把显示器挂在机箱侧面板上

If we need to remove the side panel on our desktop computers, we usually do not give much thought to the series of flexible spring tabs around the outer edge of the case, but what are they actually there for? Today’s SuperUser Q&A post has the answer to a curious reader’s question.

如果我们需要卸下台式计算机上的侧面板，通常对外壳外缘周围的一系列弹性弹簧片并不需要多加考虑，但是它们实际上有什么用？ 今天的“超级用户问答”帖子回答了一个好奇的读者的问题。

问题 (The Question)

SuperUser reader VAN wants to know what the flexible spring tabs on the side of computer cases are for:

超级用户阅读器VAN想知道电脑机箱侧面的弹性弹簧片用于：

Many computer cases have these holes/cut-outs/tabs on the outer edge of the frame. What are they for?

许多计算机机箱的框架外边缘上都有这些Kong/切口/凸耳。 他们是干什么的？

What are the flexible spring tabs on the side of computer cases for?

机箱侧面的弹性弹簧卡扣有哪些用途？

答案 (The Answer)

SuperUser contributor VAN has the answer for us:

超级用户贡献者VAN为我们提供了答案：

The flexible spring tabs are definitely made to reduce gaps around the outside of the computer case and provide better grounding, both of which reduce EMI emissions. The relevant patents covering the chassis and peripheral cages discuss the “feature”.

灵活的弹簧卡舌绝对可以减少计算机机箱外部的间隙并提供更好的接地，从而减少EMI辐射。 涉及底盘和外围机箱的相关专利讨论了“功能”。

Here are some additional references that support the dampening idea/theory as well. Although they are not for the chassis per se, one patent covering media drives mentions vibration dampening and a second patent for a hard disk frame mentions both uses.

这里还有一些支持阻尼思想/理论的参考文献。 尽管它们本身并不是用于机箱，但是一项涉及介质驱动器的专利提到了减振，而针对硬盘架的第二项专利提到了这两种用途。
