Description

Technical Field

[0001] This utility model belongs to the technical field of medical technology, specifically relating to a simple radio frequency testing platform. Background Technology

[0002] Radio frequency amplifiers can be classified into high-gain amplifiers, low-noise amplifiers, and medium-to-high power amplifiers. The core of the amplifier circuit is the microwave transistor.

[0003] Radio frequency amplifier equipment often causes imaging signal abnormalities due to radio frequency signal instability during use. The spare parts that need to be replaced after the signal abnormality are mainly imported, and the original manufacturer's repair time is long, which affects the normal use of medical equipment with radio frequency amplifiers and is not conducive to the progress of the company's services.

[0004] Therefore, it is necessary to periodically test the stability of the RF signal of the RF amplifier. The testing steps for the RF amplifier are as follows: The testing steps for RF amplifier 4 are roughly as follows:

[0005] Connect to a 10MB signal radio frequency source;

[0006] Connect to R232 communication signals and parallel port feedback board;

[0007] Connect to a 380V power supply;

[0008] Connect to an RF load (Note: RF amplification power is 18KW 64MB, with high radiation);

[0009] After connecting the above components and turning on the power, the computer software platform can view and analyze the test results. However, currently, when testing RF amplifiers, there is no corresponding protection mechanism in the circuit. When problems such as voltage instability occur during the RF amplifier testing process, the RF amplifier cannot be quickly disconnected, resulting in the RF amplifier being subjected to continuous influence for a long time, which can easily damage the RF amplifier. Therefore, this application proposes a simplified RF test platform. Utility Model Content

[0011] To achieve the above objectives, this utility model provides the following technical solution: a simple radio frequency test platform, including a power supply and a test device, wherein the test device is connected to the power supply, characterized in that the test device is used to test a radio frequency amplifier, wherein the radio frequency amplifier is provided with a connector and a first conductive rod, the first conductive rod being located inside the connector;

[0015] The push-pull plate is connected to the moving plate via a vertical plate. An elastic component is set between the vertical plate and the connecting piece. The push-pull plate has a connected horizontal groove and an arc groove. The connecting rod is installed on the rotating plate.

[0025] Beneficial effects:

[0026] This utility model provides a simple radio frequency (RF) test platform. When the power-off button is pressed downwards, the arc-shaped groove on the power-off button moves downwards. During the downward movement, it pushes the arc-shaped connecting groove in the rotating plate, causing the rotating plate to rotate.

In this way, when an abnormal phenomenon occurs during the test, the test device and the RF amplifier can be quickly separated, avoiding continuous damage to the RF amplifier and the test device.

[0034] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0035] like Figures 1-5As shown in the figure, this utility model provides a simple radio frequency (RF) test platform, including a power supply 2 and a test device 3. The test device 3 is connected to the power supply 2 and is used to measure the stability of the RF signal of the RF amplifier 4. The test device 3 internally includes a signal RF source, a communication signal and parallel port feedback board, an RF load, and a computer.

[0036] The testing steps for RF amplifier 4 are roughly as follows:

[0037] Connect to a 10MB signal radio frequency source;

[0038] Connect to R232 communication signals and parallel port feedback board;

[0039] Connect to a 380V power supply 2;

[0040] Connect to an RF load (Note: RF amplification power is 18KW 64MB, with high radiation);

[0041] After connecting the above, turn on power 2, and the computer software platform will control the evaluation results.

[0042] It also includes a test base plate 1, a power supply 2, and a test device 3, all of which are mounted on the test base plate 1. The test base plate 1 has a storage slot for storing the radio frequency amplifier 4.

[0043] Specifically, the RF amplifier 4 is provided with a connector 401 and a first conductive rod 402, with the first conductive rod 402 located inside the connector 401.

[0044] In order to connect the RF amplifier 4 to the test device 3, the simplified RF test platform also includes a connector 5, a second conductive rod 6, a connecting wire 7, and a power failure protection mechanism 8.

[0045] Specifically, the connector 5 is connected to the connector 401. It should be noted that the connector 5 is provided with an internal thread structure, and the connector 401 is provided with an external thread structure that mates with the connector 5. That is, the connector 5 and the connector 401 are connected by threads. The second conductive rod 6 is inserted into the connector 5, and the second conductive rod 6 is connected to the test device 3 through the connecting wire 7.

[0046] When the second conductive rod 6 abuts against the first conductive rod 402, the two are connected, and the circuit between the RF amplifier 4 and the test device 3 is in a closed state. When the second conductive rod 6 separates from the first conductive rod 402, the circuit between the RF amplifier 4 and the test device 3 is in an open state.

