Description

BACKGROUND OF THE INVENTION Field of the Invention Embodiments of the present invention relate to a charging inlet. Priority is claimed on Japanese Patent Application No. 2024-192756 filed in Japan on November 1, 2024, the content of which is incorporated herein by reference. Description of the Related Art In the related art, a connector installed in a vehicle has been proposed in order to supply (charge) electric power from the outside of the vehicle to a battery mounted on the vehicle such as an electric vehicle or a plug-in hybrid vehicle (see, for example, Patent Document 1). This type of connector is also generally referred to as a charging inlet. The charging inlet is provided with a drain path for draining water that has entered a housing. Prior Art Document Patent Document Patent Document 1: Japanese Unexamined Patent Application, First Publication No. 2023-127174 SUMMARY OF THE INVENTION Meanwhile, in the charging inlet, a constitution for further improving a drain property of the housing is expected. An embodiment provides a charging inlet with an improved drain property of a housing. A charging inlet of an embodiment includes a housing to and from which a charging plug is attachable and detachable and which holds a connection terminal inside, wherein the housing includes a fitting recess to and from which the charging plug is attached and detached, and a drain path extending from an inside of the fitting recess to an outside of the housing, wherein the drain path includes a drain passage extending in a horizontal direction in a state where a device to which the charging inlet is attached is on a horizontal plane, and wherein the drain passage has drain ports opened to the outside of the housing at both end portions in a length direction of the drain passage. According to an embodiment, it is possible to provide a charging inlet with an improved drain property of a housing.
