Abstract:
The invention relates to a fitted and soldered printed circuit board (1) of a flat assembly on which an additional component (2) is subsequently added and soldered. The printed circuit board has two solder-free fixing holes (7, 8) to fix the ends of the leads (4, 5) of the additional component (2), between which two interspaced soldering pads (10, 11) are placed, enabling said additional component (2) to be fixed onto the printed circuit board (1) and to be electrically connected. The leads (4, 5) have an area (12) running parallel to the surface of the printed circuit board (3) and a second area (14) running perpendicular to said surface, which are inserted into both fixing holes (7, 8).
Abstract:
A built-on control device has a multi-part casing (16) open on one side which is fitted to the casing block (10) of a hydraulic assembly. A printed circuit board (29) for an electronic circuit with several electronic components (33) is fitted in the casing (16) of the built-on control device (15). The printed circuit board (29) consists of a plurality of rigid regions (30, 25), in which one rigid region is formed by the cover (25) of the casing (16). Between the two rigid regions (25, 30) there is a looped, flexible region (36) consisting only of the conductor foil (31). In addition, the conductor foil (31) projects beyond the rigid region (30) of the printed circuit board (29) and is contacted in this region (28) by the terminal pins (27) of the consumer (12) of the hydraulic assembly. Since direct contact with the conductor foil (31) is provided in the flexible region of the printed circuit board (29), tolerances can easily be compensated, this permitting easy contacting and thus a simple production of the built-on control device on the casing block (10).

Abstract:
The invention relates to a module (1) comprising a housing (2), a printed circuit board (3) and a separate electronic component (4) which has a number of electric connections (5), characterized in that the or each connection (5) of the component (4) is electrically connected to a conductor track of the printed circuit board (3) by means of a blade contact (25), the component (4) being fixed in the housing (2) by means of a number of elastic bearing elements (18). The component (4) is thus easily and securely fixed. Rattling noises are avoided.
Abstract:
The present invention relates to a flat-type connector clamp, a printed circuit board (PCB) including the flat-type connector clamp and a method of manufacturing the same, wherein the connector clamp is formed on the surface of the PCB without being protruded from the surface of the PCB or the connector clamp is formed to function as a single component or element. The PCB for mounting a component or element therein includes one or more flat-type connector clamps, each connector clamp drilled in the PCB to have a pressing part and coated with a conductive material, the connector clamp being configured to be in contact with a leg of the inserted component or element while pressing the leg toward a center of the connector clamp to perform signal transmission. The connector clamp includes a clamp hole, pressing pieces, the pressing pieces, auxiliary holes and a connector lead. Thus, the connector clamp can be firmer and more convenient to be used, thereby reducing contact resistance due to insertion and increasing conductivity. Also, it is possible to reduce the unit cost and the period of production and decrease the weight of the PCB by overcoming the problems in a conventional PCB production.
Abstract:
The present invention is directed to current mode output control with a current mode (CM) region of the high voltage output curve (VI) slope controlled by component selection and arrangement in the construction of high voltage power supplies. The controlled CM current slope output, the tapped multiplier feedback network, and the subsequent output voltage correction network, yields a power supply with the desired VM and CM output characteristics that is significantly less expensive to construct and more efficient than a power supply built using conventional construction techniques.
Abstract:
A process relating to a one step low pressure injection molding method of encapsulating high voltage circuitry while incorporating a unique recessed high voltage connector contact means within the injection molding material, greatly reducing the component size, while increasing the capabilities of this type of circuitry. The process reduces the manufacturing time and maintains a clean sealed contact point for repeated usage by the means of a conductive rubber slug. An additional advantage is by creating cavities through the circuit board; axially leaded high voltage components may be conveniently mounted without additional assembly components while being fully encapsulated.
