Plug-in assembly, short circuit withstanding circuit and electric vehicle

Abstract

The invention provides a plug-in assembly, a short circuit withstanding circuit and an electric vehicle. The plug-in assembly comprises a socket and a plug, and is characterized in that the socket comprises a first bracket, a first magnetic ring and a first conductive structure, wherein an assembling hole is formed inside the first bracket, the first magnetic ring is arranged in the assembling hole, the first conductive structure is arranged in the assembling hole and comprises a first pole conductive structure and a second pole conductive structure, the first pole conductive structure is disposed in a center region of the assembling hole, and the second pole conductive structure is disposed in a circumferential region of the assembling hole; and the plug comprises a second magnetic ring and a second conductive structure, wherein the first conductive structure and the second conductive structure are brought into contact with each other through attraction of the first magnetic ring and the second magnetic ring when the socket and the plug are assembled in a matched manner. According to the embodiment of the invention, the plug can be attracted into the socket when the plug and the socket are close to each other, and the plugging accuracy and safety are improved by being matched with the first pole conductive structure and the second pole conductive structure, so that a circumstance of reverse connection of positive and negative electrodes between the socket and the plug is effectively reduced, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a plug assembly, an anti-short circuit and an electric vehicle. Background technique [0002] At present, when charging an electric vehicle, it is necessary to align the plug with the socket and press it down hard, which brings great inconvenience to the user, especially at night when the light is weak, because the position of the socket cannot be seen, it is very difficult to It is difficult to insert the plug directly into the socket, and it is easy to be dangerous if the socket and plug are reversed. [0003] The voltage at both ends of the electric vehicle battery is an unsafe voltage. Because the positive and negative terminals of the electric vehicle battery are exposed, it is easy to cause electric shock. If metal foreign objects enter, it will cause severe ignition or even burn the car, which poses a great safety hazard. Contents of the invention [0004] The present i...

[0003] The voltage at both ends of the electric vehicle battery is an unsafe voltage. Since the positive and negative terminals of the electric vehicle battery are exposed, it is easy to cause an electric shock. If any metal foreign matter enters, it will cause severe ignition or even burn the car, which poses a great safety hazard.
