Description

Die Erfindung bezieht sich auf eine Anzeigeleuchte, die aus einer Kleinglühlampe mit an ihrem Glasquetschfussende herausgeführten Stromzuführungen und aus einem Kunststoff-Sockel besteht, an dem ein Flansch und Nasen angeformt sind, zum bajonettartigen Einbau des Sockels in elektrische Geräte. Der Sockel weist im oberen Teil eine Aussparung zur Aufnahme der Lampe auf sowie zwei Sockelkontakte, an denen die Stromzuführungen angeschweisst sind und die die elektrische Kontaktgabe der Anzeigeleuchte ermöglichen.The invention relates to an indicator light, which consists of a small light bulb with power leads led out at its glass pinch foot end and a plastic base, on which a flange and lugs are formed, for bayonet-like installation of the base in electrical devices. The base has a recess in the upper part for receiving the lamp and two base contacts, to which the power supply lines are welded and which allow the indicator light to be electrically contacted.

Viele Variationen derartiger Anzeigeleuchten befinden sich z.Z. auf dem Markt und werden in vielen Bereichen eingesetzt. Bei einigen Ausführungsformen ist die Lampe im Sockelkörper durch Halte- bzw. Rastelemente an den im Sockelkörper liegenden Enden der Sockelkontakte lagefixiert gehaltert und bei anderen Ausführungsformen durch im Sockelkörper angeformte Führungs- und Rastelemente. Im einen wie im anderen Fall können die Stromzuführungen sowohl mittels Klemmen als auch mittels Schweissen mit den Sockelkontakten verbunden sein.There are currently many variations of such indicator lights. on the market and are used in many areas. In some embodiments, the lamp is held in a fixed position in the base body by holding or latching elements on the ends of the base contacts lying in the base body and in other embodiments by guide and latching elements molded into the base body. In one case as in the other, the power supply lines can be connected to the base contacts both by means of clamps and by means of welding.

Allen Ausführungsformen gemeinsam ist die Tatsache, dass die Sockelkontakte in Nuten parallel zur Sockellängsachse angeordnet und deren kontaktierende Enden entsprechend umgebogen sind.Common to all of the embodiments is the fact that the base contacts are arranged in grooves parallel to the longitudinal axis of the base and their contacting ends are bent accordingly.

Bei Kontaktierung der Lampe in dem Sockel durch Klemmen ist es möglich, dass sich beispielsweise durch Vibration oder andere Einflüsse die Verbindungsstelle zwischen Stromzuführungen und Sockelkontakten löst und damit die Zuverlässigkeit der Anzeigeleuchte in ihrer Funktionsweise unzureichend ist. Eine Verbesserung der Kontaktierung ist durch Schweissen erreicht worden, wobei jedoch meistens dieser Arbeitsschritt vor dem Einsetzen der Lampe erfolgt und sich beim Einsetzen die Schweissstellen lösen können.When contacting the lamp in the base by means of clamps, it is possible that the connection point between the power supply lines and base contacts is loosened, for example by vibration or other influences, and the reliability of the indicator light is therefore insufficient in its functioning. An improvement in the contacting has been achieved by welding, although this work step usually takes place before the lamp is inserted and the welding points can be loosened when the lamp is inserted.

Nach der US-A-3 950 061 ist auch eine Fassung zur Aufnahme von Kleinlampen mit Glassockel bekannt, bei der die Halterung der Lampe durch Kontaktfedern und in der Aufnahmeöffnung angeordnete Rippen erfolgt.According to US-A-3 950 061, a holder for receiving small lamps with a glass base is also known, in which the lamp is held by contact springs and ribs arranged in the receiving opening.

Der Erfindung liegt die Aufgabe zugrunde, eine Anzeigeleuchte zu schaffen, mit der die Fertigungskosten erheblich gesenkt werden können, bei der jedoch trotzdem die Kontaktierung zwischen den Stromzuführungen und den Sockelkontakten während des Betriebs der Anzeigeleuchte zuverlässig gewährleistet ist.The invention has for its object to provide an indicator light with which the manufacturing costs can be significantly reduced, but in which nevertheless the contact between the power supply lines and the base contacts is reliably ensured during operation of the indicator light.

Ein Senken der Fertigungskosten lässt sich durch Materialeinsparung, Verkürzung der Herstellzeit und Verminderung des Ausschusses bei der Fertigung erreichen.A reduction in manufacturing costs can be achieved by saving material, shortening the manufacturing time and reducing the amount of scrap in manufacturing.

Die gestellte Aufgabe wird mittels der Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.The stated object is achieved by means of the features of the characterizing part of claim 1.

Weitere Einzelheiten ergeben sich aus den abhängigen Ansprüchen.Further details emerge from the dependent claims.

Ein Ausführungsbeispiel ist in Zeichnungen dargestellt und wird im folgenden näher beschrieben. Es zeigen:

  • Figur 1 eine teilweise geschnittene Seitenansicht des Sockels der Anzeigeleuchte ohne Lampe und ohne Sockelkontakte,
  • Figur 1b eine Draufsicht des Sockels nach Figur 1a,
  • Figur 2a eine teilweise geschnittene Seitenansicht der Anzeigeleuchte und
  • Figur 2b eine Draufsicht der Anzeigeleuchte nach Figur 2a.
An embodiment is shown in drawings and is described in more detail below. Show it:
  • FIG. 1 shows a partially sectioned side view of the base of the indicator lamp without lamp and without base contacts,
  • 1b shows a top view of the base according to FIG. 1a,
  • Figure 2a is a partially sectioned side view of the indicator light and
  • Figure 2b is a plan view of the indicator light of Figure 2a.

