Definitions

  • the present invention relates to a switching device for opening and closing at least one electrical line, in particular a high frequency switch adapted to operate with continuous signals, low, medium or high frequencies.
  • Switching devices are already known for opening and closing an electrical line in which a blade-shaped contact piece is supported by an actuator movable in translation between a position in which said contact piece is applied to two parts. contact terminals by closing the power line, and a position in which it is spaced from said contact terminals by opening the power line.
  • the contact piece is guided by rods along which it slides, to ensure proper application of said contact piece against the contact terminals.
  • the European patent EP 0 670 579 attempts to solve this problem by means of a switching device comprising an operating member comprising an axially displaceable contact piece, and two parallel flexible blades each having a central portion secured to the actuating 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 operating member.
  • the patent EP-A-0618634 discloses a switching device according to the preamble of claim 1.
  • the present invention aims to meet all or part of the aforementioned needs.
  • the term "ability of the region secured to the actuating element or the actuating member to flex relative to adjacent regions" means the ability of this region to flex substantially independently of any bending experienced by adjacent regions. This gives a relative mobility of the latter relative to the adjacent regions, so as to guide the actuating element or the operating member in a substantially rectilinear translation movement.
  • the flexible holding member comprises a flexible return blade integral with an insulating pusher of an actuating member
  • this flexible return blade can be unique, unlike the device described in the European patent. EP 0 670 579 mentioned above, which comprises two parallel flexible blades.
  • the number of parts can be reduced and the device can be more economical and easier to assemble.
  • the height of the insulating pusher can be further reduced.
  • the invention is thus particularly suitable for devices of relatively small dimensions.
  • the holding element comprises at least one flexible blade provided with a preferably also flexible tongue cut in the blade.
  • the tongue can thus maintain, during a displacement of the actuating element or the actuating member, a position substantially perpendicular to the direction of movement.
  • the blade may have a substantially elongate shape and the region of the blade integral with a fixed part of the device and the aforementioned tongue may 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 situated in a non-central region of the holding element.
  • the aforementioned tongue may have a longitudinal axis and be connected to the rest of the blade at one 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 comprises a flexible return blade integral with an insulating pusher of an operating member and the device may comprise an electrically conductive closure plate provided with 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 may be substantially flat in the rest position.
  • the flexible return blade is adapted to exert a sufficient elastic return force so that, in the absence of a drive control of the element of actuation, the contact piece bears against the closure plate.
  • the flexible return blade is configured so that, in the absence of drive control of the actuating element, the contact piece is in an intermediate position, between the position of closing and a bearing position against the closure plate.
  • the flexible return blade is configured so that, in the absence of drive control of the actuating element, the contact piece bears against the corresponding contact terminals, that is to say in the closed position.
  • the flexible return blade is adapted to be directly attached to the actuating element, which further reduces the number of parts.
  • the presence of the above-mentioned flexible return blade has the advantage, when an actuating member is attached thereto, that any difference in axial displacement between the operating member and the element actuation which acts on this return blade can be compensated by a deformation of the flexible return blade.
  • the flexible return blade and the actuating element can cooperate by a rigid or non-rigid type connection.
  • the flexible return blade may comprise a tongue to which is fixed the actuating element, in addition to the tongue to which is fixed the operating member.
  • the actuating element is able to act on the operating member via a flexible control blade, separate from said return blade, this blade control may include a tongue adapted to bear against the pusher of the operating member.
  • the interposition of a flexible control blade between the actuating element and the actuating member has the advantage that a possible axial displacement difference between the actuating element and the operating member can be compensated by a deformation of the flexible control blade.
  • the actuating element comprises two upper and lower axial ends, the upper end at least being connected to a flexible holding element mentioned above.
  • the actuating element can no longer be guided by sliding on bearings, but be suspended from one or more flexible holding elements, which makes it possible to avoid any friction of the actuating element on the bearings. fixed parts of the device and therefore the appearance of dust that can affect the operation thereof.
  • the lower end of the actuating element is also connected to a flexible holding element.
  • the device may comprise a flexible control blade capable of acting simultaneously or alternately on said at least two actuators.
  • the aforesaid control blade may serve as a return blade for the two operating members, having two parts located on either side of the attachment portions of the control blade to fixed parts of the device, each of the parts being integral with an operating member, and the actuating element is able to act on one of said two parts of the blade so as to drive one of the two operating members to the open position and the other to the closed position.
  • control blade comprises two parts located on either side of portions for fixing the control blade to fixed parts of the device, each of said parts of the blade being able to act on a corresponding actuating member, the actuating element being fixed to the control blade in one of said two parts and the actuating members are each respectively secured to a return blade separate from the control blade.
  • the device comprises a flexible holding element provided with a plurality of blades each allowing the attachment of an operating member or an actuating element, the element of maintenance having in particular a geometry leaving it invariant by a rotation of 2 ⁇ ⁇ not , n being an integer, equal to 6 for example, about an axis of rotation perpendicular to the plane of the blades.
  • the plurality of blades may be replaced by attachment portions of the actuating member or actuating member each connected to the remainder of the holding member by a plurality of material bridges disposed on its periphery.
  • These elements include an actuator 1, two contact terminals 2 and 3, a closure plate 4 of a conductive body and a flexible return plate 5.
  • the operating member 1 comprises a contact piece 6 in the form of a metal blade, substantially rectangular, electrically conductive.
  • This contact piece 6 is attached to a pusher 7 electrically insulating.
  • the pusher 7 and the contact piece 6 are assembled by a mortise and tenon-type connection, as described in FIG. EP 0 670 579 .
  • the contact piece 6 is able to be applied simultaneously to the two contact terminals 2 and 3, in the closed position.

