技术问答

LAIRD（莱尔德科技）是全球领先指形簧片生产商，该公司开发的多种屏蔽和接地垫片产品，获得了国际性的专利。夹式指形簧片系列采用的是一体式卡簧固定的安装结构，主要是设计用于不能使用粘合剂安装的应用环境，例如高温环境等。

图1 夹式指形簧片全系列产品实物图

这种夹式指形簧片产品的EMI屏蔽性能与粘贴安装类簧片相同，在100MHz平面电磁波的条件下，屏蔽效能达到100dB以上。按照产品的机械结构进行分类，夹式指形簧片可分为三个大类，D形卡簧的SNAP-TITE^®系列，T形卡簧的GRIP-TITE^®系列，还有迷你夹式指形簧片系列。

上图为SNAP-TITE^®系列夹式指形簧片产品的结构示意图，该系列的固定卡簧为D形结构，可以紧扣住安装表面的穿孔或定位槽。优点是可以形成全方向的强大抓握力，结构可靠性和接触性好，具有十分良好的导电性能。

上图为GRIP-TITE^®系列夹式指形簧片的结构示意图，固定卡簧为T形结构，通常用于较软的安装面材料，例如铝或电镀塑料等。T形卡簧结构可以紧紧的咬住安装表面，固定住簧片的同时，还能保证良好的导电性。

最后是迷你夹式指形簧片系列，有97-645和97-646两个型号，是Laird为了最新的轻薄材料应用需求而专门设计的新型产品。该系列簧片的安装结构是迷你型的D形卡簧，具有夹式簧片系列中的最低压缩应力，并且几乎没有永久压缩变形量，在高达60%的压缩量条件下，仍能恢复100%的原始高度。高性能铍铜的材质，具有最佳的导电性和机械性能，循环寿命高达50,000次以上，确保无断裂、无磨损或永久压缩变形。

夹式指形簧片的典型应用：

• 高温屏蔽应用

• 屏蔽机箱，屏蔽设备舱

• 铝质表面，电镀塑料表面

• 小型电信设备

• 便携式设备

• 轻薄型应用环境
