Reduce Space Cable Positional and Rotational Keying

To provide orthogonal and rotational alignment of a connector system mounted on a flexible cable structure while minimizing the space required to perform said function. Normally orthogonal alignment is provided by one alignment pin and then a second pin is added for rotational alignment (see figure below). This disclosure describes a method planned for a high performance cabling solution using a single alignment feature mid-span within a connector to reduce connector length by elimination of one alignment feature region.

Origin key Rotational key (may be slotted)

     As you can see in the above figure there is two regions of the connector set aside for alignment. For dense packaging, this is an issue as the alignment space can be a significant portion of the overall connector footprint. Looking at the figure below there are multiple cable interconnects required along one drawer face. Reduction of overall connector length by consolidation of alignment features is critical to packaging complete system solution.

probably covering a range <2.5, the use of two end alignment segment drives an unnecessary increase in connector length. This could be replaced by two alignment pins in one vertical segment. This is a simple manufacturing change but requires two...
