Definitions

  • the invention relates to a normally closed type electrical switch comprising an elastically deformable blade which causes a change of state of the electrical switch in response to the application of an actuating force on the elastically deformable blade and in which, in In the absence of application of an actuation force, the electrical switch is maintained in a closed state.
  • US 9,218,926 B1 “describes an electrical switch of the normally closed type, comprising a casing, which comprises an upper part and a complementary lower part, which carries a fixed internal contact track, an internal contact blade, which is carried by the upper part and which is elastically deformable to occupy a high rest position to establish an electrical switching path, an unstable low position in which the electrical switching path is interrupted and an actuator for controlling the deformations of the internal blade, which is pivotally mounted around a horizontal axis, between the rest position and an angular actuation position, in which the internal contact blade is in its first position.
  • the latter During the first use causing at least a first change of state of the electrical switch, the latter returns at least temporarily to its closed state in which the electrical switching path is established.
  • Such a design can be inconvenient, in particular when the electric switch is assembled on an electronic card comprising a battery or electric cell. Indeed, before being integrated into the electronic device, the electric switch is not activated and it is in its closed state, which causes consumption of the energy accumulated in the battery or electric cell of the device.
  • the invention aims to provide a solution to this problem by proposing an electrical switch comprising means for locking in the open position, that is to say in a state in which the electrical switching path is interrupted.
  • the invention also aims to provide such an electric switch which is of compact design, and which makes it possible to absorb an overtravel of actuation.
  • the invention also aims to propose a switch which can be unlocked automatically when it is carried by a sub-assembly which is put in place and assembled in an electronic device.
  • the invention also proposes an assembly comprising an electronic card and a switch according to the invention, characterized in that the electrical switch is mounted on one face of the electronic card and is adjacent to an edge of the electronic card so that, if the assembly is placed in an electronic device, the internal contact blade of the electrical switch is automatically unlocked by its actuator coming into contact with a part facing the electronic device , or belonging to assembly means.
  • the longitudinal axis L is oriented from the rear to the front.
  • FIG. 1 We represented at figures 1 to 5 an exemplary embodiment of an electrical switch 100 which here has a general design symmetry with respect to the median vertical and longitudinal plane PVM indicated in picture 3 .
  • the electrical switch 100 comprises a housing 10 in two upper 12 and lower 14 parts which houses a double internal contact blade 16 and an actuator 18.
  • the upper part 12 is a molded part made of insulating plastic material of generally rectangular parallelepipedic shape and which defines an internal housing 20 delimited by a horizontal upper wall 22, two vertical and longitudinal side walls 24, and by a vertical and transverse front wall 26.
  • the rear transverse face 28 is open, as is the horizontal underside 30.
  • the upper wall 22 comprises a through central opening 32 which is delimited by an inclined front transverse edge 34, by an inclined rear transverse edge 36 and by two longitudinal vertical faces 38 of longitudinal orientation.
  • the internal face 23 of the upper wall 22 here comprises two vertical studs 40 for fixing by hot crimping the internal contact blade 16, which are arranged longitudinally close to the open rear transverse face 28.
  • the open lower face 30 comprises three vertical studs 42 arranged in a triangle for fixing the lower part 14 by hot crimping.
  • each side wall 24 includes a concave semi-cylindrical housing 44 which opens vertically downwards.
  • the upper wall 22 Transversely on either side of the central slot 32, and substantially at mid-length, the upper wall 22 comprises a locking lug 46 with a substantially V-shaped profile.
  • the locking lugs 46 are slightly offset longitudinally forward relative to the central axis A of the housings 44 (see figure 10 ).
  • the lower part 14 of the box 10 is here a piece of conductive metal sheet which is produced by cutting and bending.
  • the lower part comprises a horizontal rectangular lower plate 50 which is extended laterally by two vertical and longitudinal side cheeks 52.
  • the dimensions of the lower part 14 are complementary to those of the upper part so that, in the assembled position, the side flanges 52 each extend along an outer face 25 of a side wall 24, and substantially on the full height of the top 12.
