Abstract
Abstract An inner housing ( 12 ) is formed with terminal accommodation chambers ( 13 ) for accommodating therein terminals ( 14 ) at ends of wires ( 20 ). An outer housing ( 17 ) is formed with wire insertion holes ( 49 ) at a bottom wall portion ( 47 ) thereof in opposition to the terminal accommodation chambers, the bottom wall portion having rubber plug reception recesses ( 48 ) at locations on an inside thereof in opposition to the wire insertion holes. A spacer ( 28 ) has a hollow trunk portion ( 40 ) fitted on the inner housing and adapted to be fitted in the outer housing together with the inner housing, and a bottom wall portion ( 43 ) thereof formed with wire leading cavities ( 44 ). A waterproof rubber plug ( 5 ) for sealing the terminal accommodation chambers comprises a plate portion 52, first rubber plug portions ( 51 ) formed on one side of the plate portion and fitted tight in the rubber plug reception recesses, second plug portions ( 51 ) formed on the other side of the plate portion and fitted tight in the wire leading cavities, and wire leading holes ( 53 ) each provided through a first plug portion, the plate portion and a second plug portion.
