Definitions

  • This invention concerns a connection structure, particularly for connections with one or more electrical cables of the coaxial reticular screen type.
  • coaxial electrical cables particularly those meant to carry high-frequency signals, for example. the shielded cables of television aeriels or those adapted to transmit microphone signals. require adequate protection, namely, a correct screening from the electromagnetic waves always present in the cable and the environment, and which often cause disturbance and/or alteration both of the signal and the environment.
  • Protection against the electromagnetic waves in the environment normally consists of a braided wire or mesh, formed of thin copper threads. which completely surrounds the electrical conductor that transports the signal and which is insulated from the conductor by an insulating sheath. placed concentrically around the conductor. Another insulating sheath is then placed around the mesh itself.
  • the purpose of the reticular mesh is to allow the central conductor to transfer the signal running along it without dispersion towards the exterior. whilst at the same time not being affected by the outward environment.
  • This invention aims to create a connecting structure for sockets, plugs and similar devices where a connection of one or more coaxial screened cables is required, while strictly respecting the regular coaxial nature of the screen relative to the central conductor and with long-term efficacy and stability.
  • a further aim is the creation of a connecting structure similar to the above, which will be structurally simple, easy to assemble and competitively priced with regard to those currently available.
  • Fig. 1 illustrates a coaxial cable C, made in the way described, by a central single-wire conductor C1, surrounded by an intermediary insulating sheath C2, around which there is wound a braided wire or reticular mesh shield C3, externally surrounded and protected by the external insulating sheath C4.
  • a plug 1 for connecting at least one coaxial cable C comprises a main body 2 with two cavities 3 and 4 placed at right angles.
  • a cavity 3 is placed so as to allow the insertion of a structure 5 in electro-insulating carrier material, held internally, a copper strip 6 equipped with an elasticated aperture 8, intended to receive and hold the copper single wire C1 of the coaxial cable C.
  • Structure 5 is pierced with holes that will accommodate the standing pins 7B and 7D of a metallic base 7 from which emerges a tubular cylinder 7C, set so as to receive the contact of the external tubular zone of a plug's earth. or viceversa.
  • the function of the pins 7B and 7D is to distance the metallic base 7 from the parallel base of the structure 5, where there are circuit tracks (not represented) with possible condensers and seams ensuring the correct passage of the two currents. which are, respectively, useful and harmful. or shielding. Consequently, the latter are prevented from causing impedances in the useful circuitry.
  • the two parts 5 and 7 are fastened together by the beading 7A.
  • Numbers 10 and 11 indicate the soft soldering used to join the copper strip 6 and a pin 12 to the common circuitry.
  • the other cavity 4 of the body 2 is furnished with a bottom 13 from which protrudes a truncated cone 14 with an axial hole 15, and terminating in a sharp edge 16.
  • the hole 15 has the same standardized diameter as the intermediary insulating sheath C2 of the coaxial cable C, in such a way that the circular sharp edge skims the external surface of the said insulating sheath and slips between this and the conducting braided wire or mesh C3, which, in this way, is forced to widen and rest against the external surface of the truncated cone 14.
  • a clamping carriage or block 20 is slipped over the external sheath C4 of the cable C, having a hole with a diameter slightly greater than the external sheath C4.
  • the base of the said hole terminates in a conical cavity with an inclination equal to that of the truncated cone 14, so that the sliding of the block or carriage 20 within the cavity 4 causes the end 21 of the external sheath C4 to be crushed centripetally against the external surface of the truncated cone 14, with the electro-conducting mesh or braided wire in-between.
  • the latter will, therefore, be correctly positioned in close contact with the cone 14.
  • the sliding of the block or carriage will be forced and regulated by at least one screw device.
  • the shape of a screw with that purpose is represented by the broken lines and indicated by the number 22.
  • the number 23 indicates a central hole in the main body 2, in which the screw 22 will be used. Screwing it onto a lead screw of the block 20 will determine the nature of the sliding, by pressing the electro-conducting mesh or braided wire C3 against the truncated cone 14.
