Definitions
- the invention is based on an electrical contacting of a light source according to the preamble of patent claim 1.
- Such electrical contacting is known from DE 38 31 371 AI.
- the light source is an incandescent lamp of the type Hl inserted into a reflector of a headlight for vehicles.
- This light source has a contact pin which serves for the electrical connection of the light source to the positive pole of a voltage source.
- the light source has a base via which the light source is grounded.
- a plug part is placed on its contact pin postponed.
- a metallic mounting bracket engages, through which the light source is held on the reflector, and this mounting bracket has a plug contact, onto which a further plug part can be pushed, which establishes a ground connection of the light source.
- two separate plug parts must therefore be installed here, which means a great deal of work.
- the inventive electrical contacting of a light source with the features according to patent claim 1 has the advantage that only one plug part needs to be installed, through which the connection of the light source with the positive pole of the voltage source and the mass connection is established.
- FIG. 1 shows a detail of a lighting device for vehicles in a longitudinal section with a 2 shows the light source and the plug part from FIG. 1 in an enlarged illustration and FIG. 3 shows the plug part in a section along the line III-III in FIG. 2.
- FIG. 1 shows a lighting device for vehicles, which is a headlight but can also be a lamp or the like.
- the headlight has a reflector 10 with an opening 12 into which a light source 14 is inserted.
- the light source 14 is an incandescent lamp, in particular of the Hl type, and has an incandescent lamp as a luminous element.
- the light source 14 is held, for example, by means of a spring clip 16 on the reflector 10, which acts on the base plate 18 of the light source 14.
- the light source 14 has a contact pin 20 on the front end of its base pointing away from the reflector 10 as a contact element, which pin serves for connection to the positive pole of a voltage source.
- a bore 21 or a recess is provided in the contact pin 20.
- the light source 14 is grounded via its metallic base plate 18 or a metallic, approximately cuboid or cylinder-shaped base portion 22 connected to it. Between the metallic base portion 22 and the contact pin 20 there is a portion 24 made of electrically insulating material, the Diameter is slightly smaller than that of the base section 22.
- a plug part 30 is provided, which can be pushed onto the contact pin 20 of the light source 14 in the direction of the arrow 31.
- the Plug part 30 is shown in detail in FIG. 2.
- the plug part 30 has a plug-in sleeve 32 as a plug-in element, which is connected via an electrical line 34 to the positive pole of a voltage source, in the exemplary embodiment of the vehicle's on-board battery, via a light switch.
- the plug-in sleeve 32 has a resilient projection 33 projecting inwards from it, which cooperates with the bore 21 in the contact pin 20.
- the plug part 30 has an electrically insulating sheath 36, which has a section 38 surrounding the plug sleeve 32 and a section 40 surrounding the connector of the electrical line 34.
- the line 34 can emerge approximately coaxially to the mounting direction 31 of the plug part 30 or transversely to the plug part 30.
- the section 38 of the casing 36 surrounding the plug-in sleeve 32 is rectangular in cross section to the mounting direction 31 of the plug part 30 and has a wall 42 on its front end facing the light source 14, in which an opening 44 for the passage of the contact pin 20 of the light source 14 is present.
- the cross section of the opening 44 is adapted to that of the contact pin 20 so that the contact pin 20 passes through the opening 44 with little play transversely to the mounting direction 31 of the plug part 30.
- the plug-in sleeve 32 is fixed inside the casing 38 in a manner not shown.
- the plug part 30 can also be designed to achieve a so-called positive lock function.
- the end of the plug-in sleeve 32 facing the light source 14 is arranged at a distance from the wall 42 of the casing 38.
- a nose 45 protrudes from the inside of the casing 38 toward the plug-in sleeve 32 and engages in a recess 46 in the plug-in sleeve 32.
- a protrusion 47 also protrudes from the casing 38 toward the plug-in sleeve 32, which protrudes with an against the mounting direction 31 facing ramp 48 is provided.
- An arm 49 projects from the plug-in sleeve 32 transversely to the mounting direction 31 and can be pivoted elastically and comes to rest on the ramp 48.
- the plug part 30 When the plug part 30 is disassembled, the plug 36 is attacked and the plug is pulled by the light source 14 against the direction of the arrow j1.
- the arm 49 slides over the ramp 48 onto the projection 47, the part of the plug-in sleeve 32 with the projection 33 being pivoted thereby, so that the projection 33 is lifted out of the bore 21 in the contact pin 20. If the wall 42 at the front end of the receptacle 32 comes to the system according to the path s, the plug part 30 can be removed from the light source 14 with little effort with further movement against the mounting direction 31.
- a metallic ground contact element 50 which is connected to ground via a line 51, is arranged on the section 38 of the casing 36 surrounding the plug sleeve 32.
- the mass contact element 50 is best 1 - 'of a sleeve-like section 52 which is held on the section 38 and two of these to Light source 14 in the mounting direction 31 of the plug part 30, resilient contact arms 54.
- the sleeve-like section 52 is pushed against the arrow direction 31 onto the section 38 and, like this, is rectangular in cross section to the mounting direction 31.
- the sleeve-like section 52 has a slot 56 so that it can be elastically expanded transversely to the mounting direction 31.
- a protrusion 60 which is beveled toward the light source 14, projects outward from two mutually opposite outer sides of the section 38 of the envelope 36.
- a contact tab 62 to which the line 51 is connected also projects from the light source 14 from the sleeve-like section 52. The ends of the sleeve-like section 52 pointing away from the light source 14 are bent outwards in order to allow an easy pushing onto the section 38 of the casing 36.
- the contact arms 54 are bent toward one another in their region projecting beyond the section 38 of the casing 36 and their ends are bent in a U-shape, the apex of the U-shape of the two contact arms 54 facing each other.
- the contact arms 54 are provided with a bead 55 in their resilient area in order to increase their bending stiffness.
- the distance between the ends of the contact arms 54 is slightly less than the diameter of the cylindrical base section 22 of the light source 14.
- each contact element 50 has a protrusion 60 passing through an opening 58 in the sleeve-like section 52, as a result of which the contact element 50 is fastened in a latch-like manner on the section 38.
- the contact arms 54 of the ground contact element 50 are bent apart when their ends meet the insulating section of the base of the light source 14.
- the ends of the contact arms 54 rest radially against the cylindrical base section 22 of the light source 14 under pre-tension, so that the plug-side part 30 simultaneously establishes the plus-side connection and the ground connection of the light source 14.
- the contact arms 54 of the ground contact element 50 can also be designed such that they come to rest on the base plate 18 of the light source 14.
- only one contact arm 54 can be provided, or more than two contact arms 54.
- the light source 14 can also have a contact element other than the contact pin 20, for example a plug-in sleeve, in which case the plug part 30 is used to interact with the contact element trained plug element
- the electrical contacting of a light source described above is not limited to use with an HI incandescent lamp, but can generally be used with light sources in which a connection contact is provided only for the plus-side connection and the ground connection is made via the base of the light source.
