Abstract

The invention discloses a micro-driving motor and a lower spring for the same. A lower elastic piece component comprises the lower spring for the micro-driving motor which comprises two mutually insulated elastic piece bodies and electrifying pins vertically extending down from one side of each elastic piece body. The bottom end of each electrifying pin protrudingly extends perpendicular to the corresponding electrifying pin and away from the lower elastic piece component to form a fixed pin. The micro-driving motor comprises a shell and the lower elastic piece component, wherein the shell consists of an upper cover and a base, and the lower elastic piece component is fixed into the shell. The micro-driving motor and the lower spring for the same have the advantages that the fixed pins of the lower elastic component are parallel and attached to a welding face of a circuit board, and welding can be quickly completed by a simple, reliable and efficient welding mode while welding quality is easy to guarantee.

Description

technical field [0001] The invention belongs to the technical field of micro-drive motors, and in particular relates to a lower spring of a micro-drive motor and a micro-drive motor made of the shrapnel. Background technique [0002] The existing lens driving device is also called a micro-driving motor. There is a certain gap between its conductive terminal and the circuit board, and the connection planes are perpendicular to each other. The disadvantage is that there is a certain gap between the conductive terminal of the lens driving device and the circuit board, and the connection planes are perpendicular to each other, which is not conducive to soldering, the soldering time is longer, and it is easy to cause false soldering. The welding time is long, the lens driving device is easily heated, and it is easy to cause defects at high temperatures. Contents of the invention [0003] The object of the present invention is to provide a micro drive motor lower spring with be...
