Definitions

  • the present invention relates to an electrical contact of the tulip type, comprising a ring of fingers arranged parallel to each other along the generatrices of a cylinder and joined by a common base.
  • a tulip-type contact intended to cooperate with a cylindrical male contact and comprising parallel contact fingers, arranged side by side along the generatrices of a cylinder and provided with a common base, contact comprising a radial stroke of the fingers consisting of a tube coaxial with the fingers on which the fingers abut in the maximum position of radial expansion.
  • Such fingers are subjected during the flow of current to electrodynamic forces tending to move the fingers radially. If, for example due to significant mechanical and electrodynamic forces, the deformation exceeds the elastic limit of the material, the contact is deteriorated because it no longer has the necessary qualities, in particular the qualities of elasticity, to ensure the passage of the current 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 finger is associated with an elastic member disposed between said tube and finger and working in compression during the radial expansion of the fingers.
  • the fingers comprise a rod integral with said base and a contact pad, the distance from the longitudinal axis of the contact is less than that of the rod, and said tube is disposed internally to the fingers and in the expansion position, the fingers abut against the tube via a surface formed in the contact pads of the fingers.
  • the contact according to the invention has the same dimensions as a contact not equipped with a radial stroke limiter, unlike those of the prior art where the outer tube or ring increases the size of the contact.
  • this can be prohibitive in certain applications, in particular in the breaking chambers of high or medium voltage circuit breakers. Thanks to this improvement, the flow of gas around the contact is not disturbed.
  • said elastic member is a blade, one fixing end of which is fixed near said base and one free end of which is in abutment against the fingers in the rest position.
  • each stud has an internal notch in which the free ends of the tube and of said blade are housed.
  • a base comprising grooves receiving the fixing ends of the blades, the tube coming to block said blades once said base fitted onto it and being itself blocked by the fingers, the base of the fingers being fixed on said base.
  • the base supports an internal thermal protection tube.
  • Figure 1 is a partially longitudinal sectional view of the component parts of a contact according 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 the position of maximum radial expansion.
  • the tulip-type contact conventionally comprises parallel contact fingers 2, arranged side by side along the generatrices of a cylinder and provided with a common base 3.
  • the fingers 2 comprises a rod 6 integral with 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 pads 7 are provided with an internal notch 10 .
  • the contact also comprises a radial stroke limiter of the fingers consisting of a tube 4 coaxial with the fingers 2.
  • the tube 4 is intended to be disposed internally with 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 comprising grooves 12 arranged on its periphery and regularly distributed in correspondence at the disposal of the fingers 2. These grooves 12 receive the blade attachment ends 5 of length substantially equal to that of the tube 4 and produced in a metal with good elastic properties.
  • an inner protection tube 13 made of a metal resistant to temperature and ensuring the internal thermal protection of the contact when an electric arc appears inside the tulip contact.
  • the tube 4 comes to block the blades 5 by an internal flange 14 holding the ends of the blades 5 in the grooves 12, once said base 11 is 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 of the blades 5 which are received in the notches 10.
  • the base 3 is provided of positioning pins 15, visible in FIGS. 2 and 3, which fit into holes provided 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.
  • the fingers 2 When the tulip contact is engaged with a male contact 1, as shown in FIG. 3, the 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 because of its elasticity it works in compression, pushing the stud 7 of each finger 2 against the external surface of the male contact 1, this push adding to the force exerted by the fingers 2.
