[0026] The assembly structure of the first spring piece 12 and the auxiliary spring piece 14 includes at least the following two methods:

[0027] The first one is that the lower end surface of the first elastic sheet 12 contacts the upper end surface of the auxiliary elastic sheet 14 . In this state, the elasticity of the first elastic sheet 12 is the strongest.

[0028] In the second mode, a gap is formed between the lower end surface of the first elastic piece 12 and the upper end surface of the auxiliary elastic piece 14. In this state, the elasticity of the first elastic piece 12 is slightly weaker than that of the first mode.

[0029] Which of the above two methods to use can be selected according to actual usage requirements.

A conductive convex 120 is also formed on the conductive portion 122, and the conductive convex 120 is in contact with the static piece terminal 2, so as to further improve the stability of the conductive connection. In addition, the static piece terminal 2 has a clearance opening 21 for the first raised portion 121 of the first spring piece 12 to pass through, so that the static piece terminal 2 and the first spring piece 12 can be assembled more compactly and more stably.

[0031] The auxiliary spring piece 14 is formed by stamping and bending upward along the lower end surface of the first main body portion 11, and the auxiliary spring piece 14 has a second raised portion 141, which is located below the first raised portion 121, wherein the second raised portion 141 is in contact with the first raised portion 121, or a gap is formed between the second raised portion 141 and the first raised portion 121.
