摘要:
The electrical connector system comprises a substrate (1) connected to PHY side and an electrical connector (3) mounted on the substrate (1), a transformer (5) and a common mode filter (7). The electrical connector (3) is used to mate with a cable assembly and so forms a Cable side. The transformer (5) further comprises a first wire (51) having two opposite ends electrically connected to the PHY side and a second wire (53) having two opposite ends. The common mode filter (7) having a third wire (73) and a fourth wire (75) that are physically separated from the second wire (53). The third wire (73) has an end electrically connected to one end of the second wire (53) and an opposite end electrically connected to the Cable side. The fourth wire (75) has an end electrically connected to the opposite end of the second wire (53) and an opposite end electrically connected to the Cable side.

An electronic apparatus includes a main circuit board and a printed antenna secured to the main circuit board. The main circuit board has a grounding trace and a feed trace. The printed antenna includes an insulative base having a number of conductive traces deposited thereon in order to form a grounding portion and a radiating portion separated from each other. The grounding and the radiating portions have first and second conductive pads electrically and mechanically connecting the grounding trace and the feed trace, respectively. As a result, traditional coaxial cables used for connecting the printed antenna and the main circuit board are omitted.

An optoelectronic connector includes a cover, a circuit board mounted in the cover, and an optical module assembled to the circuit board. The optical module includes a lens module having a U-shaped receiving space, a ferrule mounted on an end of an optical waveguide, and a locking bolt releasably inserted through the lens module and assembled into the ferrule. The ferrule has two opposite side walls and adapted to be at least partly received within the receiving space. The locking bolt is configured for securely mounting the ferrule and lens module together.
