[0031] The compression space of the compression spring 301 can facilitate the movement of the RF connector 2 when replacing the product 4 under test, thereby preventing the RF connector 2 from being damaged, thereby quickly replacing the product 4 under test and improving the efficiency of the test. The RF connector clamp 3 is provided with a compression spring 301, and due to the elastic force of the spring, it can ensure that the RF connector 2 and the product 4 under test can fit tightly and without gaps; at the same time, the compression space of the spring can facilitate the removal of the RF connector 2 when replacing the product 4 under test, and quickly replace the product 4 under test; the RF connector clamp 3 is also provided with a clamping ring 302, and the tightness of the compression spring 301 is adjusted according to the clamping degree of the clamping ring 302, thereby the tightness of the compression spring 301 can be set according to different component conditions.

[0032] Example 4 like Figure 1 As shown, one embodiment of the present invention is that two compression springs 301 are provided, and two guide rails 102 are also provided, and two retaining rings 302 are provided accordingly; one end of the compression spring 301 is connected to the third linear bearing 304, and the other end is connected to the first linear bearing 223; The guide rail 102 is symmetrically arranged on the main frame 1, and the first linear bearing 223, the second linear bearing 401 and the third linear bearing 304 are also symmetrically arranged and connected to the guide rail 102.

[0033] Due to the elastic force of the spring, it can be ensured that the RF connector 2 and the product under test 4 can fit tightly without any gap; at the same time, the compression space of the spring can facilitate the removal of the RF connector 2 when replacing the product under test 4, and quickly replace the product under test 4; a clamping ring 302 is also provided in the RF connector clamping part 3, and the tightness of the compression spring 301 is adjusted according to the clamping degree of the clamping ring 302, thereby the tightness of the compression spring 301 can be set according to different component conditions.

The product under test 4 is used to connect with the RF connector 2. A glass bead needle 402 is arranged on the product under test 4, and the moving direction of each component on the guide rail 102 is single, so as to ensure that the RF connector 2 will not exert radial shear force on the glass bead needle 402 due to movement, thereby protecting the glass bead needle 402. The input and output ports are led out using RF glass beads, and the close fit between the RF connector 2 and the cavity of the product under test 4 prevents the glass bead needle 402 from leaking out during testing, so that the isolation of each channel during testing is not affected. Therefore, the device of this embodiment has a high isolation.

[0036] Example 6 like Figure 1 As shown, one embodiment of the present invention is that the RF connector 2, the RF connector clamping piece 3 and the product under test 4 are all arranged on the main frame 1, and the RF connector 2, the RF connector clamping piece 3 and the product under test 4 are all slidably connected to the guide rail 102; the positional relationship of the device is: the fixed RF connector 201 is arranged above the product under test 4, the movable RF connector 202 is arranged below the product under test 4, and the RF connector clamping piece 3 is arranged below the movable RF connector 202.

In addition, the setting method of this embodiment can quickly disassemble and assemble the product under test 4, and at the same time can ensure the stability of the connection and contact of the product under test 4, so that the test result is more accurate.

[0038] Example 7 like Figure 6 As shown, another embodiment of the present invention is a method for using a high-isolation rapid assembly and disassembly test device for a radio frequency module, the method comprising the following steps: Establish a coordinate axis, with one corner of the main frame 1 as the coordinate origin O, the frame 101 in the vertical direction of the guide rail 102 as the Y axis, the frame 101 parallel to the first RF connector mounting plate 212 as the X axis, and the XOY plane formed by the X axis and the Y axis as the Z axis; set the RF module high isolation rapid assembly and disassembly test device in the positive direction of the Y axis and the X axis; Assembling the product under test 4: installing the first RF connector 211 of the fixed RF connector 201 on the first RF connector mounting plate 212 by screws, and the first RF connector 211 penetrates the first RF connector mounting plate 212; connecting the product under test 4 to the fixed RF connector 201 by a glass bead needle 402, and installing the product under test 4 on the product mounting plate 5; the product under test 4 is arranged to be connected with the movable RF connector 202, the product under test 4 is arranged on the product mounting plate 5, and the second RF connector mounting plate 222 is further provided with a second RF connector 221, the second RF connector 221 is installed on the first linear bearing 223 through the first linear bearing mounting plate 224, and the first linear bearing 223 is connected to the guide rail 102; the RF connector clamping piece 3 is arranged between the movable RF connector 202 and the guide rail 102, and the product under test 4 is assembled by the RF connector clamping piece 3; When using the test device, the retaining ring 302 is adjusted to a suitable position according to the size of the product 4 under test, and is locked on the guide rail 102. When the product 4 under test is clamped, the movable RF connector 202 needs to be moved to the negative direction of the Y axis first. During this process, the compression spring 301 will be compressed, and then the glass bead needle 402 of the product 4 under test is inserted into the movable RF connector 202, and the pressure of the compression spring 301 is gradually released. Then, the glass bead needle 402 at the other end of the product 4 under test is inserted into the fixed RF connector 201 and connected to each other; wherein, the product 4 under test is provided with a glass bead needle 402, and the fixed RF connector 201 and the movable RF connector 202 are both provided with a fixing hole 6. The product under test is connected to the RF connector 2 by inserting the glass bead needle 402 into the RF connector 2; under the pressure of the compression spring 301, the positions of the RF connector 2 and the product 4 under test are fixed, and the greater the pressure of the compression spring 301, the more stable the fixation of the RF connector 2 and the product 4 under test is, and the test isolation can be better guaranteed. The pressure of the compression spring 301 is adjusted by the snap ring 302. The closer the snap ring 302 is to the positive direction of the Y axis, the greater the pressure of the compression spring 301.

[0039] Disassembling the product under test 4: First, move the active RF connector 202 in the positive direction of the Y axis; then move the product under test 4 in the positive direction of the Y axis, and finally take the product under test 4 out in the positive direction of the Z axis; wherein, the moving distance of the active RF connector 202 is greater than the sum of the moving distance of the product under test 4 and the length of the glass bead needles 402 at both ends of the product under test 4.

[0040] The order of assembling the product under test 4 and disassembling the product under test 4 is opposite, but both require the RF connector clamping part 3 to adjust the gap between the product under test 4 and the RF connector 2. The device is disassembled by increasing the gap and assembled by reducing the gap.

[0041] Example 8 Another embodiment of the present invention is to set the moving distance of the active RF connector 202 to be , the distance moved by the product 4 under test is , and the length of the glass bead needle 402 of the tested product 4 is ; ; ; This completes the disassembly of the tested product 4.

[0042] When disassembling the tested product 4, it is necessary to first move the active RF connector 202, and then move the tested product 4. Therefore, the moving distance of the active RF connector 202 is greater than that of the tested product 4 to ensure that the tested product 4 is successfully disassembled. In addition, since the tested product 4 is provided with a glass bead needle 402, the glass bead needle 402 extends into the fixed RF connector 201 for connection, so the moving distance of the tested product 4 is Should be greater than the length of glass bead needle 402 , so as to meet the separation of the tested product 4 from the fixed RF connector 201; and the moving distance of the movable RF connector 202 minus the moving distance of the tested product 4 needs to be greater than the length of the glass bead needle 402 This is to enable the product under test 4 to be taken out from the active radio frequency connector 202. Finally, the product under test 4 can be taken out smoothly in the positive direction of the Z axis.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
