工程塑料在电子设备减重方面的应用

Application of Engineering Plastic in Weight Reduction of Electronic Equipment

文中主要通过工程塑料的应用实现电子设备减重的目的。首先对电子机箱结构部分各个主要功能进行分析,讨论用工程塑料替换金属材料的可行性。可通过替换承力部件而非导热部件实现工程塑料的应用。然后针对工程塑料普遍不导电的问题,采用金属涂层提高其导电性。选用了几种不同的导电涂料进行实验,测试它们的导电性能及三防性能。最后采用塑料及尼龙材料,使用3D打印技术结合机械加工的方式,替换部分结构件,对某电子机箱进行了减重设计,并对制作的实物进行了力学及电磁兼容实验以验证该方法的有效性。

The main purpose of this paper is to reduce the weight of electronic equipment by adopting engineering plastics. Firstly, the main functions of the electronic chassis structure are analyzed and the feasibility of replacing metal materials with engineering plastics is discussed. The application of engineering plastic can be realized by replacing load-bearing parts instead of heat conducting parts. Then aiming at the problem that engineering plastic is generally non-conductive, metal coating is used to improve its conductivity. Several kinds of conductive coating are selected to test their conductivity and tri-proof property. Finally, some structural parts are replaced by plastic(PC) and nylon(PA) materials using 3D printing technology combined with machining. Thus the weight reduction design of an electronic chassis is realized. And the mechanical and electromagnetic compatibility experiments for the prototype are carried out to verify this method.
