Definitions

  • the invention relates to an incandescent lamp socket with a socket body on the connection side receiving conductor connection terminals and a socket which can be latched with it, essentially hood-shaped and surrounds the socket side of the socket body, which has openings in its base bounded by web strips, which cover the openings with openings in the socket dome coupled to the socket body of the socket body, under which the conductor terminals are arranged, with a strain relief for the cable being provided on the socket, at least part of which consists of an integrally-integrally connected arm with its leg end on the socket, which is designed at the free end as a clamp or carries a clamping tab, and wherein at least one resilient locking element, which interacts with this and cooperates with an abutment support, on the mounting dome for the releasable connection to a cutout t of a holder is provided, the locking member and abutment support each forming a support surface pointing towards the lamp side and inclined towards the socket body axis.
  • an incandescent lamp socket with a socket is known, from which the present invention is based in the preamble of claim 1.
  • This incandescent lamp holder can be coupled with a socket which can be releasably locked and which has a cantilever arm integrally molded onto it in the base area. This arm forms part of the strain relief for the connecting cable, which is completed by a clamp.
  • This arrangement enables easier assembly in that the socket body coupled to the socket dome also forms a one-piece, manageable assembly with the socket support, to which the strain relief is already attached.
  • the conductors can therefore be connected to the electrical connection terminals of the socket body and the cable can be fixed in the strain relief before the unit is connected to the lamp holder.
  • the holder has two locking elements in the form of spring tongues on the open side facing the lamp.
  • the frame carrier has a cutout with its own circumference corresponding approximately to the circumference of the dome of the cathedral, and the support surfaces provided on the latching members overlap edge regions of this cutout in the inserted position.
  • Each of the two identically designed locking members thus has both a spring tongue and a support abutment located on it.
  • the invention solves this problem in that a resilient locking member and an essentially rigid abutment support are formed diametrically opposite one another in the bottom region of the socket, the abutment support from the corner transition area of the dome to the underside of the arm and the locking member on the opposite side of the jacket than from the bottom area spring tongue pointing parallel to the socket are arranged so that the supporting surfaces of the spring tongue and abutment support and the outer sides of the web strips are arranged inscribed in a narrow rectangular outline, that the maximum cross-sectional dimension of the clamp-free arm section of the strain relief corresponds approximately to the width of this contour, the length of which exceeds the transverse projection of the clamp .
  • the maximum cross-sectional dimension of this component arrangement corresponds approximately to the width of the outline.
  • Another advantage of the bulb holder according to the invention is also its lower manufacturing costs, since only a spring-loaded latching element is necessary.
  • the arrangement of the strain relief and the coupling means on the dome is such that they are arranged on the outside of the base of the dome, that is, regardless of its circumference, in the light bulb socket according to the invention.
  • the socket equipped with the dome then only needs to be pushed through with the free end of the arm having the strain relief through the cutout of the socket support and possibly rotated until the abutment support arranged in the corner transition area between the dome coat and arm rests on a boundary edge of the cutout, whereupon then only the spring tongue protruding from the floor. the other, opposite cut edge needs to be clipped on.
  • the clamp-free arm section of the strain relief has a maximum cross-sectional width which essentially corresponds to the maximum width of the contour mentioned.
  • the "maximum cross-sectional width" is usually the diagonal dimension for a rectangular cross-section of the arm section.
  • the socket can therefore be rotated into the intended end position after the clamp has been passed through the cutout of the socket support corresponding approximately to this outline, without having to adjust the inside width of the cutout to the projection (A) of the clamp, which is given in the prior art was that the protrusion of the clamp was smaller than the diameter of the socket, that is also smaller than the frame carrier cutout.
  • the openings in the socket dome are arranged essentially within a space delimited laterally by the (imaginary) extensions of the arm side walls. This easily results in the possibility of laterally delimiting the openings in the socket dome which represent conductor insertion openings and which can also pass out through the cutout in the socket carrier, namely when the space limitation in the base region of the socket dome is formed by web strips molded onto it. whose outer surfaces facing away from each other are at a distance from each other, which also corresponds approximately to the maximum cross-sectional dimension of the arm section. These web strips then also form with their outer surfaces a guide and centering for the holder of the dome in the mount cutout.
