Abstract
In a data processing system, a flexible cable includes a pattern of transmission lines formed thereon, the lines having a predetermined width. On the transmission lines are formed a first set of lands each for connecting a connection pin of an RJ45 connector and a second set of lands each for connecting a connection pin of a transmission line connector—each land being wider than a transmission line. A transition region is provided in each transmission line in the vicinity of the land, the width of the transition region increasing gradually from the line width to the land width as the transmission line approaches the pin.
Claims7
A signal transmission connector including a substrate having formed thereon:
- a plurality of signal transmission lines, each signal transmission line having a predetermined width;
- a plurality of terminal areas connected to said signal transmission lines, each terminal area having a specific width different from said predetermined width, said terminal areas acting to input/output a signal onto said signal transmission lines;
- a plurality of transition regions, each transition region being formed between a signal transmission line and a terminal area so that said predetermined width of said signal transmission line is changed gradually to said specific width of said terminal area.
A signal transmission line formed at a predetermined width so as to transmit a signal, said signal transmission line being connected to a terminal area formed at a specific width differently from said predetermined width so as to input/output a signal to be transmitted by said signal transmission line,
- wherein an transition region is formed around said terminal area so that said predetermined width of said signal transmission line is changed gradually to said specific width of said terminal area there as said line goes towards said terminal area.
A signal transmission cable for connecting a network controller in a data processing system to a main circuit board of said data processing system and for connecting said network controller to an external port of said data processing system, said signal transmission cable comprising:
- a first connector for connecting said cable to said network controller;
- a second connector for connecting said cable to said external port;
- a third connector for connecting said cable to said main circuit board;
- a plurality of signal transmission lines extending from said first connector to said second and third connectors, each signal transmission line having a predetermined width;
- and
- a plurality of terminal areas connected to said signal transmission lines at said third connector, each terminal area having a specific width different from said predetermined width, said terminal areas acting to input/output a signal onto said signal transmission lines;
- a plurality of transition regions, each transition region being formed between a signal transmission line and a terminal area so that said predetermined width of said signal transmission line is changed gradually to said specific width of said terminal area.
A data processing system comprising:
- a main circuit board;
- a network controller electrically connected to said main circuit board;
- an external port, connected to said network controller by means of a network data transmission cable, for transmitting and receiving network data from and to said data processing system;
- and
- said network data transmission cable comprising:
- a first connector connecting said cable to said network controller;
- a second connector connecting said cable to said external port;
- a third connector connecting said cable to said main circuit board;
- a plurality of signal transmission lines extending from said first connector to said second and third connectors, each signal transmission line having a predetermined width;
- and
- a plurality of terminal areas connected to said signal transmission lines at said third connector, each terminal area having a specific width different from said predetermined width, said terminal areas acting to input/output a signal onto said signal transmission lines;
- a plurality of transition regions, each transition region being formed between a signal transmission line and a terminal area so that said predetermined width of said signal transmission line is changed gradually to said specific width of said terminal area.
