Definitions

the present invention relates generally to bushings for receiving a light bulb, for mounting and feeding of it.
bushings which comprise, in particular, on the one hand, a body, in the grip of which are implanted the connection terminals needed to connect a clean electrical cable to the power supply of the light bulb, and, on the other hand, by measure of security, to avoid to third parties any risk of coming to touch such terminals of connection even though they may be energized, a hood, 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 orifice to the passage of the electric cable.
this cap is in one piece.
the present invention generally relates to a provision to facilitate the installation of sockets of the type mentioned above, without the above disadvantages and without the need to associate with their hood any other element than one of those participating already in the constitution of such a socket.
a socket for a bulb electrical device of the kind including, in particular, a body, in the grip of which the connection terminals required for connection of a electric cable, and a cap, generally bell-shaped, which on the side of its outlet, covers at least partially the body, and which, at a distance of its outlet, presents a clean orifice to the passage of the electric cable,
this bushing being generally characterized in that, on the one hand, the cap has, laterally, an opening, which extends continuously from its orifice at its outlet, and which is peculiar to its engagement on the cable electric even though it is not yet in place on the body, and other the body is equipped with a cover, which at least partially obscures the opening of the cap when it is in place on him.
the cap can advantageously be in place on the electrical cable after even connecting it to the body of the socket, thanks to the opening that it presents on all its height, and, together, it takes advantage of the body of the socket to then obscure its opening.
This cap can therefore be advantageously made of a single taking advantage of the simplicity of manufacture and operations installation, and, for the closure of the opening it contains, necessary for the respect of the security conditions to be ensured, it is not need no other element than one of those already present elsewhere in the socket.
the bushing 10 is of the kind comprising, in particular, on the one hand, a body 11, in the grip of which are implanted the connection terminals 12 necessary to connect an electric cable 13, which is schematized in broken lines in FIG. 2, and, on the other hand, a cap 14, shaped bell, which, on the side of its outlet 15, covers at least partially the body 11, being wedged axially with respect to this body 11, and which, at a distance from its outlet 15, has a hole 16 specific to the passage of the electric cable 13.
This bushing 10 in the usual way, is complete, for the essential, by a shirt 18, in which the light bulb, no represented, to put in place must be introduced by its pellet.
this jacket 18 is adapted, for example, to receive a bayonet cap light bulb.
the liner 18 forms, annularly, on the side of the cap 14, a band 19, and it comprises, in withdrawal from this strip 19, a threaded section 20 through which it associated with it, for example for fixing the assembly to any one shade not shown, a skirt 21.
the liner 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 peculiar to its commitment on the electric cable 13 even though it is not yet in placed on the body 11, and, together, the body 11 is equipped with a cover 25, which at least partially obscures the opening 24 of the cap 14 when this one is up 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 wedged axially relative to the body 1 1 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 liner 18 on which the body 11 takes axially support.
these latching means 27, 28 comprise, on the one hand, on the cap 14, two latching tabs 27, which are arranged diametrically opposed to each other, extend each locally cap 14 beyond its outlet 15, and which, each conformed internally hook, are elastically deformable, and, secondly, on the shirt 18, two notches 28, which, each arranged respectively in correspondence with the latching 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 lugs 27 are clean to come get hooked.
the cover 25 equipping the body 11 is a rib on which the cap 14 is able to fit through its opening 24.
the body 11 presents, at its base, a sole 30, by which it is able to bear axially on the liner 18, and, more precisely, on the transverse shoulder 22 that internally this one.
the body 11 is therefore partly interlocked in the shirt 18.
the rib forming the cache 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 the connection terminals 12 intervene.
the outer surface 34 of the rib forming the cover 25 fitted to the body 11 is in the image of the outer 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 the cap 14 is in place on the body 11.
the rib forming the cover 25 equipping the body 11 has side flanks 36 which are substantially parallel to each other, and the distance separating one of the other side flanks 36 is substantially equal at the distance separating one from the other the lips 26 of the opening 24 of the cap 14 while being slightly less than this distance.
the cache 25 equipping the body 11 is in one piece with this one, molding only one and the same piece with this body 11.
this assembly implements latching means, which intervene inside the shirt 18, in alignment with the notches 29 thereof.
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 FIG. 2, until this electric cable 13 aligns with its orifice 16.
the cap 14 is engaged axially on the body 11, along the arrow F2 of Figure 2, by sliding along the electric cable 13 until, by its latching lugs 27, it comes engaged with the shirt 18.
the cap 14 carries by its outlet 15 on the edge of the strip 19 of the shirt 18.
the cache 25 equipping this body 11 occult then completely the opening 24 of this cap 14, by restoring moreover perfectly continuity of it.
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 inwards, and which, when in place on the body 11, fits between the rib forming the cover 25 equipping this body 11 and a stop 40 that the body 11 presents to distance from this rib.
the cap 14 presents 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, from its market 15.
the body 11 has a stop 40 on each side of the rib forming the cache 25 which equips it, and this stop 40 extends parallel to this rib, like a cheek.
the two abutments 40 that the body 11 thus presents form, overall, a convergent 41 at their leading end, that is to say on the opposite the sole 30, to facilitate the engagement of the cap 14.
these stops 40 project on 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 relative thereto.
these screwing means 42, 43 comprise, on the one hand, on the cap 14, a threaded section 42 provided on the inner surface of this cap 14 in the immediate vicinity of its outlet 15, and, on the other hand, on the liner 18, a complementary threaded ring 43 of the threaded section 42 of the cap 14.
the cover 25 equipping the body 11 then extends radially recessed relative to the cap 14, to allow the rotational movement required for it to screw.
the cache 25 equipping 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 opposite side to its opening 24, an indentation 44 to block in rotation an adapter 45 when such adapter 45 must be provided to allow the attachment of the socket 10 to any threaded support rod, not shown.
the cache 25 equipping this body 11 completely obscures its opening 24, although then be radially recessed relative thereto.
an adapter 45 can also be implemented 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 equipping this body can also come to more or less project on this external surface.
the strip allowing the latching of the cap could just as easily be integrated into the body.
the field of application of the present invention extends advantageously to any type of socket, and in particular to that of sockets in which the body and the shirt form a piece of a alone, as may be the case for example when no shutter security is not provided.
