A contact includes a cantilever beam and a protection tab. The cantilever beam extends from a beam connected end to a beam free end along an insertion direction. The protection tab extends from a tab connected end to a tab free end in a direction opposite to the insertion direction. The tab free end is positioned adjacent to the beam free end.

In a connector assembly in which a first connector that includes a first insulator, first terminals, and a first shell and is mounted on a first board and a second connector that includes a second insulator, second terminals, and a second shell and is mounted on a second board are connected with each other, a first ground pattern that has a frame-like shape and is formed on the first board is soldered to the first shell with first solder, and a second ground pattern that has a frame-like shape and is formed on the second board is soldered to the second shell with second solder. An inner space in which the first terminals and the second terminals are positioned is completely shielded from the outside without any gap.

A modular connector includes a housing, a circuit board located in the housing, a connector assembly connected to the circuit board, and a coil module mounted to the circuit board. The connector assembly includes a number of conductive terminals. The coil module includes a first coil module and a second coil module. The first coil module includes a number of first coils and a number of first coil groups. The second coil module includes a second coil. The second coil is divided into a number of second coil groups along its circumference. The first coil groups and corresponding second coil groups are coupled, thereby improving the electromagnetic shielding effect of the modular connector.

A shielding spring shell has a contact tab with a pair of spring sections adjoining a fillet. One of the spring sections is an at least radially resilient radial spring and another of the spring sections is an at least axially resilient axial spring.

An EMI filtering, coaxial power connector may be formed as an inline component or a port of a device. The connector may have dimensions to accept F-type coaxial connectors. The connector includes a conductive outer shell with a first opening and a second opening. A dielectric member is disposed within the shell. A conductive pin is supported by the dielectric member. A feed-through capacitor has a central opening and a first lead formed within the central opening. The pin is electrically connected to the first lead. A second lead of the capacitor is formed at an outer perimeter of the capacitor and is electrically connected to the shell. A metal plate is mounted within the shell. The plate is disk-shaped with a central hole. An outer perimeter of the plate is in electrical contact with the shell. The pin passes through the central hole without making electrical contact with the plate, and the plate resides between the second opening of the shell and the capacitor.

A stacked I/O connector for use with a high speed, high density transceiver that generates a large amount of heat. The connector may be formed with a web-like housing into which leadframe assemblies are inserted. The web-like housing may have openings in the front, back, top and/or sides, enabling airflow through the connector with little resistance. Sidewall openings may open into a channel between the housing and a wall of cage, enabling air flowing to cool transceivers inserted into the cage to pass through the connector assembly with low resistance and high cooling efficiency. A cage for the connector may have openings selectively positioned such that air flowing through the cage to cool transceivers mated to the I/O connector may pass through the connector with low resistance, enhancing cooling efficiency. Such a connector may be used with OSFP transceivers to meet signal integrity and thermal requirements at 112GBps and beyond.
