Definitions

  • connection terminal of a conductor to modular type electrical equipment, consisting of a housing formed by two assembled half-shells, or resulting from a cover / base assembly comprising a housing planned to accommodate said terminal.
  • a connection terminal has a cage housing a cooperating contact plate with a screw provided for bringing said plate apart or apart of one of the walls of the cage, in order to fix by clamping or release by loosening said conductor.
  • Modular electrical devices concerned by the invention generally have an even number of terminals used to connect to circuits in which they perform a function particular. These are, for example, circuit breakers, auxiliaries circuit breakers, contactors, etc.
  • the problem posed and resolved by the present invention relates to the maintenance of the cages in the housings.
  • the cages are in most cases arranged floating inside the housings provided in the boxes for welcome them.
  • Said housings being made up of two half-shells, the housings are distributed in these half-shells, divided in two half-housings located opposite, separated by the plane of separation of the half-shells.
  • the housing then remains joined during the tightening operation.
  • the rotational movement imparted to the screw is not transmitted to the cage due to its attachment to the housing and, in combination with the anchoring of the teeth in the half-shells, contributes to ensuring an effective tightening of the conductor without deformation of the insulating housing.
  • the object of the invention also consists in producing a terminal for connection which does not cause deformation of the case during the tightening operation, but without modifying the cage.
  • the contact plate housed in the cage which includes means for anchoring to the housing of the electrical equipment.
  • the torque exerted on the screw is transmitted to the half-shells so that they approach the level of their junction surfaces.
  • the means for anchoring the contact plate have teeth protruding towards stops made in said half-shells, intended to become embedded in said abutments progressively the exercise of the tightening torque on the screw.
  • the teeth are located on the edges of said contact pad oriented opposite the head of said screw, the tip of each tooth encrusting along an axis parallel to that of the screw, in the tightening direction axial of the latter.
  • each contact pad has at least one tooth cooperating with a surface of a stop that is substantially perpendicular in shape to the axis of the screw and located on each of the half-shells forming the housing.
  • the contact plate has a central body plane provided with two portions of ends perpendicular to said body, of which one is provided with lateral fins projecting from each side of said body central, one of the teeth being located on the end edge of the portion perpendicular without fin, offset to the side, the other tooth being located on the parallel edge of the fin located on the other side with respect to the axis longitudinal of the insert, the two teeth pointing in the same direction.
  • the contact plate has a U-shape of which the ends of the legs have lateral fins whose edges parallel oriented towards the base of the U each have a tooth, said teeth being located on either side of the longitudinal axis of said base of the U, a tooth also being located on the fin opposite the tooth.
  • connection terminal comprises a cage 1 housing a contact pad 2 whose movement relative to the cage 1 is caused by a screw 3.
  • the teeth 4, 5 projecting from the contact pad 2 are located on either side of the cage 1, and oriented along an axis parallel to that of the screw 3, points directed in the direction of tightening thereof.
  • the end portions 6, 7 of the clamping plate are oriented at opposite each other and therefore have opposite end edges. This is why, one of said portions is provided with lateral fins 8, 9 offering oriented edges like the end edge of portion 6.
  • each tooth 4, 5 is embedded in the clamping in stops molded in the half-shells. To that the main function of the invention is realized, it is important that each tooth cooperates with a stopper of a half-shell, hence their location substantially symmetrical with respect to a vertical longitudinal median plane cutting the contact plate 2, giving a representation equivalent to that of figure 2.
  • the terminal environment consisting of the housing 10 mounted in the half-shells 11, 12 and the elements located in the vicinity immediate said housing 10 are also shown.
  • the housing 10 mounted in the half-shells 11, 12 and the elements located in the vicinity immediate said housing 10 are also shown.
  • the geometry of the housing 10 for two main aspects.
  • each housing there are stops in which the points 4, 5 are anchored.
  • the stop associated with the half-shell 11 is referenced 13, while the stop of the other half-shell 12 bears the reference 14. Due to the almost anchoring contact pad 2 immediately from the start of tightening, said pad 2 is fixed, and the connection of the conductor with the terminal, obtained by the jamming of the stripped end of said conductor between plate 2 and one of the walls of the cage, can only be produced if said cage is movable in his home.
  • cage 1 there is a sliding of the only element still endowed with a degree of freedom in the housing 10, that is to say the cage 1, as the tightening or loosening.
  • cage 1 When no conductor is connected, cage 1 is located in the vicinity of the wall of the housing 10 closest to the base of the apparatus. In the clamping position, said cage 1 is on the contrary located at proximity of the wall of the housing 10 surrounding the screw 3.
  • the volume of the housing 10 is provided accordingly, and allows a movement of the cage 1 compatible with the tightening requirements.
  • all of the mechanical connections act as a classic motion transformer, transforming rotary motion printed on the screw 3 in a translational movement of the cage 1.
  • the two figures 3 and 4 are two opposite views from a single cutting surface. They clearly show the respective locations of teeth 4, 5 laterally with respect to the contact pad 2, so as to be locate each in a half-housing of each half-shell 11, 12.
  • figure 5 The main interest of figure 5 is to show the relative positioning axial of the cage 1 and of the contact plate 2.
  • the cutting plane, on the left side of the figure, go into tooth 5 which we see the exact positioning on the one hand with respect to the end portion 7, and on the other hand on the stop 14.
  • Figure 6 shows the elements of the previous figures 2 to 5, but in perspective. It highlights the cooperation of tooth 4 with the stop 13. It also specifies the configuration of the cage 1 / plate assembly. contact 2: cage 1 is housed in volume 10, while the portions ends 6 and 7 of the contact plate 2 are nestled outside said volume, and therefore do not hinder the travel of the cage 1 when it moves in rectilinear translation.
  • FIG. 7 represents a possible variant of the contact plate 2 '.
  • the end portion 7 ' is strictly identical to the portion 7 of the part described above, with two lateral fins 8 ', 9' and a tooth 5 'anchor.
  • the second end portion 6 ′ is positioned so that that it forms a U with the first. It has a 20 'notch allowing the addition of an additional tooth 21 'on a fin 22', in more than tooth 4 'identical to tooth 4 of contact pad 2 previously described.
