Abstract

Projecting over the rear side of the housing (3, 14, 17, 18) there are terminals (5, 16) which can be covered by a protective cover (6, 19) which can be displaced axially on the housing. In order that the protective cover can be positioned in its effective position quickly and without effort it is provided that the protective cover (6, 19) can be displaced in a straight line and has perforations (6', 23) allocated to the terminals (5, 16). In addition, the protective cover (6, 19) can assume a first and a second position, the terminals (5, 16) projecting through the perforations (6', 23) beyond the protective cover in the first position, and being located inside the protective cover (6, 19) in the second position. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf ein Befehls- oder Meldegerät gemäss dem Oberbegriff des Patentanspruchs 1.The present invention relates to a command or signaling device according to the preamble of claim 1.

Ein Befehlsgerät dieser Art ist beispielsweise in der DE-PS 587 373 beschrieben. Das zylindrische Gehäuse ist mit einem Aussengewinde versehen, auf das nach Art einer Verschluss­mutter die Abdeckhaube aufgeschraubt ist. Die an die Kontakt­fahnen anzuschliessenden Leiter werden durch eine Durch­brechung in der vom Gehäuse getrennten Abdeckhaube hindurch­geschoben und an den Kontaktfahnen angeschlossen. Hernach wird die Abdeckhaube über die Leiter gestreift, bis sie zur Anlage mit dem Gehäuse kommt und auf dieses aufgeschraubt. Diese bekannte Lösung hat einerseits den Nachteil, dass die Abdeckhaube verloren gehen kann und anderseits, dass das Anbringen und das Entfernen der Abdeckhaube umständlich ist.A command device of this type is described for example in DE-PS 587 373. The cylindrical housing is provided with an external thread onto which the cover hood is screwed in the manner of a lock nut. The conductors to be connected to the contact lugs are pushed through an opening in the cover hood separated from the housing and connected to the contact lugs. Then the cover is slipped over the ladder until it comes into contact with the housing and screwed onto it. This known solution has the disadvantage on the one hand that the cover can be lost and on the other hand that the attachment and removal of the cover is cumbersome.

Die vorliegende Erfindung stellt sich die Aufgabe, an einem Gerät der eingangs erwähnten Art die genannten Nachteile zu beseitigen.The present invention has as its object to eliminate the disadvantages mentioned on a device of the type mentioned.

Erfindungsgemäss erfolgt dies durch die kennzeichnenden Merk­male des Anspruchs 1.According to the invention, this is done by the characterizing features of claim 1.

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

  • Fig. 1 eine Meldeleuchte mit teilweisem Längsschnitt längs der Linie I-I in Fig. 2,
  • Fig. 2 einen teilweisen Schnitt durch die Meldeleuchte gemäss Fig. 1 längs der Linie II-II in Fig. 1,
  • Fig. 3 ein Drucktastenschalter in perspektivischer Ansicht, wobei Teile weggelassen sind mit einem zweiten Aus­führungsbeispiel einer Abdeckhaube,
  • Fig. 4 einen Schnitt längs der Linie IV-IV in Fig. 3,
  • Fig. 5 eine Ansicht in Richtung des Pfeiles V in Fig. 3 und
  • Fig. 6 ein zweites Ausführungsbeispiel einer Abdeckhaube.
The invention is explained, for example, with the aid of the attached schematic drawing. Show it:
  • 1 is a signal lamp with a partial longitudinal section along the line II in Fig. 2,
  • 2 shows a partial section through the indicator light according to FIG. 1 along the line II-II in FIG. 1,
  • 3 shows a pushbutton switch in perspective view, parts being omitted with a second exemplary embodiment of a covering hood,
  • 4 shows a section along the line IV-IV in FIG. 3,
  • Fig. 5 is a view in the direction of arrow V in Fig. 3 and
  • Fig. 6 shows a second embodiment of a cover.

