Description

Technical Field

[0001] This utility model relates to the field of conductive component structures, and in particular to a thinned conductive ring and its connection structure with a flat conductor. Background Technology

[0002] In recent years, the automotive industry has developed rapidly along with the improvement of the economy and people's living standards. Among them, automotive busbars are a type of conductor used in automobiles as a secondary conductive component. Common automotive busbars include copper busbars and aluminum busbars.

[0003] Chinese patent CN116722374A describes a flat aluminum busbar structure, which involves a conductive ring at the end of the aluminum busbar body, connecting it to a wire lug. However, when tightening the connection between the wire lug and the conductive ring, excessive torque can cause deformation of the conductive ring, potentially damaging the connection between the conductive ring and the aluminum busbar body. Since the conductive ring is thicker than the aluminum busbar, longer screws are required. Furthermore, the screw and nut protrude from both ends of the conductive ring, increasing the overall height of the connection and requiring more space for installation, making assembly difficult in compact areas. Utility Model Content

[0004] In view of the above-mentioned defects in the prior art, the main purpose of this utility model is to overcome the shortcomings of the prior art and disclose a thinned conductive ring, including a conductive ring body, the conductive ring body having a disc-shaped structure, and a through connecting hole in the middle of the conductive ring body.

[0005] Furthermore, a connecting ring is protruding from the upper surface of the conductive ring body, and the connecting ring and the conductive ring body form a receiving cavity.

[0006] Furthermore, the conductive ring body is one of a circle, an oblong shape, a square shape, or a polygon.

[0009] Furthermore, the conductive ring is made of pure copper, copper alloy, or aluminum alloy.

[0010] A connection structure between a thinned conductive ring and a flat conductor, using any of the aforementioned thinned conductive rings, wherein the flat conductor is provided with mounting holes, and the conductive ring body is fixed to the upper or lower surface of the flat conductor.

[0011] Furthermore, the mounting hole mates with the connecting ring, and the mounting hole, the connecting ring, and the conductive ring body are fixed by high-energy beam welding.

[0012] Furthermore, the flat conductor is a single-layer structure or a multi-layer structure, and the number of layers in the multi-layer flat conductor is not less than 3 layers and not more than 30 layers.

[0013] Furthermore, a mounting groove is recessed on the flat conductor, the mounting groove accommodates the conductive ring body, and the conductive ring body is fixed to the mounting groove by high-energy beam welding.

[0014] The beneficial effects achieved by this utility model are:

[0015] This invention incorporates a connecting ring, which, together with the conductive ring body, forms a cavity to conceal the nut after installation, thereby reducing the overall installation height and resulting in a compact assembly structure. The flat conductor and conductive ring are welded using a high-energy beam, ensuring sufficient contact area between them while addressing the issue of excessive conductive ring thickness.

Figures 1-3As shown, in the embodiment described above, a conductive ring is used. A mounting hole is provided on the flat conductor 3, and the conductive ring body 1 is fixed to the upper and lower surfaces of the flat conductor 3. In use, the wire lug passes through the connection hole 11 and is locked to the conductive ring body 1 by a nut, thereby achieving an electrical connection with the flat conductor 3.

During assembly, the connecting ring 2 is placed in the mounting hole, and the surface of the conductive ring body 1 is in contact with the lower surface of the conductive busbar.

The high-energy beam welding uses a composite welding method of butt welding and through welding, and the resulting weld connects the conductive ring body 1, the connecting ring 2, and the conductive busbar. When connecting with a wire lug, the nut can be partially or completely hidden in the receiving cavity to reduce the overall installation thickness.

During assembly, the connecting ring 2 is placed in the mounting hole, and the surface of the conductive ring body 1 is in contact with the lower surface of the conductive busbar. The conductive ring and the conductive busbar are connected by high-energy beam welding.

The conductive ring and the conductive busbar are connected by high-energy beam welding. The high-energy beam welding uses a composite welding method of butt welding and through welding, and the resulting weld seam connects the conductive ring body 1, the connecting ring 2, and the conductive busbar; and the multi-layer structure of the conductive busbar is welded together through the weld seam. When connected to the lug, the nut can be partially or completely hidden in the receiving cavity to reduce the overall installation thickness.

During assembly, the connecting ring 2 is placed in the mounting holes, and the mounting groove 32 accommodates the conductive ring body 1.

During assembly, the connecting ring 2 is placed inside the mounting holes, and the surface of the conductive ring body 1 is in contact with the lower surface of the flat conductor 3.
