A connector that enables electronic assemblies to be efficiently configured for any of multiple power requirements. The connector may have multiple interfaces such that when the connector is mounted to a printed circuit board (PCB), it may receive power through an interface and distribute it to components on the PCB through another interface. The connector may also have an interface that supports a connection to a conductive interconnect, which may distribute power to a second connector mounted to the same PCB. Power may be distributed to components mounted to the PCB without passing through the mounting interface of the first connector. As a result, the current density in the PCB adjacent the first connector is reduced relative to current density required to supply current to all components through the mounting interface of the first connector. The PCB may have fewer layers than a conventional PCB assembly supporting comparable functionality.

An electrical connector pair 1 includes a receptacle connector 1a and a plug connector 1b. The receptacle connector 1a includes a first partition wall 12a, and the plug connector 1b includes a second partition wall 12b. When the receptacle connector 1a and the plug connector 1b are fitted together, the first partition wall 12a partitions a portion of the boundary between a third holder and a fourth holder where the second partition wall 12b is not formed such that a first contact 10a and a third contact 10b cannot be seen from a second contact and a fourth contact.

The socket body includes a bottom wall, socket side walls, socket guide parts formed at lateral ends of the socket body, and an island part protruding upwards from the bottom wall. Socket guide parts each include a plug guide part receiving cavity, longitudinal outer peripheral wall, and lateral outer peripheral walls. The socket strengthener includes a main body part, lateral outer peripheral wall, and elastic arm parts. Tops of the elastic arm parts bend and extend towards longitudinal outer sides to form hitching part cavities hitched on top faces of the lateral outer peripheral walls.

A modular electrical connector with separately shielded signal conductor pairs. The connector may be assembled from modules, each containing a pair of signal conductors with surrounding partially or fully conductive material. Modules of different sizes may be assembled into wafers, which are then assembled into a connector. Wafers may include lossy material. In some embodiments, shielding members of two mating connectors may each have compliant members along their distal portions, such that, the shielding members engage at points of contact at multiple locations, some of which are adjacent the mating edge of each of the mating shielding members.
