US 8,708,755 B2 · Connection blade, intermediate connection electrical connector having connection blade, and connection blade assembly

Abstract

A connection blade, an intermediate connection electrical connector and a connection blade assembly including the connection blade are provided. The connection blade includes an insulation board. The insulation board includes differential pair circuits thereon. The differential pair circuits include a straight pair and a cross pair. Both of the straight pair and the cross pair includes a parallel section where wire paths of the pair extend in parallel. In a region other than the parallel section, the cross pair includes a crossing section where wire paths thereof intersect with each other. In a region other than the parallel section, the straight pair includes a quasi-crossing section where wire paths thereof approach each other in non-contact manner so that the wire paths thereof have the same length and the same shape with that of the cross pair, thereby reducing difference of impedance and manufacturing cost.

Dependent claims

A connection blade for connecting at least two circuit connection portions, comprising:

an insulation board;
a straight pair formed on the insulation board and including a first wire path and a second wire path, said straight pair further including a quasi-crossing section where the first wire path approaches the second wire path;
and
a cross pair formed on the insulation board and including a third wire path and a fourth wire path, said cross pair further including a crossing section where the third wire path crosses over the fourth wire path in a non-contact manner, said crossing section having a shape the same as that of the quasi-crossing section viewed in a direction perpendicular to the insulation board.
