Electric vehicle charging plug and socket assembly

Abstract

An electric vehicle charging plug and socket assembly disclosed by the invention comprises a plug assembly and a locking assembly. The plug assembly comprises a shell, a PIN group, a fixing block for fixing the PIN group, a connector and a conductive wire, the locking assembly comprises a locking switch and a pressing switch, and the locking switch is rotatably installed on the shell of the plug assembly. The pressing switch is connected with a conductive wire and a conductive sheet in the plug assembly, the conductive sheet is connected with an external cable, the pressing switch can connect the conductive sheet with the conductive wire only when the locking switch is placed at a specified position, and in addition, the inner cavity of the pressing switch is provided with the isolation chamber for isolating the conductive wire from the contact of the conductive sheet so that electric arcs are prevented from being generated. Good safety performance is realized.

Description

technical field [0001] The invention relates to an electric vehicle charging plug and socket assembly, which belongs to the technical field of cables and wires. Background technique [0002] With the popularization of electric vehicles, charging equipment and charging equipment accessories have undergone new innovations. Charging plugs are one of the indispensable products in charging equipment. They are tools for connecting electrical equipment and power sources. In addition to the power supply function, safety is more important. It is precisely because of safety considerations to prevent arcing at the moment of power on, so the charging plug on the market adopts a locking structure. It is more common to power on after the connection is confirmed. The best is to use a contact switch, which is triggered by pressing, but this locking structure only needs to be pressed once, and the safety performance is still not enough, and there may be false touches. In addition, it has bee...

[0002] With the popularity of electric vehicles, charging equipment and charging equipment accessories have undergone new innovations. Charging plugs are one of the indispensable products in charging equipment. They are tools for connecting electrical equipment and power sources. In addition to the power supply function, safety is more important. It is precisely because of safety considerations to prevent arcing at the moment of power on, so the charging plug on the market adopts a locking structure, and it is more common to power on after the connection is confirmed. The best is to use a contact switch, which is triggered by pressing, but this locking structure only needs to be pressed once, and the safety performance is still not enough, and there may be false touches. In addition, it has been found in practice that even if the locking mechanism is adopted, Due to the imperfect handling of internal details, the product still has arcing.
