Vehicle-side connector with water drainage paths extending from an outwardly open recess
A vehicle-side connector ( 10 ) to be connected to a charging connector in charging a battery of a vehicle includes a receptacle ( 33 ) which is connectable to the charging connector, a mounting portion ( 31 ) which is provided to partition between the receptacle ( 33 ) and a vehicle (B) and to be fixed to the vehicle, a recess ( 40 ) which is open upward and provided on the top of the connecting portion ( 33 ), and water drainage paths ( 41 ) formed in inner surfaces of the recess ( 40 ) without penetrating through the mounting portion ( 31 ).
1. A vehicle-side connector to be connected to a charging connector when charging a battery of a vehicle, comprising:
a tubular connecting portion having a front end for receiving the charging connector, a rear end opposite the front end and an outer peripheral surface extending rearward from the front end, the connecting portion being sloped so that the front end is higher than the rear end;
a mounting flange projecting out from the outer peripheral surface of the connecting portion rearward of the front end;
an engaging portion projecting out from a top side of the outer peripheral surface of the connecting portion and spaced forward of the mounting flange;
side walls extending toward the mounting flange from opposite sides of the engaging portion so that an outwardly open recess is defined by the side walls, the engaging portion and the mounting flange, the side walls being spaced from the mounting flange to define water drainage paths from the recess.
2. The vehicle-side connector of claim 1 , wherein the recess is open upward and is on or near the top of the connecting portion.
3. The vehicle-side connector of claim 1 , wherein surfaces of the side walls facing each other define inner surfaces of the recess.
4. The vehicle-side connector of claim 1 , wherein the connecting portion ( 33 ) is engageable with a lock (L) on the charging connector in a connecting direction.
5. The vehicle-side connector of claim 4 , wherein a bottom surface of the recess is arranged at a position to contact the lock when the lock and the engaging portion are engaged; and
at least one recessed groove lower than the bottom surface of the recess is formed between the water drainage paths and an end of the recess adjacent the mounting flange.
6. The vehicle-side connector of claim 1 , wherein the water drainage path is defined by a front surface of the mounting flange, a rear end surface of the protection wall and an outer surface of the receptacle.
7. The vehicle-side connector of claim 6 , wherein the water drainage path is formed over substantially the entire height of the protection wall.
8. The vehicle-side connector of claim 1 , wherein a depth of the recess is substantially equal to a projecting distance of the engaging portion from a distal end of the receptacle, and wherein a bottom surface of the recess is at a position so that a distal end of a tip of a lock provided on the charging connector substantially comes into contact therewith.
9. The vehicle-side connector of claim 1 , further comprising at least one positioning recess projecting radially outward is provided at the connecting portion in a position substantially opposite to that of the recess and the engaging portion.
10. The vehicle-side connector of claim 1 , further comprising a recessed groove in the outer peripheral surface of the connecting portion and extending between the water drainage paths.
