Abstract

A modular power distribution system includes power distribution assemblies and flex connectors. The flex connector includes end connector housings and a flexible jacket that encloses conductor wires extending between the connectors. The jacket is formed from superimposed layers of sheet-like jacket material that is flexible. The bottom jacket layer is first laid on a bottom housing section wherein conductors are then placed thereupon with an upper jacket layer then positioned over the bottom jacket layer. The top and bottom jacket layers have aligned free edges along at least one side thereof wherein the free edges are bonded together such as by heat sealing.
