Description

Die Erfindung betrifft eine Glühlampenfassung für Kraftfahrzeugleuchten bestehend aus einem hülsenförmigen Fassungskörper aus Kunststoff, der eine Querwandung aufweist, in die die Kontaktfedern von der Glühlampenseite her selbstrastend eingeschoben sind.The invention relates to a light bulb socket for motor vehicle lights consisting of a sleeve-shaped socket body made of plastic, which has a transverse wall, in which the contact springs are inserted from the light bulb side self-locking.

Bei den bekannten Fassungskörpern dieser Art, wie z. B. aus dem US-Patent 3,800,267, der australischen Patentanmeldung 26517/77und der GB-A-2168860 bekannt, ist die die Kontaktfeder aufnehmende Querwandung einstückig mit dem zylindrischen Hülsenteil hergestellt. Diese Ausführung hat zwar die allgemein bekannten Vorteile der Einteiligkeit, jedoch den Nachteil, dass die Kontaktfedern nur schwer und umständlich in die vertieft in dem zylindrischen Teil angeordnete Querwandung eingeschoben werden können. Sind die Kontaktfedern in ihrem die Glühlampe kontaktierenden Endabschnitt stark abgebogen oder abgewinkelt, müssen sie von der Glühlampeneinsatzseite her in die sehr tief liegende Querwandung eingefädelt und eingeschoben werden. Eine solche Montage der Kontaktfedern ist schwierig und erfordert ein großes Spiel zwischen Kontaktfeder und den Durchstecköffnungen in der Querwandung. Die Verbindung zwischen den Kontaktfedern und den Stromleitungskabeln ist auf Steckverbinder begrenzt, da eine Schneidklemmverbindung wegen der engen Raumverhältnisse innerhalb des hülsenförmigen Fassungskörpers zu beengt sind, um eine Schneidklemmverbindung nach Einsetzen der Kontaktfedern in die Querwandung durchführen zu könnenIn the known socket bodies of this type, such as. For example, from U.S. Patent 3,800,267, Australian Patent Application 26517/77 and GB-A-2168860, the transverse wall receiving the contact spring is made integral with the cylindrical sleeve member. Although this embodiment has the well-known advantages of one-piece, but the disadvantage that the contact springs can be inserted only with difficulty and cumbersome in the recessed in the cylindrical part arranged transverse wall. If the contact springs strongly bent or angled in their incandescent lamp contacting end portion, they must be threaded from the incandescent insert side into the very low transverse wall and inserted. Such an assembly of the contact springs is difficult and requires a large clearance between the contact spring and the insertion openings in the transverse wall. The connection between the contact springs and the power line cables is limited to connectors, as an insulation displacement connection are too cramped because of the narrow space within the sleeve-shaped socket body to perform an insulation displacement connection after insertion of the contact springs in the transverse wall can

Aus der WO-A-0126188 ist eine Netzfilter-Kombination bekannt, die aus drei miteinander zu verbindenden Einheiten (12, 18, 20) besteht. Die topfförmige Einhewit (18) dient zur Aufnahme eines Überspannungsschutzes und wird von der plattenförmigen Einheit (20), welche elektrische Kontakte trägt und mit Rastarmen versehen ist, abgedeckt. Von der Bodenseite her wird auf die topfförmige Einheit (18) die dritte Einheit (12), die ebenfalls elektrische Kontaktanschlüsse und einen Schalter trägt, mit einem Rastverschluss aufgesetzt. Diese dreiteilige Netzfilter-Kombination ist völlig anders aufgebaut als die Glühlampenfassungen für Kraftfahrzeugleuchten, von denen die Erfindung ausgeht.From WO-A-0126188 a net filter combination is known which consists of three units to be connected (12, 18, 20). The pot-shaped Einhewit (18) serves to receive an overvoltage protection and is covered by the plate-shaped unit (20), which carries electrical contacts and is provided with latching arms. From the bottom side, the third unit (12), which also carries electrical contact terminals and a switch, is placed on the cup-shaped unit (18) with a latching closure. This three-part net filter combination has a completely different structure than the bulb sockets for motor vehicle lights from which the invention proceeds.

