The existing spring structure application and contact method have the following problems:

[0004] (1) The existing springs occupy a large area on the board, which is not conducive to the development trend of miniaturization design of electronic equipment;

[0005] (2) The existing spring contact displacement deformation is an inclined displacement, and the contact portion will be inclined and displaced as the compression stroke increases, which poses a risk of unstable contact. Utility Model Content

[0006] An object of the present invention is to provide a spring connector to reduce the board area and improve the contact stability.

Therefore, the displacement deformation direction of the contact part is the vertical direction, and no tilting displacement occurs, and the contact stability is high. In addition, the movement of the contact part is limited by the first limiting part and the second limiting part, so excessive deformation can be avoided.
