Abstract

A connection of two metal sheets (1, 5) is published, which rest one on top of the other and are electrically insulated from one another by means of at least one coating (2). The metal sheets (1, 5) are connected to one another by means of at least two sheet-metal screws, two thread-cutting screws or two self-tapping screws (4), the screws (4) in each case being screwed in through a penetrating hole (3) in the one metal sheet (1) into a hole (6) which is provided in the other metal sheet (5) and is matched to the type of screw used. In order to produce an electrically conductive connection between the two metal sheets (1, 5) there is such a difference between the distance between the adjacent penetrating holes (3) in the one metal sheet (1) in comparison with the distance between the holes (6) in the other metal sheet (5) that the screws (4) touch the walls of the penetrating holes (3) of the one metal sheet (1) on the inside metallically. <IMAGE>

Description

Verbindung zweier aufeinander liegender, durchConnection of two superimposed, through

mindestens einen Belag elektrisch gegeneinander isolierter Bleche Die Erfindung bezieht sich auf eine Verbindung zweier aufeinander liegender, durch mindestens einen Belag elektrisch gegeneinander isolierter Bleche nach dem Oberbegriff des Patentanspruches.at least one covering of metal sheets that are electrically insulated from one another The invention relates to a connection between two superposed, by at least one covering of metal sheets electrically insulated from one another according to the preamble of the claim.

Es ist bekannt, bei elektrischen Einrichtungen, zum Beispiel zur Bildung von Gehäusewänden, zwei auf ein anderliegende Bleche durch Schrauben miteinander zu verbinden.It is known in electrical equipment, for example for education of housing walls, two sheets lying on top of one another by screws together connect to.

Als Schrauben werden hierbei vornehmlich Blechschrauben, Gewinde-furchende Schrauben oder selbstschneidende Schrauben verwendet, die durch ein Durchgangsloch des einen Bleches in ein Loch des anderen Bleches eingeschraubt sind.The screws used here are primarily sheet metal screws, thread-forming screws Screws or self-tapping screws are used that go through a through hole of one sheet are screwed into a hole in the other sheet.

Ein Farbauftrag, eine Pulverbeschichtung oder ein sonstiger elektrisch isolierender Belag auf mindestens einem der Bleche kann eine zum Beispiel zu Erdungszwecken erforderliche elektrisch leitfähige Verbindung der Bleche untereinander verhindern.A paint application, a powder coating or any other electrical An insulating coating on at least one of the sheets can, for example, be used for grounding purposes prevent the necessary electrically conductive connection between the sheets.

Aufgabe der Erfindung ist es, die Verbindung der im Oberbegriff des Patentanspruches genannten Art so auszubilden, daß zwischen den mechanisch miteinander verbundenen Blechen auf einfache Weise auch eine elektrisch leitfähige Verbindung gegeben ist.The object of the invention is to provide the compound in the preamble of To train said type so that between the mechanically each other connected sheets in a simple manner also an electrically conductive connection given is.

Die gestellte Aufgabe wird erfindungsgemäß, wie im kennzeichnenden Teil des Patentanspruches angegeben, gelöst.The object is set according to the invention, as in the characterizing Part of the claim specified, solved.

Die gefundene Lösung hat den Vorteil, daß zu ihrer Verwirklichung nur die ohnehin vorhandenen Verbindungsmittel erforderlich sind und nur das ohnehin notwendige Eindrehen der Schrauben vorzunehmen ist.The solution found has the advantage that it can be implemented only the already existing lanyards are required and only that anyway necessary screwing in of the screws is to be carried out.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung beispielsweise und rein schematisch dargestellt. Die Zeichnung zeigt im Schnitt eine Seitenansicht zweier aufeinanderliegender Bleche.An embodiment of the invention is shown in the drawing, for example and shown purely schematically. The drawing shows a sectional side view two sheets lying on top of one another.

In der Zeichnung ist mit 1 ein Blech bezeichnet, das auf beiden Seiten mit einem elektrisch isolierenden Belag 2 versehen ist. Der Belag 2 kann durch einen Farbanstrich, durch Pulverbeschichtung oder auf andere Weise gebildet sein.In the drawing, 1 denotes a sheet metal on both sides is provided with an electrically insulating covering 2. The covering 2 can by a Paint, powder-coated or otherwise.

Im Blech 1 sind mindestens zwei Durchgangslöcher 3 für Blechschrauben, Gewinde-furchende Schrauben oder selbstschneidende Schrauben 4 vorgesehen.In sheet metal 1 there are at least two through holes 3 for self-tapping screws, Thread-rolling screws or self-tapping screws 4 are provided.

