Definitions

  • the present invention relates generally to sockets intended to receive a light bulb, for support and power of it.
  • sockets which comprise, in particular, on the one hand, a body, in whose grip the connection terminals required for connection of a clean electrical cable to the supply of the electric bulb, and, on the other hand, by measuring security, to avoid third parties any risk of coming to touch such terminals of connection even though they may be live, a cap, generally bell-shaped, which, on the side of its outlet, at least partially covers the body, and which, at a distance from its outlet, has a clean opening for the passage of the electric cable.
  • this cap is in one piece.
  • the partition affects not only the cap but other elements of the socket which also happen to be in one piece with this cap.
  • the present invention generally relates to a arrangement to facilitate the installation of sockets of the kind mentioned above, without the above drawbacks and without the need to associate with their cap any element other than one of those already participating in the constitution of such a socket.
  • a bulb socket electric of the kind comprising, in particular, a body, in the grip of which are installed the connection terminals necessary for the connection of a electric cable, and a cap, generally bell-shaped, which, on the side of its outlet, at least partially covers the body, and which, at a distance from its outlet, has a clean opening for the passage of the electric cable
  • this socket being generally characterized in that, on the one hand, the cap has, laterally, an opening, which extends continuously from its opening at its outlet, and which is specific to its engagement on the cable electric even though it is not yet in place on the body, and, on the other hand, the body is equipped with a cover, which at least partially obscures the opening of the cap when it is in place on it.
  • the cap can advantageously be put in place on the electric cable even after connecting it to the body of the socket, thanks to the opening which it presents over its entire height, and, jointly, it is taken advantage of the body of the socket to then conceal its opening.
  • This cap can therefore advantageously be made in one taking advantage of the simplicity of manufacturing and operations installation, and for the closing of the opening which it contains, necessary for compliance with the safety conditions to be ensured, it is advantageously need no other element than one of those already present elsewhere in the socket.
  • the socket 10 is of the kind comprising, in particular, on the one hand, a body 11, in whose right-of-way are the connection terminals 12 necessary for the connection of an electric cable 13, which is shown diagrammatically in broken lines in Figure 2, and, on the other hand, a cap 14, shaped general bell, which, on the side of its outlet 15, covers at least partially the body 11, being axially wedged relative to this body 11, and which, at a distance from its outlet 15, has an orifice 16 specific to the passage of the electric cable 13.
  • This socket 10 does not fall, in its entirety, from the present invention, it will not be described in full detail here.
  • this jacket 18 is adapted, for example, to receive an electric bulb with bayonet base.
  • the shirt 18 forms, annularly, on the side of the cap 14, a strip 19, and it comprises, in withdrawal from this strip 19, a threaded section 20 in favor of which it associated with it, for example for fixing the assembly to any lampshade not shown, a skirt 21.
  • the shirt 18 forms, internally, at the base of its strip 19, a transverse shoulder 22, for the axial support of the body 11.
  • the cap 14 comprises, laterally, a opening 24, which extends continuously from its orifice 16 to its outlet 15, and which, as will be described in more detail later, is specific to its engagement on the electric cable 13 even though it is not yet in placed on the body 11, and, jointly, the body 11 is fitted with a cover 25, which at least partially obscures the opening 24 of the cap 14 when this one is in place on him.
  • the opening 24 of the cap 14 extends substantially along a radial plane of this cap 14, and the lips 26 of this opening 24 are substantially parallel to each other.
  • the cap 14 is fixed axially relative to the body 11 by latching means 27, 28 involving a simple axial engagement of this cap 14 on this body 11.
  • latching means 27, 28 intervene between the cap 14 and the jacket 18 on which the body 11 axially supported.
  • these snap-fastening means 27, 28 comprise, on the one hand, on the cap 14, two snap tabs 27, which, arranged in diametrically positions opposite to each other, each locally extends the cap 14 beyond its outlet 15, and which, each shaped internally hooked, are elastically deformable, and, on the other hand, on the sleeve 18, two notches 28, which, each arranged respectively in correspondence with the locking tabs 27, each intervene at the favor of a notch 29 provided locally for this purpose on the strip 19 of this shirt 18, and on which the latching tabs 27 are clean to come and crochet.
  • the cover 25 equipping the body 11 is a rib on which the cap 14 is capable of fitting through its opening 24.
