Definitions
- the present invention relates to a revolving, low-voltage contact device suitable for being orientated according to a plurality of space directions, in particular for lighting equipment.
- the purpose of the present invention is of overcoming the drawbacks inhering in the prior art, by proposing a novel contact device which is capable of showing a very wide range of orientation positions, is completely free from flexible power supply cables, and is equipped with a reliable contact system.
- a revolving, low-voltage contact device suitable for being orientated according to a plurality of space directions, which is characterized in that it is constituted by a first contact element comprising two conductors, with said first contact element being suitable for being inserted, with possibility of removal, into a first conductor body suitable for rotating relatively to a longitudinal axis of said first contact element, with said first body a second, insulating body being rotatably associatable, which second, insulating body is equipped with a conductor plate on one of its base surfaces, and with two conductor terminals extending from a portion of one of the side surfaces thereof, with one of said terminals being connected with said conductor plate, electrical conducting linking means being furthermore provided, which are suitable for linking said first contact element, said first conductor body and said second conductor body with one another in such a way that said first body and said second body may integrally rotate as a whole relatively to said longitudinal axis of said first contact element, and said second body may
- At least one of said two conductor elements is a rigid conductor.
- said first contact element is constituted by a first, rigid, hollow conductor, inside which a hollow, insulating element is inserted, wherein inside said hollow, insulating element a second conductor is coaxially inserted, with said insulating element protruding beyond the ends of said first conductor and said second conductor protruding beyond the ends of said insulating element.
- said first, conductor body is constituted by a hollow cylindrical body with an open base provided with a perimetrical seat, and a tubular, conductor element is provided on the side surface of said first conductor body in connection with the interior of said first conductor body, which tubular, conductor element is suitable for housing said first contact element.
- Said second, insulating body is furthermore constituted by a hollow, cylindical body having an open base and a base with a through-bore running through it.
- said conductor plate is an annular plate positioned in correspondence of said through-bore.
- one of said two conductor terminals is connected with said annular plate, with the other one of said two conductor terminals having an end ending inside said through-bore.
- said linking means are constituted by a pin having a perforation at a free end thereof, and bearing a plate at its other end, with said plate being suitable for being inserted inside said open base of said second insulating body, with said pin running through said through-bore while keeping into contact with said one end of said other one of said two terminals, said free, perforated end being suitable for receiving an end of said second conductor element protruding from said insulating element, on said pin elastic means being furthermore provided, which elastic means constitute retainer means suitable for getting engaged between said plate and said base provided with said through-bore.
- said annular plate is suitable for being rotatably engaged inside said perimetrical seat provided in said first conductor body.
- a device according to the instant invention is generally indicated by means of the reference numeral 10.
- Such a device 10 comprises a first contact element 11 constituted by a hollow, cylindrical conductor 12 inside which an also hollow, insulating element 13 is coaxially inserted. Inside the interior of the insulating element 13 a second conductor element 14 is provided, which is so positioned that one of its ends protrudes outside the insulating element 13 which in its turn is slightly protruding outside said hollow, cylindrical conductor 12.
- the first contact element 11 can be inserted inside a first body 15 of cylindrical shape and with a hollow interior, made from a conductor material, so that only the hollow cylindrical conductor 12 is into contact with it; the body 15 is furthermore freely rotatable around the first contact element 11 and is equipped with a perimetrical seat 16.
- a second insulating, hollow, cylindrical body is associated, as indicated by the reference numeral 17.
- Such a body 17 is provided with a base 18 through which a through-bore 19 runs, and with an annular, conductor plate 20 positioned externally to the body 17, in order to get engaged inside said perimetrical seat 16.
- a first electrical terminal and a second electrical terminal extend; said electrical terminals are respectively indicated by the reference numerals 21 and 22.
- the electrical terminal 21 is connected, e.g., by means of a connection screw 23, with the annular conductor plate 20, and the electrical terminal 22, fastened to the body 17, e.g., by means of a second screw 24, ends inside the through-bore 19.
- a conductor pin 25 is provided.
- Said conductor pin 25 bears a bore 26 at one of its ends, and the other end thereof is equipped with a plate 27 which is suitable for being inserted inside the interior of the body 17.
- a helical spring 28 is furthermore installed, which supplies the necessary force for the unit according to the present invention to be kept assembled as a whole with possibility of revolutionary movements.
- the first contact element 11 is inserted inside the first body 15, and the second, insulating body 17 is placed into contact with the first body 15, causing the annular plate 20 to come to be housed inside the purposely provided seat 16, precisely provided on the body 15 for this purpose.
- the pin 25, bearing the spring 28 has to be inserted through the through-bore 19 in such a way that its bore 26 gets engaged with the end of the second conductor 14 of the contact element 11.
