The electrical connector 100 also includes a first liquid guide tube 30 , both ends of the first liquid guide tube 30 communicate with the receiving cavity 11 , and the cooling medium circulates in the first liquid guide tube...

Abstract

The embodiment of the invention relates to the technical field of electric energy transmission, in particular to an electric connector, a charging pile and a charging system. The electric connector comprises a shell, a joint and a cooling medium, the shell is provided with an accommodating cavity and two oppositely arranged through holes, and the accommodating cavity is communicated with the outside through the through holes. The connector comprises a first part and second parts, the second parts are arranged at the two ends of the first part, the connector is inserted into the shell, the first part is located in the containing cavity, the second parts penetrate out of the through hole and are exposed out of the outer surface of the shell, and the first part is subjected to insulation treatment and heat conduction treatment. The cooling medium is contained in the containing cavity. Through the above structure, after the first part is subjected to surface treatment, excellent insulation and heat conduction effects can be obtained, so that after the joint generates heat, heat is directly dissipated through a cooling medium. Meanwhile, electric leakage of the connector can be effectively prevented after insulation treatment. Therefore, the transmission efficiency of electric energy is improved.

[0047] Test summary:

[0048] Please also refer to Table 1 above and Figures 6 to 9 , in conjunction with other drawings. From the comparison of the test data in Table 1, it can be seen that the coolant temperatures in the corresponding areas at (1) and (6) and (2) and (7) are basically the same, while comparing the data at other points in Table 1, this The temperature of the cooling liquid in the application example is lower than the temperature of the cooling liquid in the comparative example. That is, the temperature at point (8) on the joint 20 in the embodiment of the present application is 14.1°C lower than the temperature at point (3) on the comparative example; the temperature at point (9) on the joint 20 in the embodiment of the present application Compared with the temperature at point (4) on the comparative example, the temperature of the junction is reduced by 9.9°C; the temperature at point (10) on the joint 20 in the embodiment of the present application is reduced by 10.7°C compared with the temperature at point (5) on the comparative example. °C, an average decrease of about 11.57 °C. That is, at this point, the temperature of the joint in the example of the present application is lower than that in the comparative example. In conclusion, compared with the comparative example, the example of the present application has lower thermal resistance, higher heat exchange rate, and better heat dissipation effect.
