A gang radio frequency coaxial switch assembly with stop feedback

Abstract

This utility model discloses a linkage RF coaxial switch assembly with stop feedback, comprising several RF coaxial switches, a motor, a tray, and a printed circuit board. The tray is connected to the motor. An isolation groove is formed on the printed circuit board, with a light-emitting unit on one side and a photosensitive unit on the other. A baffle is fixed on the tray, and the RF coaxial switches are positioned below the tray. This linkage RF coaxial switch assembly with stop feedback allows the baffle to block the photosensitive unit when the RF switch is turned on, preventing the photosensitive unit from conducting. This feedback can be sent to the motor drive circuit, stopping the motor's rotation after the switch completes switching, enabling precise motor stopping, reducing damage to the RF switch, and extending its service life.

Description

Technical Field

[0001] This utility model relates to the field of electronic components technology, specifically to a linkage radio frequency coaxial switch assembly with stop feedback. 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 available today, radio frequency (RF) switches typically utilize a push rod to actuate a movable conductive plate, which contacts a pair of connector terminals, thus connecting the RF signal path between the two connector terminals. A common design involves a seesaw-shaped soft magnet oscillating under the action of a pair of electromagnets to actuate the push rod.

[0004] However, existing motor-controlled RF switches lack a feedback mechanism, which can lead to inaccurate control. During operation, even if the switch is engaged, the motor may continue to operate, which can easily damage the RF switch and affect its lifespan. Utility Model Content

[0005] The purpose of this invention is to provide a linkage radio frequency coaxial switch assembly with stop feedback, in order to solve the problem in the prior art where the existing motor-controlled radio frequency switch lacks a feedback mechanism, leading to inaccurate control. During operation, even if the switch is connected, the motor will still work, which can easily damage the radio frequency switch and affect its service life.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a linkage radio frequency coaxial switch assembly with stop feedback, comprising a plurality of radio frequency coaxial switches, a motor, a tray, and a printed circuit board, characterized in that the tray is connected to the motor, the printed circuit board has an isolation groove, a light-emitting unit is provided on one side of the isolation groove and a photosensitive unit is provided on the other side, a baffle is fixed on the tray, and the radio frequency coaxial switches are disposed below the tray.

[0007] Preferably, the radio frequency coaxial switches are arranged sequentially below the tray, and the tray is driven by a motor to drive several radio frequency switches to switch in a coordinated manner.

[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, the radio frequency coaxial switch includes a pressure plate, a left push rod assembly, a right push rod assembly, a first coaxial connector, a second coaxial connector, a third coaxial connector, a base, a cover plate, and a cavity. The left push rod assembly and the right push rod assembly are located in the cavity and extend above the cover plate. The upper parts of the first coaxial connector, the second coaxial connector, and the third coaxial connector are located in the cavity.

[0010] Preferably, the radio frequency coaxial switch further includes a left push rod assembly and a right push rod assembly. The left push rod assembly and the right push rod assembly each include an upper push rod, a lower push rod reaction spring, an inner conductor sheet, and a flexible limiting band. The reaction spring is disposed at the bottom of the lower push rod, and the flexible limiting band is adhered to the inner conductor sheet. The inner conductor sheet is disposed below the upper push rod and located within the cavity.

[0011] Preferably, the cavity consists of a base and a cover plate, forming a closed space.

[0012] Preferably, the first coaxial connector, the second coaxial connector, and the third coaxial connector each include a conductor core, an insulating layer, and a housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are: a linkage radio frequency coaxial switch assembly with stop feedback:

[0014] The system incorporates a mechanical linkage structure and a stop feedback component. The tray is connected to a gear assembly and a motor via a tray shaft. The motor can rotate clockwise or counterclockwise, and through the gear assembly and shaft, it applies torque to all pressure plates, driving the push rod assembly to perform the linked switching. The stop component includes a baffle, a light-emitting unit, a photosensitive unit, an isolation slot, and a printed circuit board. The baffle is fixed to the tray and linked to it. The light-emitting unit and photosensitive unit are mounted on the circuit board, facing each other. The isolation slot is located in the circuit board between the light-emitting unit and the photosensitive unit, below the baffle, allowing the baffle to move freely up and down between them. When the baffle moves between the light-emitting unit and the photosensitive unit, blocking the photosensitive unit from receiving light, the photosensitive unit is not conductive. When the baffle moves away from the light-emitting unit and the photosensitive unit, the photosensitive unit can receive light and is in a conductive state. The conductive and non-conductive states of the photosensitive unit are fed back to the motor drive circuit, causing the motor to stop rotating after the switch is completed.

