Definitions

  • the invention relates to a lamp holder in the preamble of Claim 1 mentioned Art.
  • Such sockets are widely used for mounting and electrical contacting of lamps in a wide variety Lighting equipment. These usually include lighting devices in addition to lamp and socket also reflective and / or refractive optics of different complexity, for the respective Application are optimized. It is particularly important that the actual filament to the surrounding optics in a well-defined spatial relationship. A manual tailored to the individual case Adjustment of the filament and / or optics comes predominantly Most of the cases are out of the question. Rather, most manufacturers manufacture the lamps such that the filament is relative to an abutment surface or line has a precisely specified orientation on the lamp base. The Versions that are usually fixed relative to the lighting optics point therefore usually a corresponding reference surface, the one automatic alignment of the lamp z. B. by resilient loading of the Lamp base against the reference surface.
  • Versions which include a ceramic one Have lower housing part, in which recesses for the introduction of Contact pins are provided. Usually one of these points Recesses a prism-shaped taper on the opposite spring loaded contact plate is arranged so that the inserted Contact pin pressed through the contact plate into the prismatic groove and so that it is fixed to the lower part of the housing. More contact pins are on set similar manner, but here often manufacturing tolerances can be taken into account by the oblong shape of the recesses should.
  • the Contact consists of two interlocking molded parts, the one hand the joint jointly a receptacle for a contact pin form and which on the other hand of the joint have a spiral spring, which the expansion of the recording by inserting the contact pin resilient force opposed.
  • the entire contact unit is on the same level vertically movable to the target position of the contact pins so that the contacts in their position the respective position of the contact pins can adjust. This does not result in any damage to the lamp base as such Force exerted, which is why a clear alignment on the contact surface of the Lamp base and the corresponding reference surface of the Lamp holder is made possible.
  • the disadvantage here is the complex and expensive manufacture of the contacts as well as the lack of possibility of a Adaptation to slanted contact pins.
  • the contacts must go out be made of electrically conductive material, what their embedding in one ceramic socket base necessary, but due to the movable bracket must be made in two parts, which additional Cost means.
  • Another known solution has individual contacts for each contact pin Contacts that have a cylindrical shape corresponding to the contact pins. They are formed from a base plate with several tongues, the Tongues bent at right angles to the bottom plate and at their upper end be connected with a spring washer. In this chalice-like structure, which in a ceramic housing base is inserted, a contact pin used.
  • this solution has considerable disadvantages: the The opening diameter of the contact cups is only minimal elastically expandable, whereby the sometimes considerable tolerances in the Diameters of the contact pins can only be insufficiently compensated. As a result, it is particularly common at high temperatures faulty contact.
  • the object of the present invention is therefore to provide a version of to provide the aforementioned type, on the one hand, a reliable Contacting of the contact pins guaranteed and on the other hand alignment the lamp only on its intended contact surface on Lamp base allows, the cheap manufacture of special Meaning is.
  • a subordinate task, in particular the aspect of cheap manufacturing concerns, the modular structure of the contacts, the use in frames of different shapes and / or materials enables, which in particular also greater freedom in the design of the frames allowed.
  • a single, spring-loaded contact provided in an electrically insulating, preferably ceramic contact cage is arranged.
  • This contact cage is essentially free relative to all other units of the version movable, what translations along all spatial axes and this partial rotations around includes.
  • the contact pins are contacted to the contact pins spring-loaded contact plates in any case parallel to the contact pin what optimal contacting guaranteed.
  • one is preferred Contact pin in a prism-shaped recess of the Contact cage introduced, ensuring the secure mounting of the contact cage and the contact on the contact pin is still improved.
  • the contact plates are preferably pressed against the contact pin by a spiral spring. This creates a particularly long spring travel, which means even at higher ones Temperatures that secure contacting remains guaranteed.
  • Another advantage of the version according to the invention is that Possibility of a particularly simple construction of the lower housing part. Since the Isolation of the contacts against each other and against the housing already largely guaranteed by the electrically insulating contact cages is only a sufficiently large space in the lower part of the housing All contact cages can be accommodated. A special spatial and / or electrical separation is not necessary. From this results in particular the possibility of at least the lower housing part partially made of metallic materials, which has advantages in the Can have heat dissipation as well as in the design.
  • Version 1 The special embodiment of the shown in the drawings Version 1 according to the invention is composed of a metallic Upper housing part 10 and a ceramic lower housing part 20 together.
  • the lower housing part 20 has a receiving space 21 for the Contact cages 30 on.
  • the upper housing part 10, which is preferably made of nickel-plated steel sheet is characterized in particular by the Presence of a reference surface 11, on which in Final assembly condition of the contact surface 44 of the lamp base 43 one Assembly provided lamp 40, which also a glass ball 41, a Filament 42 and contact pins 45 protruding from the lamp base has to come to rest.