Der in den Figuren dargestellte Sockel 1 einer Anzeigeleuchte besteht aus einem zylinderförmigen Teil 2, das an seinem unteren Ende teilweise von einem Flansch 3 umgeben ist. Dieser Flansch 3 liegt bei eingebauter Anzeigeleuchte beispielsweise unterhalb einer Leiterplatte an, wobei als Gegenhalt zwei einander gegenüberliegende Nasen 4 dienen, die etwas oberhalb des Flansches 3 am zylinderförmigen Teil 2 des Sockels 1 angeformt sind. Unterhalb des Flansches 3 ist am zylinderförmigen Teil 2 ein Haltegriff 5 angeformt, der das Einsetzen und Auswechseln der Anzeigeleuchte erleichtert.The base 1 of an indicator light shown in the figures consists of a cylindrical part 2 which is partially surrounded by a flange 3 at its lower end. When the indicator light is installed, this flange 3 abuts, for example, below a printed circuit board, with two mutually opposite lugs 4 serving as counter-support, which are molded onto the cylindrical part 2 of the base 1 somewhat above the flange 3. Below the flange 3, a handle 5 is formed on the cylindrical part 2, which facilitates the insertion and replacement of the indicator light.

Innerhalb des zylinderförmigen Teils 2 des Sokkels 1 ist eine Aussparung 6 vorgesehen, die sich in drei unterschiedliche Abschnitte gliedert. Von oben her gesehen ist der erste Abschnitt der Aussparung 6 zylinderförmig und weist an seinem Umfang vier parallel zur Sockellängsachse x verlaufende, elastische Stege 7 auf, die für eine richtige Zentrierung und einen festen Sitz der Lampe 8 sorgen.A recess 6 is provided within the cylindrical part 2 of the base 1, which is divided into three different sections. Seen from above, the first section of the recess 6 is cylindrical and has on its circumference four elastic webs 7 which run parallel to the longitudinal axis x of the base and which ensure correct centering and firm seating of the lamp 8.

Der zweite Abschnitt der Aussparung 6 ist in seinem Querschnitt im grossen und ganzen dem Glasquetschfuss 9 der Lampe angepasst, so dass dieser im zweiten Abschnitt der Aussparung 6 verdrehsicher Aufnahme findet. Als Tiefenanschlag dient die Quetschkante der Lampe 8 und die Oberkante 10 des zweiten Abschnitts der Aussparung 6.The cross section of the second section of the recess 6 is largely matched to the glass pinch base 9 of the lamp, so that it is held in the second section of the recess 6 so that it cannot rotate. The pinch edge of the lamp 8 and the upper edge 10 of the second section of the recess 6 serve as the depth stop.

Der dritte Abschnitt der Aussparung 6 besteht aus zwei Schrägen 11, an denen beim Einsetzen der Lampe 8 deren Stromzuführungen 12 entlanggleiten und so an ihren vorbestimmten Ort geführt werden.The third section of the recess 6 consists of two bevels 11, along which the current leads 12 slide when the lamp 8 is inserted and are thus guided to their predetermined location.

Die Sockelkontakte 13 der Anzeigeleuchte sind sehr kleine, einfach und billig herzustellende Zungen 14, deren Montage auf einfache Weise mechanisiert werden kann. Die Zungen 14 sind in zwei einander gegenüberliegende Schlitze 15 im Bereich des Flansches 3 gesteckt, wobei aus den Zungen 14 herausgebogene Laschen 16 in zweite Aussparungen 17 in dem Sockel 1 einrasten und somit ein fester Sitz gewährleistet ist. Die Befestigung der Sockelkontakte 13 in den Schlitzen 15 kann aber auch mittels einer an den Sockelkontakten 13 angebrachten Durchreissnietung erfolgen (nicht dargestellt). Durch eine Öffnung 18 in den Zungen 14 sind die Enden der Stromzuführungen 12 der Lampe 8 geführt, umgebogen und mit den Sockelkontakten 13 verschweisst. Das Schweissen bietet gegenüber einer Klemmverbindung den Vorteil, dass es zu keiner Kontaktkorrosion kommen kann.The base contacts 13 of the indicator light are very small, simple and inexpensive to produce tongues 14, the assembly of which can be mechanized in a simple manner. The tongues 14 are inserted into two mutually opposite slots 15 in the region of the flange 3, with tabs 16 bent out of the tongues 14 latching into second cutouts 17 in the base 1, thus ensuring a firm fit. The base contacts 13 can also be fastened in the slots 15 by means of a rivet rivet attached to the base contacts 13 (not shown). The ends of the power leads 12 of the lamp 8 are guided through an opening 18 in the tongues 14, bent over and welded to the base contacts 13. Welding offers the opposite of a clamp connection Advantage that there can be no contact corrosion.

Die ausserhalb des Sockels 1 liegenden Enden 19 der Sockelkontakte 13 sind etwas nach oben gebogen, wodurch die Sockelkontakte 13 federnd an der Unterseite einer Leiterplatte o.ä. anliegen. Mittels einer geprägten Erhebung 20 an den Enden 19 wird eine gute Kontaktierung der Anzeigeleuchte mit den Leiterbahnen der Leiterplatte gewährleistet.The ends 19 of the base contacts 13 lying outside the base 1 are bent somewhat upwards, as a result of which the base contacts 13 are resilient on the underside of a printed circuit board or the like. issue. An embossed elevation 20 at the ends 19 ensures good contacting of the indicator light with the conductor tracks of the printed circuit board.
