Abstract: The seal spring of the present invention has a dual functionality. The seal spring provides both a sealing property and spring function in use within an electrical connector system, which is accomplished by its elastomeric qualities. The seal spring is preferably comprised of Silicone, EPDM rubber or materials and compositions that provide similar performance during use, or the like. The seal spring of the present invention is not limited or defined into a spring section or a seal section by its geometry. Shown is an implementation of the seal spring within an outer housing and connector assembly. The seal spring compresses and provides adequate spring force against a tab or tabs within the outer housing. The seal spring also functions as an interface seal and an environmental seal during use. The seal spring is, substantially, in its entirety, of a contiguous and continuous single construction. No part or section of the seal spring is made up of welded, soldered, or brazen part or section.
