Description

Technical Field

[0001] This invention belongs to the field of radio frequency port testing technology, and specifically relates to a testing device for multi-radio frequency port TR components. Background Technology

[0002] Multi-RF port transceiver (TR) modules are core transceiver components in electronic systems such as phased array radars. They integrate multiple independent RF interfaces, employ a split structure design, and support plug-and-play connections, enabling the transmission and reception of RF signals. Because they are required to perform precise transmission and processing of high-frequency signals in radar detection, communication, and other scenarios, comprehensive functional testing must be conducted before manufacturing and packaging to ensure that each RF interface meets performance standards and is of good quality.

[0003] However, the structural characteristics of these components present significant challenges to testing. Their RF ports are characterized by high density and small size, typically arranged in a three-row, dense layout with extremely small interface spacing and narrow space, while also needing to meet high-frequency testing requirements. In related technologies, testing multi-RF port TR components mainly relies on manual insertion and removal operations, specifically in two ways: one is to insert and remove the RF interfaces one by one, testing each interface and then removing it, testing all interfaces sequentially; the other is to manually insert all interfaces and then test them individually or as a whole.

[0004] However, due to the limitations of the component structure, manual insertion and removal presents many problems. On the one hand, the dense and closely spaced RF ports result in extremely limited operating space, making it easy for interference between interfaces to occur during manual insertion and removal. This not only requires applying considerable force to complete the insertion and removal action, making the operation difficult, but also necessitates repeated insertion and removal for each test, which is time-consuming and labor-intensive, seriously affecting testing efficiency. On the other hand, it is difficult to accurately control the insertion and removal force manually. Excessive force can easily cause mechanical damage to the RF ports (such as interface deformation, internal pin breakage, etc.), while uneven force may lead to unstable interface connections. Especially in high-frequency testing scenarios, fluctuations in connection stability will directly affect signal transmission quality, thereby causing test results to be distorted and affecting the accurate judgment of component performance.

[0032] Beneficial effects:

[0033] 1. This invention uses a drive unit to move a guide block in the X-axis, and utilizes the cooperation of the guide groove and the follower assembly to move the test connector of the RF cable assembly a fixed distance in the Y-axis, thus achieving automatic insertion and removal of the test connector and the interface of the product under test. This replaces manual operation, avoids the problem of limited operating space caused by the dense and small spacing of RF ports, eliminates the need for repeated application of large forces, significantly reduces the difficulty of operation, and reduces the number of insertions and removals per test, significantly improving testing efficiency and saving labor costs.

[0034] 2. The positioning unit for positioning the product under test in this invention uses a fixed pin, a movable pin, and a three-way adjustable support to accurately fix the product under test, ensuring that the test connector and the interface are in the same position, reducing docking deviation, avoiding difficulty in mating or excessive insertion and removal force caused by positional deviation between the test connector and the interface, and improving the feasibility of mating the test connector and the interface.

[0035] 3. This invention provides rolling support for the movement of the RF cable assembly by sliding the bearing assembly with the guide rail below it, reducing frictional resistance and ensuring smooth and stable movement, thus preventing tilting or shaking during operation. The lead screw and linear guide rail of the drive unit work together to ensure the accuracy of the guide block's movement, thereby ensuring the smoothness of the test connector insertion and removal process, improving the reliability of equipment operation and the repeatability of testing.

[0036] 4. This invention avoids the problem of excessive total force caused by simultaneously plugging and unplugging all interfaces by dividing the densely packed test interfaces into multiple groups for plugging and unplugging tests, thus reducing the load requirements on the drive structure and improving the feasibility of the equipment. Simultaneously, the protective plate can fix the RF cable assembly in the non-test state, preventing damage to internal components due to shaking and collisions, and extending the service life of the equipment.

[0058] The invention will be more readily understood by referring to the following detailed description of preferred embodiments and included examples. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of conflict, the definitions in this specification shall prevail.

[0059] This invention provides a multi-RF port TR component testing device, which solves the problems of time-consuming and labor-intensive manual testing of RF test ports, which requires applying large force when plugging and unplugging test ports, and the inability to accurately control the force when plugging and unplugging test ports, which easily leads to damage to test ports and inaccurate test results.

[0060] The technical concept of this invention lies in using a drive component to move a guide block linearly in the X-axis. A guide groove is provided on the guide block, and during its movement, the guide groove drives the camshaft follower of the RF cable assembly to move in the Y-axis, allowing the test connector of the RF cable assembly to be inserted into the test interface. When the guide block moves in the reverse direction, the test connector of the RF cable assembly can be separated from the test interface. The distance the RF cable assembly moves along the Y-axis remains constant, thus enabling easier connection of the test connector to the test interface without damaging it. This effectively improves efficiency, saves manpower, avoids damage to the test interface, and ensures the accuracy of test results.

