  • Patent number: 8668527
    Abstract: An electrical connector includes an insulative housing and a number of upper and lower contacts fixed in the insulative housing. The insulative housing includes a base and a tongue portion extending from the base along a first direction. Each of the upper contacts includes a first planar soldering section situated adjacent to a bottom face of the base. Each of the lower contacts includes a second planar soldering section situated adjacent to the bottom face of the base. The lower contacts are assembled to the insulative housing along a second direction perpendicular to the first direction in order that the second planar soldering sections can be kept coplanar with the first planar soldering sections through controlling insertion depth of the lower contacts along the second direction.

  • Patent number: 7753738
    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).
