Abstract: An electrical connector includes an insulative housing with a rear base and a mating tongue extending forwardly from the base. Two rows of contacts are retained in the housing. A metallic shielding plate is embedded within the housing and between the two rows of contacts. Each row of contacts defines positions from one to twelve in the transverse direction wherein positions 2&3 and 10&11 are designated for high frequency signal transmission. In the shielding plate the space between corresponding positions 4 and 6, and that between corresponding positions 7 and 9, are of a complete or enlarged hole being essentially fully empty along the front-to-back direction for achieving the high frequency transmission without undesired crosstalk among the corresponding contacts.

Abstract: A card edge connector includes an insulative housing extending along a lengthwise direction, two rows of (contact) passageways formed in two opposite side walls with a central slot therebetween. Two rows of contacts are disposed within the corresponding passageways, respectively. The contacts include signal contacts and grounding contacts. Each side wall further forms an elongated channel by two sides of central wall under the central slot. A covering block is upwardly assembled into the corresponding channel after the corresponding contacts have been assembled into the corresponding passageways. Each block includes a deflectable latch engaged with the central wall. The covering block occupies at least one half of each passageway in the transverse direction perpendicular to the lengthwise direction. The covering block is optimally made of conductive plastic and forms a plurality of abutment ribs to respectively abut against the corresponding grounding contacts, respectively.

Abstract: A queue flushing method includes scanning, by a queue flushing processor, a flushing status of a valid queue from a queue information table to determine a target queue whose flushing status is “to be flushed” in the queue information table, where the queue information table records the flushing status of the valid queue; modifying, by the queue flushing processor, the flushing status of the target queue to “start flushing”; and flushing, by the queue flushing processor, the target queue, where the flushing status of the target queue is modified to “flushing complete” after the target queue is flushed.
