Definitions

  • the invention relates to an incandescent lamp socket with a socket body and a socket essentially made of insulating material radially thereon with respect to the lamp axis, as well as with a screw thread for the lamp on the socket body side, with a contact protection collar adjoining the screw thread on the lamp side and with lamp contacts and conductor connection terminals which are located within the Socket body and / or the socket base are arranged in front of the back wall.
  • the invention is therefore based on a prior art, as described for example in DE 92 14 524 U1.
  • the bulb socket is snapped into a section of a light part with its socket base first. Therefore, the assembly of the bulb holder in a reflector, that is, a hollow body closed up to the lamp assembly opening, causes certain problems or requires installation aids.
  • a pocket-like channel is formed on the previously known incandescent lamp socket, which can be accessed from the lamp assembly side of the socket by means of an auxiliary assembly tool such as a screwdriver. With the help of this tool, the bulb holder is guided and moved for the purpose of assembly. No further explanation is required that this is cumbersome and therefore in need of improvement.
  • the invention is therefore based on the object of specifying an incandescent lamp holder, which in this respect Simplified installation on luminaire parts, especially in narrow luminaire housings or reflectors, permitted.
  • the bulb holder thus primarily and essentially characterized in that the socket body and shock protection collar consist of two separate components, the socket body essentially ends with the screw thread on the lamp side and in each case close to the edge of the ring body of the shock protection collar and locking means for connecting the parts to one another are arranged on the socket body.
  • DE 28 28 560 B2 shows an incandescent lamp holder with a holder (a so-called holder dome) and a protective sleeve.
  • the protective sleeve which is latched to the socket after it has been previously attached to the socket body, forms a two-part socket support together with the socket.
  • the purpose of the protective cuff is to envelop the socket body, which is generally made of porcelain, in full height and to protect it from external damage. At the same time, it gives the bulb socket a homogeneous, external appearance by enveloping the porcelain socket in its full height.
  • the socket body itself is not treated constructively in any way here, and the protective cuff does not serve as a contact protection collar ensuring the electrical safety of the socket.
  • the present invention therefore, there is only the formal commonality of the use of a protective sleeve, but in an incomparable structural design and arrangement as well as the objective.
  • the separable design of the socket body and contact protection collar which can be separated for simplified assembly, in the subject matter of the invention offers the further essential advantage that the incandescent lamp holder together with the mains conductor and even possibly including a lamp joint, lamp foot or the like. can be completely pre-assembled or assembled. This allows the luminaire body to be selected with regard to the type, shape and / or color currently desired immediately before the final assembly of a luminaire.
  • the wall cutout extending over a large part of the luminaire body circumference could no longer be easily produced with a simple punch cut.
  • a particularly clever plug-in / snap-in connection between the socket body and the contact protection collar results in connection with a rear grip collar that runs around the edge as a latching means on the socket body, in particular when at least two, preferably at least three, self-resilient latching hooks are distributed over the circumference of its rim as latching means on the touch protection collar. which are expediently cut out of the wall of the contact protection collar not only in the sense of material savings, but also for the shortest possible and in this respect particularly clever arrangement.
  • the latching means on the socket body and / or the latching hooks and / or the support shoulder (s) of the contact protection collar being provided with sliding, spreading and / or centering bevels so that a self-centering, Automatically guided 'docking' of the contact protection collar results as soon as it is pressed against the facing frame body edge with its front edge leading during the assembly movement.
  • the contact protection collar 14 is a separate component from the socket body 11. That is why there is Special feature of the socket body 11 is that its lamp-side termination essentially ends with the screw thread 15 for the base of a lamp, not shown.
  • An incandescent lamp socket 10 with a socket body 11 which is extremely shortened in this way alone does not meet the VDE regulations on contact safety, but only with the contact protection collar 14 attached to it.
  • the socket base 12 extends essentially radially to the socket body 11.
  • the component which projects the most in the direction of the axis 16 is a flange designated by 17 of - Also provided on the opposite side not visible in the drawing - locking means arrangements 18/19 releasably clipped to the mounting base 12 holding part 13.
  • this is a joint part of an at least two-part joint arrangement for pivoting and / or rotating the lamp body relative to its support arm .
  • the socket 10 can be inserted into the mounting cutout 21 of the lamp body 22 without the shock-proof collar 14 with the therefore extremely short socket body 11 first in a plug-in orientation rotated by 90 ° to the later position of use and can be brought into the position of use by subsequent rotation (arrow direction 23 ).
  • the invention assumes that the bulb holder 10 is one of the widespread size E27 or the size E26 used in individual countries and that with the 'cut back' of the socket body 11 except for the necessary short dimension of the socket body 11 due to the screw thread 15 in the area to be inserted now in the axial extent (direction along the lamp axis 16) is significantly shorter than its outer diameter.
  • plug-in and latching means comprise an optionally lockable slip-on groove 24 on the front of the socket for pushing onto the front edge 26 of the cutout 21 in the lamp body 22 and a latching pawl 25 which, when pressed into the cutout 21, self-locking on the rear edge 27 of the section 21 occurs after the bulb holder 10 has been rotated following the insertion of the holder body 11 into the reflector 22 by a quarter circle (arrow 28).
  • the flange 17 remaining on the outside of the lamp body 22 (see in particular FIG. 4) completely conceals the cutout 21 and possibly even seals it.
  • the touch protection collar 14 already mentioned is necessary in order to give the bulb holder 10 the required electrical safety. It is designed as a component which is separate from the socket body 11, but can be firmly connected to it, in particular by means of a plug-lock.
  • This plug connection is provided in the mutually facing end or edge regions 30, 31 of the socket body 11 and the contact protection collar 14 and, in the exemplary embodiment, as a latching means on the socket body 11 comprises a rear engagement collar 32 running over its jacket and as a (counter) latching means on the contact protection collar 14 three ( Fig. 1 to 3) or five (Fig. 4) self-resilient locking tongues 33, the hooks 34 are intended at the free ends for snapping behind the rear grip collar.
  • the contact protection collar 14 is placed against the end face 30 of the holder body 11 in the lamp axis direction 16 and pressed on until the catch hooks 33, 34 reach the locking position and the contact protection collar 14 is supported with support shoulders 35 against the front edge 30 of the holder body 11.
  • the support shoulders 35 are designed as alternately offset support surfaces arranged with the latching hooks 33, 34.
  • the spring tongues 33 are designed to be quite short and with only a slight protrusion over the edge 31 of the contact protection collar 14, which results from the cut out of the jacket of the contact protection collar 14.
  • the snap-on paths are thus advantageous, which considerably simplifies handling when connecting the contact protection collar 14 to the socket body 11.
  • the design of the locking means on the socket body side, of the engagement collar 32 as a circumferential ring body, which does not require any special circumferential orientation of the contact protection collar relative to the socket body 11 also contributes to this.
  • the connecting conductors designated 20 can be completely preassembled before a selected lamp body 22 is assembled with the socket arrangement.
