A system includes a cage and a first coil. The cage includes a first end and a second end opposite the first end. The first end is arranged to receive an electrical connector. The second end is arranged to receive a pluggable module such that the electrical connector forms an electrical connection with the pluggable module. The first coil is positioned on or in the cage such that the first coil is arranged to deliver electric power to the pluggable module by inducing an electric current in a second coil positioned in or on the pluggable module when the pluggable module is connected to the electrical connector in the cage.

A layout method applied to a connector is provided. The connector is electrically connected between a flexible printed circuit (FPC) and a printed circuit board (PCB). The FPC includes M pairs of differential lines and X shield lines. The PCB includes M pairs of differential lines and Z shield lines. The layout method includes following steps. Firstly, M pairs of conductive lines are disposed on the connector. The M conductive lines are correspondingly electrically connected to the M differential lines of the FPC and the M differential lines of the PCB. Then; Y conductive lines are disposed on the connector, wherein Y is smaller than X. Furthermore, at least one of the Y conductive lines is electrically connected to at least one of the X shield lines and at least one of the Z shield lines.

A receptacle connector having a plurality of airflow holes positioned to avoid heat buildup inside a receptacle shell, preventing deformation to the housing of a short, high density connector during solder reflow. The airflow holes may be in a bent portion joining a top face and rear face of the shell. The receptacle connector may be mounted to a substrate, such as a printed circuit board, leaving a gap between the connector and the substrate, forming an airflow passage between the substrate and the receptacle connector, enabling heated air to reach mounting portions of terminals of the connector during soldering, but reducing heat buildup within the shell. The passage, alone or in combination with a cutout in a face of the shell, may expose terminal contacts of the receptacle connector to provide for easy inspection and rework of the solder joints between the terminal contacts and the substrate.

An electrical connector includes: a plastic housing provided with a receiving cavity extending in a front-rear direction therein; a metal stopping member provided in the housing, including at least one fixing portion embedded in the housing and a body exposed to the cavity, the body is provided with a through hole; a terminal base including a base portion and a tongue extending forwardly from the base portion, the terminal base is mounted in the cavity, the body of the metal stopping member blocks in front of the base portion, the tongue passes through the through hole of the metal stopping member and extends forwardly; and a plurality of conductive terminals fixed to the terminal base, each terminal includes a contact portion which is exposed to the tongue and a soldering portion which rearwardly extends out of the terminal base.
