Definitions

  • the invention relates to a luminaire in whose a plastic housing handle a button cell battery equipped with a circumferential and central surface pole can be brought into the switch contact position against the force of an elastic element lying against it, by a partial area of the central surface pole of the button cell battery coming into contact with one Section of a contact lamella, the button cell battery lying in a receiving chamber of the housing and or the peripheral pole of the button cell battery in constant contact (permanent contact) to a contact spring extending tangentially to the button cell battery, the width of which corresponds at least to the stroke of the button cell battery.
  • Such a luminaire is known from DE-U-1 850 084, which has a strip-shaped contact lamella with a centrally raised, cut-out switching finger contact. Furthermore, a rubber ring spring is provided which rests on one side on the contact lamella and on the other side is in contact with the central surface pole of a button cell battery.
  • the functional safety of this lamp is not always guaranteed, since the button cell battery must be applied in such a way that the rubber ring spring is squeezed together as evenly as possible. This requires a forceful, very targeted, central pressure actuation, since only the center of the center surface pole can come into contact with the centrally bent switching finger contact of the contact plate. Pressurization of the button cell battery on the edge, on the other hand, usually does not lead to contact since the area near the edge of the central surface pole is covered by the rubber ring spring. Furthermore, this known lamp has a relatively large thickness due to the rubber ring spring.
  • DE-A-3 126 774 shows a lamp which can be connected with a key and which has a conical spiral spring which forms a permanent guide element between the central surface pole of a button cell battery and a contact disk. Furthermore, a contact ring is provided which interacts with the central surface pole of the button cell battery. The contact ring is held only at two diametrically opposite points and otherwise extends freely inside the housing of the lamp. Due to the largely lack of support, the ring can deform due to excessive contact with the button cell battery, so that the functional safety of the lamp is questioned. Furthermore, the position of the conical spiral spring is not adequately secured, so that it slips and can thus jeopardize the functional reliability.
  • the invention has for its object to provide a generic lamp that is extremely flat and reliable.
  • the contact lamella has a circular ring section resting on the housing base and that the elastic element is designed as a compression spring running concentrically to the ring section, of which at least the bottom end turn lies in a recess in the housing base, the diameter of the The depression is smaller than a ring section opening of the ring section surrounding the depression, onto which the central surface pole of the button cell battery is placed in the switching contact position.
  • a luminaire which is extremely flat and can be assigned to a key with a high level of functional reliability and simple construction is created in a most favorable manner.
  • the flat center surface pole which protrudes slightly from the jacket of the button cell battery and always has a safe switching contact, is placed on the circular ring section underneath which is supported by the housing base. Since the tilting position, which is possible in many directions, means that changing places close to the edge always work together, there is not so easily a risk of scale formation. Rather, there is a self-cleaning effect at the contact points.
  • the contact spring extends at an acute angle to the receiving space aligned parallel to the key shaft.
  • the contact lamella contacts the incandescent lamp base with a contact tab angled beyond the contact spring out of the plane of the ring section and the contact tab formed in this way additionally by an elastic one , housing-supported body is system-loaded.
  • the elastic body is cylindrical, is in a shaft and is overlaid by a hold-down of the housing cover.
  • the correspondingly resilient system can also be used for the contact spring, in that the contact spring, which is in constant contact with the peripheral surface pole, rests with its free end resiliently on the bulb base and is additionally stressed there by an elastic or resilient body (Fig. 20).
  • the contact spring which is in constant contact with the peripheral surface pole, rests with its free end resiliently on the bulb base and is additionally stressed there by an elastic or resilient body (Fig. 20).
  • the ring section of the contact lamella has a plurality of claws on the edge side, arranged essentially in the same angular distribution, which claw like barbs in the cylindrical wall of the receiving chamber for the button cell battery.
  • the clawing takes place in guide shafts running in the direction of insertion.
  • the area of the key 1 is designed as a lamp L.
  • the housing 2 which forms the handle of the key accommodates a button cell battery 3 centrally.
  • the flat, disc-shaped housing shown in FIG. 1 is made of insulation material, for. B. plastic, manufactured and closed by means of an annular cover 4 by means of an edge-side clip connection.
  • a central, cylindrical receiving chamber 5 for the button cell battery 3 extends from the wide surface of the housing 2 facing the cover 4. The latter is axially displaceable against spring loading.
  • the corresponding compression spring 6 is supported on the bottom 7 of the receiving chamber 5. At least its bottom end turn 6 'is in one of the recess 8 of the bottom 7. It is a conical spring, the other end turn 6 "loads the lower flat side of the button cell battery 3 in the middle in the direction of the basic position (FIG. 5).
  • the spring-loaded basic position is defined by an annular shoulder 11 of a cone-like actuation button 12 overlapping the button cell battery 3.
  • the latter protrudes with its smaller cross-section, cylindrical section in a shape-corresponding, continuous opening 13 of the lid 4.
  • the annular shoulder 11 occurs against the underside inner edge of the opening 13.
  • the hat space receives the upper, cylindrical section of the button cell battery, which widens in the area of the lower edge of the hat to the circumference of the same , in order to finally end in the shape of a truncated cone in the direction of the bottom 7.
  • the shoulder between the cylindrical and frustoconical section of the button cell battery is designated by 14.
  • the peripheral transition has a transverse rounding 15.