Die in den Fig. 1 und 2 gezeigte Meldeleuchte weist eine lichtdurchlässige Kalotte 1 in einem Frontrahmen 2 auf, an den ein zylindrisches Gehäuse 3 anschliesst. Dieses ist zur Befestigung an einer Montagewand mit einem Aussengewinde 4 und einer darauf geschraubten, nicht dargestellten Überwurf­mutter versehen. An dem der Kalotte 1 abgewandten Ende des Gehäuses 3 wird dieses von zwei Anschlusskontaktfahnen 5 überragt. An diese werden die elektrischen Leiter ange­schlossen (Löten, Steckkontakt etc.). Um die Anschlusskontakt­fahnen 5 nach dem Anschliessen der Leiter gegen eine Berüh­rung zu schützen ist im Gehäuse 3 axial verschiebbar und unverlierbar eine Abdeckhaube 6 gelagert. Diese weist in der Verlängerung der Anschlusskontaktfahnen 5 Durchbrechungen 6′ auf. Im Gehäuse 3 ist weiter eine axiale Führung 7 vorhanden, in der die Abdeckhaube 6 mit einem Führungsstift 8 axial verschiebbar geführt ist. Zu gegenüber liegenden Seiten des Führungsstiftes 8 ist die Schutzhaube 6 mit zwei Rastfedern 9 mit Rastnasen 10 versehen, welche den Verschiebeweg der Abdeckhaube 6 nach einer Richtung begrenzen und sie dadurch unverlierbar im Gehäuse 3 halten. Die Rastfedern 10 greifen in zwei neben der Führung 7 vorhandene Ausnehmungen 11. Die Abdeckhaube 6 ist zwischen der mit ausgezogenen Strichen ge­zeigten Grundstellung einerseits und der mit strichpunktier­ten Strichen gezeigten Schutzstellung anderseits verschiebbar. In die Ausnehmungen 10 und 11 münden je eine Bohrung 13, die der Aufnahme der Rastnase 10 dienen. Oberhalb der Bohrung 13 sind die Ausnehmungen 11 im Verschiebeweg der Rastnasen 10 mit einer Keilfläche 12 versehen, welche dazu dient, die Rastnase 10 nach innen zu drücken, wenn die Abdeckhaube 6 nach aussen gezogen wird.The indicator light shown in FIGS. 1 and 2 has a translucent dome 1 in a front frame 2, to which a cylindrical housing 3 connects. This is provided for attachment to a mounting wall with an external thread 4 and a screwed nut, not shown, screwed thereon. At the end of the housing 3 facing away from the calotte 1, this is surmounted by two connecting contact tabs 5. The electrical conductors are connected to these (soldering, plug contact, etc.). In order to protect the terminal contact tabs 5 against contact after the conductors have been connected, a cover 6 is axially displaceable and captive in the housing 3. This has 5 openings 6 'in the extension of the terminal contact tabs. In the housing 3 there is also an axial guide 7 in which the cover 6 is guided axially displaceably with a guide pin 8. On opposite sides of the guide pin 8, the protective hood 6 is provided with two locking springs 9 with locking lugs 10, which limit the displacement of the cover 6 in one direction and thereby limit it hold captive in the housing 3. The detent springs 10 engage in two recesses 11 next to the guide 7. The cover 6 can be displaced between the basic position shown with solid lines on the one hand and the protective position shown with dash-dotted lines on the other hand. In the recesses 10 and 11 each open a bore 13 which serve to receive the locking lug 10. Above the bore 13, the recesses 11 are provided in the displacement path of the locking lugs 10 with a wedge surface 12 which serves to press the locking lug 10 inwards when the cover 6 is pulled outwards.

Die beschriebene Meldeleuchte wird mit in der Grundstellung befindlicher Abdeckhaube 6 montiert (mit ausgezogenen Strichen gezeigt). Nach dem Anschliessen der Anschlussleiter an die Kontaktfahnen 5 wird zum Berührungsschutz dieser Anschluss­stellen die Abdeckhaube 6 nach aussen in die strichpunktierte Schutzstellung gezogen, wozu eine vergleichsweise geringe Kraft erforderlich ist. Dabei gleiten die Rastnasen 10 über die Keilflächen 12 und biegen die Rastfedern 9 nach innen gegen die Führung 7. Nach den Keilflächen 12 springen während des weiteren Herausziehens die Rastnasen 10 in die Bohrungen 13 und fixieren die Abdeckhaube 6 in ihrer Schutzstellung. Ein Eindrücken der Abdeckhaube 6 ist ohne deren Beschädigung nicht mehr möglich. Wollte man die Abdeckhaube 6 wieder in die Grundstellung zurückschieben, so müssten mit einem ent­sprechenden Werkzeug die Rastfedern 9 zusammengedrückt und der Eingriff der Rastnasen 10 in die Bohrungen 13 gelöst werden.The indicator light described is mounted with the cover 6 in the basic position (shown with solid lines). After connecting the connection conductors to the contact lugs 5, the cover 6 is pulled outward into the dash-dotted protective position to protect against contact with these connection points, for which purpose a comparatively small force is required. The locking lugs 10 slide over the wedge surfaces 12 and bend the locking springs 9 inwards against the guide 7. After the wedge surfaces 12, the locking lugs 10 jump into the bores 13 during further extraction and fix the cover 6 in its protective position. Pressing in the cover 6 is no longer possible without damaging it. If one wanted to push the cover 6 back into the basic position, the detent springs 9 would have to be compressed with a corresponding tool and the engagement of the detents 10 in the bores 13 would have to be released.

