Abstract:
Die Erfindung bezieht sich auf eine Rückwandleiterplatte (2) mit mehreren parallel nebeneinander auf der den Baugruppen zugewandten Seite (4) angeordneten Federleisten (6) und mit wenigstens einem Bus (30, 32), der wenigstens aus einer Busleitung (34, 36) besteht. Erfindungsgemäß ist einem Buskontaktstift (12, 14) jeder Federleiste (6) eines Busses (30, 32) ein federnder Kontakt (16, 18) auf der den Baugruppen abgewandten Seite (10) der Rückwandleiterplatte (2) angebracht, wobei jeweils der dem Buskontaktstift (12, 14) jeder Federleiste (6) benachbarte Kontaktstift (22, 20) des federnden Kontaktes (16, 18) elektrisch leitend mit dem zugeordneten Buskontaktstift (12, 14) verbunden ist, sind der zweite Kontaktstift (20, 22) jedes federnden Kontaktes (16, 18) mittels der Busleitung (34, 36) miteinander elektrisch leitend verbunden und ist die Kontaktierung jedes federnden Kontaktes (16, 18) mittels eines Handhabungsmittels (24) steuerbar ist. Somit können Baugruppen von einem baugruppenübergreifenden Bus (30, 32) abgetrennt werden, ohne dabei diese Baugruppen aus ihren Steckplätzen eines Baugruppenträgers herausziehen zu müssen.
Abstract:
A dual printed circuit board module having two printed circuit boards mounted in an inwardly facing relationship on two thermal frame members that also function as structural and enclosing members. A connector mounted between and at one edge of the thermal frame members serves to establish electrical connections between the circuit boards and a backplane circuit panel to which the boards are to be connected. A flexible interconnect circuit, located near the same edge of the boards as the backplane connector, is used both to connect the boards to the connector and to provide board- to-board connections independently of the connector. This arrangement greatly facilitates assembly and testing of the module, reduces signal path lengths, and enhances the structural and thermal integrity of the module.
Abstract:
A backplane power distribution system for making connections to the power planes of a computer system and having the capability of handling very high levels of current. This is achieved with a stepped backplane construction (17b-e). For example, in a multiple layer system having, in order, a first conductive layer (10a), a first dielectric layer (12a, 12b), a second conductive layer (10b), a second dielectric layer (12bc), and so on, each successive conductive and dielectric layers extend transversely beyond the preceding layers to present a substantial exposed area on all but the first conductive layer (17b-e). Typically, rectangular metal bus bars (not shown) are bolted to the backplane using plated through holes (20b-e) to make contact with the exposed areas (17b-e). Holes through the layers are provided and prepared such that each hole (15, 20 and 22) may make contact with a particular conductive layer as desired or in the case of ground with all ground conductive layers. Conductive layers (10a) and (10i) may be used as signal layers utilizing traces (14) and holes (15) while layers (10b-h) are so-called power planes.

Abstract:
Système de distribution d'alimentation par arrière-plan permettant d'établir des connexions entre les plans d'alimentation d'un système d'ordinateur et pouvant supporter des courants de niveau très élevé. Ceci est obtenu grâce à une construction d'arrière-plans en échelon (17b-e). Par exemple, dans un système multicouches possédant, dans l'ordre, une première couche conductrice (10a), une première couche diélectrique (12ab), une deuxième couche conductrice (10b), une deuxième couche diélectrique (12bc, etc.), chacune des couches conductrices et diélectriques successives s'étend transversalement au-delà des couches précédentes pour présenter une zone exposée considérable sur toutes les couches conductrices à l'exception de la première (17b-e). Généralement, des barres de bus métalliques rectangulaires (non illustrées) sont boulonnées aux arrière-plans en utilisant des trous traversants plaqués (20b-e) afin d'établir le contact avec les zones exposées (17b-e). Les trous traversant les couches sont obtenus et préparés de manière que chaque trou (15, 20 et 22) soit en contact avec une couche conductrice particulière désirée ou dans le cas d'une mise à la terre avec toutes les couches conduisant à la terre. Les couches conductrices (10a et 10i) peuvent être utilisées comme couches de signaux utilisant des tracés (14) et des trous (15) tandis que les couches (10b-h) sont appelées plans d'alimentation.
Abstract:
The present invention is applicable to the field of communications technologies, and provides a perpendicular and orthogonal interconnection system and a communications device. The perpendicular and orthogonal interconnection system includes a first board group, a second board group orthogonal to the first board group, and a center backplane arranged between the first board group and the second board group, where the first board group includes a plurality of first boards parallel to each other, and the second board group includes a plurality of second boards parallel to each other; a plurality of curved male connectors is arranged on each of the first boards, a plurality of curved female connectors is arranged on each of the second boards, and the curved male connectors and the curved female connectors directly cooperate and are connected in one-to-one correspondence. In the present invention, the curved male connectors and the curved female connectors directly cooperate and are connected. When the perpendicular and orthogonal interconnection system is upgraded, only the board that permanently has the curved male connectors and the curved female connectors needs to be replaced, which is rather simple and shortens a signal link. Based on the foregoing advantages, the perpendicular and orthogonal interconnection system is applicable to various communications devices; therefore, its upgrade is convenient, signal quality is improved, heat dissipation is ideal, and material costs are saved.
