Description

Technical Field

[0001] The invention relates to the technical field of power divider testing, and in particular to a testing tool for testing a radio frequency power divider. Background Art

[0002] A power divider is a device used to distribute input power in a radio frequency system. Its function is to distribute the power of the same input port to two or more output ports. It is usually used in antenna systems, transceivers, and radio frequency test equipment. Power dividers are very important in radio frequency systems to avoid signal interference and improve the flexibility and reliability of the system. When testing a power divider, the test equipment is required to perform a standing wave ratio test on the power divider.

[0003] Common power divider test equipment is to place the connected power divider directly on the desktop when in use, and test the standing wave ratio of the power divider through a network analyzer connected to the power divider. The network analyzer and the power divider are connected by a long connecting line, and the power divider placed on the desktop cannot be fixed in position when in use. When the connecting line connecting the power divider and the network analyzer is shaken, it will cause poor connection between the interfaces at both ends of the connecting line and the connection position of the power divider and the network analyzer. In addition, the commonly used test equipment cannot be used for both installation and fixing of the power divider and testing of the power divider when in use, and its functionality is relatively single.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the present invention is used, the staff can understand the test results of the power divider at any time through the folding display screen, and can also test and use the power divider while connecting, installing and fixing the power divider. When the staff has finished testing the power divider, the disassembled analyzer and filter can be placed in the two protective boxes respectively. When the folding display screen is folded, the tops of the two protective boxes will also abut against each other, so that the two protective boxes can store the analyzer and the filter. At the same time, when in use, because the two ends of the top of the folding display screen abut against each other, and the two protective boxes abut against each other, the first bottom plate, the second bottom plate and the two protective boxes cooperate with each other when in use, which can play a better protective role for the items stored in the first bottom plate, the second bottom plate, the folding display screen and the two protective boxes, and at the same time, it is convenient for the staff to take the analyzer and the filter for use again when testing the remaining power dividers again.

[0018] In the present invention, the two support plates and the baffle cooperate with each other to clamp the filter in the front-to-back direction, and the two support plates can clamp the end of the filter close to the power divider in the left-right direction, so that the filter is more stable when in use. The power divider is placed inside the support groove on the top of the support plate, so that the two support grooves support the power divider. The filter can limit the position of the power divider through the two support plates to prevent the power divider from moving in the direction close to the first bottom plate when in use. The partition can isolate the two analyzers to prevent the two analyzers from contacting each other during use, resulting in the two analyzers affecting each other.

[0019] In the present invention, the filter is connected to the two analyzers through a power divider, so the baffle and the two support plates can fix the positions of the two analyzers through the filter and the power divider, making the filter, the power divider and the two analyzers more stable when in use, because the two ends of the power divider are respectively located inside the first bottom plate and the second bottom plate, and the two ends of the power divider are respectively abutted against the inner wall of the support groove and the partition plate, which can prevent the first bottom plate and the second bottom plate from folding when in use.

[0020] After the staff of the present invention has finished testing the power divider, the staff can take out and disassemble the filter, the power divider and the two analyzers, and move the folding display screen to the top of the first bottom plate and the second bottom plate by rotating the plate, and fold the folding display screen, and the first bottom plate and the second bottom plate will also be folded. When storing the test tooling, the occupied space can be reduced, and at the same time, the inside of the first bottom plate and the second bottom plate can be better protected, and the analyzer and filter used for the test can also be stored.

[0039] As a technical optimization scheme of the present invention, a placement groove 15 is provided at one end of the first bottom plate 1 and the second bottom plate 2 away from the opposite surface, and through holes 16 are provided on both sides of the inner top of the placement groove 15 in the length direction. The two placement grooves 15 are respectively connected to the interior of the first bottom plate 1 and the second bottom plate 2 through the through holes 16, and a concave protective box 11 is slidably installed inside the placement groove 15; when the staff needs to store the power divider 3 and the analyzer 4, the analyzer 4 and the filter 8 can be placed inside the two protective boxes 11.

