Description

Technical Field

[0001] The invention relates to the technical field of electronic parts, in particular to a linked radio frequency coaxial switch component. Background Art

[0002] The RF coaxial switch (relay) is an electrical control device. It is an electrical appliance that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity reaches the specified requirements. It has an interactive relationship between the control system and the controlled system. It is usually used in automated control circuits. It is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit.

[0003] Although there are many types and quantities of relays at present, usually, the RF switch uses a push rod to push the movable conductive piece to contact a pair of connector terminals and connect the RF signal path between the two connector terminals. A common design is to make a seesaw-type soft magnet swing under the action of a pair of electromagnets to push the switch action of the push rod.

[0004] However, the existing RF switch is single, and the conduction or disconnection of the circuit controlled by one RF switch is controlled. When multiple circuits need to be controlled, multiple RF switches need to be used, which is very expensive and a great burden for users. If multiple RF switches are used, the control is also cumbersome, which increases the difficulty of use. Summary of the invention

[0005] The object of the present invention is to provide a linked RF coaxial switch assembly to solve the problem that the existing RF switch in the above-mentioned background technology is a single one, and the conduction or disconnection of the circuit controlled by one RF switch, when it is necessary to control multiple circuits, multiple RF switches need to be used, the cost is very high, and it is a great burden for users. If multiple RF switches are used, the control is also cumbersome, which increases the difficulty of customer use.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a linked RF coaxial switch assembly, comprising a plurality of RF switches, wherein a tray is arranged in the linked RF coaxial switch assembly, the tray is connected to a motor, a plurality of RF switches are arranged in sequence below the tray, and the motor drives the tray to drive the plurality of RF switches to switch in a linked manner.

[0007] Preferably, the number of the radio frequency switches is 16.

[0008] Preferably, the tray is connected to the motor via a rotating shaft, and a group of reduction gear assemblies are provided on the rotating shaft.

[0010] Preferably, the armature assembly includes a soft magnetic armature, an armature spring piece and an armature shaft, the armature shaft is arranged in the middle of the soft magnetic armature, a downward boss is arranged in the middle of the soft magnetic armature, and the armature spring piece is arranged below the boss.

[0011] Preferably, a plurality of pressure plates are provided below the tray, and the number of the pressure plates is the same as the number of the RF coaxial switches.

[0012] Preferably, pressure springs are embedded on both sides of the bottom of the tray, and pressure blocks are arranged below the pressure springs. The number of the pressure blocks is equal to the number of channels that the radio frequency coaxial switch needs to switch.

[0013] Preferably, the RF switch also includes a left push rod assembly, a right push rod assembly and a cavity, the left push rod assembly and the right push rod assembly respectively include an upper push rod, a lower push rod reaction spring, an inner conductor sheet and a flexible limiting band, the reaction spring is arranged at the bottom of the lower push rod, the flexible limiting band is bonded to the inner conductor sheet, and the inner conductor sheet is arranged below the upper push rod and located in the cavity.

[0014] Preferably, the cavity is composed of a base and a cover plate to form a closed space.

[0015] Preferably, the radio frequency switch further comprises a first coaxial connector, a second coaxial connector and a third coaxial connector, wherein 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 top of the conductor core is located in the cavity.

[0016] Compared with the prior art, the beneficial effects of the present invention are: a linked radio frequency coaxial switch component:

[0017] 1. The technical solution of implementation 1 is: when the motor 80 rotates clockwise and drives the tray 41 to rotate clockwise correspondingly through the gear assembly 81 and the rotating shaft 82, the right ends of all permanent magnets 40 approach and attract the right end of the armature 31, so that all armatures 40 rotate counterclockwise, so that the left end of the armature spring 32 pushes the push rod assembly 50a downward to move downward until the corresponding left inner conductor sheet 53 is connected to the coaxial connectors 10 and 10a at the same time, so that they are turned on. At the same time, the lower push rod 54 of the right push rod assembly 50b is pushed upward by the reaction spring 52, so that the corresponding right inner conductor sheet 53 leaves the coaxial connectors 10 and 10b, so that the channel 10-10b is disconnected. By analogy, the counterclockwise rotation of the motor 80 will link all permanent magnets 40 and the armature assembly 30, and the RF ports 10 and 10b of all switches are connected through the corresponding push rod assembly, and 10 and 10a are disconnected at the same time.

[0018] 2. The technical solution of Example 2 is as follows: when the motor 80 rotates counterclockwise and drives the tray 41 to rotate counterclockwise accordingly 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 sheet 53 simultaneously connects the coaxial connectors 10 and 10a, making them conductive. At the same time, the lower push rod 54 of the right push rod assembly 50b is pushed upward by the reaction spring 52, so that the corresponding right inner conductor sheet 53 leaves the coaxial connectors 10 and 10b, and the channel 10-10b is disconnected. By analogy, the clockwise rotation of the motor 80 will link all the pressure plates 42, and the RF ports 10 and 10b of all switches are connected through the corresponding push rod assemblies, while 10 and 10a are disconnected.

[0019] 3. The technical solution of Example 3 is as follows: when the motor 80 rotates counterclockwise and drives the tray 41 to rotate counterclockwise accordingly through the gear assembly 81 and the rotating shaft 82, the tray 41 pushes the pressure block 44 at the left end downward through the pressure spring 43 to push the push rod assembly 50a downward until the corresponding left inner conductor sheet 53 is simultaneously connected to the coaxial connectors 10 and 10a, making them conductive. At the same time, the lower push rod 54 of the right push rod assembly 50b is pushed upward by the reaction spring 52, so that the corresponding right inner conductor sheet 53 leaves the coaxial connectors 10 and 10b, and the channel 10-10b is disconnected. By analogy, the clockwise rotation of the motor 80 will link all the pressure springs 43 and the pressure block 44, and connect the RF ports 10 and 10b of all switches through the corresponding push rod assembly, while 10 and 10a are disconnected.

[0020] The radio frequency switch of the present invention controls the linkage of a total of 16 radio frequency switches from S1 to S16 through a motor 80, and does not need to use multiple radio frequency switches, thereby reducing the use cost of customers and facilitating operation.
