Abstract:
Die Erfindung betrifft eine Leiterbahneinheit insbesondere für ein Kraftfahrzeug. Die Leiterbahneinheit ist mit in einem elektrisch isolierenden Material eingebetteten Leiterbahnen versehen. Die Leiterbahnen sind insbesondere vollständig vom elektrisch isolierenden Material umgeben und sind daher nicht von außen zugänglich. Elektrische Anschlüsse sind mit den Leiterbahnen elektrisch verbunden. Die elektrischen Anschlüsse sind von außen zugänglich, so dass diese mit elektrischen Kontakten von elektrischen oder elektronischen Bauteilen wie Schalter, Detektor, elektronisches Funkbauteil, integrierter Schaltkreis, elektronischer Chip, elektronische Steuereinrichtung oder Motor beispielsweise durch Löten elektrisch verbunden werden können. Die Leiterbahnen und elektrischen Anschlüsse sind verschiedene Bauteile, die also zunächst voneinander unabhängig sind und voneinander unabhängig hergestellt werden können. Es kann so eine besonders robuste und dennoch filigrane Leiterbahneinheit bereitgestellt werden.
Abstract:
An electronic device includes a housing (120), a circuit board (100), a plurality of holders (180) having mechanical connectors to the housing (120) and to the circuit board (100) and mechanically fixing the circuit board (100) within the housing (120), and at least one capacitor (130) having a first electrode (131), a second electrode (132) and a dielectric arranged between the first and second electrodes (131, 132). The first electrode (131) is electrically connected to a contact (110) on the circuit board (100), and the second electrode (132) is electrically connected to the housing (120). The at least one capacitor (130) is part of one of the plurality of holders (180); and the dielectric of the capacitor (130) is part of a thermal insulation between the connectors to the circuit board (100) and to the housing (120).
Abstract:
A socket connector for connecting a bulbous terminal or ball wherein the female element grips the terminal with resilient prongs with end tips at low insertion force but positive contact is maintained and wherein attempted withdrawal is normally inhibited by increasing force applied to the post by the female element in response to the withdrawal force. The female element comprises a tube of resilient conductive material that has been sliced or helically partitioned into opposing prongs of a width that decreases with axial distance from the end of the connector so as to allow the prongs of the connector to grip around the ball-like bulbous terminal and mechanically retain the terminal within the connector. The tubular element of the connector may be made by forming prongs in one or both ends of a tube by cuts of a width that increases with distance from the end of the tube.
Abstract:
An assembly of at least two printed circuit boards includes an intermediate connection layer (40) for providing electrical and mechanical connections between first and second circuit boards (10,12). The intermediate connection layer comprises a lower set of connection pads connecting the intermediate layer to the first circuit board, and an upper set of connection pads connecting the intermediate layer to the second circuit board. The intermediate connection layer comprises connection regions and a void region, wherein the void region extends between the first and second circuit boards and houses electronic components (16) of the circuit boards. This arrangement uses an intermediate connection layer to provide a stable mechanical connection, provide electrical connections between the circuit boards, and define a spacing for housing the electrical components of one or both of the circuit boards. The connections can be soldered, and this can be performed by reflow soldering methods, and using pick and place equipment.
Abstract:
An apparatus includes a printed circuit board (PCB) (200, 200a-200m, 705) including a surface (205) that has a layer of circuitry (215, 220, 225, 230, 235, 240, 245, 250, 255, 260, 265, 709, 710). The apparatus also includes a heat sink (300) configured to receive heat from the PCB. The apparatus further includes a thermally- conductive post (400, 500, 707) configured to remove the heat from the PCB to the heat sink via thermal conduction through a thermal path. The thermal path is substantially orthogonal to the surface of the PCB. The post includes an end configured to physically couple to the layer of circuitry.
