Definitions

  • the invention relates to an incandescent lamp socket, consisting of a one-piece socket body designed as a plastic injection-molded part with preferably screwless conductor connection and lamp contact springs embedded therein, with an internal thread for screw mounting the lamp and an external thread for mounting e.g. a screw ring are formed, wherein the conductor insertion openings opening into the ceiling of the lampholder body provided with screw fastening openings are flanked by web strips, the free end face ends of which end in a common plane parallel to the ceiling and, if necessary, in the ceiling area on opposite sides of the lampholder for engaging latching hooks the socket body of detachable socket dome are arranged.
  • Such a bulb holder of dimension E 27 is known from the prior use by the applicant.
  • Such a version preferably made of poly-butylene glycol terephthalate (PBTB)
  • PBTB poly-butylene glycol terephthalate
  • the known version essentially has a cylindrical casing which is provided with an external thread over its own entire length and the length of the socket body. At the upper end, that is to say associated with the frame ceiling, there are diametrically opposite arrangement in the frame coat two incisions, each of which is assigned a locking lug.
  • a lampholder spanning the incandescent lamp socket can engage in these incisions, with its latching tongues protruding freely in the axial direction.
  • the ceiling of the socket extends approximately flush with the upper edge of the bulb socket.
  • two spaced screw fastening openings are made and offset to this in a paired arrangement of conductor insertion openings.
  • a web strip arrangement is provided on the outside of the ceiling, which on the one hand surrounds or flanks the screw fastening openings and on the other hand the conductor insertion openings.
  • the free ends of these webs lie in a plane parallel to the ceiling and thus form a support for a screw-on surface.
  • the known version can be attached to such a surface directly with the aid of two screws penetrating the screw fastening openings from the inside of the version, for example inside a bowl-shaped lamp housing made of wood, for example.
  • the conductors can be fed into the conductor insertion openings in a direction approximately parallel to the socket ceiling, into which they then plunge parallel to the socket. It is also possible to provide an opening in alignment with the area of the conductor insertion openings on the light side and to conduct the conductors there in a straight line.
  • Another possibility of fastening is given by the use of the socket, which can be attached to a lamp bracket or a lamp tube, for example, and a zen trale opening for carrying out the connecting conductor. With this dome, which is then fastened on the light side, the socket can be releasably plug-in locked.
  • the known version despite its undeniable advantages, in particular with regard to its multiple attachment options, is relatively expensive, since it has an externally threaded jacket that is pulled through from the lamp screw-in side to the ceiling, although a further jacket is arranged inside the jacket.
  • the invention is based on the object, starting from the known and outlined in the preamble of claim 1 bulb holder this in a skillful way while saving material in such a way that it has other or additional fastening options and enables a more economical routing of the connecting conductors.
  • the external thread extends only over a lamp-side section of the lampholder body, which in a section below the lampholder body cover has an outer diameter that is tapered compared to the externally threaded section, that the lampholder cover is designed as a thin-walled flange, which at least two distributed over the circumference, open towards the flange and the ladder insertion openings arranged adjacent notches, and that the web strips form a channel open to the notches.
  • the invention is limited to reducing it only by providing a shorter external thread section on the lampholder in the vicinity of the lamp screw-in opening. This is based on the knowledge that the new version should primarily be suitable as an installation version in existing luminaire bodies, reflectors or the like, and that consequently an external thread section extending to the ceiling of the version is dispensable. This measure alone can, for example, save a third of the material used for its casing, based on the previously known version.
  • the thin-walled flange provided in the ceiling area also referred to as the "collar" offers several advantages in its marked version, despite the low material consumption.
  • the notches provided in the vicinity of the conductor insertion openings of the incandescent lamp holder enable the conductors to be laid essentially one or more times in an S or Z shape from their entrance to the contact springs.
