Plug connector having end node termination module

An end node termination module for a plug connector comprising:

• a termination module housing including a main body having a pocket, the main body including an access window open to the pocket;
• and
• an end node printed circuit board (PCB) received in the pocket, the end node PCB including an end node control circuit having an end node control component mounted to the end node PCB to control the end node control circuit;
• wherein the end node PCB is configured to be electrically connected to at least one of a power contact of the plug connector and a signal contact of the plug connector by at least one jumper contact of the plug connector through the access window.

An electrical connector system comprising:

• a header connector including a header housing holding header contacts, the header housing including a receptacle, the header contacts including mating ends in the receptacle;
• and
• a plug connector received in the receptacle and mated to the header contacts, the plug connector comprising:
• a plug housing having a mating end and a cable end, the mating end configured to be mated with the header connector, the plug housing including a power contact channel between the mating end and the cable end, the plug housing including a first module channel between the mating end and the cable end, the plug housing including a second module channel between the mating end and the cable end;
• a power contact received in the power contact channel, the power contact being terminated to a power cable, the power contact including a mating end configured to be mated to the corresponding header contact of the header connector;
• a data module received in the first module channel, the data module including a data module housing holding signal contacts terminated to ends of signal wires of a data cable, each signal contact including a mating end configured to be mated to the corresponding header contact of the header connector;
• an end node termination module received in the second module channel, the end node termination module including a termination module housing with a pocket, the end node termination module including an end node printed circuit board (PCB) received in the pocket, the end node PCB including an end node control circuit having an end node control component mounted to the end node PCB to control the end node control circuit;
• jumper contacts held by the plug housing, each jumper contact including a signal contact mating interface electrically connected to the corresponding signal contact and an end node mating interface electrically connected to the end node termination module to electrically connect the signal contacts to the end node control circuit within the plug connector.
