Description

Die vorliegende Erfindung bezieht sich auf ein Signalleuchte deren Gehäuse frontseitig eine mit einer lichtdurchlässigen Platte abgedeckte Durchbrechung aufweist, hinter welcher Platte eine Leuchtdiode vorhanden ist, welche mit einem Vorwiderstand auf eine zur Gehäuselängsachse quer orientierte Leiterplatte montiert ist.The present invention relates to a signal lamp whose housing has an opening covered with a translucent plate on the front, behind which plate there is a light-emitting diode which is mounted with a series resistor on a printed circuit board oriented transversely to the longitudinal axis of the housing.

Derartige Signalleuchten sind bekannt und beispielsweise in den schweizerischen Patentgesuchen 6737/82 und 3194/83 beschrieben. Bei diesen Signalleuchten ist es jeweils erforderlich, in der Frontplatte der Montagewand eine der Grösse des Leuchtengehäuses entsprechende Durchbrechung anzubringen. In diese Durchbrechung wird das Leuchtengehäuse bis zum Verrasten eingeschoben, so dass nur ein äusserst dünner Frontrahmen sichtbar bleibt.Such signal lights are known and described, for example, in Swiss patent applications 6737/82 and 3194/83. With these signal lights, it is necessary to make an opening in the front panel of the mounting wall that corresponds to the size of the light housing. The luminaire housing is pushed into this opening until it clicks into place so that only an extremely thin front frame remains visible.

Die vorliegende Erfindung stellt sich die Aufgabe, eine Vorrichtung der eingangs erwähnten Art derart zu ändern, dass der Montageaufwand für die Leuchte wesentlich geringer wird.The present invention has for its object to change a device of the type mentioned in such a way that the assembly effort for the lamp is significantly less.

Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass die Seitenwand des Gehäuses geschlossen ist und rückseitig eine durchgehende Abschlusskante bildet, und dass auf der Gehäuserückseite Befestigungsmittel zur Befestigung des Gehäuses an einer Schalttafel vorhanden sind.According to the invention, this object is achieved in that the side wall of the housing is closed and forms a continuous terminating edge on the rear, and that fastening means for fastening the housing to a control panel are present on the rear of the housing.

Die Erfindung bewirkt, dass in die Frontplatte der Montagewand lediglich mittels einer Lehre Bohrungen für den Durchtritt der Anschlussleiter für die Leuchtdiode anzubringen sind. Nach einer bevorzugten Ausführungsform ist vorgesehen, dass das Gehäuse mit einer Rückwand eine zur Abschlusskante koplanare Ebene bildet, welche mit einer Selbstklebeschicht überzogen ist. Bei dieser Ausführungsform können Anschlussleiter durch die Bohrung hindurchgeschoben und die Leuchten auf die Frontplatte aufgeklebt werden. Die Signalleuchte kann in diesem Fall lediglich auf die Frontplatte einer Schalttafel aufgeklebt werden, was die Montage vereinfacht.The invention has the effect that holes for the passage of the connecting conductors for the light-emitting diode are to be drilled in the front plate of the mounting wall only by means of a teaching. According to a preferred embodiment, it is provided that the housing forms with a rear wall a plane which is coplanar with the end edge and which is covered with a self-adhesive layer. In this embodiment, connecting conductors can be pushed through the bore and the lights can be glued to the front panel. In this case, the signal lamp can only be glued to the front panel of a control panel, which simplifies assembly.

