Definitions

  • the present invention relates to an electrical contact of the tulip type, comprising a crown of fingers arranged parallel to each other according to the generatrices of a cylinder and joined by a common base.
  • a type contact tulip intended to cooperate with a cylindrical male contact and having parallel contact fingers arranged side by side along the generators of a cylinder and provided with a common base, contact comprising a radial finger stroke limiter constituted a coaxial tube with fingers on which abut fingers in maximum radial expansion position.
  • Such contact according to the preamble of claim 1 is described for example in FR-A-2 492 579.
  • Such fingers are subject to current flow to electrodynamic forces tending to displace fingers radially. If for example due to efforts important mechanical and electrodynamic, the deformation exceeds the elastic limit of the material, the contact is deteriorated because it no longer has the qualities necessary, in particular the qualities of elasticity, for ensure current flow with a resistance of suitable contact.
  • the invention solves this problem by proposing a particularly simple mounting arrangement which increases the contact force in the expansion position.
  • each time finger is associated with an elastic member disposed between said tube and finger and working in compression during expansion radial fingers and said tube is placed inside the fingers and in position expansion, the fingers abut against the tube by through a surface formed in the studs finger contacts.
  • the contact according to the invention has the same dimensions that a contact not fitted with a travel limiter radial unlike those of the prior art where the outer tube or ring increases overall dimensions of the contact.
  • this can be prohibitive in some applications, especially in switching chambers high or medium voltage circuit breakers. grace at this improvement the flow of gas around contact is not disturbed.
  • said elastic member is a blade with one fixing end attached close of said base and of which a free end is in abutment against fingers in rest position.
  • each pad has a notch internal in which the free ends are housed of the tube and said blade.
  • a base comprising grooves receiving the ends for fixing the blades, the tube blocking said blades blades once said pedestal fitted thereon and being itself blocked by the fingers, the base of the fingers being fixed on said base.
  • the base supports a tube interior thermal protection.
  • Figure 1 is a view partially in longitudinal section component parts of a conforming contact to the invention.
  • Figure 2 is a longitudinal sectional view of a contact according to the invention at rest.
  • Figure 3 is a longitudinal sectional view of a contact according to the invention in expansion position maximum radial.
  • the type contact tulip comprises conventionally parallel contact fingers 2, arranged side by side side by side on the generators of a cylinder and provided of a common base 3.
  • the fingers 2 has a rod 6 secured to said base 3 and a contact pad 7, the distance from the longitudinal axis 8 of the contact is less than that of the rod 6.
  • the studs 7 are provided with an internal notch 10.
  • the contact also includes a stroke limiter radial fingers consisting of a tube 4 coaxial with fingers 2.
  • the tube 4 is intended to be arranged internally at fingers 2, its free end coming to be housed in the notches 10 made in the studs 7.
  • the contact finally comprises a tubular base 11 having grooves 12 arranged on its periphery and regularly distributed in correspondence available fingers 2. These grooves 12 receive the ends for fixing blades 5 of substantially length equal to that of tube 4 and made of a metal with good elastic properties. At this base 11 is also rigidly fixed an inner protection tube 13 made of temperature resistant metal and ensuring internal thermal protection of the contact when an electric arc appears inside the contact tulip.
  • the tube 4 blocks the blades 5 with an internal flange 14 keeping the ends of the blades 5 in the grooves 12, once said base 11 fitted into the tube 4.
  • This together is then fitted into the base 3 of the fingers 2, the free ends of the tube 4 and of the blades 5 coming from fit into the notches 10.
  • the base 3 is provided with positioning pins 15, visible in Figures 2 and 3, coming to fit in orifices provided in the base 11.
  • the base 3 of the fingers 2 is then fixed on the base 11 via of fixing studs 16 connected to a support part of the contact not shown.
  • the fingers 2 When the tulip contact is engaged with a male contact 1, as shown in figure 3, the fingers 2 take a maximum expansion position radial. This expansion is limited by the stop of the fingers 2 against the rigid tube 4 by their surface 9. Between this tube 4 and the surface 9 is the free end of a blade 5 for each finger 2. This blade 5 is therefore deformed and because of its elasticity it works in compression, pushing the pad 7 of each finger 2 against the external surface of male contact 1, this thrust adding up at the finger effort 2.
