Abstract: An electronic device with electromagnetic interface protection including a first printed circuit board, a second printed circuit board, a shielding member, and a first fixing member is provided. The shielding member is located between the first printed circuit board and the second printed circuit board. A first end of the shielding member is fixed to the first printed circuit board, and the first fixing member is buckled to a second end of the shielding member so that the shielding member is fixed to the second printed circuit board.

Abstract: A lightweight radio/CD player for vehicular application includes a case and frontal interface formed of polymer based material molded to provide details to accept audio devices and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. The PCB architecture integrally forms a resilient beam portion adjacent an edge thereof carrying a grounding pad.

Abstract: A lightweight radio/CD player for vehicular application is virtually “fastenerless” and includes a case and frontal interface formed of polymer based material that is molded to provide details to accept audio devices such as playback mechanisms (if desired) and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides EMC, RFI, BCI and ESD shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. The PCB architecture is bifurcated into a first board carrying common circuit components in a surface mount configuration suitable for high volume production, and a second board carrying application specific circuit components in a wave soldered stick mount configuration. The major components and subassemblies are self-fixturing during the final assembly process, eliminating the need for dedicated tools, fixtures and assembly equipment. The major components and subassemblies self-interconnect by integral guide and connection features effecting “slide lock” and “snap lock” self-interconnection. The radio architecture includes improved push buttons employing 4-bar living hinge linkage and front loaded decorative trim buttons.

The case is of composite structure, including an insert molded electrically conductive wire mesh screen. The wire mesh provides shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. Side wall closure members define self-engaging attachment features for affixing to the case, providing electrical self-grounding with the wire screen and thermal grounding with internal power devices. The major components and subassemblies are self-fixturing during the final assembly process, eliminating the need for dedicated tools, fixtures and assembly equipment.

Abstract translation: 用于车辆应用的轻便音频播放器实际上是“无紧固件”，并且包括由聚合物基材料形成的折叠盒，以形成用于接收音频设备的细节以及用于电气控制和显示所需的电路板。 这种情况是复合结构，包括一个插入模制的导电丝网。 丝网通过暴露的金属丝网垫和相邻的接地夹提供电路板的屏蔽和接地。 侧壁关闭构件限定自身接合附件特征，用于固定到壳体，提供与电线屏蔽的电自身接地和与内部功率器件的热接地。 主要组件和组件在最终组装过程中是自固定的，无需专用工具，夹具和组装设备。