Ist vorgesehen, dass das Gehäuse eine Rückwand aufweist, an der wenigstens ein zur Gehäuselängsachse paralleler Gewindebolzen befestigt ist durch den achsparallel die Anschlussleitungen für die Leuchtdiode geführt sind, so kann das Leuchtengehäuse dadurch an der Frontplatte befestigt werden, dass von der Rückseite der Frontplatte auf den Gewindebolzen eine Mutter aufgeschraubt wird. Ist die Rückseite zusätzlich mit einer Selbstklebeschicht versehen, wird die Signalleuchte zuerst aufgeklebt und dann von der Rückseite festgeschraubt. Dies ist besonders bei grossen Frontplatten von Vorteil, da die Montage von nur einer Person ausgeführt werden kann. Eine flache und kompakte Bauweise des Leuchtengehäuses wird dadurch erreicht, dass die Gehäuserückwand als Leiterplatte ausgebildet und darauf die Leuchtdiode befestigt ist.If it is provided that the housing has a rear wall, to which at least one threaded bolt is fastened, parallel to the longitudinal axis of the housing, through which the connecting lines for the light-emitting diode are guided parallel to the axis, the luminaire housing can be fastened to the front panel by moving from the rear of the front panel to the Threaded bolt a nut is screwed on. If the back is also provided with a self-adhesive layer, the signal light is first glued on and then screwed on from the back. This is particularly advantageous for large front panels, since the installation can be carried out by just one person. A flat and compact design The luminaire housing is achieved in that the rear wall of the housing is designed as a printed circuit board and the light-emitting diode is attached to it.

Weiter bezieht sich die vorliegende Erfindung auf einen elektrischen Druckknopfschalter mit Leuchtanzeige, der ein Schaltergehäuse und darin längsachsial zwischen einer Ruhe- und einer Arbeitslage verschiebbar gelagerten und frontseitig den Druckknopfschalter bildenden Schaltschieber aufweist, in welchem Schaltschieber eine Leuchtdiode angeordnet ist.Furthermore, the present invention relates to an electrical push button switch with a light indicator, which has a switch housing and therein a longitudinally axially displaceable switch between a rest position and a working position and on the front forming the push button switch, in which switch slide a light emitting diode is arranged.

Derartige Druckknopfschalter sind beispielsweise in der DE-AS 1 290 620 beschrieben. Sie besitzen den Nachteil, dass der Schaltschieber frontseitig eine lichtdurchlässige Platte trägt, welche die Leuchtdiode überdeckt und dadurch Licht absorbiert, was die visuelle Erkennbarkeit des Schaltzustandes des Schalters erschwert.Such push button switches are described for example in DE-AS 1 290 620. They have the disadvantage that the switch slide carries a translucent plate on the front, which covers the light-emitting diode and thereby absorbs light, which makes it difficult to visually recognize the switching state of the switch.

Die vorliegende Erfindung stellt sich die Aufgabe, einen Druckknopfschalter dieser Art derart zu verbessern, dass die Erkennbarkeit seines Schaltzustandes wesentlich verbessert wird.The object of the present invention is to improve a push button switch of this type in such a way that the recognizability of its switching state is significantly improved.

Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass die Leuchtdiode den Druckknopf am frontseitigen Ende des Schaltschiebers bildet, und dass das Schaltergehäuse frontseitig eine die Leuchtdiode umgebende Manschette bildet. Die Erfindung bewirkt die Vorteile, dass als Druckknopf und Lichtquelle eine handelsübliche Leuchtdiode verwendet werden kann und dass dem Schalter eine geringe Bauhöhe gegeben werden kann.According to the invention, this object is achieved in that the light-emitting diode forms the push button at the front end of the slide switch, and in that the switch housing on the front reverses the light-emitting diode cuff. The invention has the advantages that a commercially available light-emitting diode can be used as a push button and light source and that the switch can be given a small overall height.

Anhand der beiliegenden schematischen Zeichnung wird die Erfindung beispielsweise erläutert. Es zeigen:

  • Fig. 4 eine Draufsicht auf Fig. 3 und
  • Fig. 5 einen Querschnitt durch ein Ausführungsbeispiel eines elektrischen Druckknopfschalters, wobei Teile weggelassen sind.
The invention is explained, for example, with the aid of the attached schematic drawing. Show it:
  • 1 shows a cross section through a first embodiment of a signal lamp,
  • 2 is a plan view of FIG. 1,
  • 3 shows a cross section through a second exemplary embodiment of a signal lamp,

