Definitions

  • the present invention relates to sockets intended to support and energize, a tubular lamp with axial caps, of the incandescent type.
  • Known sockets of the above kind arranged to exert an axial thrust on the lamp bases so that the latter is held by pinching between the sockets; in general, the means exerting such a clamping effect are constituted by springs simultaneously ensuring an electrical connection with a supply circuit.
  • Patent US-A 2,447,676 (Bryant Electric Company) issued on August 24, 1948 teaches a socket comprising a hollow monobloc support with an opening forming an end-of-travel stop at an insulating piston plate.
  • a spring arranged in the hollow support has the function of pressing on an inner face of the piston plate a contact disc placed opposite an opening formed in the piston plate for the passage of a lamp contact; the spring also has another function which is to establish an electrical connection with a contact blade.
  • one end of the lamp is first engaged in a support, then after compression of the spring, the other end can be engaged in another support suitably spaced from the previous one.
  • Patent US-A 2656521 (Silvania Electric Products) issued on October 20, 1953 teaches a support for fluorescent tube, whose provisions are very similar to US-A 2,447,676 with the difference that the contact piece - whose role is similar to that of the piston plate of the aforementioned patent - is here, protruding with respect to the hollow cylindrical element.
  • the present invention relates to a socket of simple production, and whose configuration prevents the operator from having access to the lamp bases, as well as to the electric current supply pads, so that the operator can act safely even if the electric current supplies are live.
  • a safety socket for a tubular lamp with axial caps comprising elastic means disposed between the lamp base and a base, these means being adapted to hold the lamp by a pinching effect exerted axially on the caps, as well as suitable means to be connected to an electrical supply circuit, is characterized in that it comprises a cap comprising two parts assembled by telescopic mounting, hereinafter called for convenience case and sleeve, said case being provided removably nestable in a base , said cap housing elastic means, while means associated with both the cap and the base are adapted to establish an electrical connection with a supply circuit.
  • a safety socket according to the invention comprises a cap indicated generally at 9 comprising a first part 10 forming a housing with a second part 11 forming a sleeve, these two parts being assembled by telescopic mounting and at spacing by elastic means constituted by the occurrence by a spacer spring 13; the socket also includes a base 14 intended to be fixed to any support schematically shown in 15.
  • the sleeve 11 of the cap has in the exemplary embodiment shown, without limitation, a generally tubular shape with quadrangular section with open ends and it is adapted to be engaged in the housing 10 without significant play; the sleeve 11 advantageously comprises on its inner faces of the longitudinal ribs 20 serving to guide the base 21 of the lamp 22, it will be noted that this part of the cap could be devoid of such ribs so that this part 11, depending on whether it has ribs or not, can receive a lamp with bases of different diameters.
  • the ribs 20 extend locally inside the sleeve 11 by having a truncated end 20A, intended to form a stop for the lamp 22.
  • this sleeve On the opposite side where the sleeve 11 receives the lamp, this sleeve has, on each side, a notch 25 intended to form recesses to allow the insertion of the spring 13 inside said sleeve 11, so that a end of this spacer spring 13 rests on the bottoms 25A of the notches 25.
  • the sleeve 11 On one side, the sleeve 11 has a longitudinal opening 26, the usefulness of which will appear later.
  • the housing 10 of the cap has the appearance of a tubular element closed at one end by a bottom 28, the other end being open to allow engagement of the sleeve 11.
  • the housing 10 has a lower face or base 29, and an upper face 30; in the lower face is made a hole 31, while the upper face has projecting sides and a gripping means 32 intended to be projecting relative to the base 14; it will be noted that the aforementioned gripping means is located between two support planes 33, 34, (see also fig. 8) whose usefulness will appear later.
  • a longitudinal slot 35 is provided to allow the passage of a first electrical connection element indicated generally at 36.
  • Such a first electrical connection element is in the form of a blade 36 having a flat section 36A extended by a heel 36B with a return 36C; the planar section 36A being intended to be pressed by the aforementioned spring 13, on the bottom 28 of the housing 10, while the heel 36B is shaped to project from the outside face of this bottom 28.