  • This multiply deflected conductor routing allows strain relief to be achieved in the simplest way, which, in addition, with the appropriate laying of the conductors inevitably also takes place without a strain relief that has to be operated in particular organs, such as clamps, clamps, screws or the like.
  • the flange-side notches have another advantage, however, because they are suitable for engaging under-grip tongues attached to a lamp plate for hajonet-like coupling of the socket to the lamp plate.
  • a support bracket such as the bottom of a lamp reflector, can also be considered as a "lamp plate”.
  • the flange then serves as an abutment for the grip tabs and its peripheral edge serves as a centering support.
  • the incandescent lamp holder designed in this way thus has an additional possibility of attaching the bayonet-type plug-in coupling and, using the same means, the possibility of a simple strain-relieved connecting conductor guide.
  • the notches each have at least one partial section, the gap width of which is smaller than the diameter of an insulated conductor.
  • the conductor can be squeezed into notches of this size with partial elastic deformation of its jacket, which results in a further increase in the strain relief.
  • the latching lugs for the socket dome are flanked by web strips which are arranged on the socket and on the notches circumferentially offset over a length corresponding to the length of the dome-side latching hooks.
  • the web strips flanking the latching hooks of the cathedral, leading and non-rotatably supporting the cathedral with respect to the socket accordingly have the further function of separating the conductors that are led from them towards the socket, so that one conductor on one and the other on the other socket side can be performed across the jacket to the contacts. Then it is also possible in a simple manner to attach the socket already fitted with the conductors to the dome, since its latching hooks can inevitably enter between the conductors which are held apart by the web strips, without damaging them.
  • the screw fastening openings in the socket cover are advantageously surrounded by sleeve-shaped collars, which leave a clamping gap for a connecting wire between their outside and adjacent web strips.
  • a particularly favorable form of the web strips is characterized in that they are divided into four, each V-shaped webs, the successive two legs of which run parallel to one another in the circumferential direction, such that two parallel legs of two V-webs each have a channel between them form, with each channel in the circumferential direction alternately a screw fastening opening and at least one conductor insertion opening is assigned.
  • the notches (for the conductor routing and the bayonet-type attachment to a socket support) are expediently arranged at the end of each channel having the conductor insertion opening, while at the end of the channels having the screw fastening openings, the latching lugs are arranged in the material thickness of the latching hooks on the base, corresponding to correspondingly deep notches.
  • the web strips end at a distance from the flange edge and approximately on a common circular line whose center lies in the longitudinal axis of the frame.
  • the edges of the web strips which point outward in the circumferential direction thus form an effective centering aid when inserting the mount on the ceiling into a cutout of a mount support, in particular a sheet having the means for the bayonet-type fastening.
  • the frame designated by 10 consists of a one-piece and one-piece plastic body 11 made in particular of PBTB.
  • the socket body 11 is in the direction of the longitudinal axis 12 essentially in four consecutive Zones divided.
  • an external thread section 13 is initially arranged, the axial length of which corresponds to approximately a quarter of the total length of the socket body.
  • a flat cylindrical section 14 which has the internal thread for the lamp base on the inside.
  • a diametrically opposed arrangement each of which has two mutually parallel web strips 15, which are otherwise essentially cylindrical, and which, at the end, have an annular collar-like flange 17 as the fourth socket section. This forms the ceiling 18 of the socket 10.
  • a locking lug 20 is injection molded on the shell side in close association with a notch 19 of the flange 17. This is used for the plug-in coupling with resiliently expandable latching hooks 21 of a socket dome D, with which the socket body 11 can be detachably plug-in.
  • the mutually facing inner surfaces of the webs 15 serve to secure the position of the dome-side latching hooks 21.
  • V-shaped web strips 22 are provided, which are perpendicular to the base surface.
  • the web strips 22 each form four channels 23, 23 ′ assigned to two diameters of the frame ceiling 18 that are perpendicular to one another. and 24 and 24 ', of which channels 23 and 23' on the one hand and channels 24 and 24 'on the other are in alignment with one another.