  • the plug which encloses the connecting structure is practically composed of two box-shaped bodies, indicated by the numbers 31 and 32, and by a clamping block or carriage 33.
  • the body 31 has the form of a small quadrangular tray on the bottom 31a of which there is designed a small chute or tube 31b which is intended for inserting into a normal plug for coaxial cables.
  • a metallic pivot-pin, coaxial to the tube 31a, is isolated from body 31 by means of an insulator bush 35.
  • the box-shaped body 31 is then fitted internally with distance spacers 36 (figure 4) for a panel or plate 37, in insulating material, supporting a normal printed circuit 38 for the decodification of in-coming signals and furnished centrally with a hole 37a to allow the end of the pivot-pin 34 to pass.
  • the said pivot-pin is firmly welded to the plate as shown by 37b in figures 7 and 9. Furthermore, this plate will have earth contacts, designed to rest on the corresponding contacts inside the body.
  • Two identical bushes 39-39a are fastened to the plate 37 which carries the printed circuit. Made in insulating material. they have a square or round cross-section and are parallel to one another. crossed axially by a section of metal conductor 40 and40a respectively (figures 4.8 and 9), these being welded to plate 37 and shorter in length than their respective bushes 39 and 39a. in order to create a square countersink 42 and 42a, respectively, at the ends of said bushes.
  • quadrangular or round metal heads, 43 and 43a respectively, in a single body or integral with the ends of the conductors 40,40a, as well as a head in insulating material 44,44a at the end of a screw 45,45a inserted on a lead screw located coaxially in body 32 of the metallic plug.
  • the heads 44,44a in insulating material are essentially truncated pyramids in form with a quadrangular base, as can be clearly seen in figures 8 and 9, and are used to block the central single-wire C1 of the coaxial cable C.
  • a catch 145 operated by a spring 146 -see Fig.10- can be inserted between each screw 45,45a, making it easier to block and unblock the single-wire C1 of cable C.
  • insulator bush 39 is partially cut away for the sole purpose of showing its metal head 43, whilst bush 39a reveals the truncated pyramid end of the countersink 42.
  • the main body 32 of the plug preferably made from die-cast zinc-aluminium-magnesium alloy, like the lid 31, has an appendage in the form of a quadrangular frame 46, of the right size to enclose the metallic lid 31, which holds the plug tube and the printed circuit.
  • the secure clamping of body 31 within the frame of body 32 is obtained by means of flanged pegs 47, integral with body 32 and inserted into the holes 47a placed in the corresponding positions in body 31.
  • body 32 In the upper part of body 32 there are two identical square cavities 48,48a (figure 4), placed so as to receive the parallel insulator bushes 39,39a, and deep enough to take the ends of the above-mentioned blocking heads 43,43a and 44,44a.
  • the block or carriage 33 (figure 1), equipped externally with two pairs of prismatic runners 59, to run within corresponding grooves on the faces of the two sides 53,51 of body 32 (figure 6), and internally with two cylindrical cavities 60.
  • said cavities 60 are cylindrical up to the sharp edge of the said truncated-cone appendages 53,53a, and then they become truncated-cone countersinks 61,61a, able to contain the screening sheath C3 and the external insulating sheath C4 of the coaxial cable pressed between the said surface cones, as already described in relation to Fig.2 in the first version.
  • the stripped central conductor C1 is blocked by gripping it with the screw 45 against the fixed head 43, after which the carriage 33 is pushed completely inside the cavity 49, so enabling its countersunk surface 61 to block the screening sheath securely and concentrically against the truncated-cone appendage.
  • the carriage 33 is securely blocked within the cavity 49 by means of a screw 62 inserted in a hole 63 made in the body 32 of the plug and tightened inside a lead screw 64 suitably located in the carriage 33.
  • this screened connection structure as described and illustrated here, can be modified and varied by structural and functional equivalents, without falling outside the protected limits of this invention.
  • the said appendages 53,53a rather than being perfect truncated cones, could be made in truncated pyramid form with a polygonal base or similar.
  • the insulating materials can be varied according to the use made of the coaxial cables, and the panel or plate which holds the printed circuit may even be omitted.
