摘要： A detachable low profile mounting clip arrangement suitable for use with a portable hand-held electronic apparatus such as a paging receiver, includes a housing having a slot. A base member has a hook attached to one end and a pair of apertures at the other end. The hook engages in the slot of the housing while the apertures spring over a pair of wedge shape protuberancies in the housing and snap into place. A mounting clip or lanyard is attached to the base member.

摘要： An improved socket assembly is disclosed which is especially suited for use in printed circuitry with dense configuration of components in limited areas of surface. The socket is mounted on an associated printed circuit board and allows horizontal insertion of vertically stacked keyed components, from either side of the socket assembly. The socket assembly further includes a non-metallic insert, consisting of two mating halves containing a plurality of wire contacts of equal geometric diameters, capable of accommodating component leads of differing geometric configurations (i.e., square, rectangular, triangular, round, etc.) which provide pressure to the component lead thereby holding the component in place. The insert is unaffected by the molten solder or flux used during the manufacturing process and prevents entry of contaminating material into the interior of the socket assembly during the soldering process thereby eliminating electrical shorting problems occasionally caused by the soldering process. The insert is surrounded by a U-shaped bracket which acts as a retainer spring on the insert to the socket assembly and is held in place by protrusions extending from the insert which mate with slots in the U-shaped bracket. The socket assembly is inserted into the printed circuit board and is removable from such printed circuit board prior to the soldering process.

摘要： A method and an apparatus provide a surface mountable package (100) with leads (150) having free end portions (355) coplanar in a target plane (370). The method includes forming the leads (150) such that the free end portions (355) angle away from the target plane (370), and biasing the free end portions (355) against a biasing surface (365) integral to the package (100) such that the free end portions (355) are forced toward the target plane (370) and into a coplanar state. The apparatus includes a housing (110), a plurality of leads (150) with free end portions (355) preformed to angle away from the target plane (370) mounted onto the housing (110), and a biasing surface (365), located on the package (100), to bias the free end portions (355) toward the target plane (370).

摘要： An expandable chassis includes a four sided frame with a central opening to receive a plate or "shield" which is allowed to move within the frame between two predetermined positions. Protuberances on the shield contact the frame and limit its inward movement while outward movement is limited by a spring clip on the shield that snaps into an aperture in the frame. Tabs on the frame support integrally formed spring fingers on the shield which tend to force the shield outward. A membrane switch contact assembly and a speaker are respectively attached to the inside and outside surfaces of the shield. By compressing the shield partially into the frame, the chassis assembly slides into a molded plastic housing. A rubber key actuator pad on the outside of the housing has a plurality of keys each having a protrusion or "actuator" that extends partially into an actuator hole in the housing. When the key is depressed, the actuator depresses and activates one of the switches in the membrane switch contact assembly. A plurality of speaker apertures extend through the housing, the membrane switch contact assembly, and the plate. An acoustic seal is formed between the plate and the housing because the spring fingers force the shield towards the housing until the membrane contacts the housing's inner wall. When the chassis is removed from the housing, testing and repair are facilitated because the keypad switches and speaker remain attached to and electrically connected to the chassis.
摘要翻译： 可扩展底盘包括具有中心开口以接收板或“屏蔽”的四边框架，该屏蔽件允许在框架内在两个预定位置之间移动。 屏蔽上的突起接触框架并限制其向内的运动，而向外的运动受到屏蔽上的卡扣入框架中的孔的弹簧夹限制。 框架上的突片支撑在屏蔽上的一体形成的弹簧指，其倾向于迫使屏蔽件向外。 膜开关接触组件和扬声器分别连接到屏蔽的内表面和外表面。 通过将屏蔽部分压缩到框架中，底盘组件滑入模制塑料外壳中。 壳体外侧的橡胶按键致动器垫具有多个键，每个键具有部分地延伸到壳体中的致动器孔中的突起或“致动器”。 当按下键时，执行器按下并激活薄膜开关触点组件中的一个开关。 多个扬声器孔径延伸穿过壳体，膜开关接触组件和板。 在板和壳体之间形成声学密封，因为弹簧手指将屏蔽件推向壳体，直到膜接触壳体的内壁。 当底盘从外壳中取出时，由于键盘开关和扬声器保持连接到机箱并与之电气连接，便于测试和维修。

摘要： One specially designed fixture allows two components such as a microprocessor and its associated ROM to be simultaneously mounted on opposite surfaces of the substrate, with all or nearly all internal connections made through the area of the substrate between the components. A second fixture allows for wave soldering lead frames to the assembly while protecting the reflow soldered components. The method thus provides the most direct connections between the two components with all internal connections and external connections made by two automatic operations. A third component can be positioned astraddle the mounted assembly for minimum lead lengths.
