Description

Technical Field

[0001] The utility model relates to the technical field of hybrid boxes, in particular to a connection structure of a magnetic isolation high-voltage line seat and a hybrid box. Background Art

[0002] The existing high-voltage line terminal block is generally a plastic-coated copper busbar structure, which is installed between the motor housing and the electronic control housing. A flange plate is provided in the middle of the copper busbar of the terminal block, and corresponding copper busbars are respectively installed on two opposite sides in the thickness direction of the flange plate. The copper busbars are used to connect the corresponding structures and transmit current. A motor copper busbar is provided on one side of the copper busbar of the terminal block and is used to connect the motor, and a controller copper busbar is provided on the other side and is used to connect the controller. Since the flange plate for installing the copper busbar is located between the two housings and is not wrapped by the magnetic isolation cavity, the existing structure will leak magnetic flux from the position of the flange plate, resulting in poor magnetic isolation effect of the high-voltage line terminal block as a whole after connection. Utility Model Content

[0003] Based on this, a connection structure of a magnetically isolated high-voltage line seat and a hybrid box are provided to improve the problem of magnetic leakage from the flange plate of the high-voltage line connection seat in the prior art.

[0004] On the one hand, the utility model provides a connection structure of a magnetically isolated high-voltage line seat, including a flange plate located in the middle, the flange plate having two oppositely arranged connection sides, the two connection sides being respectively used to abut against a motor housing and a controller housing and form two closed cavity structures, the motor housing and the controller housing being both metal housings; at least one of the two connection sides is covered with a magnetically isolated plate.

[0005] On the basis of the above technical solution, the present invention can also be improved as follows.

[0006] In one of the embodiments, a motor copper busbar and an electric control copper busbar are respectively installed in the middle of the two connection sides, and a plurality of connection holes are opened near the edges of the connection sides.

[0007] In one embodiment, a plurality of connecting ears are extended from the flange plate in a direction perpendicular to the thickness of the flange plate, and the connecting holes are formed in the connecting ears.

[0008] In one embodiment, the connection holes surround the outer circumference of the motor copper busbar and the electric control copper busbar.

[0009] In one embodiment, a gap is opened in the middle of each magnetic isolation plate and a motor copper busbar or an electric control copper busbar is extended therefrom. The motor copper busbar is used to connect the motor and extend into the motor housing, and the electric control copper busbar is used to connect the controller and extend into the controller housing.

[0010] In one of the embodiments, there are two magnetic isolation plates, which are divided into an upper magnetic isolation plate and a lower magnetic isolation plate. The upper magnetic isolation plate is on the same side as the electric control copper busbar, and the lower magnetic isolation plate is on the same side as the motor copper busbar. The magnetic isolation plates are fitted with the corresponding connection sides.

[0011] In one embodiment, the upper magnetic isolation plate and the lower magnetic isolation plate are arranged on both sides of the flange plate in the thickness direction. Both the upper magnetic isolation plate and the lower magnetic isolation plate are provided with bending structures at the outer contour of the flange plate and along the thickness direction of the flange plate, and the two bending structures are arranged overlappingly.

[0012] In one of the embodiments, the upper magnetic isolation plate includes an annular connecting rib protruding away from the flange plate, the connecting rib surrounds the outer periphery of the electric control copper busbar and is used to abut against the controller housing.

[0013] In one embodiment, the magnetic isolation plate is a thin plate made of metal.

[0015] The beneficial effects of the present invention are as follows: by covering a magnetic isolation plate on at least one side of the flange plate, two closed cavities are formed after the flange plate is abutted with the motor housing and the controller housing. While the metal structure of the motor housing and the controller housing has a magnetic isolation effect on the closed cavity, the connecting side with the magnetic isolation plate can also be used to isolate the motor housing and / or the controller housing from the abutting position with the flange plate, thereby improving the isolation effect of the closed cavity on the side where the magnetic isolation plate is located, and avoiding the large amount of magnetic leakage phenomenon at the flange plate in the prior art due to the flange plate being a plastic plate that cannot isolate magnetic fields. In summary, the present application reduces the magnetic leakage at the flange plate position, thereby improving the magnetic isolation effect at the high-voltage line seat connection.
