Abstract: Aspects of the technology relate to rotational electromechanical systems, in which data and or power are supplied to components while one part of the system is rotating relative to another part of the system. Repeated rotation may create strain on or otherwise cause the cables to intermittently or permanently fail. A helical cable management system is provided that enables full rotation to the extent permitted. One or more cables are wound in a helical shape around the axis of rotation, which distributes the deformation of the cable along the helical length. Rotation in one direction causes the helix diameter to increase, while rotation in the other direction causes the helix diameter to decrease. A structure is used to maintain the distance between helical turns, while permitting the increase and decrease of the helix diameter. This reduces the overall strain on the cables, which can significantly extend their useful lifetime.

Abstract: 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.

Abstract: A method and system are disclosed that allow easier coupling between high-density connectors. In one example implementation, the connectors on a computer board are mounted on flexible tabs extending from the computer board, the tabs having been formed by cutting slots on both sides of each of the tabs. A milled section within each tab makes the tab thinner, allowing it additional flexibility. In another example implementation, a pass-through connector is used as an intermediary between two mating connectors. The pass-through connector has internal pins with greater tolerance than the tolerance between the two mating connectors, allowing it easier alignment of pins for coupling. In yet another example implementation, mating connectors are coupled using a bundle of cables between the mating connectors that allows the coupling of multiple connectors, one at a time, reducing or eliminating the need to simultaneously couple multiple connectors.
