Definitions
- the invention relates to an electromagnetic trip device comprising, in a housing comprising a base capped with a cover, a circuit electromagnetic including a fixed armature resting on the base, thus a movable armature capable of opening and closing the circuit electromagnetic, said fixed armature being taken between the base and the cover.
- An electromagnetic trip device of this type is known from the document FR-A- 2 630 256, according to which the fixed armature is secured to the housing in being wedged between the base and the carcass of a coil threaded on the frame fixed, the carcass itself being sandwiched between the cover and the fixed frame.
- the application of the fixed frame against the base is likely to cause uncontrolled stresses and deformations in the latter may cause improper positioning of the fixed frame, which affects the correct operation of the trigger.
- An object of the present invention is to resolve in particular the disadvantages mentioned above by proposing an electromagnetic trip device which, all being simple in design, has reliable, precise operation, sustainable.
- the invention proposes a electromagnetic trip device as presented in the introduction, characterized by that the base includes an elastically deformable zone capable of sinking under the pressure of the fixed reinforcement, the dimensions and the conformation of the base, of the cover and of the frame being able to allow the tightening of the frame between the cover and said deformable zone which urges it towards the cover under the effect of its own elasticity.
- the pawn occupies a middle position in said deformable zone, which allows a distribution substantially uniform stresses in the deformable zone.
- the carcass of the coil being integral with the fixed frame, it is likely to transmit its own constraints and deformations to it, especially when assembling the trigger, when welding the wires of the coil on its pins, or during installation of the trigger, during of which intervene the pins.
- the fixed frame is thus likely to be veiled, or folded, which can affect the air gap between the reinforcements and, in any event, proves harmful to the proper functioning of the trigger.
- An additional object of the present invention is to solve in particular the disadvantages which have just been exposed, by proposing a electromagnetic trip device whose design allows at least to limit the impact of external stresses on the fixed reinforcement.
- the invention proposes a electromagnetic trip device comprising, in a housing comprising a base capped with a cover, an electromagnetic circuit comprising a fixed armature resting on the base, as well as a movable armature susceptible to open and close the electromagnetic circuit, said fixed armature being taken between the base and the cover, the trigger further comprising a coil comprising a carcass on which a winding is wound, said carcass being threaded on the fixed and integral frame of the housing, characterized in that the carcass is rigidly mounted relative to the housing and floating relative to the fixed frame.
- the fixed frame is preserved in particular from inevitable or accidental stresses and deformations suffered by the coil.
- the trigger is thus more reliable, more resistant, and this in a way sustainable.
- an electromagnetic trip device 1 to high sensitivity for a switch or circuit breaker which includes, in a case 2 assumed to be fixed, composed of a base 3 capped with a cover 4, a circuit electromagnetic 5 comprising a fixed frame 6 in the shape of a U, secured the housing 2 and a movable frame 7 called a pallet, capable of rotate to open or close the electromagnetic circuit 5.
- trigger 1 is described with reference to this mark, according to the orientation adopted in FIG. 2, which corresponds to the usual use most common of trigger 1.
- the fixed frame 6 and the pallet 7 are both produced in a ferromagnetic material, such as an Iron - Nickel alloy.
- the fixed frame 6 comprises a first branch 8 called front and a second branch 9 called rear, connected by a base 10 resting on the base 3 case 2.
- the electromagnetic circuit 5 comprises a coil 11 comprising a carcass 12 on which a coil 13 is wound, the carcass 12 being threaded on the front branch 8 of the fixed frame 6 and secured to the base 3.
- the magnet 14 for the magnetic polarization of the fixed armature 6.
- the magnet 14, shaped parallelepiped, is fixed by one of its ends on the base 10 of the fixed armature 6, preferably by welding. More specifically, the magnet 14 is fixed on an upper face 15 of the base 10, which also has a face lower 16 opposite.
