[0034] According to a first aspect of the present invention, there is provided an integrated connector having a filter magnetic ring, such as Figures 1 to 5As shown, the integrated connector with a filter magnetic ring is used for an inverter of a new energy vehicle. The integrated connector with a filter magnetic ring has a small overall volume, which reduces the occupied space. The integrated connector with a filter magnetic ring includes a socket part 1 and a plug part 2.

[0035] In the following description, reference will be made to Figures 1 to 5 The detailed structures of the socket part 1 and the plug part 2 of the integrated connector with the filter magnetic ring are described in detail.

[0036] like Figures 1 to 5 As shown, in an embodiment, the inverter may include a housing 3, which may be understood as a housing of the inverter. The socket portion 1 and the plug portion 2 may be docked with each other to achieve current transmission. Specifically, the socket portion 1 includes a socket housing 101, a filter magnetic ring 102 and a connecting column 103, and the socket housing 101 is used to accommodate the filter magnetic ring 102 and the connecting column 103. The filter magnetic ring 102 may be formed into a circular ring structure, which is sleeved on the outside of the connecting column 103 and arranged inside the socket housing 101. The material of the filter magnetic ring 102 may be nanocrystals, which may be materials in the prior art and may filter out most of the ultra-high frequency signals between 300MHz and 3GHz. The filter magnetic ring 102 may also be a component in the prior art. In the present application, the filter magnetic ring 102 and the socket portion 1 are an integral structural member to achieve the role of integration. This design method can not only achieve reliable transmission of electric energy, but also concentrate and filter the magnetic field through the filter magnetic ring 102, thereby improving the electromagnetic compatibility (EMC) performance of the entire system. Compared with the separately designed solution in the prior art, this has higher EMC performance and helps to improve the stability and reliability of the system.

[0037] The connecting column 103 may be formed as a cylindrical structure, and the connecting column 103 may be, for example, a copper column used for current transmission in a connector. Figure 4 As shown, the end of the socket housing 101 facing the plug part 2 is provided with an annular groove 104 and a cylindrical groove 105, and the shape structure of the annular groove 104 and the shape structure of the cylindrical groove 105 correspond to the filter magnetic ring 102 and the connecting column 103 respectively.

The socket housing 101 is also provided with a first connection position 106, and the socket part 1 is arranged on the box body 3 through the first connection position 106. The first connection position 106 can be arranged on the socket housing 101, and a connecting through hole is opened. The socket part 1 can be fixedly connected to the box body 3 by using a connecting member 4. The connecting member 4 can be, for example, a connecting screw. In addition, it should be noted that since the socket part 1 is usually arranged inside the box body 3, the socket part 1 is usually fixedly connected to the box body 3. When the connector is plugged in or unplugged, the plug part 2 is plugged in or unplugged to achieve disconnection or connection.

[0038] like Figure 1 , Figure 2 and Figure 5 As shown, in the embodiment, the plug part 2 may include a plug housing 201 and a plug pin 202, the plug pin 202 is arranged inside the plug housing 201, the plug part 2 is docked with the connection column 103 of the socket part 1 through the plug pin 202, the plug housing 201 is provided with a second connection position 203, when the plug part 2 is docked with the socket part 1, the plug part 2 is arranged on the box 3 through the second connection position 203. The second connection position 203 may be arranged on the plug housing 201, and a connection through hole is provided, and the plug part 2 may use a connector 4 to fix the second connection position 203 with the box 3. In this way, due to the provision of the first connection position 106 and the second connection position 203, the socket part 1 and the plug part 2 can be fixed to the box 3 after being connected, so that the high-voltage interlocking harness can be saved inside the connector assembly, the wiring and harness fixing space are saved, and the separation of the socket part 1 and the plug part 2 caused by external force does not need to be considered, thereby reducing the overall volume of the connector and meeting the trend of miniaturization.

[0039] In summary, the integrated connector with a filter magnetic ring integrates the filter magnetic ring 102 inside the socket part 1 through the cooperation of the socket part 1 and the plug part 2, reduces the number of parts of the inverter, does not need to reserve installation gaps and electrical gaps, reduces the difficulty and cost of assembly, improves the EMC performance of the connector, and saves internal space; in addition, after the socket part 1 and the plug part 2 are connected, they are respectively installed on the box body 3 through the first connection position 106 and the second connection position 203, thereby ensuring the connection strength, avoiding the separation of the socket part 1 and the plug part 2 due to external force, and also eliminating the high-voltage interlocking harness inside the connector assembly in the original structure, reducing the volume of the connector and the inverter, and meeting the design requirements of miniaturization.

In order to make the filter magnetic ring 102 firmly bonded and fully infiltrated by the potting glue, a convex block 107 is arranged between the filter magnetic ring 102 and the bottom of the annular groove 104, so that the potting glue can enter between the filter magnetic ring 102 and the bottom of the annular groove 104 to ensure the bonding strength. When the filter magnetic ring 102 is arranged in the annular groove 104, a gap of 0.5 mm is left between the outer wall of the filter magnetic ring 102 and the outer wall of the annular groove 104 to facilitate the entry of the potting glue.