[0015] The radio frequency switch of this invention, when the radio frequency switch is turned on, the baffle blocks the photosensitive unit, preventing the photosensitive unit from conducting. This can be fed back to the motor drive circuit so that the motor stops rotating after the switch is completed, enabling the motor to stop precisely, reducing damage to the radio frequency switch, and extending the service life of the radio frequency switch.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please refer to Figures 1, 2 and 3. This utility model provides a technical solution: as shown in the figures, the utility model disclosed herein consists of multiple single-pole double-throw radio frequency coaxial switches and has stop feedback to stop the operation after the switch has completed switching.

[0021] Figure 3 shows the front and bottom views of the linked RF coaxial switch assembly. This example of the linked RF coaxial switch assembly consists of 16 (S1, S2, ..., S16) single-pole double-throw (SPDT) RF coaxial switches. Each SPDT switch has three RF coaxial connectors 10, 10a, and 10b at its bottom. The middle RF coaxial connector 10 can be selectively connected to one of the RF coaxial connectors (such as 10a or 10b).

[0022] Figure 1 shows a cross-sectional view of a single switch (S1) according to an embodiment. The coaxial RF switch S1 includes a tray 40 and a pivot 82, a pressure plate 42, push rod assemblies 50a and 50b, a cavity 70, coaxial connector assemblies 10, 10a and 10b, a base 71, and a cover 72. Push rod assemblies 50a and 50b include an upper push rod 51, a lower push rod 54, a reaction spring 52, and an inner conductor sheet 53. A flexible limiting band 59 adheres to the inner conductor sheet 53 and restricts its movement except in the vertical direction. The cavity 70 is an enclosed space formed by the combination of the base 71 and the cover 72. Coaxial connectors 10, 10a and 10b include an inner conductor core 11, an insulator 12, and a metal housing 13.

[0023] Figure 2 shows the internal structure of the switch section, the mechanical linkage structure, and the stop feedback component 90 of this utility model. The tray 41 is connected to the gear assembly 81 and the motor 80 via the tray shaft 82. The motor 80 can rotate clockwise or counterclockwise. The motor 80 applies torque to all the pressure plates 42 through the gear assembly 81 and the shaft 82, pushing the push rod assembly to perform the linkage switching of the switch. The stop component 90 includes a baffle 91, a light-emitting unit 92a and a photosensitive unit 92b, an isolation groove 93, and a printed circuit board 94. A baffle 91 is fixed to and linked to a tray 60. Light-emitting units 92a and 92b are mounted on a circuit board 94, facing each other. An isolation slot 93 is located in the circuit board 94, between the light-emitting units 92a and 92b, and below the baffle 91, allowing the baffle 91 to move freely up and down between them. When the baffle 91 moves between the light-emitting units 92a and 92b and blocks the light-emitting unit 92b from receiving light from the light-emitting unit 92a, the light-emitting unit 92b is not conductive. When the baffle 91 moves away from the light-emitting units 92a and 92b, the light-emitting unit 92b can receive light from the light-emitting unit 92a, and is in a conductive state. The on / off state of the photosensitive unit 92b can be fed back to the motor 80 drive circuit so that the motor 80 stops rotating after the switch is completed.

[0024] As shown in the attached diagram, when the motor 80 rotates counterclockwise, driving the tray 41 and pressure plate 42 to rotate counterclockwise accordingly via 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 simultaneously connects to the coaxial connectors 10 and 10a, making them conductive. Simultaneously, the lower push rod 52 of the right push rod assembly 50b is pushed upward by the reaction spring 52, causing the corresponding right inner conductor plate 53 to disengage from the coaxial connectors 10 and 10b, thus disconnecting the channel 10-10b. Similarly, when the motor 80 rotates clockwise, the tray 41 and pressure plate 42 will rotate counterclockwise accordingly, connecting all the RF ports 10 and 10b of the switches via the corresponding push rod assemblies, while disconnecting 10 and 10a. As described above, the stop feedback assembly 90 is linked to the tray 41 via the baffle 91 to achieve a stop function after the RF switch is switched.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
