  "description_excerpt": "This invention generally relates to the art of electrical connectors and, particularly, to a modular system for arranging a plurality of electrical connector assemblies in a stacked array.\n\nElectrical connectors are used in a wide variety of applications ranging from simple connecting interfaces between hard conductor wiring to more sophisticated applications involving such components as printed circuit boards, flat flexible cables and optical fibers. Basically, electrical connectors include some form of contacts, terminals or other conductors which interconnect one electrical device to another electrical device. As used herein, the terms “electrical” or “electrical connectors” or the like are intended to include optical devices.\n\nIn some environments, it is desirable to stack electrical connector assemblies with one connector assembly on top of another connector assembly. One such environment is in the data processing system of a computer wherein different connectors perform different information and regulating tasks. There are other environments wherein stackable electrical connectors would be desirable, but most systems for stacking connector assemblies are complicated and not user friendly.\n\nFor instance, a modular system for stacking electrical connector assemblies would be desirable and very useful in the automotive or vehicular industry for interconnecting various consumer electronic products. There currently are numerous products which are used within vehicles, such as GPS systems, cellular telephones, MP3 players, CD players, wireless devices and the like.",
