Description

TECHNICAL FIELD

[0001] The utility model relates to the field of charging spring piece, concretely to a spring piece structure in earphone box. BACKGROUND

[0002] The charging spring piece in the earphone box is a key component for connecting the earphone and the charging box for power transmission, which is made of a material with good conductivity and elasticity, and is designed with a specific curvature to ensure close contact with the earphone charging contact. When the earphone is put into the charging box, the charging spring piece automatically adheres to the contact, and the power is transmitted from the charging box to the earphone battery through the circuit to realize the charging function.

[0003] The existing charging spring piece in the earphone box is mostly of an integral bending structure, and the bending butt joint is usually non-contact type without direct connection. For example, the publication number "CN222030065U" discloses a spring piece structure for a Bluetooth earphone box, wherein the butt joint of the side plate 12 and the upper guard plate 14 is a non-contact structure. Although this processing technology can improve the production efficiency of the charging spring piece, it still has the problem of unstable charging spring piece structure. During long-term use, the self-stress or external force factors of the charging spring piece can easily cause deformation and damage of the charging spring piece, reducing the service life of the charging spring piece.

[0015] Further, both sides of the elastic plate are bent to form bending ears, and the upper inner sides of the front side plate and the back side plate are bent to form folding edges.

[0017] Further, the inner sides of the front side plate and the back side plate and opposite to the limiting plate are bent to form limiting sheets, and the inner sides of the limiting plate and the limiting sheets abut to limit the position of the limiting plate.

[0018] By adopting the above technical scheme, the displacement range of the contact part is further limited, the overall stability and safety of the elastic sheet structure are improved, and the contact part can be prevented from excessive deformation or damage caused by external force during charging.

[0019] Further, one side of the front side plate and the back side plate is formed with a triangular ear piece, and the ear piece is fixedly connected with a plug on one side of the bottom plate.

[0020] By adopting the above technical scheme, a convenient fixing and connecting method is provided for the elastic sheet structure, so that the elastic sheet structure can be easily installed into the earphone box, and connected with the external circuit through the plug.

[0021] Further, the three groups of pins are arranged in a triangular structure, and the pins are formed with inner grooves and through holes.

[0022] By adopting the above technical scheme, the stability and torsion resistance of the pins are improved, and the elastic sheet structure is more reliable and stable when connecting external circuits, can resist external impact and vibration, and prevent charging failure caused by loosening or falling of the pins.

[0023] Further, the bottom plate and the elastic part are made of phosphor copper material, and the elastic sheet is integrally punched and bent.