  • the jacket wall of this section forms the peripheral pole UP.
  • the peripheral pole UP is in constant contact with a contact spring 16 which extends essentially tangentially to the button cell battery 3. The width thereof corresponds at least to the stroke x of the button cell battery 3.
  • the contact spring is held in a shaft 17 (FIGS. 3 and 13) of the housing 2.
  • the shaft 17 ends at a distance y (FIG. 6) in front of the receiving chamber set surface 7 'of the base 7, which distance is greater than the thickness of the contact lamella 9.
  • a receiving space 18 for the incandescent lamp 19 of the lamp L adjoins the cylindrical receiving chamber 5 in the direction of the edge of the housing.
  • the receiving space 18 and the receiving chamber 5 are open to one another on a partial section.
  • the contact spring 16 extends in the corresponding break-through zone and is only tied at its two narrow ends 16 'and 16 ", so that when the button cell battery is moved downward it finds its spring escape space there, namely the shaft 17 takes an inclined course in the direction of displacement. This has the advantage that with increasing push-in movement there is an even firmer contact between the peripheral pole and the corresponding spring surface.
  • the incandescent lamp 19 forms an annular collar 20 in front of the glass bulb.
  • the latter is located in a transverse shaft 21 of the housing 2.
  • the light bulb 19 is oriented in the direction of the key shaft. It extends in the plane of the key edge.
  • the contact spring extends at an acute angle (angle alpha) to the receiving space aligned parallel to the key shaft 1 '(FIGS. 3 and 13).
  • the contact lamella 9 projects with a contact lug 22 angled beyond its contact spring 16 out of its flat plane into the area of the bulb base 23.
  • the lug initially takes an almost tangential course to the ring section 9 'and is then angled once or twice transversely to the direction of extension.
  • the tangentially directed contact spring 16 occurs with one, d. H.
  • the end on the incandescent lamp side which cuts the receiving space for the incandescent lamp on the circumference, against the thread-bearing jacket of the incandescent lamp 19, specifically against the annular collar 20 produced by outward folding, which continues at the rear into a thread-free, cylindrical section, so that the contact via the narrow end 16 "is always safely maintained.
  • the actuation button ends flush with the outer broad surface of the cover 4, but is concavely hollowed out towards the center.
  • the cover 4 also closes the upwardly open receiving space 18 for the incandescent lamp 19.
  • the depth of the space essentially corresponds to that of the incandescent lamp diameter.
  • the light does not need to be operated strictly centrally; due to the ring section 9 ', regardless of the tilting position of the button cell battery, at least a partial area thereof always comes into contact with the ring section.
  • the lights that can be equipped with a key shaft according to the second and third exemplary embodiments are basically of the same construction. As far as is necessary for understanding, the reference numbers are transferred analogously without a textual repetition of the matching features.
  • the contact lug 22 of the contact lamella 9, which rests resiliently on the bulb base 23, is in the direction of the bulb 19 to reinforce the resilient system by means of an elastic body 24, for example made of foam charged.
  • the cylindrical body in its basic form rests in a shaft 25 of the housing 2 located behind the lamp base.
  • the shaft is partly formed by the receiving space 18.
  • a congruent hold-down device 26 extends from the housing cover 4. It is a molded cylindrical pin that extends to the top of the elastic body. The pin can be seen in FIG. 15.
  • the contact lamella 9 leads to the bulb socket 23
  • the contact lamella 9 is guided to the ring collar 20 of the bulb 19 and is in constant contact with the Circumferential surface pole UP standing contact spring 16 at its free end in contact with the bulb socket 23.
  • the contact spring takes 16 a multiple angled course, the directly contacting end being angled in a V-shape and the V-tip resting on the bulb base 23.
  • this free end is also loaded by an elastic or resilient body 24 '.
  • This body consists of a plate, which is inserted diagonally into the shaft area there and lies against the free V-leg, which is stressful.
  • the measure is taken that the contact lamella 9 extends in the direction of the key shaft (FIG. 16). Your lateral support is formed by ribs 27 which extend laterally of the contact lamella 9.
  • the basic shape of the lamp body also differs insofar as it now has an essentially triangular shape with slightly convex long sides.
  • the clip assignment of the cover is also solved differently in that it forms a hammer head 28 with lateral, bevelled tabs which engage behind the corresponding undercuts of the housing 2.
  • the end of the cover 4 opposite the hammer head 28, on the other hand, is simply clipped into the receiving chamber 5 for the button cell battery 3.
  • the latter has corresponding locking recesses 30 into which the locking projections 31 of the cover 4 snap.
  • a special feature of the exemplary embodiment according to FIGS. 9 to 15 is that the ring section 9 ′ of the contact lamella 9 has a plurality of claws 9 ′′ arranged essentially in the same angular distribution on the edge, which are located in the cylindrical wall of the receiving chamber 5 for the button cell battery 3
  • the clawing takes place on the bottom of guide shafts 32 which run in the direction of insertion of the ring section 9 'and which are adapted to the contour of the claws 9 "and ensure an optimal rotation lock of the circular ring section 9'.
  • the insertion end of the key shaft 1 ' is forked. It enters a shaft of the housing corresponding to the fork shape and is fixed by a locking bolt 33 which is spring-loaded in the direction of the basic locking position.
