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.
