Definitions

  • the invention relates to a substructure for an electric lamp, with a cylindrical housing and a base.
  • the present invention is therefore an object of the invention to provide a substructure for an electric lamp, which can be realized with little effort and cost. This object is achieved by a substructure, which has the features of claim 1.
  • An inventive substructure for an electric lamp comprises a cylindrical housing and a base.
  • the housing and a first portion of the base are integrally formed of a first plastic.
  • a relatively inexpensive production can be made possible.
  • the subsequent connection of the housing with the base omitted.
  • a base crimping is no longer required, which also strength problems, as they can occur in the prior art, no longer exist.
  • thinner wall thicknesses of the housing and the base can be made possible in the region of the earlier base crimp, which results in material savings.
  • an insert is connected to the housing and the base and at least partially formed of a second plastic.
  • a second subregion of the base in particular a region of an external thread, is formed at least partially from the second plastic.
  • different plastics can be formed for different subregions of the substructure.
  • explicit functionalities of the overall component can be precisely formed.
  • the second portion of the base is preferably formed integrally with the insert.
  • the insert part comprises a part of the base.
  • the base itself has at least two partial areas, which are formed from different plastic materials. Functional requirements of the socket can be formed individually and generated locally defined.
  • the insert part is completely formed from the second plastic material. It can be designed as an injection molded part.
  • the housing and the base can be made as an injection molded part.
  • the insert is preferably integrally formed with the housing and the So- ekel.
  • the insert part is provided as a finished molded part and is partially encapsulated for further production and production of the substructure. This encapsulation then forms the housing and the base.
  • the entire substructure, comprising the housing, the base and the insert, is then integrally formed from two plastics.
  • the components formed from the second plastic are preferably galvanisable. Defined areas of the substructure can then be metallized. Preferably, the first plastic is not galvanisable. As a result, areas of the substructure not intended for metallization can be prevented from being metallized.
  • a conductor track is applied to a web of the insert part, in particular galvanized.
  • an environmental relief in the production can be made possible.
  • a conductor track is preferably guided to a safety zone formed at the lower region of the insert part, and preferably a safety fuse divides the conductor track.
  • the discrete wire fuse used in the prior art is preferably replaced by a back-up zone applied galvanically to the housing wall, and moreover, preferably the side wire required in the prior art by an electrodeposited conductor track.
  • the second plastic is preferably thermoplastic urethane, in particular Durethan BKH 130.
  • the first plastic is preferably PBT, in particular Pocan B4235L.
  • At least one guide for a printed conductor is preferably formed on an inner side of the housing and / or the base.
  • the web of the insert part can then preferably be inserted into the guide of the housing and / or the base or be formed integrally therewith.
  • the conductor can be held and fixed in exact position.
  • the guide is preferably formed integrally on the upper part and / or the lower part.
  • a conductor track is advantageously formed on the inside of the housing and / or the base.
  • a fixation for a fuse is preferably formed on the inside of the housing.
  • the fuse can also be kept stable position.
  • the fixation may be integrally formed with the housing.
  • this fixation and the guide for a conductor made of plastic is formed.
  • an external thread is formed on the outside of the base, whereby the base can be screwed into a lamp holder.
  • at least the second portion of the base which comprises a portion of the external thread metallized.
  • the substructure is designed for a discharge lamp and preferably an electronic ballast is arranged in the housing.
  • Fig. 1 is a side view of a substructure according to the invention
  • FIG. 2 shows a perspective view of the substructure according to FIG. 1 from below;
  • Fig. 3 is a further perspective view of the housing and the base of the substructure according to Figures 1 and 2.
  • FIG. 4 is a perspective view of a separated insert part of the substructure according to the invention.
  • Fig. 5 is a further perspective view of the substructure.
  • Fig. 1 is a side view of a base 1 for a discharge lamp (not shown) is shown.
  • the substructure 1 comprises a housing 2 and a base 3, which are integrally formed.
  • a first portion 3a of the base 3 and the housing 2 are formed of a first plastic, which in the exemplary embodiment is Pocan B4235L.
  • an electronic ballast (not shown) of the discharge lamp is arranged in the housing 2.
  • a discharge vessel, not shown, of the discharge lamp is arranged in the region I and connected to the substructure 1.
  • the base 2 has a second portion 3b, which is limited in its dimensions by the horizontal dashed lines and which is formed of a second plastic. In the exemplary embodiment, this is Durethan BKV 130. On the outside of the base 3, an outside draft 31 is formed. In the second portion 3b, and thus in the region in which the second plastic is formed, the base 3 is metallized.
  • the base 3 At its end portion 32 remote from the housing 2, the base 3 is cone-shaped. Centered and centered on this end region 32 is a through-connection 33a. This is in the perspective view of below to recognize in FIG. 2. A further through-connection 33b (FIG. 2) is formed in the galvanized region of the external thread 31.
  • FIG. 1 Another perspective view of a subelement of the substructure 1 is shown in FIG.
  • the formed as a pre-molded component has on an inner side of the housing 2, two guides 21 and 22 which are also formed integrally with the housing 2 and thus also with the substructure 1.
  • These two guides 21 and 22 extend parallel to one another and extend in the vertical direction substantially over the entire height of the housing 2.
  • a conductor track can be anchored and arranged in a positionally stable manner. It can be provided that this conductor track is formed on the inside of the housing 2. In particular, in the area between these guides 21 and 22, this conductor may be appropriate.
  • a fixing is formed on an inner side of the transition region, which comprises the two webs 23 and 24.
  • a fuse 44 (FIG. 4) can be held.
  • 3 guides 34 and 35 corresponding to the guides 21 and 22 are formed on an inner side of the base. This also allows a conductor track to be kept positionally stable.
  • the conductor track is arranged on the inside of the base 3.
  • FIG. 4 an insert part 4 is shown in a perspective view, which is shown as a separate element.
  • the insert 4 is formed as a one-piece injection molded part and formed from the second plastic material. Starting from the illustration shown in FIG. 4, in which the insert part 4 is designed as a finished molded part, it can then be provided to overmold it with a preform part, as shown in FIG. 3. This is preferably carried out in 2K injection molding by injecting the insert 4 into the component according to FIG. 3.
  • the housing 2, the base 3 and the insert part 4 are then integrally formed.
  • the insert 4 is preferably formed of Durethan BKV130.
  • the insert 4 comprises a cone-shaped base 41, which corresponds to the second portion 3b of the base 3 and forms this.
  • ribs 42, 43 and 46 formed on both sides are then inserted into the guides 21, 22, 34, 35 and 25 as well as 25, 26 and 36 and 37.
  • a conductor can then be applied, in particular galvanized.
  • the webs 42, 43 and 46 are formed from the metallizable second plastic.
  • a fuse 44 is mounted between the webs 42 and 43. This is after the encapsulation of the insert part 4 through the housing 2 and the base 3 in the fixation, comprising the webs 23 and 24, used.
  • the webs 42 and 43 and the conductor tracks formed thereon are connected to a fuse zone 45. At the upper free ends of the webs 42 and 46 contacts for the electroplating are provided.
