Description

Die Erfindung betrifft einen Lampenhalter eines Scheinwerfers für Fahrzeuge gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a lamp holder of a headlamp for vehicles according to the preamble of claim 1.

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 Fassungsring 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 Haltering ist mittels eines Drehverschlusses 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 is from DE 34 25 291 A1 became known. The lamp holder is on a reflector of the Headlamp arranged and has a made of plastic Socket ring, which by means of a bayonet lock in an opening of the Reflector is fixed. In other known headlights for vehicles the mounting ring is made in one piece with the reflector. In the central opening a lamp with its glass bulb in front of the socket ring lies on a fixing surface of the Setting ring. A retaining ring placed on the mounting ring is by means of a twist lock is attached to the frame ring and lies with molded resilient elements under tension on the base and presses the base towards the direction of insertion of the lamp against the socket ring. So that Lamp also radially to its direction of insertion exactly to the holder ring and thus to Reflector is fixed, the lamp would have to be as in that from DE 28 53 227 A1 known lamp holder radially against a fixing surface of the socket ring be pressed. A spring element attached to the reflector is used separate spring element.

Aus der DE - C1 - 4436409 ist ein Scheinwerfer bekannt, bei dem der Haltering aus Federblech hergestellt ist und sich mit radial nach außen stehenden Haken an der Innenseite des Fassungsringes festkrallt. Dadurch ist der Haltering unlösbar an dem Fassungsring festgesetzt. Damit nach der Montage der Lampe der Haltering sicher an dem Fassungsring gehaltert ist, ist der Haltering zwischen dem Fassungsring und einem an dem Fassungsring lösbar befestigten Deckel eingespannt. Die Lampe ist durch den Haltering sowohl axial als auch radial arretiert. Hierbei ist es nachteilig, dass der Haltering erst durch einen zusätzlichen Deckel sicher an dem Fassungsring gehaltert ist.A headlight is known from DE - C1 - 4436409, in which the retaining ring is made of Spring plate is made and with radially outward hook on the Claws inside of the socket ring. This makes the retaining ring unsolvable on the Setting ring fixed. So that the retaining ring is secure after installing the lamp is held on the mounting ring, the retaining ring between the mounting ring and a lid releasably attached to the mounting ring. The lamp is locked axially and radially by the retaining ring. Here it is disadvantageous that the retaining ring is only securely attached to the mounting ring by an additional cover is supported.

Bei dem aus der DE - U- 9104169 bekannten Scheinwerfer weist ein am Reflektor befestigter Fassungsring ein federndes Element auf, das die Lampe radial fixiert. Zur sicheren Halterung der Lampe müsste diese durch ein zusätzliches Halteteil an dem Fassungsring befestigt werden.In the headlight known from DE-U-9104169, one has on the reflector attached lampholder on a resilient element that fixes the lamp radially. to the lamp should be securely held by an additional holding part on the Mount ring to be attached.

Ferner ist aus der DE - A1 - 4123379 ein Lampenhalter eines Scheinwerfers bekannt, bei dem ein Deckel als Haltering dient, der bajonettartig auf den Fassungsring aufgesetzt ist und mit angeformten federnden Elementen unter Vorspannung an dem Sockel anliegt. Der Haltering drückt den Sockel in Richtung der Einsetzrichtung der Lampe gegen den Fassungsring.Furthermore, DE-A1-4123379 describes a lamp holder for a headlight is known, in which a lid serves as a retaining ring, the bayonet-like on the Mount ring is put on and with molded resilient elements underneath Bias is applied to the base. The retaining ring pushes the base towards the Direction of insertion of the lamp against the holder ring.

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 Längsachse der Lampe an dem Fassungsring des Reflektors fixierbar ist. Diese Aufgabe wird nach der Erfindung durch die Merkmale des Anspruchs 1 gelöst.The object of the invention is that described in the preamble of claim 1 To design lamp holder of a headlight for vehicles such that the Lamp without having to use an additional separate part, both in Direction of the longitudinal axis of the lamp as well as in a radial direction Longitudinal axis of the lamp can be fixed to the holder ring of the reflector. This The object is achieved according to the invention by the features of claim 1 solved.

