Definitions

  • the invention relates to an electrical connection element to be soldered on a conductive layer, itself placed on a glazing (in particular for automotive glazing with electric heating), element provided with a terminal intended for the brazed junction, with a segment of wires braided consisting of a flat and flexible braid and finally a connector placed at the end of the segment of braided threads.
  • the electrical connection elements of this type are widely employees with automobile rear windows with heating, for which the heating resistors are installed, under the forms a baking paste, on the surface of the glass, using a process screen-printed for subsequent baking at bending and tempering of windows.
  • Collector strips, on which the terminal of electrical connection elements is soldered after cooking, are installed at the same time, when laying these heating filaments.
  • the solder lug is made up of a part metallic, the central part of which is bent and welded at the end of the wires braided.
  • the connector located at the free end of the braided wire segment is, meanwhile, a flat connector, to which is applied, when connecting on the power supply system, a complementary flat connector.
  • one end of the segment of braided son which is consisting of a flat braid, is separated in the middle, in the direction of the length, forming the solder terminal, and the two arms thus created are bent in opposite directions and orthogonal to the wire segment.
  • a flat connector in the form a mounting lug is provided, for this model also, to the other end of the braided wire segment.
  • connection element by crimping consists, in time normal, of a curved metal part, whose deformable sections surround the end of the segment of braided wires, this same end of wires then being crimped between these sections.
  • connection elements by crimping are not suitable for connection with a flat braid, if although, until now, only the usual round cables were usable with round contact cards.
  • the electrical connection elements of the type described at the start, with a segment of braided wires in the form of a round cable have, they also have different disadvantages.
  • braids round an effective weld between the cable and the solder terminal cannot be carried out with the necessary manufacturing safety measures. Indeed, the first of all, the round braid must be widened, before or during the welding process. causing an uncontrolled deformation of the wire harness of the cable. These irregularities occasionally cause difficulties when welding with the pod.
  • the soldering robots that are used to braze the elements of electrical connection on the glass sheet just are not suitable for processing electrical connection elements provided with a cable round.
  • connection element electric of the type described above, which is provided with a plug round contact while retaining a segment of braided wires having the shape a flat and flexible braid.
  • the electrical connection element according to the invention is distinguished by that the connector, using the round contact plug, is provided with a fitting and in that a metallic reducer, which is welded or brazed on the end of the braided wires, the front part of which, reduced in width, is connected to the fitting by a narrow tab is placed between the segment of braided threads and this same connection.
  • the connector of the contact plug it is preferable to shape the connector of the contact plug so as to allow a connection by crimping, the connector being crushed by plastic deformation on the narrow tab of the reducer.
  • the flexible segment of braided wires 1 comes from a flat copper braid and may consist of wires covered with tin. It has a rectangular section, with a width of 6 mm and a thickness of 0.8 mm.
  • a rigid brazing lug 3, made of a piece of copper, is fixed, or welded in certain cases, to the end 2 of this segment 1, for example by means of ultrasonic welding.
  • This terminal 3 will preferably be a piece of silvery copper 0.8 mm thick. Its length L can be approximately 25 mm and its width B 4 mm.
  • the central part 4 of the terminal is bent upwards and thus forms a connecting segment, in the form of a bridge, between the two segments 5 of the terminal, the lower surfaces of which are soldered to the conductive layer of the glass.
  • a reduction gear 9 is fixed to the other end 8 of the braided wire segment 1, and this in an appropriate manner, also by means of ultrasonic welding.
  • This reducer 9 can also consist of a piece of copper 0.8 mm thick and be covered with silver. It will preferably have, on the end 8 connected to the segment of braided wires 1, the same width as this segment of wires. Its width will then decrease to the other end and it will form a narrow tongue 10, which can be 2 mm wide.
  • the contact plug 12 is placed inside an insulating tube 13 and connected to a corresponding coupling connector when connected to the vehicle's power supply system. The construction of the plug 12 and of the tube 13, as well as the positioning and the fixing of the plug 12 in this same tube 13 can take radically different forms and are not the object of the invention.
  • connection fitting by crimping 15 consists in the case presented of a thin piece of metal and has two curved sections 16 which are folded one against each other, so as to surround the tongue 10, and are joined by pressing to this tongue 10 by means of an appropriate instrument.
  • the braided wire segment 1 is wrapped, in the known manner by a insulating sheath 18 which is deposited for example by a thermal process on this segment 1.
  • This sheath 18 also covers the reducer 9 and, at least in part, the connection by crimping 15. It thus continues into the tube insulator 13, so that the entire electrical connection element, with the exception of the rigid terminal 3, is completely electrically insulated.
