Description

Technical Field

[0001] This utility model relates to the field of radio frequency coaxial switch testing technology, specifically a highly adaptable radio frequency coaxial switch testing fixture. Background Technology

[0002] As a key component in radio frequency (RF) systems, coaxial switches are primarily used to switch signal transmission paths. The core purpose of testing is to verify their electrical performance, reliability, and environmental adaptability, ensuring stable operation in scenarios such as communication, radar, and microwave equipment.

[0003] When testing RF coaxial switches, it is usually necessary to connect wires to the ports of the RF coaxial switch and plug and unplug them multiple times. Each time, one hand must hold the RF coaxial switch and the other hand connects the wires. This requires the operation of both hands at the same time, and the wires are prone to bending and damage due to uneven force. Utility Model Content

[0004] The purpose of this invention is to provide a highly adaptable RF coaxial switch test fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a highly adaptable RF coaxial switch test fixture, comprising:

[0006] Mount the base plate, two clamping plates, and the moving mechanism;

[0007] The two clamping plates are arranged one above the other, with the lower clamping plate fixedly connected to the mounting base plate and the upper clamping plate connected to the moving mechanism.

[0008] Both clamping plates have embedded slots inside their facing sidewalls, and both clamping plates have arc-shaped through slots inside their facing sidewalls.

[0009] Preferably, connecting plates are welded to opposite sides of the two clamping plates, and the connecting plates on the upper and lower sides are connected to the mounting base plate and the moving mechanism by screws.

[0010] Preferably, the moving mechanism includes an n-shaped frame, with a pull rod movably inserted into the middle of the upper end of the n-shaped frame, and a base plate connected to the bottom end of the pull rod. The base plate is connected to the upper connecting plate by screws.

[0011] Preferably, a groove is provided on the outer wall of the pull rod, the groove is parallel to the axis of the pull rod, and a slider matching the groove is provided on the n-shaped frame.

[0012] Preferably, a compression spring is connected between the upper end of the n-shaped frame and the upper surface of the base plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This solution can hold the housing of the RF coaxial switch in place. When making wiring connections, the switch is perpendicular (or nearly perpendicular) to the clamping plate of this solution. Due to the restriction of the clamping plate, the RF coaxial switch is fixed, and wiring can be made with one hand. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Example 1:

[0024] Please see Figure 1-5 This utility model provides a technical solution: a highly adaptable radio frequency coaxial switch test fixture, comprising: a mounting base plate 1, two clamping plates 6, and a moving mechanism;

[0025] The two clamping plates 6 are arranged vertically, with the lower clamping plate 6 fixedly connected to the mounting base plate 1 and the upper clamping plate 6 connected to the moving mechanism; both clamping plates 6 have embedded slots 8 inside their facing sidewalls and arc-shaped through slots 9 inside their facing sidewalls.

[0026] Analysis of the above content: When in use, the end plate of the RF coaxial switch is embedded in the embedded slot 8, and the side wall of the RF coaxial switch is exposed through the arc through the slot 9, which facilitates wiring. When wiring, the RF coaxial switch is restricted by the embedded slot 8 of the upper and lower side clamps 6, making it difficult for the RF coaxial switch to move laterally. Therefore, the connection and wiring can be performed with one hand.

[0027] To prevent the left end of the RF coaxial switch from sagging, a shim can be placed on the left side of the upper surface of the mounting base plate 1 to support the lower left side of the RF coaxial switch.

[0028] Example 2:

[0029] Please see Figure 1-5 Based on Embodiment 1, this utility model provides a technical solution: connecting plates 7 are welded to the opposite sides of the two clamping plates 6, and the connecting plates 7 on the upper and lower sides are connected to the mounting base plate 1 and the moving mechanism by screws.

[0030] Analysis of the above content: This solution is mainly applicable to Figure 3 , 4 If other types of radio frequency coaxial switches are required to be adapted, the screws on the clamp plate 6 and the connecting plate 7 can be removed to replace the clamp plate 6 and the connecting plate 7.

