[0022] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] In existing technologies, radio frequency radiation immunity testing requires placing at least 1 meter of cables, signal lines, and control lines connected to the device under test (DUT) within a uniform interference signal field. When there are many cables, signal lines, and control lines in the DUT, it is impossible to fix all cables, signal lines, and control lines within the uniform interference signal field, resulting in inaccurate test results.

[0024] Therefore, such as Figures 1 to 4 As shown, an embodiment of this utility model provides a test platform for radio frequency radiation immunity testing to solve the above-mentioned technical problems.

[0025] Specifically, a test platform for a radio frequency radiation immunity test includes a platform 1, a support member 2, and a fixing device 3. The platform 1 has a wire receiving groove 11 on one adjacent side, extending along the length of the platform 1. The support member 2 is positioned on the surface of the platform 1 adjacent to the ground, supporting the platform 1. When the platform 1 is positioned above the support member 2, the distance between the upper surface of the platform 1 and the ground is 0.8 meters. The fixing device 3 is located within the wire receiving groove 11, with its height not exceeding the upper surface of the platform 1. The fixing device 3 is used to fix the connection lines of the test device (here, connection lines refer to cables, signal lines, control lines, or other lines electrically connected to the test device). Thus, when there are many cables, signal lines, and control lines of the test device, the fixing device 3 confines them within the wire receiving groove 11, ensuring that all cables, signal lines, and control lines are within a uniform interference signal field, avoiding any impact on the test results.

[0026] In some embodiments, such as Figure 1 and Figure 2 As shown, for cases where the diameter of the cable, signal line, and control line is small, the fixing device 3 includes a body 31 and multiple fixing parts 32 connected to the body 31. The multiple fixing parts 32 are arranged at intervals on the body 31. The cable, signal line, and control line can be wound around the fixing parts 32. The width of the body 31 is equal to the width of the wire receiving groove 11. When the fixing device 3 is placed in the wire receiving groove 11, the body 31 can be snapped into the wire receiving groove 11, and the wire receiving groove 11 has a fixing effect on the body 31.

[0027] In some embodiments, such as Figure 3 andFigure 4 As shown, for the case that the diameters of the cables, signal lines and control lines are large, the fixing device 3 comprises a bottom plate 33 and two side plates 34, the two side plates 34 are respectively connected to the two sides of the bottom plate 33, the bottom plate 33 and the two side plates 34 form a U shape, the distance between the two ends of the two side plates 34 away from the bottom plate 33 is greater than the distance between the two ends of the two side plates 34 adjacent to the bottom plate 33, when the fixing device 3 is placed in the wire accommodating groove 11, the U-shaped mouth of the fixing device 3 faces the wire accommodating groove 11, the cables, signal lines and control lines are limited in the fixing device 3, and the fixing device 3 and the wire accommodating groove 11 form a space.

[0028] In some embodiments, in order to fix the fixing device 3 in the wire accommodating groove 11, the distance between the two ends of the two side plates 34 away from the bottom plate 33 is equal to the width of the wire accommodating groove 11, when the fixing device 3 is placed in the wire accommodating groove 11, the U-shaped mouth of the fixing device 3 faces the wire accommodating groove 11, and the two side plates 34 can be clamped in the wire accommodating groove 11.

[0029] In some embodiments, in order to facilitate the placement and fixation of the cables, signal lines and control lines, the length of the table plate 1 is not less than 1 meter.

[0030] In some embodiments, in order to test safety, the material of the table plate 1 is preferably an insulating material.

[0031] The above description is only the preferred embodiment of the present application, and is not used to limit the present application, it should be pointed out that, for the ordinary skilled in the art, without departing from the technical principles of the present application, can make a number of improvements and modifications, these improvements and modifications should also be regarded as the protection scope of the present application.
