[0002] New energy vehicles are gaining an increasingly larger share of the market and are becoming more and more attractive to consumers. These vehicles primarily use electricity and require charging stations, which in turn require electrical connectors to connect to the vehicles. Current electrical connectors generally consist of a male terminal and a female terminal; one is located on the vehicle body, and the other connects to the charging station. Existing connectors primarily rely on friction between the male and female terminals to achieve connection. This method suffers from poor stability, and the connector is prone to loosening, affecting charging efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a highly stable electrical connector for new energy vehicles, in order to solve the problems of poor stability and easy loosening of electrical connectors in the prior art, which affect the charging effect.

[0004] To achieve the above objectives, the present invention provides a high-stability electrical connector for new energy vehicles, employing the following technical solution: A high-stability electrical connector for new energy vehicles includes a male connector and a female connector. The male connector is provided with pins, and the female connector is provided with sockets adapted to the pins. The male connector is used to be mounted on the body of a new energy vehicle, and the female connector is used to connect to a charging pile. A connection structure is provided between the male connector and the female connector. The connection structure includes a connecting sleeve that slides along the female connector. A first limiting structure and a second limiting structure are provided on the female connector along the sliding path of the connecting sleeve. The first limiting structure presses the female connector against the male connector, and the second limiting structure prevents the connecting sleeve from falling off. A magnetic attraction structure is provided between the male connector and the end of the connecting sleeve facing the male connector.

[0005] The magnetic attraction structure includes a rubber ring magnet disposed on the male end of the connector, and multiple permanent magnets are disposed at circumferential intervals on the end of the connector sleeve facing the male end of the connector.

[0006] The male connector includes a base plate and a male protrusion on the base plate. The male protrusion has a groove. A rubber ring magnet is disposed on the base plate, and a pin is disposed on the bottom of the groove. The female connector has an insertion section that inserts into the groove, and a socket is disposed on the end face of the insertion section. The connector sleeve can be fitted onto the outside of the male protrusion under the action of the magnetic attraction structure.

[0007] A first sealing ring is provided on the end face of the connecting sleeve facing the male end.

[0008] The end of the connecting sleeve facing the male end of the connecting sleeve is provided with an annular protrusion, and the first sealing ring is provided on the annular protrusion. The first sealing ring is located inside the circle where the permanent magnet is located.

[0009] The first limiting structure includes a first step disposed on the connecting female end, and a second step disposed on the connecting sleeve to limit the first step.

[0010] The second step is provided with a second sealing ring for sealing and engaging with the first step.

[0011] The second limiting structure includes a limiting protrusion disposed on the connecting female end, which is used to cooperate with the second step limiting on the connecting sleeve to prevent the connecting sleeve from falling off.

[0012] A nut is threaded onto the female connector, and the nut forms the limiting protrusion.

[0013] The beneficial effects of this utility model are as follows: After the male and female terminals are connected together, the male and female terminals are fixed together by sliding the connecting sleeve towards the female terminal through the first limiting structure and the magnetic attraction structure, which can increase the stability of the connection between the two, making them less likely to loosen and ensuring the charging effect.

[0014] Furthermore, the connecting sleeve, under the action of the magnetic structure, can be fitted onto the outside of the male protrusion, thus providing a rainproof effect. Attached Figure Description

The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0019] It should be noted that, unless otherwise defined, the technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The use of "belonging" in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this invention.

[0020] An embodiment of this utility model of a high-stability electrical connector for new energy vehicles, such as... Figures 1-3 As shown, the device includes a male connector 1 and a female connector 2. The male connector 1 is provided with a pin 6, and one end of the female connector 2 is provided with a socket 17 that matches the pin, while the other end is connected to a cable 11. In this embodiment, the male connector 1 is used to be mounted on the new energy vehicle body, and the female connector 2 is used to connect to a charging pile. In other embodiments, the male connector can also be used to connect to a charging pile, and the female connector can be mounted on the new energy vehicle body.

[0021] In this embodiment, a connecting structure is provided between the male end 1 and the female end 2. Specifically, the connecting structure includes a connecting sleeve 9 that slides along the female end, and a first limiting structure and a second limiting structure are provided on the female end 2 along the sliding path of the connecting sleeve. The first limiting structure cooperates with the connecting sleeve to press the female end against the male end, and the second limiting structure prevents the connecting sleeve from falling off. The first limiting structure includes a first step 14 provided on the female end, and a second step 12 provided on the connecting sleeve to cooperate with the first step. The second limiting structure includes a limiting protrusion 10 provided on the female end, which cooperates with the second step on the connecting sleeve to prevent the connecting sleeve from falling off. In this embodiment, a nut is threaded onto the female end, and the nut forms the aforementioned limiting protrusion 10.

[0022] A magnetic attraction structure is provided between the male connector and the end of the connecting sleeve facing the male connector. The magnetic attraction structure includes a rubber ring magnet 7 disposed on the male connector, and multiple permanent magnets 15 spaced circumferentially along the end of the connecting sleeve facing the male connector. Under the action of the magnetic attraction structure, the connecting sleeve can be fitted onto the outside of the male connector protrusion. The advantage of this arrangement is that it not only achieves a stable connection between the connecting sleeve and the male connector, but also provides rain protection. Specifically, the male connector 1 includes a base plate 3 and a male connector protrusion 4 disposed on the base plate. The male connector protrusion has a groove 5, the rubber ring magnet 7 is disposed on the base plate 3, and the pin 6 is disposed on the bottom of the groove 5. The female connector 2 has an insertion section that inserts into the groove, and a socket 17 is disposed on the end face of the insertion section. A first sealing ring 16 is provided on the end face of the connecting sleeve facing the male end. Specifically, an annular protrusion 13 is provided on the end face of the connecting sleeve facing the male end, and the first sealing ring 16 is disposed on the annular protrusion 13. The first sealing ring 16 is located inside the circle containing the permanent magnet 15. A second sealing ring 17 is provided on the second step 12 for sealing and engaging with the first step 14. The first sealing ring 16 and the second sealing ring 17 can prevent rainwater from entering. For example, the first sealing ring can prevent rainwater flowing down the vehicle body from entering, and the second sealing ring can prevent rainwater flowing down the cable from entering.

[0023] During use, insert the female connector into the male connector, connecting the socket and the pin. After connection, slide the connecting sleeve close to the male connector. The magnetic structure then secures the sleeve to the female connector. At this point, the second step on the sleeve engages with the first step, pressing against the second sealing ring. The annular protrusion on the sleeve presses against the first sealing ring against the male connector. The connecting sleeve not only provides rain protection, preventing rainwater from entering and causing charging accidents, but also stabilizes the female connector on the male connector, improving the stability of the connection. After charging is complete, slide the connecting sleeve away from the vehicle body to separate the permanent magnet from the rubber annular magnet, then detach it from both the female and male connectors.
