Beschreibungdescription
Lampenhalter eines Scheinwerfers für FahrzeugeLamp holder of a headlight for vehicles
Die Erfindung betrifft einen Lampenhalter eines Scheinwerfers für Fahrzeuge, mit einem zur Aufnahme einer Lampe dienenden Fassungsring eines Reflektors und mit einem auf den Fassungsring aufsetzbaren Haltering, welcher die Lampe in Richtung ihrer Längsachse an dem Fassungsring arretiert.The invention relates to a lamp holder of a headlight for vehicles, with a mounting ring for a reflector for receiving a lamp and with a mounting ring which can be placed on the mounting ring and which locks the lamp in the direction of its longitudinal axis on the mounting ring.
Ein solcher Lampenhalter eines Scheinwerfers für Fahrzeuge ist aus der DE 34 25 291 A1 bekannt geworden. Der Lampenhalter ist an einem Reflektor des Scheinwerfers angeordnet und weist einen aus Kunststoff hergestellten Fassungsring auf, welcher mittels eines Bajonettverschlusses in einer Öffnung des Reflektors festgesetzt ist. Bei anderen bekannten Scheinwerfern für Fahrzeuge ist der Fassungsπng einstückig mit dem Reflektor ausgeführt. In die zentrale Öffnung des Fassungsringes ist eine Lampe mit ihrem Glaskolben voraus eingesetzt und liegt an einer entgegen der Einsetzrichtung gerichteten Fixierungsfläche des Fassungsringes an. Ein auf den Fassungsring aufgesetzter Halteπng ist mittels eines Drehverschiusses an dem Fassungsring festgesetzt und liegt mit angeformten federnden Elementen unter Vorspannung an dem Sockel an und drückt den Sockel in Richtung der Einsetzrichtung der Lampe gegen den Fassungsring. Damit die Lampe auch radial zu ihrer Einsetzrichtung genau zum Fassungsring und somit zum Reflektor fixiert ist, müßte die Lampe wie bei dem aus der DE 28 53 227 A1 bekannten Lampenhalter radial gegen eine Fixierungsfläche des Fassungsringes gedrückt werden. Als federndes Element dient ein an dem Reflektor befestigtes separates Federelement.Such a lamp holder of a headlight for vehicles has become known from DE 34 25 291 A1. The lamp holder is arranged on a reflector of the headlight and has a holder ring made of plastic, which is fixed in an opening of the reflector by means of a bayonet catch. In other known headlights for vehicles, the version is made in one piece with the reflector. A lamp with its glass bulb is inserted into the central opening of the holder ring and bears against a fixing surface of the holder ring that is directed against the direction of insertion. A holder placed on the holder ring is fixed by means of a rotary lock on the holder ring and rests with molded resilient elements against the base and presses the base in the direction of insertion of the lamp against the holder ring. So that the lamp is also fixed radially to its direction of insertion exactly to the holder ring and thus to the reflector, the lamp would have to be pressed radially against a fixing surface of the holder ring, as in the lamp holder known from DE 28 53 227 A1. A separate spring element attached to the reflector serves as the spring element.
