The receptacle cage has walls including a front wall, a rear wall and side walls defining a cavity. A module channel is defined in the cavity configured to receive a pluggable module. The module channel has a module port at the front wall that receives the pluggable module. An airflow channel is defined by at least one of the walls of the receptacle cage located between the module channel and the circuit board. The airflow channel is configured to be in flow communication with the airflow opening in the circuit board for cooling the pluggable module in the module channel. The airflow channel has an airflow port at the front wall.

An electrical coupler has first and second housing halves and first and second contacts retained within the first and second housing halves. Wherein the first housing half is identical to the second housing half and the first contact is identical to the second contact.

An electrical coupler has first and second housing halves and first and second contacts retained within the first and second housing halves. Wherein the first housing half is identical to the second housing half and the first contact is identical to the second contact.

A receptacle cage includes shielding walls forming a module channel configured to receive a pluggable module. The shielding walls include a first end wall, a first side wall extending from the first end wall and a second side wall extending from the first end wall opposite the first side wall. The first end wall, the first side wall and the second side wall form the module channel. The receptacle cage includes a hood extending from the first end wall forming a chamber located outside of the module channel. The receptacle cage includes a cage polarization slot formed in the first end wall at a first distance from the first side wall. The cage polarization slot is open to the chamber. The cage polarization slot is configured to receive a module polarization feature of the pluggable module such that the module polarization feature is located in the chamber and covered by the hood.

Each terminal module comprises a plurality of contacts mounted in a dielectric terminal module housing, the terminal modules having a width W to height H ratio W/H greater than three.

A power distribution system includes a track having a first end, a second end opposite the first end, and a longitudinal axis extending through the first and second ends. The track defines a channel extending along the longitudinal axis. A plurality of power cables is positioned within the channel. The power distribution system further includes an electrical hub having a body coupled to the second end of the track. A plurality of wafers is supported by the body and stacked on top of each other to define a set of terminals. The set of terminals is electrically connected to the plurality of power cables. A power receptacle is supported by the body and electrically connected to the plurality of wafers.

A connector includes a housing, a first sandwich structure, and a support structure. The housing includes two accommodating cavities vertically adjacent to each other, where each accommodating cavity is used for receiving a docking connector. The first sandwich structure is disposed between the two accommodating cavities. The support structure penetrates two side walls of the housing and two side walls of the first sandwich structure to fix the first sandwich structure on the housing.

A connector module provided on an end part of a communication cable used in communication of 100 Mbps or faster includes a first terminal, a connector member for accommodating the first terminal, and a tubular shield member for covering an outer periphery of the connector member, and the shield member is a cast body.

A plug connector module is provided for a modular industrial plug connector, wherein the plug connector module is formed from at least two independent functional units. In order to fit a holding frame with a plug connector module, a first functional unit is first of all combined with at least one second functional unit so as to form a plug connector module, and the plug connector module is then inserted into the holding frame.
