Definitions

  • the present invention relates to a device to connect electrically with the mains, the ends of a resistive track screen printed on a support.
  • the support on which the track is screen printed resistive can constitute the heating bottom of a heating container such as an electric kettle.
  • connection electric between the ends of the resistive track and the sector is usually carried out by grains of contact carried by an elastic blade bearing on a conductive pad provided at the end of the track resistive.
  • the aforementioned contact grains have a spherical surface, so that contact with the beach driver is punctual.
  • the object of the present invention is to remedy to this disadvantage.
  • the device for electrically connect with the mains, the ends a resistive screen-printed track on an east support characterized in that it includes a stirrup made of electrically insulating in elastic support on two pads of conductive material each having a face plane resting respectively on one end of the resistive track, the two pads each being connected to a free conductive tab relative to stirrup.
  • each of the two tabs extends in an opening in the stirrup, extending substantially perpendicular to the support, this opening with a larger section than that of the tongue.
  • This arrangement facilitates the mounting of caliper and tabs, and prevents the caliper from exerting mechanical stress on the tabs.
  • the stirrup includes in the middle an engaged opening on a threaded rod fixed to the support, a nut being screwed onto this threaded rod and a spring being disposed between the nut and a bearing surface of the caliper.
  • the device for electrically connecting with the sector the ends 1a, 1b of a track resistive 1 screen printed on a support 2 includes a stirrup 3 in electrically insulating material in support elastic on two pads 4a, 4b, of conductive material such as silver, each with a flat side bearing respectively on one of the ends 1a, 1b of the resistive track 1.
  • the two pads 4a, 4b are each connected to a free conductive tab 5a, 5b relative to stirrup 3.
  • Each of the two tabs 5a, 5b extends in an opening 6a, 6b made in the stirrup 3, extending substantially perpendicular to the support 2.
  • openings 6a, 6b have a more section larger than that of the tabs 5a, 5b.
  • stirrup 3 comprises in the middle an opening 7 engaged with play on a threaded rod 8 fixed to support 2.
  • a nut 9 is screwed onto this rod threaded 8 and a spring 10 is disposed between the nut 9 and a support surface of the stirrup 3.
  • the spring 10 is a elastic washer engaged on the threaded rod 8, of which the periphery 10a is supported on an annular surface 11 produced in a recess 12 formed in the stirrup 3.
  • the two studs 4a, 4b each have an enlarged portion 13 supported by a flat surface on a silvery beach of the tip la, 1b of the resistive track 1, and a narrowed part 14 having a rounded end 15 in contact with a cavity of complementary shape made in the surface 3a of the bracket 3 adjacent to the support 2.
  • each tab 5a, 5b includes one end 16 bent at right angles and having a opening engaged on the narrowed part 14 of the stud 4a, 4b corresponding.
  • This narrowed part 14 is crimped on the folded end 16 of the tongue Sa, 5b.
  • the support 2 is in metal such as steel and the threaded rod 8 is welded at support 2.
  • the track resistive 1 is electrically isolated from metal by a dielectric enamel layer.
  • the support 2 can also be made of a material electrically insulating such as alumina.
  • This elastic tightening has the effect of maintaining the flat surface of the pads 4a, 4b flat on the conductive pads formed at the ends 1a, 1b of the resistive track 1.
  • the support 2 carrying the resistive track 1 can constitute for example the heating bottom of a electric kettle or any other heating container.
