A wire lead guide arrangement provided on a terminal housing of a communication connector. The terminal housing includes a base wall, and two rows of terminal posts disposed at opposite sides of the base wall. The terminal posts are configured to receive outside wire leads for establishing connections between the leads and connector terminals associated with the terminal posts. A wire guide structure in the form of a wall or bar extends between the two rows of terminal posts. The guide structure is configured to separate and prevent interaction between a first set of leads terminating at one row of the terminal posts, and a second set of leads terminating at the other row of terminal posts. The arrangement avoids variations in lead placement that might tend to degrade rated connector performance, particularly with respect to near end crosstalk (NEXT).

A communication plug that generates crosstalk, at a predetermined level, that complements the compensating crosstalk in a legacy jack or connector. The communication plug includes an electrical connector assembly comprising a plurality of conductive blades. Each conductive blade is adapted to make electrical contact with an insulated conducting wire and with a jack spring contact. At least two of the conductive blades are configured so as to cross over each other without making electrical contact. Complementary crosstalk is generated between the conductive blades in the region where the blades engage the jack spring wires or terminals thus minimizing the propagation delay between the crosstalk signals generated in the plug and the crosstalk signals generated in the jack or connector.

A modular plug (23) for terminating cordage includes a housing (41) having a free end (46) and a cordage-input end. An end portion of a length of cordage (21) to be terminated by the plug is inserted into the cordage-input end of the housing to cause exposed individually insulated conductors extending beyond a jacketed portion of the cordage to be received in a conductor-holding portion of the housing. Blade-like terminals (42--42) inserted into slots opening to an exterior surface of the housing engage electrically the conductors. An anchoring member (61) is caused to be moved to an operative position whereat a primary jacket anchoring surface (74) of the anchoring member becomes disposed in compressive engagement with a jacket of the cordage. The geometry of the anchoring member is such that the primary anchoring surface in an unoperated position is angled to a longitudinal axis of the end portion of the length of cordage. Also, the jacket anchoring surface has suitable length so that when in an operated position in which the jacket anchoring surface is substantially parallel to the longitudinal axis of the end portion of the length of cordage, relative motion between the housing and portions of the cordage outside the housing do not induce undue stress concentrations in the cordage. The anchoring member secures the end portion of the cordage against unintended movement with respect to the housing and transfers forces applied to the cordage to the housing. Strain-relief facilities also are provided for the insulated conductors and are such that a conductor restraining bar (75) under the application of forces is moved substantially linearly into engagement with the conductors.

The epoxy resin stabilizing systems in combination with cadmium containing stabilizers employed in PVC compounds are replaceable without affecting other properties of the polymer by utilizing a specific additive mixture. In particular, a complex ester of oleic acid and a diglycerol ester of oleic acid are employed in conjunction with a calcium-zinc composition. The resulting system yields excellent processing and long-term stability without significantly affecting other properties such as color stability and flame retardancy.
