Definitions

  • the present invention relates to an electrical switching device and a module comprising a microswitch.
  • an electrical switching device of the type comprising a slide mounted movable in translation on a support, movable longitudinally relative to the support in a rest position, in a first active position, and in a second active position.
  • Such a device is used in particular to control a window lift of a motor vehicle.
  • the slide comprises coupling means with an operating member intended to be actuated by a user.
  • the device comprises fixed and movable frictional electrical contacts carried by the support and the slide.
  • the relative displacement of these contacts makes it possible to isolate an electrical member with respect to a power supply, to supply it according to a first direction of flow of the current, or to supply it according to a second direction of circulation of the current, opposite to the first.
  • the present invention aims to overcome these disadvantages by providing a switching device faster, more economical and resistant more effectively to wear.
  • microswitches with rapid contact break, or abrupt allows to obtain a fast switching, controlled during the translation of the slide, thanks to its cam profile.
  • the invention also relates to a module of the type comprising a microswitch, characterized in that it comprises connecting means for cooperating with complementary connection means of another module of the same type, these connecting means being in particular shaped like a dovetail, so as to form part of the support of a switching device of the aforementioned type.
  • this module comprises means for longitudinal positioning of the base, in particular at least one positioning stop of the base.
  • the longitudinal direction is the direction X and the transverse plane is the plane transverse to this direction.
  • An electrical switching device 10 is intended to control a window lifter or a sunroof of a motor vehicle. It comprises a slider 12, mounted to move in translation on a support 14, according to the longitudinal direction X in a rest position (shown in Figure 2), a first active position, and a second active position.
  • the switching device 10 generally defines a parallelepiped whose length is about 20 mm, the height of about 8 mm and the width of about 8 mm.
  • the slider 12 comprises means 16 for coupling with an operating member (not shown) intended to be actuated by a user, such as a window lifter button.
  • the support 14 comprises first 17 and second 18 modules, each comprising first 20 and second 22 micro-switches with rapid contact failure.
  • These microswitches 20, 22 are conventional, capable of operating in particular with a peak current of 30 amps and 17 amps continuously.
  • Each microswitch 20, 22 is provided with a control button 24, 26 movable in a vertical direction Z of the transverse plane, between a rest position (illustrated in FIG. 2) and an active position, in which the button 24, 26 is lowered so as to switch a control circuit of the window regulator or to directly power the motor of the window regulator.
  • transverse plane is defined by the direction Z and another direction Y orthogonal to the directions X and Z.
  • the two modules 17, 18 are of the same type, or even identical. They each comprise connecting means 19 intended to cooperate with complementary connection means of the other module. These connecting means 19 are in the form of a dovetail. Such a dovetail-shaped connection makes it possible to achieve perfect alignment along the X and Y axes of the modules 17, 18 and reduces the positioning tolerances of the two modules.
  • the device 10 further comprises a metal base 28, visible in FIG. 5, integral with the support 14, and two substantially vertically flexible members 30, 32 integral with the base 28.
  • Each flexible member 30, 32 is formed by an elastic tongue cut into the base 28, having an end secured to the base and an opposite end free of cooperation with the control button 24, 26 corresponding.
  • the base 28 and the support 14 are provided with complementary means of longitudinal and transverse positioning of the base relative to the support, comprising positioning stops.
  • the longitudinal positioning means comprise positioning stops 34 formed on the support 14, consisting of bosses arranged on the upper surface of each module 17, 18, and cooperating with a transverse portion 36 of the base 28, so as to block this transverse portion 36 between the stops 34.
  • the transverse positioning means comprise transverse immobilization wings 38 formed on the base 28. They also comprise means of the groove and tongue type, namely grooves 40 formed on projections 42 of the support 14, and edges 41. arranged on the base, visible in Figures 3 and 5.
  • the device 10 also comprises complementary means for guiding the slider 12, more precisely guide means of the groove and tongue type.
  • the guide means are carried by the support 14 and the slider 12. They comprise tabs 44 formed on the projections 42 of the support 14, cooperating with grooves 46 formed on the slider 12 In this embodiment, the projections 42 of the support bear both the transverse positioning means 40 of the base and the means 44 for guiding the slide.
  • the slider 12 comprises a cam profile 56, provided with first 58 and second 59 bosses, visible in Figure 2. This cam profile 56 cooperates with each of the control buttons 24, 26 via flexible members 30 or 32.
  • the slider 12 also comprises a cavity 60 delimited by first 62 and second 63 transverse walls.
  • the slider 12 also includes two ramps 64 for its mounting on the support.
  • the slide is initially in its rest position, visible in FIG. 2, in which the two control knobs 24, 26 are in the rest position.
  • the coupling means 16 drive the slider 12 so as to make it undergo a translation in the longitudinal direction, by example following the direction indicated by the arrow 66.
  • the first control knob 24 is operated by cooperation with the first boss 58, via the tongue 30. More specifically, the boss 58 imposes a vertical movement of the free end of the tongue 30 When the translation of the slider 12 is sufficient, the vertical movement of the tongue 30 is of sufficient amplitude to move the button 24 of its rest position to its active position. This position defines the first active position of the slider 12.
  • the second boss 59 imposes a vertical movement of the free end of the tongue 32 and thus cooperates with the second control button 26.
  • the button 26 moves from its rest position to its active position, which defines the second active position of the slider 12.
  • the stroke of the slider 12 is limited by the two walls 62, 63 which each cooperate with one of the tongues 30, 32.
  • the wall 63 forms a limit stop cooperating with the tongue 32.
  • the stroke of the slide is about 4 mm on each side.
  • the two modules 17, 18 are assembled together so as to form the support 14 visible in FIG. 4.
  • the base 28 is mounted on the support, in the vertical direction, making all first pass the projections 42 through cutouts 68 formed on the base 28, and arranging the wings 38 around the support 14.
  • the base 28 is thus immobilized in the longitudinal direction and in the transverse plane.
  • the slide 12 is mounted on the support, in the longitudinal direction, by firstly cooperating with the first tabs 44 of the support (on the left in FIG. 5) with the grooves 46 of the slide 12, then sliding the slider 12 to its rest position one of the ramps 64 retracting the tongue 32 visible in Figure 2.
  • the complementary guide means of the slider 12 are carried by the base 28 and the slider 12.
  • These guide means comprise tabs 70 formed on projecting cutouts of the base 28, cooperating with the grooves 46 of the slide 48.
  • the tongues 70 comprise longitudinal ends 72 intended to immobilize the tongues 70 in the grooves 46.
  • modules 17, 18 are particularly interesting from the point of view of production costs, especially since these modules 17, 18 can be used as usable micro-switch boxes. for other switching devices than the subject of the invention. It can be seen for this purpose that the modules 17, 18 each comprise a keying means, comprising a chamfer, usable in the case where the module 17, 18 is used in isolation.
