Definitions

  • This invention relates to a self-terminating coaxial switch.
  • a coaxial microwave switch for use in a multi-position switching device with a termination resistance provided at each position for each coaxial terminal such that any terminal not being used for transmission of a-signal ends in a termination resistance.
  • This termination resistance is typically a 50 ohm resistor.
  • Various means of providing switches with such features have been shown, generally using thin, narrow conductor reeds. For example, a conductor reed may be selectively placed in contact between the common coaxial terminal of a multi-position switching device and a selected one of many coaxial terminals, providing a microwave signal path between the common terminal and the selected terminal.
  • a termination reed may be selectively placed in contact between the selected coaxial terminal and a termination resistance.
  • any signal path not being used for transmission may be provided with a termination resistor.
  • Such reeds must be made to operate in alternating engagement, which generally requires the use of rocker arms and solenoids. This is because, for a selected coaxial terminal, either the common coaxial terminal or the termination resistor is connected to the coaxial terminal at any given time.
  • Such switches require many moving parts and careful assembly. For example, conductor reeds for the signal path and for the termination resistor are required, as well as springs for each such reed. These reeds may be placed in a "dog-leg" arrangement, where the signal path reed is positioned adjacent to, but at an angle from, the termination resistor reed, both reeds terminating at one end at a common coaxial terminal.
  • the number of coaxial terminals is limited by the geometry required to accommodate the switches within a housing.
  • An object of the present invention is to provide a more compact, self-terminating, coaxial switch for use in a multi-position coaxial microwave switching device, with fewer moving parts. This results in a more economical switch, with increased reliability, and allows for more coaxial terminals in a multi-position coaxial microwave switching device of a given size.
  • a self-terminating coaxial microwave switch having a first terminal that is selectively connectable to a second terminal by a reed conductor and that has a termination resistor, the improvement wherein:
  • Preferred embodiments of the present invention provide a self-terminating microwave switch that is a less complicated mechanism that those currently in use, for added, reliability, compact dimension, and easier production.
  • the termination resistor is allowed to physically move into and out of contact with a coaxial connector.
  • a conductor reed is provided for connecting a selected coaxial terminal to the common coaxial terminal.
  • One end of the termination resistor and one end of the conductor reed physically contact the same coaxial. terminal. In this way, termination resistor reeds are not required, resulting in a simpler, more compact switch.
  • a rocker arm may be provided, where one end of the rocker arm moves the termination resistor and the other end moves the conductor reed, the rocker arm being actuated by either a solenoid or by a magnetic latch.
  • springs are provided at both ends of the termination resistor such that an "at-rest” or “power-off” position is established and so that the resistor does not tend to stay at either end of its travel when the rocker arm is moved.
  • the invention provides a multi-position microwave switching device having a common coaxial terminal and a plurality of peripheral coaxial terminals wherein each position of the multi-position switching device includes a switch in accordance with said one aspect of the present invention.
  • a multi-position microwave switching device 10 is shown in Figure 1, at an angle showing the underside of the switch with the central coaxial terminal 20 and the peripheral coaxial terminals 30.
  • a single self-terminating microwave switch 40 is shown in further detail in Figure 3.
  • Figure 2 is a view of the base of the multi-position switching device 10 along section line 2, wherein the base 50 is shown with the cavity 60 having a central portion and radial portions extending therefrom.
  • the base 50 is also shown the central coaxial terminal 20 and the peripheral coaxial terminals 30.
  • the conductor reeds 70 are shown in the radial portions of the cavity 60, where it can be seen that the conductor reeds connect the central coaxial terminal 20 with any one of the peripheral coaxial terminals 30.
  • the termination resistors 80 located above the peripheral coaxial terminals 30.
  • Each peripheral coaxial terminal has an associated conductor reed and termination resistor.
  • the conductor reed and termination resistor corresponding to a peripheral coaxial terminal both contact the same terminal. It can also be seen that the conductor reeds have a pointed end 73 adjacent the central coaxial terminal 20 and an opposite end 78 shaped to substantially conform to the shape of the termination resistors 80.
  • a self-terminating microwave switch is shown in further detail in Figure 3.
  • the central coaxial terminal 20 and a peripheral coaxial terminal 30 are shown extending through the body housing 50.
  • a conductor reed 70 is shown positioned above the coaxial terminals, with the termination resistor 80 in contact with the peripheral coaxial terminal 30.
  • a rocker arm 90 performs the function of alternately moving the termination resistor 80 and conductor reed 70 into contact with the same peripheral coaxial terminal.
  • a solenoid 100 is positioned above one end of the rocker arm 90, with a plunger 110 forcing down the rocker arm 90 whenever the solenoid 100 is actuated.
  • FIG. 3 Also shown in Figure 3 are the relative shapes and locations of the conductor reed 70, the termination resistor 80, the central coaxial terminal 20, and the peripheral coaxial terminal 30.
  • the flat, narrow conductor reed 70 which is movable toward and away from the common plane containing the surface of the central coaxial terminal 20 and peripheral coaxial terminal 30, is shown moved away from the coaxial terminals.
  • the termination resistor 80 which is movable toward and away from the peripheral coaxial terminal 30, is shown contacting the terminal.
  • the end of the conductor reed 70 and the termination resistor 80 come into contact with different portions of the peripheral coaxial terminal 30.
  • the convex, semi-circular shape of one end 78 of the conductor reed 70 which contacts the peripheral coaxial connector 30, and the pointed end 73 of the opposite end, both illustrated earlier in Figure 2.
  • FIG. 4 illustrates an alternative embodiment of the present invention.
  • a central coaxial terminal 20 and peripheral coaxial terminal 30 are again shown extending through a body portion 50.
  • a conductor reed 70 is allowed to complete a microwave signal path between the central coaxial terminal 20 and peripheral coaxial terminal 30, with a termination resistor 80 allowed to contact the peripheral coaxial terminal 30.
  • the conductor reed and termination resistor physically contact the same peripheral coaxial terminal.
  • a rocker arm 170 is used to act upon a conductor reed shaft 130 in compressing the conductor reed spring 120, thereby forcing the conductor reed 70 into contact with the coaxial terminals.
  • a solenoid is not used. Rather, a magnetic latch is used to act upon the rocker arm 170.
  • the magnetic latch includes two coils 180, 190 that have windings that are wound in opposite directions so that their respective magnetic forces act in opposite directions.
  • a permanent magnet 200 is positioned between the coils 180, 190, a magnet cover plate 210 constructed of a magnetically susceptible material being placed above the coils 180, 190 and the permanent magnet 200.
  • the rocker arm 170 is allowed to move between a first position and a second position. When the rocker arm 170 is in either position, a magnetic path is completed, comprising the permanent magnet 200, the magnet cover plate 210, one of the coils 180, 190, and a portion of the rocker arm 170. In this way, the rocker arm 170 is held or latched in position by the permanent magnet 200.
  • a cap 220 is located at the end of the termination resistor adjacent to the rocker arm 170, with a termination spring 140 located underneath the cap 220. In this way, when the conductor spring 120 is compressed, the termination spring 140 is allowed to expand, thus lifting the termination resistor 80 out of contact with the peripheral coaxial terminal 30.
