By providing at least a plurality of first through holes 22, a plurality of first copper bars 10 can be arranged on the same base 20 to increase the number of connection lines of the high-voltage connector. The partitions 21 are provided to separate the first copper bars 10, thereby avoiding circuit confusion. The partitions 21 provided can further increase the contact height between the first copper bar 10 and the outside world, that is, the partitions 21 are used to block the contact between external objects and the first copper bar 10 to reduce the occurrence of false touches.

[0029] In this embodiment, the connection between the first copper busbar 10 and the first through hole 22 is sealed by glue potting, so that different installation spaces are isolated and / or sealed by different media.

[0030] In this embodiment, the side of the base 20 has an extension platform 30, the extension platform 30 is located below the first through hole 22, the surface of the extension platform 30 is provided with a first fastener 31, and one end of the first copper bar 10 has a fourth through hole 13 that can be matched with the base 20, and the fourth through hole 13 and the first fastener 31 can be arranged correspondingly. The setting of the extension platform 30 is used to enhance the structural strength of the bottom of the base 20 and realize the fixed connection with the first copper bar 10 through the extension platform 30. In addition, the extension platform 30 is provided to make the first copper bar 10 form a bent shape. In this way, after forming a connection relationship with the extension platform 30, the bent shape of the first copper bar 10 can reduce the probability of it loosening or separating relative to the base 20.

[0031] In this embodiment, one end of the first copper busbar 10 can be connected and fixed to the first fastener 31, and the first fastener 31 is a nut. The fourth through hole 13 of the first copper busbar 10 can be aligned with the nut and the first copper busbar 10 and the nut of the extension platform 30 can be fastened and assembled under the action of the bolt.

[0032] In this embodiment, the base 20 has a limit sleeve pin 23 with a through hole in the middle. The limit sleeve pin 23 is a circular ring structure. The base 20 has a hole body connected to the through hole in the middle of the limit sleeve pin 23. The limit sleeve pin 23 is used to determine the accuracy of installation. The limit sleeve pin 23 can be used to pre-position and install the base 20 at a preset position.

[0033] In this embodiment, the limiting sleeve pin 23 is disposed on at least one side surface of the base 20 .

[0034] In this embodiment, a sealing ring groove is provided on the base 20, and a sealing ring 24 is installed in the sealing ring groove. At least two sealing rings 24 are provided, and the sealing rings 24 are arranged on the upper and lower sides of the base 20 to meet the sealing requirements. In this embodiment, the requirements are specifically met that oil is stored on the gearbox side of the side of the device in the installed state, and there is no oil in the controller installation cavity.

[0035] Embodiment 2:

[0036] See attached Figure 6-Figure 8 As shown, this embodiment provides a further solution based on the embodiment 1, the first copper bar 10 is provided with a second through hole 11, the first copper bar 10 is provided with a second copper bar 40 on the side, the second copper bar 40 has a first plate body 41 that can pass through the second through hole 11, the first plate body 41 is provided with a fifth through hole 42, and the first copper bar 10 is provided with a third through hole 12 corresponding to the fifth through hole 42. The second copper bar 40 provided can play an auxiliary strengthening role for the first copper bar 10. After the first copper bar 10 is bent and spatially arranged, the layout strength of the first copper bar 10 can be strengthened by installing the second copper bar 40 on one side of the first copper bar 10 to prevent it from being easily over-deformed. In addition, the second copper bar 40 can reduce the probability of the first copper bar 10 deforming in the two-way direction, that is, the preset posture of the first copper bar 10 is maintained.

[0037] The first plate body 41 is the bent portion of the end of the second copper bar 40. The first plate body 41 and the end of the second copper bar 40 form a hook shape, so that after the first plate body 41 passes through the second through hole 11, the second copper bar 40 has a certain position limiting effect relative to the first copper bar 10. Based on this, the first plate body 41 and the first copper bar 10 are fastened by bolts or screws passing through the fifth through hole 42 and the third cylinder 12 in sequence, so that the second copper bar 40 and the first copper bar 10 are connected. For the characteristics of the first copper bar 10 being a soft copper bar or being able to be bent, there may be a situation of partial breakage. When the first copper bar 10 is partially broken, it is more troublesome to replace it. By setting the first plate body 41 of the second copper bar 40 to pass through the second through hole 11 to form a connection with the first copper bar 10, it can be used to replace the broken part of the first copper bar 10, thereby improving the flexibility of parts replacement and reducing maintenance and repair costs.
