Problems solved by technology

However, when the liquid-cooled cable is applied to the charging gun, the connection between the liquid-cooled cable and the pins is not firm, causing the liquid-cooled cable to shake easily, causing the coolant in the liquid-cooled cable to flow out from the connection between the two, reducing the liquid The heat dissipation effect of the cold cable further reduces the current-carrying capacity of the charging gun, resulting in the charging gun not being able to charge the electric vehicle with high power

Abstract

The invention provides a contact pin, a connection structure of the contact pin and a liquid cooling cable and a charging gun with the contact pin. The contact pin is used for connecting the liquid cooling cable to the charging gun and comprises a contact pin body, one end of the contact pin body is axially and sequentially provided with a first storage groove and a second storage groove, the first storage groove is communicated with second storage groove, and the diameter of the first storage groove is larger than that of the second storage groove. Reliability and stability in connection between the contact pin and the liquid cooling cable can be guaranteed, and heat generated in charging operation of the contact pin can be quickly taken away through the liquid cooling cable, so that the contact pin can be cooled reliably, and current carrying capacity of the charging gun can be improved to realize high-power charging of electric devices (such as electric vehicles).

Description

technical field [0001] The invention relates to the technical field of charging guns, in particular to a pin, a connection structure between the pin and a liquid-cooled cable, and a charging gun using the pin. Background technique [0002] When using a charging gun to charge an electric vehicle with high power, the cable of the charging gun will generate heat, which poses a safety hazard. Generally, the heat dissipation effect of the cable can be improved by increasing the cross-sectional area of ​​the conductor in the cable. However, the increase in the cross-sectional area of ​​the conductor will lead to a decrease in the flexibility of the cable and reduce the service life of the cable. [0003] Liquid-cooled cables have better heat dissipation. However, when the liquid-cooled cable is applied to the charging gun, the connection between the liquid-cooled cable and the contact pin is not firm, causing the liquid-cooled cable to shake easily, causing the coolant in the li...
