Patent number: 11597627Abstract: 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.Type: GrantFiled: April 15, 2021Date of Patent: March 7, 2023Assignee: USI Science and Technology (Shenzhen) Co., Ltd.Inventors: Yun-Kai Yu, Chang-Cheng Lin, Kuo-Kuang Liu, Der-Jiuh Jan

Patent number: 8437095Abstract: 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.Type: GrantFiled: October 19, 2011Date of Patent: May 7, 2013Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Fang-Sheng Lin, Yun-Kai Yu

Publication number: 20130003010Abstract: 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.Type: ApplicationFiled: August 5, 2011Publication date: January 3, 2013Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventor: YUN-KAI YU