[0061] like Figures 1-13 As shown, one embodiment of the present invention provides a multi-RF port TR component testing device for simultaneously testing multiple RF ports, i.e., test interfaces, of a multi-RF port TR component. The structure of the multi-RF port TR component is described below. Figure 13 As shown, the device under test (DUT) has 80 test interfaces to be tested, including 64 SMPS interface test ports (610) and 16 SMPM interface test ports (620). Each test interface has a certain escapement force. The force required to insert and remove all 80 test ports simultaneously is not simply the sum of the escapement forces of the individual 80 test ports. This is because, due to tolerances, relative positions, and other factors, the insertion and removal force of all 80 test ports simultaneously is much greater than the sum of the escapement forces of the individual 80 test ports. Based on these reasons, this application divides the 80 test interfaces into 16 groups, with each group containing 5 test interfaces (4 SMPS interfaces and 1 SMPM interface) for insertion and removal testing.

[0062] The following embodiments illustrate a multi-RF port TR component testing device, including a base assembly 100; wherein the base assembly 100 is a box-type structure, and its upper surface is provided with a removable upper cover plate 110.

[0063] A drive unit 200 is disposed within the base assembly 100, and the guide block 230 of the drive unit 200 moves along a predetermined path. In one embodiment, the drive unit 200 is disposed inside the base assembly 100 and is arranged along the long side of the base assembly 100. One end of the drive unit 200 may be connected to a handwheel 210, and by rotating the handwheel 210, the guide block 230 moves along the predetermined path. Specifically, the guide block 230 moves along the long side of the base assembly 100, that is, along the X-direction. In some other feasible embodiments, the handwheel 210 may also be replaced by a drive motor.

[0064] A test unit 300 is disposed within the base assembly 100, and multiple RF cable assemblies 340 within the test unit 300 are distributed along a predetermined path of the guide block 230. When the guide block 230 moves along the predetermined path, it abuts against the RF cable assemblies 340, causing the test connectors 343 of the RF cable assemblies 340 to move a fixed distance along a preset direction. In one embodiment, multiple RF cable assemblies 340 are arranged side-by-side, with their test connectors 343 all facing the same side. During the movement of the guide block 230 along the predetermined path, the guide groove 231 of the guide block 230 contacts the RF cable assemblies 340, allowing the RF cable assemblies 340 to move a certain distance. This movement of the test connectors 343 to a fixed distance enables insertion into the corresponding test interface. It should be noted that "the same side" refers to the side facing the test interface; in this embodiment, the test connectors 343 face the side of the guide block 230's movement path.

[0065] A positioning unit 400 is disposed on one side of the test unit 300. The positioning unit 400 is used to fix the product under test (DUT) 600, ensuring that the test connectors 343 corresponding to the multiple test interfaces of the DUT 600 are in the same position. By setting up the positioning unit 400, the DUT 600 can be fixed, ensuring the stability of the positioning unit 400 during testing and preventing shaking. On the other hand, the positioning unit 400 can also pre-adjust the position of the test interfaces and test connectors 343 to ensure accurate alignment during insertion and removal, avoiding damage to the test interfaces due to positional errors.

[0066] like Figures 3-4As shown, in one embodiment, the drive unit 200 includes a lead screw 220, which is exemplarily a ball screw 220;

[0067] The guide block 230 is threadedly connected to the lead screw 220 so that when the lead screw 220 rotates, it drives the guide block 230 to move linearly. When the ball screw 220 rotates circumferentially, it can drive the guide block 230 to move along the length direction of the ball screw 220.

[0068] Guide groove 231 is formed on the surface of guide block 230. In one embodiment, guide groove 231 is formed on the upper and lower surfaces of guide block 230, and two guide grooves 231 are formed on both the upper and lower surfaces of guide block 230. The guide grooves 231 on the same surface are symmetrically arranged with respect to the center of the surface. By setting two guide grooves 231, the follower assembly 344 is driven to move, which in turn drives the radio frequency cable assembly 340 to move, so that the test connector 343 is inserted into the test interface.

[0069] The linear guide 240 is arranged in the same direction as the ball screw 220. One side of the guide block 230 is slidably connected to the linear guide 240. The linear guide 240 plays a supporting and guiding role. The side of the guide block 230 can be supported by the linear guide 240. At the same time, due to the presence of the linear guide 240, the guide block 230 will not rotate with the ball screw.