[0040] As a technical optimization scheme of the present invention, the tops of both sides of the protective box 11 respectively penetrate the through holes 16 on both sides of the placement groove 15, and the inner bottom of the placement groove 15 is provided with a fixed groove 29 in the length direction. A guide block 23 is installed at the bottom of the protective box 11, and the guide block 23 is slidably installed inside the fixed groove 29. One end of the protective box 11 away from the opposite surfaces of the first bottom plate 1 and the second bottom plate 2 penetrates the placement groove 15; when the first bottom plate 1 and the second bottom plate 2 are folded against each other, the opposite surfaces of the two protective boxes 11 can abut against each other, which can provide a better seal for the interior of the first bottom plate 1 and the second bottom plate 2.

[0041] As a technical optimization solution of the present invention, grooves 28 are provided on both sides of the top of the first bottom plate 1 and the second bottom plate 2, close to one end of the opposite surface, and connecting plates 9 are installed at both ends of the opposite surfaces of the first bottom plate 1 and the second bottom plate 2, and the two ends of the connecting plate 9 are respectively rotatably installed in the inside of the two grooves 28 located on the same side of the top of the first bottom plate 1 and the second bottom plate 2; the connecting plate 9 can connect the first bottom plate 1 and the second bottom plate 2 when in use.

[0042] When the present invention is in use, the staff spreads out the first bottom plate 1 and the second bottom plate 2 and places them flat at the designated position on the desktop, and the staff can pull the folding display screen 6 to move the folding display screen 6 upward. At the same time, when the folding display screen 6 moves upward, the staff can push the rotating plate 5 close to the end of the threaded rod 24, so that the bottom end of the rotating plate 5 slides inside the guide groove 14 until the bottom end of the rotating plate 5 moves to the end of the guide groove 14 away from the opposite surface of the first bottom plate 1 and the second bottom plate 2. The staff can install the internal thread block 25 on the end of the threaded rod 24 away from the rotating plate 5, so that the internal thread block 25 and the rotating plate 5 cooperate with each other to rotate the first bottom plate 1 or the second bottom plate 2. When in use, the four rotating plates 5 can play a good supporting role for the folding display screen 6, and the folding display screen 6 can protect the inside of the first bottom plate 1 and the second bottom plate 2. At the same time, when in use, the staff can understand the detection status of the power divider 3 through the folding display screen 6 at any time, and can also test and use the power divider 3 while connecting and installing the power divider 3.

[0043] The staff connects the power divider 3 and the filter 8 when in use, so that the filter 8 and the input end of the power divider 3 are connected to each other, and the connected filter 8 and the power divider 3 are placed inside the second bottom plate 2. When in use, the filter 8 is located between the baffle 12 and the two support plates 13, and the end of the baffle 12 close to the power divider 3 is located between the two support plates 13. When in use, the two support plates 13 and the baffle 12 cooperate with each other to clamp the filter 8 in the front and rear directions, and the two support plates 13 can clamp the end of the filter 8 close to the power divider 3 in the left and right directions, so that the filter 8 is more stable when in use. When the staff installs the filter 8, the power divider 3 is placed inside the support groove 21 at the top of the support plate 13, so that the two support grooves 21 support the power divider 3. At the same time, when in use, the end of the power divider 3 away from the filter 8 is located inside the first bottom plate 1, and the filter 8 can limit the position of the power divider 3 through the two support plates 13 to prevent the power divider 3 from moving in the direction close to the first bottom plate 1 when in use.

[0044] The staff places the two analyzers 4 to be used on both sides of the partition 19 inside the first bottom plate 1. When in use, the partition 19 can isolate the two analyzers 4 to prevent the two analyzers 4 from contacting each other during use, resulting in the two analyzers 4 affecting each other. When in use, the partition 19 can cooperate with the two clamping plates 10 on both sides of the first bottom plate 1 to clamp the two analyzers 4 on the left and right, respectively, and can play a good role in limiting the position of the analyzers 4 when in use.

