Abstract
Description
Technical Field
[0001] This invention relates to the field of electronic components technology, specifically to a linkage radio frequency coaxial switch assembly. Background Technology
[0002] A radio frequency coaxial switch (relay) is an electrical control device that causes a predetermined step change in the controlled variable in the electrical output circuit when the input quantity changes to a specified value. It establishes an interactive relationship between the control system and the controlled system. Commonly used in automated control circuits, it is essentially an "automatic switch" that uses a small current to control a large current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching.
[0003] While there are many types and quantities of relays currently available, RF switches typically utilize a push rod to actuate a movable conductive plate, making contact with a pair of connector terminals and connecting the RF signal path between the two connector terminals. A common design involves a pair of electromagnets causing a seesaw-shaped soft magnet to swing, thereby actuating the push rod to activate the switch.
[0004] However, existing RF switches are single, controlling the circuit to turn on or off with a single RF switch. When multiple circuits need to be controlled, multiple RF switches are required, which is very costly and a heavy burden for users. Using multiple RF switches also makes control more complicated and increases the difficulty of use. Summary of the Invention
[0005] The purpose of this invention is to provide a linkage radio frequency coaxial switch assembly to solve the problems in the prior art where existing radio frequency switches are single and control the conduction or disconnection of a circuit through a single radio frequency switch. When multiple circuits need to be controlled, multiple radio frequency switches are required, which is very costly and a heavy burden for users. Furthermore, the control of multiple radio frequency switches is also cumbersome, increasing the difficulty for customers to use.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a linkage radio frequency coaxial switch assembly, comprising a plurality of radio frequency switches, wherein a tray is provided inside the linkage radio frequency coaxial switch assembly, the tray is connected to a motor, the plurality of radio frequency switches are arranged sequentially below the tray, and the motor drives the tray to drive the plurality of radio frequency switches to switch in linkage.
[0007] Preferably, there are 16 radio frequency switches.
[0008] Preferably, the tray is connected to the motor via a rotating shaft, and a set of reduction gears is provided on the rotating shaft.
[0009] Preferably, a permanent magnet is arranged above the armature assembly of each radio frequency switch, and the permanent magnets are arranged in the tray in sequence.
[0010] Preferably, the armature assembly comprises a soft magnetic armature, an armature spring, and an armature rotating shaft, the armature rotating shaft is arranged in the middle of the soft magnetic armature, the middle of the soft magnetic armature is provided with a downward boss, and the armature spring is arranged below the boss.
[0011] Preferably, a plurality of pressure sheets are arranged below the tray, and the number of the pressure sheets is the same as that of the radio frequency coaxial switches.
[0012] Preferably, pressure springs are embedded in the two sides below the tray, and the pressure springs are provided with pressure blocks below, and the number of the pressure blocks is equal to the number of channels required to be switched by the radio frequency coaxial switches.
[0013] Preferably, the radio frequency switch further comprises a left push rod assembly, a right push rod assembly, and a cavity, the left push rod assembly and the right push rod assembly each comprise an upper push rod, a lower push rod, a counterforce spring, an inner conductor sheet, and a flexible limiting belt, the counterforce spring is arranged at the bottom of the lower push rod, the flexible limiting belt is bonded to the inner conductor sheet, and the inner conductor sheet is arranged below the upper push rod and in the cavity.
[0014] Preferably, the cavity is composed of a base and a cover plate and forms a closed space.
[0015] Preferably, the radio frequency switch further comprises a first coaxial connector, a second coaxial connector, and a third coaxial connector, the first coaxial connector, the second coaxial connector, and the third coaxial connector each comprise a conductor core, an insulating layer, and a shell, and the conductor core is arranged in the cavity.
[0016] Compared with the prior art, the radio frequency coaxial switch assembly has the following beneficial effects:
[0017] 1. When the motor 80 rotates clockwise and drives the tray 41 to rotate clockwise through the gear assembly 81 and the rotating shaft 82, the right ends of all the permanent magnets 40 approach and attract the right ends of the armatures 31, so that all the armatures 40 rotate counterclockwise, and the left ends of the armature springs 32 push the push rod assemblies 50a downward, until the corresponding left inner conductor sheets 53 are connected to the coaxial connectors 10 and 10a at the same time, so that the coaxial connectors 10 and 10a are connected in conduction. At the same time, the lower push rod 54 of the right push rod assembly 50b is pushed upward by the counterforce spring 52, so that the corresponding right inner conductor sheet 53 is separated from the coaxial connectors 10 and 10b, and the channel 10-10b is disconnected. In the same way, the counterclockwise rotation of the motor 80 will drive all the permanent magnets 40 and the armature assemblies 30 to make all the radio frequency ports 10 and 10b of the switches communicate through the corresponding push rod assemblies, while 10 and 10a are disconnected.
[0018] 2. The technical solution of Example 2 is that when the motor 80 rotates counterclockwise and drives the tray 41 to rotate counterclockwise through the gear assembly 81 and the rotating shaft 82, the left end of the pressure plate 42 pushes the push rod assembly 50a downward until the corresponding left inner conductor plate 53 connects the coaxial connectors 10 and 10a at the same time, so that it is conducted. At the same time, the lower push rod 54 of the right push rod assembly 50b is pushed upward by the counterforce spring 52, so that the corresponding right inner conductor plate 53 is separated from the coaxial connectors 10 and 10b, so that the channel 10-10b is disconnected. In this way, the clockwise rotation of the motor 80 will link all the pressure plates 42, and through the corresponding push rod assemblies, all the radio frequency ports 10 and 10b of the switches are connected, while 10 and 10a are disconnected.
[0019] 3. The technical solution of Example 3 is that when the motor 80 rotates counterclockwise and drives the tray 41 to rotate counterclockwise through the gear assembly 81 and the rotating shaft 82, the tray 41 pushes the left end of the pressure block 44 downward through the pressure spring 43, and the push rod assembly 50a is pushed downward until the corresponding left inner conductor plate 53 connects the coaxial connectors 10 and 10a at the same time, so that it is conducted. At the same time, the lower push rod 54 of the right push rod assembly 50b is pushed upward by the counterforce spring 52, so that the corresponding right inner conductor plate 53 is separated from the coaxial connectors 10 and 10b, so that the channel 10-10b is disconnected. In this way, the clockwise rotation of the motor 80 will link all the pressure springs 43 and pressure blocks 44, and through the corresponding push rod assemblies, all the radio frequency ports 10 and 10b of the switches are connected, while 10 and 10a are disconnected.
[0020] The radio frequency switch of the utility model, through the motor 80 control S1 to S16 total 16 radio frequency switch's linkage, need not use many radio frequency switches, has reduced the use cost of customer, convenient operation at the same time. BRIEF DESCRIPTION OF DRAWINGS
