Coil and spring connecting structure, voice coil motor, photographic device and electronic product

Abstract

The invention discloses a coil and spring connecting structure, a voice coil motor, a photographic device and an electronic product. According to the technical scheme, the coil and spring connecting structure comprises a carrier, a coil and an upper spring connected to the carrier, wherein the coil surrounds the side wall of the carrier, the upper spring comprises two upper spring sub-parts whichare symmetrically arranged, each upper spring sub-part comprises an inner connecting part, an outer connecting part and an upper cantilever, a riveting column penetrating through a riveting hole is integrally formed on the carrier, the carrier is provided with two wire winding grooves allowing wire ends at the two ends of the coil to penetrate through and be clamped in, wire winding parts corresponding to the wire winding grooves are integrally formed on the two inner connecting parts, and the wire winding parts are provided with fixing grooves allowing the wire ends at the ends of the coil tobe wound conveniently. According to the invention, the electric welding positions of the wire head and the wire winding part are conveniently and effectively determined, and the coil tensioning effect is achieved through reverse wire pulling, so that the coil loosening and falling conditions are effectively avoided, and the product quality and the yield are high.

Description

technical field [0001] The invention relates to the field of photographic equipment, in particular to a coil and spring connection structure, a voice coil motor, a photographic device and electronic products. Background technique [0002] The existing voice coil motor structure generally includes a base, a carrier, a bracket, an upper spring, a lower spring, and a casing. The lens is installed on the carrier, and the upper spring is hot riveted to the bracket, and the lower spring is fixed to the base. [0003] The existing carrier is generally provided with a winding post, and the wire at the end of the coil is wound around the winding post, and the upper spring abuts against the winding post, and is connected by conductive glue or soldering to achieve conduction between the coil and the upper spring. [0004] The above-mentioned coil and the upper spring are connected in a complicated way, and need to go through multiple processes, and it is not easy to tension the coil. ...

AI Technical Summary

Problems solved by technology

[0004] The connection between the above coil and the upper spring is complex and requires multiple processes, and it is not easy to tension the coil

[0005] There is also a problem that the thread end of the coil is directly connected to the upper spring, which may easily lead to unstable working position, poor consistency of coil position, and poor welding quality.
