  • Patent number: 11597627
    Abstract: A wire retracting device includes a base having a platform, a limiting board disposed on the base, a cover including a top surface and a side wall, a slide block slidably disposed on a sliding area, and a transmission wire disposed in an accommodating space formed between the cover and the base. An annular wall is arranged on the platform, and has a limiting portion that has a first stop portion and a second stop portion respectively formed on two sides thereof. A gap, in which the cover is limited to being movable, is formed between the limiting board and the platform. The top surface has a grooved opening, and a lever is arranged on an inner edge thereof. The side wall is disposed along an edge of the top surface. The sliding area is formed between the inner edge of the grooved opening and the annular wall.

  • Patent number: 8760570
    Abstract: A camera module includes a lens module having a lens holder having a top surface, a bottom surface, a side surface and a through hole through the top surface and the bottom surface, a liquid crystal lens, wires, and a driving unit, a PCB, and solder balls. The liquid crystal lens is received in the through hole. The wires are arranged on the top surface and the side surface. One end of each wire is electrically connected to the liquid crystal lens, and the other end includes a solder terminal on the side surface. The driving unit drives the liquid crystal lens. The PCB includes a rigid print circuit board supporting the lens holder and a flexible print circuit board having a free end bent toward the side surface. The solder balls interconnect the solder terminals and the free end.

  • Patent number: 8437095
    Abstract: A compact lens module includes a lens seat, a lens group, a first and a second circuit boards. The lens seat includes a top surface, a bottom surface opposite to the top surface, and a first side surface connecting the top surface to the bottom surface. The lens seat defines a receiving space extending through the top surface and the bottom surface, and a receiving groove on the first side wall. The lens group is received in the receiving space. The first circuit board is mounted on the bottom surface of the lens seat, and holds an image sensor aligned with the lens group. The second circuit board is received in the receiving groove. The second circuit board holds a lens drive circuit and electrically connected with the lens group and the first circuit board.

  • Publication number: 20130003010
    Abstract: A camera module includes a lens module, a circuit board and solder balls. The lens module includes a lens holder, a liquid crystal lens, and wires. The lens holder includes an outer surface, a first end portion, and a second end portion at opposite sides of the lens holder. The lens holder defines wire grooves in the first and second end portions and the outer surface. The liquid crystal lens is received in the first end portion. The wires are formed on the first end portion The outer surface and the second end portion in the wire grooves are electrically connected to the liquid crystal lens. Each wire includes a solder terminal. The circuit board includes solder pads each corresponding to the solder terminal The solder balls each interconnect the solder pad and the corresponding solder terminal and are formed by low-temperature solder paste composed of tin and bismuth.
