Inside the housing 8, there are provided a PCBA main board (not shown in the figure), a touch control component and a key core module. The key core module includes a keycap component, an FPC 5 and a support iron plate 6 arranged from top to bottom. There is a conductive copper foil on the PCBA main board. A POGO elastic piece 501 (which warps downward) adapted to the conductive copper foil is welded on the FPC 5. The tail end of the POGO elastic piece 501 is in contact with the conductive copper foil to achieve electrical connection. In terms of electrical connection, the traditional conductive film is replaced with an FPC 5 (with weldable pads), the PIN end of the traditional conductive film is discarded, and the POGO elastic piece 501 is welded on the FPC 5. When connecting, just align and contact the POGO elastic piece 501 with the reserved copper foil on the PCBA main board to complete the signal transmission, and the disassembly and assembly are more convenient. When disassembling, just take out the key core module part upward.

[0021] Wherein, other components such as a battery may also be provided inside the housing 8, which will not be specifically elaborated here.

[0022] Further, the housing includes an upper shell and a bottom shell that are covered with each other. The upper shell and the bottom shell can be fixed by means such as screws or other fixing methods, which are not limited here.

[0023] Further, the FPC 5 is fixedly connected to the support iron plate 6, and the support iron plate 6 is attracted to the housing 8 through a magnetic attraction structure. The magnetic attraction structure includes a plurality of upper magnets 7 and lower magnets (not shown in the figure) that are correspondingly arranged and can attract each other. The upper magnets 7 and the lower magnets are respectively arranged inside the support iron plate 6 and the bottom shell. In terms of structure, a magnetic attraction structure is designed between the key core module and the housing 8. Through the magnetic attraction structure, the support iron plate 6 can be adsorbed on the bottom shell, so as to play a role in fixing the key core module. When the key core module needs to be replaced, just pick up the key core module forcefully, and then adsorb another new key core module to complete the replacement and connection.

[0031] In summary, the traditional conductive film is replaced with the FPC 5, and the POGO elastic sheets 501 are welded on the FPC 5. During connection, only the POGO elastic sheets 501 need to be aligned and contacted with the reserved copper foils of the PCBA main board. At the same time, a magnetic attraction structure is designed between the key core module and the housing 8. Through the magnetic attraction structure, the support iron plate can be adsorbed on the bottom case, thereby playing a role in fixing the key core module. When the key core module needs to be replaced, only the key core module needs to be pried up forcefully, and then another new key core module can be adsorbed to complete the replacement and connection. The assembly steps are simple and the key core is easier to disassemble and replace.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
