Embodiment Construction

[0019] The present invention provides a composite conductive rubber strip. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] see figure 1 , which is a schematic cross-sectional view of the installed composite conductive rubber strip according to the first embodiment of the present invention. As shown in the figure, the composite conductive rubber strip includes a conductive part 110 and a non-conductive part 100, and the composite conductive rubber strip is installed on the installation part 120 on. The non-conductive part is a solid circle, the conductive part is a cylindrical structure, and the wall thickness is less than 0.45mm (preferably...

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 [0001] The invention relates to an electronic system shielding device, in particular to a conductive rubber strip used in an electronic system. Background technique [0002] The wide application and development of electronic systems will inevitably lead to the continuous increase of the electromagnetic field level radiated by them in the space around them. That is to say, electronic systems inevitably work in the electromagnetic environment (EME), therefore, the adaptability of electronic systems in the electromagnetic environment must be addressed. [0003] The electronic system we want should neither radiate any electromagnetic waves to the outside, but also avoid the interference of external electromagnetic waves. EMC is usually solved by installing electronic system shielding devices. In addition, with the development of mobile communication technology, it is also necessary to consider the sealing problem in outdoor, high temperature and high humidity an...