  • the flexible return blade 5 comprises a tongue 12 engaged in a groove 13 of the pusher 7 by being retained by a split ring 14.
  • the pusher 7 has a cross-sectional shape substantially rectangular and the tongue 12 has a correspondingly shaped orifice, so as to provide an anti-rotation connection between the pusher 7 and the blade 5.
  • the tongue 12 is formed within the blade 5 and connects to the remainder of this blade 5 in a region 15 adjacent to a free end of the blade 5, opposite to the connecting region 9.
  • the tongue 12 can perform a bending movement with respect to the rest of the blade 5, while the latter can perform a bending movement with respect to the studs 11.
  • This combination of bending movements ensures a substantially rectilinear displacement along the axis X of the operating member 1.
  • the blade 5 thus allows a reliable and precise positioning of the operating member in a plane parallel to the closure plate 4, which substantially reduces the risk of contact of the pusher 7 with the wall of the orifice 10.
  • the return blade 5 is prestressed.
  • the blade 5 permanently exerts on the pusher 7 a restoring force directed along the X axis, upwards, so that the contact piece 6 is, in the open position, bearing against the closing plate 4.
  • the pusher 7 is driven in displacement by means of an actuating element 20, represented partially on the figure 2 , at the lower end of which is fixed a flexible control blade 21, better visible on the Figures 3 and 4 .

  • the actuating element 20 is able to drive the operating member 1 to an open position in which the contact piece 6 bears against the closure plate 4, as illustrated in FIG. figure 2 towards a closed position of the electrical line, by pressing the tongue 22 on the pusher 7, as illustrated in FIG. figure 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 actuating element 20 having an axial displacement that is slightly too large compared to that of the operating member 1, which ensures an optimum contact between the contact terminals 2 and 3 and the contact piece 6.
  • the blade 5 with the exception of the recess made around the tongue 12, and the fixing holes on the studs 11, has only solid parts.
  • the blade 5 may have an additional opening configured to make it more flexible.

  • connection between the actuating element 20 and the return blade 5 is non-rigid, essentially ensuring the drive in vertical displacement of the blade 5.
  • the actuating element 20 and the blade 5 can also be configured to be connected by a ball joint, obtained for example by the presence of a groove 40 which allows not only the aforementioned clearance 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 than the thickness of the blade 5.
