Electrical connector system with alien crosstalk reduction devices

An electrical connector comprising:

• a connector housing having a front end and a rear end, the connector housing including:
• a cavity opened at the front end for receiving a plug;
• and
• a plurality of insulation displacement contacts supported by the connector housing and extending from the connector housing at the rear end, wherein the plurality of insulation displacement contacts includes a first pair, a second pair, a third pair, and a fourth pair;
• and
• a cap configured to be mounted to the connector housing at the rear end, the cap being made from a material suitable for shielding cross-talk, the cap including:
• a first side wall, a second side wall opposite to the first side wall, and a third side wall extending between the first side wall and the second side wall, the first, second, and third side walls configured to partially cover the connector housing when the cap is mounted to the connector housing, the cap including an open side arranged opposite to the third side wall, the open side configured to at least partially expose the connector housing therethrough when the cap is mounted to the connector housing;
• an end wall having a first end and a second end opposite to the first end, the end wall being attached to the first, second, and third side walls to form an end portion of the cap, wherein the first end of the end wall is attached to the first side wall and the second end of the end wall is attached to the second side wall, the end portion having an inner surface and an outer surface, and the end portion defining a cable opening with a predetermined form factor sized and shaped to receive a cable therein, the predetermined form factor having a closed end and an open end;
• wherein the predetermined form factor includes a rounded portion at the closed end and a neck portion at the open end that extends from the rounded portion to form an open end at the open side;
• a first shoulder formed on the first side wall that connects with the end portion at the first end thereof, and a second shoulder formed on the second side wall that connects with the end portion at the second end thereof, the first and second shoulders having a length that extends from the third side wall to the open side, the first shoulder having a first plurality of cross-walls projecting therefrom and the second shoulder having a second plurality of cross-walls projecting therefrom;
• a plurality of barriers positioned on the end wall, wherein the plurality of barriers includes a first barrier extending along a first edge of the neck portion, a second barrier opposite to the first barrier extending along an opposite, second edge of the neck portion, a third barrier extending from the third side wall in a direction towards the first barrier, and a fourth barrier extending from the third side wall in a direction towards the second barrier;
• the first, second, third, and fourth barriers each having a cross-wall extending thereon, the cross-walls of the first and third barriers extending in a first direction that opposes the first plurality of cross-walls of the first shoulder, and the cross-walls of the second and fourth barriers extending in a second direction that opposes the second plurality of cross-walls of the second shoulder;
• and
• a latch positioned on an inner surface of the first and second side walls, the latch being configured to engage a corresponding latch receptacle of the connector housing to mount the cap to the connector housing.
