20100277800 | LENS PROTECTION STRUCTURE FOR MINIATURE LENS FOCUSING MECHANISM - A lens protection structure for miniature lens focusing mechanism includes a lens, a lens driving mechanism and a protective glass. The lens focuses light on an image sensor to thereby form an image thereon. The lens driving mechanism includes a hollow structure, in which the lens is received and driven to linearly move in an optical axis direction, so as to focus light on the image sensor. The protective glass is provided at a lens inlet of the lens driving mechanism, and is fixedly held to the lens driving mechanism by a plurality of forward projected stoppers formed at the lens inlet. With the protective glass located in front of the lens, the lens is protected against dust and damage by external force when being assembled to form a half-finished product or stored as a half-finished product. | 11-04-2010 |

20120105986 | HOUSING STRUCTURE FOR MINIATURE LENS FOCUS MODULE - A housing structure for miniature lens focus module has a top portion formed into a stepped structure, that is, the housing has a size-reduced topmost portion relative to the rest rear portion thereof and has a shoulder portion formed therein, so that a plate-shaped spring element for holding a lens holder can be directly connected to the shoulder portion in the housing to keep away from the topmost portion of the housing by a predetermined distance and define an operation space between the shoulder portion and the topmost portion, allowing the lens holder and accordingly a lens held thereto to axially linearly move within the operation space to focus light. The spacer provided in the prior art lens focus module can be omitted to reduce the cost and the assembling procedures of the lens focus module. | 05-03-2012 |
20120120510 | MAGNET HOLDING STRUCTURE OF AUTO-FOCUS MODULE - A magnet holding structure of auto-focus module includes an outer frame for holding four magnets to four inner wall surfaces of the outer frame; a lens holder for holding a lens thereto and being assembled to the outer frame via at least one spring member; and a winding fitted around the lens holder for driving the lens holder to axially move forward or rearward to focus automatically. The outer frame is provided at each of four inner corners with an inverted L-shaped plate extending downward from a top of the outer frame to locate between the lens holder and the winding, so as to face toward four spaces respectively existing between two adjacent magnets outside the winding. With these arrangements, the electromagnetic field produced by the winding can have enhanced magnetic efficiency and increased driving force at the corners of the winding to achieve the purpose of power saving. | 05-17-2012 |
20120224841 | ANTI-SHAKE STRUCTURE FOR AUTO-FOCUS MODULAR - An anti-shake structure for auto-focus module includes an auto-focus module for driving a lens to move forward and rearward in a light incident path, i.e. in z-axis direction, so that the lens focuses light on an image sensor; a frame for holding the auto-focus module therein; a lens suspender with a compensation lens arranged thereon being connected to a plurality of suspension wires while the latter are connected at respective another end to the top cover plate of the frame, so that the compensation lens is correspondingly suspended in the frame in the light incident path and located behind the lens; and a shake compensation driving unit for driving the lens suspender to move horizontally along x-axis or y-axis direction, so as to compensate any image shift caused by hand shaking. | 09-06-2012 |
20130293969 | MINIATURE LENS AUTO-FOCUSING STRUCTURE - A miniature lens auto-focusing structure includes a housing having a top plate; a base plate connectable to the housing to define an inner space between them; a lens module wound around by a coil; and at least one spring member holding and suspending the lens module in the inner space without causing the lens module to contact with the top plate and the base plate. With these arrangements, the spring member is not in a pre-tensioning state when the miniature lens auto-focusing structure is in a non-actuated state. Therefore, the miniature lens auto-focusing structure requires less actuating current and has smaller lens tilt angle than the conventional VCM auto-focusing structure, and can be manufactured at further reduced component cost. | 11-07-2013 |
20140049847 | LENS FOCUSING DEVICE - A lens focusing device includes a lens holder for holding a lens therein, a base, and an electrically conductive spring member elastically connected to between the lens holder and the base. The base is provided on a side wall with two terminal recesses, in which two connecting terminals are disposed. The connecting terminals respectively include a first terminal portion forward extended along a light axis to electrically connect to the spring member, a second terminal portion rearward extended along the light axis, and a connecting portion located between the first and the second terminal portion. The spring member is further electrically connected to two ends of a winding wound around the lens holder, so that external electric current can be supplied to the winding via the connecting terminals and the spring member for driving the lens holder to move relative to the base along the light axis. | 02-20-2014 |
20140049848 | LENS FOCUSING DEVICE - A lens focusing device includes a lens holder, a winding fitted around the lens holder, and an outer case enclosing the lens holder therein. The outer case includes an outer wall portion, and multiple inner wall portions connected to the outer wall portion via multiple connecting portions. The inner wall portions are located between the lens holder and the winding, and respectively include an inner surface, an outer surface, and a first and a second side surface. The lens holder is formed on an outer face with confining areas, each of which includes a main surface and a first and a second raised side surface respectively facing against the inner surface and the first and second side surfaces, so that the inner wall portions are limited to move relative to the lens holder only within the confining areas. Therefore, the lens focusing device is impact-resistant and undue-twisting protected. | 02-20-2014 |

The conductive parts have proximity ends separated and staggered to each other. An insulating base is formed by injection molding and encapsulates the conductive member wherein the conductive pins, the interconnection part and the contacts are exposed out of the insulating base. The interconnection part is cut and then a spring member is mounted to the insulating base and electrically connected to the conductive pins through the contacts. The present invention can solve the problem of difficulty in assembling conductive pins and connecting the spring member for the insulating base. The conductive member is arranged within the insulating base such that plastic material can be saved, the flatness, the stability and the anti-damage ability of base can be enhanced. | 02-12-2015 |