  • each side flange is extended by an electrical connection lug 56 which extends outwards in a vertical and transverse plane.
  • the horizontal lower plate 50 comprises three holes 60 arranged in a triangle, each of which is crossed vertically by a vertical stud 42 of the upper part 12.
  • the horizontal lower plate 50 comprises two branches 62 of elastic return.
  • Each return branch 62 is produced by cutting and bending and its active front free end section 64 is folded inwardly of the internal housing of the upper part 12 of the casing 10.
  • each return branch 62 is able to deform elastically, in particular downwards.
  • the elastic return branches 62 are shown in their elastically unconstrained state.
  • the internal contact blade 16 is here a double blade, of symmetrical design with respect to the plane PVM, which is produced in a conductive metal sheet by cutting and bending.
  • the two internal electrical contact blades themselves are interconnected by a horizontal crosspiece 66 for fixing.
  • the crosspiece 66 For fixing each internal electrical contact blade, the crosspiece 66 comprises two holes 68 spaced apart transversely and each of which is crossed vertically by a vertical stud 40 of the upper part 12.
  • Each internal contact blade 16 comprises, successively and longitudinally from rear to front, a rear fixing section 70, an intermediate actuation section 72 and a front contact section 74.
  • the rear fixing section 70 to which the crosspiece 66 is attached for its fixing under the lower face 23 of the upper wall 22 of the upper part 12 of the casing 10, here extends horizontally.
  • Each rear attachment section 70 is here extended longitudinally towards the rear by an external electrical connection section 76 which is here shaped as a tapping pin which projects longitudinally beyond the open rear transverse face 28.
  • each intermediate actuation section 72 extends horizontally in the extension of the sections 70 and 76, inside the housing 20, substantially halfway up (See figure 9 and 10 ).
  • Each actuation section 72 is delimited by a flat lower face 73.
  • each intermediate actuation section 72 is extended forward by a front contact section 74 which is inclined vertically downwards and which ends in an angled end 78 whose convexity is oriented towards the internal upper face 51 of the horizontal lower plate 50.
  • each front contact section 74 is shaped in such a way that its bent free end 78 is in elastic contact support towards the bottom against a portion facing the upper face 51 of the lower plate 50.
  • This portion facing the upper face 51 of the lower plate 50 constitutes a fixed lower electrical contact track to establish a electrical switching path between the lower plate 50 and its electrical connection lugs 56 on the one hand, and the connecting sections 76 on the other hand.
  • This upward movement is obtained by elastic deformation of the internal contact blades 16 by acting on the intermediate sections 72 for actuation.
  • Actuator 18 generally takes the form of an internal transverse actuation shaft 80 and a drive arm 82.
  • the internal shaft 80 and its drive arm 82 are here produced in a single piece by molding in plastic material.
  • the internal transverse shaft For its rotational mounting, pivoting in both directions, relative to the housing 10, the internal transverse shaft comprises, at each of its two opposite transverse ends, a cylindrical journal 84 which is received in rotation, almost without play, in a complementary housing 44 of the upper part 12 inside which it is held imprisoned by the lower plate 50.
  • the actuating shaft is thus mounted for rotation around the axis A.
  • the internal shaft 80 is extended by a rectilinear arm for driving in rotation.
  • drive arm 82 extends vertically through central lumen 32 above top wall 22.
  • the drive arm 82 is slightly offset longitudinally rearward relative to the vertical plane passing through the axis of rotation A.
  • the transverse width of drive arm 82 is slightly less than the transverse width of central lumen 32.
  • the maximum angular positions that the actuator 18 can reach in both directions correspond to the coming into abutment of the drive arm 82 with the inclined front transverse edge 34 or with the inclined rear transverse edge 36.
  • the internal shaft 80 comprises a locking lug 86 which is capable of cooperating with a locking notch 46 facing each other.
  • the upper end of the cylindrical profile of the locking lug 86 is slightly offset longitudinally forwards and extends opposite the associated locking notch 46.
