A modular jack [200] includes a jack housing [220] with an opening [225] in its front end that is adapted to receive a modular plug [100]. Within the opening there are a number of jack springs [215] for making electrical contact with metallic blades [120] that are installed in the plug. Variations in the actual positi on [211] where the plug blades make contact with the jack springs are reduced by the inclusion of a positioning member within the housing. This is extremely important in situations where the modular plug includes crosstalk compensation, since positional variations affect the amount of crosstalk compensation needed. In one embodiment, the positioning member comprises a cam [228] that engages a flexible latch [130] on the modular plug to create an axial force [Fl] that pushes the plug toward a retaining surface [229] within the housing. In another embodiment, the positioning member comprises a spring [213], other than the jack springs, that engages a rigid surface [135] on the modular plug to create an axial force [F2] that pushes the plug toward the fixed retaining surface.
