Preferred embodiments of the present application are described in detail below, however, the present application may have other embodiments in addition to these detailed descriptions.
A bus bar 100 according to an embodiment of the present application is described below with reference to fig. 1 to 6. As shown in fig. 1, a bus bar 100 is applied to a power distribution system, the bus bar 100 including: a metal connector 120; a metal wire 110, at least one end of the metal wire 110 is provided with the metal connector 120, and the metal connector 120 is electrically connected with the metal wire 110, and the metal connector 120 is used for electrically connecting an electric connection part in the power distribution system; wherein the metal connector 120 has a chemical activity smaller than that of the metal wire 110.
Specifically, the end of the metal wire 110 is electrically connected to the electrical connection part in the power distribution system through the metal connector 120, and the end of the metal wire 110 is not directly in contact with the electrical connection part but the metal connector 120 is directly in contact with the electrical connection part, and since the chemical activity of the metal connector 120 is smaller than that of the metal wire 110, the electrochemical reaction between the metal connector 120 and the electrical connection part can be avoided or the electrochemical reaction between the metal connector 120 and the electrical connection part is less than that between the end of the metal wire 110 and the electrical connection part, so that the risk of electrochemical corrosion of the end of the metal wire 110 can be reduced, and the normal use of the metal wire 110 can be ensured.
Based on this, the present application provides a bus bar 100 capable of reducing the risk of electrochemical corrosion. According to the bus bar 100 of the present application, the metal connector 120 having chemical activity smaller than that of the metal wire 110 is disposed at the end of the metal wire 110, and the metal connector 120 is directly electrically connected to the electrical connection portion in the power distribution system, so that electrochemical reaction between the metal connector 120 and the electrical connection portion can be avoided or the electrochemical reaction rate between the end of the metal wire 110 and the electrical connection portion is smaller than that between the end of the metal wire 110 and the electrical connection portion, thereby reducing the risk of electrochemical corrosion at the end of the metal wire 110 and ensuring normal use of the metal wire 110.
In one example, the metal connector 120 may be provided only at one of the ends of the metal wire 110, which is electrically connected to an electrical connection in the power distribution system by the metal connector 120, which is protected by the metal connector 120, reducing the risk of electrochemical corrosion of the end.
In one example, as shown in fig. 2, metal connectors 120 may be disposed at two ends of the metal wire 110, and each end is electrically connected to an electrical connection portion in the power distribution system through the metal connectors 120, where the metal connectors 120 protect the end electrically connected thereto, so as to reduce the risk of electrochemical corrosion of the end.
Illustratively, the metal wire 110 includes a first end and a second end, each of which is provided with one metal connector 120, and the power distribution system includes a first electrical connection portion configured to electrically connect the first electrical connection portion through the metal connector 120 and a second electrical connection portion configured to electrically connect the second electrical connection portion through the metal connector 120. Thus, the first end portion and the second end portion can be protected by the two metal connectors 120, respectively, and the risk of electrochemical corrosion of the first end portion and the second end portion is reduced.
In one example, the first electrical connection may include a charging port of the power distribution system.
In one example, the second electrical connection may include a battery connector of the power distribution system.
Bus bar 100 may provide an electrical connection between a charging port and a battery connector to enable charging of the vehicle.

In one example, as shown in fig. 2, a plurality of bending points may be provided on the metal wire 110. Illustratively, the metal wire 110 may be bent and formed by a 3D bending machine to the metal material so that the metal wire 110 may be bent at a specific angle or radius to match the interior configuration of the vehicle (e.g., the contour of a wheel well or interior side panel within the vehicle).
In one example, the metal wire 110 may also select a suitable placement fixation point based on the routing path within the vehicle, thereby ensuring that the metal wire 110 is not overstressed locally.
In one example, the metal wire 110 may comprise a solid aluminum wire, although the application is not limited thereto and the metal wire 110 may be an aluminum alloy wire, a copper alloy wire, or the like.

Of course, the ends of the metal wire 110 are not limited to being constructed as flat structures, and may be swaged into various geometries to facilitate connection with electrical connections without departing from the spirit of the application. For example, the ends of the metal wire 110 may also be formed in a cylindrical shape, square, rectangular, hexagonal, notched, folded, angled, or any other configuration.

Among them, the inert metal coating may be a nickel coating, a titanium coating, a gold coating, a silver coating, etc., which is not limited. By providing an inert metal coating, the oxidation resistance of the first flattened portion 113 may be further enhanced, reducing the risk of chemical corrosion of the first flattened portion 113.

Illustratively, as shown in fig. 4, the first flat portion 113 of the metal wire 110 is connected with the second flat portion 121 of the metal connection portion by means of ultrasonic welding. After welding, a part of the lower surface of the second flat part 121 may be connected with a part of the upper surface of the first flat part 113, or a part of the upper surface of the second flat part 121 may be connected with a part of the lower surface of the first flat part 113.
Illustratively, as shown in fig. 5, the first flattened portion 113 of the metal wire 110 is joined to the second flattened portion 121 of the metal connection portion by friction stir welding. After welding, the end face of the second flat portion 121 may be connected with the end face of the first flat portion 113.
Illustratively, as shown in fig. 6, the first flattened portion 113 of the metal wire 110 is joined to the second flattened portion 121 of the metal connection by friction welding.
In one example, as shown in fig. 3, the bus bar 100 further includes an insulating layer 130, and the insulating layer 130 covers the surface of the metal wire 110 and exposes an end portion of the metal wire 110. Illustratively, the insulating layer 130 may be coated only on the outer circumferential surface of the wire body 111, and the insulating layer 130 may not be coated for the transition portion 112 and the first flat portion 113; alternatively, the insulating layer 130 may be coated only on the outer circumferential surfaces of the wire main body 111 and the transition portion 112, and the insulating layer 130 may not be coated on the first flat portion 113.