Aufgabe der Erfindung ist es, den im Oberbegriff des Anspruchs 1 beschriebenen Lampenhalter eines Scheinwerfers für Fahrzeuge derart zu gestalten, daß die Lampe, ohne ein zusätzliches separates Teil verwenden zu müssen, sowohl in Richtung der Längsachse der Lampe als auch in einer radialen Richtung zur Langsachse der Lampe an dem Fassungsring des Reflektors fixierbar ist Diese Aufgabe wird nach der Erfindung durch die Merkmale des Anspruchs 1 und des Anspruchs 11 jeweils allein oder zusammen gelostThe object of the invention is to design the lamp holder of a headlight for vehicles described in the preamble of claim 1 such that the lamp, without having to use an additional separate part, both in the direction of the longitudinal axis of the lamp and in a radial direction Longitudinal axis of the lamp can be fixed to the socket ring of the reflector. This object is achieved according to the invention by the features of claims 1 and 11, either alone or together
Halt der Haltering die Lampe sowohl gegen eine entgegen der Aufsetzrichtung des Halteringes gerichtete Fixierungsflache des Fassungsπnges als auch gegen die radial nach innen gerichtete Fixierungsflache des Fassungsringes, so ist die Lampe sehr genau zu einer Reflexioπsflache des Reflektors focussiert Die Montage des Halteπnges ist leichtgangig und die radiale Fixierung der Lampe ist sicher, wenn an den Haltering ein die Anlageflache aufweisendes Federelement aπgeformt ist, welches die Lampe gegen die Fixierungsflache des Fassungsπnges drucktIf the retaining ring holds the lamp both against a fixing surface of the socket ring directed against the mounting direction of the holder ring and against the fixing surface of the holder ring directed radially inwards, the lamp is focused very precisely to a reflecting surface of the reflector. The mounting of the holding rod is smooth and the radial Fixing the lamp is secure if a spring element having the contact surface is formed on the retaining ring, which presses the lamp against the fixing surface of the socket
Der Halteπng ist einfach aufgebaut, wenn er an seinem inneren Randbereich die Anlageflache aufweist und sich mit seinem äußeren Randbereich an der Widerlagerflache abstutzt, welche an dem äußeren Randbereich des Fassungsπnges angebracht und radial nach außen gerichtet ist In diesem Zusammenhang ist es zweckmäßig, wenn der gesamte Haltering radial zur Langsachse elastisch nachgiebig ausgeführt ist Dadurch ist der Haiteπng seibst ein Federelement und liegt mit seiner Anlageflache unter Vorspannung an der Lampe und an der Widerlagerflache des Fassungsringes anThe Haltπng is simple if it has the contact surface on its inner edge region and is supported with its outer edge region on the abutment surface, which is attached to the outer edge region of the socket and is directed radially outwards. In this context, it is expedient if the entire Retaining ring is designed to be resilient radially to the longitudinal axis. As a result, the retainer is itself a spring element and rests with its contact surface under prestress on the lamp and on the abutment surface of the holder ring
Der Halteπng ist einfach und schnell an dem Fassungsπng festsetzbar und von dem Fassungsring losbar, wenn der Halteπng durch einen zwischen Halte- und Fassungsring bestehenden Drehverschluß in eine Endstellung drehbar ist Als Drehverschluß kann ein Bajonettverschluß dienen Der Haltering ist in seiner Endstellung gegen ungewolltes Losen gehalten, wenn die Widerlagerflache des Fassungsπnges zusammen mit einem an der Widerlagerflache sich abstutzenden Flachenabschnitt des Halteringes eine Rastvorπchtung bildet, welche aus einer Verrastungsmulde und einem in die Verrastungsmulde selbsttätig eingreifenden Verrastungsansatz besteht. Ein ungewolltes Losen des Halteringes aus seiner Endstellung ist nicht möglich, wenn in den Verrastungsansatz eine Befestigungsoffnung für ein Befestigungsmittel angebracht ist, das in eine Freimachung des Halteringes bzw Fassuπgsπnges eingreift. Dadurch muß vor einem Losdrehen des Halteringes das Arretierungsmittel gelbst werden.The holder can be fixed quickly and easily to the holder and can be detached from the holder ring if the holder can be rotated into an end position by means of a rotary lock between the holder and holder ring. A bayonet lock can serve as the rotary lock. when the abutment surface of the socket together with a flat portion of the retaining ring which is supported on the abutment surface forms a locking device which consists of a locking trough and a locking lug which engages automatically in the locking trough. An unwanted loosening of the retaining ring from its end position is not possible if a fastening opening for a fastener is attached in the latching approach Clearance of the retaining ring or Fassuπgsπnges intervenes. As a result, the locking means must be yellow before loosening the retaining ring.
