Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle charging equipment, in particular to an electric vehicle charging control box. Background Art

[0002] As energy and environmental issues become increasingly prominent, electric vehicles are developing rapidly, and the corresponding demand for electric vehicle charging is also increasing rapidly. In order to facilitate electric vehicle charging, many electric vehicles are equipped with portable electric vehicle charging control boxes. The electric vehicle charging control box is a common accessory for charging electric vehicles. The electric vehicle charging control box belongs to the shell product. According to the requirements of the car manufacturer, it needs to meet a certain level of protection. It is generally equipped with two charging cables, of which the first charging cable is connected to the charging port of the car, and the second charging cable is connected to the external power supply. The first charging cable and the second charging cable are connected through a circuit board.

[0003] Technical personnel engaged in this industry have found that for general charging control boxes, when the protection level is met, the charging cable is difficult to access the control box due to the resistance of the wire sheath fixed to the control box shell, resulting in low assembly efficiency. In addition, since the waterproof performance of the electric vehicle charging control box is insufficient, water easily enters in rainy and snowy weather, causing a short circuit between the circuit board and the first charging cable or the second charging cable, causing a safety accident. For this reason, we propose an electric vehicle charging control box. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that, when a general charging control box is connected to the control box with a protection level met, the cable entry is difficult due to the resistance of the wire sheath fixed to the control box shell, resulting in low assembly efficiency. In addition, since the waterproof performance of the electric vehicle charging control box is insufficient, water easily enters in rainy and snowy weather, resulting in a short circuit between the circuit board and the first charging cable or the second charging cable, causing a safety accident. The utility model provides an electric vehicle charging control box.

[0007] Furthermore, the vertical cross-sectional dimension of the mounting groove is consistent with the vertical cross-sectional dimension of the charging control box.

[0008] Furthermore, the internal thread formed inside the connection hole is consistent in size with the external thread formed on the circumferential surface of the fixing ring.

[0009] Furthermore, a waterproof pad is installed between the fixing ring and the first charging cable and the second charging cable.

[0010] Furthermore, the vertical cross-sectional dimension of the limiting block is consistent with the vertical cross-sectional dimension of the limiting groove.

[0011] Furthermore, the diameter of the fixing column is consistent with the width of the limiting groove.

[0012] Furthermore, the diameter of the limiting column is consistent with the diameter of the limiting hole.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. When the utility model is in use, the first charging cable and the second charging cable are installed in the connecting port opened on the charging control box, and then the first charging cable and the second charging cable are connected to the charging pile and the electric vehicle respectively.
