Sealed electrical connector with secondary locking member

A connector comprising a housing with one or more terminals mounted in corresponding cavities of the housing, and a secondary locking member mountable to the housing and adapted to securely lock the terminals in their corresponding cavities when the secondary locking member engages the housing in a fully locked position, the terminals being insertable into the cavities when the secondary locking member is removed from the housing or in a preassembly position engaging the housing, the connector further comprising a sealing member for sealing between the connector and a mating connector to prevent ingress of fluid into the terminal receiving cavities at a mating section of the housing, wherein the seal member is securely attached and mounted on the secondary locking member, the connector further comprising a coupling assist member for reducing the forces required by an operator to couple the connector with the mating connector, the coupling assist member comprising a camming surface engaging complementary camming portions of the secondary locking member during movement of the coupling assist member from the preassembly position, where the connectors can be initially coupled, to a fully coupled position where the connectors are fully mated together, such that the seal member is partially compressed.