[0070] like Figure 3 As shown, in one embodiment, a limiting member 250 corresponding to the position of the guide block 230 is provided inside the base assembly 100. Exemplarily, the limiting member 250 is a limiting screw. Since the limiting screw is located on the inner wall of the base assembly 100, the movement range of the guide block 230 can be limited. This prevents the guide block 230 from colliding with the components at both ends of the ball screw, and reduces the idle stroke of the guide block 230, saving working time. In one embodiment, a rubber pad can be provided at the end of the limiting screw to effectively prevent hard contact between the guide block 230 and the limiting screw.

[0071] like Figure 4As shown, in one embodiment, the guide groove 231 includes a first expansion section 2311, a compression section 2312, and a second expansion section 2313. When the cam 3442 in the follower assembly 344 enters the first expansion section 2311, it enters the compression section 2312 along the first expansion section 2311. Since the distance from the compression section 2312 to the edge of the guide block 230 is longer than the distance from the first expansion section 2311 to the edge of the guide block 230, after the cam 3442 enters the compression section 2312, it drives the follower assembly 344 and then drives the RF cable assembly 340 to move towards the guide block 230, thereby inserting the test connector 343 into the test interface. When the guide block 230 moves in the reverse direction, the cam 3442 first enters the second expansion section 2313 and then enters the compression section 2312. Since the compression section 2312 is shorter than the second expansion section 2313 in distance from the edge of the guide block 230, after the cam 3442 enters the compression section 2312, it drives the follower assembly 344 and then drives the RF cable assembly 340 to move away from the guide block 230, thereby separating the test connector 343 from the test interface, and thus realizing the insertion and removal of the test connector 343 from the test interface.

[0072] like Figure 4 As shown, in one embodiment, two guide grooves 231 on the same surface are centrally symmetrically arranged, which is mainly used when the positions of the cams 3442 of the follower assemblies 344 in two adjacent RF cable assemblies 340 are inconsistent. Specifically, the distance from the cam 3442 of one RF cable assembly 344 to the center of the follower assembly 344 is greater than the distance from the cam 3442 of the follower assembly 344 to the center of the follower assembly 344 in the other RF cable assembly 340.

[0073] like Figures 6-8 As shown, in one embodiment, the test unit 300 includes two support legs 310 on both sides. An adjustment frame 320 is provided at the upper end of the support leg 310, and a cover plate 330 is provided at the upper end of the adjustment frame 320. The support legs 310 are plate-like structures on both sides of the test unit 300. The support legs 310 can limit and protect the internal structure of the test unit 300. The adjustment frame 320 provided above the support legs 310 can fix the support legs 310. At the same time, the cooperation between the adjustment frame 320 and the cover plate 330 can also provide a fixed foundation for the bearing assembly 350 located above the radio frequency cable assembly 340.

[0074] Multiple sets of RF cable assemblies 340 are arranged in parallel between the two side feet 310. Specifically, the multiple RF cable assemblies 340 are arranged in the same direction, so that the multiple test connectors 343 at one end of the multiple RF cable assemblies 340 correspond to the test interface positions of the product under test 600, which facilitates subsequent testing.

[0075] The bearing assembly 350 is located at least below the RF cable assembly 340. The bearing assembly 350 is slidably connected to the lower part of the RF cable assembly 340. The bearing assembly 350 is mounted on the base assembly 100 to support the RF cable assembly 340, providing support and positioning for the cable assembly. It also provides a rolling kinematic pair for the movement of the cable assembly, which can improve the smoothness of movement and reduce the friction of movement.

[0076] like Figure 8 As shown, the RF cable assembly 340 includes a frame 341, with multiple RF cables 342 passing through the frame 341. Test connectors 343 of the RF cables 342 are fixed to the outer surface of the frame 341. Each RF cable assembly 340 has five test connectors 343 at its end, four of which correspond to the SMPS interface and one to the SMPM interface. Specifically, the four test connectors 343 corresponding to the SMPS interface are arranged around the test connector 343 corresponding to the SMPM interface.

[0077] Follower assembly 344 is disposed on one side of frame 341 and is adapted to guide block 230; wherein, follower assembly 344 is detachably connected to one end of frame 341 by screws for easy replacement.

[0078] A guide rail 345 is provided at least at the bottom of the frame 341, and the guide rail 345 is adapted to the bearing assembly 350. The movement path of the radio frequency cable assembly 340 can be restricted by the cooperation between the guide rail 345 and the bearing assembly 350.

[0079] like Figure 8 As shown, the follower assembly 344 includes a frame 3441. Cams 3442 are arranged on the upper and lower sides of the frame 3441, and the cams 3442 are located inside the guide groove 231. Each follower assembly 344 has two cams 3442, one upper and one lower. The mounting positions of the cams 3442 of two adjacent RF cable assemblies 340 correspond to the positions of the guide grooves 231. Specifically, if the cam 3442 of one follower assembly 344 engages with the guide groove 231, then the cam 3442 of an adjacent RF cable assembly 340 is mounted and engages with another guide groove 231 on the same surface.