Wollte man die Möglichkeit schaffen, dass die Abdeckhaube 6 aus der ausgefahrenen Stellung wieder zurück in die ver­senkte Stellung gebracht werden kann, ohne dass sie ihre Schutzfunktion verliert, so könnte dies dadurch geschehen, dass die nach oben gerichtete Seite der Rastnasen 10 mit einem keilförmigen Anzug versehen wird. Dadurch wird die Möglichkeit geschaffen, durch einen Druck auf die Abdeckhaube 6 die Rast­federn 9 nach innen zu biegen. Dabei ist darauf zu achten, dass der Anzug einer solchen Keilflanke zur Wahrung der Schutzfunktion so gewählt wird, dass zum Eindrücken der Schutzhaube 6 ein Mehrfaches jener Kraft notwendig ist, die das Herausziehen der Schutzhaube 6 erfordert.If one wanted to create the possibility that the cover 6 can be brought back from the extended position back into the lowered position without losing its protective function, this could be done by the upward-facing side of the locking lugs 10 with a wedge-shaped suit is provided. This creates the possibility of bending the detent springs 9 inwards by pressing the cover 6. It is important to ensure that the tightening of such a wedge flank is selected to maintain the protective function in such a way that a multiple of the force required to pull out the protective hood 6 is necessary to press in the protective hood 6.

Die Fig. 3 zeigt den unteren Teil eines Schaltergehäuses 14 eines Tastschalters, in dem die Schalttaste gelagert ist, die durch nicht dargestellte Mittel die im daran befestigten Schaltelement 15 untergebrachten Schaltkontakte betätigt. Diese sind elektrisch leitend mit den Anschlusskontaktfahnen 16 (Fig. 5) verbunden. Das Schaltelement 15 weist ein Gehäuse bestehend aus Gehäuseoberteil 17 und Gehäuseunterteil 18 auf, die miteinander fest verbunden sind. Das untere Ende des Schaltergehäuses 14 ist lösbar mit dem Schaltelement 15 bzw. dem Gehäuseoberteil 17 verbunden. Analog dem Beispiel nach Fig. 1 und 2 ist das Schaltelement 15 mit einer Abdeckhaube 19 versehen, welche den Zweck hat, die Anschlusskontaktfahnen 16 nach dem Anschliessen der Leitungen vor einer ungewollten Berührung zu schützen. Diese Schutzhaube 19 kann, wie aus den Fig. 4 und 5 ersichtlich ist, drei Stellungen einnehmen: Die erste Stellung (Pos. 1 in Fig. 4 links und Fig. 5) ist die eigentliche Grundstellung, in der sich der Boden 20 der Abdeckhaube 19 nahe dem Schaltelement 15 aber mit Abstand zu diesem befindet. In dieser Stellung ragen die Anschluss­kontaktfahnen 16 durch die Durchbrechungen 23 im Boden 20 hindurch und sind zugänglich und frei für das Anschliessen der Leiter.3 shows the lower part of a switch housing 14 of a pushbutton switch, in which the switch button is mounted, which actuates the switch contacts accommodated in the switch element 15 attached to it by means not shown. These are connected in an electrically conductive manner to the terminal contact tabs 16 (FIG. 5). The switching element 15 has a housing consisting of upper housing part 17 and lower housing part 18, which are firmly connected to one another. The lower end of the switch housing 14 is detachably connected to the switching element 15 or the upper housing part 17. Analogously to the example according to FIGS. 1 and 2, the switching element 15 is provided with a covering hood 19, which has the purpose of protecting the connection contact tabs 16 against unwanted contact after the lines have been connected. As can be seen from FIGS. 4 and 5, this protective hood 19 can assume three positions: The first position (item 1 in FIG. 4 on the left and FIG. 5) is the actual basic position, in which the bottom 20 of the cover 19 is close to the switching element 15 but at a distance from it. In this position, the connection contact tabs 16 protrude through the openings 23 in the base 20 and are accessible and free for connecting the conductors.

