Definitions
- the present invention relates to a switching device for opening and close at least one power line, in particular a high frequency switch capable of work equally well with continuous, low, medium or high frequency signals.
- the contact part is guided by rods along which it slides, in order to ensure proper application of said piece of contact against contact terminals.
- European patent EP 0 670 579 attempts to solve this problem by means of a switching device comprising an operating member comprising a piece of axially displaceable contact, and two parallel flexible blades each having a central part secured to the operating member and two ends each housed in a cradle of a fixed support.
- This switching device is satisfactory insofar as it eliminates friction at the level of the operating member.
- the object of the present invention is to meet all or part of the needs supra.
- suitableability of the region integral with the actuating element or of the actuator to flex relative to adjacent regions the ability of this region to flex substantially independently of the possible bending undergone by adjacent regions. We thus obtain a relative mobility of the latter with respect to adjacent regions so as to guide the actuating member or the member maneuver in a movement substantially in rectilinear translation.
- the flexible holding element comprises a blade flexible return integral with an insulating plunger of an operating member
- this blade flexible recall can be unique, unlike the device described in the European patent EP 0 670 579 cited above, which comprises two parallel flexible blades.
- the number of parts can thus be reduced and the device can be more economical and easier to assemble.
- the height of the insulating plunger can also be reduced.
- the invention is thus particularly suitable for devices for relatively small dimensions.
- the holding element has at least one flexible blade preferably also provided with a tongue flexible cut in the blade.
- the combination of a movement in bending blade, on the one hand, and a bending movement of the tongue, on the other hand, allows to obtain a displacement substantially in rectilinear translation of the element of actuation or of the operating member.
- the tongue can thus keep, during a displacement of the element actuating or operating member, a position substantially perpendicular to the direction of travel.
- the blade can have a shape that is substantially elongated and the region of the blade secured to a fixed part of the device and the tongue above can be located at opposite longitudinal ends of the blade. So the blade can be secured to a fixed part of the device only at one end, which increases the possibilities of fixing the blade on a fixed part of the device, for example on the frame thereof.
- the region of the holding element integral with the actuating element or the operating member is advantageously located in a non-central region of the holding member.
- the aforementioned tongue may have a longitudinal axis and be connected to the rest of the blade at a single longitudinal end.
- the aforementioned tongue advantageously connects to the rest of the blade in a region thereof adjacent to a free end of the blade.
- the flexible holding element may include a flexible return blade secured to a pusher insulating an operating member and the device may include an electrically conductive closure plate provided an orifice allowing the passage of the pusher, said orifice advantageously having a section chosen so as to allow passage and axial displacement of the pusher without friction.
- the holding element can be substantially plane in the rest position.
- the flexible return blade is able to exert a sufficient elastic restoring force so that, in the absence of a drive command of the actuating element, the contact piece comes resting against the closing plate.
- the flexible return blade is configured so that, in the absence of a drive command for the actuating element, the contact is in an intermediate position, between the closed position and a support position against the closing plate.
- the flexible return blade is configured so that that, in the absence of a drive command for the actuating element, the part contact bears against the corresponding contact terminals, that is to say in closed position.
- the flexible return blade is capable of directly joining the actuating element, which makes it possible to reduce still the number of pieces.
- the presence of the aforementioned flexible return blade has the advantage, when an operating member is attached to it, that a possible difference axial displacement between the operating member and the actuating element which acts on this return blade can be compensated by a deformation of the return blade flexible.
- the flexible return blade and the actuating element can cooperate by a rigid or non-rigid type of connection.
- the flexible return blade may have a tongue to which is attached the actuating element, in addition to the tongue to which the operating member is fixed.
- the element actuator is able to act on the operating member by means of a blade flexible control, distinct from said return blade, this control blade being able to include a tongue capable of coming to bear against the pusher of the operating member.
- the interposition of a flexible control blade between the element actuation and the operating member has the aforementioned advantage that a possible difference in axial travel between the actuating element and the operating member can be compensated by deformation of the flexible control blade.
- the actuating element has two upper and lower axial ends, the upper end at least being connected to a said flexible holding element.
- the actuating element can no longer be guided by sliding on bearings, but be suspended from one or more flexible retaining elements, which avoids possible friction of the actuating element on fixed parts of the device and therefore the appearance of dust which can affect the functioning of this one.
- the lower end of the actuating element is also connected to a flexible holding element.
- the device comprises at least two operating members for two power lines
- this can include a flexible control blade capable of acting simultaneously or alternatively on said at least two actuators.
- the aforementioned operating blade can serve as a reminder blade for both operating devices, having two parts located on either side of portions of fixing of the control blade to fixed parts of the device, each part being integral with an operating member, and the actuating element is capable of acting on one of said two parts of the blade so as to drive one of the two operating members towards the open position and the other towards the closed position.
