A wire terminal block for communication connectors. The block includes a mandrel, and a frame arranged for mounting on a printed wire board and for supporting the mandrel on the board where a number of terminal wires emerge to contact a mating connector. A number of slots are formed along the mandrel, and an inner contour at a base of each slot is configured to form a desired bend radius in the terminal wires when the wires are seated in corresponding ones of the slots and are wrapped about the mandrel within the slots. In one embodiment, the inner contour of the mandrel is configured to form a first bend radius in the terminal wires at a side of the wire board from which the wires emerge, and to form a second bend radius in the terminal wires with which the wires angle back over an opposite side of the wire board to contact the mating connector.
