随着电子技术的迅猛发展， 电子产品层出不穷， 对电子产品的静电防护 及电磁波屏蔽功能的要求也在日益提高。 根据电子线路的工作原理可知， 只要有交变电流存在， 就必然会产生电磁波辐射。 电磁波辐射对信号的完 整性以及电路的可靠性等均会造成危害， 因此， 衍生出各种电磁波屏蔽的 方法。 With the rapid development of electronic technology, electronic products are emerging one after another, and the requirements for electrostatic protection and electromagnetic wave shielding of electronic products are also increasing. According to the working principle of the electronic circuit, as long as there is an alternating current, electromagnetic wave radiation is inevitably generated. Electromagnetic wave radiation can cause damage to the integrity of the signal and the reliability of the circuit. Therefore, various electromagnetic wave shielding methods are derived.
目前， 电磁波屏蔽的方法主要分为电屏蔽和磁屏蔽； 其中， 所述电屏蔽 是使用导电材料将电磁辐射区域覆盖或包裹， 形成类似法拉第笼的结构， 通过屏蔽电场的方式将电磁波屏蔽； 所述磁屏蔽是釆用磁屏蔽材料， 如铁 氧体等， 通过屏蔽磁场的方式将电磁波屏蔽。 At present, the method of electromagnetic wave shielding is mainly divided into electrical shielding and magnetic shielding; wherein the electrical shielding is to cover or wrap the electromagnetic radiation region with a conductive material to form a structure similar to a Faraday cage, and shield the electromagnetic wave by shielding the electric field; The magnetic shielding is a magnetic shielding material, such as ferrite, which shields electromagnetic waves by shielding a magnetic field.
现有的电屏蔽材料包括硬性金属良导体和柔性导电材料， 所述硬性金 属良导体可被加工成固定形状的腔体， 再将需被屏蔽的电路置于其中； 所 述柔性导电材料可为导电布或导电金属薄膜等， 由于柔性导电材料具有可 塑性且容易加工装配的特点， 被广泛应用于移动终端等电子产品中。 The existing electric shielding material comprises a hard metal good conductor and a flexible conductive material, the hard metal good conductor can be processed into a fixed shape cavity, and the circuit to be shielded is placed therein; the flexible conductive material can be A conductive cloth or a conductive metal film or the like is widely used in electronic products such as mobile terminals because of its plasticity and ease of processing and assembly.
在柔性导电材料的应用过程中， 对柔性导电材料安装的牢固性和导电 的可靠性有一定要求。 对应安装的牢固性， 现有的解决办法为： 将固定胶 涂在柔性导电材料的一面， 将该涂有固定胶的一面粘贴在需屏蔽的区域上。 但是， 由于固定胶不是良导体， 无法使柔性导电材料和被屏蔽区域周围的 地平面良好接触， 因此， 如果只用固定胶只能实现安装的牢固性， 而无法
满足导电的可靠性。 In the application process of flexible conductive materials, there are certain requirements for the firmness of the installation of flexible conductive materials and the reliability of electrical conduction. Corresponding to the firmness of the installation, the existing solution is: Apply the fixing glue to one side of the flexible conductive material, and stick the side coated with the fixing glue on the area to be shielded. However, since the fixing glue is not a good conductor, the flexible conductive material cannot be in good contact with the ground plane around the shielded area. Therefore, if only the fixing glue is used, only the firmness of the mounting can be achieved, and Meet the reliability of conduction.
为了解决这一问题， 已有的方法是在固定胶中掺杂金属颗粒、 或导电 纤维来改善固定胶导电性差的问题， 但由于离散的金属颗粒、 或导电纤维 周围也包裹着固定胶， 需对柔性导电材料施加一定的压力， 以保证金属颗 粒将被屏蔽区域和柔性导电材料进行连接。 但不同的压力大小对应的导电 效果也是不同的， 而在使用过程中压力大小难以控制， 因此， 很难达到对 柔性导电材料导电可靠性的要求。 发明内容 In order to solve this problem, the existing method is to dope metal particles or conductive fibers in the fixing glue to improve the problem of poor conductivity of the fixing glue, but since the discrete metal particles or the conductive fibers are also wrapped around the fixing glue, A certain pressure is applied to the flexible conductive material to ensure that the metal particles will be joined by the shielded area and the flexible conductive material. However, the different conductive pressures have different electrical conductivity effects, and the pressure is difficult to control during use. Therefore, it is difficult to meet the requirements for the conductive reliability of flexible conductive materials. Summary of the invention

The structure of the flexible conductive material of the present invention will be described below by taking the protrusion of the flexible conductive material as a cubic structure and arranging two kinds of meshes on one side of the flexible conductive material substrate as an example.
图 1为本发明柔性导电材料基板的立体结构示意图， 如图 1所示， 包 括： 设置于柔性导电材料基板单侧或双侧的凸起网格和固定胶网格； 其中， 所述凸起网格， 由若干个纵横排列的凸起组成， 与被屏蔽区域周围的 地平面连接， 实现柔性导电材料的导电性； 所述被屏蔽区域周围的地平面 位于图 1 中所示凸起网格所在平面之上， 且紧贴凸起网格， 这里， 为了清 楚表示凸起网格和固定胶网格的结构， 未在图 1 中给出被屏蔽区域周围的 地平面的结构。 1 is a schematic perspective view of a flexible conductive material substrate according to the present invention. As shown in FIG. 1, the method includes: a convex mesh and a fixed glue grid disposed on one side or both sides of a flexible conductive material substrate; wherein the protrusion a grid consisting of a plurality of vertically and horizontally arranged projections connected to a ground plane around the shielded area to achieve electrical conductivity of the flexible conductive material; the ground plane around the shielded area is located in the raised grid shown in FIG. Above the plane, and close to the convex grid, here, in order to clearly show the structure of the convex grid and the fixed glue grid, the structure of the ground plane around the shielded area is not shown in FIG.
