Abstract

The invention discloses a waterproof fast-assembly type direct-current charging base for an electric automobile. The base comprises an upper cover, a metal flange, a shell, a terminal and a rear cover. The shell is integrally designed, and a traditional block assembly structure is replaced; the sealing silica gel ring between the upper cover and the metal flange as well as the sealing silica gel ring between the metal flange and the shell are assembled in an embedded manner; a drain hole is designed in the shell; the terminal is fixed with the shell through the ear-free retainer ring, so thatthe ejection force of the terminal is increased; and the rear cover adopts an open type wire hole design, so that a plurality of long wires can penetrate into the rear cover during assembly, and the assembly link is simplified. The waterproof charging pile has excellent waterproof performance, higher assembly efficiency, lower cost and excellent drainage performance, and has important significancein improving the safety and reliability of the charging pile, prolonging the service life of the charging pile, reducing the failure rate and reducing the maintenance and overhaul cost.

Description

technical field [0001] The invention relates to a charging socket, in particular to a DC charging socket for an electric vehicle. Background technique [0002] Charging is an indispensable link in the use of new energy vehicles. The "Guidelines for the Development of Electric Vehicle Charging Infrastructure (2015-2020)" promulgated by the state clearly states that by 2020, more than 12,000 new centralized charging stations will be added, and decentralized There are more than 4.8 million charging piles to meet the charging needs of 5 million electric vehicles across the country. [0003] The charging socket is the most important part connecting the electric vehicle and the power supply equipment during the charging process of the electric vehicle, and its performance is of great significance for promoting the popularization and application of electric vehicles and the construction of charging infrastructure. At present, there are two kinds of charging sockets, DC and AC, com...
