Description

Technical Field

[0001] This utility model relates to the field of communication equipment testing technology, and in particular to a radiation testing device. Background Technology

[0002] In today's digital wave, the network information industry is experiencing rapid development, with a surge of 5G wireless terminal products. Simultaneously, user standards for product experience are rising and becoming increasingly stringent. In the field of electromagnetic compatibility (EMC) testing, radiated spurious emission (RSE) testing plays a crucial role. It is primarily used to assess unintended electromagnetic radiation generated by wireless communication devices or transmitting equipment outside their normal operating frequency range. Because this type of radiation is not generated within the device's designated operating frequency, it is called "spurious emission."

[0003] In the 3G / 4G era, terminal products used relatively low signal frequency bands and had fewer antennas. The test fixtures used at that time had a symmetrical structure, and by placing coupling plates at the top and bottom of the product, the electromagnetic radiation of the product could be effectively detected. Under the technological conditions at the time, this adequately met the basic testing requirements.

[0004] However, the advent of the 5G era has brought entirely new challenges. One of the most significant features of 5G products is their multi-antenna configuration, which greatly enhances product performance but also places higher demands on electromagnetic radiation testing. Existing testing fixtures are no longer adequate for this task, failing to accurately and effectively test the electromagnetic radiation from the multiple antennas of 5G products. Given the complex and ever-changing electromagnetic radiation conditions of these multiple antennas, comprehensive coverage and precise detection are difficult to achieve. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a radiation testing device to solve the problem that current communication equipment testing fixtures cannot flexibly test multi-directional electromagnetic radiation.

[0029] Example 1

[0030] Combination Figures 1 to 3 As shown, the radiation testing equipment of this utility model is schematically displayed, including a base 10, a support plate 20, a first mounting plate 40 and multiple coupling plates 30.

[0031] The base 10 is provided with a support plate 20 and a first mounting plate 40, and the base 10 serves a supporting function. The first mounting plate 40 is located on one side of the support plate 20 and the two are perpendicular to each other. The first mounting plate 40 is detachably provided with a coupling plate 30. The support plate 20 is provided with multiple connection holes 21 for connecting the device under test. The device under test can be placed on different connection holes 21, so that the relative position between the device under test and the coupling plate 30 on the first mounting plate 40 can be changed to flexibly change the test conditions and meet various test requirements.

[0032] like Figure 2 The coupling plate 30 on the first mounting plate 40 can test the electromagnetic radiation on the side of the device under test. Furthermore, coupling plates 30 are arranged above and / or below the support plate 20, and these coupling plates 30 can test the electromagnetic radiation above and / or below the device under test, thus enabling multi-directional testing of the electromagnetic radiation of the device under test. By adjusting the position and number of coupling plates 30, all radiation surfaces of the device under test can be fully covered, ensuring the accuracy and comprehensiveness of the test data.

[0033] like Figure 1 The first mounting plate 40 is provided with a slide rail 42 arranged perpendicularly to the support plate 20. The end of the support plate 20 is slidably connected to the slide rail 42, allowing the support plate 20 to move on the slide rail 42. This adjusts the distance between the device under test and the coupling plate 30 above and / or below the support plate 20, enabling more dimensional adjustments to the test conditions. The design of the slide rail 42 enhances the flexibility and adjustability of the device, ensuring accurate data acquisition under different test scenarios and improving test efficiency. Furthermore, the slide rail 42 is equipped with scale markings for accurate measurement and recording of the movement distance of the support plate 20, ensuring consistency and repeatability of test conditions for each test.

[0034] The first mounting plate 40 has multiple first mounting holes 41 arranged in a matrix. The coupling plate 30 is detachably connected to the first mounting holes 41. The matrix arrangement of the first mounting holes 41 provides the basic conditions for easily quantifying and adjusting the position of the coupling plate 30, making the relative position between the coupling plate 30 and the device under test on the first mounting plate 40 easier to reproduce, allowing testers to conduct multiple reproducible test experiments. The matrix arrangement design not only improves installation efficiency but also ensures the accuracy and consistency of test data. Through this structure, testers can quickly adjust and calibrate the equipment to adapt to different test requirements, further improving the reliability and efficiency of the experiment.