[0080] In addition, since cams 3442 are provided at the top and bottom of the frame 3441 of each follower assembly 344, the upper and lower cams 3442 can be used in conjunction with the guide grooves 231 on the upper and lower surfaces of the guide block 230. On the one hand, this can ensure the stability of the guide block 230 during linear motion, and on the other hand, it can also ensure the stability of the overall movement of the RF cable assembly 340 when the follower assembly 344 drives the RF cable assembly 340 to move. This avoids the RF cable assembly 340 tilting due to the upper part moving while the bottom does not move, which would affect the normal docking and testing of the test connector 343 and the test interface.

[0081] like Figure 3 As shown, the number and position of the bearing assemblies 350 are adapted to the RF cable assembly 340, and adjacent bearing assemblies 350 are staggered. Specifically, the staggered arrangement of the bearing assemblies 350 means that among two adjacent bearing assemblies 350, one bearing assembly 350 is positioned closer to the other side of the base assembly 100, thus forming a staggered arrangement of the bearing assemblies 350. Since the bearing assemblies 350 are used to support the RF cable assembly 340 above, and the test connectors 343 of the RF cable assembly 340 need to correspond to the test interfaces, the spacing between the test interfaces is limited. To ensure that the test connectors 343 can be properly plugged in and out of the test interfaces, the bearing assemblies 350 are staggered to avoid mutual interference between the bearing assemblies 350, which would affect the normal rotation of the bearing 352 and thus the normal movement of the RF cable assembly 340.

[0082] like Figure 9 As shown, the bearing assembly 350 includes a support base 351, and bearings 352 are movably connected to the upper ends of both ends of the support base 351. The two bearings 352 can support the RF cable assembly 340 above or below, ensuring that the RF cable assembly 340 can slide in the Y direction, making the movement of the RF cable assembly 340 more stable and smooth, and preventing it from flipping or tilting. This allows the test connector 343 of the RF cable assembly 340, i.e., the coaxial connector, to be accurately inserted into the test interface.

[0083] like Figures 10-11 The structure used to hold the product under test 600 is described in detail below:

[0084] In one embodiment, an upper cover plate 110 is fixed to the upper end of the base assembly 100, and a positioning unit 400 is fixed to the upper surface of the upper cover plate 110. The positioning unit 400 includes:

[0085] Positioning plate 410, with a fixed pin 420 and a movable pin 430 fixed on the top of the positioning plate 410;

[0086] The positioning plate 410 is provided with adjustment supports 440 on both sides. The adjustment support 440 includes a support body 441 and a slot 442 is provided on the support body 441. The support ears on both sides of the positioning plate 410 are inserted into the slot 442.

[0087] The support body 441 has an elongated hole 443, and Y-direction adjusting bolts 444 are threadedly connected to both sides of the slot 442. Z-direction adjusting bolts 445 are provided above the slot 442.

[0088] Specifically, two fixed pins 420, or positioning pins, are installed on the positioning plate 410 to position and limit the product under test. After the product under test is placed on the positioning plate 410, two movable pins 430, or hand pins, are manually inserted to position and limit the product under test in the same way.

[0089] However, due to tolerances in the machining of parts, the accumulated tolerances after the entire fixture is assembled may cause the coaxial connector of the RF cable assembly 340 to be incompatible with the test interface of the product under test. Therefore, by designing the positioning plate 410 for fixing the product under test as a structure that is adjustable in three directions (X, Y, and Z), and by providing an elongated hole 443 in the support body 441, adjustment in the X direction can be achieved. Adjustment in the Y direction can be achieved using the Y-axis adjusting bolt 444, and adjustment in the Z direction can be achieved using the Z-axis adjusting bolt 445.

[0090] With the cooperation of the above structures, the product under test can be precisely fixed in position, ensuring that the coaxial connector of the RF cable assembly 340 is accurately matched with the test interface of the product under test.

[0091] like Figure 12 As shown, a protective plate 500 is detachably connected to the side of the support leg 310 facing the test connector 343. The protective plate 500 is used to block the upper end of the RF cable assembly 340. The protective plate 500 includes a plate body 510 and foam 520. During transportation, in order to prevent the internal RF cable assembly 340 from sliding on the bearing assembly 350, the protective plate 500 is provided. The back of the protective plate 500 is covered with foam 520 and the protective plate 500 is fixed by two screws. This can block the RF cable assembly 340, thereby fixing the RF cable assembly 340 and preventing the internal components from shaking or colliding with each other.
