Abstract
A spring leaf structure is used to electrically connect a circuit board and an electronic element, and comprises a fixed connecting part, a connecting part, a contact part and two supporting parts which are molded integrally. The lower surface of the fixed connecting part is welded with the circuit board, the contact part is contacted with the electronic element, and the fixed connecting part and the contact part are connected at the two ends of the connecting part respectively; the two supporting parts are arranged on the fixed connecting part and are formed by extending upwards two relative side edges of the fixed connecting part close to the connecting part, and the heights of the two supporting parts are higher than the height of the connecting part and are lower than the height of the contact part. When the spring leaf is applied overlarge force to be distorted excessively, the supporting parts at the left and right sides of the spring leaf structure support a force applying object directly, so that all the forces are applied to the supporting parts at the left and right sides; and because the supporting parts are directly connected with the fixed connecting part of the spring leaf structure as one, the force capable of being born by the supporting parts is much larger than the force capable of being born by a deformation part of the spring leaf structure, thereby achieving the purpose of protecting the spring leaf structure.
