Modular power distribution system

A modular power distribution system, comprising:

• a client device comprising a client electrical coupler, a peripheral, and electrical connections between the client electrical coupler and the peripheral;
• and
• a host device comprising a host electrical coupler, a cable electrical coupler, and a host bus configured to define electrical connections between the host electrical coupler and the cable electrical coupler, wherein the client electrical coupler and the host electrical coupler are configured to couple with one another when the client device is inserted into the host device to provide a first electrical interface defining a plurality of predetermined electrical connections between the client device and the host device, wherein the cable electrical coupler is configured to couple with a cable to provide a second electrical interface defining a plurality of predetermined electrical connections between the host device and electrical conductors of the cable, and wherein
• (i) the electrical connections between the host electrical coupler and the cable electrical coupler and
• (ii) the electrical connections between the peripheral and the client electrical coupler, are independently configurable to facilitate receipt of a plurality of different client device types supporting varying functionality and to form an electrical circuit suitable for delivering power from the cable to the peripheral, via the predetermined electrical connections defined at the first and second electrical interfaces connecting the cable, the host device, and the client device,
• wherein the host bus comprises two or more bus connectors, each comprising:
• one or more bus terminals configured to couple with one or more electrical conductors of the cable;
• and a rigid bus member connecting the host electrical coupler with the one or more bus terminals, the rigid bus member shaped to follow a path configured not to contact the rigid bus members of other bus connectors,
• wherein the one or more bus terminals include a rigid support member extending between and supported by a first wall and a second wall of a housing of the host device, and wherein the host electrical coupler is rigid and extends between and is supported by the first wall and the second wall.
