摘要： 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.

摘要翻译： 用于车辆应用的轻量级无线电/ CD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壳体和正面接口，其被模制以提供细节以接收音频设备，如回放机构（如果需要）和无线电接收器，以及 作为电气控制和显示所需的电路板。 外壳和正面接口为复合结构，包括已经通过模制操作预先形成轮廓的镶嵌模制导电丝网。 金属丝网通过暴露的金属丝网垫和相邻的接地夹提供EMC，RFI，BCI和ESD屏蔽和电路板的接地。 PCB结构分为第一板，其承载具有适合于大批量生产的表面安装配置中的公共电路部件，以及第二板，其以波焊焊棒安装配置的方式承载特定于应用的电路部件。 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。 主要部件和组件通过整体引导和连接功能自我互连，实现“滑动锁定”和“卡锁”自动互连。 无线电架构包括改进的按钮，采用4杆活动铰链和前装饰装饰钮扣。
