Abstract
An electrical connector assembly that detaches and mates in wet or contaminated environments is disclosed. The electrical connector assembly is configured for displacing and draining water and other contaminants from contact pins and surrounding surfaces during the connection process. As the electrical connector assembly is mated, water and other containments are removed from the contact pins and the surfaces surrounding the contact pins. This prevents contact pins from electrically shorting with other contact pins as a result of undesired current flow through the water collected on the surface.
Claims18
An electrical connector assembly comprising:
- a first housing having at least one male elongated pin member;
- a second housing configured to mate with said first housing, said second housing having at least one opening for receiving a corresponding male elongated pin member of said at least one male elongated pin member, wherein:
- said second housing is configured for displacing contaminants to a drainage pathway during a process of connecting said second housing and said first housing;
- said second housing further comprises a top surface and at least one locking tab;
- said at least one male elongated pin member extends beyond said top surface of said second housing when said second housing is coupled to said first housing;
- and
- said at least one opening forms at least one fluid-tight annular space surrounding said corresponding male elongated pin member during said process of connecting said second housing and said first housing.
