LENS BARREL, CAMERA, IMAGING APPARATUS, AND COIL COMPONENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240161974 titled 'LENS BARREL, CAMERA, IMAGING APPARATUS, AND COIL COMPONENT

Simplified Explanation

The patent application describes a lens barrel with a printed-wiring board and a coil component mounted on the board. The coil component includes winding and core portions, with two winding core portions having a gap between them. The number of turns around each core portion differs, with the first core portion closer to the optical axis.

• The lens barrel includes a printed-wiring board located on the outside of the lens.
• A coil component with winding and core portions is mounted on the printed-wiring board.
• The core portion of the coil component consists of two winding core portions with a gap between them.
• The number of turns of the winding portion around each core portion varies, with the first core portion closer to the optical axis.

Original Abstract Submitted

a lens barrel includes a printed-wiring board located on an outside of a lens as viewed in a first direction in which an optical axis of the lens extends and including a first principal surface on an object side, and a coil component including a winding portion and a core portion and mounted on the first principal surface of the printed-wiring board. the core portion includes first and second winding core portions with a gap therebetween in an axial direction in which the first and second winding core portions extend, around which the winding portion is wound. a number of turns of the winding portion around the first winding core portion is smaller than a number of turns of the winding portion around the second winding core portion. the first winding core portion is located on a side closer to an optical axis than the second winding core portion.