- Pallet 7 is likely to occupy at least two equilibrium positions stable, i.e. a working or engaged position, in which it found pressed against the branches 8, 9 of the fixed armature 6 and closes the circuit electromagnetic 5, and a rest or triggered position, in which it is moved away from the fixed armature 6 and opens the electromagnetic circuit 5.
- Pallet 7 is biased towards its position triggered by a spring 17 of recall operating in traction.
- Pallet 7 has two opposite parallel flat faces, namely a upper face 18 and a lower face 19.
- the free ends 20, 21 respectively of the front 8 and rear 9 branches form polarization surfaces located substantially in the same plane polarization P, with which the face cooperates in the engaged position lower 19 of pallet 7.
- Pallet 7 has the shape of a trident and has a body 22 of shape rectangular of which project two lateral wings 23, 24 bent backwards, and whose rear edges 25 are bevelled to form knives 26 for the articulation of the pallet 7.
- Each knife 26 has an inclined face 27 facing upwards, terminated downwards by an edge 28 situated substantially in the plane of the lower face 19 of the pallet 7.
- the edges 28 together form an axis A of pivoting of the pallet 7.
- the rear branch 9 which has a front face 29 and a face rear 30 opposite, is fixed by snap-fastening or by any other means equivalent to a plate 31 guiding the pallet 7, the latter being pivotally mounted relative to the plate 31.
- This plate 31 is a single piece produced for example in a metallic material for stiffness. It has a plated body 32 against the rear face 30 of the rear branch 9, which it substantially covers. This body 32 is extended upward, in the form of a fork, by two legs upper 33, 34 similar which protrude from the fixed frame 6 projecting from the plane of polarization P, arranged opposite the wings 23, 24 of the pallet 7, and against which the knives are applied 26.
- each tab 33, 34 has a front face 35 support against which is applied, under the action of the return spring 17, the edge 28 of the knife, 26 in the engaged position ( Figure 4).
- the pallet 7 In the triggered position, the pallet 7 is in linear contact, through its body 22, with the rear branch 9, the lower face 19 of the pallet 7 being in abutment on a rear edge 36 of the free end 21 of the rear branch 9 ( Figure 5).
- the pallet 7 has, at its wings 23, 24, a transverse extension greater than that of the rear branch 9, the knives 26 being permanently separated laterally therefrom.
- the knives 26 never being in contact with the rear branch 9, they do not produce, during possible wear, no particles liable to deposit on the polarization surface 20, 21.
- Pallet 7 has a tail 37 towards the rear which extends beyond wings 23, 24 projecting from them, which is, being free to move, between the legs 33, 34 of the plate 31, and in which is anchored one of the upper 38 ends of the return spring 17.
- This upper end 38 of the return spring 17 forms a loop inserted in a through hole 39 made in the tail 37, beyond the edges 28 towards the rear, so as to form a cantilever allowing the pivoting of the pallet 7, under the action of the spring 17, around the axis A formed by its edges 28.
- the plate 31 ends down with a folded lower tab 40 backwards, in which the other lower end 41 of the spring is anchored recall 17.
- the upper legs 33, 34 are each extended, upwards, by a bent extension 42 forming a hook defining a housing 43 likely to receive the pallet 7.
- the hook 42 comprises, towards the rear, an inclined bottom 44 connected to the tab 33, 34 by a part 45 folded back at right angles to the tab 33, 34, and, upwards, a return 46 folded at right angles to the front relative to the background 44.
- the bottom 44 has a bearing surface 47 facing forward and towards the top, while the return 46 has a bearing surface 48 facing the fixed armature 6, that is to say towards the front and down.
- Pallet 7 is likely to occupy a third position of equilibrium stable, called lifted, in which it is inclined and is separated from the fixed armature 6 beyond the rest position, and in which it cooperates with the hook 42 being received in the housing 43 ( Figures 6, 7, 8).
- the tail 37 of the pallet 7 has, towards the rear, an end portion 49 reduced transverse extension delimited forwards by two recesses lateral 50, 51 forming stops.
