在微波射频识别应用中， 通常将此种标签粘贴在金属物体表面，一般标签本身的 厚度至少为 3mm, 所以放置后会在金属物体表面产生一定的厚度， 而此厚度的产生 就会给标签带来很多问题， 比如标签粘贴不牢或者因进水暴晒等环境条件而产生脱 落， 也有可能因为重物撞击而损坏， 从而使其应用效果不佳。
因而， 目前在实际应用中， 一般的解决方法是将标签嵌入到金属物体内， 然后在 金属物体内填充环氧胶或硅胶等胶体来固定标签， 此时， 标签就能避免裸露在金属外 面， 但是， 在使用过程中， 由于对胶体选择会产生差异性， 从而影响到标签性能。 因 为环氧胶等胶体的介电常数和介质损耗参数的不同会影响标签性能，使标签性能不稳 定。 同时还因为环氧胶等胶体使用的不方便性也会极大的提高使用者的使用成本。 发明内容

顶壳 1、 防水双面胶 3以及柱状基体 8也可通过连接组件固定， 该连接组件包括 有凸设于柱状基体 8顶面的连接柱 6以及分别纵设于所述防水双面胶 3和顶壳 1的连 接通孔 4、 2， 所述连接柱 6与连接通孔 4、 2相配合形成滑动连接。 所述连接柱 6呈 中空状， 中空部分自标签本体 5的上表面延伸至柱状基体 8的表层。连接柱 6与连接 通孔 4、 2均对称分布于标签本体 5的两侧。
柱状基体 8的顶面设有凹槽 7， 标签本体 5即内嵌于该凹槽 7中， 凹槽 7的形状 与标签本体 5的外缘相配合。凹槽 7与标签本体 5为间隙配合， 即凹槽 7的尺寸略大 于标签本体 5的尺寸使得标签本体 5与防水双面胶 3的接触面积增大。沿柱状基体 8 的外周壁轴向延伸有环状突起 10; 环状突起 10为防水设计， 且与柱状基体 8是一个 整体； 环状突起 10与连接柱 6等高， 而所述连接柱 6的高度与防水双面胶 3和顶壳 1叠加在一起的高度相同。 安装的时候， 连接柱 6穿过连接通孔 2、 4, 直到与顶壳 1 表面平齐。 本发明的较佳实施方式的顶壳 1表面， 连接柱 6， 环状突起 10形成一个 平整的平面。
柱状基体材料是导电或者不导电的， 从而使无线射频标签获得最佳读取距离。 如图 6所示， 基于本发明的一实施例： 可以在被嵌入的物体 1 1上幵设螺纹与柱
替换页 （细则第 26条) 状基体 8上的螺纹 9相配合， 标签本体即可完全地、 平整地嵌入。
如图 7所示， 基于本发明的另一实施例： 顶壳覆盖标签本体， 所述顶壳的表面积 大于标签本体的表面积， 本实施例中将顶壳替换为面积更大的螺帽 12， 螺帽 12是顶 壳在面积上的延伸， 在螺帽 12上具有和柱状基体层上的连接柱同样位置和同样大小 的通孔。 并且， 所述螺帽 12的截面面积大于柱状基体 8的平面面积。
在进行标签安装的时候， 可以在被嵌入的物体 1 1上开设螺纹与柱状基体 8上的 螺纹 9相配合， 使用配套的螺丝刀插入到安装孔中旋转， 标签即可完全地、 平整地嵌 入。 例如， 电脑机箱。
该无线射频识别标签可以按照螺丝的安装方式进行， 不需要粘贴背胶， 并可以反 复拆取和安装， 能够与被嵌入物体良好的结为一体， 外型美观， 减小标签因为粘贴不 牢或因进水暴晒等环境条件而脱落的几率。
另外， 我们还知道， 上述连接通孔的形状还可以是圆形、 椭圆形、 多边形和不规 则图形中的任意一种， 这些都是本领域技术人员所知晓的。
再另外的实施方式中，顶壳和柱状基体间可以用强力胶水或超声波焊接等方式连 接， 实际应用中双面胶， 强力胶水和焊接的厚度可以忽略不计。
本发明的无线射频识别标签安装到金属里后其性能非常好，比如测定的最大读取 距离为放置在金属表面时最大读取距离的 70%以上。而且不受外界环境影响，标签的 性能始终保持一致性， 以此保证标签的高稳定性。
上述具体实施例仅仅是示例性的， 在本发明的上述教导下， 本领域技术人员可以 在上述实施例的基础上进行各种改进和变形，而这些改进或者变形落在本发明的保护 范围内。本领域技术人员应该明白， 上面的具体描述只是为了解释本发明的目的， 并 非用于限制本发明。 本发明的保护范围由权利要求及其等同物限定。