In Fig. 1 bezeichnet die Hinweisziffer 1 die Frontplatte einer Montagewand in der eine Signalleuchte 2 montiert ist. Die Signalleuchte 2 weist ein Gehäuse auf, das eine nach vorne konisch zulaufende Manschette 3 bildet, in die rückseitig eine Rückwand 4 eingerastet ist. Die die Seitenwand des Gehäuses bildende Manschette 3 ist an ihrem rückseitigen Ende mit einer umlaufenden Kante 5 versehen, die in der Ebene der Rückseite der Rückwand liegt. Im Gehäuse ist parallel zur Rückwand 4 eine Leiterplatte 6 angeordnet, welche mit Distanzhalteelementen 7 in paralleler Ausrichtung zur Rückwand 4 gehalten ist. Auf die Leiterplatte 6 aufgelötet sind eine Leuchtdiode 8 und zwei Vorwiderstände 9. Die Leuchtdiode 8 weist einen lichtdurchlässigen, quaderförmigen Mantel auf, der frontseitig eine von der Manschette 10'gebildete runde Durchbrechung abschliesst. Die Rückwand 4 ist rückseitig mit einem materialschlüssigen Zapfen versehen, durch den die beiden Anschlussleiter 12 für die Leuchtdiode geführt sind. Für das Hindurchführen des Zapfens 11 durch die Montagewand 1 ist in dieser eine Bohrung 13 angebracht. Weist der Zapfen 11 ein Aussengewinde auf, so kann die Leuchte durch eine von der Rückseite der Montagewand 1 her auf den Zapfen 11 aufgeschraubte Mutter 14 festgespannt werden. Zur Befestigung der Leuchte ist es indessen auch möglich, auf der rückseitigen FLäche 15 eine Selbstklebeschicht anzubringen und das Leuchtengehäuse mittels dieser Schicht auf der Montagewand l festzukleben.In Fig. 1, reference numeral 1 denotes the front panel of a mounting wall in which a signal lamp 2 is mounted. The signal lamp 2 has a housing which forms a sleeve 3 which tapers conically towards the front and into which a rear wall 4 is latched at the rear. The sleeve 3 forming the side wall of the housing is provided at its rear end with a circumferential edge 5 which lies in the plane of the rear of the rear wall. A circuit board 6, which has spacers, is arranged in the housing parallel to the rear wall 4 elements 7 is held in parallel alignment with the rear wall 4. A light-emitting diode 8 and two series resistors 9 are soldered onto the printed circuit board 6. The light-emitting diode 8 has a translucent, cuboid-shaped jacket, which closes a round opening formed by the sleeve 10 ′ on the front side. The rear wall 4 is provided on the back with a material-locking pin through which the two connecting conductors 12 for the light-emitting diode are guided. For the passage of the pin 11 through the mounting wall 1, a bore 13 is made in this. If the pin 11 has an external thread, the lamp can be clamped by a nut 14 screwed onto the pin 11 from the rear of the mounting wall 1. To attach the lamp, it is also possible, however, to apply a self-adhesive layer to the rear surface 15 and to glue the lamp housing onto the mounting wall 1 by means of this layer.

Um die Bauhöhe des Leuchtengehäuses möglichst niedrig zu halten ist nach einem nicht dargestellten Ausführungsbeispiel die Rückwand 4 als Leiterplatte ausgebildet, so dass die Leuchte um die Dicke der Leiterplatte 6 und um die Höhe der Distanzhalteeelemente 7 niedriger ; ausführbar ist.In order to keep the overall height of the lamp housing as low as possible, the rear wall 4 is designed as a printed circuit board according to an exemplary embodiment, not shown, so that the lamp is lower by the thickness of the printed circuit board 6 and by the height of the spacer elements 7; is executable.

