Abstract:
A wireless communications device for IP address negotiations is provided and comprises a wireless module, a connection device, and a processing unit. The wireless module provides wireless communications from and to a service network. The connection device is coupled to the terminal device. The processing unit is coupled to the connection device and the wireless module, receiving an IP address request message from the terminal device via the connection device, and requests an IP address and a DNS address from the service network via the wireless module in response to an IP address request message from the terminal device. Also, the processing unit determines whether allocated IP address and DNS address have been received from the service network, and sends a rejection message to the terminal device to trigger the terminal device to resend the IP address request message in response to determining that the allocated IP address and DNS address have not been received from the service network.

Abstract:
A high speed cable connector (1) includes a cover (10), a base (80) and a cable assembly (30) mounted between the cover and the base. The cable assembly includes a cable (42) consisting of a plurality of lines (44). Each line has a signal pair (47, 48) and a ground conductor (492). The signal pair includes a pair of upper and lower signal conductors (472, 482). The ground conductors are soldered to shielding plates (50). The shielding plates are soldered to top and bottom faces of a rear end of a printed circuit board (PCB) (62). The upper and lower signal conductors of each signal pair are soldered to the top and bottom faces of the rear end of the PCB, respectively, and located between two neighboring shielding plates, whereby cross-talk and interference between two neighboring signal pairs can be effectively suppressed and reduced. The PCB has a front end electrically connecting with contacts (662) for electrically engaging with a complementary connector. The cable connector further has latches (88) for latching with the complementary connector, and a pull tab (82) for releasing the latching when the pull tab is pulled.

Abstract:
An I/O card (10) includes an internal PC board (26) attached to the frame means (12, 18) which extend along the edges of the PC board (26). A top panel (60) and a bottom panel (40) sandwich the frame (12, 18) and its associated PC board (26) therebetween. A socket connector (34) is positioned at the rear end of the I/O card (10). Oppositely, a specifically shaped and dimensioned opening (21) extends through the front wall (14) of the frame (12) in a front-to-end direction whereby a projecting section (29) of the PC board (26) extends into the opening (21). Two rows of traces (31) are staggeringly positioned respectively on opposite surfaces of the PC board (26) along the projecting section (29) so that when a card edge cable connector (70) is adapted to be snugly inserted into the opening (21) of the I/O card (10), the projecting section (29) of the PC board (26) is electrically and mechanically engaged within the card edge connector (70) for communication between the computer and the corresponding peripheral.
Abstract:
An electrical connector assembly includes a first insulative housing (12) which defines a plurality of first passages (14) extending therethrough for receiving corresponding electrical conductive members (22). The first insulative housing (12) also defines a corresponding number of apertures (42) thereof for receiving electrical filtering components (30), such as a TVS chip, and each apertures (42) is parallel to and communicates with one side of the first passage (14). A second insulative housing (16) defines a plurality of second passages (38) corresponding to the first passages (14) of the first insulative housing (12) for receiving the same conductive members (22), and also defines a corresponding number of cavities (40) thereof for receiving conductive bridge members (34). Each conductive bridge member (34) is dimensioned for fixedly abutting against the filtering component (30) and being clipped (48) by the intermediate contact region (28) of conductive member (22) without welding or bonding to make the communication between the electrical filtering component ( 30) and the conductive member (22). At the same time each conductive bridge member (34) provides a means for preventing the transference of torsional forces or axial movement from the conductive member (22) to the electrical filtering component (30).