[0031] Example 3:

[0032] Please see Figure 1-5 This utility model provides a technical solution based on Embodiment 1: the moving mechanism includes an n-shaped frame 2, a pull rod 3 is movably inserted into the middle of the upper end of the n-shaped frame 2, a base plate 5 is connected to the bottom end of the pull rod 3, and the base plate 5 is connected to the upper connecting plate 7 by screws.

[0033] Analysis of the above content: The pull rod 3 can lift the base plate 5, thereby lifting the upper connecting plate 7 and the upper clamping plate 6 based on the base plate 5, which facilitates the clamping and disassembly of the RF coaxial switch.

[0034] Example 4:

[0035] Please see Figure 1-5 Based on Embodiment 3, this utility model provides a technical solution: a sliding groove is provided on the outer wall of the pull rod 3, the sliding groove is parallel to the axis of the pull rod 3, and a slider matching the sliding groove is provided on the n-shaped frame 2.

[0036] Analysis of the above content: Due to the restriction of the slider and the slide, the tie rod 3, the base plate 5, the upper connecting plate 7 and the upper clamping plate 6 can only move longitudinally and cannot rotate relative to the n-shaped frame 2. In this way, the upper clamping plate 6 and the lower clamping plate 6 remain in correspondence.

[0037] Example 5:

[0038] Please see Figure 1-5 Based on Embodiment 3, this utility model provides a technical solution: a compression spring 4 is connected between the upper end of the n-shaped frame 2 and the upper surface of the base plate 5.

[0039] Analysis of the above content: The compression spring 4 elastically presses the base plate 5, the upper connecting plate 7, and the upper clamping plate 6 from the top. Here, the compression spring 4 only prevents the base plate 5, the upper connecting plate 7, and the upper clamping plate 6 from rising. Since the RF coaxial switch connection wiring usually only involves lateral force, the compression spring 4 is sufficient to press the base plate 5, the upper connecting plate 7, and the upper clamping plate 6. In order to further ensure that the base plate 5, the upper connecting plate 7, and the upper clamping plate 6 are prevented from rising, screws connected to the pull rod 3 can be set on the n-shaped frame 2 to lock the pull rod 3 and prevent it from rising.

[0040] Furthermore, the innovative aspects of this solution will be explained.

[0041] Double-clamp embedded fixing structure: The RF coaxial switch housing is clamped by the embedded slots 8 of the upper and lower clamps, and the wiring port is exposed by the arc-shaped through slot 9, forming a vertical limit to prevent the housing from shaking when wiring.

[0042] Adjustable moving mechanism: The lifting structure is composed of an n-shaped frame 2, a pull rod 3 and a compression spring 4. The rotation of the clamping plate is limited by the sliding block design, which realizes quick clamping and disassembly and is suitable for switches of different sizes.

[0043] Elastic clamping design: The clamping spring 4 provides continuous downward pressure, combined with the screw locking function to prevent the clamp from loosening during testing and enhance the fixation stability.

[0044] Specifically, a comparison of relevant test data and practical application data for this solution.

[0045]

[0046] Data Description

[0047] Single-hand wiring operation time: The tester repeated the wiring plugging and unplugging operation 100 times and recorded the completion time. Existing technology requires both hands to adjust the switch position, while this solution allows direct plugging and unplugging due to the clamp limit. The time reduction mainly comes from the simplification of operation steps.

[0048] Wiring damage rate: In 500 consecutive tests, the existing technology caused the wiring to bend and be damaged 25 times due to uneven hand force, while this solution only caused damage 10 times, proving that the limiting structure can reduce the impact of external force on the wiring.

[0049] Lateral displacement after fixing: A 5N lateral force is applied to the switch, and the displacement is measured by a displacement sensor. Existing technologies suffer from significant displacement due to the lack of a fixing device; this solution significantly reduces displacement by using clamping plates and slots to limit it.

[0050] Data Validity Statement

[0051] Test environment: constant temperature 25℃, humidity 50% RH, to avoid environmental factors from interfering with the operational accuracy.

[0052] Sample size: Each test was repeated more than 100 times, and the mean and standard deviation were calculated using statistical methods, with a data confidence level of 95%.

[0053] Comparison of consistency: The test objects are the same model of RF coaxial switch, and the wiring type and insertion / removal force are kept consistent to ensure data comparability.