In dieser ersten Stellung (Pos. 1) sind weiter zwei mit der Abdeckhaube 19 einstückig gefertigte Entriegelungsschieber 21 mit ihren freien Enden 22 in Anschlag mit dem unteren Ende des Schaltergehäuses 14. Die Entriegelungsschieber 21 sind durch entsprechende Durchbrechungen in der Wand des Schalt­elementes 15 hindurch geführt.In this first position (item 1) there are two unlocking slides 21 made in one piece with the cover 19 with their free ends 22 in abutment with the lower end of the switch housing 14. The unlocking slides 21 are guided through corresponding openings in the wall of the switching element 15 .

In der zweiten Stellung (Pos. 2, Fig. 3 und 5) ist die Abdeck­haube 19 über die Anschlusskontaktfahnen 16 heraus gezogen, so dass sie diese gegen eine unerwünschte Berührung schützt. In dieser zweiten Stellung hat die Abdeckhaube 19 einen grösseren Abstand zum Schaltelement 15 als in der ersten Stellung.In the second position (items 2, 3 and 5), the cover 19 is pulled out over the connection contact tabs 16, so that it protects them against undesired contact. In this second position, the cover 19 is at a greater distance from the switching element 15 than in the first position.

In der dritten Stellung (Pos. 3, Fig. 4 rechts) ist die Abdeck haube 19 mit ihrem Boden 20 fast ganz an das Schaltelement 15 herangedrückt. Das Ende 22 des Entriegelungsschiebers ist dabei zwischen das Ende des Schaltergehäuses 14 und die Wand des Schaltelementes 15 geschoben. Die Enden des Entriegelungs­schiebers 21 haben dabei das Ende des Schaltergehäuses 14 elastisch nach innen gebogen und die Rastverbindungsmittel (24, 25) zwischen dem Schaltergehäuse 14 und dem Schaltele­ment 15 gelöst. Diese Rastverbindungsmittel bestehen aus zwei diametral gegenüberliegenden Durchbrechungen 24 im Schalter­gehäuse 14, und je einer zugeordneten Rastnase 25 an der Innenseite des Schaltelementes 15.In the third position (Pos. 3, Fig. 4 right) the cover 19 is almost completely pressed with its bottom 20 to the switching element 15. The end 22 of the unlocking slide is pushed between the end of the switch housing 14 and the wall of the switching element 15. The ends of the unlocking slide 21 have the end of the switch housing 14 bent elastically inwards and the latching connection means (24, 25) between the switch housing 14 and the switching element 15 released. These latching connection means consist of two diametrically opposite openings 24 in the switch housing 14, and one associated latching lug 25 on the inside of the switching element 15.

Vier an der Abdeckhaube 19 achssymmetrisch angeordnete Feder­arme 26, welche mit einer Klaue 27 eine Schulter 28 der Aussenseite des Schaltelementes 15 hintergreifen, begrenzen den Auszug der Schutzhaube 19 und bestimmen ihre zweite Stellung (Pos. 2). In dieser Stellung untergreifen weiter vier achssymmetrisch an der Schutzhaube 19 angeordnete Feder­arme 29 mit je einer Rastnase 30 eine zugeordnete Schulter 31 an der Schaltelementaussenseite. Der Anzug der Keilflanken an der Rastnase 30 bestimmt (nebst dem elastischen Verhalten der Federarme 29) die Kraft, die auf die Abdeckhaube 19 aus­geübt werden muss, damit diese aus der zweiten Stellung in die erste zurückgeschoben werden kann. Die Federarme 29 ver­hindern somit ein ungewolltes Zurückstellen der Schutzhaube 19 aus der zweiten in die erste Stellung.Four spring arms 26 arranged axially symmetrically on the cover hood 19, which engage behind a shoulder 28 on the outside of the switching element 15 with a claw 27, limit the pull-out of the protective hood 19 and determine its second position (item 2). In this position, four spring arms 29, each arranged axially symmetrically on the protective hood 19, each with a detent 30, engage under an associated shoulder 31 on the outside of the switching element. The tightening of the wedge flanks on the locking lug 30 determines (in addition to the elastic behavior of the spring arms 29) the force which must be exerted on the cover 19 so that it can be pushed back from the second position into the first. The spring arms 29 thus prevent an unintentional return of the protective hood 19 from the second to the first position.

