Definitions

  • the present invention relates to a contact electric tulip type, including a ring of fingers arranged parallel to each other along the generatrices of a cylinder and joined by a common base.
  • It relates more precisely to a type contact tulip, intended to cooperate with a cylindrical male contact and having parallel contact fingers arranged side by side according to the generators of a cylinder and provided a common base, contact including a limiter radial stroke of the fingers consisting of a coaxial tube fingers on which fingers come into position maximum radial expansion.
  • Such fingers are subject to current flow to electrodynamic forces tending to move the fingers radially. If for example due to mechanical forces and significant electrodynamics, the deformation exceeds the elastic limit of the material, the contact is deteriorated because it no longer has the necessary qualities, in particular the elasticity qualities, to ensure current flow with suitable contact resistance.
  • 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 when radial expansion of the fingers.
  • the fingers comprise a rod integral with said base and a stud contact, whose distance from the longitudinal axis of the contact is less than that of the rod, and said tube is arranged 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 as a contact not equipped with radial stroke limiter unlike those of the prior art where the tube or the outer ring increases the size of the contact. Now this can be prohibitive in certain applications, in particularly in the breaking chambers of circuit breakers high or medium voltage. Thanks to this improvement, the gas flow around the contact is not disturbed.
  • said elastic member is a blade with one fixing end fixed near said base and one free end of which is in abutment against fingers in rest position.
  • each pad has a notch internal housing the free ends of the tube and said blade.
  • a base comprising grooves receiving the ends of fixing of the blades, the tube blocking said blades once said base fitted on it and being itself blocked by the fingers, the base of the fingers being fixed on said base.
  • the base supports a tube of interior thermal protection.
  • Figure 1 is a partially sectional view longitudinal of the 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 according to the generators of a cylinder and provided with a base common 3.
  • the fingers 2 comprises a rod 6 integral with said base 3 and a contact pad 7, the distance of which relative to the longitudinal axis 8 of the contact is less to that of the rod 6.
  • the studs 7 are provided with a notch internal 10.
  • the contact also includes a stroke limiter radial fingers consisting of a tube 4 coaxial with the fingers 2.
  • the tube 4 is intended to be disposed internally at the fingers 2, its free end being received in the notches 10 formed 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 of fixing blades 5 of length substantially equal to that of tube 4 and made of a metal with good properties elastic. To this base 11 is also rigidly fixed an inner protection tube 13 made of a metal temperature resistant and provides protection internal thermal of the contact when an electric arc appears inside the tulip contact.
  • 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 assembly is then fitted into the base 3 of the fingers 2, the free ends of the tube 4 and the blades 5 which are housed in the notches 10.
  • base 3 is provided with positioning pins 15, visible on the Figures 2 and 3, coming to fit into the provided holes in the base 11.
  • the base 3 of the fingers 2 is then fixed on the base 11 by means of fixing studs 16 connected to a support part of the contact not shown.
  • fingers 2 When the tulip contact is engaged with a male contact 1, as shown in figure 3, fingers 2 assume a maximum position of radial expansion. 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 due to its elasticity it works in compression, pushing the pad 7 of each finger 2 against the external surface of the male contact 1, this thrust adding to the effort clean of fingers 2.