  • the bulb holder consists of a socket body 10 and a dome or cap-like cap dome 11 on the connection side thereof.
  • the socket body 10 which is usually made of porcelain, contains a screw thread 12 for the base of an incandescent lamp and houses connecting terminals 13 for the electrical conductors 14 and 15 of a connecting cable 16.
  • the socket dome 11 which overlaps the connection side of the socket body 10 to approximately half the axial length, is made of plastic. It has a bottom 17 and an adjoining circumferential jacket 18. At two diametrically opposite points, the resiliently expandable socket dome 11 has locking cams 19 for plug-in coupling with the socket body 10, which is provided with counter-locking cams 20 at corresponding points.
  • An arm 21 is integrally formed on one side and integrally connected to it on the outside of the bottom of the socket dome 11 and carries a clamp 23 at its free end as a strain relief 22.
  • the strain relief 22 comprises a transverse web 25 attached to the free end of the arm 21 and having a transverse groove 24, with which a clamping piece 26 with a clamping rib opposite the groove 24 27 is clamped from the other side of the cable 16. This is done with the help of self-tapping screws, not shown, the engagement bores of which are designated 58 in FIG. 2.
  • the clamp body 26 has an elongated arm 28 which has engagement lugs 29 at the free end for insertion into corresponding openings on the bottom side of the dome 11.
  • the clamp part 26 with the section 28 thus forms a cover on the outside of the floor.
  • side legs 30 (Fig. 2) are attached, which cover the side walls located on the arm 21, so that the arm 21 forms a self-contained conductor guide channel with the cover 26/28.
  • the cable 16 is then completely covered from the entry 31 into the clamp 23 to the outside.
  • a support surface 32 is formed in the exemplary embodiment as an inclined surface, which may be cross-corrugated. It is part of an essentially rigid abutment 33.
  • the support surface 32 diametrically opposite is a further support surface 34 with an opposite inclination.
  • this is part of a locking element 35 arranged in the extension of the domed surface, which is designed here as a resilient locking tongue 36. With its free end, it points away from the bottom 17 of the socket dome 11.
  • the support surfaces 32 and 34 serve to abut on edges 37, 38 of the cutout 48 (FIGS. 3, 7) of a frame carrier 39. The length of this generally narrow rectangular cutout corresponds to the distance in FIG.
  • the openings 42 arranged in the base dome floor 17 for the passage of the conductors 14 and 15 are arranged within a narrow one of the extensions of the side walls 30 of the arm section 21 or of the cover 28 connected to it. In the floor area of the cathedral, this zone is delimited by two web strips 43 and 44. Their maximum outer width 45 again corresponds approximately to the narrow inside width of the cutout of the frame carrier, so that the web strips 43 and 44, acting on the long sides of the cutout, simultaneously serve for centering.
  • FIG. 3 to 6 show the mounting of an incandescent lamp holder in a narrow rectangular cutout of a holder 39.
  • the holder 39 here consists of a U-shaped bracket with two legs 46 and a web 47 connecting them, in which the cutout 48 is provided .
  • the cutout 48 is narrower than the maximum transverse projection A of the clamp 23, but longer than this. 3 is first inserted through the cutout with the clamp 23 oriented in the longitudinal direction of the cutout until the arm section free of clamps comes to lie in the cutout 40 in the area of the cross section 40 (FIG. 1) (FIG. 3) Fig. 4). Now the frame is rotated on the one hand about its transverse axis 49 and on the other hand about its longitudinal axis 50 into the position shown in dashed lines in FIG. 4 (arrow 51). Then the abutment support 33 is placed on the one narrow edge of the cutout 48, and the entire mount is pivoted upwards in the direction of arrow 52 (FIG.
  • FIG. 7 schematically shows a top view of the bracket web 47 serving as a frame carrier 39 with the cutout 48 contained therein.