[0047] In order to disconnect the RF amplifier 4 from the test device 3 and other components in a timely manner in case of an emergency, a power-off protection mechanism 8 is provided. The power-off protection mechanism 8 includes a protective sleeve 801, a movable plate 802, a vertical plate 805, and an elastic component 806. The second conductive rod 6 is inserted into the protective sleeve 801, and the movable plate 802 is connected to the second conductive rod 6. Specifically, the second conductive rod 6 is inserted into the circular plate, and the connection between the second conductive rod 6 and the circular plate is insulated. The second conductive rod 6 and the first conductive rod 402 can only be connected in the area where they can contact each other, and the remaining areas need to be insulated accordingly. A compression spring 803 is provided between the movable plate 802 and the circular plate, and the two ends of the compression spring 803 are connected to the movable plate 802 and the circular plate respectively.

[0048] The compression spring 803 can compress the circular plate when the test device 3 and the RF amplifier 4 are normally connected, so that the second conductive rod 6 connected to the circular plate can always press on the first conductive rod 402, allowing the test device 3 and the RF amplifier 4 to be electrically connected.

[0049] Specifically, the protective sleeve 801 is provided with two vertically distributed movable slots 804. The upper and lower ends of the movable plate 802 are respectively inserted into the two movable slots 804, and the movable plate 802 can slide along the movable slots 804.

[0050] More specifically, the movable plate 802 is connected to the vertical plate 805, and the elastic component 806 is disposed between the vertical plate 805 and the connector 5. The elastic component 806 can also be a spring. The elastic component 806 can push the movable plate 802 and the vertical plate 805 to move away from the connector 5. When the vertical plate 805 moves, it can pull the circular plate and the second conductive rod 6 by squeezing the spring 803, thereby disconnecting the test device 3 from the RF amplifier 4. In this way, if an abnormal phenomenon occurs during the test, the test device 3 and the RF amplifier 4 can be quickly separated, avoiding continuous damage to the RF amplifier 4 and the test device 3.

[0051] In order for the elastic component 806 to be activated by manual intervention and to disconnect the circuit between the test device 3 and the radio frequency amplifier 4, the power failure protection mechanism 8 also includes a push-pull plate 807, a connecting rod 810, a rotating plate 811, and a power failure pressing component 812. The push-pull plate 807 is connected to the vertical plate 805. The push-pull plate 807 is provided with a horizontal groove 808 and an arc groove 809. The arc groove 809 is connected to the horizontal groove 808. The center of the arc groove 809 coincides with the center of the rotating plate 811. The connecting rod 810 is installed on the rotating plate 811. The power failure pressing component 812 is provided with an arc pattern. The rotating plate 811 is provided with an arc connecting groove that matches the arc pattern.

[0052] Pressing the power-off button 812 downwards causes the arc-shaped pattern on the power-off button 812 to move downwards. During this downward movement, it pushes the arc-shaped connecting groove in the rotating plate 811, causing the rotating plate 811 to rotate. The connecting rod 810 on the rotating plate 811 enters the horizontal groove 808 along the arc-shaped groove 809. At this time, the elastic component 806 can push the push-pull plate 807 and the vertical plate 805 to move. The second conductive rod 6 separates from the first conductive rod 402, and the circuit connecting the test device 3 and the RF amplifier 4 also separates. The rotating plate 811 does not rotate, and the connecting rod 810 is inserted into the arc-shaped groove 809. The obstruction of the connecting rod 810 prevents the push-pull plate 807 from moving even when pushed by the elastic component 806.

[0053] It should be noted that a spring is installed inside the rotating plate 811, and the other end of the spring abuts against the power-off pressing part 812.

[0054] In summary, this utility model embodiment provides a simple radio frequency (RF) test platform. When the power-off pressing component 812 is pressed downwards, the arc-shaped texture on the power-off pressing component 812 moves downwards. During the downward movement, it pushes the arc-shaped connecting groove in the rotating plate 811, causing the rotating plate 811 to rotate. The connecting rod 810 on the rotating plate 811 enters the horizontal groove 808 along the arc-shaped groove 809. At this time, the elastic component 806 can push the push-pull plate 807 and the vertical plate 805 to move. The second conductive rod 6 separates from the first conductive rod 402, and the circuit connecting the test device 3 and the RF amplifier 4 is also separated. In this way, when an abnormal phenomenon occurs during the test, the test device 3 and the RF amplifier 4 can be quickly separated, avoiding continuous damage to the RF amplifier 4 and the test device 3.

[0055] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
