[0002] A wireless keyboard is a keyboard that is not directly connected to the computer through a physical connection. It transmits input information to a special receiver through infrared or radio waves. The difference between wireless keyboards and wired keyboards lies mainly in the connection method and portability. Wireless keyboards do not need to be connected to the computer through physical cables, but communicate through wireless signals, so they are more portable and flexible. Users can move the keyboard freely within a certain range without worrying about the constraints and restrictions of cables. In addition, wireless keyboards have the advantages of being easy to carry and easy to connect to multiple devices.

[0040] Working principle: when you want to separate the main keyboard 1 from the numeric keypad 2, pull the numeric keypad 2 to the right, and the numeric keypad 2 drives the connecting seat 9 to slide to the right in the connecting groove 3. At this time, the connecting seat 9 drives the data transmission component to move to the right, and the connecting pins 16 are squeezed in the horizontal direction of the pin groove 7. Under the action of the arc surface at the bottom of the connecting pins 16, they slide upward, and squeeze the limiting spring 14 through the limiting cylinder 15, so as to slide into the limiting groove 13, so as to conveniently separate the numeric keypad 2 from the main keyboard 1, and there will be no data connection line falling out. On the other hand, when you want to travel with only the main keyboard 1, you can remove the magnetic nameplate 21 on the numeric keypad 2 and slide the wireless receiver 19 to the right to disengage the wireless receiver 19 from the rectangular block 18. Then insert the left side of the wireless receiver 19 into the limit block 8, and place the magnetic nameplate 21 inside the connecting slot 3. A magnetic force is generated between the nameplate magnet 22 and the limit magnet 5 to fix the magnetic nameplate 21 on the main keyboard 1, so that you can conveniently carry the main keyboard 1 when traveling.
