Abstract

A combined charging inlet ( 10 ) including plural connector fitting portions that are integrated, including: an inlet housing ( 20 ) including a first hood ( 50 ) and a second hood ( 60 ) that are provided integrally and continuously with each other. First drains ( 34 A) to ( 34 C) configured to drain water from first cavities ( 32 A) to ( 32 C) that accommodate first terminals ( 31 A) to ( 31 C) in a first connector fitting ( 30 ) to a first drain space ( 33 ). A first water guide ( 51 ) guides water from the first drain space ( 33 ) to a second drain space ( 43 ). Second drains ( 44 A) and ( 44 B) drain water from second cavities ( 42 A) and ( 42 B) that accommodate second terminals ( 41 A) and ( 41 B) in a second connector fitting ( 40 ) to the second drain space ( 43 ), and a second water guide ( 61 ) guides water from the second drain space ( 43 ) to outside of a vehicle.

First claim

What is claimed is:

1. A combined charging inlet including a plurality of integrated connector fittings, comprising:
an inlet housing including a first hood disposed around a first connector fitting and outside of a vehicle, and a second hood disposed around a second connector fitting located below the first connector fitting and outside of the vehicle, the first connector fitting and the second hood being provided integrally and continuously with each other;
a first drain configured to drain water from a first cavity that accommodates a first terminal in the first connector fitting to a first drain space formed between an outer peripheral surface of the first connector fitting and an inner peripheral surface of the first hood;
a first water guide configured to guide water from the first drain space to a second drain space formed between an outer peripheral surface of the second connector fitting and an inner peripheral surface of the second hood;
a second drain configured to drain water from a second cavity that accommodates a second terminal in the second connector fitting to the second drain space; and
a second water guide configured to guide water from the second drain space to outside of the vehicle.

2. The combined charging inlet of claim 1 ,
wherein the first connector fitting is formed separately from the inlet housing and is configured to be mounted fixedly to a mounting hole formed in the inlet housing from a rear in a fitting direction, and an O-ring is sandwiched between the outer peripheral surface of the first connector fitting and an inner peripheral surface of the mounting hole.

3. The combined charging inlet of claim 1 ,
wherein the second drain includes a second drain hole formed between an inner peripheral surface of the second cavity and the outer peripheral surface of the second connector fitting, a mold removal hole that causes the second drain hole to face rearward in the fitting direction, and a rubber stopper that is mounted to the mold removal hole from the rear in the fitting direction so as to seal an inside of the vehicle and define the second drain hole.

4. The combined charging inlet of claim 1 ,
wherein the first drain includes a first drain hole formed between an inner peripheral surface of the first cavity and the outer peripheral surface of the first connector fitting.

5. The combined charging inlet of claim 1 ,
wherein the first water guide includes a first water guide hole formed between the inner peripheral surface of the first hood and the inner peripheral surface of the second hood, and the first water guide hole is open forward in the fitting direction.