  • a spring element 14 is provided, which is shown in the Embodiment is designed as a leaf spring.
  • the Federelernent 14 exists from the actual spring body 141, to which an upper 142 and a Attach lower 141 fastening edge. With these mounting edges 142, 143 become the upper and lower edges of the reference surface 11 opposite side of the upper housing part 10 at least in regions attacked. In this way, the spring element 14 is preloaded generated.
  • the contact surface 44 of the Lamp base 43 against the reference surface 11 of the upper housing part 10 pressed, causing an automatic alignment of the filament 42 relative to achieve the optics of the lighting device.
  • the lower housing part 20 essentially fulfills two of the invention Tasks, namely the mounting of the upper housing part 10 and the Recording the contact cages 30. In the one shown in the drawings Embodiment you also comes to the task of fixing the entire version 1 in the lighting device. For this are in Lower housing part 20 guides 24 are provided for fasteners.
  • the contact cages 30 come in the recess provided for this Lower housing part 20 to lie. According to the invention, this is too large design that sufficient mobility of the contact cages 30th is guaranteed so that a complete adjustment of the contact cages 30 to the contact pins 45 is possible.
  • the contact cage 30 is made of an electrically insulating material, preferably ceramic. In it is a recess 31 for Inclusion of a contact pin provided. This is particularly cheap realize as a breakthrough.
  • the recess 31 can be divided into two sections divide. A first section, preferably one-sided prism-shaped (32) is designed to actually accommodate the Contact pin 45. It is replaced by a contact plate 33 from a second Section of the recess 31 separated.
  • the second section of the Recess 31 offers space for the connected to the contact plate 33, preferably welded (36), electrical supply line 38 and for one Spiral spring 35, which is under tension on the one hand on the wall of the Recess 31, on the other hand supported on the contact plate 33.
  • the Contact plate 33 is thus against contact pin 45 not yet inserted pressed a projection 34 serving as a guide and in its position held.
  • the first section of the recess 31 is to be dimensioned such that a Inserting the contact pin 45 only by moving the Contact plate 33 against the force of the spiral spring 35 is possible.
  • the prism-like shape of the recess 31 can be the entire Align the contact cage 30 relative to the contact pin 45 so that the Contact plate 33 always parallel, d. H. with maximum touch of his Contact surface 331, bears on contact pin 45.
  • the spiral spring 35 given long travel ensures that even at higher temperatures sufficient contact pressure is always maintained.
  • the upper edges of the first Chamfer part of the recess 31 are preferably the upper edges of the first Chamfer part of the recess 31.
  • the upper edge 332 of preferably made of temperature-resistant Contact material manufactured contact plate 32 angled outwards become. This also has the advantage that the spiral spring 35 against Jumping out is secured. It is favorable if one in the contact cage special recess 37 for carrying out the electrical supply is provided.
  • the electrical Isolation of contact plate 33 and spiral spring 35 for metallic Upper part 10 of the housing for example, by the one shown in FIG. 4 electrically insulating intermediate layer 25 realized.
  • the openings 251 in the intermediate layer 25 are significantly larger than the diameter of the contact pins 45 to be inserted. Otherwise the contact pins 45, e.g. B. with a significant inclination, a Fixing on a part rigidly connected to the lower housing part 20 learn what the basic idea of the invention, namely the exclusive Alignment of the lamp would conflict with the contact and reference surface.
  • the exemplary embodiment shown shows further, advantageous, but not Details relevant to the invention, which are briefly discussed below shall be.
  • the upper housing part 10 is provided with fastening feet 13, which when mounting the socket 1 in corresponding slots 22 of the Lower housing part 20 are introduced.
  • the outer edges of the contact cages 30 are chamfered, thereby creating a mutual wedging is prevented, which the individual alignment each contact cage 30 according to the particular location of it associated pin 45 would hinder.
  • Housing upper and lower part (10, 20) do not necessarily have to be in two parts.
  • Housing upper and lower part (10, 20) do not necessarily have to be in two parts.
  • a cover and base plate for the contact cages Ensuring that the live parts are completely insulated is one one-piece design of the housing made of metallic material is conceivable. This could have advantages, particularly when it comes to heat dissipation.
  • the ceramic base 20 could be of the Upper part 10 are at least partially included.
  • To align the Lamp base 43 with its contact surface 44 on the reference surface 11 of the Upper housing part 10 could use other spring elements 14 than leaf springs become.
  • the reference surface 11 is also conceivable for the reference surface 11 to be resilient Design structure, so that the lamp base 43 resilient on both sides is burdened and fixed.
  • the contact sheet / coil spring combination could also be used 33/35 of the contact cages 30 by a leaf spring designed contact plate 33 are replaced.
  • the state of the Technology manifold variations are conceivable, the shape and size of the pins 45 in particular being almost arbitrary can vary.
  • the version 1 shown in the drawings represents only an exemplary embodiment without a restrictive character.
