[0002] A circuit board can be called a printed circuit board or a printed circuit board. It has the characteristics of high wiring density, light weight, thin thickness and good flexibility. It is widely used in liquid crystal display screens. Its working principle is to convert the video signal in the format of VBO (V-by-One) interface protocol output by the display motherboard into a video signal in the format of EDP interface protocol, so that it can be received by the LCD screen timing control board using the EDP interface protocol, thereby controlling the data drive circuit of the LCD screen to turn on in time to light up the LCD screen.

[0003] The current circuit boards do not have a protective structure, so they are easily squeezed and damaged by external objects during early storage. The existing protective measure is to add flexible objects on the outside, but this method is more cumbersome to operate and the protective effect is general. Therefore, it has great limitations in actual use and there is room for improvement. Utility Model Content

Later disassembly is also achieved by squeezing the connecting column with force. The end face diameter of the connecting column is larger than the maximum diameter end of the connecting head. Therefore, when the protective plate is installed on the connecting column, it can be supported by the end face of the connecting column.

[0011] Preferably, the width of the protective plate is greater than or equal to the width of the main board, and the length of the protective plate is less than the length of the main board.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 4 The utility model provides a technical solution: a circuit board with a protective structure, including a main board 100, and a protective component is arranged outside the main board 100, and the protective component includes:

[0026] The connecting piece is connected through the mainboard 100, and both ends of the connecting piece are engaged with the protective piece. The protective piece is installed through the connecting piece, and can support the protective piece to ensure normal protection.

[0027] In this embodiment, preferably, the protective member is a protective plate 200 , and bottom grooves 100 a are formed at four corners of the protective plate 200 , and the bottom grooves 100 a are connected to the connecting member through-and-through.

[0028] In this embodiment, preferably, the connecting part includes a connecting column 101 that passes through the main board 100, and a truncated cone-shaped connecting head 101a is fixed at both ends of the connecting column 101. The connecting head 101a is connected through the through hole 200a, so as to realize the installation of the connecting column 101 and the protective plate 200. Deformation grooves 200b are opened around the through hole 200a. When the protective plate 200 is inserted into the connecting head 101a through the through hole 200a, the through hole 200a will be squeezed by the connecting head 101a. At this time, the deformation groove 200b is deformed to increase the inner diameter of the through hole 200a, so as to ensure normal tight installation. When disassembling later, the protective plate 200 can be detached from the connecting head 101a.

[0029] In this embodiment, preferably, the connecting column 101 is offset from the area passing through the main board 100, and the height is kept unchanged through deformation. The later disassembly is also achieved by squeezing the connecting column 101 with force. The end face diameter of the connecting column 101 is larger than the maximum diameter end of the connecting head 101a. Therefore, when the protective plate 200 is installed on the connecting column 101, it can be supported by the end face of the connecting column 101.

[0030] In this embodiment, preferably, the width of the protection plate 200 is greater than or equal to the width of the main board 100 , and the length of the protection plate 200 is less than the length of the main board 100 .

[0031] In the present embodiment, preferably, a bottom groove 100a is opened at the bottom of one side of the main board 100, and a side panel 102 is placed in the bottom groove 100a. The top of the side panel 102 vertically extends toward the top surface of the main board 100, and a resistor is arranged at the edge of the top surface of the main board 100. The resistor is located inside the side panel 102, and the resistor at the edge of the main board 100 is protected by the side panel 102, thereby improving the protection effect.

[0032] In this embodiment, preferably, a placement groove 102a is opened on the inner side surface of the side panel 102, and a double-sided tape 103 is bonded inside the placement groove 102a. The double-sided tape 103 is bonded to the inner top surface of the bottom groove 100a, thereby realizing rapid installation of the side panel 102 and the main board 100.
