive rubber strip. Higher compressibility is brought by using a thin-wall hollow conductive part, so more reliable electromagnetic shielding performance can be produced; meanwhile, due to the composite shape of a non-conductive part and a conductive part, the composite conductive rubber strip provided by the invention has high water-tight performance and air-tight performance. On the whole, the composite conductive rubber strip provided by the invention can effectively provide water-tightness, air-tightness and electromagnetic shielding for an electronic system, and is particularly suitable for sealing the electronic system working in severe environment, such as high temperature environment, high moisture environment and the like.
Description
Technical field
The present invention relates to the electronic system screening arrangement, particularly a kind of conductive rubber strip that is used for electronic system.
Background technology
The extensive use of electronic system and development must cause their continuous increases at the electromagnetic field level of its surrounding space radiation.That is to say that therefore electronic system work in electromagnetic environment (EME) inevitably, must solve the adaptive capacity of electronic system in electromagnetic environment.
We should can avoid the interference of external electromagnetic ripple again neither to any electromagnetic wave of external radiation at desirable electronic system.Normally solve electromagnetic compatibility, in addition,, also need consider out of doors, the sealing problem when being in adverse circumstances such as hot and humid along with the development of mobile communication technology through the electronic system screening arrangement is installed.
The technical scheme of head it off in the prior art always has the some shortcomings part.Such as: sealing property is bad, and cost is too high, and capability of electromagnetic shielding becomes very poor or the like when seal deformation is big.
Therefore, press for a kind of seal that watertight, steam packing and electromagnetic shielding can be provided for electronic system effectively, especially be suitable for the sealing of the electronic system of in adverse circumstances such as hot and humid, working.This is present problem demanding prompt solution.
Summary of the invention
Weak point in view of above-mentioned prior art the object of the present invention is to provide a kind of electromagnet shield effect that both had, the composite conducting rubber bar that has watertight, steam packing performance again.
In order to achieve the above object, the present invention has taked following technical scheme:
A kind of composite conducting rubber bar is composited by non-conductive part and current-carrying part, and wherein, said current-carrying part is a tubular structure, and wall thickness is less than 0.45mm.
Described composite conducting rubber bar, wherein, said non-conductive part part coated with conductive part.
Described composite conducting rubber bar, wherein, said non-conductive part is an elastic rubber layer.
Described composite conducting rubber bar, wherein, said non-conductive part is solid or hollow.
Described composite conducting rubber bar, wherein, the material of said non-conductive part is a kind of in silicon rubber, fluorosioloxane rubber, ethylene propylene diene rubber, the neoprene.
Described composite conducting rubber bar, wherein, the material of the rubber substrate of said current-carrying part is a kind of in silicon rubber, fluorosioloxane rubber, ethylene propylene diene rubber, the neoprene; Conductive filler is a kind of in nickel coated graphite powder, silver-colored aluminium powder, silver-bearing copper powder, silver-colored nickel powder, the silver glass powder.
Compared to prior art, composite conducting rubber bar provided by the invention adopts the thin-walled hollow current-carrying part to bring better compressibility, has produced capability of electromagnetic shielding more reliably therefrom; Simultaneously because the compound shape of non-conductive part and current-carrying part makes composite conducting rubber bar provided by the invention have better watertight, steam packing performance.Generally speaking, composite conducting rubber bar provided by the invention can be effectively for electronic system provides watertight, steam packing and electromagnetic shielding, especially is suitable for the sealing of the electronic system of in adverse circumstances such as hot and humid, working.

The specific embodiment
The present invention provides a kind of composite conducting rubber bar, and is clearer, clear and definite for making the object of the invention, technical scheme and effect, below with reference to accompanying drawing and give an actual example to further explain of the present invention.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
See also Fig. 1; It is the schematic cross-section after the composite conducting rubber bar of first embodiment of the invention is installed; As shown in the figure, the composite conducting rubber bar comprises current-carrying part 110 and non-conductive part 100, and the composite conducting rubber bar is installed on the installing component 120.Non-conductive part is a solid circles, and current-carrying part is a tubular structure, and wall thickness is less than 0.45mm (being preferably 0.3mm), and this kind shape has better compressibility, has produced capability of electromagnetic shielding more reliably therefrom.
Further; Non-conductive part 100 part coated with conductive parts 110, this kind structure makes the composite conducting rubber bar when mounted, even overall dimensions is slightly larger than the size of mounting groove; Also can touch installing component 120 fully; Play better sealing function, electric conductivity is more reliable, and water proofing property is better.
For the sealing property and the capability of electromagnetic shielding of composite conducting rubber bar of the present invention better are described, the spy tests the composite conducting rubber bar of this embodiment: test its deformation quantity and its resistance and the relation that applies external force.It is as shown in Figure 4 to obtain its result curve.
Please continue to consult Fig. 2, Fig. 2 is the schematic cross-section after the composite conducting rubber bar of second embodiment of the invention is installed, and said non-conductive part is the D shape of falling; The cross section of said current-carrying part 110 is a ring-type, and wall thickness is 0.35mm.After this kind shape is installed on the installing component 120, also have good compressibility, produced capability of electromagnetic shielding more reliably therefrom.
Fig. 3 is the schematic cross-section of the composite conducting rubber bar of third embodiment of the invention, and the cross sectional shape of said non-conductive part 100 is the hollow D shape of falling, and the cross section of current-carrying part 110 is a ring-type.
Said non-conductive part is an elastic rubber layer, can be made up of a kind of in silicon rubber, fluorosioloxane rubber, ethylene propylene diene rubber, the neoprene; The rubber substrate of said current-carrying part can be the same with non-conductive part; The filling of its conductive filler can comprise a variety of, such as: nickel coated graphite powder (Ni/C), silver-colored aluminium powder (Ag/Al), silver-bearing copper powder (Ag/Cu), silver-colored nickel powder (Ag/Ni), silver glass powder (Ag/Glass) etc.
