One end of the spring 3 is connected to the metal sheet 2, and the other end is arched. The arched part of the spring 3 is elastic and can extend outside the shell 1 to discharge static electricity.

[0027] like Figure 3 As shown, both ends of the metal sheet 2 are connected with metal pads 4, and the metal pads 4 are connected to the spring 3.