Das Blech 1 liegt auf einem Blech 5 auf, das in nicht dargestellter Weise auf einer Seite oder auf beiden Seiten mit einem ähnlichen Belag wie das Blech 1 versehen, oder auch blank oder galvanisch beschichtet sein kann.The sheet 1 rests on a sheet 5, which is not shown in Way on one side or on both sides with a similar covering as the sheet metal 1, or can be blank or electroplated.

Maßgebend für die Anordnung ist, daß eines der beiden Bleche 1,5 einen Belag aufweist, der die Bleche 1,5 gegeneinander elektrisch isoliert.It is crucial for the arrangement that one of the two sheets 1.5 a Has coating that electrically isolates the sheets 1.5 from one another.

Im Blech 5 sind den Durchgangslöchern 3 des Bleches 1 zugeordnete Löcher 6 vorgesehen, deren Durchmesser jeweils auf die verwendete Schraubenart abgestimmt ist.In the sheet 5, the through holes 3 of the sheet 1 are assigned Holes 6 provided, their diameter each to the used Type of screw is matched.

Zwischen den Abständen der Durchgangslöcher 3 des einen Bleches 1 und den Löchern 6 des anderen Bleches 5 besteht ein solcher Unterschied, daß die Schrauben 4 die Wände der Durchgangslöcher 3 sehr stark metallisch berühren.Between the distances between the through holes 3 of one sheet 1 and the holes 6 of the other sheet 5 is such a difference that the Screws 4 touch the walls of the through holes 3 very strongly metallic.

Durch die infolge der Abstandsdifferenz zwischen den Löchern 3 und 6 der Bleche 1 und 5 sich zwingend ergebende Berührung der Schrauben 4 mit den Wänden der Durchgangslöcher 3 und die ohnehin beim Eindrehen der Schrauben 4 in die Löcher 6 entstehende metallische Berührung der Schrauben 4 mit dem Blech 5 ist eine zum Beispiel für eine Erdung geeignete galvanische Verbindung zwischen den Blechen 1,5 gegeben, so daß auf andere Maßnahmen zum Herstellen einer elektrisch leitfähigen Verbindung zwischen den Blechen 1,5 verzichtet werden kann.Due to the difference in distance between the holes 3 and 6 of the sheets 1 and 5, the screw 4 must come into contact with the walls the through holes 3 and anyway when screwing the screws 4 into the holes 6 resulting metallic contact of the screws 4 with the sheet 5 is a for Example of a suitable electrical connection between the metal sheets 1.5 given, so that on other measures to produce an electrically conductive Connection between the sheets 1.5 can be dispensed with.

Bei dem Zusammenschrauben der Bleche 1,5 wird zweckmäßig so vorgegangen, daß beide Schrauben 4 zunächst erst etwa halb und dann erst nacheinander vollständig in das Blech 5 eingedreht werden. In der etwa halb eingedrehten Stellung der Schrauben 4, sind die Bleche 1,5 verschiebungsfrei gegeneinander festgelegt. Bei dem weiteren Eindrehen der Schrauben 4 werden die Bleche 1,5 gegeneinander verspannt, wobei sich die Schrauben 4 einseitig in die Wände der ihnen zugeordneten Durchgangslöcher 3 eingraben und so die elektrisch leitfähige Verbindung sicherstellen.When screwing the sheets 1.5 together, it is advisable to proceed as follows: that both screws 4 initially only about half and then completely one after the other be screwed into the sheet 5. In the approximately half-screwed position of the screws 4, the sheets 1.5 are fixed relative to one another without displacement. With the other Screwing in the screws 4, the sheets 1.5 are braced against each other, with the screws 4 on one side in the walls of the through holes 3 assigned to them dig in and thus ensure the electrically conductive connection.

Wenn mehrere Schrauben 4 vorgesehen sind, kann es genügen, die Abstände von zwei benachbarten Durch- gangslöchern 3 des einen Bleches 1 und die Abstände der zugeordneten Löcher des anderen Bleches 5, wie angegeben, zu bemessen. Zur Erhöhung der Zahl der elektrisch leitfähigen Stellen zwischen den Blechen 1 und 5 können jedoch auch die Abstände mehrerer oder aller Durchgangslöcherpaare des einen Bleches 1 und die Abstände der zugeordneten Löcherpaare des anderen Bleches 5 entsprechend bemessen werden.If several screws 4 are provided, it may be sufficient to adjust the distances from two neighboring passage holes 3 of one sheet 1 and the distances between the associated holes of the other sheet 5, as indicated, to measured. To increase the number of electrically conductive points between the Sheets 1 and 5 can, however, also have the spacing between several or all pairs of through holes of one sheet 1 and the distances between the associated pairs of holes in the other sheet 5 must be dimensioned accordingly.
