Definitions

  • 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.
  • 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.
  • the 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.
  • 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
  • the Halt ⁇ ng 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.
  • the entire Retaining ring is designed to be resilient radially to the longitudinal axis.
  • 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
  • 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.
  • FIG. 1 shows a section along the line A-A in Figure 2 by a lamp holder of a headlight for vehicles
  • Figure 2 is a view from the direction X in Figure 1;
  • a 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.
  • 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).
  • 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)
  • 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
  • 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).
  • a stop not shown
  • 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.
  • 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).
  • 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) .
  • the edge regions ⁇ (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 .
  • 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).

Abstract

Ce porte-lampe comporte, pour loger une lampe (1), une bague de support (2) montée sur un réflecteur (3). La lampe est montée sur la bague de support dans le sens de son axe longitudinal. Un anneau de blocage (4) est monté sur la bague de support (2) et bloque la lampe (1) sur cette dernière dans le sens de son axe longitudinal et dans un sens radial par rapport à l'axe de lampe. Pour pouvoir bloquer la lampe radialement par rapport à son axe sur la bague de support, l'anneau de blocage (4) présente une surface d'appui (5) orientée radialement vers l'intérieur et appuyant la lampe (1) contre une surface de fixation (6) de la bague de support (2), orientée radialement vers l'intérieur. L'anneau de blocage (4) prend alors appui contre une surface de butée (7) de la bague de support, orientée radialement.
