Electric vehicle charging gun plug connector

Abstract

The invention provides a charging gun type connection-peg for an electric automobile. The charging gun type connection-peg comprises a female plug, a male plug and a tightening device and is characterized in that, according to the female plug, a coil is wound on a female plug coil winding shell, the female plug coil winding shell is mounted in a female plug coil sealing shell, and the coil, the female plug coil sealing shell and the female plug coil winding shell are sleeved on a female plug magnetic core; according to the male plug, a coil is wound on a male plug coil winding shell, the male plug coil winding shell is mounted in a male plug coil sealing shell, and the coil, the male plug coil sealing shell and the male plug coil winding shell are sleeved on a male plug magnetic core; and when the female plug and the male plug are closed and tightened, the female plug magnetic core and the male plug magnetic core form a closed magnetic circle.

Description

technical field [0001] The invention relates to a power supply plug joint, in particular to an electric vehicle charging gun type plug joint used for alternating current and having a voltage transformation function. Background technique [0002] At present, the power plug connectors on the market are in direct contact with the metal sheets of the plug connectors during the live plugging and unplugging process, and arcs will occur. The size of the overcurrent is related to the area of ​​each metal sheet contact, and this contact area cannot be controlled. Yes, false contact will not only cause arcing but also increase the resistance value, it will not be waterproof, and it will cause personal safety accidents if it is connected to electricity when it is in contact with water. Invented a new electric vehicle charging gun type plug connector that can realize more convenient and flexible plugging, more convenient production and assembly, stable over-current, waterproof, no arc, ...
