Definitions

  • the present invention relates to an element for connecting a reticular shielding coaxial cable for taps, plugs and the like, and to a method of manufacture thereof.
  • coaxial electrical cables especially those intended for being crossed by high frequency signals, such as shielded cables for television antennas or those suitable for microphone transmission signals, require a suitable protection, that is, proper shielding of the electromagnetic waves that are always present in the cable and in the environment, and which are often cause of noises and/or alterations both for the signal contained therein and for the outer environment.
  • the shielding generally consists of a braiding or mesh made up of thin copper wires that completely surrounds the electrical conductor that carries the signal and is kept insulated from the conductor by a sheath of insulating material arranged coaxially outside the conductor.
  • the shielding mesh must exhibit a regular arrangement of the component wires to keep the characteristic impedance of the coaxial cable constant.
  • the latter provides to the separate clamping of the central cable and of the shielding braiding of the coaxial cable through flat terminals that cause a flattening thereof, which changes the cylindrical geometry of the coaxial cable itself.
  • some known connecting elements further comprise a box body inside which there is seated an electronic circuit on which the contacts to the upstream coaxial cable and to the downstream plug are preassembled.
  • the technical task of the present invention therefore is to provide an element for connecting a reticular shielding coaxial cable for taps, plugs and the like, and a relevant method of manufacture thereof, which should allow eliminating the technical disadvantages of the prior art.
  • an object of the invention is to provide an element for connecting a reticular shielding coaxial cable for taps, plugs and the like, which should not introduce dispersion and/or noises to and from the outer environment and which should not alter the transmission signal.
  • Another object of the invention is to provide an element for connecting a reticular shielding coaxial cable for taps, plugs and the like, having a very simplified structure which should minimise the attenuation of the transmission signal flowing therethrough.
  • another object of the invention is to provide an element for connecting a reticular shielding coaxial cable for taps, plugs and the like, which should be easy to manufacture and assemble and which should have competitive costs as compared to what is currently available on the market.
  • an element for connecting a reticular shielding coaxial cable for taps, plugs and the like characterised in that between an input terminal and an output terminal thereof, it exhibits a coaxial transmission line that develops in continuity with said coaxial cable.
  • the present invention also discloses a method for manufacturing an element for connecting a reticular shielding coaxial cable for taps, plugs and the like, characterised in that it consists in forming a signal conductor by die casting or shearing and bending from a rolled band of a material, applying an electrically insulating coaxial coating thereto, forming an electromagnetic shielding body by die casting or shearing and bending from a rolled band of a material comprising at least two shells internally defining an impression of said signal conductor, placing said signal conductor between said shells and joining said shells.

  • Conductor 5 exhibits an electrically insulating coaxial coating 6 seated in an impression 7 thereof obtained into an electromagnetic shielding body 8.
  • the transmission line comprises a signal conductor in a single piece that electrically connects the input terminal 2 directly to the output terminal 3.
  • Such connection is direct, meaning that it does not require the interposition of any electrical circuit or electrical connecting plate, between the input terminal 2 and the output terminal 3.
  • the transmission line 4 has a perfectly adapted morphology, thanks to which it minimises the attenuation of the flowing signal.
  • the signal conductor 5, as well as body 8 are obtained through die casting of an alloy, such as the so-called 'Zama' (Zn+Al+Mg), optionally coated with a galvanic treatment.

  • the insulating coating 6 may be of plastic over-pressed on the signal conductor 5.
  • Coating 6 exhibits special material lightenings 16 for imparting the desired impedance to the transmission line 4.

  • at least one of the second half shells 11, 12 of coating 6 comprises a projection 26 protruding from the half shell itself towards the tubular structure 18 so as to influence in closing, and thus in compression, at least one portion of the tubular structure 18, preferably at abutment 20, that is, at the portion wherein the tubular structure 18 fits on the signal conductor 5.
  • each of said second half shells 11, 12 comprises, opposite to the tubular structure 18, a pin 32, preferably arranged at projection 26, but opposite thereto, so as to be influenced by the first half shells 9, 10 in a closed configuration of the same.
  • a pin 32 preferably arranged at projection 26, but opposite thereto, so as to be influenced by the first half shells 9, 10 in a closed configuration of the same.
  • the tubular structure 18 is blocked in compression inside seat 28.
  • the central element of the coaxial cable 4' is connected to the tubular structure 18 and to the signal conductor 5 with the interposition of a condenser 36.
  • Condenser 36 insulates the transmission line 4 from low frequency electrical phenomena that generate in the outer environment.
  • Condenser 36 could for example be of the cylindrical or parallelepipedal type.
  • a first end 38 of condenser 36 engages on a fork 40 obtained on the first end portion 5' of conductor 5, so as to form a shape coupling therewith.
  • a peg 42 of conductor material is interposed between the tubular structure 18 and condenser 36, suitable both for forming an electrical connection between condenser 36 and the tubular structure 18, and for influencing condenser 36 in abutment against said fork 40.
  • said peg 42 is made integral with the tubular structure, for example as a tab integrally protruding from the body of the tubular structure 18.
  • half shells 11, 12 comprise a seat 44 obtained inside said semi impressions 13, 14.
  • Seat 44 advantageously seats condenser 36 so as to block the same into electrical contact position with the conductor element 5.
  • Body 8 exhibits a port 49 for accessing the input terminal 2.
  • Jaws 50, 51 exhibit a triangular section or triangular with circular unions.
  • Port 49 carries a screw 52 exhibiting a threaded stem portion 56 screwable in a counter-threaded seat 57 obtained on body 8, and a stem portion 58 released on the diameter close to the head for moving axially but in a lockable manner within its seat 53.
  • the hinge of port 49 is formed through two aligned cylindrical protuberances 54, 55 made integral into port 49, and inserted into two complementary cylindrical slots obtained in shells 9 and 10 of body 8.

  • a high number of shared components may be used for the different shapes of the output terminal, without changing the basic pattern of body 8.
  • the difference between the various shapes of the output terminal 3 is obtained by sharing the basic structure and providing the signal conductor 5 with just an interchangeable tang that adapts to the shape of the output terminal 3.
  • the connecting element allows using a single connection between an input and an output without the aid of any printed circuit.
  • Such multiple devices typically comprise a printed circuit suitable for managing multiple connections; however, such circuit causes signal noises and increases the production and assembly costs.
  • the element of the present invention on the other hand, it is possible to use an element having a single input and a single output without the interposition of any printed circuit, so as to reduce the overall dimensions and costs while ensuring higher clarity of the transmitted signal.
  • the described connecting element also allows a more regular and rational arrangement of the coaxial cables connected thereto.
  • coaxial cables are typically connected to the input terminal and thus curved opposite to the output terminal. Due to the overall dimensions and to the arrangement of the connecting elements, said coaxial cables must undergo sudden bending right at the input terminal.
  • the signal conductor has a curved shape, for example an ⁇ S' shape, or in any case such as to extend opposite to the input terminal, it is possible to move back the input terminal as much as possible so as to ensure a smoother bending of the coaxial cable.
  • Such more favourable bending prevents the cable cracking, facilitates the coaxial cable assembly and improves the signal transmission.
  • the structure of the containment half shells of the conductor always ensures the electrical continuity between the input terminal and the output terminal.
  • the presence of projections and pins ensures a pressure action that facilitates the blocking and the containment of the conductor element and of the optional condenser.
