Definitions

  • the present invention relates to electrical interrupting, switching, reversing and similar devices comprising pressure contact devices actuated by a rotating member such as a cam or the like.
  • the invention aims to improve this type of device and make its operation safer.
  • the offset means are constituted by an auxiliary cam, co-axial with the main cam and angularly integral with the latter, this auxiliary cam acting on a carriage guided perpendicularly to the opening and closing stroke of the movable contact and which, when the latter is in its closed position, moves it positively with respect to the fixed contact.
  • the element represented in fig. 1 and 2 comprises a lower plate 1 made of molded material integral with two opposite projections 1a on which a flat cover 2 rests, this plate and this cover being crossed by a control pin 3 provided square in the example shown, but which could have grooves, grooves or other equivalent conformation.
  • a main cam 4 capable of acting on radial pushers 5, which in turn actuate double movable contacts 6 to move them away from fixed contacts 7 against which they are applied by springs 8 bearing on the projections 1a.
  • each pusher 5 is secured to a U-shaped guide body 10 (see fig. 3) whose branches slide in appropriate grooves 1b and 2a (fig. 2) of the upper face of the plate 1 and from that of the lower cover 2.
  • the bottom of this U carries a stud 11 (fig. 3) which passes through an elongated slot 12a punched in the central part of the conductive strip 12 carrying the two movable contacts 6 associated with the pusher considered.
  • the spring 8 is housed between the two branches of the aforementioned U and it acts on the bar 12. It is important to note that the latter is not straight, but that its middle part which includes the slot 12a is offset in the direction of the axis 3 with respect to its two ends fitted with the contacts 6. This results in a profile similar to that of a U, the major part of the branches of which would have been folded down horizontally towards the outside.
  • the fixed contacts 7 are integral with terminals 13 suitably fixed to the bottom of the bowl 1.
  • the axis 3 carries above the main cam 4 an auxiliary cam 14 which, as shown in FIG. 1 comprises four lobes 14a oriented at 45 ° in one direction or the other with respect to the radial axis of said cam 4. These lobes act in passing on an internal boss 15a provided on the edge of a window 15b cut in the central part of a flat carriage 15 slides to slide between the main cam 4 and the cover 2.
  • This carriage 15 has arms 15c oriented parallel to the diameter defined by the assembly rods 9 and which come to enclose with a small clearance the projections 1 c of the plate 1 intended to surround these rods. It is thus guided parallel to the diametrical axis defined by the rods.
  • the window 15b is elongated in this same direction to allow the carriage to move and the boss 15a is located on said diametrical axis.
  • One of the projections 1c is hollowed out with a depression 1d against the bottom of which bears a spring 16 which pushes the carriage 15 in the direction of the diametrically opposite projection.
  • the carriage 15 also has fingers 15d which come to enclose with play the remote middle portion of each of the strips 12 when the corresponding fixed contacts are in the closed position (case of the strip 12 on the right in FIG. 1).
  • the element could comprise two main cams such as 4, respectively arranged against the plate 1 and against the cover 2, the auxiliary cam 14 being mounted between them.
  • one of the pushers 5 would be offset by 180 ° around the axis of its stud 11 so q ⁇ . e its head is brought closer to the cover 2 and not to the plate 1, and can therefore cooperate selectively with the second main cam or upper cam. If the two main cams were then offset by 90 ° and each had two noses, the element would have four useful positions.
  • One could provide for the auxiliary cam 14 eight lobes 14a oriented at 22.5 ° relative to the common axis of the pushers to ensure self-cleaning during the contact closure period.
  • the auxiliary cam could have only two lobes. It is also understood that it would be possible to multiply the variants with more than two pushers oriented in any desired manner with respect to each other.