  • the assembly consisting of a locking lug 46 and a locking notch 86 constitutes means for locking the drive arm 82, and therefore the double internal contact blade 16, in its second stable high position in which the electrical switching is interrupted.
  • each control cam 88 is generally triangular and has a flat horizontal upper section 92 which ends in a front elbow 94 and a rear elbow 96 for control.
  • Each bend 94, 96 is in the form of a convex cylinder arc.
  • the front elbow 94 is extended downwards by an inclined plane section 98.
  • Each cam 88 is arranged transversely in line with a return leg 62 and each inclined plane section 98 of the cam profile extends with play opposite an active front free end section 64.
  • the upper face of the flat horizontal upper section 92 extends here with a slight vertical play by relative to the lower face 73 of the associated actuation section 72.
  • the switch 100 is shown in a rest position in which the electrical switching path is established by each of the two front contact sections 74 of the internal double contact blade 16, each internal blade 16 being in a low position with respect to bottom plate 50.
  • NC normally closed NC of the electrical switch.
  • This pivoting causes the cooperation of the rear control elbow 96 with the associated actuation section 72 of the internal blade 16 and a lifting of the front contact section 74.
  • the opening of the electrical contact 51-78 is almost immediate, but the angular actuation stroke by pivoting of the actuation arm 82 can be continued.
  • the electrical switch 100 thus has a capacity to absorb a large actuation overtravel.
  • This position or state NOi is unstable because, as soon as one ceases to apply an actuating force to the actuating arm 82, the actuator 18 is elastically returned to its central angular position of rest by the action of the recall branches 62.
  • This pivoting causes the cooperation of the front control elbow 94 with the associated actuating section 72 and a lifting of the front contact section 74 of each internal blade 16.
  • Each internal blade 16 is then in a second high position relative to the lower plate 50.
  • the opening of the electrical contact 51-78 is almost immediate. It is a second stable open position NOs of the electrical switch in which the electrical switching path is interrupted.
  • This position or state NOs is stable because, when an actuating force is ceased to be applied to the actuating arm 82, the latter remains angularly locked by the locking means 46-86.
  • the drive arm 82 has caused an elastic deformation of the upper partition to retract the locking notch 46 and cause the locking lug 86 to pass angularly to the other side.
  • the drive shaft 80 is then again in its central angular position and the electrical switching path is restored.
  • the double design of the internal blade 16 of contact makes it possible, for certain applications, to have contact redundancy which is useful if, for example, the electrical switch is not sealed and that an impurity is introduced between the free end 78 and the upper face 51.
  • the internal contact blade 16 is simple, that is to say it comprises only one part with an intermediate actuation section 72 and a front contact section 74, 78.
  • the other section 72' of symmetrical design and similar to that of the actuation section 72, is not extended by a contact section and therefore has no function of establishing or interrupting an electrical contact.
  • the locking notch 46 is a window which is formed in an elastically deformable tab 99 which is made centrally in the lower plate 50, transversely between the two elastic return branches 62.
  • the complementary locking lug 86 is formed at the bottom of the actuator 18.
  • the drive shaft 80 includes a beak-shaped lug which is adapted to be received in the window 46 when the electrical switch is locked in its stable state. open NOs (See figure 21 ).
  • the rear profile of the locking pin 86 is shaped to allow unlocking.
  • the lower plate 50 comprises two tapping pins 56 which protrude longitudinally beyond the open rear transverse face 28, like the electrical connection sections 76 of the internal contact blade.
  • an electrical switch 100 can be mounted on a face 104 of an electronic card comprising in particular a printed circuit board 102 which is delimited by an edge 106 to form an assembly 200.
  • Switch 100 is adjacent to edge 106 of plate 102 and, as can be seen in figure 23 , the outer face of its wall 22 is substantially aligned with the edge 106.
  • Such mounting and positioning of the electrical switch 100 can, if the assembly 200 is placed in an electronic device (not shown) in the direction indicated by the arrow F of the figure 23 , enable automatic unlocking of the electrical switch 100 by the actuation arm 82 coming into contact with a part facing the electronic device, or belonging to automated assembly means.
