Modular jack assembly

An electrical jack assembly adapted to electrically mate with an electrical plug which has a plurality of electrical plug contacts mounted therein, said jack assembly including

• a receptacle housing having a forward plug-receiving end and a rearward end, said housing further having a first socket portion with a plug-receiving opening extending into the forward end arranged to removably and telescopically receive said plug, said receptacle housing further having a second socket portion adjacent the first socket portion with a jack contact connector opening extending into the rearward end,
• a discrete jack contact connector adapted to be removably and telescopically received through said jack connector opening into said second socket portion, said connector having a connector housing with a plurality of wire receiving receptacles formed therein and plurality of jack contacts having spring portions adapted to electrically engage said plug contacts when both the jack contact connector and plug are received in said receptacle housing, said jack contacts each having a wire mating portion disposed in a wire receiving receptacle and adapted to electrically contact an insulated wire conductor received in said wire receptacle,
• the improvement in said jack contact connector comprising:
• said wire receptacles arranged in two rows so that every other wire receptacle is in a different row, thereby defining a staggered configuration;
• said wire mating portion having an insulation displacement slot adapted to slice through the insulation of the wire to touch the conductor;
• a hinged cover integrally formed with said connector housing and including strain relief means extending toward the electrically connected wires, said strain relief means including first means for securing wires within the first row of wire receptacles and second means for securing wires within said second row of wire receptacles, said cover being moveable between an initial open position and a closed position wherein said strain relief means traps said wires and serves to prevent accidental withdrawal of the wires from the insulation displacement slots of their respective jack contacts.
