Abstract

Disclosed are a lens driving device, a camera device and an electronic apparatus equipped with the lens driving device. When the lens driving device is mounted on the circuit board, the power supply terminal is less likely to fall off from the base. The lens driving device of the present disclosure includes a base, a lens support, and a driving mechanism that drives the lens support in the optical axial direction. The base is integrally provided with a power supply terminal mounted on an external circuit board and used for supplying power to the driving mechanism. A fall-off preventive portion is formed in at least a part of a contact portion that is in contact with the base on the power supply terminal.

First claim

What is claimed is:

1. A lens driving device comprising:
a base;
a lens support; and
a driving mechanism for driving the lens support along an optical axial direction, wherein
the base is integrally provided with a power supply terminal mounted on an external circuit board and used for supplying power to the driving mechanism, and
a fall-off preventive portion is formed in at least a part of a contact portion that is in contact with the base on the power supply terminal, wherein
the power supply terminal has a vertical portion extending forward from the rear of the optical axial direction, and a horizontal portion extending from a front end of the vertical portion in a direction orthogonal to the optical axis and exposed from a front surface of the base,
the vertical portion has an external connection portion exposed from the base and mounted on the circuit board, and an internal structural portion inside the base and in contact with the base,
the fall-off preventive portion is a forward-facing surface provided in the internal structural portion.

2. The lens driving device according to claim 1 , wherein
the forward-facing surface is provided in a side groove of the power supply terminal which is formed by cutting off a part of the vertical portion.

3. The lens driving device according to claim 1 , wherein
the forward-facing surface is provided on a protrusion which is formed to protrude from the vertical portion of the power supply terminal.

4. The lens driving device according to claim 1 , wherein
the forward-facing surface is provided in a through-hole formed the power supply terminal through the vertical portion.

5. The lens driving device according to claim 1 , wherein
the forward-facing surface is formed along a second contour line that is changed in orientation such that a first contour line extending from the rear of the vertical portion of the power supply terminal extends inward.

6. A camera device comprising the lens driving device of claim 1 .

7. An electronic apparatus comprising the camera device of claim 6 .

8. A lens driving device comprising:
a base;
a lens support; and
a driving mechanism for driving the lens support along an optical axial direction, wherein
the base is integrally provided with a power supply terminal mounted on an external circuit board and used for supplying power to the driving mechanism, and
a fall-off preventive portion is formed in at least a part of a contact portion that is in contact with the base on the power supply terminal, wherein
the power supply terminal has a vertical portion extending forward from the rear of the optical axial direction, and a horizontal portion extending from a front end of the vertical portion in a direction orthogonal to the optical axis and exposed from a front surface of the base,
the horizontal portion has an inclined portion which extends obliquely rearward from a portion not connected to the vertical portion and is in contact with the base,
the fall-off preventive portion is a forward-facing surface provided in the inclined portion.

9. A camera device comprising the lens driving device of claim 8 .

10. An electronic apparatus comprising the camera device of claim 9 .
