Description

Technical Field

[0001] This utility model relates to the field of battery swapping connector technology, and in particular to a connector for charging and swapping new energy vehicles. Background Technology

[0002] With the rapid development of the electric vehicle industry, more and more electric vehicle battery swapping stations are being set up in cities. In the application scenarios of electric vehicle battery swapping stations, the battery swapping connector is a very important component. Frequent plugging and unplugging can easily damage it, and its reliability directly affects the reliability of the entire electric vehicle battery swapping station.

[0003] Battery swapping connectors are typically designed for complete vehicles, and their mating life is usually several thousand cycles. For a complete vehicle, several thousand mating cycles are sufficient to last its entire lifespan. However, for electric vehicle battery swapping stations, the lifespan of the battery swapping connectors quickly reaches its limit due to the increasing number of battery swaps, at which point the battery swapping connectors must be replaced.

[0004] In existing technologies, the high-voltage electrode, as a key component for current transmission, carries a large current for extended periods, leading to increased temperature and insufficient heat dissipation. This affects the stability and conductivity of the connection point with the conductor. Furthermore, the high temperature at the contact area between the high-voltage electrode and the high-voltage conductive needle can cause increased contact resistance and arcing, further impacting the safety and efficiency of the battery swapping process. Therefore, the applicant has developed a beneficial design and found a solution to these problems. The technical solution described below arose from this context. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the traditional battery swapping connector design and provide a product that controls temperature rise and ensures long-term stable operation.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A connector for charging and swapping new energy vehicles includes a connector housing, a signal connection terminal inside the connector housing, high-voltage terminals located on both sides of the signal connection terminal inside the connector housing, a protective part for wrapping the high-voltage terminals on the back of the connector housing, a heat-conducting sleeve inside the protective part and fitted onto the outer wall of the high-voltage terminals, a plurality of equally spaced heat-conducting parts on the inner wall of the heat-conducting sleeve and embedded in the outer wall of the high-voltage terminals, and a plurality of heat dissipation fins evenly distributed along the circumferential direction on the outer wall of the heat-conducting sleeve and passing through the protective part.

[0008] Preferably, the connector housing has a recessed cavity for accommodating the signal connection terminal and the high-voltage pole, and guide grooves are provided on both sides of the recessed cavity.

[0009] Preferably, the cavity is provided with a grounding electrode and is located between one of the high-voltage electrodes on one side of the signal connection terminal.

[0010] Preferably, the cavity is provided with a pressure plate for pressing the signal connection terminal, high voltage terminal, and grounding terminal into the cavity.

[0011] Preferably, the high-voltage electrode is provided with a heat-conducting groove to accommodate the heat-conducting part.

[0012] Preferably, thermal grease is provided between the thermally conductive sleeve and the high-voltage electrode, and between the thermally conductive part and the thermally conductive groove.

[0013] Preferably, the outer wall of the heat-conducting sleeve is provided with a plurality of flow channels evenly distributed along the circumferential direction and disposed between adjacent heat dissipation fins.

[0014] Beneficial effects:

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention expands the contact area between the heat-conducting sleeve and the high-voltage electrode by increasing the heat-conducting part, thereby improving heat conduction efficiency. The heat dissipation fins simultaneously increase the contact area with air, enhancing heat exchange capacity. The guide groove structure further expands the contact range between the heat-conducting sleeve and the air, preventing heat accumulation at the bottom of the protective part and improving overall heat exchange performance. The above structural design effectively controls the temperature rise of the high-voltage electrode, preventing unstable contact and decreased conductivity at the connection point due to high temperature, thus ensuring the safety and efficiency of the battery swapping process. This design improves thermal management capabilities, enhances the stability of the high-voltage electrode under high current conditions, reduces the risk of electrical performance degradation caused by temperature rise, and optimizes the heat dissipation structure to help extend the overall service life of the connector, improving the reliability and continuous operation capability of the battery swapping process.
