Abstract
Hochfrequenzdichtes Kastengehäuse für elektronische Geräte mit einem mindestens an einem Ende offenen Blechtubus (1), dadurch gekennzeichnet, daß die Ränder des zum Tubus (1) gebogenen Bleches (2) durch schwalbenschanzförmig ineinandergreifende Verzahnungen (3, 4) miteinander formschlüssig verbunden sind, wobei die Zähne mit Übermaß in die Zahnlücken gepreßt und hochfrequenzdicht verpreßt sind.High-frequency-tight box housing for electronic devices with a tin tube (1) which is open at least at one end, characterized in that the edges of the sheet (2) bent to form the tube (1) are positively connected to one another by teeth (3, 4) which interlock with one another in a dovetail shape, the Excessive teeth are pressed into the tooth gaps and pressed in a high-frequency-tight manner.
Description
Die Erfindung betrifft ein hochfrequenzdichtes Kastengehäuse für elektronische Geräte mit einem mindestens an einem Ende offenen, aus einem Blech gebogenen Gehäusetubus laut Oberbegriff des Hauptanspruches, sowie ein Verfahren zum Herstellen eines solchen Gehäusetubus.The invention relates to a radio frequency-tight box case for electronic equipment with an open at least at one end, bent from a sheet Housing barrel according to the preamble of the main claim, as well as a method for manufacturing of such a housing tube.
Hochfrequenzdichte Kastengehäuse dieser Art
sind bekannt (
Es ist daher Aufgabe der Erfindung, ein hochfrequenzdichtes Kastengehäuse dieser Art zu schaffen, bei dem der hierbei benutzte Gehäusetubus auf einfache Weise in kürzester Zeit gegebenenfalls sogar aus vorlackiertem Blech herstellbar ist. Außerdem soll ein einfaches und billiges Herstellungsverfahren hierfür aufgezeigt werden.It is therefore an object of the invention to create a radio frequency-tight box housing of this type, where the housing tube used here easily in the shortest possible time Time may even be produced from pre-painted sheet metal. In addition, should demonstrated a simple and inexpensive manufacturing process for this become.
Diese Aufgabe wird ausgehend von einem Kastengehäuse laut Oberbegriff des Hauptanspruches durch dessen kennzeichnende Merkmale gelöst. Vorteilhafte Weiterbildungen insbesondere bezüglich eines besonders einfachen und billigen Herstellungsverfahrens ergeben sich aus den Unteransprüchen.This task is based on a box case according to the preamble of the main claim by its characteristic Features solved. Advantageous further developments, in particular with regard to a particularly simple one and cheap manufacturing process result from the subclaims.
Beim, erfindungsgemäßen Kastengehäuse werden
die Ränder
des Gehäusetubus
durch eine an sich bekannte Verzahnung formschlüssig miteinander verbunden
(Verzahnungstechnik beispielsweise nach
Durch anschließendes zusätzliches Verdichten der so hergestellten kaltverpreßten Verzahnungen wird die Verbindung der Blechränder auch für höchste Frequenzen hochfrequenzdicht und zwar auf der ganzen Länge der Randverbindung. Nachdem die Herstellung dieser Verzahnungen an den Rändern des zum Tubus gebogenen Bleches durch Stanzen, Laserschneiden oder Wasserstrahlschneiden herstellbar ist kann dies auch an einem vorlackierten Blechmaterial durchgeführt werden, wodurch die Herstellung eines solchen Gehäusetubus sehr preiswert wird.By subsequently compressing the so manufactured cold pressed Gears make the connection of the sheet metal edges high-frequency-tight even for the highest frequencies along the entire length the edge connection. After making these gears on the edges of the sheet metal bent to the tube by punching, laser cutting or Water jet cutting can also be done on a pre-coated sheet material carried out be, whereby the manufacture of such a housing tube becomes very inexpensive.
Die Erfindung wird im folgenden anhand schematischer Zeichnungen an einem Ausführungsbeispiel näher erläutert.The invention will now be described more schematically Drawings on an embodiment explained in more detail.