- Pallet 7 can be moved to its raised position from its position triggered by the action, for example, of an automated gripping device (not shown), which comes to grip the pallet 7 in the triggered position then, pulling on the spring, place the pallet 7 in the raised position in cooperation with the housing 43.
- an automated gripping device not shown
- the pallet 7 can be restored to the triggered position - or directly in the engaged position - from the raised position, by the same automated gripping device, which, coming to grip the pallet 7, away from the housing 43 by pulling on spring 17 and then depositing it on the fixed frame 6.
- the spring 17 is slightly tilted back, from top to bottom.
- This cleaning which takes place in particular when the trigger 1 is mounted, can be performed by ultrasound, by spraying, in particular by cryogenic spraying such as a jet of carbon dioxide, or by any other known equivalent process of the skilled person.
- the parts 45 of the hooks 42 folded backwards each have a recess 52 inwards, which the pallet 7 bypasses during its passage from the triggered position to the raised position, before coming press against the bottom 44 of the hook 42.
- the plate 31 has, in its lower part, means latching integrated in the form of two arms 54, 55 projecting from the body 32 in its lower part, made of material with it and folded at right angles to the front, and which surround the rear branch 9 near the base 10 of the fixed frame 6.
- the arms 54, 55 are arranged between, on the one hand, upwards, two ears 56, 57 projecting transversely of the rear branch 9 approximately halfway up the latter, and on the other hand, towards the bottom, the base 10 of the fixed frame 6.
- Each arm 54, 55 also has, on its upper edge at vicinity of the body 32, a bump 53 projecting upwards and which, under the effect of the tension of the spring 17 on the plate 31, is in abutment against a face lower of the corresponding ear 56, 57 so as to make up for the clearances elevation likely to appear between the plate 31 and the fixed frame 9.
- the arms 54, 55 are resiliently flexible, and each has a boss 58 projecting inwards.
- each arm 54, 55 is made, at the level of the boss 58, a U or V cut delimiting a tooth 59 which projects from the arm 54, 55 towards the body 32 of the plate 31, and has a bearing surface 60 facing the rear looking at the body 32.
- the plate body 32 has, facing and in line with the teeth 59, a tongue 61 formed by a V-shaped cutout in the plate body 32 and which, in the absence of stress, is tilted forward.
- the tongue 61 has a certain elasticity so that, in position latched, the rear branch 9 is clamped between the teeth 59 and this tongue 61.
- the conformation of the plate 31, in particular of the arms 54, 55, by compared to the fixed frame, is thus capable, by itself, of allowing rigid fixing by snap-fastening, of the plate 31 on the fixed frame 6.
- the base 3 and the cover 4 are two monobloc pieces each produced by molding a synthetic material such as PVC, polypropylene, polyoxymethylene, or equivalent.
- the base 3 comprises a bottom wall 62 on which the circuit rests electromagnetic 5, bordered by two side walls 63, 64 facing each other, of which protruding teeth 65 outwards for the snap-fastening of the cover 4.
- the side walls 63, 64 extend forwardly beyond the wall of bottom 62, and the base 3 has, at the front, a hole 66 passing through in section rectangular, extended from one wall 63 to the other 64.
- This hole 66 is bordered forwards by a crosspiece 67 forming the end front of the base 3, and towards the rear by a partition 68 which separates it from the wall of background 62.
- the base 3 also has two identical pairs of nipples 69, 70 arranged transversely opposite, at each of the junctions between the base 3 and the side walls 63, 64. Each pair comprises a first 69 and a second 70 nipples protruding upwards and inwards, at the junction between the side wall 63, 64 and the bottom wall 62.
- the first stud 69 located near the partition 68, has transverse and elevation dimensions respectively greater than and less than those of the second nipple 70.
- Each nipple 69, 70 is rounded inward, the nipples 69, 70 together delimiting, at the level of the bottom wall 62, a reception area 71 of the base 10 of the fixed frame 6.
