Detachable sealed multicontact electrical connector

Multicontact detachable sealed electrical connector having two connector halves receiving male and female terminals therein is used to establish a sealed interconnection between conductors in one or more circuits. Conductors in separate circuits are separately sealed, and sealing integrity can be maintained even though less than all of the circuits are interconnected. Terminals are received within cavities in the housing and one housing has a plurality of tubular protuberances defining a cavity extension. Inner seals are positioned around these protuberances and are deflected when partially received within the cavity in the other housing to maintain separate sealing integrity at the interface between the two connectors.