Aufgabe der Erfindung ist es, das Einsetzen der Kontaktfedern in den sie tragenden Wandungsteil des Fassungskörpers zu erleichtern und den Fassungskörper so auszubilden, dass sein zylindrischer Teil weder durch seine Form noch Größe keine Behinderung mehr ist beim Einsetzen von stark abgewinkelten oder abgebogenen Kontaktfedern in den Fassungskörper.The object of the invention is to facilitate the onset of the contact springs in the supporting wall part of the socket body and the socket body in such a way that its cylindrical part neither by its shape nor size is no longer a hindrance to the onset of strongly angled or bent Contact springs in the socket body.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Querwandung von einer separaten, von der der Glühlampe abgewandten Rückseite her von dem hinteren Rand beabstandet vertieft in den zylinderförmigen Teil des Fassungskörpers eingesetzten Platte gebildet wird, die mit dem zylinderförmigen Teil vorzugsweise durch Verkleben, Verschweißen oder selbstrastend verbunden ist.This object is achieved in that the transverse wall of a separate, remote from the bulb rear side of the rear edge spaced recessed formed in the cylindrical portion of the socket body plate is formed with the cylindrical part preferably by gluing, welding or self-locking connected is.

Eine solche Ausgestaltung des Fassungskörpers ermöglicht neben dem leichten Einsetzen der Kontaktfeder in die sie tragende Wandung auch eine leichte Kontaktierung zwischen Kontaktfedern und den Stromzuleitungskabeln, da diese Kontaktierung außerhalb des zylinderförmigen Teils des Fassungskörpers erfolgt. All diese Vorteile ermöglichen erst eine Automatisierung der Bestückung des Fassungskörpers mit Kontaktfedern und der Kontaktierung zwischen Kontaktfedern und Stromzuleitungskabeln. Dadurch, dass die die Kontaktfedern tragende Platte von dem hinteren Rand beabstandet vertieft in den zylinderförmigen Teil des Fassungskörpers eingesetzt ist, entsteht ein die Kontaktierung zwischen Kontaktfedern und Stromleitungskabeln gegen Stöße und damit gegen Stromunterbrechung schützender, kragenförmiger Rand.Such an embodiment of the socket body allows in addition to the easy insertion of the contact spring in the wall carrying them also a slight contact between the contact springs and the power supply cables, since this contacting takes place outside of the cylindrical portion of the socket body. All these advantages allow only an automation of the assembly of the socket body with contact springs and the contact between the contact springs and power supply cables. Characterized in that the plate carrying the contact springs recessed from the rear edge inserted into the cylindrical portion of the socket body, there is a contact between contact springs and power cables against shocks and thus against power interruption protective, collar-shaped edge.

Ein weiterer Vorteil ist dadurch gegeben, dass die Stromleitungskabel senkrecht zur Längsmittelachse des Fassungskörpers verlaufend mit den Kontaktfedern verbunden sind und als Verbindung die Schneidklemmtechnik Verwendung findet. Eine solche Kontaktierung ist eine sichere stromleitende Verbindung und schnell und einfach durchzuführen.Another advantage is given by the fact that the power line cables are connected perpendicular to the longitudinal central axis of the socket body extending with the contact springs and the insulation displacement technology is used as a compound. Such a contact is a safe current-conducting connection and quick and easy to perform.

Um der Schneidklemmverbindung eine Zugentlastung zu geben, sind in den die Kontaktierung umgebenden, kragenförmigen Rand zum freien Ende hin geöffnete Schlitze eingebracht, in die die Stromleitungskabel eingeklemmt sind.In order to give the insulation displacement connection a strain relief, slots which are open towards the free end and into which the power supply cables are clamped are introduced into the collar-shaped edge surrounding the contacting.

Eine weitere vorteilhafte Ausgestaltung der Erfindung wird dadurch erreicht, dass die Kontaktfedern in dem Bereich, in dem sie von der Platte gehalten und in dem Bereich, in dem der Schneidklemmschlitz zur stromleitenden Verbindung mit dem Stromleitungskabel angeordnet ist, im Querschnitt U-förmig ausgebildet sind. Damit wird einmal der Sitz der Kontaktfeder in der Platte sicherer gestaltet und zum anderen ist die Schneidklemmverbindung pro Stromleitungskabel und Kontaktfeder doppelt ausgeführt, was einen Vorteil für die Sicherstellung einer guten Stromleitung und der mechanischen Festigkeit dieser Kontaktierung bildet.A further advantageous embodiment of the invention is achieved in that the contact springs are formed in the region in which they are held by the plate and in the region in which the insulation displacement slot for electrically conductive connection with the power cable, in cross-section U-shaped. Thus, once the seat of the contact spring in the plate is made safer and on the other hand, the insulation displacement connection per power cable and contact spring is made double, which forms an advantage for ensuring a good power line and the mechanical strength of this contact.