  • the sleeve 11 When the sleeve 11 is engaged in the housing 10, after the first contact element 36, the spacer spring 13, and an element capable of establishing an electrical connection between the end face of the lamp base and the aforementioned first contact element, such an element being, in the example shown constituted by a spring 12 coaxial with the spacer spring 13, the sleeve 11 is assembled by a sliding assembly to the housing 10 to form the cap 9; for this purpose, a rivet 40 is placed in the hole 31, the rod 40A of which is adapted to cooperate with the longitudinal slot 26 formed in the sleeve 11.
  • the cap 9 thus formed is intended to be associated with a lamp base, (for the sleeve 11 of the cap) and in the base 14 (by the housing 10 of the cap); this base comprises a base 50 with holes for fixing 52 to a support, which base is bordered by sides extending vertically respectively lateral 53, 54, and bottom 55.
  • a cavity 57 adapted to receive a second contact element constituted by a pad 58; the bottom of this cavity has a hole 59 provided to allow the passage of a conductor 80.
  • the cavity 57 is able to allow the setting of the pad 58 which comprises a screw 58A accessible from the inside of the base, this screw ensuring the connection of the conductor 80 to said pad 58.
  • the bottom side 55 has at its free upper edge a central notch 65 on either side of which ears 66, 67 are respectively formed.
  • each base 21 of a lamp 22, is equipped with a cap 9, as described above, and the caps are each engaged in a base 14 fixed to any support, such as a strip 15, this the latter is however not essential, the bases 14 can be fixed directly on a support.
  • each contact pad 58 is connected with a conductor 80 connected to an electrical supply circuit, and that the electrical connection between these contact pads and the corresponding caps 21 of the lamp 22 is ensured through the blade 36 and the preferably conical contact spring 12, while the spacer springs 13 ensure the maintenance of the lamp by axial pinching because these are compressed when the caps 9 are inserted inside the bases 14.
  • the sleeves 11, housing 10, and base 14 being made of insulating moldable material, the bases 21 of the lamp are protected, at the same time as they are inaccessible to the operator, given that they are capped in their entirety by said caps.
  • the lamp 22 is engaged from the front between the bases.
  • each cap 9 exerts an axial pressure (arrows F) on each cap 9 so as to reduce, by compression of the spring 13, the length L to a length less than that L 'comprised between the bases, which has for simultaneous effect of bringing the free ends of the contact springs 12 to the end face of the caps 21; that said, the lamp can easily be engaged between the bases until the lower faces 29 of the housings 10 come into abutment on the bases 50 of the bases 14.
  • the pressure can be released if this has not been done during insertion, the release of the pressure on the housings 10 of the caps having the effect of releasing the spacer springs 13 and ensuring contact of the heels 36B with the studs 58. Simultaneously the lamp is held between the bases 14 under the effect of the spacer springs 13. Note that the heels 36B are applied to the studs 58 by the action of the spacer springs 13, thereby establishing the electrical connection, and this, at the very end of fitting the caps into the bases.
  • the lamp is tilted around a pivot axis XX (see also fig. 8) formed by the cooperation of the support planes 33, 34, formed in the housing 10 of the cap, with the edges free ears 66, 67, formed in the base.
  • the lamp is presented inclined with respect to the bases 14 and any of the caps are inserted into a base; a push is then exerted (arrow F1) on the free cap at the same time as it is inserted into its corresponding base; we note that the heels 36B thus inserted provide no electrical connection with the circuit as long as the caps 9 are not brought into abutment in their respective bases.
  • a clearance J is formed between the bottom wall 28 of the housing 10 of the cap and the bottom side 55 of the base; such a clearance being obtained by the cooperation of the heel 36B with the stud 58 so that one is assured of a good electrical connection at the contacts.
  • the pad 58 is confined in a cavity while being set back with respect to the internal face of the bottom side 25 of the base so that this pad is also almost inaccessible even when the cap 9 is removed.
  • the invention is not limited to the embodiment chosen and shown, which is on the contrary subject to modifications without departing from the scope of the invention, this is how the contact elements could have a configuration. different and be arranged in another location, which will in any event be as distant as possible from the hinge axis XX, the pad 58 being provided set back from a cavity which receives it.
  • the cap and the base could have a different section from that shown, for example circular or other, without the general provisions of the parties in question being significantly modified.