- control blade has two parts located on the side and other fixing portions of the control blade to fixed parts of the device, each of said parts of the blade being capable of acting on an operating member corresponding, the actuating element being fixed to the control blade in one of said two parts and the operating members are respectively each secured a return blade separate from the control blade.
- the device comprises a flexible holding element provided with a plurality of blades each allowing the fixing an operating member or an actuating element, the holding element having in particular a geometry leaving it invariant by a rotation of 2 ⁇ / n, n being an integer, equal to 6 for example, around an axis of rotation perpendicular to the plane of the blades.
- the plurality of blades can be replaced by fixing parts of the actuating element or the operating member each connected to the rest of the holding element by a plurality of material bridges arranged around its periphery.
- FIG. 1 shows certain elements of a device for switching to open and close a power line.
- an operating member 1 there is an operating member 1, two contact terminals 2 and 3, a closure plate 4 of a conductive body and a flexible return blade 5.
- the operating member 1 comprises a contact piece 6 which is under the shape of a metal blade, substantially rectangular, electrically conductive.
- This contact piece 6 is fixed to an electrically insulating pusher 7.
- the pusher 7 and the contact piece 6 are assembled by a tenon-mortise type bond with crushing material, as described in EP 0 670 579.
- the contact piece 6 is able to be applied simultaneously on the two contact terminals 2 and 3, in the closed position.
- Closing plate 4 which provides electromagnetic shielding from from the external environment, has an orifice 10 allowing passage and axial movement of the pusher 7 without friction, along an axis X, as can be seen in Figure 2 in particular.
- the flexible return blade 5 has a generally trapezoidal shape, when viewed from above. This blade 5 has a connecting region 9 located on the side of the large base of the trapezoid and fixed to two studs 11 mounted on the closure plate 4.
- the flexible return blade 5 has a tongue 12 engaged in a groove 13 of pusher 7 while being retained there by a split ring 14.
- the pusher 7 has a cross section of shape substantially rectangular and the tongue 12 has an orifice of corresponding shape, so as to ensure an anti-rotation connection between the pusher 7 and the blade 5.
- the tongue 12 is produced within the blade 5 and is connected to the rest of this blade 5 in a region 15 adjacent to a free end of the blade 5, opposite the region 9.
- the tongue 12 can perform a bending movement relative to the rest of the blade 5, while the latter can perform a bending movement relative to the studs 11.
- This combination of bending movements ensures displacement substantially straight along the axis X of the operating member 1.
- the blade 5 thus allows reliable and precise positioning of the maneuver in a plane parallel to the closure plate 4, which significantly decreases the risk of contact of the pusher 7 with the wall of the orifice 10.
- the return blade 5 is prestressed.
- the blade 5 exerts a permanent force on the pusher 7 return directed along the X axis, upwards, so that the contact part 6 is located, in the open position, pressing against the closing plate 4.
- the pusher 7 is driven in displacement by means an actuating element 20, partially shown in Figure 2, at the end bottom of which is fixed a flexible control blade 21, better visible in the figures 3 and 4.
- the flexible control blade 21 has a tongue 22 connecting to the rest of blade 21 in region 23 located at an end opposite region 24 of connection of the blade 21 to the actuating element 20.
- the actuating element 20 is adapted to drive the operating member 1 an open position in which the contact piece 6 is in abutment against the plate closure 4, as illustrated in FIG. 2, towards a position for closing the line electric, by pressing the tab 22 on the pusher 7, as illustrated in FIG. 4.
- the tongue 22 then takes a position substantially perpendicular to the axis X and exerts on the pusher 7 a thrust force substantially parallel to the axis X.
- the presence of the flexible control blade 21 makes it possible to use an element actuator 20 having a slightly too large axial clearance relative to that of the operating member 1, which ensures optimal contact between the contact terminals 2 and 3 and contact part 6.
- the blade 5 with the exception of the recess produced around the tongue 12, and fixing holes on the studs 11, has only parts full.
- the blade 5 may have an additional configured opening so as to make it more flexible.
- FIG. 7 shows a flexible return blade 5 'substantially similar to the return blade 5, but which differs from the blade 5 in that it has a second tab 25.
- This tongue 25 is produced within the return blade 5 'and is connected to a region thereof remote from the connecting region 9, like the flexible tongue 12.
- the actuating element 20 constitutes the movable part of an actuator of the type electromagnetic, being driven in displacement by a coil 29 fixed relative to the switching device, as illustrated very diagrammatically in FIG. 5, the member operating in the closed position.
- the coil 29 is connected to the rest of the switching device by means not shown.
