Definitions

  • the present invention relates to the field of cables electrical cables, and in particular electrical cables with conductive core flexible.
  • the invention also relates to high transformers voltage which are fitted with high voltage electrical cables for par example electrically supply electrical components to inside an electronic device, such as a TV.
  • the object of the present invention is to propose a solution simple and effective to stiffen the flexible conductive core of electric cables to be used in particular in high voltage transformers fitted with conductive pads of connection.
  • the invention also relates to a manufacturing process a rigid connector for electric cable with flexible conductive core.
  • the invention further relates to an electric cable with a core flexible with at least one end rigidified in a way particular.
  • the invention also relates to a high transformer tension fitted with flexible electrical cables, one end of the core is stiffened so as to allow its easy insertion into the conductive transformer connection pads.
  • the method of manufacturing a connector associated with a cable electric with flexible conductive core consists of strip one end of the cable by removing the plastic sheath protection around the flexible conductive core, to be fixed at the end stripped of the cable in axial abutment against the sheath, a metal disc which has a diameter less than or equal to the diameter of the sheath and which is provided with a central hole through which the flexible conductive core passes, and stiffen the flexible conductive core by a conductive weld which makes also the soul attached to the metal disc.
  • an electrical cable with a core flexible conductor surrounded by an insulating plastic sheath.
  • the cable has a stripped end by removing the sheath around the core, a metal disc with a diameter less than or equal to diameter of the sheath and which is provided with a central hole through which the cable core, the disc being in axial abutment against the sheath.
  • a deposit of conductive solder on the stripped core stiffens the core while mechanically joining the metal disc.
  • the disc has pins on the surface oriented towards the sheath and which sink into the sheath to ensure the at least temporary maintenance of the disc on the cable.
  • the pins can be obtained by stamping the disc and can be regularly distributed on a circle concentric with the central hole of the disc.
  • the central hole is delimited by a frustoconical neck which ensures the centering of the disc around the core and strengthens the cohesion mechanical assembly once covered with solder.
  • a high voltage transformer comprising a winding enclosed in an insulating housing, pellets flexible conductive in which the conductors of output of the winding, and flexible high voltage cables whose stripped ends are stiffened as shown above to be easily inserted into the conductive pads.
  • Figure 1 shows a high voltage transformer of the type described in European Patent No. 0 236 642 with high cables tension with flexible core.
  • Transformer 1 can be used for power the cathode ray tube of a television and has a circuit magnetic 2, a winding 3 with several windings, and pins 4 of electrical connection between the winding 3 and another component electric not shown.
  • Winding 3 has two high outputs voltage, one of which supplies, via a potentiometric block not shown the grids of the cathode ray tube not shown, and the other of which feeds the anode of the cathode ray tube.
  • High voltage flexible cables 5 and 6 supply high voltages from the two outputs of the winding 3.
  • Winding 3 has a protective resin casing which has two safety chimneys 7, 8 intended to receive the stiffened stripped ends 5a and 6a of cables 5 and 6 respectively (the stiffening of the stripped ends is described below).
  • the height of the chimneys 7, 8 is determined according to the corresponding high output voltage.
  • Each chimney 7, 8 has internally at its base, a flexible silicone pad 9 charged with conductive powder allowing the electrical connection between an outlet high voltage 10 of the winding 3 and the stiffened end 5a of the cable 5 corresponding.
  • the electrical connection between outlet 10 and the end stripped 5a of the cable 5 is made by driving the end 5a and the output conductor 10 in the conductive pad 9.
  • bleeder in the underside of the patch conductor 9 is also inserted the end of a conductor 11 from a load resistor 12 called "bleeder". It is the same for the conductive patch not shown linked to the chimney 8.
  • the flexible cable 20 includes a flexible conductive core 21 stranded stranded wire and an insulating sheath 22 of flexible plastic material coaxially surrounding the flexible conductive core 21.
  • One end of the cable 20 is stripped by removing sheath 22 around the core flexible conductive 21.
  • a flat metal disc 23 of small thickness has a diameter less than or equal to the diameter of the sheath 22 and a central hole 24 delimited by a frustoconical neck 25, as well as several pins 26 obtained by stamping the disc 23.
  • the pins 26 are of preferably evenly distributed over a concentric circular path at central hole 24 and directed perpendicular to the plane of the disc in a direction opposite the frustoconical neck 25.
  • the flexible conductive core 21 of the cable 20 is threaded axially in the central hole 24.
  • the disc 23 with its pins 26 directed axially approaches the sheath 22 of the cable 20.
  • the pins 26 then sink axially into the sheath 22 until the disc 23 either in axial abutment against the sheath 22 (the distance separating the sheath 22 and the disc 23 in FIG. 2b is artificially drawn to better distinguish these two elements).
  • the insertion of the pins in the sheath 22 allows good fixing of the disc 23 on the cable 20, the neck frustoconical 25 allowing the disc 23 to be centered around the core flexible conductor 21.
  • a conductive solder is then deposited, for example at using solder-lead alloy on the core flexible conductive 21.
  • Welding in the hot liquid state seeps through capillarity in the available spaces of the multi-stranded strand constituting the flexible conductive core and covers the frustoconical neck 25, so that at cooling of the weld, on the one hand, one end is obtained conductive 27 rigidified cable 20 from the flexible conductive core 21 and on the other hand a welding making the metal disc 23 integral and the conductive end 27.
  • the connector thus obtained in the form of a T is very resistant to buckling, which improves the mechanical characteristics of the removable insertion of the cable 20 into the conductive pad 9.
  • the device of the invention makes it possible, in a simple manner, to make flexible electrical cables usable in circumstances where a priori they do not lend themselves to it, in particular for cases where the flexibility of the conductive core is disabling to ensure the electrical connection.
