Definitions

  • the present invention relates to a heating element and an electrical connector for a heating element comprising means for fixing it to one end of said heating element and for connecting it to a power supply conductor.
  • Such heating elements are used in particular in toasters.
  • These heating elements generally comprise a bar or tube made of electrically insulating material around which a resistive heating wire is helically wound.
  • This resistive heating wire is brought to a very high temperature when supplied with electric current.
  • the object of the present invention is to create a heating element which fulfills the above conditions while being inexpensive to manufacture, compatible with very large series production.
  • this heating element is characterized in that the resistive heating wire comprises at minus one coil end fixed by welding to the connector.
  • the electrical connector 1 for the heating element 2 consists of a cut metal sheet having slots 3, 4, 5, 6, 7 (see Figure 4). This cut sheet is rolled around an axis x-x '(see Figures 1 and 2) intended to correspond to that of the heating element 2.
  • the slots 3, 4, 5, 6, 7, and the tongue 9 extend, before rolling the sheet perpendicular to the axis xx 'around which the cut sheet is then rolled.
  • the tongue-forming part 9 is connected to the part 8 having slots 3, 4, 5, 6, 7 by a tab 10 whose width measured in the direction of the length of the tongue 8 is less than the height of slots 3, 4, 5, 6, 7.
  • the dimensions of the cut sheet are such that when it is rolled around said axis x-x ', the opposite ends of the tongue 9 and the opposite tops of the slots 3, 4, 5, 6, 7 are almost in contact (see Figures 1 and 3).
  • the sheet from which the connector according to the invention is made is preferably made of metal or alloy which is a good conductor of heat and electricity and has a certain elasticity such as brass.
  • Figures 1 and 5 show that the connector 1 is associated with an electrical power supply conductor constituted by a cut metal blade 11 of the same kind as the connector 1.
  • This blade 11 has two cut tabs 12, 13, folded and bent towards each other so as to define therebetween a substantially cylindrical surface 14a (see FIG. 5) adapted to that defined by the rolled part 8 having the slots of the connector 1.
  • the part 11a of the blade 11 adjacent to the two tongues 12, 13 has a curvature, the convexity is directed opposite the tongues 12, 13, and which substantially follows the curvature of these tongues 12, 13.
  • the connector 1 is fixed to one of the ends 2a of a heating element 2 comprising a tube 14 of electrically insulating material such as soapstone, around which a resistive heating wire 15 is helically wound.
  • a cap 16 made of insulating material is fixed around the part 9 forming a tongue and the part with tight turns 15a of the resistive wire and partly around the part 8 having slots.
  • This circulation of air provides cooling of the assembly of the connector 1, so that there is no risk of it becoming excessively hot due to its direct contact with the heating wire 15.
  • the thermal expansions and contractions undergone by the connector 1 following a multitude of heating and cooling cycles are not likely to affect the mechanical properties of the connector so that a perfect connection mechanical and an excellent electrical connection between the connector 1 and the heating wire 15 are maintained for a very long service life.
  • the manufacture of the connector 1 is extremely simple since it is carried out by simple cutting and rolling of a metal sheet which are easily automated.
  • the mounting of the connector 1 on the heating element 2 is also simple and automated, since it simply consists of an interlocking along the axis x-x '.
  • the part 8 of the connector may not be rolled, and remain flat, such as after cutting.
  • the tongues 12 and 13, instead of being shaped like a lyre, are then shaped like jaws, the connector engaging between them according to the knife switch system.
