Definitions

  • the invention relates to a laser-marking electric cable.
  • German patent No. 3147230 discloses a cable whose outer surface first receives by spraying a color coating which is cured by RF waves or infrared before being burned by laser radiation .
  • this document is concerned only with the surface burning obtained by laser radiation.
  • a US patent 4,370,542 claims the marking of a cable by laser, but it in fact only relates to the relative positioning of this cable and of the laser source.
  • Against by the present invention relates to a particular arrangement of the outer layer of an electric cable allowing marking by laser beam.
  • an electric cable markable by laser comprising an outer layer allowing the realization of such a marking, characterized in that this outer layer is of contrasting color compared to the color of an absorbent undercoat at the wavelength of the laser beam, this outer layer being a thin layer which, during marking, is destroyed throughout its thickness by the laser beam so as to allow the sublayer to appear.
  • the invention provides an electrical cable in which the outer layer is light in color and the sublayer in dark color, and in which the outer layer has a thickness of between 5 and 50 micrometers.
  • FIG. 1 illustrates the marking by laser beam according to the invention.
  • a ray 10 from a laser source 11 is directed towards the surface of an electrical cable 12.
  • This cable comprises a thin outer layer 13, for example between 5 and 50 micrometers, which surrounds an underlayer 14. This layer exterior is destroyed throughout its thickness at the point of impact 15 of the laser beam thereon, thus revealing the sub-layer 14 which absorbs said laser beam.
  • This outer layer 13 being of a contrasting color, for example clear, with respect to the sub-layer, for example dark, the invention makes it possible to obtain a quality marking.
  • This sublayer 14 can be pigmented in dark brown or black so as to promote the absorption of the laser beam and allow contrast with the outer layer 13.
  • the pigments used can be dark brown pigments "Brown Sicopal K 2795" from the company BASF or black pigments "FA 2306" from the company FERRO, or a combination of pigments, for example based on the two pigments mentioned.
  • the minimum thickness of such a sub-layer 14 is such that it makes it possible to stop the penetration of the laser beam 10.
  • this radial thickness is of the order of 25 micrometers.
  • this thickness is of the order of 15 micrometers.
  • the pigment concentration must be between 5 and 15% with the first type of undercoat and between 30 and 35% with the second type of undercoat, so as to preserve good mechanical strength of this undercoat. -layer and to obtain sufficient coloring.
  • the outer layer 13 must be such that it allows just the necessary absorption of the laser beam to cause its own pyrolysis. It must indeed be the least absorbent possible while remaining burnable by the laser beam.
  • PTFE polytetrafluoroethylene
  • BAYER a product of the company BAYER composed of "Desmophen F951" which is a polyol and "Desmodur CT” which is a polyisocyanate, in solution for example in a mixture of cresol and xylene.
  • the pigmentation of this layer 13 can be obtained using a white pigment of titanium dioxide in all its forms, rutile or anatase for example, such as "Kronos RN59" from the company NL Chemicals.
  • This white pigment can be used alone or mixed with colored pigments in small quantities to obtain clear or pastel shades.
  • the thickness of such a layer has a maximum value depending on the type of laser used and its emission power. Indeed, this laser must be able to volatilize this layer to reveal the dark underlay 14.
  • the thickness of this layer must preferably be between 5 and 20 micrometers with an outer layer 13 of the first type. considered, and between 5 and 25 micrometers with an outer layer 13 of the second type considered.
  • This sublayer is then pigmented in the same way as sublayer 14, so that all of the polyimide and polyamide sublayer has a minimum thickness of the order of 15 micrometers.
  • varnishes used are baked according to the traditional processes used in the enameled wire industry, for example by multi-pass coating with dynamic baking in the "parade” oven obtained by the process known as "in die”, or the process known as “dipping” ".
  • varnish deposition techniques such as for example electrophoresis, electrostatic powdering and / or in a fluidized bath.
  • the laser marking according to the invention can be carried out on a machine of the type described in US Pat. No. 4,370,542 which allows relative positioning of a cable and a laser source.
  • Such a marking can also be carried out by moving a mask in front of a wide laser beam, for example obtained from a CO2 laser (“mask” method), the laser beam being focused after having passed through said mask.
  • a wide laser beam for example obtained from a CO2 laser (“mask” method
  • FIGS. 2 and 3 represent two examples of embodiment of such cables which can be marked by laser according to the invention.
  • the cable illustrated in Figure 2 consists of: - a central conductor 16 made of copper, or copper alloy, or aluminum, or aluminum alloy, protected or not by a coating metallic (tin, nickel, silver, etc ...) - a three-layer insulation comprising: . two taped layers 17 and 18 made of polyimide back-coated with adhesive or thermosetting, joined together by heat treatment ("Kapfon F", “Kapfon HFE” trademarks of Du Pont de Nemours, "Upilex F” trademark by UBE Industriels, "Apica AF” trademark registered by KANEGAFUCHI). . a third external layer consisting of all 3 varnishes 20, 21, 19 deposited successively: layer 20 in black polyimide, layer 21 in black aromatic polyamide, layer 19 in white polyurethane; these 3 varnishes have a service temperature above 150 ° C.
  • the cable illustrated in Figure 3 consists of: - a central conductor 16; - a three-layer insulation comprising: . a first ribbon layer 17 made of polyimide as described in the previous example. . a second tape or extruded layer 22, made of thermoplastic material with a melting temperature greater than or equal to 150 ° C., joined together by heat treatment: polytetrafluoroethylene ("Teflon PTFE", registered trademark of Du Pont de Nemours), perfluoroalkoxy - polytetrafluoroethylene (“Teflon PFA ", registered trademark Du Pont de Nemours," Hostaflon TFA “registered trademark Hoechst), polytetrafluoprethylene-propylene (“ Teflon FEP “, registered trademark Du Pont de Nemours), polyethylene-tetrafluoroethylene (“ Tefzel “, registered trademark Du Pont de Nemours) , polyvinylidene fluoride ("Kynar”, trademark Pennwalt), poly
  • the marking according to the invention can also be applied to constructions of electric cables, in particular for aerospace use, with improved electrical characteristics, described in French Patent No. 2,555,799.
  • the cable according to the invention therefore allows marking which consists in burning a thin external layer, existing or added for the occasion, the gaps thus created in this layer revealing the underlying insulation. This must satisfy the electrical, mechanical, etc. clauses imposed on the cable, and in addition must be able to resist laser radiation, the power of which is adjusted to the level just necessary to burn the outer thin layer.