[0045] The staff pushes the partition 19 close to one end of the limit plate 20, so that the limit plate 20 and the partition 19 move in the direction of the second bottom plate 2. Because the two analyzers 4 are respectively in contact with the two ends of the side of the limit plate 20, when the limit plate 20 and the partition 19 move, the two analyzers 4 can be pushed to move in the direction of the power divider 3 until the connectors on the two analyzers 4 are respectively connected to the two output ends of the power divider 3, and the staff can fix the connection position between the output end of the power divider 3 and the analyzer 4 through the threaded sleeve. When in use, the limit plate 20 and the power divider 3 cooperate with each other to better clamp the analyzer 4, and when in use, because the two support plates 13 limit the position of the filter 8, and the filter 8 is connected to the two analyzers 4 through the power divider 3, the baffle 12 and the two support plates 13 can fix the position of the two analyzers 4 through the filter 8 and the power divider 3, so that the filter 8, the power divider 3 and the two analyzers 4 are more stable when in use. Because the two ends of the power divider 3 are respectively located inside the first bottom plate 1 and the second bottom plate 2, and the two ends of the power divider 3 are respectively in contact with the inner wall of the support groove 21 and the partition 19, the first bottom plate 1 and the second bottom plate 2 can be prevented from folding during use.

[0046] The staff connects the two analyzers 4 to the first connection blocks 26 on the bottom sides of the two rotating plates 5 on the first bottom plate 1 through connecting wires, and the second connection blocks 27 on the rotating plate 5 are connected to the folding display screen 6. The signal line, filter 8, power divider 3, analyzer 4, first connection block 26, second connection block 27 and folding display screen 6 are electrically connected to each other. When in use, the two analyzers 4 can test the power divider 3, and the test results are displayed on the folding display screen 6 as standing wave waveforms, which is convenient for the staff to understand the test results.

[0047] When the staff has finished testing the power divider 3, the staff can remove the filter 8, the power divider 3 and the two analyzers 4, and loosen the internal thread blocks 25 on the threaded rods 24 at the bottom of the four rotating plates 5. The staff pushes the bottom of the rotating plate 5 to move the bottom of the rotating plate 5 in the guide groove 14 away from the protective box 11. When the bottom of the rotating plate 5 moves, the top of the rotating plate 5 can drive the folding display screen 6 to move downward until the folding display screen 6 moves to the top of the first bottom plate 1 and the second bottom plate 2. When the second connecting block 27 located on the side of the rotating plate 5 close to the folding display screen 6 moves downward, it will enter the inside of the card slot 18. The rotating plate 5 can play a better role in fixing the position of the folding display screen 6 through the card slot 18 and the second connecting block 27.

[0048] The staff slightly presses the middle end of the foldable display screen 6, and pulls the ends of the first bottom plate 1 and the second bottom plate 2 away from the opposite surface to move upward, so that the foldable display screen 6 is folded, and the first bottom plate 1 and the second bottom plate 2 are also folded, so that the top ends of the foldable display screen 6 abut against each other. When in use, the first bottom plate 1 and the second bottom plate 2 can better protect the interior and the foldable display screen 6, and prevent external dust from entering the interior of the first bottom plate 1 and the second bottom plate 2 when stored. When the staff folds the folding display screen 6, they pull the first bottom plate 1 and the second bottom plate 2 away from the protective box 11 at one end of the opposite surface, so that the protective box 11 moves out of the placement slot 15, and the staff can place the disassembled analyzer 4 and filter 8 in the two protective boxes 11 respectively. When the folding display screen 6 is folded, the tops of the two protective boxes 11 will also abut against each other, so that the two protective boxes 11 can store the analyzer 4 and the filter 8. At the same time, when in use, because the two ends of the top of the folding display screen 6 abut against each other, and the two protective boxes 11 abut against each other, the first bottom plate 1, the second bottom plate 2 and the two protective boxes 11 cooperate with each other when in use, which can provide better protection for the items stored in the first bottom plate 1, the second bottom plate 2, the folding display screen 6 and the two protective boxes 11, and at the same time, it is convenient for the staff to take the analyzer 4 and the filter 8 for use again when testing the remaining power dividers 3 again.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