- the bottom wall 62 has, at the level of the reception area 71, a zone 72 elastically deformable, this zone 72 being more particularly able to sink elastically downwards under the effect of a pressure which would be applied from top to bottom.
- the base 3 has, near the center of this deformable zone 72, a pin 73 which projects from the bottom wall 62 upwards and has one end free 74 forming a localized bearing surface relative to the deformable zone 72.
- this zone 72 is here inscribed in a circle inside which the bottom wall 62 has a conical section with a taper facing downwards, the bottom wall 62 tapering from the edge of said circle to its center - that is to say at the right of pawn 73.
- the cover 4 is in turn a hollow part, generally in the form parallelepiped, having an upper wall 75 bordered by a wall front 76, a rear wall 77, and two side walls 78, 79 which define together, downwards, an opening 80 through which the cover 4 is intended to be associated with the base 3.
- each side wall 78, 79 has two legs 81 paired in each of which is made a window 82 intended to cooperate with one of the teeth 65 of the base 3 to produce snap on cover 4.
- each side wall 78, 79 has a notch 83 between the legs 81, intended to cooperate with a complementary bead 84 in projecting outwards on each side wall 63, 64 of the base 3.
- Each side wall 78, 79 of the cover 4 also has a inner surface 85 along which runs a rib 86 projecting towards the interior, which extends from the upper wall 75 towards the opening 80.
- This rib 86 has a lower end portion 87 projecting from the notch 83 downwards, terminated by a surface 88 forming a stop.
- the fixed armature 6 When mounting the trigger 1, the fixed armature 6 is placed on the base 3, its base 10 being placed in the reception area 71, which is complementary, by being inserted between the nipples 69, 70 which frame the area deformable 72 and which, forming shims, limit the longitudinal travel and possibly transverse of the fixed frame 6, limiting the travel transverse which can also be produced by the side walls 63, 64.
- the underside 16 of the base rests on the pin 73 while being in contact with the bearing surface 74 thereof, which is of limited area with respect to that of the deformable zone 72 in order to concentrate the stresses.
- the latching of the cover 4 on the base 3, with the stop 88 of the rib 86 looking at the deformable zone 72, causes, by the dimensions and the conformation of the base 3, of the cover 4 and of the base 10 of the fixed frame 6, the support of this stop 88 against the upper face 15 of the base 10 against stress on the deformable zone 72.
- the base 10 is then clamped, maintained, immobilized in elevation between the pin 73 and the rib 86, the deformable zone 72 urging, under the effect of its own elasticity, the base 10 towards the cover 4.
- base 10 presses on pin 73, which causes the deformable zone 72 to sink in and, by the elasticity of this last, the catching up of games likely to appear between the base 10 of the fixed frame 6, the base 3, and the cover 4, and the precise positioning of the fixed frame 6 relative to the housing 2.
- the cover 4 has, on its front 76 and rear 77 walls, two fixing lugs 89, 90 perforated or hollowed out in the shape of an ear, for securing trigger 1 on a protective device bistable differential (not shown) capable of being actuated by the trigger 1.
- the trigger 1 comprises an actuating device 119 which includes a pusher 114 inserted in a through hole 115 made in the upper wall 75 of the cover 4, in line with the body 22 of the pallet.
- the pusher 114 comprises an upper end portion 116 projecting from the upper wall 75 towards the outside and capable of cooperating with the device differential protection, and a lower end 117 projecting from this wall 75 inwards, and the end of which forms or carries a head 118 hemispherical capable of cooperating with the pallet body 22.
- trigger 1 The operation of trigger 1 is briefly described.
- Pallet 7 is assumed to be in its engaged position, the pusher 114 being in a so-called depressed position where the head 118, which is bearing against the pallet body 22, is at a distance from the wall 75 ( Figures 2, 3).
- the pusher 114 Under the action of an external mechanical stress applied to the upper end part 116, and directed from top to bottom, the pusher 114 returns to its depressed position by forcing the pallet 7 to occupy its position engaged.
