Abstract:
A circuit board comprises a carrier board which functions as a base structure to which is attached rigidly at least one electronics components card to form a wafer assembly where edge connectors to the components card are free for access, said card being attached to the carrier board by at least two rigid mechanical connectors for example glued plastic fasteners/screws or bolts, nuts and spacer means to maintain the carrier board and card at a selected separation.
Abstract:
Interlayer connections (3) for internal signal paths of the printed circuit board (1) are combined in groups and preferably situated in the shielding zone of shielded connectors for shielding cable to be plugged in. This arrangement insulates the interlayer connections (3) against high frequencies.
Abstract:
A control device such as a numerical controller constituted of a plurality of printed boards on which are mounted various circuit components. Input/output interface connectors (9) are mounted on the printed board (1) in a manner that the lengthwise directions thereof are oriented in the vertical direction relative to the mounting surface of the printed board. Module boards (10) are mounted in the vertical direction relative to the mounting surface of the printed board (1). The module boards (10) have a height nearly equal to the height of the interface connectors (9). This makes it possible to increase the number of circuit components that can be mounted in a unit space, and to decrease the outer size of the whole control device.
Abstract:
Die Erfindung betrifft einen Baugruppenträgerfür einseitig bestückte Flachbaugruppen (1) in Planaranordnung auf einer Verdrahtungsplatte (4), Sie gibt eine Potentialzuführung an, die einfach montierbar ist und die eine Zentrierung bzw. Fürung der Flachbaugruppen (1) bezüglich ihrer Steckverbinder (2, 2') gewährleistet. Erfindungsgemäß ist ein elektrisch leitender Gitterrahmen (5), dessen Zwischenräume als formschlüssige Einsteckkammern für die Flachbaugruppen (1) dienen, auf der Verdrahtungsplatte (4) befestigt. Der Gitterrahmen (5) besteht vorzugsweise aus galvanisch voneinander getrennten, mit Querstegen (11) versehenen Längsschienen (6), die jeweils mit unterschiedlichen Spannungspotentialen beaufschlagt und mit den Potentialflächen der Verdrahtungsplatte (4) leitend verbunden sind.
Abstract:
A backplane and a communications device are disclosed. The backplane includes: at least one fixing plate (200), multiple connectors (300), and multiple flexible cables (400), where signal connection is implemented between corresponding connectors (300) by means of the flexible cables (400), each of the connectors (300) is provided with a housing (301) and multiple signal pins (302) installed on the housing (301), and the housing (301) is installed on the fixing plate (200) and is provided with a jack for insertion of a connector of a subcard in the communications device; one end of each signal pin (302) is inserted into the jack, and the other end is connected to each flexible cable (400); and a surface of the fixing plate (200) facing the subcard in the communications device is an insertion surface, and the multiple flexible cables (400) are located on a side of the fixing plate opposite to the insertion surface. When the communications device provided with the backplane transmits a high-rate signal, transmission quality and a transmission rate are relatively high.