Die mechanische Festigkeit sowie die Einengung des Bewegungsspiels zwischen Kontaktfedern und der sie aufnehmenden Platte wird dadurch vergrößert, dass die Platte mit zur Fassungsrückseite weisenden, blockförmigen Vorsprüngen versehen ist, in die Nuten zur Aufnahme der Schenkelenden der im Querschnitt U-förmigen Kontaktfederabschnitte eingebracht sind.The mechanical strength and the narrowing of the play between the contact springs and the receiving plate is increased by the fact that the plate is provided with the rear side facing, block-shaped projections, are introduced into the grooves for receiving the leg ends of cross-sectionally U-shaped contact spring portions.

Zur weiteren Erhöhung der Kontaktsicherheit zwischen Kontaktfedern und Stromzuleitungskabeln und zum wasserdichten Abschluß des hinteren Endes der Glühlampenfassung ist die von der Platte und dem hinteren Endabschnitt des zylindrischen Teils des Fassungskörpers gebildete Schale mit Kleber gefüllt.To further increase the contact reliability between contact springs and Power supply cables and the watertight termination of the rear end of the bulb socket, the tray formed by the plate and the rear end portion of the cylindrical portion of the socket body is filled with adhesive.

Die Kontaktfedern (4, 5 und 6) sind an ihrem der Glühlampe abgewandten Endabschnitt (11, 12, 13) im Querschnitt U-förmig ausgeführt, mit dem sie durch eine ebenfalls U-förmig gestaltete Öffnung in der Platte (3) von der Glühlampenseite her soweit hindurchgeschoben werden, bis sie mit ihren Flächen (14, 15, 16) auf der Plattenfläche (17) aufliegen. In dieser Position wird die Fläche (17) der Platte von der aus dem Steg (18) des im Querschnitt U-förmigen Abschnitts (11, 12, 13) herausgebogenen, federnden Zunge hintergriffen. Damit sind die Kontaktfedern (4, 5, 6) in der Platte (3) festgesetzt.The contact springs (4, 5 and 6) are at their end facing away from the bulb (11, 12, 13) in cross-section U-shaped, with which they by a likewise U-shaped opening in the plate (3) from the incandescent side are pushed so far until they rest with their surfaces (14, 15, 16) on the plate surface (17). In this position, the surface (17) of the plate of the from the web (18) of the cross-sectionally U-shaped portion (11, 12, 13) bent out, resilient tongue engages behind. Thus, the contact springs (4, 5, 6) in the plate (3) fixed.

Um den Kontaktfedern (4, 5, 6) einen noch besseren und sichereren Halt in der Platte (3) zu geben, ist die Platte (3) mit zur Rückseite der Fassung weisenden, blockförmigen Vorsprüngen (20, 21, 22, 23) versehen, die den U-förmigen Endabschnitt (11, 12, 13) der Kontaktfedern (4, 5, 6) eng umfassen. Dazu sind die blockförmigen Vorsprünge (21, 22) mit Nuten versehen, in die die Enden (24, 25) der Schenkel (26, 27) der U-Form gleitend eingeschoben sind.In order to give the contact springs (4, 5, 6) an even better and safer hold in the plate (3), the plate (3) is provided with block-shaped projections (20, 21, 22, 23) facing the rear of the socket including the U-shaped end portion (11, 12, 13) the contact springs (4, 5, 6) tightly. For this purpose, the block-shaped projections (21, 22) are provided with grooves into which the ends (24, 25) of the legs (26, 27) of the U-shape are slidably inserted.

In die Schenkel (26, 27) des im Querschnitt U-förmigen Endabschnitts (11, 12, 13) der Kontaktfedern (4, 5, 6) sind die Schneidklemmschlitze (28, 29) zur Schneidklemmverbindung mit den Kabeln (30, 31, 32) eingebracht. Diese senkrecht zur Längsmittelachse des Fassungskörpers (1) verlaufenden Kabel (30, 31, 32) sind zur Zugentlastung in Schlitze eingequetscht, die in den hinteren Rand (33) des rückwärtigen Endes des hülsenförmigen Teils (2) des Fassungskörpers (1) eingebracht sind.In the legs (26, 27) of the cross-sectionally U-shaped end portion (11, 12, 13) of the contact springs (4, 5, 6) are the insulation displacement slots (28, 29) for insulation displacement connection with the cables (30, 31, 32 ) brought in.
