Abstract

A connector ( 10 ) is provided with a waiting side housing ( 11 ) including a forwardly open receptacle ( 13 ) and is mounted in a mounting hole (H) of a panel (P). A fit-in side housing ( 30 ) includes a terminal accommodating portion ( 31 ) that can fit into the receptacle ( 13 ). Drainage ports ( 21 ) are formed in a lower wall ( 16 ) of the receptacle ( 13 ), and water guides ( 22 ) project into opening areas of the drainage ports ( 21 ) only from parts of opening edges of the drainage ports ( 21 ). Upper surfaces of the water guides ( 22 ) define water guiding surfaces ( 23 ) connected to an upper surface ( 16 S) of the lower wall ( 16 ).

First claim

What is claimed is:

1. A connector ( 10 , 40 ), comprising:
a waiting side housing ( 11 , 41 ) including a forwardly open receptacle ( 13 , 43 ) mounted in a mounting hole (H) of a panel (P);
a fit-in side housing ( 30 ) including a terminal accommodating portion ( 31 ) fittable into the receptacle ( 13 , 43 );
a drainage port ( 21 , 45 ) formed in a lower wall ( 16 ) of the receptacle ( 13 , 43 ); and
a water guide ( 22 ) projecting into an opening area of the drainage port ( 21 , 45 ) only from a part of an opening edge ( 21 F) of the drainage port ( 21 , 45 ), an upper surface of the water guide ( 22 ) defining a water guiding surface ( 23 ) connected to an upper surface ( 16 S) of the lower wall ( 16 ).

2. The connector ( 10 , 40 ) of claim 1 , wherein the water guiding surface ( 23 ) is inclined down into the opening area of the drainage port ( 23 ) from the opening edge of the drainage port ( 21 ).

3. The connector ( 10 , 40 ) of claim 2 , wherein the water guiding surface ( 23 ) is connected at an obtuse angle to the upper surface ( 16 S) of the lower wall ( 16 ).

4. The connector ( 10 , 40 ) of claim 3 , wherein the water guide ( 22 ) has a flow-down surface ( 25 ) extending down from a projecting end of the water guiding surface ( 23 ).

5. The connector ( 10 , 40 ) of claim 4 , further comprising a reinforcement ( 24 ) from a projecting from lower surface of the lower wall ( 16 ) and connected to a lower end part of the water guide ( 22 ).

6. The connector ( 10 , 40 ) of claim 5 , wherein:
the receptacle ( 13 , 43 ) includes a back wall ( 14 , 44 ) connected to a rear end part of the lower wall ( 16 );
the drainage port ( 21 , 45 ) also is open in a lower end part of the back wall ( 14 , 44 ); and
the back wall ( 14 , 44 ) is formed with an auxiliary water guide ( 46 ) projecting down into the opening area of the drainage port ( 21 , 45 ) only from a part of an upper edge ( 45 U) the opening edge of the drainage port ( 21 , 45 ).