Im Ausführungsbeispiel nach Fig. 3 und 4 bezeichnen gleiche Hinweisziffern gleich oder aequivalente Teile wie im Beispiel nach Fig. 1 und 2, so dass auf deren wiederholende Beschreibung verzichtet wird. Bei diesem Ausführungsbeispiel ist die Querschnittsform des Leuchtengehäuses in der Draufsicht quadratisch im Unterschied zur runden Form des vorbeschriebenen Ausführungsbeispiels. Weiter sind bei diesem Ausführungsbeispiel an der Rückseite der Rückwand 4 anstelle des Zapfens 11 zwei Zapfen 16 und 17 vorhanden durch die je einer der beiden Anschlussleiter 12 geführt ist. Soll bei diesem Ausführungsbeispiel die Leuchte mittels einer Schraubenverbindung an der Montagewand 1 befestigt werden, genügt es, wenn einer der beiden Zapfen 16 oder 17 mit einem Aussengewinde versehen und auf diesem Zapfen eine Mutter 14 festgespannt ist. Auch bei diesem Ausführungsbeispiel kann die rückseitige Fläche 15 der Rückwand 4 mit einer Selbstklebeschicht versehen und die Leuchte auf der Sichtseite der Frontplatte festgeklebt sein. Die Bohrungen 13 können in einfacher Weise mittels einer Lehre ausgeführt werden.In the exemplary embodiment according to FIGS. 3 and 4, the same reference numerals designate the same or equivalent parts as in the example according to FIGS. 1 and 2, so that their repeated description is dispensed with. In this embodiment, the cross-sectional shape of the lamp housing is square in plan view in contrast to the round shape of the embodiment described above. Furthermore, in this embodiment, two pins 16 and 17 are provided on the back of the rear wall 4 instead of the pin 11, through which one of the two connecting conductors 12 is guided. If in this exemplary embodiment the lamp is to be fastened to the mounting wall 1 by means of a screw connection, it is sufficient if one of the two pins 16 or 17 is provided with an external thread and a nut 14 is tightened on this pin. In this embodiment too, the rear surface 15 of the rear wall 4 can be provided with a self-adhesive layer and the light fixture can be glued to the visible side of the front plate. The bores 13 can be carried out in a simple manner by means of a teaching.

Beim Druckknopfschalter in Fig. 5 bezeichnet die Hinweisziffer 18 das vordere Ende eines Schaltergehäuses, das in diesem Bereich eine Manschette bildet, die mit einer Führung 19 eine Oeffnung umgibt, welche einen rechteckigen oder runden Querschnitt haben kann und in die eine Leuchtdiode 20 mit ihrem lichtdurchlässigen Mantel hineinragt. Der Mantel der Leuchtdiode hat entsprechend der Querschnittsform der Führung 19 eine zylindrische oder eine quaderförmige Form. Im Schaltergehäuse 18 ist achsial verschiebbar ein Schaltschieber 21 gelagert, der eine zur Schalterachse quer orientierte Leiterplatte 22 trägt. Auf der Leiterplatte 22 ist die Leuchtdiode 20 befestigt.Sie bildet den Druckknopf des Schalters, der gegen den Druck einer Rückstellfeder 23 aus einer Ruhelage in eine Arbeitslage (oder umgekehrt) gedrückt werden kann. Der nicht dargestellte Teil des Schalters kann in bekannter Weise, so z.B. wie in der DE-AS l 290 620 gezeigt, gestaltet sein. Dadurch dass die Leuchtdiode 20 unmittelbar als Druckknopf des Schalters ausgebildet ist, wird die Erkennbarkeit der Leuchtanzeige wesentlich verbessert.In the push button switch in Fig. 5, the reference numeral 18 denotes the front end of a switch housing, which forms a sleeve in this area, which surrounds an opening with a guide 19, which can have a rectangular or round cross-section and into which a light-emitting diode 20 with its translucent Man tel protrudes. The jacket of the light-emitting diode has a cylindrical or cuboid shape in accordance with the cross-sectional shape of the guide 19. A switch slide 21, which carries a circuit board 22 oriented transversely to the switch axis, is mounted in the switch housing 18 so as to be axially displaceable. The light-emitting diode 20 is attached to the printed circuit board 22 and forms the push button of the switch, which can be pressed against the pressure of a return spring 23 from a rest position into a working position (or vice versa). The part of the switch, not shown, can be designed in a known manner, for example as shown in DE-AS 1 290 620. Because the light-emitting diode 20 is designed directly as a push button of the switch, the recognizability of the light-emitting display is significantly improved.
