Electrical connectors and the combination of a series of these connectors and a wire-connecting apparatus

First and second housing parts (11 and 12) are fixed together in spaced relation with a disc-like contact member (14) having wire gripping slots (54) rotatably mounted between them. The slots have mouths (53) aligned with wire receiving passageways (23, 33) in the first and second housing parts. Tabs (51) on the contact member (14) are locked in recesses (44) in a third housing part (13) rotatably mounted on the first housing part (11) by cooperating ribs (42) and groove (16) and defining a cavity enclosing the second housing part (12) and contact member in a reservoir of sealant. The connector is adapted for operation by a hand tool which rotates the third housing part (13) relative to the first housing part (11) to drive wires inserted in the passageways (23, 33) into the slots.
