[0024] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of methods and systems consistent with some aspects of the present invention as detailed in the appended claims.

[0025] References Figure 1-3 As shown, the present invention provides a high-speed signal transmission device, including: a fixed bracket 1, a high-speed cable 2 and an adjustable fixing device 3, wherein the fixed bracket 1 is provided with a limiting hole 5 of a cable connector 4 of a preset size, one end of the high-speed cable 2 is connected to the cable connector 4, and the other end is connected to a board connector 6, the board connector 6 is connected to a board 7, the fixing device 3 is arranged in the fixed bracket 1, and corresponds to the size of a test board 8, and the fixing device 3 fixes the test board 8.

[0026] According to the high-speed signal transmission device of the embodiment of the present invention, by using a high-speed cable to connect the cable connector and the board connector, the device can effectively support the stable transmission of high-speed signals. High-speed cables usually have lower signal attenuation and wider bandwidth, which are suitable for high-frequency, high-speed data transmission, thereby improving the signal transmission efficiency of the overall system; by using a high-speed cable to connect the cable connector and the board connector, the device can effectively support the stable transmission of high-speed signals. High-speed cables usually have lower signal attenuation and wider bandwidth, which are suitable for high-frequency, high-speed data transmission, thereby improving the signal transmission efficiency of the overall system; the adjustable fixture design enables the device to be compatible with test boards of different sizes, increasing the versatility and flexibility of the system. Whether it is a test board of standard size or a non-standard test board for a specific project, it can be adapted by adjusting the fixture, reducing the cost and time of customizing special fixtures for different test boards.

[0027] In the embodiment of the present invention, a preset number of fixing grooves or clamps are provided in the fixing bracket 1, and the fixing grooves or clamps are used to fix the fixing device 3, and the fixing device 3 is used to fix the connector 9 of the test board.

[0028] Optionally, four fixing grooves 10 are provided in the fixing bracket 1, and each fixing groove 10 is used to fix the fixing device 3. Through the adjustable fixing device 3 and a preset number of fixing grooves or clamps, the device can flexibly adapt to test boards 8 of different sizes and specifications, thereby improving the versatility and configurability of the device.

[0029] In an embodiment of the present invention, the connector 9 of the test board is fixed to the fixing bracket 1 based on the fastening component 11, and the fastening component 11 includes thread fastening or spring locking. Figure 2 As shown, when the fastening component 11 is threaded fastening, the fastening component 11 includes a screw 111 and a nut 112. By using the fastening component 11 (such as threaded fastening or spring locking) to fix the connector 9 of the test board on the fixing bracket 1, the stability and reliability of the high-speed signal transmission process are ensured. This fastening method can effectively resist external factors such as vibration and impact, and reduce signal attenuation and interference.

[0030] In the embodiment of the present invention, a positioning hole 12 is provided in the fixing bracket 1 , and the test board 8 passes through the positioning hole 12 based on a positioning member to be positioned on the fixing bracket 1 .

[0031] In the embodiment of the present invention, the limiting holes 5 are arranged on both sides of the fixing bracket 1 in a queue form, the cable connector 4 is inserted into the limiting holes 5 and connected to the connector 9 of the test board, and a step is provided at the contact portion between the limiting holes 5 and the cable connector 4. The step can prevent the cable connector 4 from being pressed and not easily sliding down. The step is provided at the contact portion between the limiting holes 5 and the cable connector 4, and this design helps to reduce the shaking and deviation of the cable connector 4 during the insertion process, thereby reducing the impedance and loss during the signal transmission process.

[0032] The cable connector 4 corresponds to the limiting hole 5 .

[0033] In the embodiment of the present invention, the fixing bracket 1 is made of a high-strength, low-impedance metal material, such as aluminum alloy or stainless steel, to ensure the stability of the fixing bracket 1 and minimize the impact on signal transmission.

[0034] In the embodiment of the present invention, the outer skin of the high-speed cable 2 is made of polytetrafluoroethylene with low loss and high insulation performance, and the inner core is made of copper alloy or silver alloy with low resistivity and high conductivity. The material characteristics jointly optimize the performance of signal transmission, ensuring efficient and stable transmission of high-speed signals. Among them, differential signal transmission technology can be used, combined with impedance matching and shielding design, to effectively reduce signal interference and attenuation, and improve the integrity and accuracy of signal transmission.

[0035] In other words, differential signal transmission transmits data by sending two signals with opposite phases at the same time, which can effectively suppress common mode noise and improve the signal's anti-interference ability. This technology is particularly suitable for high-speed data transmission and can significantly improve the integrity and accuracy of signal transmission; in signal transmission systems, impedance matching is an important factor in ensuring signal integrity. By reasonably designing the impedance of high-speed cables to match the impedance of other parts of the transmission system (such as connectors, circuit boards, etc.), signal reflection and distortion can be reduced and signal quality can be improved; in order to further reduce external electromagnetic interference, high-speed cables usually adopt a multi-layer shielding design. These shielding layers can effectively isolate the interference of external electromagnetic fields on internal signals, while reducing the impact of signal radiation on the external environment.

[0036] In an embodiment of the present invention, one end of the high-speed cable 2 is connected to the cable connector 4, and the other end is connected to the board connector 6, that is, the cable connector 4 and the board connector 6 are processed by precision machining and electroplating to reduce the flatness difference between the board connector 6 and the test board 8 caused by mechanical installation, thereby ensuring good contact and signal transmission between the board 7 and the test board 8.
