Definitions

  • the invention relates to an electric lamp which consists of a lamp bulb squeezed on one side with current leads led out at the pinch, a holding element made of metal which fixes the lamp bulb, a cup-shaped base sleeve made of plastic and at least two base contacts.
  • the base plate of the cup-shaped base sleeve is provided with through-holes for the passage of the current leads.
  • Such lamps are known for example from DE-GM 82 01 526, which, among other things, are intended to hermetically seal a motor vehicle headlight at its apex opening.
  • at least one groove with a sealing ring is provided on the circumference of a base sleeve made of plastic, the sealing ring resting on the reflector neck of the headlight.
  • the power supply lines of this lamp are passed through openings in the base of the base sleeve and through openings in the base contacts, which are aligned with the former, and then welded to the base contacts in such a way that the base contact openings are also hermetically sealed. Since such a welding process is quite complex and complex, attempts have been made to find a construction which allows the lamp to be sealed in a simple manner from its base and also the connection points between power supply lines and protect base contacts from weather and mechanical influences.
  • connection part made of insulating material is attached to the end of the base sleeve facing away from the lamp bulb, which has a wall part through which the base contacts are passed, and which forms a cavity with the base plate of the base sleeve in which the connection points between the power supply lines and base contacts are located.
  • the base contacts With their ends protruding into the cavity, the base contacts are mounted on a further wall part, whereby a fixation is achieved.
  • a continuous opening in the base plate of the base sleeve is formed solely by the holes for the power supply lines. However, their diameter is only slightly larger than that of the power leads themselves, so that the holes can be easily closed afterwards. In one case, it is closed by base sleeve material, which previously surrounds the holes in the form of a collar and is melted. In a further advantageous embodiment, it is also possible to seal these openings with resins made of plastic (e.g. silicone), which is easier to handle in terms of production technology.
  • plastic e.g. silicone
  • the base sleeve consists of a high-temperature-resistant plastic material that withstands the heat radiated by the lamp bulb.
  • the connector can be made of a less expensive plastic.
  • the connection of the two parts to each other is carried out by ultrasonic heating, with one of the parts Nipples or projections are formed which, when melted down, undercut the other part.
  • the lamps for motor vehicle headlights shown in the figures consist of a lamp bulb 1, 21 pinched on one side with one (FIG. 4) or two (FIG. 1) luminous elements 2, 22.
  • the power supply lines 3, 23 are led out of the lamp pinch.
  • the lamp is an incandescent lamp, to which a halogen addition has been added to the inert gas.
  • the lamp bulb 1, 21 is surrounded on its pinch by a sleeve 4, 24 made of metal, which is part of a holding element 5, 25 and is connected to the base sleeve 7, 27 made of plastic via molded webs 6, 26.
  • the lower ends of the webs 6, 26 are provided with a bead and this is provided with openings, so that when connecting the two parts 6, 7; 26, 27 can penetrate base sleeve material by means of high-frequency heating. This ensures a firm and secure connection.
  • the base sleeve 7, 27 itself consists of a cup-shaped plastic part, the open end of which faces the lamp bulb 1, 21.
  • this plastic is very heat-resistant, since temperatures of up to 240 C arise from the burning lamp.
  • a possible plastic is, for example, a polyphenylene sulfide reinforced with glass fibers and mineral fillers.
  • the base plate of the base sleeve 7, 27 is provided with bores 8 (not shown in FIG. 4) for the passage of the current leads 3, 23. Their diameter is only slightly larger than that of the power supply lines 3, 23 themselves. Molded funnels 9 facilitate threading. To seal the base sleeve 7 to the lamp bulb 1 in the exemplary embodiment according to FIG. 1, the bores 8 are closed by introducing resins on the back of the base plate.
  • the knife-shaped base contacts 10 of the lamp according to FIG. 1 are mounted on the back of the base plate in slot-shaped blind holes 11, into which the contacts 10 are fitted with a play-free seat.
  • the current leads 3 protruding through the base plate are welded to the base contacts 10 on this side, two of the four current leads 3 being connected from only one end of the two luminous elements 2 (ground contact) to only one base contact 10.
  • connection part 12 which has bushings for the base contacts 10, is placed on this lamp base sleeve unit from below. It is constructed in such a way that the connection points between power supply lines 3 and base contacts 10 are arranged in a closed cavity 13.
  • the resin provided for closing the bores 8 fills this entire cavity 13 and thus seals all the gaps, that is to say also the bushings for the base contacts 10 in the connecting part 12.
  • Base sleeve 7 and connector 12 are riveted together.
  • 7 nipples 14 are formed on the back of the base sleeve, which protrude through openings in the connecting part 12 and are deformed by means of ultrasound.
  • the connecting part 12 itself can consist of a plastic material which is not as heat-resistant as that of the base sleeve 7, since no such high temperatures arise on this part. This has the advantage that the lamps - apart from the technically advantageous two-part design of the base - can be manufactured inexpensively.
  • the connecting part 32 of the lamp according to FIG. 4 is pot-shaped.
  • the base contacts 30 are passed through a side wall part of the connection part 32.
  • the ends of the base contacts 30 projecting into the cavity 33 are supported by a projection 28 on the wall part, which is opposite the one provided with the bushings for the base contacts 30, this projection 28 cooperating with a groove in the base contact 30.
  • the connecting part 32 is fastened to the base sleeve 27 before the power leads 23 are connected to the base contacts 30. This is done by projections formed on the connection part 32, the material of which flows after melting into a circumferential groove 29 arranged in the base sleeve.
  • the connecting part 32 has an opening through which the cavity 33 is accessible for the operation of connecting the power supply 23 and the base contact 30. After the welding process, the opening is closed by a cover 40.
  • This cover 40 advantageously has lugs 41 on its inside, which cooperate with a further groove in the base contacts 30.
  • the base contacts 30 are thus also secured in their axial direction and cannot be pulled out when a plug is removed.
  • the base is sealed by means of collars 42 formed on the bore for the passage of the current leads, which are melted after the passage of the current leads 23 and fit tightly against them. Sealing can also be carried out by pouring resin with the cavity (e.g. with silicone rubber).
  • a sleeve 15, 45 surrounding the base contacts 10, 30 is formed on the connecting part 12, 32 and is provided for receiving in a plug.
  • the base contacts 10, 30 are thus largely against moisture and thus before Corrosion protected and good contact is guaranteed.
  • the nose 16, 46 is provided on the sleeve 15, 45 against unintentional loosening of the plug.