- the elevation position of the pusher 114 depends on the positioning in elevation of the reinforcements 6, 7, that is to say, taking into account the fact that the pallet 7 is caught between the pusher 114 and the fixed frame 6, of the positioning of the fixed frame 6 relative to the housing 2. This positioning being precise, as we saw above, the precision of the positioning of the pusher 114 relative to the housing 2 is therefore ensured.
- the carcass 12 includes a lower flange 91 and an upper flange 92 framing the winding 13, connected by a hollow core 93 threaded on the front branch 8, and having a through hole 94 whose shape is complementary to it.
- the carcass 12 further comprises a foot 95 of rectangular section which projection of the lower flange 91, down.
- Carcass 12 is assembled at base 3 by pressing his foot 95 into the hole 66.
- the dimensions relative of foot 95 and hole 66 are chosen so that, once pressed into the hole 94, the foot 95 is mounted tightly in the latter, so that the carcass 12, once assembled, be held firmly in a position predetermined fixed.
- the base 95 has two through holes 96 in each of which is inserted a metallic pin 97 with a projecting bottom 98 intended to be connected to the electrical circuit, as well as an upper part 99 protruding intended to be associated with the winding wire 13, for example by welding.
- the pin 97 Before its assembly to the carcass 12, the pin 97 has substantially the shape of a J, its lower part 98 being of higher transverse dimension to that of its upper part 99 (FIG. 25).
- Each pin 97 presents near its center, that is to say at the junction between its lower 98 and upper 99 parts, a step 100 forming a stop which, when the pin 97 is inserted into the hole 96 corresponding in the foot 95, is applied against a bearing surface 101 transverse formed in the hole 96.
- the upper part 99 In order to immobilize the pin 97 in the foot 95 to make it integral with the carcass 12, its upper part 99 is folded in a Z towards the front.
- the upper part 99 has, at a certain distance from the recess 100, a narrowing 102 which, when the upper part 99 is folded, forms the central branch of the Z and is housed in a complementary notch 103 made in the upper surface of the lower flange 91, and adjacent to the hole 96.
- the pin 97 is thus immobilized in translation in the direction elevation.
- the front branch 8 of the fixed frame 6 has a front face 104 and a rear face 105 opposite, connected by two lateral faces 106, 107.
- the hole crossing 94 of the core 93 of the carcass 12 also has a front face 108 and a rear face 109 opposite, connected by two lateral faces 110, 111.
- Each set J1, J2, J3, J4 is here predetermined by the chain of odds shorter directly connecting the junction surfaces of the fixed frame 6, the base 3 and of the carcass 12, starting from a terminal surface formed by a face 104, 105, 106, 107 of the front branch 8 delimiting said clearance, to result in the face 108, 109, 110, 111 of the hole 94 opposite, forming another surface terminal delimiting the same set J1, J2, J3, J4.
- the elevation dimension or height of the carcass 12, measured between the faces not facing the flanges, that is to say a face lower 112 of the lower flange 91 and an upper face 113 of the flange greater 92, is chosen less than the elevation dimension or height of the front leg 8, that is to say the distance separating the upper face 15 from the base 10 of the polarization surface 20.
- the foot 95 is pressed into the hole 66 at a predetermined depth, such as, on the one hand, the branch front 8 protrudes from the upper flange 92, the free end 20 of the front branch 8 protruding from the upper face 113 of the upper flange 92, and, on the other hand, the lower face 112 of lower flange 91 is spaced from upper face 15 of base 10 so that there is a clearance J5 between them (FIG. 2).
- the carcass 12 is rigidly mounted relative to the housing, while being mounted floating relative to the fixed frame 6, that is to say spaced of it at any point.
- the fixed frame 6 is thus preserved from stresses and deformations to which the carcass 12 is subjected, in particular during the mounting pins 97 on the aforementioned electrical circuit.