所述固定胶网格， 固定在被屏蔽区域上， 用于实现柔性导电材料的安
装牢固性。 The fixing glue mesh is fixed on the shielded area for realizing the flexible conductive material Firmness.
图 1中所示 11为柔性导电材料基板； 12为柔性导电材料基板的一个凸 起， 为立方体结构； 13为固定胶网格。 其中， 所述柔性导电材料凸起 12重 复出现， 若干纵横排列的凸起构成柔性导电材料凸起网格， 且所述柔性导 电材料凸起 12的表面上没有固定胶； 所述柔性导电材料基板 11和柔性导 电材料凸起网格是一体的， 相互之间具有良好的导电性能。 11 is a flexible conductive material substrate; 12 is a convex of a flexible conductive material substrate, which is a cubic structure; and 13 is a fixed adhesive mesh. Wherein, the flexible conductive material protrusions 12 are repeatedly formed, and the plurality of vertically and horizontally arranged protrusions constitute a convex conductive mesh of the conductive material, and the surface of the flexible conductive material protrusion 12 has no fixing glue; the flexible conductive material substrate 11 and the flexible conductive material convex grid are integrated, and have good electrical conductivity between each other.
本发明所述固定胶填充于所述柔性导电材料凸起网格之间的沟槽中， 形成固定胶网格 13 , 且所述柔性导电材料凸起 12的表面上没有固定胶， 固 定胶网格 13不同于现有的整片覆盖的固定胶， 因此可避免柔性导电材料被 固定胶隔离， 不会影响柔性导电材料的导电性。 The fixing glue of the present invention is filled in the groove between the convex grids of the flexible conductive material to form the fixing glue mesh 13 , and the surface of the flexible conductive material protrusion 12 has no fixing glue, and the fixing glue net The grid 13 is different from the existing full-covering fixing glue, so that the flexible conductive material can be prevented from being isolated by the fixing glue without affecting the conductivity of the flexible conductive material.
在实际应用过程中， 通过所述固定胶网格 13将柔性导电材料粘贴固定 在被屏蔽区域上， 安装牢固； 同时， 柔性导电材料凸起网格和被屏蔽区域 周围的地平面良好接触， 实现柔性导电材料良好的导电性。 In the actual application process, the flexible conductive material is adhered and fixed on the shielded area through the fixed adhesive mesh 13, and the installation is firm; at the same time, the convex conductive mesh of the flexible conductive material is in good contact with the ground plane around the shielded area, thereby realizing The flexible conductive material has good electrical conductivity.
图 1 中所示 S为柔性导电材料相邻凸起间的距离， 该距离依据需被屏 蔽的电磁波的波长来设置， 具体的， 设被屏蔽的电磁波的波长为 λ, 那么， 可设置 S与 λ成正比关系； λ越长， 设置的 S也越大， 两者间的比例系数可 任意设置； 当然， 对同一 λ来说， S越小， 屏蔽效果越好。 S is the distance between adjacent protrusions of the flexible conductive material, which is set according to the wavelength of the electromagnetic wave to be shielded. Specifically, the wavelength of the shielded electromagnetic wave is λ, then S and λ is proportional to the relationship; the longer λ is, the larger the set S is, and the proportional coefficient between the two can be set arbitrarily; of course, for the same λ, the smaller S is, the better the shielding effect is.
图 1 中所示 Τ为固定胶网格的厚度， 也为柔性导电材料凸起的厚度。 当然， 所述固定胶网格与柔性导电材料凸起的厚度可稍有不同， 即： 两者 大致在同一平面上， 两者间的厚度差约在总厚度的 10%左右； 当然， 根据 材料的不同， 所述厚度差也会有所变化。 因为柔性导电材料和固定胶具有 一定的伸缩性， 或者说弹性， 只要柔性导电材料固定在被屏蔽区域上时， 两者均能良好接触被屏蔽区域即可。 在实际应用中， 可通过调整 Τ的大小 实现安装的牢固性和导电良好性之间的平衡， 例如： 如果 Τ小一些， 导电 性则好些， 而牢固性就差些； 如果 Τ大一些， 牢固性则较好， 而导电性就
较差。 The thickness shown in Figure 1 is the thickness of the fixed glue grid, which is also the thickness of the convex of the flexible conductive material. Of course, the thickness of the fixed adhesive mesh and the flexible conductive material protrusion may be slightly different, that is, the two are substantially on the same plane, and the thickness difference between the two is about 10% of the total thickness; The difference in thickness will also vary. Because the flexible conductive material and the fixing adhesive have certain flexibility, or elasticity, as long as the flexible conductive material is fixed on the shielded area, both can well contact the shielded area. In practical applications, the balance between the firmness of the installation and the good electrical conductivity can be achieved by adjusting the size of the crucible, for example: if the size is smaller, the conductivity is better, and the firmness is worse; if it is larger, it is firmer. Sex is better, and conductivity is Poor.
