A plug comprises a plug housing having a body and a plurality of beams extending therefrom and forming gaps therebetween. A member bridges the gaps between the beams at their distal ends. Ground contacts comprising a body, an elongated contact portion, and armatures are inserted into the plug housing. A recess formed in the distal end of the elongated contact portion engages the member. The ground contacts have projections extending therefrom that are disposed in channels formed through the body and along the beams. Signal contacts having a portion with a first form factor and a portion with a second form factor are also inserted into the plug housing. The portion with a first form factor extends through a conduit in the plug housing body and along a trough formed in the beams. The distal ends of the signal contacts have recesses formed in their distal ends with projections from the beams situated therein. The portion of the signal contact with a second form factor abuts the housing body.