[0035] The radiation testing equipment also includes a second mounting plate 50 located above the support plate 20 and a third mounting plate 60 located below the support plate 20. The end of the second mounting plate 50 is slidably connected to a slide rail 42. A coupling plate 30 is detachably mounted on both the second and third mounting plates 50 and 60. When both the second and third mounting plates 50 and 60 are equipped with coupling plates 30, adjusting the position of the support plate 20 on the slide rail 42 can adjust the distance between the product under test and the coupling plate 30 on the third mounting plate 60. Conversely, when the support plate 20 remains in its current position, adjusting the position of the second mounting plate 50 on the slide rail 42 can adjust the distance between the product under test and the coupling plate 30 on the second mounting plate 50. This multi-level radiation testing ensures detailed test results and multi-dimensional data acquisition, further enhancing the comprehensiveness and reliability of the test. Through this multi-level and multi-dimensional testing layout, the equipment can accurately capture the electromagnetic radiation characteristics of the product under test at different positions and angles, providing detailed data support for product optimization and improvement, and ensuring its electromagnetic compatibility and safety in various application environments.

[0036] More specifically, the second mounting plate 50 has a plurality of second mounting holes 51 arranged in a matrix. The coupling plate 30 is detachably connected to the second mounting holes 51. The plurality of second mounting holes 51 arranged in a matrix provides the basic conditions for the coupling plate 30 to easily and quantitatively adjust its position, making the relative position between the coupling plate 30 on the second mounting plate 50 and the device under test easier to reproduce, allowing testers to conduct multiple reproducible test experiments. Similarly, the third mounting plate 60 has a plurality of third mounting holes 61 arranged in a matrix. The coupling plate 30 is detachably connected to the third mounting holes 61. The plurality of third mounting holes 61 arranged in a matrix provides the basic conditions for the coupling plate 30 to easily and quantitatively adjust its position, making the relative position between the coupling plate 30 on the third mounting plate 60 and the device under test easier to reproduce, allowing testers to conduct multiple reproducible test experiments.

[0037] Combination Figure 2 and Figure 3 A slide table 421 is slidably mounted on the slide rail 42, allowing the slide table 421 to slide back and forth on the slide rail 42. The slide table 421 has a guide rail 421a arranged perpendicular to the slide rail 42. The support plate 20 is slidably connected to the guide rail 421a. The slide table 421 can drive the guide rail 421a and the support plate 20 to slide together relative to the slide rail 42. The support plate 20 can also slide relative to the guide rail 421a, and the guide rail 421a and the slide rail 42 are perpendicular to each other. The support plate 20 can extend from the base 10 to slide relative to the guide rail 421a, so that the tester can install the device under test on the support plate 20, improving the user experience. Moreover, when testing the device under test, a large number of cables and data acquisition devices need to be connected to the device under test. The support plate 20, which can slide relative to the guide rail 421a, makes it easier for the tester to place and organize the cables and data acquisition devices. The support plate 20 has a slot 22 on its side, which allows the tester to pull the support plate 20 by hand to drive the support plate 20 to slide on the guide rail 421a.

[0038] Example 2

[0039] The difference between this embodiment and Embodiment 1 is that the radiation testing equipment includes a swing assembly, which includes a first swing component 431 and a second swing component 432 that are rotatably connected. The first swing component 431 is detachably connected to the first mounting hole 41, and the second swing component 432 is connected to the coupling plate 30. This allows the swing angle of the coupling plate 30 on the first mounting plate 40 to be adjusted, and the angle between the coupling plate 30 and the device under test to be adjusted. This increases the testable dimensions, improves the flexibility and coverage of the test, ensures accurate acquisition of radiation data at different angles, and further optimizes the performance of the product under test.

[0040] In summary, the base 10 is provided with a first mounting plate 40 and a support plate 20. The connection holes 21 on the support plate 20 can be used to install the device under test (DUT). A coupling plate 30 is provided on the first mounting plate 40 located on one side of the support plate 20. The first mounting plate 40 is perpendicular to the support plate 20, so that the coupling plate 30 can test the electromagnetic radiation on the side of the DUT. The support plate 20 is provided above and / or below it, and the coupling plates 30 are arranged facing it. These coupling plates 30 can test the electromagnetic radiation above and / or below the DUT, realizing multi-directional electromagnetic radiation testing of the DUT. By connecting and installing with different connection holes 21, the relative position between the DUT and the coupling plate 30 can be adjusted, and the test conditions can be flexibly adjusted to meet the product test requirements.
