An electric vehicle charging connector

Abstract

The invention relates to an efficient charging connector of an electric automobile. The efficient charging connector comprises a bearing base, a bearing keel, wire winding wheels, wire winding drive mechanisms, charging buses, wiring terminals, current-limiting fuses, an overload protecting circuit, a charging and discharging controller and a comprehensive control circuit, wherein the current-limiting fuses, the overload protecting circuit, the charging and discharging controller and the comprehensive control circuit are all embedded into the bearing base, the bearing keel is hinged to the upper end face of the bearing base, the wire winding wheels are embedded into the bearing keel, one end of each wire winding wheel is connected with the corresponding wire winding drive mechanism througha transmission shaft, the charging buses are wound on of the wire winding wheels, and the two ends of the charging buses are electrically connected with the wiring terminals. On the one hand, flexibility and convenience of charging operation are greatly improved, on the other hand, a charging operation part and a charging circuit are effectively insulated and isolated, the state in the charging process is effectively controlled and managed, and therefore safety and reliability of charging operation are greatly improved.

Description

technical field [0001] The invention relates to a charging device, in particular to a charging connector for an electric vehicle. Background technique [0002] At present, in the process of charging electric vehicles, both the charging pile and the on-board backup charger need to be connected to the external power supply through the charging connector line for charging operations. However, it is found in use that the current overcharging connector line equipment is often Based on the traditional direct connection between the plug and the charging busbar, although it can meet the needs of use, it often lacks effective circuit protection capabilities during charging operations, which leads to extremely serious failures such as short circuits and other circuit overloads and excessive currents during charging. It is easy to cause damage to the charging power supply equipment and electric vehicles, and even cause fires in serious cases. In addition, the structure of the current o...

[0002] At present, in the process of charging electric vehicles, both the charging pile and the on-board backup charger need to be connected to the external power supply through the charging connector line for charging operations. However, it is found in use that the current overcharging connector line equipment is often Based on the traditional direct connection between the plug and the charging busbar, although it can meet the needs of use, it often lacks effective circuit protection capabilities during charging operations, which leads to extremely serious failures such as short circuits and other circuit overloads and excessive currents during charging. It is easy to cause damage to the charging power supply equipment and electric vehicles, and even cause fires in serious cases. In addition, the structure of the current overcharging connector circuit equipment is fixed, especially the effective charging distance is relatively fixed, so it cannot be used according to the needs of charging. , flexibly adjust the charging angle, position, etc., which seriously affects the convenience and efficiency of charging operation. At the same time, the current insulation protection of the overcharging connector line is only realized by the insulation layer covering the plug, so the insulation protection level is relatively low. When In the event of an accident such as leakage, the operator cannot be effectively insulated and protected, which seriously threatens the personal safety of the operator. Therefore, in view of this situation, it is urgent to develop a new electric vehicle charging gun device to meet the needs of actual use.
