Abstract

Systems and methods are provided for water resistant connectors. A male connector includes a rib or a draft angle that creates a seal when engaged with a female connector. A male connector includes an overmold that includes or is made of a thermoplastic elastomer. Male or female connectors include molds that include or are made of a thermoplastic polymer, such as polypropylene. A female connector includes spring contacts that fit within individual pockets of the female connector.
