[0030] This utility model provides a novel electromyography (EMG) electrode assembly adapted to the wrist, including a wristband 1. The top of the wristband 1 has several sets of mounting slots 10. A PCB circuit board 2 is installed inside the mounting slots 10. A set of mechanisms for limiting the PCB circuit board is provided on the inner walls of both sides of the mounting slots 10. An insulating electrode holder 6 is connected and installed on one side of the PCB circuit board 2. A set of electrode connection slots 7 are provided on the surface of the insulating electrode holder 6. A metal dry electrode 8 is installed inside the electrode connection slots 7.

[0031] The mechanism for limiting the PCB circuit board includes a set of limiting plates 11, and the PCB circuit board 2 is installed between the limiting plates 11. Due to the design of the limiting plates 11, when installing the PCB circuit board 2, since both the limiting plates 11 and the wristband 1 are made of silicone, the user can forcefully pull the mounting slot 10 to install the PCB circuit board 2 between the limiting plates 11, thus limiting the PCB circuit board 2. The operation is very simple. If the PCB circuit board 2 needs to be replaced, simply pull the wristband 1 again and pull the PCB circuit board 2 out from inside the limiting plates 11. This indirectly brings convenience to the user in installation and disassembly, and the design greatly increases practicality.

[0032] The electrode connection groove 7 has a connection hole 9 at its inner bottom end.

[0033] The PCB circuit board 2 has a set of spring pins 3 installed at its top, and one end of the spring pins 3 is connected to the metal dry electrode 8 through the connecting hole 9.

[0034] The PCB circuit board 2 has a set of through holes 4 on its surface.

[0035] The bottom end of the insulating electrode holder 6 is equipped with a set of connectors 5, and the connectors 5 extend to the outside through the through hole 4.

[0036] The wristband 1 and the limiting plate 11 are both made of silicone.

[0037] The edges of the metal dry electrodes 8 are all rounded. By rounding the edges of the metal dry electrodes 8, the user can effectively avoid pressure marks and discomfort on the skin of the wrist when wearing them for a long time, thus indirectly improving comfort. It is very convenient.

[0038] The specific usage and function of this embodiment are as follows:

[0039] Before installation and use, the user needs to inspect the internal components or structure of the electrode assembly. After inspection, normal use is possible. First, when installing the PCB circuit board 2, since both the limiting plate 11 and the wristband 1 are made of silicone, the user can pull the mounting slot 10 to install the PCB circuit board 2 between the limiting plate 11, thus limiting the PCB circuit board 2. The operation is very simple. If the PCB circuit board 2 needs to be replaced, simply pull the wristband 1 again and pull the PCB circuit board 2 out from inside the limiting plate 11. This indirectly brings convenience to the user's installation and disassembly, and the design greatly increases practicality. After that, the wristband can be worn on the wrist for normal use. The rounded corners of the metal dry electrode 8 effectively prevent pressure marks and discomfort on the skin of the wrist when the user wears it for a long time, indirectly improving comfort. It is very simple. If you need to use it again, just repeat the above operation.
