They are one of the key components for power transmission in new energy vehicles. Their housings are made of plastic, making them small and lightweight, which helps reduce the overall weight of the vehicle and also facilitates installation within the limited space inside the vehicle.

[0003] Traditional connectors for new energy vehicles have a relatively simple structure. The male and female connectors may fall off due to collisions, causing the male and female pins to separate. Their stability is generally poor. Therefore, an improvement has been made to a connector for new energy vehicles. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a connector for new energy vehicles, which overcomes the deficiencies of existing technologies and aims to solve the problem that traditional connectors for new energy vehicles have a relatively simple structure, and the male and female connectors may fall off due to collisions, resulting in the male and female pins separating and the stability being relatively poor.

[0005] To achieve the above objectives, this application provides the following technical solution: a connector for new energy vehicles, comprising a male connector and a female connector. The male connector has a male pin assembly at its insertion end, and the female connector has a female pin assembly at its receiving end. The female pin assembly has a connection hole for inserting the male pin assembly at one end near the male pin assembly.

The elastic deformation of the elastic clips provides appropriate clamping force, ensuring good electrical contact between the male pin assembly and the female pin assembly. By sliding the elastic pin into the inside of the buckle and engaging it together, an elastic locking structure is formed, which can fix the protective cover and the connector together, thereby effectively preventing the male end connector and the female end connector from separating due to external forces such as collisions. In other words, this connector greatly improves the stability of the connection compared with traditional connectors.

[0007] As a preferred technical solution of this application, the number of female needle components and male needle components are the same and correspond one-to-one, and the male needle component is provided with a chamfer at the end near the female needle component.

[0009] As a preferred technical solution of this application, the protective cover has an outward convex structure design, and the protective cover covers the male pin assembly inside it.

[0010] By adopting the above technical solution, the protective cover has an outward convex structure and covers the male pin assembly inside, which can provide physical protection for the male pin assembly and prevent the male pin assembly from being deformed by external collisions, squeezing, etc.

[0011] As a preferred technical solution of this application, a guide rod is fixedly connected to the upper surface of the protective cover, and a guide frame for the guide rod to pass through is fixedly connected to the upper surface of the connecting seat, wherein the outer diameter of the guide rod is adapted to the inner diameter of the guide frame.

[0012] By adopting the above technical solution, the guide rod on the protective cover is adapted to the guide frame on the connector. During the connector installation process, the guide rod can be inserted into the guide frame, providing precise positioning for the mating of the male and female connectors, ensuring that the male pin assembly can be smoothly inserted into the connection hole of the female pin assembly.

[0013] As a preferred technical solution of this application, the number of elastic pins and buckles is two, and the two elastic pins and buckles are symmetrically distributed on both sides of the guide rod.

[0014] By adopting the above technical solution and setting two elastic pins and buckles symmetrically distributed on both sides of the guide rod, the reliability of the connection is further enhanced, so that the connector can have better resistance when subjected to external forces in different directions.

[0015] As a preferred technical solution of this application, a sealing groove is provided on the side of the protective cover near the connecting seat, and a sealing strip is fixedly connected to the side of the connecting seat near the protective cover, and the sealing strip is slidably inserted into the interior of the sealing groove.

Copper alloy has good conductivity and wear resistance, which can ensure efficient current transmission and long-term use of the connector. The male connector, female connector, protective cover and connector base are all plastic components, which have the advantages of light weight and good insulation performance, which can reduce the overall weight of the connector, and at the same time effectively prevent safety problems such as leakage.

[0019] In summary, the beneficial effects of this application are as follows: 1. In this application, by providing elastic clips and expansion joints on the outer wall of the female pin assembly, the female pin assembly can adapt to the insertion of the male pin assembly to a certain extent. The elastic deformation of the elastic clips provides appropriate clamping force, ensuring good electrical contact between the male pin assembly and the female pin assembly. By sliding the elastic pin into the inside of the buckle and engaging it together, an elastic locking structure is formed, which can fix the protective cover and the connector together, thereby effectively preventing the male end connector and the female end connector from separating due to external forces such as collisions. That is, compared with traditional connectors, this connector greatly improves the stability of the connection.

[0020] 2. The guide rod on the protective cover is compatible with the guide frame on the connector. During connector installation, the guide rod can be inserted into the guide frame, providing precise positioning for the mating of the male and female connectors. This ensures that the male pin assembly can be smoothly inserted into the connection hole of the female pin assembly. The sealing strip slides into the sealing groove to ensure the sealing between the protective cover and the connector. This effectively prevents dust, moisture, etc., from entering the connector and avoids problems such as poor contact caused by external impurities. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this application easy to understand, the following describes this application in conjunction with specific implementation methods.

