[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0023] A touch module that is easy to repair, refer to Figure 1 and Figure 2, including a touch module body 10, the touch module body 10 includes a cover plate 11 and a sensing glass 12 which are arranged in sequence, the sensing glass 12 is bound with a touch IC for enabling the sensing glass 12 to have a touch function, the sensing glass 12 is also bound with an FPC 20, one end of the FPC 20 is bound to the sensing glass 12, and the other end of the FPC 20 is used to connect to the customer's mainboard.

[0024] Reference Figure 1 , because the existing FPC20 usually passes the electronic components 40 required by the SMT touch IC, and the electronic components 40 welded to the FPC20 will collide with the electronic components 40 in the subsequent assembly of the touch module, and the FPC20 needs to be bent, plugged, etc. during assembly, which is prone to collision. Therefore, one end of the FPC20 is externally connected to the PCB board 30, and the electronic components 40 required by the touch module body 10 are integrated on the PCB board 30.

[0025] Further, refer to Figure 1 One end of the FPC 20 is bound to the sensing glass 12 , and the other end of the FPC 20 is connected to the PCB board 30 . The end of the FPC 20 away from the sensing glass 12 is the interface end 21 , and the FPC 20 is connected to the PCB board 30 via the interface end 21 .

[0026] Reference Figure 1 A connector 50 for connection is provided between the FPC 20 and the PCB board 30 . The connector 50 is provided on the PCB board 30 . The interface end 21 of the FPC 20 is plugged into the connector 50 to realize electrical connection between the FPC 20 and the PCB board 30 .

[0027] Further, refer to Figure 1 The connector 50 is a ZIF connector, and the connector 50 connects the FPC 20 and the PCB board 30 in a ZIF manner, which has high reliability and low signal crosstalk.

[0028] Further, refer to Figure 1 The number of connectors 50 matches the number of interface terminals 21 of the FPC 20. In the present embodiment, the number of interface terminals 21 of the FPC 20 is two, and the number of corresponding connectors 50 on the PCB board 30 is also two. The two interface terminals 21 are correspondingly plugged into the two connectors 50.

[0029] Reference Figure 1A component area 31 is provided on the PCB board 30, and the electronic components 40 are bound to the component area 31. The PCB board 30 is electrically connected to the FPC 20, so that the electronic components 40 are connected to the FPC 20, which does not affect the filtering, voltage stabilization and electrostatic protection functions of the electronic components 40 on the corresponding circuits of the touch module body 10. When the electronic components 40 are damaged and need to be repaired, they can be replaced with a new PCB board 30 to be separated from the touch module body 10, which does not affect the normal use of the touch module body 10, thereby reducing unnecessary material loss.

[0030] Reference Figure 1 The PCB board 30 is provided with a pin end 32 for connecting to the customer's mainboard. The PCB board 30 is connected to the customer's mainboard through the pin end 32, thereby not affecting the connection between the FPC 20 and the customer's mainboard, thereby ensuring the normal use of the touch module body 10.