Der Haltering ist leichtgängig in seine Endstellung zu drehen, wenn entweder die Widerlagerfläche des Fassungsringes und/oder ein an der Widerlagerfläche sich abstützender Flächenabschnitt des Halteriπges eine schräg verlaufende Gleitfläche aufweist, durch welche der Halteπng beim Verdrehen in seine Endsteiluπg mit seiner Anlagefläche zur Fixierungsfläche des Fassungsringes hin bewegbar ist. Hierbei muß der Haltering mit radialem Spiel auf den Fassungsring aufsetzbar sein, damit sich dieser beim Verdrehen in seine Endstellung zur Fixierungsfläche des Fassungsringes hin bewegen kannThe retaining ring can be rotated smoothly into its end position if either the abutment surface of the mounting ring and / or a surface section of the retaining ring that is supported on the abutment surface has an obliquely running sliding surface, through which the retaining ring, when turned into its end part, with its contact surface to the fixing surface of the mounting ring is movable. In this case, the retaining ring must be able to be placed on the mounting ring with radial play, so that it can move towards the fixing surface of the mounting ring when it is rotated into its end position

Von der Rückseite des Reflektors (3) her ist in die Öffnung (14) des Reflektors (3) bzw des Fassungsringes (2) eine Lampe (1 ), welches eine Gasentladungslampe ist, eingesetzt. Die Lampe ( 1 ) liegt mit einem umlaufenden Flansch (16) ihres Sockels (17) an einer entgegen der Einsetzrichtung der Lampe (1 ) gerichteten Fixierungsfläche (18) des Fassungsπnges (2) liegt. In den Flansch (16) des Sockels (17) der Lampe (1 ) ist eine Aussparung (19) eingebracht, in welche ein erhabenes Fixierungsmittel (20) des Fassungsringes (2) eingreift. Das Fixierungsmittel (20) ist in Anbaulage des Reflektors (3) im oberen Bereich des Fassungsringes (2) angeordnet. Der Fassungsring (2) weist in seinem unteren Bereich eine nach oben hin gerichtete Fixierungsfläche (6) auf, an welcher der Flansch (16) des Sockels (17) mit seiner äußeren schmalen Seitenfläche anliegt. Die Fixierungsfläche (6) ist von zwei an den Fassungsring (2) angeformten AnsätzenA bowl-shaped reflector (3) made of plastic is adjustably arranged in a headlight housing (not shown). The reflector has an opening (14) in the apex area, which is surrounded on the back of the reflector by a reflector neck (15) molded onto the reflector (3) and a mounting ring (2) formed on the outer edge of the reflector neck (15), which is surrounded by the reflector neck (15) is directed radially outwards. From the back of the reflector (3) there is one in the opening (14) of the reflector (3) or the mounting ring (2) Lamp (1), which is a gas discharge lamp, is used. The lamp (1) lies with a circumferential flange (16) of its base (17) on a fixing surface (18) of the socket (2) directed counter to the direction of insertion of the lamp (1). A recess (19) is made in the flange (16) of the base (17) of the lamp (1), into which a raised fixing means (20) of the holder ring (2) engages. The fixing means (20) is arranged in the mounting position of the reflector (3) in the upper region of the mounting ring (2). In its lower region, the mounting ring (2) has an upwardly directed fixing surface (6), against which the flange (16) of the base (17) lies with its outer narrow side surface. The fixing surface (6) is formed by two lugs molded onto the mounting ring (2)
(21 ) gebildet, welche voneinander beabstandet sind und in Lichtaustrittsrichtung zu einer vertikale Mittelebene des Reflektors (3) symmetrisch angeordnet sind. Die Lampe (1 ) ist durch einen auf den Fassungsring (2) aufgesetzten Haltering (4) an dem Fassungsπng (2) gehaltert. Der Haltering (4) ist aus einem elastisch nachgiebigen Kunststoff hergestellt und weist einen in seiner Aufsetzrichtung weisenden äußeren umlaufenden Randabschnitt (22) auf. Der Haltering (4) ist mittels eines bajonettartigen Drehverschlusses an dem Fassungsring (2) festgesetzt. Der Drehverschiuß ist gebildet durch an die Innenseite des äußeren Randabschnitts(21) are formed, which are spaced apart and are arranged symmetrically in the light exit direction to a vertical center plane of the reflector (3). The lamp (1) is held on the frame (2) by a retaining ring (4) placed on the frame ring (2). The retaining ring (4) is made of an elastically resilient plastic and has an outer peripheral edge section (22) pointing in the direction in which it is attached. The retaining ring (4) is fixed to the mounting ring (2) by means of a bayonet-type twist lock. The twist lock is formed by on the inside of the outer edge portion
