Abstract:
PROBLEM TO BE SOLVED: To reduce other signal noise to be mixed into a signal line for connecting modules or noise caused by other signals infiltrated into a power supply in a mother board for backplane bus. SOLUTION: Part of a power supply layer constitutes part of a microstrip line structure (where a power supply layer is arranged adjacent to one side of a signal layer, and air is arranged on the other side) or a stripline structure (where power supply layers are arranged adjacent to both sides of a signal layer), and is not relevant to signal transmission between mother board modules for backplane bus. An EGP pattern, consisting of two interconnections having different impedances, is arranged periodically in three or more rows. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an interconnection assembly by which facilitates a transmission speed of 10Gbps or more. SOLUTION: The interconnection assembly 100 includes a rear face 110 and a line card 130. A plurality of cables 120 provided at the rear face 110 have fixed ends 121 connected to the rear face 110, free ends 123 extending in a direction away from a surface and several parallel flexible conductors 125 extending between the both ends, respectively. A cable 140 of the line card 130 also includes a fixed end 141, a free end 143 and a flexible conductor 145 extending between the both ends. A connector 150 is also provided at the rear face 110. In the connector 150, the free ends of the cables 120 are electrically combined with the free end of the cable 140, and the connector detachably combines the cables 120 with the cable 140.

Abstract:
In accordance with one embodiment, an electrical connecter system can include an electrical signal connector and an electrical power connector. The electrical signal connector and the electrical power connector can be mounted on opposed surfaces of a printed circuit board. The electrical power connector can be constructed as a hermaphroditic power connector that includes at least one header power contact supported by a connector housing, and at least one receptacle power contact supported by the connector housing.
Abstract:
A system for communicating between multiple electrical components includes a first printed circuit board (PCB) having first and second opposed layers and a plurality of plated through-holes extending between the first and second opposed layers. The system also includes a plurality of mating contacts, wherein each of the plurality of mating contacts is retained within one of the plurality of plated through-holes. Each of the plurality of mating contacts may include a first end portion that outwardly extends from the first layer, and a second end portion that outwardly extends from the second layer. The system may also include a first connector assembly having a plurality of interconnecting contacts retained therein. The plurality of interconnecting contacts mate with the first end portions of the plurality of mating contacts when the first connector assembly connects to the first PCB.
