Abschirmgehäuse fur Steckeinschube der elektrischen Nachrichtentechnik Shielding housing for plug-in units in electrical communications technology
Die Neuerung bezieht sich auf ein Abschirmgehause für Steckeinschübe der elektrischen Nachrichtentechnik. Bei manchen derartigen Einschüben besteht eine erhöhte Storstrahlungsgefahr. Besonders gilt dies bei modernen Stromversorgungseinrichtungen der Nachrichtentechnik, die als Schaltregler mit Schaltfrequenzen = 20 kHz ausgeführt sind.The innovation relates to a shielding housing for plug-in units in electrical communications technology. Some of these units pose an increased risk of interference radiation. This is particularly true for modern power supply units in communications technology, which are designed as switching regulators with switching frequencies of 20 kHz.
Die Leistungsteile solcher Regler beeinträchtigen mit starken elektromagnetischen Störfeldern die elektrischen Eigenschaften benachbarter Geräte und durch ihre in Wärme umgesetzte Verlustleistung die Lebensdauer der Bauelemente.The power components of such controllers impair the electrical properties of neighboring devices with strong electromagnetic interference fields and the service life of the components due to the power loss converted into heat.
Der Neuerung liegt die Aufgabe zugrunde dagegen mit einfachen konstruktiven Mitteln Abhilfe zu schaffen.The aim of the innovation is to remedy this problem using simple constructive means.
Gemäß der Neuerung wird dies dadurch erreicht, daß das Gehäuse im Querschnitt betrachtet im Inneren zwei Längsnuten zum Einschieben von steckbaren Leiterplatten und außenseitig zuei Federn hat, die der Einschubführung in einem übergeordneten Gerät dienen, sowie am einen, den Steckanschlüssen gegenüberliegenden Ende abgeschlossen und dort mit Kühlrippen versehen ist und daß das Gehäuse einstückig insbesondere in Fließpreßtechnik ausgeführt ist.According to the innovation, this is achieved by the housing, viewed in cross-section, having two longitudinal grooves on the inside for inserting plug-in circuit boards and two springs on the outside that serve to guide the insert into a higher-level device, as well as being closed at one end opposite the plug connections and provided with cooling fins there, and by the housing being made in one piece, in particular using extrusion technology.
Nachstehend wird die Neuerung anhand des in der Figur dargestellten Ausführungsbeispieles näher erläutert.The innovation is explained in more detail below using the embodiment shown in the figure.
Die Erfindung sieht zur Aufnahme einer Störstrahlung und Wärme erzeugenden Baugruppe ein fließgepreßtes Gehäuse aus Leichtme-The invention provides an extruded housing made of light metal for accommodating an interference radiation and heat-generating assembly.

Das Gehäuse weist innen Längsnuten 2 zur Führung der nicht dargestellten Leiterplatte mit Steckverbindern und äußert als Federn ausgebildete Stege 3 zur Führung des Gehäuses in Schienen der Geräteeinsätze der Bauweise 7 R auf.The housing has longitudinal grooves 2 on the inside for guiding the printed circuit board (not shown) with connectors and on the outside webs 3 designed as springs for guiding the housing in rails of the device inserts of type 7 R.
Die Gehäusefront ist zur besseren GeräteentWarmung als Kühl-* köfper 4 geformt*The front of the housing is shaped like a heat sink 4 for better device heat dissipation*
Das Gehäuse kann auch aus im ganzen metallisierten Kunststoff hergestellt werden* Es wird so ein niederohmicjer und mit großer Frontoberfiäche ausgestatteter Gehäuseaufbau erreicht* Das Übergreifen der von der Schaltung erzeugten elektromagnetischen Störfelder wird verhindert und die Wärmeableitung aus dem Gehäuse durch die Rippenfrönt Verbessert.The housing can also be made from completely metallized plastic* This creates a low-resistance housing structure with a large front surface* The spread of the electromagnetic interference fields generated by the circuit is prevented and the heat dissipation from the housing is improved by the ribs.
Hierdurch ergibt sich ein störstrahlungsfreiei: Aufbau, sei es, daß das Gehäuse aus Aluminium oder einem metallierten kunststoff hergestellt ist.This results in a structure free from interference, whether the housing is made of aluminum or a metalized plastic.
