Description

Technical Field

[0001] The present invention relates to the technical field of microwave switches, and particularly relates to a microwave switch based on ground detection indication. Background Art

[0002] Mechanical microwave switches are widely used in all microwave communication systems such as communication, navigation, data transmission, measurement and control, etc. Its function is to realize the switching of the channel state, loop-back up a fixed number of hardware through the switch to achieve more connection states. When some hardware fails, through the state switching of the microwave switch, the backup hardware in the system replaces the faulty hardware.

[0003] Currently, in actual use of existing microwave switches, the microwave switch cannot output an identification signal when the channel is conducting or disconnecting to let the peripheral staff know the working state of the microwave switch channel. When a certain channel of the microwave switch is made to conduct, the peripheral staff cannot clearly know whether the channel of the microwave switch has been conducted according to the control instruction. Summary of the Invention

[0004] In view of the deficiencies of the background art, the present invention provides a microwave switch based on ground detection indication. The technical problem to be solved is that existing microwave switches cannot output an identification signal indicating that the microwave switch channel is conducting or disconnecting during actual use, and peripheral personnel cannot actually understand the working state of the microwave switch channel.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A microwave switch based on ground detection indication, including a body. Inside the body, there are microwave switch channels and a connector for controlling the conduction or disconnection of the microwave switch channels. On the body, there is also a driving device for driving the connector to move up and down. The driving device includes a rotatable armature, a push rod, and an electromagnetic coil assembly. The rotating end of the armature is connected to the push rod, the push rod is connected to the connector, and the electromagnetic coil assembly is located above the armature and is configured to generate a magnetic field for driving the armature to rotate. A probe is installed insulatively inside the electromagnetic coil assembly. When the rotating end of the armature contacts the bottom of the electromagnetic coil assembly, the rotating end of the armature contacts the probe.

[0006] In a certain embodiment, there are two microwave switch channels and two connectors inside the body. The driving device includes a rotatable armature, two push rods, and two electromagnetic coil assemblies. The two rotating ends of the armature are respectively connected to a push rod, and each push rod is connected to a connector.

[0007] In a certain embodiment, a column is installed on the body, an armature stop is installed on the column, and the electromagnetic coil assembly is installed at the bottom of the armature stop.

[0008] In some embodiments, a circuit board is installed above the armature on the column, input contacts are provided on the circuit board, and the probe is electrically connected to the input contacts.

[0009] In some embodiments, the electromagnetic coil assembly includes an iron core and a coil assembly. The iron core is embedded in the coil assembly, and the probe is embedded in the iron core.

[0010] The beneficial effects of the present invention compared with the prior art are as follows: By installing a probe in the electromagnetic coil assembly of the driving device installed on the body of the microwave switch, since the electromagnetic coil assembly drives the armature to rotate, when the armature rotates to the in-place position and the connector makes the microwave switch channel conductive, one end of the armature contacts the probe. At this time, the probe is equivalent to being grounded and is a low-level signal in the digital signal. Therefore, according to this low-level signal, it can be determined whether the microwave switch channel of the microwave switch is conductive, and thus peripheral personnel can understand the working state of the microwave switch channel.

[0013] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0014] As Figure 1 shown, a microwave switch based on ground detection indication includes a body 1. A microwave switch channel and a connector 2 for controlling the conduction or disconnection of the microwave switch channel are provided in the body 1. A driving device for driving the connector 2 to move up and down is further provided on the body 1. The driving device includes a rotatable armature 4, a push rod 3, and an electromagnetic coil assembly. The rotating end of the armature 4 is connected to the push rod 3, the push rod 3 is connected to the connector 2, and the electromagnetic coil assembly is located above the armature 4 and is configured to generate a magnetic field for driving the armature 4 to rotate. A probe 7 is installed in the electromagnetic coil assembly 5 in an insulated manner. When the rotating end of the armature 4 contacts the bottom of the electromagnetic coil assembly, the rotating end of the armature 4 contacts the probe 7.

[0015] Specifically, in Figure 1In it, there are two microwave switch channels and two connectors inside the body 1. The two microwave switch channels are distributed left and right inside the body. Among them, one microwave switch channel is composed of two adjacent conductors at the bottom of the body 1 and a groove (not marked in the figure) opened in the body part. The driving device includes a rotatable armature 4, two push rods 3, and two electromagnetic coil assemblies. The two rotating ends of the armature 4 are respectively connected to a push rod 3, and each push rod 3 is connected to a connector 2. During actual use, when the armature 4 rotates to the left, the rotating end on the left side of the armature 4 drives the corresponding push rod to move downward, and then drives the corresponding connector 2 to move downward. After the connector 2 moves downward in place, the rotating end on the right side of the armature 4 contacts the bottom of the electromagnetic coil assembly on the right side. At this time, the probe 7 in the electromagnetic coil assembly on the right side contacts the rotating end on the right side of the armature 4 and is grounded, outputting a low-level signal. Therefore, according to the low-level signal output by this probe 7, it can be judged whether the microwave switch channel in the microwave switch is conducting. Similarly, according to the low-level signal output by the probe 7 in the electromagnetic coil assembly on the left side, it can be judged whether the microwave switch channel on the right side of the microwave switch is conducting.

[0016] In a certain implementation manner, three, four, or more than four microwave switch channels can be provided inside the body 1 of the microwave switch. Specifically, it can be determined according to actual needs. Just put the corresponding probe in the electromagnetic coil assembly that controls the conduction or disconnection of the corresponding microwave switch channel to achieve the conduction detection of the corresponding microwave switch channel. The detection principle is as described in the previous paragraph.

[0017] Specifically, in this embodiment, the electromagnetic coil assembly includes an iron core 6 and a coil assembly 5. The iron core 6 is embedded in the coil assembly 5, and the probe 7 is embedded in the iron core 6.

[0018] Specifically, in this embodiment, a column 8 is installed on the body 1, an armature 9 is installed on the column 8, and the electromagnetic coil assembly is installed at the bottom of the armature 9. During actual use, the magnetic lines of force generated by the electromagnetic coil assembly can be enclosed inside through the armature 9 to improve the efficiency of the iron core 6.

[0019] Specifically, in this embodiment, a circuit board 10 is installed above the armature 9 on the column 8. The circuit board 10 is provided with input contacts, and the probe 7 is electrically connected to the input contacts. During actual use, the peripheral monitoring system can detect the voltage signal at the input contacts on the circuit board 10 to detect whether the corresponding microwave switch channel has been conducted according to the control instruction.

[0020] In summary, in the present invention, a probe 7 is installed in the electromagnetic coil assembly of the driving device mounted on the body 1 of the microwave switch. Since the electromagnetic coil assembly drives the armature 4 to rotate, when the armature 4 rotates to the in-place position, that is, when the connector 2 makes the microwave switch channel conductive, one end of the armature 4 contacts the probe 7. At this time, the probe 7 is equivalent to being grounded and is a low-level signal in the digital signal. Therefore, according to this low-level signal, it can be judged whether the microwave switch channel of the microwave switch is conductive, and thus the peripheral personnel can understand the working state of the microwave switch channel.

[0021] Based on the inspiration of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
