Description

Charging Outlet The present invention relates to a charging outlet, and more specifically, to a charging outlet that is embedded in a vehicle body and coupled to a charging part of an electric vehicle connected to a battery to provide external power. Interest in eco-friendly vehicles has increased to address environmental issues through energy conservation and pollution prevention. Consequently, hydrogen fuel cell vehicles, biodiesel vehicles, and electric vehicles are garnering attention as alternatives to vehicles powered by conventional internal combustion engines. Among these, the field of the most active technological development is the electric vehicle sector, which consists of vehicles that use electricity as their primary driving force. To this end, electric vehicles are equipped with a charging section connected to a battery to receive electrical energy from an external source. In this case, a charging outlet connected to an external power source is integrated into the charging section of the electric vehicle to supply power from the outside. Furthermore, since electric energy is a major energy source managed by the state and presents the problem of difficulty in establishing supply infrastructure, there is a trend to increase the adoption of electric vehicles by installing charging outlets in public places for use by an unspecified number of people. In addition, the charging outlet is an electrical component installed in a public place and used by an unspecified number of people, and high-voltage power is supplied for faster charging, and overheating occurred in the charging outlet due to repeated use. As a result, internal components were damaged due to overheating, causing the charging outlet to become fixed, and if the heat spread to a fire, there was a high possibility of secondary accidents such as the explosion of a high-voltage external power source.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. However, in order not to obscure the essence of the present invention, descriptions of known functions or configurations will be omitted. For the convenience of explanation, the direction in which the outlet terminal is extended is defined as the extension direction, the direction in which multiple connecting parts forming a single electrode are arranged is defined as the stacking direction, and the direction simultaneously perpendicular to the extension direction and the stacking direction is defined as the intersection direction. In addition, the extension direction refers to the direction in which the relay part of the outlet terminal is formed as the front, and the direction in which the connection part is formed as the rear. However, this is for the convenience of explaining the invention, and the direction may be different in actual use.
