Abstract
A voice coil motor includes a lens retainer, a wire, and an elastic electrode member. The lens retainer includes an end portion. The wire wraps around the lens retainer and includes a first end and a second end. The elastic electrode member is metal and is mounted to the end portion. The elastic member includes a first elastic metal sheet and a second elastic metal sheet. The first elastic metal sheet includes a first electrode. The second elastic plate is physically separated from the first elastic sheet and includes a second electrode. The first end and the second end are respectively soldered to the first electrode and the second electrode.
Claims9
A voice coil motor, comprising:
- a lens retainer having a first end portion;
- a wire having a first end and a second end, the wire being wound around the lens retainer;
- and
- an elastic electrode member being mounted to the first end portion, the elastic member comprising a first elastic metal plate and a second elastic metal plate, the first elastic plate comprising a first electrode, the second elastic plate being physically separated from the first elastic metal plate and comprising a second electrode;
- wherein the first end and the second end are respectively soldered to the first electrode and the second electrode;
- wherein the first elastic plate comprises a first section, a second section, and a third section, the third section is substantially perpendicularly to the first section and distant from the second section, the second section is substantially perpendicularly connected to the first section, a first inner corner is positioned at intersection of the first section and the second section, a second inner corner is positioned at intersection of the first section and the third section, the first elastic plate comprises a first arm portion extending from the first section adjacent to the first inner corner toward the second inner corner along a direction substantially parallel to the first section, a crescent-shaped first contact portion extending from an end of the first arm portion, and a second arm portion extending from the third section adjacent to the second inner corner along a direction parallel to the third section, the second arm portion extends beyond the third section, the first elastic plate comprises a crescent-shaped second contact portion extending from an end of the second arm portion, and a crescent-shaped first slot defined in center of and extending through the second contact portion, leaving the first electrode.
