Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a circuit board structure for a mechanical keyboard. Background Technology

[0002] A mechanical keyboard has an independent mechanical structure for each key, typically consisting of a keycap, a switch, one or more switches, and metal contacts. When a key is pressed, the force on the keycap is transmitted to the key stem, causing the key stem to press down, which in turn drives the switch contacts to close. After the switch contacts close, current can flow through the metal contacts to the metal contacts on the circuit board. Through the built-in key torque, the circuit board, as one of the core components of a mechanical keyboard, not only ensures the accurate transmission of key signals, but also improves the overall performance and durability of the mechanical keyboard through a reasonable layout and the selection of high-quality materials.

[0003] The following problems exist: In the design of mechanical keyboards, the layout compatibility of the circuit board is usually limited, which means that the interchangeability and universality between different keyboards are poor. In addition, the modularity of the circuit board is also relatively low, which may lead to more difficulties and limitations when repairing or upgrading. Inside the circuit board, the anti-interference ability of analog signals is often unsatisfactory, which may cause signal distortion or instability during keyboard use. At the same time, the manufacturing process of printed circuit boards has very high requirements, and any slight deviation or defect may affect the performance and reliability of the final product.

[0028] Reference Figure 1-5 The present invention provides an embodiment of a circuit board structure for a mechanical keyboard, comprising a first circuit board 1, a second circuit board 2 mounted on the top of the first circuit board 1, and rounded corners of both the first circuit board 1 and the second circuit board 2. This structure is not only aesthetically pleasing but also effectively protects the user's hands, preventing unnecessary injury from sharp corners during operation. The first circuit board 1 has multiple sets of through-holes 3, and the bottom of the second circuit board 2 is fixedly connected to multiple sets of circuit board components 4.

[0029] The outer wall of the circuit board component 4 is fitted with the inner wall of the socket 3. The cross-sectional dimension of the socket 3 is set to be larger than that of the circuit board component 4. This structure can effectively prevent unnecessary friction between the inner wall of the socket 3 and the outer wall of the circuit board component 4. Through this difference in size, it can be ensured that the socket 3 can smoothly accommodate the circuit board component 4, thereby avoiding any damage to the circuit board component 4 during insertion. This structure not only improves the convenience of assembly, but also ensures the reliability and service life of the circuit board. A special connector 5 is movably connected to one end of the outer wall of the second circuit board 2. An insulating block 6 is fixedly connected to the rear end of the special connector 5. The two ends of the special connector 5 are provided with through mounting holes 7. The rear end of the insulating block 6 is provided with an interface 8. Locking bolts 9 pass through the inner wall of the mounting holes 7.

[0030] Two sets of through-holes are provided at one corner of the first circuit board 1. The outer wall of the locking bolt 9 passes vertically upward through the holes and connects to the mounting holes 7 at both ends of the dedicated connector 5. The signal transmission between the first circuit board 1 and the second circuit board 2 is tightly connected through the dedicated connector 5, which can ensure the stability of the circuit board. Through innovative spatial layout and component design, the component layout space of the first circuit board 1 and the second circuit board 2 is optimized, thereby realizing more component arrangement in a limited space, and enabling the keyboard to be compatible with more layouts without replacing the circuit board.
