Abstract: A connector assembly comprises a male connector with pin terminals, and a female connector with receptacle terminals matable therewith. The male terminal comprises a separator protrusion adjacent the contact engageable with separating extensions of contact arms of the female terminal. During coupling, the contact arms are biased apart by engagement with the separator protrusion thereby preventing rubbing of the contact surfaces during initial coupling. The latter reduces wear of the contact surfaces and also reduces mating forces.

Abstract: The method and the plug connector are employed in the transmission of data at high frequencies to reduce propagation delay differences in data transmission lines, where a data transmission line is connected to a plug connector having a conductive structure located between a conductor connection contact and an associated plug transfer contact, where during production, the propagation delay difference between the signals on the two conductors is measured and compensated for by removing conductor sections from the conductive structure for which the shorter propagation delay is measured in order to extend the length of the signal path.

Interposed between adjacent terminal modules are shielding members that serve to limit crosstalk between adjacent rows of contacts. The shielding members are attached to over-moulded insulative webs of the terminal module and are resiliently biased thereagainst so that they ensure good contact of an integral grounding pin with one of the right angle contacts of the terminal module and also to ensure a flush fit of the grounding shield against the terminal module.
