Description

Charging connector Technical Field The present disclosure relates to charging connectors. Background A charging connector is mounted on a vehicle such as an electric vehicle, and the charging connector is connected to an external charging connector on the electric pile side to receive charging. The connection portion between the charging connector and the external charging connector is provided with a connection terminal. As such a charging connector, an apparatus as described in patent document 1 is known. The charging connector described in patent document 1 includes a cylindrical portion fitted to an external charging connector. A plurality of terminals electrically connected to the terminals of the external charging connector are provided inside the cylindrical portion. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2020-83130 Disclosure of Invention Problems to be solved by the invention Here, when the electric wire extending from the terminal becomes thick, it is difficult to bend. In this case, it is desirable that the electric wire which is difficult to bend is prevented from interfering with the exterior member (e.g., protector, grommet), and can be routed inside the exterior member. Accordingly, it is an object to provide a charging connector capable of avoiding interference of an electric wire with respect to an exterior member and capable of disposing the electric wire in the exterior member. Means for solving the problems The disclosed charging connector is mounted on a vehicle, and is configured to be inserted into and removed from the charging connector by an external charging connector connected to an external power supply of the vehicle, wherein the charging connector is configured to be used for charging a battery provided in the vehicle, and is provided with a plurality of 1 st terminals, a2 nd terminal thicker than the 1 st terminals, a housing body having an opening portion into which the external charging connector is inserted and removed, and a plurality of terminal receiving portions that are positioned inside the opening portion when viewed in a direction in which the external charging connector is inserted and removed, and that receive the 1 st terminals and the 2 nd terminals, a stopper body that is mounted on an end portion on the opposite side of the opening portion with respect to the terminal receiving portions, and that holds the 1 st terminals and the 2 nd terminals together with the housing body, a plurality of 1 st wires that are electrically connected to the 1 st terminals, a2 nd wire that is electrically connected to the 2 nd terminal, and thicker than the 1 st wire, a wire holding portion that is positioned on the inner side of the opening portion when viewed in the direction of the external charging connector, and a wire holding portion that is positioned in the direction in which the first terminal and the 2 nd wire are bent away from the opening portion, and a length of the first wire holding portion is positioned in a direction in which the length direction of the first wire and the 2 nd wire is bent from the first terminal 2 nd wire is bent, and the length of the first wire holding portion is positioned in a direction opposite to the direction from the first terminal 2 nd wire.