(22) angeformten Vorsprüngen (23), welche durch entsprechende Aussparungen des Fassungsringes (2) hindurchführbar sind und nach einem Verdrehen des Halteringes (4) den Fassungsring (2) hiπtergreifen. Der Haltering (22) ist mit einem Ansatz (23) bis gegen einen an den Reflektor (3) angeformten Anschlag (nicht dargestellt) in seine Endstellung drehbar. An den rückwärtigen Rand des umlaufenden Randabschnitts (22) des Halteπnges (4) sind drei radial nach innen gerichtete federnde Elemente (24) angeformt, welche unter Vorspannung an dem Flansch (16) des Sockels (17) der Lampe (1 ) anliegen und den Flansch (16) gegen die von Warzen des Fassungsringes (2) gebildete Fixierungsflache (18) drücken Der Haltering (4) weist oben am inneren Randbereich eine nach unten gerichtete Erhöhung (25) mit einer Anlagefläche (5) auf, welche an der Mantelflache des Sockels (17) der Lampe (1 ) anliegt und den Flansch (16) gegen die Fixierungsfläche (6) der beiden Ansätze (21 ) hält. Dabei stützt sich der Halteπng (4) mit einem Flächenabschnitt (9) der Innenseite des Randabschπitts (21 ) an einer radial nach außen gerichteten Widerlagerfläche (7) des Fassungsππges (2) ab. Der Fassungsrmg (2) drückt mit seiner Anlageflache (5) gegen den Sockel (17) der Lampe (1 ), da der Haltering (1 ) quer zu seiner Aufsetzrichtung elastisch nachgiebig ausgeführt ist. Als Widerlagerfläche (7) dient die Mantelfläche eines hülsenfόrmigen Verrastungsansatzes (26), welcher in einer von der Widerlagerfläche (7) gebildeten Verrastungsmulde des Randabschnitts (22) des Halteringes (4) eingreift. Beim Aufsetzen des Halteringes (4) auf den Fassungsring (2) taucht der hülsenformige Verrastungsansatz (26) spielfrei in eine Vertiefung (27) in der Innenseite des Randabschnitts (22) des Halteringes (4) ein. Beim Verdrehen des Halteringes (4) im Uhrzeigersinn gleitet der hülsenformige Verrastungsansatz (26) mit seiner Mantelfläche an einer Gleitfläche (13) des Flächenabschnitts (9) des Halteringes (4) entlang bis der hülsenformige Verrastungsansatz (26) selbsttätig in die von der Widerlagerfläche (7) gebildete Verrastungsmulde eingreift. In dieser Endstellung des Halteringes (4) kann der Haltering gegen ein ungewolltes Losen gesichert werden, indem in den hülseπfόrmigen Verrastungsansatz (26) eine als Arretierungsmittel (11 ) dienende Befestigungsschraube eingebracht wird. Dabei ragt der Kopf der Befestigungsschraube in eine Freimachung (12) des Halteringes (4) hinein. Die federnden Elemente (24) weisen Durchbrüche (28) auf, durch welche hindurch die Innenseite der Vorsprünge (23) entformbar ist. An dem Sockel (17) der Lampe (1 ) ist mittels eines nicht dargestellten Renkverschlusses ein elektrischer Anschlußstecker (29) befestigt.(22) molded projections (23) which can be passed through corresponding recesses in the mounting ring (2) and reach behind the mounting ring (2) after twisting the retaining ring (4). The retaining ring (22) can be rotated into its end position with a shoulder (23) up to a stop (not shown) formed on the reflector (3). At the rear edge of the peripheral edge portion (22) of the holding ring (4) three radially inwardly directed resilient elements (24) are formed, which bear under prestress on the flange (16) of the base (17) of the lamp (1) and Press the flange (16) against the fixing surface (18) formed by the warts of the mounting ring (2). The retaining ring (4) has a downward elevation (25) on the inner edge area with a contact surface (5) which is attached to the outer surface of the Base (17) of the lamp (1) abuts and holds the flange (16) against the fixing surface (6) of the two lugs (21). The support (4) is supported with a surface section (9) on the inside of the edge section (21) on a radially outward-facing abutment surface (7) of the holder (2). The Version (2) presses with its contact surface (5) against the base (17) of the lamp (1), since the retaining ring (1) is designed to be elastically flexible transversely to its mounting direction. The outer surface of a sleeve-shaped latching shoulder (26) serves as the abutment surface (7), which engages in a latching recess of the edge section (22) of the retaining ring (4) formed by the abutment surface (7). When the retaining ring (4) is placed on the mounting ring (2), the sleeve-shaped latching projection (26) dips into a recess (27) in the inside of the edge section (22) of the retaining ring (4) without play. When turning the retaining ring (4) clockwise, the sleeve-shaped latching attachment (26) slides with its outer surface along a sliding surface (13) of the surface section (9) of the retaining ring (4) until the sleeve-shaped latching attachment (26) automatically into the abutment surface ( 7) engages formed locking recess. In this end position of the retaining ring (4), the retaining ring can be secured against unwanted loosening by inserting a fastening screw serving as a locking means (11) into the sleeve-shaped latching attachment (26). The head of the fastening screw protrudes into an opening (12) in the retaining ring (4). The resilient elements (24) have openings (28) through which the inside of the projections (23) can be removed. An electrical connector (29) is attached to the base (17) of the lamp (1) by means of a bayonet lock (not shown).
