ABSTRACT:
Each of female type contact pieces is surrounded by a flexible elastic member. While a female type connector half is connected to a male type connector half, a plurality of water inflow preventive protuberance slightly projected from the foremost end of the male type connector half are forcibly squeezed in the flexible elastic member, causing the respective contact pieces to be watertightly separated from each other. The repulsive force accumulatively arising in the flexible elastic member due to compression of the latter acts to thrust contact parts in the female type contact portions from the outside in the transverse direction. Thus, an intensity of contact pressure between the female type contact pieces and the male type contact pieces is increased, whereby both the female type contact pieces and the male type contact pieces are reliably connected to each other no matter how they are contaminated with oil. While the female type connector half and the male type connector half are disconnected from each other, they can easily be washed using water. Subsequently, when they are connected to each other, there does not arise a malfunction of short-circuit due to the water remaining after completion of the washing operation.
