Definitions

  • the invention relates to a lighting device for vehicles, comprising a housing, with a light element carrying socket which is releasably secured to the edge region of an opening of the housing and carries second electrical contact elements, against which first electrical contact elements, and with a retaining ring, the carries first contact elements, surrounds the opening in the interior of the housing and engages with radially resilient latching elements in Verrastungsmarken the edge region of the opening of the housing.
  • the light element is an incandescent lamp, which is inserted with a socket in a socket.
  • the socket is inserted bayonet-like together with the light element from the outside of a housing forth in an opening of the housing and engages behind with radially projecting lugs the edge region of the opening, wherein the socket rests on the outside of the housing with a resilient sealing element at the edge region of the opening and pushes the lugs against the inner edge region of the opening.
  • resilient first contact elements are mounted, which bear resiliently against second contact elements.
  • the second contact elements are attached to electrical cables of a wiring harness, arranged in the interior of the housing and each inserted into a holding device of the housing.
  • the assembly is cumbersome and time-consuming and it may happen that the second contact elements are not securely fixed to the housing and can be detached from the housing or the second contact elements occupy an inaccurate position and no secure contact with the first contact elements of the socket out.
  • a lighting device for vehicles in which the second contact elements are attached to a retaining ring which surrounds the opening of the housing and is latched from the inside of the housing forth with with the edge region of the opening.
  • resilient locking elements of the retaining ring engage in Verrastungmarken the edge region of the opening.
  • the attached to the socket resilient contact elements are designed to be radially resilient and can bend during assembly of the version.
  • the object of the invention is to improve the lighting device for vehicles described in the preamble of claim 1 such that is ensured without additional control device that the first contact elements occupy their desired position to the socket.
  • This object is achieved according to the invention in that the distance between the locking elements of the retaining ring to the socket is smaller than the radial travel of the locking elements instagigen locking with the Verrastungsmarken.
  • the first contact elements have a precise position relative to the second contact elements of the socket, since the lamp socket can be produced with very close tolerances for a part securing the latching elements in their locking position and the retaining ring.
  • the socket can not be fixed to the housing, because then the not latched locking element far into the opening in the housing, that the socket is not inserted far enough into the opening or can not be brought into its locking position. In this case, the retaining ring can be pressed completely out of the housing through the socket.
  • the installation of the lighting device is simple and quick to carry out, since the already equipped with the first contact elements retaining ring is only to lock with the housing.
  • the retaining ring is fixed rattle-free in its mounting direction on the housing when resilient elements are integrally formed on the retaining ring or the edge region of the housing, which bear resiliently against a contact surface of the housing or the retaining ring and press the locking elements of the retaining ring against axial surfaces of the Verrastungsmarken.
  • the resilient elements of the retaining ring are formed by tongues whose roots are integrally formed on the bottom of a recess of the retaining ring and protrude with its free end of the recess.
  • the spring travel of the resilient elements is particularly large in the mounting direction of the retaining ring when the resilient elements protrude over most of their length laterally from the recess and extend at an acute angle to the mounting direction of the retaining ring.
  • the socket extends adjacent to the interior of the housing with a conically tapered lateral surface portion adjacent to the latching elements, wherein the latching elements extend in a äuqidistanten distance to the conical lateral surface portion of the socket.
  • the second contact elements are radially elastically yielding, as seen from the rear side of the illumination device are covered by the edge region of the opening and are arranged in the interior of the retaining ring.
  • the elastic second contact elements are arranged protected against damage before, during and after the mounting of the retaining ring.
  • the first contact elements are rigidly connected to the socket.
  • the retaining ring is easily latched to the housing and the locking elements are securely locked transversely to the mounting direction of the retaining ring when the elastic locking elements in the mounting direction of the retaining ring-facing arms which engage with locking lugs in the Verrastungsmarken, in a recess of the edge region of the opening of the housing are arranged.
  • a serving as lighting device for vehicles headlamp has an existing plastic cup-shaped housing 1, the front side is covered by a translucent cover plate, not shown.
  • an unillustrated light module for a low beam light and a flashing light is arranged in the interior of the cup-shaped housing 1.
  • the flashing light has a holding device 12 for a light element 2, which is an incandescent lamp on.
  • the light element 2 is inserted with a base 17 in a plastic version 3 existing.
  • the socket 3 is inserted together with the light element 2 from the back of the housing 1 forth in an opening 5 of the housing 1.
  • the frame 3 rests with a sealing ring 18 on an outer edge region 4 of the opening 5 and engages behind the edge region 4 with radially projecting lugs 19.
  • the socket 3 is fixed by means of a rotary closure to the edge region 4 of the opening 5.
  • the light element 2 protrudes with a glass bulb 20 into the interior of the housing 1.
  • electrical second contact elements 8 are mounted, which are designed to be largely rigid, in the insertion direction of the socket 3, the radially projecting lugs 19 are upstream and protected behind radially projecting projections 24 of the version 3 are arranged. As a result, the second contact elements 8 can not be damaged when mounting the socket 3.
  • first contact elements 7 are arranged protected from damage, which rest under prestress against the second contact elements 8 of the socket 3.
  • the first contact elements 7 are held firmly in receptacles 22 of the retaining ring 9.
  • the electrical leads 21 connected to the contact elements 7 and 8 are additionally supported in a receiving projection 23 of the retaining ring 9.
  • no vibrations of the electrical lines 21 can be transmitted to the second contact elements 8 when driving.
  • the retaining ring 9 is automatically fixed by means of locking elements 10 on Verrastungsmarken 11 of the edge portion 4 of the opening 5 of the housing 1.
  • latching elements 10 serve three in the mounting direction of the retaining ring 9 facing resilient arms, which have a locking lug 6 at the free end.
  • the locking elements 10 and the Verrastungsmarken 11 are arranged in a recess of the edge portion 4 of the opening 5.
  • the socket 3 adjoins the resilient latching elements 10 at a distance from a conical lateral surface section 16 that tapers in the direction of insertion. The distance between the locking elements 10 and the conical lateral surface portion 16 is smaller than the radial travel of the locking elements 10 instägtigen latching with the Verrastungsmarken 11.
  • the version 3 can with its conical Jacket surface portion 16 abut directly on one or more locking elements 10.
  • the retaining ring 9 rests with formed resilient elements 13 on the inside of the edge region 4 of the opening 5 of the housing 5 under prestress.
  • resilient elements 13 are tongues which are formed with its root at the bottom of a recess 15 and laterally projecting outwardly from the recess 15.
