Gehäuse für Leiterplatten mit genormten Abmessungen und genormten Steckeroder BuchsenleistenHousing for printed circuit boards with standardized dimensions and standardized plug or socket strips
Die Erfindung betrifft ein Gehäuse für Leiterplatten mit genormten Abmessungen und genormten Stecker- und/oder Buchsenleisten, die vorzugsweise von einem sogenannten Kartenträger aufgenommen werden.The invention relates to a housing for printed circuit boards with standardized Dimensions and standardized plug and / or socket strips, which are preferably received by a so-called card carrier.
Bei genormten Leiterplatten, die in einen Kartenträger eingesetzt sind, tritt das Bedürfnis auf, die auf der Leiterplatte befindlichen Bauelemente und Lötstellen sowohl vor Berührung und unbefugtem Hantieren, als auch vor mechanischer und elektrischer Beschädigung zu schützen, in besonderem Maße gilt dies für Leiterplatten, die häufig gewechselt werden (z.B. Programme für Mikroprozessoren). Außerdem besteht oft die Notwendigkeit, Störstrahlung von außen nach innen - und umgekehrt - zu verhindern.For standardized printed circuit boards that are inserted into a card carrier there is a need to protect the components and soldering points on the circuit board from being touched and tampered with, as well as to protect against mechanical and electrical damage, this applies in particular to printed circuit boards, which are frequently changed (e.g. programs for microprocessors). In addition, there is often the need to radiate interference from the outside inside - and vice versa - to prevent.
Es sind Konstruktionen bekannt, die aus einem U-förmig gebogenen Blech oder aus einer Metallplatte bestehen, und mittels Distanzbolzen an der Leiterplatte befestigt sind. Diese Konstruktionen dienen jedoch meist nur zur Abführung entstehender Verlustwärme (Kühlblech). Derartige Ausführungen sind aber auf den speziellen Anwendungsfall zugeschnitten und daher nicht universell verwendbar.There are known constructions that consist of a U-shaped bent sheet metal or consist of a metal plate and are attached to the circuit board by means of spacer bolts. However, these constructions are mostly used only for the dissipation of waste heat (cooling plate). Such designs are tailored to the specific application and therefore not universally applicable.
Außerdem umschließen sie nicht vollständig Bestückungs- und Lötflächen der Leiterplatten.In addition, they do not completely enclose the mounting and soldering areas of the circuit boards.
Der Erfindung liegt das Ziel zugrunde, ein billig herstellbares, universell verwendbares, geschlossenes Gehäuse für Leiterplatten mit genormten Abmessungen und genormten Stecker- oder Buchsenleisten, insbesondere für die weitverbreitete sogenannte Europakarte zu schaffen, das weder die AufnahmeThe invention is based on the goal of a cheap, universal Usable, closed housing for printed circuit boards with standardized dimensions and standardized plug or socket strips, in particular for the widespread so-called Eurocard, to create neither the recording

der Leiterplatte in einen Kartenträger verhindert, noch eine wesentliche Einbuße der Leiterplatten-Nutzfläche verursacht. Dieses Ziel wird durch ein geschlossenes Kunststoff-Gehäuse erreicht, das j aus einem Ober (2)- und/oder Unterteil (3) besteht, und das die Löt- und/ oder Bestückungsflächen der Leiterplatte (1) nur soweit umschließt, daß die zur Führung in einem Kartenträger notwendige Leiterplattenfläche nicht bedeckt wi rd.The circuit board in a card carrier prevents yet another essential Caused loss of the usable area of the printed circuit board. This goal is achieved by a closed plastic housing, which consists of an upper (2) and / or lower part (3), and which contains the soldering and / or mounting surfaces of the circuit board (1) encloses only to the extent that the circuit board surface required for guidance in a card carrier is not covered
Eine Abschirmung gegen Störstrahlung kann einfacherweise durch metallisieren der Gehäuseoberflächen erreicht werden.A shield against interference radiation can simply be done by metallizing the housing surfaces can be achieved.
Ober (2)- und/oder Unterteil (3) können an der Leiterplatte (1) entweder durch Schrauben oder durch eine im Kunststoff eingearbeitete Einschnappoder Haltevorrichtung (4) (Haken o.a.) die in Bohrungen oder entsprechende Ausschnitte der Leiterplatte eingreifen, befestigt werden. Eine weitere Befestigungsmöglichkeit besteht auch darin, daß Ober (2)- und Unterteil (3) durch Schrauben oder durch eine im Kunststoff eingearbeitete Einschnapp- oder Haltevorrichtung (5) miteinander verbunden sind, und dadurch die Leiterplatte zwischen Ober- und Unterteil geklemmt ist. Ebenfalls besteht die Möglichkeit, eine oder mehrere Plomben anzubringen, so daß ein unbefugtes öffnen des Gehäuses erkennbar wird.Upper (2) and / or lower part (3) can either be attached to the circuit board (1) by screws or by a snap-in or built into the plastic Holding device (4) (hook or similar) in holes or corresponding Engage cutouts of the circuit board, are attached. Another possibility of attachment is that upper (2) - and Lower part (3) by screws or by one incorporated in the plastic Snapping or holding device (5) are connected to one another, and thereby the circuit board is clamped between the upper and lower part. It is also possible to attach one or more seals, see above that unauthorized opening of the housing is recognizable.
