Definitions

  • the present invention is based on a coaxial switch, as known from DE 31 24 830 A1 and DE 31 22 780 A1.
  • at least one conductive connecting element is moved using one or more dielectric holding supports that slide in openings in a wall.
  • forces act on the dielectric holding supports, and the connecting element is brought into connection with two inner conductors of the coaxial lines by displacement.
  • the coil spring-loaded insulating elements create a counterforce that pushes the connecting element back into its initial position when the electrical connection is to be interrupted.
  • DE-OS 16 15 594 discloses a coaxial switch in which a connecting element and a holding support are moved via a single leaf spring.
  • the support bracket is passed through a wall of a cavity in which the connecting element is located.
  • the leaf spring is located outside the cavity.
  • DE 24 60 266 A1 discloses a device for selectively switching on one of two four-pole connections between two asymmetrical lines. There are two Inner conductor ends together between two outer conductor surfaces, which are each formed by a leaf spring and carry four poles, which can be alternately connected between the inner conductors.
  • the present invention has for its object to provide a coaxial switch of the type mentioned, which achieves high reliability. According to the invention, this object is achieved by the features specified in claim 1. Advantageous designs emerge from the subclaims.
  • connecting elements are mounted in a leaf spring arrangement. This results in designs with very little wear, which achieves high reliability.
  • a precise linear movement of the connecting element is achieved by a leaf spring arrangement.
  • no sliding guide is required for the support brackets, these can be moved in a housing bore without contact and smoothly.
  • the support posts usually made of a dielectric material, do not suffer wear and tear Any abrasion that could impair the properties of the coaxial switch is avoided.
  • the leaf spring arrangement is e.g. constructed from two spring membranes arranged one above the other, in which leaf springs have been produced by cuts. Two leaf springs of the two spring membranes are connected to each other to form a four-leaf spring straight guide.
  • the leaf springs in the spring membranes are dimensioned and arranged in such a way that a stable spring joint guide is created without transverse displacement.
  • the advantageous arrangement of the leaf springs results in a compact and lightweight switch.
  • the friction-free mounting of the inner conductor also allows a purely magnetic drive.
  • the measures mentioned achieve a very high reliability of the coaxial switch. This is particularly important for designs for space technology.
  • Figure 1 shows the principle of operation of a transfer switch with four connections 1, 2, 3, 4 and two switching positions item 1 and item 2.
  • item 1 the connections 1 with 3 and 4 with 2 and in item 2 the connections 1 with 4 and 2 with 3 each connected to each other.
  • Figure 2 shows the basic embodiment of a T-switch with four connections 1, 2, 3, 4 and three switch positions pos. 1, pos. 2 and pos. 3. The connections between the connections are shown in the drawings according to Fig. 1.
  • FIG. 3 shows a transfer switch 20 in a section through an axis 15.
  • 1 shows a coaxial high-frequency connection and 2 the elongated inner conductor, which ends in a cavity 3 in the housing.
  • the wall of the cavity 3 forms, together with a connecting element 4 (the longitudinal direction of which runs perpendicular to the plane of the drawing), a coaxial line which, depending on the switching position, forms a connection between the ends of the inner conductor 2 of two connections 1 (see FIG. 1, connections 1, 2 , 3, 4).
  • a further connecting element 4 is provided mirror-symmetrically to the axis 15. It is guided by means of a leaf spring arrangement (leaf spring straight guide) 7, 8, 9, 10 and dielectric holding supports 5, which are passed through a through opening 6 of a wall of the cavity 3 without contact and smoothly.
  • the leaf spring straight guide 7, 8, 9, 10 serves as a guide device for the holding support 5.
  • 7 and 9 show two spring membranes (see FIG. 4), which at their outer ends (at 34 in FIG. 4) by coupling pins 10 and at their free spring ends (at 31, 32, 33 in FIG. 4) by the dielectric holding supports 5 and permanent magnets 8.
  • the respective center of the two spring membranes 7, 9 is clamped in the switch center 17.
  • the drive for support brackets 5 consists of a rotor 12
  • 18 shows a bearing of the rotor 12, 16 an electrical connection.
  • FIG. 4 shows a spring membrane 30 (7, 9 in FIG. 3) of the transfer switch 20 (FIG. 3), which contains segments 36 and 37, which correspond to a leaf spring which is folded into itself.
  • the dielectric support brackets 5 and the permanent magnets 8 are fastened to the segment 36 via bores 31, 32, 33, the coupling pins 10 to bores 34.
  • the bore 38 serves to fasten the spring membrane 30 in the center of the switch 17.
  • the segments 36 and 37 can be understood as a series connection of two springs, the folding results in a sufficiently large spring travel with compact dimensions.
  • FIG. 5 shows a T switch 40 in an axial section.
  • 41 and 42 show two coaxial high-frequency connections, 43 and 44 are the extended inner conductors.
  • Two spring membranes 48 and 49 are attached in this switch design in the border 51 of the switch. These contain leaf springs (see FIG. 6) which serve as guide devices 48, 49, 50 for dielectric holding supports 46, 47.
  • leaf springs which serve as guide devices 48, 49, 50 for dielectric holding supports 46, 47.
  • a support bracket 46a which carries an invisible connecting element, is also assigned a leaf spring arrangement with leaf springs in the different diaphragm springs 48, 49.
  • the dielectric holding supports 46, 47 move a connecting element 45 for contacting the two inner conductors 43 and 44.
  • the holding supports 46, 47 are deflected by a drive, corresponding to that of the coaxial switch 20 described with reference to FIG. 3, which contains a rotor 53.
  • a permanent magnet 52 of the rotor 53 moves a permanent magnet 50 of the guide device 48, 49, 50.
  • the rotor 53 contains permanent magnets 52 with different polarities, so that the holding supports 46, 47 can be moved in opposite directions.
  • the support brackets 46, 47 are also here contactless and therefore smooth Feed-through openings 54, 55 are passed through a wall.
  • FIG. 6 shows a leaf spring 60 of a spring membrane (48, 49) of the T switch 40 (see FIG. 5).
  • An inner segment 65 and an outer segment 66 are produced in the spring membrane (48, 49) by means of two arcuate or U-shaped cuts 63, 64, which together correspond to a leaf spring folded into itself. These two segments 65, 66 are also dimensioned such that their transverse displacements compensate one another when deflected.
  • the dielectric holding supports 46, 47 and the permanent magnet 50 (FIG. 5) are fastened to the bores 61, 62.
  • Two leaf springs 60 made of different spring membranes 48, 49 of the T switch 40 are each arranged one above the other and together form a four-leaf spring straight guide. In this embodiment, a plurality of leaf springs 60 can be distributed as desired in a spring membrane (48, 49).
  • the cuts 63, 64 can also be made in other shapes, e.g. shown in Fig. 4.