In der ersten Stellung übergreifen die vier Rastnasen 30 der Federarme 29 eine Schulter 32 und bestimmen damit die für ein Herausziehen der Schutzhaube 19 notwendige Kraft. Ein unbeabsichtigtes Herausziehen der Abdeckhaube 19 wird damit verhindert; mit anderen Worten, die Federarme 29 halten die Abdeckhaube 19 in Richtung der zweiten Stellung mit begrenzter Kraft in der ersten Stellung fest. Nach der entgegengesetzten Richtung (d.h. in Richtung der dritten Stellung) ist die Abdeckhaube 19 durch die gegen das untere Ende des Schalter­gehäuses 14 anliegenden Entriegelungsschieber 21 mit be­grenzter Kraft gehalten.In the first position, the four locking lugs 30 of the spring arms 29 overlap a shoulder 32 and thus determine the force required for pulling out the protective hood 19. An unintentional removal of the cover 19 is prevented; in other words, the spring arms 29 hold the cover 19 in the direction of the second position in a more limited manner Force firmly in the first position. In the opposite direction (ie in the direction of the third position), the covering hood 19 is held with limited force by the unlocking slide 21 resting against the lower end of the switch housing 14.

Zusammenfassend ergibt sich, dass die Federarme 26 mit der Klaue 27 in Verbindung mit der Schulter 28 den Auszug der Schutzhaube 19 begrenzen (und unverlierbar am Schaltelement 15 halten), wogegen die Federarme 29 mit ihren Rastnasen 30 (bzw. deren Keilflankenneigung) und dem Zusammenwirken mit den Schultern 31 und 32 die Grösse jener Kraft bestimmen, mit denen die Abdeckhaube 19 aus der ersten in die zweite Stellung und aus dieser zurück in die erste Stellung gebracht werden kann.In summary, it follows that the spring arms 26 with the claw 27 in connection with the shoulder 28 limit the extraction of the protective hood 19 (and hold captively on the switching element 15), whereas the spring arms 29 with their locking lugs 30 (or their wedge flank inclination) and the interaction with the shoulders 31 and 32 determine the magnitude of the force with which the cover 19 can be brought from the first to the second position and from this back to the first position.

Das Zusammenwirken der Rastnasen 30 der Federarme 29 mit den Schultern 32 einerseits und die Berührung der Entriegelungs­schieber 21 mit dem unteren Ende des Schaltergehäuses 14 anderseits hält an dem die Abdeckhaube 19 in der Stellung 1 (Pos. 1) gegen eine Verschiebung in die dritte Stellung fest, in die sie nur durch Überwinden einer bestimmten Gegen­kraft gebracht werden kann.The interaction of the locking lugs 30 of the spring arms 29 with the shoulders 32 on the one hand and the contact of the unlocking slides 21 with the lower end of the switch housing 14 on the other hand holds the cover 19 in position 1 (item 1) against displacement into the third position into which it can only be brought by overcoming a certain counterforce.

Nach einem weiteren Ausführungsbeispiel (Fig. 6) können je­weils zwei benachbarte Federarme 26, 29 zu einem einzigen Federarm 33 zusammengefasst sein, der auf seiner dem Schalt­element 15 zugewandten Seite sowohl mit der Klaue 28 als auch mit der Rastnase 30 versehen ist. Hierdurch lässt sich die Kraft, mit der die Abdeckhaube 19 in der 1. und 2. Stellung gehalten ist oder für ein Entfernen oder Abreissen vom Schaltelement 15, vergrössern.According to a further exemplary embodiment (FIG. 6), two adjacent spring arms 26, 29 can each be combined to form a single spring arm 33, which has both the claw 28 and the claw 28 on its side facing the switching element 15 is provided with the latch 30. In this way, the force with which the cover 19 is held in the 1st and 2nd position or for removal or tearing off from the switching element 15 can be increased.

Diese Kraft kann weiter vergrössert werden indem die Fläche 34 hinterschnitten wird und die benachbarte Seite 35 des Federarmes 33 entsprechend ausgebildet in diese Hinterschnei­dung hineingreift. In diesem Fall müssen für einen Stellungs­wechsel oder ein Entfernen der Abdeckhaube 19 die Rastnasen 30 bzw. 27 nicht nur über eine der Schultern 28, 31, 32 ge­drückt bzw. gezogen und die Federarme nach aussen sondern auch nach der Seite hin gebogen werden.This force can be increased further by undercut the surface 34 and the adjacent side 35 of the spring arm 33, designed accordingly, engages in this undercut. In this case, for a change of position or removal of the cover 19, the latches 30 and 27 must not only be pressed or pulled over one of the shoulders 28, 31, 32 and the spring arms must be bent outwards but also to the side.
