  • Patent number: 7549896
    Abstract: A receptacle connector (100) includes a metal shield (3) having the cover (31) and an opposite base (32). The cover (31) includes a pair of top lateral wings (312). The base includes a pair of bottom lateral wings (322) for mating with the respective top lateral wings (312). The top lateral wing (312) defines a first portion of a whole lateral wing board, while the bottom lateral wing (322) defines a second portion adapted to contribute towards completing the whole lateral wing board. Thus, the metal shield (3) is integrated by the cover (31) and the base (32), each of which is molded by a single sheet.

  • Patent number: 7473134
    Abstract: An electrical connector for connecting an electrical component to a printed circuit board through a flexible printed circuit comprises a shell defining a receiving space and a spring plate assembled in a bottom of the shell. The spring plate includes a main section extending in the longitudinal direction and against the bottom of the shell and contact sections extending from the two opposite sides of the main section. The main section defines a protrusion towards the receiving space in order to prevent the electrical component from overcompressing the spring plate.

  • Publication number: 20080305667
    Abstract: An audio jack comprises a set of contacts including a stationary contact (25) and a movable contact (23), and an anti-dust dome member (5). The anti-dust dome member (5) includes a conductive sheet (51) extending from a horizontal plate portion (250) of the stationary contact (25) to a lateral beam (235) of the movable contact (23), and a middle conductive dome sheet (52) below the conductive sheet (51). The conductive dome sheet (52) is constantly actuated to establish an electrical connection between the stationary contact (25) and the movable contact (23). Thus, even if dust is deposited on the anti-dust dome member (5) will have no effect on the electrical connection as established.

  • Patent number: 7402082
    Abstract: An electrical connector adapted for connecting a camera module to a printed circuit board via a flexible printed circuit comprises a shield and a spring plate. The shield includes a pair of opposite rear and front walls, a pair of left and right walls adjacent to the rear and front walls, and a flat bottom wall connecting the walls together to enclose a cavity for receiving the camera module. The spring plate is mounted on the bottom wall of the shell and has a main portion and a number of elastic arms extending outward from the two opposite sides of the main portion. Each of the front and rear wall of the shield includes an upright base extending upwardly from the bottom wall, a retaining section extending upwardly from the center of the upright base, and a pair of fastening sections extending from both sides of the retaining section and bending toward the receiving cavity.