- the electromagnetic actuator can be of the type polarized or not.
- the actuating element 20 is fixed, in its upper part 30 and in its lower part 31, respectively, to flexible retaining blades 32 and 33.
- These blades 32 and 33 each have an end integral with a fixed part 34 of the switching device, for example of a frame.
- these flexible blades 32 and 33 each have a tongue 36 and respectively 37, to which the ends of the actuating element 20.
- the actuating element 20 is thus kept in suspension by the two flexible blades 32 and 33 and does not rub against any fixed part of the device switching.
- the actuating element 20 can be directly attached to the return blade 5.
- the actuating element 20 has a lower groove 40 and the return blade 5 has an orifice 41 allowing to engage the blade 5 in the groove 40.
- the orifice 41 has a section chosen so as to allow play between the actuating element 20 and the blade 5 in the plane of the blade 5.
- connection between the actuating element 20 and the return blade 5 is non-rigid, essentially ensuring the vertical displacement drive of the blade 5.
- the actuating element 20 and the blade 5 can also be configured from so as to be connected by a ball joint, obtained for example by the presence of a groove 40 which allows not only the above play in the plane of the blade 5, but also an axial clearance between the blade 5 and the groove 40 which has a greater depth important than the thickness of the blade 5.
- connection between the element actuation 20 and the blade 5 is rigid.
- the lower retaining blade 33 is thus no longer necessary in this example of implementation.
- the blade of control acts on a single operating member.
- control blade acts on two actuators simultaneously or alternately.
- FIG. 10 shows a switching device comprising a control blade 50 comprising two parts 51 and 52 of generally shaped rectangular, located on either side of portions 53 for fixing the blade 50 on 55 fixed studs.
- the rectangular part 51 on the left, comprises a tongue 56 on which is fixed an operating member 57, this tongue 56 connecting by two returns 59 to the rest of the rectangular part 51.
- the actuating element 20 is fixed to this rectangular part 51 by through a rigid connection 58 by embedding in a groove of the element actuating.
- This rigid connection 58 can in particular be produced by means of a screwing, crimping or bonding, this list is not exhaustive.
- the second operating member 60 is fixed to the rectangular part 52, at right in Figures 10 and 11.
- the part 52 is devoid of tongue made in its breast.
- the region 52 may include a tongue with which is fixed the operating member 60.
- the actuating element 20 and the part 51 cooperate via a ball joint 58 ', in which case it is necessary to fix the lower part of the actuating element 20 to a flexible blade, as this is the case in Figure 8.
- the control blade 50 exerts, via of the tongue 56, a downward pushing force on the operating member 57 of so as to bring it into its closed position.
- the part 52 drives the operating member 60 upwards, in its position opening, pressing against the closing plate.
- a device which, with a single element actuation 20, to drive two operating members moving in opposite directions, so as to obtain alternative openings and closings of power lines.
- control blade 50 thus also serves as a blade reminder for operating devices 57 and 60.
- the operating members 57 and 60 are each connected to fixed parts of the device by means of a blade return 65 substantially similar to the return blade 5 previously described.
- This device comprises a control blade 50 ′ generally analogous to the control blade 50, but not integral with the operating members 57 and 60.
- the region 52 of the blade 50 ′ swings upwards so as to allow the operating member 60, under the effect of the restoring force exerted by the blade 65, to be driven upwards, in the open position.
- FIGS. 15 to 20 show such flexible elements, in accordance with different examples of implementation of the invention.
- the flexible elements include each six flexible blades 70 on each of which can be fixed an operating member ( Figures 16, 18, 19, 20) or an actuating element ( Figures 16, 17, 18, 19, 20).
- the flexible element of Figure 15 does not have a flexible blade, but parts 71 each connected to the rest of the flexible element by four bridges of material 72 in U shape arranged around a part 71.
- This part 71 can thus be axially movable relative to the rest of the flexible element to which it is connected.
- the aforementioned flexible elements have a symmetry of revolution, that is to say they have a geometry leaving the element invariant by a rotation of 2 ⁇ / 6 around an axis perpendicular to the plane of the blades.
- a switching device can be produced with two flexible elements superimposed above, one secured to actuating elements and comprising blades control 70 and the other secured to operating members and comprising blades reminder 70.
- the aforementioned flexible elements can be fixed to a fixed part of the device by means of studs engaging in openings 75 of the flexible elements.
- openings 75 can be six in number and are located on the periphery of the flexible element, requiring the presence of six studs, as illustrated in FIG. 15.
- the flexible element may have a single central opening 75 for fixing a single stud, as illustrated in figure 20.
- the flexible elements described in Figures 15 to 20 can have a number different from blades, less than or more than six.
