Charging socket of electric vehicle

Abstract

The invention relates to a charging socket, which has the effects of power-off protection when an electric vehicle is charged and short-circuit protection when the electric vehicle is not charged. Thecharging socket comprises a shell, the middle of the shell is sunken to form a plug groove for allowing a plug to be attached and clamped in, a positive pole insertion piece, a negative pole insertion piece and a power-off insertion piece which are attached to and inserted into the plug are arranged in the plug groove, and the positive pole insertion piece and the negative pole insertion piece are communicated with the positive pole and the negative pole of a storage battery respectively; wherein the power-off insertion piece is made of an insulating material, accommodating grooves are respectively formed in two sides of the power-off insertion piece, conducting strips are arranged in the accommodating grooves in an attached manner, the two conducting strips are respectively communicatedwith a controller through electric wires, and transformers for converting voltage into at least 12V are arranged on the electric wires. Power-off protection during charging of the electric vehicle isachieved by means of cooperation of the power-off insertion piece and the controller.

Description

technical field [0001] The invention relates to a charging socket, more specifically, it relates to a charging socket for an electric vehicle. Background technique [0002] The electric vehicle charging socket is generally installed on the shell of the electric vehicle decoration, which is convenient for the connection of the charger and the electric vehicle battery. However, if there is any metal material in the exposed charging socket, a short circuit is likely to occur. It is often reported that a child accidentally pokes a coin or metal material into the charging socket of an electric vehicle and causes a short circuit. [0003] The patent of announcement number CN204720666U and publication date 20151021 discloses a smart charging socket for electric vehicles, including a socket body, an openable and closable waterproof cover is provided above the interface of the socket body, and a negative electrode is provided inside the socket body. The insert and the positive inser...

Problems solved by technology

However, this kind of charging socket still needs to be installed with a miniature normally closed switch. Since the reset of the normally closed switch is mainly realized by the spring, it takes a long time to charge the electric vehicle. After working for a long time, the spring cannot return to its original state, causing the normally closed switch to fail to work normally, and there is a problem of short service life
