[0002] In the field of electromagnetic compatibility (EMC), EMC testing of electronic products is a crucial step to ensure that the products will not interfere with other electronic devices during actual use and are also resistant to external electromagnetic interference. However, when conducting EMC performance testing, it is often difficult to securely fix non-floor-standing samples. This lack of stable support can lead to deviations in test results and affect the reproducibility of test results, thereby affecting the accurate assessment of the sample's EMC performance. Traditional EMC testing methods often have some limitations in this regard, especially when fixing and supporting electronic products of different sizes and thicknesses for testing. They are difficult to adapt to electronic products of different sizes and shapes, resulting in the need to frequently replace or adjust fixtures during testing, increasing the complexity and time cost of testing.

The connecting section is connected to the transverse limiting groove through a hand-held quick-screw screw. The limiting section is used to clamp the upper edge of the transverse support plate, and the supporting section is used to support or limit the non-floor-standing electronic product.

[0007] Preferably, the transverse support plate is provided with two rows of transverse limiting grooves, and one or more wire clamping grooves are provided between the two rows of transverse limiting grooves.

[0016] In order to make the purpose, principle and structure of the present invention more clear, it is further described below with reference to the accompanying drawings and specific embodiments.

[0017] See also Figure 1 、 Figure 2 This embodiment 1 provides an electromagnetic compatibility detection auxiliary device for fixing floor-type samples, including two transverse support plates 1 of the same size, each transverse support plate 1 having four transverse limit grooves 5 arranged parallel to each other in the upper and lower directions, and each transverse support plate 1 is connected to a guide sleeve 3 at both ends, and the guide sleeve 3 is a hollow cylindrical shape, and each guide sleeve 3 is provided with two hand-held quick-tightening screws 8 vertically arranged on the upper and lower outer sides.

[0018] Two conduits 2 are vertically arranged on both sides of the device. The conduits 2 serve as the longitudinal supports of the device. The lower ends of the conduits 2 are connected to the support plate 6. The bottom of the support plate 6 is fixedly connected to a universal wheel. The universal wheel can be configured with a locking wheel function to move the device for easy use. The conduits 2 pass through the guide sleeves 3 at both ends of the transverse support plate 1 and can move up and down. They are fixed by hand-held quick-tightening screws 8 so that the two transverse support plates 1 are in a relatively parallel position. The guide sleeves 3 are the user's hand-operated parts. The conduits 2, guide sleeves 3 and hand-held quick-tightening screws 8 can cooperate to fix the specific position of the transverse support plate 1. At the same time, the conduits 2 are marked with a scale, and the distance from the transverse support plate 1 to the ground can be directly observed.

[0019] Each transverse support plate 1 of this device is provided with two claws, namely an upper claw 4 and a lower claw 10. Each claw comprises a central connecting section, a limiting section connected to the top of the connecting section, and a supporting section connected to the bottom of the connecting section. Each section is well fixedly connected. The limiting section, connecting section, and supporting end are connected perpendicularly to each other, forming a "Z"-shaped structure. The claw is connected to the transverse limiting groove 5 by a hand-held quick-tightening screw 8 provided on the connecting section. In conjunction with the hand-held quick-tightening screw 8, the claw can move horizontally left and right within the transverse limiting groove 5 to fix the sample. The limiting section of the upper claw is used to clamp the upper edge of the transverse support plate, and the supporting section is used to support or limit the non-floor-standing electronic product. The lower claw 10 located on the lower transverse support plate 1 is larger than the upper claw 4 located on the upper transverse support plate 1. The supporting section of the lower claw 10 is longer than the supporting section of the upper claw 4. The upper claw 4 is used to fix the upper surface of the sample, and the lower claw 10 is used to fix and support the sample. The upper clamping jaw 4 and the lower clamping jaw 10 are used in conjunction with the handheld quick-tightening screw 8. When the upper clamping jaw 4 and the lower clamping jaw 10 work together, the sample can be fixed to ensure the stability of the sample. The number of clamping jaws used can be selected as 2, 4, 6, etc. according to actual needs.

[0020] See also Figure 2 The transverse support plates 1 are provided with two. The upper transverse support plate 1 has a cable slot 9 on the right side of the back. The cable slot 9 is located in the middle of the transverse limit slot and is used to store, classify or fix cables and wires of the sample. Depending on the specific situation, different inner diameter sizes can be designed to accommodate cables and wires of different diameters, and they can be fixed at any position on the front and back plates of the transverse support plate 1.

[0021] See also Figure 3 , the working principle of this device is:

[0022] 1. If the test item requires a certain height between the sample and the ground, adjust the guide sleeve 3 on the guide tube 2 to adjust the horizontal support plate 1 below the device to the appropriate position, and then tighten it with the hand-held quick-tighten screw 8.

[0023] 2. According to the thickness of the sample, select the appropriate number of upper jaws 4 and lower jaws 10. According to the width of the sample, fix the lower jaw 10 into the limit groove of the horizontal support plate 1 below the device and tighten it with the hand-held quick-tightening screw 8.

[0024] 3. Place the sample on the tightened lower jaw 10.

[0025] 4. Adjust the height of the horizontal support plate 1 above the device according to the height of the sample, and secure the upper clamping jaw 4 of the appropriate size to it, ensuring that the upper clamping jaw 4 is in close contact with the upper surface of the sample. Tighten the upper clamping jaw 4 with the hand-held quick-tightening screw 8 to ensure the stability of the sample.

[0026] 5. There should be enough space between the two horizontal support plates 1 to facilitate heat dissipation of the sample and the connection of cables on the back of the sample.

[0027] 6. The use of the transverse limiting groove 5, the guide tube 2, and the guide sleeve 3 can meet the needs of fixing samples of different sizes.

[0028] 7. The cable trough 9 can effectively protect the cables from bending and damage, and also protect the structure connecting the sample and the cable from deformation, ensuring the normal power supply and communication of the sample. In addition, the reasonable planning and placement of the cables is also conducive to the test layout and the reproducibility of the test results.

[0029] 8. If the sample is small and needs to be hung, after determining the sample hanging height and specific position, fix the hand-held quick-turn screw 8 in the appropriate area of ​​the horizontal limit groove 5 and hang the sample directly on the hand-held quick-turn screw 8.

[0030] 9. The bottom of the support plate 6 is fixedly connected to a universal wheel, which is conducive to the flexible movement of the entire device and also facilitates the convenient use of the device.

[0031] 10. The transverse support plate 1 is installed on the conduit 2, and a scale mark is set on the conduit 2. The transverse support plate 1 is adjusted in height and tightened on the conduit 2 through the guide sleeve 3 and the hand-held quick-tightening screw 8, and the specific height positioning can be visually checked.

[0032] The above description is only a specific implementation method of this utility model, but the protection scope of this utility model is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by this utility model, can make equivalent substitutions or changes based on the technical solutions and new concepts of this utility model, which should be covered by the protection scope of this utility model.