  • the body 11 has, at its base, a sole 30, by which it is able to bear axially on the jacket 18, and, more precisely, on the transverse shoulder 22 that internally presents this one.
  • the body 11 is therefore partly fitted in shirt 18.
  • the rib forming the cover 25 fitted to the body 11 protrudes from the back of a flange 33, which extends substantially perpendicular to its sole 30, and on the other side of which there are connection terminals 12.
  • the outer surface 34 of the rib forming the cover 25 fitted to the body 11 is like the external surface 35 of the cap 14.
  • the outer surface 34 of the rib forming the cover 25 equipping the body 11 is in continuity with the outer surface 35 of the cap 14 when this cap 14 is in place on the body 11.
  • the rib forming the cover 25 equipping the body 11 a lateral flanks 36 which are substantially parallel to each other, and the distance separating one from the other these lateral flanks 36 is substantially equal at the distance separating one from the other the lips 26 from the opening 24 of the cap 14 while being slightly less than this distance.
  • the cover 25 fitted to the body 11 is in one piece with this one, by forming of molding only one and the same piece with this body 11.
  • the body 11 is assembled in the workshop and of the jacket 18, with incorporation of the safety shutter 23 between them, and, for safety reasons, this assembly is done in a non-removable manner.
  • this assembly uses latching means, which operate inside the jacket 18, in alignment with the notches 29 thereof.
  • socket 10 For the implementation of the socket 10 according to the invention, it can by example proceed as follows.
  • connection terminals 12 that comprises the body 11, the electrical conductors constituting it being each individually brought into engagement with one of these terminals of connection 1 2.
  • the cap 14 is engaged, laterally, by its opening 24, on the electric cable 13, as shown schematically by the arrow F1 in Figure 2, until this electrical cable 13 aligns with its orifice 16.
  • the cap 14 is engaged axially on the body 11, along the arrow F2 in FIG. 2, by sliding along the electric cable 13, until, by its snap tabs 27, it comes in engagement with the shirt 18.
  • the cap 14 carries by its outlet 15 on the edge of the strip 19 of the shirt 18.
  • the cap 14 comprises, along at least one of the lips 26 of its opening 24, on at least part of its height, a return 38, which is directed inward, and which, when in place on the body 11, is inserted between the rib forming the cover 25 fitted to this body 11 and a stop 40 which the body 11 has at distance from this rib.
  • the cap 14 has a return 38 along each of the lips 26 of its opening 24, and this return 38 extends over most, at least, of its height, counting from its outlet 15.
  • the body 11 has a stop 40 on each side of the rib forming the cover 25 which equips it, and this stop 40 extends parallel to this rib, like a cheek.
  • the two stops 40 thus presented by the body 11 form, overall, a convergent 41 at their leading end, that is to say on the side opposite the sole 30, to facilitate the engagement of the cap 14.
  • these stops 40 protrude from the flange 33 of the body 11.
  • the cap 14 is wedged axially with respect to the body 11 by screwing means 42, 43 involving a rotation with respect thereto.
  • these screwing means 42, 43 comprise, on the one hand, on the cap 14, a tapped section 42 provided on the internal surface of this cap 14 in the immediate vicinity of its outlet 15, and, on the other hand, on the jacket 18, a complementary threaded ring 43 of the tapped section 42 of the cap 14.
  • the cover 25 equipping the body 11 then extends radially set back relative to the cap 14, to allow the rotational movement required by the latter for its screwing.
  • the cover 25 fitted to the body 11 is a rib projecting from the flange 33 of this body 11.
  • this cover 25 has a width greater than the width of the opening 24 of the cap 14.
  • the cap 14 has, at level of its orifice 16, on the side opposite its opening 24, a notch 44 allowing an adapter 45 to be blocked therein in rotation when such an adapter 45 must be provided to allow the socket 10 to be fixed to any threaded support rod, not shown.
  • an adapter 45 can also be used when, as described with reference to Figures 1 to 5, the cap 14 is wedged axially with respect to the body 1 1 by latching means 27, 28.
  • the cover fitted to this body can just as well come to project more or less on this external surface.
  • the headband allowing the cap snap could just as easily be integrated into the body.
  • the field of application of the present invention extends by elsewhere advantageously to any type of socket, and, in particular, to that of the sockets in which the body and the shirt form a part of a in one piece, as can be the case for example when no shutter security is provided.
