Description:TECHNICAL FIELD
[001] The present disclosure relates to electric vehicles (EVs), more particularly relates to charging connectors used to charge the battery of an electric vehicle.

BACKGROUND
[002] Electric vehicles have seen significant advancements in recent years, and charging infrastructure has played a crucial role in their widespread adoption. Charging connectors are vital components that facilitate the transfer of electric energy from charging stations to the EV battery. These connectors are subjected to various environmental factors and operating conditions, which can impact their overall performance and durability.
[003] Further in an electric vehicle, an electric motor is driven by high voltage battery and the battery is charged through a charging connector. A charging connector installed in a vehicle is called a socket connector into which a charging plug is connected and disconnected for power supply.
[004] The socket connector is mounted on the vehicle vertically up facing the sky. When the vehicle is parked in open area, the rain water may enter between the gap of the body panel and get accumulated into the upper part of the socket connector.
[005] If the socket connector is not erected in the direction of gravity and is installed in a vehicle with a certain degree of inclination to the direction of gravity, the water that has flowed into the upper part of the socket connector is not drained outside and accumulates, causing a short circuit when the plug is connected to socket connector for charging.
[006] Further certain charging connector and socket connector in the vehicle have a fluid line in addition to the power line to maintain the temperature. During disconnection left over fluid may spill over the socket or the charging connector. The accumulation of fluids may result in corrosion on the connectors.
[007] Therefore, there is a need of a system for discharging this accumulated water or fluid that alleviates the aforementioned drawbacks.

OBJECTS OF THE INVENTION
[008] The principal object of the present disclosure is to prevent accumulation of fluids inside a charging socket of an electric vehicle (EV).
[009] Another object of the present disclosure is to provide an innovative socket design housing.
[0010] Another object of the present disclosure is to provides a socket housing having drain cut-out on periphery of the socket.
[0011] Yet another object of the present disclosure is to prevent ingress of water when both socket and plug are connected for charging.

SUMMARY
[0012] This summary is provided to introduce concepts related to a charging socket configured to prevent accumulation and ingress of fluids inside the charging socket of an electric vehicle (EV). This summary is not intended to identify essential features of the claimed subject matter nor is it intended for use in limiting the scope of the claimed subject matter.
[0013] In an implementation of the present disclosure a charging socket 100 is disclosed. The charging socket 100 may comprise a socket housing 102.
