Description
dem die Signalleuchte 2 angeordnet ist Zur Montage ist die Leiterplatte 9 so in das Gehäuseunterteil 5 gemäß F i g. 4 einzulegen, daß dieser Quersteg 12 in die beiden Schlitze 13 in die Fassung 7 zu liegen kommt. Weitere nicht dargestellte Rastmittel halten dann die Leiterplatve 9 in dem Gehäuseunterteil 5 in ihrer richtigen Lage fest.which the signal light 2 is arranged for assembly the circuit board 9 so in the lower housing part 5 according to FIG. 4 insert that this crosspiece 12 in the two Slits 13 come to rest in the version 7. Further latching means, not shown, then hold the circuit board 9 in the lower housing part 5 in their correct position.
Auf beiden Seiten der Leiterplatte 9 sind zwei Bohrungen 14 nahe dem Leiterplattenrand und dicht beeinander vorgesehen, wodurch drei Engstellen 15, 16 entstehen. Ober diese sind auf der Unterseite der Leiterplatte 9 jeweils eine elektrische Leiterbahn 17 geführt, wie durch Strichelung angedeutet ist. Beim Herausziehen der Engstelle 16 zwischen den beiden Bohrungen 14 werden wegen der Sprödigkeit des für die Leiterplatte 9 verwendeten Materials, nämlich das unter seinem Handelsnamen bekannten Epoxid-Hartpapier, auch die Engstellen 15 herausgesprengt, so daß in einem Arbeitsgang drei Leiterbahnen 17 unterbrochen werden können. Dies ist auf der rechten Seite der Leiterplatte 9 durch die Heraustrennung 18 angedeutet. Durch die beiden Schlitze 13 ist die Fassung 7 gespalten und deshalb könnte die Schutzkappe 1 aus dem Gewinde herausrutschen. Die Versteifungsstege 8 geben als Widerlager der Fassung 7 größeren Halt.On both sides of the circuit board 9 there are two bores 14 near the edge of the circuit board and close to one another provided, whereby three bottlenecks 15, 16 arise. An electrical conductor track 17 is guided above these on the underside of the circuit board 9, as indicated by dashed lines. When pulling out the constriction 16 between the two bores 14 are because of the brittleness of the material used for the circuit board 9, namely that under its trade name known epoxy hard paper, also the constrictions 15 blown out, so that in one operation three conductor tracks 17 can be interrupted. This is on the right side of the circuit board 9 through the separation 18 indicated. The socket 7 is split by the two slots 13 and therefore the protective cap 1 could slip out of the thread. The stiffening webs 8 give as an abutment Version 7 greater hold.
