Definitions

  • the present invention relates to a device for blocking the bimetal adjustment screw of a thermal disjunction mechanism mounted in a housing of an electrical protection device.
  • the locking of the bimetal adjustment screw is usually ensured by resin or varnish which is introduced, using a metering device, into the hole of the housing containing the adjustment screw so that the resin or the varnish reaches the overlap of the threads of the screw and of the tapped element and this in sufficient quantity to ensure blocking definitively. This process does not however have very high reliability.
  • drying time is more or less long and, throughout it, a constant immobility is required, which complicates the operation.
  • the object of the present invention is to remedy these drawbacks by proposing a device for blocking the bimetal adjusting screw which allows instant, secure and final locking of the adjusting screw, once the adjustment has been made.
  • Another object of the invention is to provide a device which is easy to implement and inexpensive.
  • the present invention relates to a device for blocking the bimetal adjustment screw of a thermal cut-off mechanism mounted in a housing of an electrical protection device, mechanism in which the adjustment screw is accessible from the outside. by a hole in the housing in which the screw can be turned in one direction or the other with respect to a stationary complementary tapped element, in which the screw is engaged, a mechanism in which the adjustment is condemned by blocking the adjustment screw, device characterized in that it comprises a clip arranged so as to come to rest in the hole in the housing and to prevent any movement of the adjusting screw.
  • the clip according to the invention comprises means for tightening the screw and, in particular, the clip is tightened against the screw by the ramp effect on the walls of the hole in the housing.
  • the clip has a contact surface for the screw, having a succession of reliefs and grooves whose pitch is substantially identical to that of the thread of the screw. This arrangement optimizes tightening.
  • the clip may have means for snapping into the hole in the housing, to prevent its removal.
  • the clip and the hole in the housing preferably have complementary means for blocking the shape of the clip.
  • the clip has a substantially "U” shape and the branches of the "U” have a rectangular section.
  • the branches of the clip may comprise, turned outwards, snap stops intended to cooperate with reliefs of the hole to prevent the clip from being removed.
  • the free end of the branches of the clip preferably comprises a chamfer intended to cooperate with the relief of the hole to ensure the tightening of the screw by ramp effect.
  • FIG. 1 shows a perspective view of a clip 1 according to the invention.
  • the clip 1 comprises a parallelepiped base 2 from which extend two branches 3 symmetrical and parallel to each other, leaving two lateral zones 4 and a central zone 5 on the face, of the parallelepiped base 2, which carries them.
  • the branches 3 comprise, at a distance from the parallelepiped base 2, a projecting or abutment part 6 provided with a face 7 parallel to and opposite the corresponding lateral zone 4 and with an inclined face 8 turned substantially opposite to said lateral zone 4.
  • the projecting parts 6 extend over the entire width of the branches 3, the parallel faces 7 having a surface less than that of the lateral zones 4.
  • the branches 3 then have a section 9 provided with a succession of reliefs and grooves, the sections 9 of the two branches 3 being opposite one another.
  • the pitch of this succession of reliefs and grooves is substantially identical to that of the thread of the adjusting screw 10 (see Figures 2 and 3).
  • the branches have, at their free end 11, a chamfer 12 which forms an obtuse angle with the external face of said branch.
  • FIGS 2 and 3 are partial views of the housing of an electrical protection device provided with the locking device according to the invention.
  • the hole in the housing 13 is delimited by two flat walls 14 which are parallel to the bottom 15 of the housing 13 and by two walls 16 which are symmetrical and perpendicular to the faces 14 and have reliefs.
  • the walls 14, 16 extend from the mouth 17 of the hole towards a housing 18 which receives, immobile in rotation and in translation, a nut 19 in which is housed the adjusting screw 10 intended for adjusting the bimetallic strip of the thermal disjunction mechanism.
  • the mouth 17 has the shape of a parallelepiped whose long sides are oriented parallel to the bottom 15 of the housing.
  • the walls 16 then comprise a relief 20 provided, on the side of the mouth 17, with a chamfer 21.
  • the relief 20 is extended by a reinforcement 22 which is provided, opposite said relief 20, with a chamfer 23 extending beyond said relief, towards the median plane of the housing perpendicular to the bottom 15 of the housing.
  • the walls 16 then have a flat part 24 parallel to said plane, then a ramp relief 25 and then open into the housing 18 of the nut 19.
  • the parallelepiped base 2 When the clip 1 is in place in the hole in the housing, the parallelepiped base 2 is entirely contained in the mouth 17.
  • the portion of the branches 3 located beyond the stops 6 extends substantially in the vicinity of the flat part 24, the succession of reliefs and grooves being applied against the thread of the adjustment screw 10 and the end of the branches 3 being curved in the direction of the adjusting screw 10 under the action of the ramp 25.
  • the snap and the ramp effect preferably occur concomitantly.
