Abstract: An electrical connector (1) includes an insulative housing (3) mounted onto a mother board, and a mulitiplicity of contact modules (7) received in the housing. The housing defines first and second openings (245, 246) in a front portion thereof. Each contact module includes first, second, third and fourth contacts (80, 82, 86, 88) and a ground contact (84). The first and second contacts are inserted into the first opening to form a first signal contact group, thereby providing a first mating interface for a daugher board. The third and fourth contacts are inserted into the second opening to form a second signal contact group, thereby providing a second mating interface for another daughter board. The ground contacts are disposed betweent the first and second signal contact groups. The connector can thereby electrically connect the daughter boards with the mother board simultaneously.

Abstract: An electrical connector assembly (10) includes at least one connector (12) and a shell (14) surrounding the connector. A number of locking tabs (24) extend vertically beyond a joint face (23) of the connector. Each locking tab defines an aperture (242) and a block (243) at a free end thereof. The aperture separates the free end of the locking tab into two spaced portions. The block protrudes outwardly from an outside of one of the two spaced portions. An opening (232) under the block is defined in the joint face for facilitating the molding of the block. The shell defines a number of securing holes (411) engagingly receiving the corresponding locking tabs of the connector. The block can press an outside of the shell to retain the locking tab in the hole. Reliable connection between the connector and the shell is secured.

Abstract: A physical interface card for connection to a data bus associated with a data network node is provided. The physical interface card is adapted to perform without supervision from other data bus connected devices: byte ordering, byte alignment and byte scattering/gathering in conveying data between a data bus connected central memory block and at least one data channel associated with the physical interface card. The functionality is provided via a special function direct memory address device operating in accordance with byte ordering specifications for: data stored in the shared memory block and data conveyed via the at least one data channel. The byte alignment is enabled by direct byte addressing techniques as well as the use of an orphan counter to keep track of processed bytes. An implementation of the orphan counter as a state machine reduces processing overheads.
