A power supply device for supplying power to a communication device includes a power source, a first fuse, a second fuse, a voltage converter, a photo coupler, and a central processing unit (CPU). The voltage converter is configured for receiving first power signals from the power source via the first fuse and the second fuse, and converting the first power signals to second power signals. The photo coupler connected in parallel to the third resistor, configured for outputting a first electrical signal upon the condition that the first fuse and the second fuse are operational, and outputting a second electrical signal upon the condition that at least one of the first fuse and the second fuse is blown. The CPU is connected to the photo coupler, configured for generating an alarm message upon receiving the second electrical signal from the photo coupler.

Power supply device

A carrier (,) comprises a guiding tape (,) from which a plurality of linking strips (,) extend and engage with a plurality of contacts (,) each of which comprises a mating portion (,) having a first half (,) and a second half (,) connected to each other via an engagement plate (,). A plurality of compliant pins (,) extends from the first half (,) and each compliant pin (,) terminates as a free end (,). A plurality of linking strips (,) engages with each first half (,). A guiding tape (,) engages with the linking strips (,) so that each linking strip (,) is connected between the first half (,) and the guiding tape (,). A coining step to round the edge of compliant portions (,) is to be carried out. The attachment of the guiding tape (,) to the linking strips (,) rather than to the free ends (,) of the compliant pins (,) facilitates such coining step.

Carrier for socket type contacts having compliant pins

A connector device having a grounding plate which is formed with a cut-out region so that an array of pin contacts may extend through without needing to bend the grounding plate to such a degree as to occupy a significant space on or above a mother board.

Grounding plate for a connector device

The present invention provides a contact which facilitates proper insertion into a housing of an electrical connector without deflection of the contact after configuration. The contact of the electrical connector comprises a main plate having a central flat portion and two bent sides projecting therefrom and facing each other. A mating terminal includes two clamping branches respectively extending from the bent sides of the main plate along a longitudinal axis of the main plate. A compliant pin extends from one end of the central flat portion of the main plate opposite the extending direction of the mating terminal and is substantially right angled at an intermediate portion thereof. A tail terminates from the compliant pin and defines a hole therein for engagement with a hole of a circuit board. A curved shoulder is formed near the tail for facilitating insertion of the tail into the hole of the printed circuit board. The curved shoulder fits within the housing if the connector when the contact is assembled in the housing.

A contact strip includes a plurality of terminals (10) joined together by a material band (50). Each terminal (10) includes a connection portion (11) having a first contact portion (13) extending from one end thereof for reception in a receptacle connector (80) and a second contact portion (14) extending from another end thereof for engagement with a PCB. A pair of opposite cutting cutouts (30) is defined in each end of the connection portion (11) adjacent to the adjoining material band (50) for facilitating the separation of the terminals (10) from the contact strip by means of a cutter (90) cutting along a straight line 'C'.

Density contact strip and process of separation thereof

Header connector portion (10) of a future bus connector includes an insulative housing (12) having a bottom wall (14) defining a plurality of passageways (20) therethrough for receiving a corresponding plurality of compliant pins (22) therein and two side walls (16, 18) projecting upward from two opposite sides of the bottom wall (14), respectively. Each pin (22) includes a contact portion (24) for engaging with a complementary contact of a receptacle connector portion of the future bus, a retaining portion (26) having an embossed retention mechanism (29) formed thereon for interferentially engaging with inner walls (17) of the passageways (20) of the housing (12), and a tail portion (30) having an eye (32) of the needle engagement feature for reception in a corresponding hole defined in a PCB. The retention mechanism (29) includes two projections (27, 28), wherein one projection (27) is ramp-shaped and the other projection is either a partial sphere or a partial cylinder (28). The pins (22) are inserted into the passageways (20) so that the projections (27, 28) exert a force perpendicular to a longitudinal direction of the housing (12) on an inner wall (17) of each corresponding passageway (20).

Header connector of a future bus and related compliant pins

A board adapter for electrically connecting an electrical card connector to a mother board, comprises 68 signal holes, 100 conductive pads, a plurality of signal traces, a first grounding means, a transforming unit and a second grounding contact. The first grounding contact surrounds the signal holes and is electrically connected with a corresponding grounding contact of the electrical connector, for providing the signal holes and the electrical connector with grounding protection. The second grounding contact is alternately juxtaposed with every two of the signal traces for providing grounding protection. The conductive pads are electrically connected with either the signal traces or the grounding contacts. The transforming unit includes two power traces to separately bear two different strength voltage induced currents. When either of the traces bears a corresponding voltage induced current, the other trace can be transformed into a grounding trace to protect the bearing trace.