  • connection contact springs for the conductors are arranged in the interior of the socket body 11 and - in mostly one-piece assignment - the contact tabs for the lamp base.
  • a gap 28 which is narrower than the outer diameter of an insulated conductor. The gap 28 thus serves as a clamping gap for a conductor and provides its strain relief when the conductor is to be led through the channel 23 or 23 'to the conductor insertion openings 25.
  • the flange 17 In the circumferential direction, each offset by 90 ° to the notches 19 for the engagement of the latching hooks 21 of the dome D, the flange 17 each has a further notch 29.
  • This serves on the one hand to fasten the socket body 11 by means of a bayonet-type plug connection a light support plate, which will be described later.
  • a notch 29 is used to guide a conductor emerging from a socket insertion opening 25 on the outside of the socket body through a Z-shaped or S-shaped bend under the flange and, if necessary, to clamp it in the notch 29.
  • the notch 29 is assigned a narrowed section 30, which in the exemplary embodiment is designed as a jacket slot 31. A conductor can be clamped in this jacket slot 31.
  • the socket 10 can be fastened using the socket dome D.
  • This has an opening 33 on the top side, which is generally provided with an internal thread 34.
  • the socket D can be screwed to a lamp support tube or other lamp parts in this way.
  • the opening 33 serves at the same time for the passage of the two connecting conductors. After these have been inserted into the conductor insertion openings 25 and coupled to the contact terminals, the socket body 11 is latched with the permanently installed socket dome D.
  • a second possibility of fastening the socket body 11 is to screw it onto a fastening surface using the fastening openings 26.
  • the free end edges or surfaces of the web strips 22 and / or the sleeve-shaped collar 27 serve as a mounting system.
  • Such a type of fastening is shown schematically in FIG. 2 without the screws penetrating the openings 26 from the inside of the holder.
  • the part labeled 35 can e.g. be a pot-shaped lamp component made of wood.
  • the multiple deflection of the relevant serves as strain relief for the conductors 36 and 37 Conductor, in particular the deflection over the edge region of the flange 17 delimiting the notch 29.
  • the conductor arrangement clamped in the jacket slot 31 also occurs.
  • FIG. 3 illustrates a further possibility of fastening the same holder to a thin mounting plate 41 or the like, which could also be, for example, the bottom of an essentially pot-shaped lamp reflector.
  • the support plate 41 has an approximately circular cutout 42 with two diametrically opposed notches 43, the tabs producing the notches being deformed into catch hooks or under-grip hooks 44.
  • Each catch hook 44 is connected via a web 45 to the edge of the notch 43, while a free leg 46 which is angled at approximately 90 ° is bent back approximately parallel to the support plate plane 41.
  • the diameter of the circular sheet metal cutout 42 is about the protrusion of the flange 17 over the jacket of the section 16 smaller, on the other hand about so large that the substantially radially outwardly pointing edges 22 'of the web strips 22 can engage centering therein. If the holder body 11 is placed against the support plate 41 from the sheet metal side with the hooks 44, the legs 46 can engage in the notches 29 on the flange side. If the socket body is then rotated about its longitudinal axis relative to the support plate 41, the hook legs 26 undertake the flange and hold it Version firm. Of course, the distance between the groove formed between the leg 46 and the underside of the sheet approximately corresponds to the flange thickness.
  • tongues 47 which are slightly bent out on one side are cut into the luminaire plate and each insert with their free edges 48 into the notch 29 when these are screwed into the area of the tongues 47. In this way, securing against turning back of the socket relative to the light plate 41 is ensured.
  • the conductor guide can be easily in the manner shown, e.g. uses the channel 23 and presses the two conductors 36 and 37 into the conductor clamping grooves on both sides of the sleeve web 27.
  • a conductor guidance for example of the type shown in FIG. 2 and described using this type, is also possible, or a direct conductor feed from the top of the socket.