[0024] like Figure 1 - Figure 4 As shown, this embodiment provides a connector for new energy vehicles, including a male connector 1 and a female connector 2. The male connector 1 has a male pin assembly 3 at its insertion end, and the female connector 2 has a female pin assembly 4 at its receiving end. The female pin assembly 4 has a connection hole 401 near the male pin assembly 3 for insertion of the male pin assembly 3. The outer wall of the female pin assembly 4 is composed of several elastic clips 402, and expansion joints 403 are provided between the elastic clips 402. A protective cover 5 is fixedly connected to the outer wall of the male connector 1, and an elastic pin 7 is fixedly connected to the side wall of the protective cover 5. A connecting seat 6 is fixedly connected to the outer wall of the female connector 2, and a buckle 8 is fixedly connected to the side wall of the connecting seat 6. The male pin 7 slides into the inside of the buckle 8. During use, the female pin assembly 4 is able to adapt to the insertion of the male pin assembly 3 to a certain extent by setting the elastic clip 402 and the expansion joint 403 on the outer wall of the female pin assembly 4. The elastic clip 402 provides appropriate clamping force through elastic deformation, ensuring good electrical contact between the male pin assembly 3 and the female pin assembly 4. By sliding the elastic pin 7 into the inside of the buckle 8 and locking them together, an elastic locking structure is formed, which can fix the protective cover 5 and the connector 6 together, thereby effectively preventing the male end connector 1 and the female end connector 2 from separating due to external forces such as collision. That is, compared with traditional connectors, this connector greatly improves the stability of the connection.

[0025] In this embodiment, as Figure 2 and 4 As shown, the number of female pin assemblies 4 and male pin assemblies 3 are the same and correspond one-to-one. The male pin assembly 3 is provided with a chamfer 301 at the end near the female pin assembly 4. In use, the number of female pin assemblies 4 and male pin assemblies 3 are the same and correspond one-to-one, which ensures the accuracy and stability of the current transmission path. The chamfer 301 at the end of the male pin assembly 3 near the female pin assembly 4 makes it easy for the male pin assembly 3 to be smoothly inserted into the connection hole 401 of the female pin assembly 4, which can reduce the resistance and wear during insertion, and improve the convenience of insertion and removal and the service life.

[0026] In this embodiment, as Figure 2 and3 As shown, the protective cover 5 has an outward convex structure design, and the protective cover 5 covers the male needle assembly 3 inside. When in use, the protective cover 5 has an outward convex structure and covers the male needle assembly 3 inside, which can provide physical protection for the male needle assembly 3 and prevent the male needle assembly 3 from being deformed by external collisions, squeezing, etc.

[0027] In this embodiment, as Figure 1 As shown, a guide rod 11 is fixedly connected to the upper surface of the protective cover 5, and a guide frame 12 for the guide rod 11 to pass through is fixedly connected to the upper surface of the connector 6. The outer diameter of the guide rod 11 is matched with the inner diameter of the guide frame 12. In use, the guide rod 11 on the protective cover 5 is matched with the guide frame 12 on the connector 6. During the connector installation process, the guide rod 11 can be inserted into the guide frame 12, providing precise positioning for the mating of the male connector 1 and the female connector 2, ensuring that the male pin assembly 3 can be smoothly inserted into the connection hole 401 of the female pin assembly 4.

[0028] In this embodiment, as Figure 1 and 3 As shown, there are two elastic pins 7 and two snap fasteners 8, and the two elastic pins 7 and two snap fasteners 8 are symmetrically distributed on both sides of the guide rod 11. In use, the two elastic pins 7 and two snap fasteners 8 symmetrically distributed on both sides of the guide rod 11 further enhance the reliability of the connection, so that the connector can have better resistance when subjected to external forces in different directions.

[0029] In this embodiment, as Figure 2 and 3 As shown, a sealing groove 9 is provided on the side of the protective cover 5 near the connector 6. A sealing strip 10 is fixedly connected to the side of the connector 6 near the protective cover 5. The sealing strip 10 is slidably inserted into the interior of the sealing groove 9. During use, it ensures the sealing of the connection between the protective cover 5 and the connector 6, effectively preventing dust, moisture and other substances from entering the connector and avoiding problems such as poor contact caused by external impurities.

[0030] In this embodiment, as Figure 1 and 3 As shown, both the male pin assembly 3 and the female pin assembly 4 are made of copper alloy. The male connector 1, female connector 2, protective cover 5, and connector 6 are all plastic components. In use, the male pin assembly 3 and the female pin assembly 4 are made of copper alloy, which has good conductivity and wear resistance, ensuring efficient current transmission and long-term use of the connector. The male connector 1, female connector 2, protective cover 5, and connector 6 are all plastic components, which have advantages such as light weight and good insulation performance, reducing the overall weight of the connector and effectively preventing safety issues such as leakage.

[0031] The working principle of this application is as follows: When using a connector for new energy vehicles according to this application, the operator aligns the insertion end of the male connector 1 with the receiving end of the female connector 2. At this time, the guide rod 11 on the protective cover 5 first engages with the guide frame 12 on the connector 6. Contact the guide rod 11 and insert it into the guide frame 12 to ensure that the connection holes 401 of the male needle assembly 3 and the female needle assembly 4 are precisely aligned. Push the male end connector 1 towards the female end connector 2. Under the guidance of the guide angle 301, the male needle assembly 3 is smoothly inserted into the connection hole 401 of the female needle assembly 4. Since the outer wall of the female needle assembly 4 is composed of several elastic clips 402 with deformation seams 403, the male needle assembly 3 will squeeze the elastic clips 402 when inserted, causing them to deform slightly outward. The elastic force of the elastic clips 402 generates a clamping force to tightly wrap the male needle assembly 3. The elastic pin 7 on the side wall of the protective cover 5 slides into the buckle 8 on the connector 6 to form an elastic locking structure. After the docking is completed, the sealing groove 9 on the protective cover 5 and the sealing strip 10 on the connector 6 are tightly fitted to achieve physical isolation, and the docking installation of the connector is completed.
