<p>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 position 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 "F1" 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.</p> |
