because the through groove communicated with the wiring hole is formed in the conductive column, one end of the wiring hole of the through groove conductive column is divided into an upper pressing part and a lower pressing part, the rapid fixing of the power line can be realized in actual use, the power line is extended between the upper pressing part and the lower pressing part, then the screw is screwed, the end part of the screw can act on the upper pressing part, and the upper pressing part and the lower pressing part are mutually close to clamp and fix the power line;
the clamping assembly comprises a supporting part fixedly arranged on the sliding column, a pressing part hinged on the sliding column, and a spring with one end connected with the pressing part and the other end connected with the limiting part, wherein limiting grooves are formed in the pressing part and the supporting part, and a meshing part matched with the limiting grooves is arranged on the fuse link.
2. The electric vehicle remote charge diagnostic system of claim 1, wherein: the charging current detection module is a Hall current sensor, and the Hall current sensor is used for detecting current data when the electric vehicle is charged, and judging whether the charging is finished or not according to the transmitted real-time current data by sending the detected data to the big data processing server.
3. The electric vehicle remote charge diagnostic system of claim 1, wherein: the temperature detection module is used for monitoring the temperature in the charging process in real time after being awakened by the awakening module, and uploading detected temperature information to the big data processing server, and the big data processing server is used for generating a temperature gradient change chart according to a time period of 1-2 seconds after processing the temperature information.
4. The electric vehicle remote charge diagnostic system of claim 1, wherein: and the upper pressing part and the lower pressing part are respectively provided with a snap convex tooth.
5. The electric vehicle remote charge diagnostic system of claim 1, wherein: the supporting part and the sliding column are of an integrated structure.
6. The electric vehicle remote charge diagnostic system of claim 1, wherein: the connector is connected with the mounting cylinder through threads.
7. The electric vehicle remote charge diagnostic system of claim 1, wherein: the side of the installation cylinder is provided with an access hole, and the installation cylinder is buckled with an access cover.
