Definitions

  • the invention relates to contactors which comprise: at least one relatively rigid conductive contact blade, one end of which is mounted so as to be able to rotate about a fixed axis relative to an insulating housing, so that this blade can pivot between two extreme angular positions for the first of which the other end or free end of this contact blade is spaced from a fixed contact pad but for the second of which this latter end is in contact with this pad; elastic means continuously exerting on the contact blade an approximately longitudinal thrust, directed towards said fixed axis; and a control element capable of temporarily exerting on the blade, against the action of a return means, a force capable of passing the contact blade from the first to the second of the above extreme positions, the return means then causing the contact blade to return to the first of its extreme positions.
  • Such contactors are well known but they are of a relatively complicated construction and assembly and therefore of too high a cost price.
  • their control element is of the type actuated directly by the user, they do not give the user a feeling touch of the contactor closing, at the arrival of the free end of the contact blade on its stud.
  • the object of the invention is in particular to remedy these drawbacks of known contactors.
  • the contactor according to the invention is essentially characterized in that the elastic means acting on the contact blade and the return means acting on the control element are combined in a single elastic blade, one end of which is held by the housing and the other end of which is connected to an intermediate part of the contact blade and in that the elastic blade is bent under elastic tension according to an arcuate transverse profile having its convexity towards the control element, which is arranged to act by pushing on an intermediate part of this elastic blade.
  • the contactor is thus composed of only three moving parts, namely the control element, the relatively rigid contact blade and the elastic blade, and its assembly is therefore simple as will be explained in more detail using the figures.
  • the control element exerts its action in the direction of application of the contact blade towards its stud, the user experiences a tactile sensation when the contactor closes when this control element is of the directly actuated type. by the user.
  • the elastic blade has a tongue which is preferably made in one piece with this blade and which projects towards the control element to cooperate with it and the housing comprises stop means limiting the return movement of the control element.
  • the presence of this tab has the effect of sparing the elastic blade from excessive deformation when the contacts are closed.
  • the contactor comprises, in known manner, a contact blade 1, relatively rigid, one of the ends 2 of which is mounted so as to be able to rotate about an axis X - X which is fixed relative to an insulating housing 3.
  • the contact blade 1 can thus pivot between two extreme positions shown respectively in FIGS. 1 and 2.
  • FIGS. 1 and 2 For the first of these positions (FIG. 1), the free end 4 of the contact blade 1, opposite to the end 2 is spaced from a contact pad 5 whose tail 6 is partially embedded in the housing 3 during the molding thereof and emerges from the bottom of this housing to form a connection terminal.
  • the free end 4 of the contact blade 1 is in contact with the stud 5.
  • the contactor comprises a control element preferably manual and such as a push button 7 which is guided in translation relative to the housing 3 and whose return movement (upwards of FIGS. 1 and 2) is limited by means stop (not shown).
  • a control element preferably manual and such as a push button 7 which is guided in translation relative to the housing 3 and whose return movement (upwards of FIGS. 1 and 2) is limited by means stop (not shown).
  • An elastic blade 8 is combined with this relatively rigid contact blade 1, one end 9 of which is fixed relative to the housing 3 and the other end 10 of which is connected to an intermediate part of the contact blade 1.
  • This elastic blade 8, which may or may not be of electrically conductive material, is bent under elastic tension according to an arcuate profile having its convexity towards the control element or push button 7 (see FIGS. 1 and 2), which is arranged to act by pushing on an intermediate part of the elastic blade.
  • the end 9 of the elastic blade 8 is forked and has two branches 11 defining a notch 12 whose role will be explained below.
  • the end of each branch 11 is engaged in a housing 13 provided in the housing 3, which gives the end 9 a fixed position relative to the latter.
  • the latter has an opening 14 of closed outline, for example rectangular, in which is engaged the end 10 which has the shape of 'A spout and which is provided with a suitable shoulder to limit its insertion into the opening 14.
  • the contact blade 1 is pushed into a notch 15 formed in a terminal 16 whose tail 17 is mounted in the housing 3 like that 6 of the pad 5.
  • the notch 15 is shaped so as to allow the contact blade 1 to pivot around the axis XX.
  • the contact blade 1 has two lateral spouts 18 which keep it centered relative to the terminal 16.
  • the elastic blade 8 has a tongue 20 which is obtained by cutting this blade 8 and which projects towards the push-button 7, so as to cooperate with a projection 21 thereof.
  • the tongue 20 leaves tangentially from the vicinity of the bottom of the notch 12 of the elastic blade 8, with a less curvature than that of this elastic blade, as can be seen from FIGS. 1 and 2.
  • a contactor is thus obtained, the method of mounting and operation of which are as follows.
  • the elastic blade 8 slightly relaxes by abruptly driving the contact blade 1 towards the cut-off position shown in FIG. 1 and by raising the push button 7, by means of the tongue 20.
  • the only elastic blade 8 thus performs the following functions: - Print the contact blade 1 a movement in accordance with the control movement received from the operating member 7, which allows it to close and open the contact; - Give this movement a high speed, independent of the speed of movement of the operating member 7, when the contact blade 1 joins the fixed stud 5 and when it deviates from it; - in the closed contact position ( Figure 2), press the contact blade 1 on the fixed stud 5 with a force allowing the requested performance to be obtained; - in the open contact position ( Figure 1), maintain the contact blade 1 in this position, in accordance with the required performance; - Apply to the operating member 7 a force recalling it and keeping it in the rest position ( Figure 1) when it is not actuated.
  • the elastic blade 8 works thanks to the elasticity of the material which constitutes it (which can be mineral or organic, electrically conductive or insulating).
  • the end 9 of the elastic blade 8 has been shown and described as capable of pivoting with respect to the housing 3, it can also be embedded in the latter without the operation of the contactor being modified.
  • the elastic blade 8, especially when it is made of a material which does not conduct electricity, can be associated not with a single contact blade, as described above and shown, but with several blades. contact 1 mounted in parallel.