Ist der gesamte Halteπng (4) weitestgeheπd starr ausgeführt, so ist es vorteilhaft, wenn die Anlageflache (5) des Halteππges (4) von einem an den Halteπng (4) angeformten fingerartigen Federelement gebildet ist, welches in Drehrichtung des Halteringes (4) verläuft.If the entire holder (4) is rigid as far as possible, it is advantageous if the contact surface (5) of the holder (4) is formed by a finger-like spring element which is molded onto the holder (4) and runs in the direction of rotation of the holding ring (4) .
Das radiale Halten der Lampe (1 ) gegen die Fixierungsflache (6) des Fassungsringes (2) kann sowohl durch die Anlagefläche (5) des Halteringes (4) und/-oder durch das erhabene Fixierungsmittel (20) des Fassungsπnges (2) erfolgen. Das erhabene Fixterungsmittel (20) dient zur radialen Arretierung des Sockels (17) der Lampe (1 ), wenn das erhabene Fixierungsmittel (20) mit den sich abgewandten Seitenflächen (30) konvergierend zum Grund der Aussparung (19) bzw. zur Längsachse der Lampe ( 1 ) hin verlauft und mit den Seitenflächen (30) an die äußeren seitlichen Randbereiche (31 ) der Aussparung (19) angrenzt. Bei einer rechteckförmigen Aussparung (19) des Sockels (17) der Lampe (1 ) sind die Randbereichθ (31 ) von den äußeren Kanten der Aussparung (19) gebildet, welche parallel zur Längsachse der Lampe (1 ) verlaufen und linienförmig an den Seitenflächen (30) des Fixierungsmittels (20) anliegen. Das erhabene Verbindungsmittel (20) ist quer zu seinen breiten Seitenflächen (30) geringfügig elastisch nachgiebig, wenn das erhabene Fixierungsmittel (20) aus zwei an den Fassungsring (2) angeformten Rippen besteht, welche auf den sich abgewandten Seiten die Seitenflächen (30) aufweisen. Dient zur radialen Arretierung der Lampe (1 ) an dem Fassungsring (2) sowohl das erhabene Fixierungsmittel (20) als auch der Halteππg (4), so ist auch bei einem kleinen Spiel zwischen den Seitenflächen (30) des erhabenen Fixierungsmittels (20) und den Randbereichen (31 ) der Aussparung ( 19) der Lampe ( 1 ) sicher, daß die Lampe ( 1 ) gegen die von den Ansätzen (21 ) gebildete Fixierungsflache (6) gehalten ist. The lamp (1) can be held radially against the fixing surface (6) of the holder ring (2) both by the contact surface (5) of the holder ring (4) and / or by the raised fixing means (20) of the holder ring (2). The raised fixing means (20) serves to radially lock the base (17) of the lamp (1) when the raised fixing means (20) converges with the side surfaces (30) facing away from the base of the recess (19) or the longitudinal axis of the lamp (1) runs and with the side surfaces (30) the outer lateral edge regions (31) of the recess (19) are adjacent. In the case of a rectangular recess (19) in the base (17) of the lamp (1), the edge regions θ (31) are formed by the outer edges of the recess (19), which run parallel to the longitudinal axis of the lamp (1) and are linear on the side surfaces ( 30) of the fixative (20). The raised connecting means (20) is slightly elastically flexible transversely to its wide side surfaces (30) if the raised fixing means (20) consists of two ribs molded onto the mounting ring (2), which have the side surfaces (30) on the sides facing away from them . If both the raised fixation means (20) and the retainer (4) are used for the radial locking of the lamp (1) on the holder ring (2), there is also a small clearance between the side surfaces (30) of the raised fixation means (20) and the edge regions (31) of the recess (19) of the lamp (1) ensure that the lamp (1) is held against the fixing surface (6) formed by the projections (21).
