摘要:
An electronic device (100) includes a metal shell (1) having a number of walls (11,12) and an antenna unit (3). The metal wall has an interior space (17) defined therebetween, at least one recess (110) defined on one of the wall (11), and a mating member (111) disposed around the recess and extending into the interior space. The antenna unit is received in the recess and has a locating portion (36) extending from a side portion thereof and pivotably engaging with the mating member. When the antenna unit is rotated from a closed position to an opening position, another side portion of the antenna unit extends outward from the recess.

A dipole antenna assembly (100, 200) includes a dipole antenna (10, 30) and a feeding element (20, 40) connecting with the dipole antenna. The dipole antenna includes a radiation portion (12, 32), a ground portion (13, 33) and a circuit (14, 34). The feeding element includes a central conductor (21, 41) soldered on the radiation portion at a first position, and a shielding layer (23, 43) soldered on the ground portion at a second position. The circuit includes one end connecting with the radiation portion at the first position, and another end connecting with the ground position at the second position for impedance matching.

A dual-band dipole antenna (100) includes a ground radiating portion (2), a signal radiating portion (3) and a feed wire (1). The feed wire (1) has a ground portion (12) connected to the ground radiating portion (2), and a core conduct (11) connected to the signal radiating portion (3). The signal radiating portion (3) has a first branch (31), a second branch (32) having a same length and a same width as the first branch (31), and a middle portion (33) connecting the first branch (31) and the second branch (32) at connecting points. Each of the first branch (31) and the second branch (32) has a first radiating length (D1) extending from the connecting point and a second radiating length (D2) extending from the connecting point.

An optical-electrical connector assembly comprises a housing, a printed circuit board received in the housing and including a number of converting elements, a lens member, a ferrule aligned with the lens member and having a resisting portion, an integrated securing member, a coiled spring received in the securing member, and an optical cable having a number of optical fibers. The ferrule has a first engaging portion and a second engaging portion engaged with the housing. The coiled spring is compressed between the resisting portion and the first engaging portion.

An optical-electrical connector (100) includes a housing (11), a circuit board (3) received in the housing and having a transducer for bidirectional optical-electrical signal conversion, a lens member (42) mounted on the circuit board, a ferrule (43) receiving a number of optical channels and having a resisting face (431), a supporting portion (51) having a base wall (511), and a resilient member. The ferrule is situated behind the lens member within the housing and aligned with the lens member along a front-to-back direction. The resilient member is permanently maintained an invariable compressed state between the base wall and the resisting face of the ferrule to provide an invariable forward resilient force to the ferrule for fixing the ferrule to the lens member, when the optical-electrical connector is used and unused.

An electrical connector system includes 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 includes 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) has a third wire (73) and a fourth wire (75) that are physically separated from and electrically connected to opposite ends of the second wire (53).
