ABSTRACT:
A waterproof electrical connector for airfield lighting applications has a connector body with a first end and an opposing second end. The first end terminates at a first end cap that has a strain/bend relief feature and a first bore for receiving a cable that extends into the first end. At least one O-Ring extends from the walls of the first bore. The opposing second end terminates at a second end cap and has a second bore extending through the second end cap and into the second end. A sleeve is affixed to an exterior surface of the second end cap. An electrically insulated cable is inserted into the first bore engaging the O-Rings to form a waterproof seal. An electrical contact engages the second end cap and the sleeve folds over the second end cap to engage a surface of this contact forming a waterproof seal.
