Differential transmission cable and joint with specific distances
First Claim
1. A differential transmission cable comprising:
- a cable having (1) at least one pair of differential transmission lines, (2) at least one transmission transformer, and (3) a first connector and a second connector respectively positioned at the ends of said cable, said at least one transmission transformer being positioned along the length of said cable between a tip end of said first connector and a tip end of said second connector, wherein the distance between a center of said at least one transmission transformer and the tip end of said first connector is 0.1 m or less, and wherein one of (1) the distance between a center of said at least one transmission transformer and the tip end of said second connector is 0.5 to 4 m and (2) the distance between a center of said at least one transmission transformer and a center of another transmission transformer is 0.5 to 4 m.

Abstract
The differential transmission cable comprises a cable having at least one pair of differential transmission lines, one or more transmission transformers, and connectors at both ends, the transmission transformer having an integrally sintered laminate structure and a coupling coefficient of 0.65 to 0.98 at 100 MHz, the distance between a center of the transmission transformer and a tip end of the closest connector being within 0.1 m, and the distance between a center of the transmission transformer and a tip end of the farthest connector or between a center of the transmission transformer and a center of the other transmission transformer being 0.5 to 4 m. The transmission transformer is mounted onto a substrate, which is inserted into the connector or a housing of the connector having lands or a positioning holder. After wiring, the connector including the substrate is integrally resin-molded.

14. A differential transmission cable comprising:
-
a cable having (1) at least one pair of differential transmission lines, (2) at least one transmission transformer, and (3) a first connector and a second connector respectively positioned at the ends of said cable, said at least one transmission transformer being positioned along the length of said cable between a tip end of said first connector and a tip end of said second connector, wherein the distance between a center of said at least one transmission transformer and the tip end of said first connector is λ
/20 or less, and wherein one of (1) the distance between a center of said at least one transmission transformer and the tip end of said second connector is λ
/4 to 2λ
and no other connector is provided between said second connector and said at least one transmission transformer, and (2) the distance between a center of said at least one transmission transformer and a center of another transmission transformer is λ
/4 to 2λ
, andwherein λ
represents the wavelength of a noise that radiates from said differential transmission cable, which is to be attenuated.- View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