Hält der Haltering die Lampe sowohl gegen eine entgegen der Aufsetzrichtung des Halteringes gerichtete Fixierungsfläche des Fassungsringes als auch gegen die radial nach innen gerichtete Fixierungsfläche des Fassungsringes, so ist die Lampe sehr genau zu einer Reflexionsfläche des Reflektors focussiert. Die Montage des Halteringes ist leichtgängig und die radiale Fixierung der Lampe ist sicher, wenn an den Haltering ein die Anlagefläche aufweisendes Federelement angeformt ist, welches die Lampe gegen die Fixierungsfläche des Fassungsringes drückt.The retaining ring holds the lamp both against the opposite direction of attachment Retaining ring directed fixation surface of the socket ring as well as against The lamp is the radially inward-facing fixing surface of the holder ring focused very precisely to a reflection surface of the reflector. The assembly of the Retaining ring is smooth and the radial fixation of the lamp is secure when on the retaining ring is molded onto a spring element which has the contact surface, which presses the lamp against the fixing surface of the holder ring.

Weiterhin ist es zweckmäßig, wenn der gesamte Haltering radial zur Längsachse elastisch nachgiebig ausgeführt ist. Dadurch ist der Haltering selbst ein Federelement und liegt mit seiner Anlagefläche unter Vorspannung an der Lampe und an der Widerlagerfläche des Fassungsringes an.Furthermore, it is expedient if the entire retaining ring is radial Longitudinal axis is designed to be resilient. This makes the retaining ring itself a Spring element and lies with its contact surface under tension on the lamp and on the abutment surface of the mounting ring.

Der Haltering ist in seiner Endstellung gegen ungewolltes Lösen gehalten, wenn die Widerlagerfläche des Fassungsringes zusammen mit einem an der Widerlagerfläche sich abstützenden Flächenabschnitt des Halteringes eine Rastvorrichtung bildet, welche aus einer Verrastungsmulde und einem in die Verrastungsmulde selbsttätig eingreifenden Verrastungsansatz besteht. Ein ungewolltes Lösen des Halteringes aus seiner Endstellung ist nicht möglich, wenn in den Verrastungsansatz eine Befestigungsöffnung für ein Befestigungsmittel angebracht ist, das in eine Freimachung des Halteringes bzw. Fassungsringes eingreift. Dadurch muß vor einem Losdrehen des Halteringes das Arretierungsmittel gelöst werden.The retaining ring is in his End position held against unwanted loosening when the abutment surface of the Socket ring together with a support on the abutment surface Surface section of the retaining ring forms a locking device which consists of a Locking trough and an automatically engaging in the locking trough Latching approach exists. An unwanted loosening of the retaining ring from it End position is not possible if a Fastening opening for a fastener is attached, which in a Clearance of the retaining ring or lampholder engages. This must be done before the locking means can be released by unscrewing the retaining ring.

Das erhabene Fixierungsmittel (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 verläuft 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 Randbereiche (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 Haltering (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 Fixierungsfläche (6) gehalten ist. The radial holding of the lamp (1) against the fixing surface (6) of the Socket ring (2) can both through the contact surface (5) of the retaining ring (4) and / or by the raised fixing means (20) of the mounting ring (2) respectively. The raised fixing means (20) is used for radial locking of the Base (17) of the lamp (1) when the raised fixing means (20) with the side surfaces facing away (30) converging to the bottom of the recess (19) or extends to the longitudinal axis of the lamp (1) and with the side surfaces (30) the outer lateral edge regions (31) of the recess (19) are adjacent. At a rectangular recess (19) of the base (17) of the lamp (1) are the Edge areas (31) formed by the outer edges of the recess (19), which run parallel to the longitudinal axis of the lamp (1) and line to the Lateral surfaces (30) of the fixing means (20) rest. The sublime Connecting means (20) is slight across its wide side surfaces (30) resilient when the raised fixation means (20) from two to the Socket ring (2) molded ribs, which on the opposite Pages that have side surfaces (30). Serves for the radial locking of the lamp (1) on the mounting ring (2) both the raised fixing means (20) and the Retaining ring (4), so even with a little play between the side surfaces (30) of the raised fixing means (20) and the edge areas (31) of the recess (19) of the lamp (1), make sure that the lamp (1) against the of the lugs (21) formed fixation surface (6) is held.
