Abstract
The invention provides a metal spring leaf in an electronic product and a connecting structure adopting the metal spring leaf, which comprises a metal spring leaf and a PCB. The metal spring leaf comprises a spring leaf body with an elastic back bending structure; a contact end and a welding end are arranged at both ends of the spring leaf body; the welding end is near to the middle part of the spring leaf body; a hole groove is arranged on the PCB; and the metal spring leaf is arranged in the hole groove and welded on the PCB bard through the welding end. As the metal spring leaf has the elastic back bending structure, and the welding end is arranged at the middle part of the elastic back bending structure, the dimension of the metal spring leaf is greatly reduced, and the deformation of the metal spring leaf is reduced. As the metal spring leaf is arranged in the hole groove on the PCB, the exposed part of the metal spring leaf is reduced; therefore, the metal spring leaf can be elastically compressed in the hole groove, and the probability of deformation failure caused by unexpected collision of the metal spring leaf is reduced.
