The invention of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The invention is selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various inventions with various modifications suitable for specific purposes.

[0020] See also Figures 1 to 4In this embodiment, a high-frequency and high-speed circuit board is provided, including a circuit cavity 1 and a circuit board body 2. A base 11 is symmetrically installed at the bottom of the circuit cavity 1, and the circuit board body 2 is installed on the upper end surface of the base 11 by a clamping method. Through holes are symmetrically opened on the left and right side walls of the circuit cavity 1, and L-shaped plates 12 are arranged in the through holes. Fixing grooves are symmetrically opened on the front and rear side walls in the through holes, and spring rods 13 are installed in the fixing grooves. A limit plate 14 is installed on the other end of the spring rod 13, and the limit plate 14 is connected to the through hole by a sliding fit. When working, high-frequency amplifier components and high-speed relays are arranged on the circuit board body 2 to ensure high-frequency and high-speed transmission of data. The L-shaped plate 12 limits and fixes the top of the circuit board body 2, and the spring rod 13 drives the limit plate 14 to move inward to limit and fix the L-shaped plate 12, ensuring the fixing effect of the circuit board. Compared with bolt fixing, it is convenient to disassemble the circuit board body 2 without the help of tools, saving time and effort.

[0021] A fixing cavity 15 is installed at the bottom of the circuit cavity 1, and a limiting spring 16 is symmetrically installed on the left and right side walls of the fixing cavity 15. A first slider 17 is installed at the other end of the limiting spring 16, and an L-shaped plate 12 is installed on the upper end surface of the first slider 17. When working, the limiting spring 16 drives the first slider 17 to move inward to further ensure the fixing effect of the L-shaped plate 12.

[0022] A first clamping head 18 is installed at the inner end of the first slider 17, and the left and right side walls of the circuit cavity 1 are symmetrically provided with matching clamping grooves. When working, the first clamping head 18 is clamped into the clamping groove, thereby limiting and fixing the first slider 17, thereby improving the overall stability of the device.

[0023] A placement groove is provided at the bottom of the circuit cavity 1, and an adjusting screw 19 is rotatably installed on the rear end face of the placement groove through a bearing, a handle 21 is installed on the front end face of the adjusting screw 19, an adjusting slider is installed on the outer wall of the adjusting screw 19, a bottom plate is installed on the upper end face of the adjusting slider, and a camera 22 is installed on the upper end face of the bottom plate. When working, the handle 21 is rotated to drive the adjusting screw 19 to rotate, so that the camera 22 moves back and forth, thereby photographing the bottom of the circuit board body 2. When the circuit board body 2 fails, it can be repaired without disassembling the circuit board, thereby improving the maintenance efficiency.

[0024] A display screen 23 is installed on the front end surface of the circuit cavity 1. The display screen 23 is electrically connected to the camera 22. When working, the display screen 23 displays the circuit board situation photographed by the camera 22.

[0025] The upper surface of the bottom plate is installed with a lighting lamp 24, and the inner end of the lighting lamp 24 is arranged with a camera 22. When working, the lighting lamp 24 is used for lighting processing to prevent the camera 22 from taking a dark and unclear picture, which makes it difficult for the staff to see clearly and make a correct diagnosis.

[0026] During specific operation, high-frequency amplifier components and high-speed relays are arranged on the circuit board body 2 to ensure high-frequency and high-speed data transmission. The L-shaped plate 12 limits and fixes the top of the circuit board body 2, and the spring rod 13 drives the limit plate 14 to move inward to limit and fix the L-shaped plate 12, ensuring the fixing effect of the circuit board. Compared with bolt fixing, it is convenient to disassemble the circuit board body 2 without the help of tools, saving time and effort.
