摘要： A retaining washer (100) prevents the rotation of a D-shaped shaft (106) which is mounted in a round hole (105a) of a housing (105). The retaining washer includes a substantially flat washer (101) having a hole (101a). A tapered tab (102) includes a wide end (102a) and a narrow end (102b). The tab is attached to the flat washer at the wide end such that the tab is substantially perpendicular to the flat washer. A gusset (103) is attached between the tab and the flat washer. The gusset includes a lower edge (103a) which is positioned at an obtuse angle (104) relative to the flat washer. The gusset indents into the housing (105b) and the tab is forced against the flat portion (106b) of the D-shaped shaft. The upper left and right edges of the tab cut into the wall of the housing hole (105c and 105d).

摘要： An improved housing assembly for housing miniaturized electrical or electronic apparatus, such as a radio receiver or monitor, is disclosed wherein a single piece housing is provided, open at the top for receiving an associated electrical chassis with self-contained battery compartment and a sound transducer. A control panel attached to the electrical chassis cooperates to overfit the open end of said housing to complete the overall assembly. The assemblage of the housing apparatus requires no screws, fasteners or special tools as the respective component parts effect a snap-fit with one another. A novel interlocking arrangement between chassis assembly and housing disguises the latching interfit therebetween, which nevertheless may be released by the insertion of a simple blade tool at the proper location. Complete shock mounting and protection from dust and dirt is effected by resilient gasket elements in cooperation with the housing and chassis assembly. A transparent lens cover is incorporated on a portion of the bottom panel to overlie an information placard referencing operational data but which, in addition, includes features which show if unauthorized access has been effected to the internal chassis assembly.
摘要翻译：公开了一种用于容纳小型化电气或电子设备的改进的壳体组件，例如无线电接收器或监视器，其中提供单件壳体，在顶部开口，用于接收具有独立电池室和声音传感器的相关联的电气底盘。连接到电气底盘的控制面板协同作用以使所述壳体的开口端部过渡以完成整个组件。由于相应的部件相互配合，因此外壳装置的组合不需要螺钉，紧固件或专用工具。底盘组件和壳体之间的新颖的互锁布置掩盖了它们之间的闩锁配合，然而可以通过将简单的刀片工具插入适当的位置来释放。完整的冲击安装和保护免受灰尘和污垢的影响由与壳体和底盘组件协作的弹性垫圈元件实现。透明透镜盖结合在底板的一部分上以覆盖参考操作数据的信息标牌，而且还包括显示未经授权的访问已经对内部底盘组件进行的特征。
