Definitions

  • the invention relates to a socket according to the preamble of patent claim 1, a lamp provided with such a socket according to the preamble of patent claim 15.
  • the base according to the invention can in principle be used in a large number of single-ended lamps.
  • the main application of the socket is likely to be in lamps for vehicle headlights, which are inserted through a pinch on one side in a socket.
  • a lamp with such a base for example, in the post-published application DE 10 2004 007 150 the applicant described.
  • a base with a metallic base part for receiving the lamp is used.
  • This metallic base part is inserted into a second approximately cup-shaped plastic base part, which is provided with two contact springs. These are used for electrical contacting of the lamp and are integrated by means of injection molding in the second plastic base part.
  • On lamp-side end portions of the contact springs On lamp-side end portions of the contact springs, a groove-shaped recess for receiving current leads of the lamp is formed in each case.
  • the power supply lines are inserted into the recesses of the contact springs and fixed by means of a weld.
  • the disadvantage of such lamps is, on the one hand, that an additional base part is required to hold the lamp and, on the other hand, the joining technique between the lamp and the contact springs requires a high production outlay due to the welding.
  • the invention has for its object to provide a base for a lamp, in particular for a vehicle lamp, provided with such a base lamp and a method for producing such a lamp, in which compared to conventional solutions a simplified production with minimal device complexity and a improved mounting of the lamp is made possible on the base.
  • the base according to the invention for a lamp in particular for a vehicle lamp, has a base housing and at least two contact elements fixed in the base housing for receiving and electrically contacting the lamp.
  • the contact elements of the base housing are fixed positively and / or non-positively by means of a base slide which can be fixed in the base housing.
  • the contact springs can be designed with a holding region for receiving and making electrical contact with the lamp, so that the holder of the lamp in the base in relation to the prior art according to FIG DE 10 2004 007 150 is significantly improved.
  • This solution enables a simplified installation of the lamp in the base and a much simplified compared to the generic method production, since the separate steps to form the weld can be omitted.
  • the base slide is preferably a socket part which can be inserted into the socket housing and serves to fix the electrical contact elements after insertion into the socket housing.
  • the base slide is radially insertable into a receiving portion of the base housing.
  • the base slide with the base housing at least partially forms a common base and / or side surface. Due to the socket which is closed off via the base slide, the penetration of moisture and dirt into the base housing is effectively prevented and the service life of the lamp is substantially increased.
  • the base slide on a plurality of projections which are insertable into recesses of the base housing.
  • the projections facilitate the insertion of the base slide in the base housing.
  • the recesses of the base housing form as longitudinal grooves which extend at right angles to a longitudinal axis of the base housing.
  • At least two longitudinal grooves are formed with a larger cross-section than the other longitudinal grooves.
  • the base slide is preferably fixed to the base housing via a locking element.
  • the locking element has at least one latching lug. Since the base slide for mounting the contact elements in the base housing is inserted only radially into this, simplifies the production of the socket considerably (so-called one-touch solution).
  • the base housing preferably has at least two recesses for receiving the contact elements, which are arranged such that the contact elements are substantially parallel to one another.
  • the recesses are arranged in the socket housing such that the contact springs are fixed between the socket slide and the socket housing. This facilitates the mounting of the lamp in the socket.
  • contact springs use whose spring legs are preferably angled to each other.
  • the base slide has a substantially slot-shaped recess for receiving a spring leg of the first contact spring and a contact surface for a spring leg of the second contact spring.
  • the contact springs preferably have at least one spring leg, which is non-positively and / or positively engageable with the lamp.
  • the base via a substantially annular flange with a headlight, in particular a vehicle headlight, directly or indirectly brought into abutment.
  • a sealing element for example a sealing washer, may be arranged between the flange and the headlight housing.
  • the sealing element may also be provided a spring element, for example made of metal, or a retaining ring for bridging tolerances of the headlamp.
  • the base housing is rotatable relative to the headlight and releasably secured by means of bayonet lock on this. This allows easy mounting of the lamp to the vehicle headlight.
  • the base housing and / or the base slide of an electrically insulating material, preferably of a plastic.
  • the region of the base arranged close to the lamp vessel can consist of a high-temperature plastic and the thermally less heavily loaded base slide can be made of a less expensive plastic.
  • the lamp according to the invention has a base and contact elements, which are fixed by means of the base slide in the base housing positively and / or non-positively.
  • the socket according to the invention is by no means limited to such lamp types.
  • FIG. 1 shows a three-dimensional representation of a base 1 according to the invention with a used in this lamp 2 type W16W, as used for example in a vehicle headlight as a flashing or brake light lamp.
  • a lamp 2 has a connected to power supply lamps (not shown), which is inserted into a lamp vessel 4 made of quartz glass.

  • This has a base housing 8, the lamp side has a mounting recess 10 for receiving the lamp 2 in the base housing 8.
  • the base housing 8 two as contact springs 12, 14 executed contact elements are arranged in the region of the mounting recess 10 of the lamp 2 form a holding portion 16 for receiving the pinch seal 6 of the lamp 2 and each electrically contacted with one of the two power supply lines of the lamp (not shown).
  • the base housing 8 has a substantially cylindrical fastening portion 18 on the lamp side, on whose outer peripheral surface 20 has three radially projecting approximately web-shaped connecting elements 22 (in FIG. 1 one of the connecting elements 22 is covered by the mounting portion 18) are formed, which engage in corresponding holding elements of a headlamp and are fixed there (not shown).
  • the attachment portion 18 merges on the side facing away from the lamp vessel in an at least partially annular flange 24.
  • the sealing disc 28 is disposed in the assembled state of the base 1 between the flange 24 and headlights and prevents the ingress of moisture and dirt in the headlight.
  • the base housing 8 goes beyond the flange 24 on the side facing away from the lamp vessel in a substantially box-shaped handle member 30 via.
  • the base 1 For mounting the base 1 on the headlamp this is inserted via the attachment portion 18 in the headlight and fixed by means of the connecting elements 22 by a rotational movement relative to the headlight on this - in other words - the connecting elements 22 form with the holding elements of the headlamp from a bayonet lock, about the base 1 is releasably secured to the headlight.
  • the insertion of the base 1 in the headlight is facilitated by a frontally formed on the mounting portion 18 chamfer 32.
  • FIG. 2 representing a three-dimensional detail of the base 1
