    Abstract: A retainer for removable components that plug into a printed circuit board retains the removable component in an associated sockets on a printed circuit board. The retainer has the form of a clip including a retaining surface that applies a retaining force to the component. The retaining force is largely a spring force that directs the leads into the associated sockets by applying pressure to the top of the component. The retainer further has a positioning surface that positions the retaining surface in association with the component. This is done by the positioning surface engaging the exposed exterior surface of the associated sockets. A connecting surface connects the retaining surface to the positioning surface around the circuit board. In the preferred embodiment, the component is a crystal oscillator that plugs into the printed circuit board. Such crystal oscillators are removable to permit changing the operating frequency of an associated microwave transmission circuit.

    Abstract: Radio frequency emissions within a computer system having a printed circuit assembly in proximity of a metal surface are reduced by the placement of one or more lossy components electrically connected to a metal plane within the printed circuit assembly. A connector electrically connects the lossy components to the metal surface. In one embodiment, the lossy components include two resistors at opposite ends of an edge of the printed circuit assembly that is closest to the metal surface. In an alternate embodiment, a single lossy component is a resistor placed in the middle of an edge of the printed circuit assembly that is closest to the metal surface. In the alternate embodiment, a second connector at a first end of the edge of the printed circuit assembly that is closest to the metal surface directly connects the metal plane to the metal surface, and a third connector at a second end of the edge of the printed circuit assembly that is closest to the metal surface directly connects the metal plane to the metal surface. A spring is used to connect the printed circuit assembly to the metal surface. Ends of the spring are inserted into vias within the printed circuit assembly. Traces on the printed circuit assembly electrically connect the vias to the lossy component. Similarly, the vias may be directly connected to a ground or power plane without an intervening lossy component.

    Abstract: A connector (10) having one or more arrays of elongate arms (22) of contacts (20) having contact sections (26) on free ends (24) thereof to be soldered to respective traces (94) of a circuit element (90), facilitated by securing a soldering component (40) to free ends (24). Component (40) includes a block member (42) along the outer surface of which is secured a lead frame (60) which includes a corresponding plurality of fingers (66) extending transversely from an elongate body section (62). Block (42) is of thermally insulative material having solder resistive surfaces. On the finger ends (68) are affixed preforms (88) of solder; on body section (62) is defined a thin magnetic layer, transforming the brass carrier strip into a Curie point heater. When the body section is subjected to RF current, it generates thermal energy which melts the solder preforms to join the fingers first to the contact sections (26) of the connector contacts (20), and at a remote site later subjected to RF current to reflow the solder preform (88) to join contact sections (26) to traces (94). Block (42) is then removed along the body section (62) and portions of figures (66), defining discrete electrical connections at the solder joints.

    Abstract: An interchangeable adapter module allows a circuit board, tape cartridge system, or other add-on device to be readily interfaced with any of a variety of different computer systems. A number of pins extend perpendicularly outward from the device circuit board. An adapter circuit board having a pin connector attached thereto engages these pins to removably secure the adapter module in a plane parallel to the device circuit board. One or more external connectors attached to the adapter circuit board are then plugged into corresponding connectors of the external electronic system. Electrical interface circuitry on the adapter circuit board provides electrical interconnections between a predetermined set of the pins attached to the device, and a predetermined set of the electrical contacts of the external connectors.
