Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of Chinese Patent Application No. CN202410533473.1 filed on April 29, 2024, and Chinese Patent Application No. CN202410980589.X filed on July 19, 2024, with the State Intellectual Property Administration of China, the entire disclosures of which are incorporated herein by reference.

[0002] The present invention relates to power transfer components, electrical connection assemblies comprising power transfer components, and electrical connection products comprising electrical connection assemblies. [Background technology]

[0003] In the prior art, large-section conventional wires are commonly used to transmit current between the battery packs of new energy electric vehicles and the power source. Due to the high current of up to 1000 A when charging the battery pack, the temperature rise of the conventional wires is large, making it difficult to meet the requirements and even causing fires. In addition, the conventional wires use copper cores, and the cost of large-section copper cores is very high.

[0004] In the prior art, aluminum busbar wires are commonly used instead of traditional copper core wires to reduce the temperature rise and cost of the wires. However, the aluminum busbar wires in the prior art only include a single aluminum busbar. When multiple different conductive components need to be electrically connected separately, multiple aluminum busbar wires need to be provided, which can make the electrical connection inconvenient and result in a large volume and high cost of the electrical connection product.

The two cooling channels 10 are adjacent to a first metal bar 11 and a second metal bar 12, respectively, and therefore, the first metal bar 11 and the second metal bar 12 can be cooled by a cooling fluid flowing through the two cooling channels 10.

[0150] However, the present invention is not limited to the illustrated embodiment. For example, in another exemplary embodiment of the present invention, a single cooling channel 10 may be formed in the insulator 13, so that the first metal bar 11 and the second metal bar 12 can be cooled simultaneously by a cooling fluid flowing through the single cooling channel 10.

[0151] As shown in Figures 34 to 41, in the illustrated embodiment, the insulator 13 has a partition 13b that separates the cooling channel 10 from the first metal bar 11 and the second metal bar 12, so that the cooling fluid flowing through the cooling channel 10 cannot physically come into contact with the first metal bar 11 and the second metal bar 12.

[0152] As shown in Figures 34 to 41, in the illustrated embodiment, the insulator 13 is an injection molded part formed directly on the first metal bar 11 and the second metal bar 12 by an embedded injection molding process, and therefore the first metal bar 11, the second metal bar 12, and the insulator 13 are integrated into one piece.

[0153] 34-41 , in the illustrated embodiment, the electrical connection product further includes an insulating cap assembly 200.

[0156] 34 to 41, in the illustrated embodiment, the first metal bar 11 and the second metal bar 12 each have a top surface and a bottom surface that are opposite in their thickness direction, and two side surfaces that are opposite in their width direction. The first metal bar 11 and the second metal bar 12 are arranged side by side and spaced apart on opposite sides from each other in the width direction, and the cooling channel 10 is arranged between the side of the first metal bar 11 and the side of the second metal bar 12.

[0157] As shown in Figures 34 to 41, in the illustrated embodiment, two cooling channels 10 are formed in an insulator 13, and the insulator 13 has an intermediate partition wall 13a separating the two cooling channels 10 and a partition wall 13b separating the cooling channel 10 from the first metal bar 11 and the second metal bar 12.

[0158] As shown in Figures 34 to 41, in the illustrated embodiment, the insulating cap 2 has two pipe joints 20 that respectively communicate with the end openings of the two cooling channels 10 of the power transmission component 1, so that the cooling fluid can flow into or out of the two cooling channels 10 through the two pipe joints 20.

[0159] 34 to 41, in the illustrated embodiment, the insulating cap 2 also has a partition rib 22a formed on the inner surface of the end wall 220, and the sealing component 3 also has an isolation rib 3a disposed on and connected to the annular body 30. The isolation rib 3a of the sealing component 3 is compressed between the partition rib 22a of the insulating cap 2 and the end face of the intermediate partition wall 13a of the insulator 13 to isolate the end openings of the two fluid channels 10 from each other and isolate the two pipe joints 20 from each other.

[0160] 34-41, in the illustrated embodiment, the insulating cap 2 is inserted into the housing 5, and the pipe joint 20 of the insulating cap 2 is exposed from the housing 5 for connection to the connecting pipe of the cooling circuit. The insulating cap assembly 200 also includes an external sealing ring 4 attached to the peripheral wall 210 of the insulating cap 2. The external sealing ring 4 is radially compressed between the insulating cap 2 and the housing 5 to provide a seal between the two.

[0161] 34 to 41, in the illustrated embodiment, the power transmission component 1 has a cooling channel 10 disposed between a first metal bar 11 and a second metal bar 12, and therefore the first metal bar 11 and the second metal bar 12 can be sufficiently cooled by the cooling fluid flowing through the cooling channel 10. The cooling channel 10 of the present invention has a large cooling area and high cooling efficiency, which can effectively reduce the temperature rise of the power transmission component without increasing the cross-sectional area of ​​the metal bars.

30. Two cooling channels (10) are formed in the insulator (13), and the insulator (13) has a middle partition wall (13a) separating the two cooling channels (10) and a partition wall (13b) separating the cooling channel (10) from the first metal bar (11) and the second metal bar (12).

30. The electrical connection product of claim 29.

31. the insulating cap (2) has two pipe joints (20), which are respectively in communication with the end openings of the two cooling channels (10) of the power transmission component (1), so that the cooling fluid can flow into or out of the two cooling channels (10) through the two pipe joints (20); 31. The electrical connection product of claim 30.

32. The insulating cap (2) also has a partition rib (22a) formed on the inner surface of the end wall (220), and the sealing component (3) also has a separating rib (3a) disposed on the annular body (30) and connected to the annular body (30); the separating rib (3a) of the sealing component (3) is compressed between the partition rib (22a) of the insulating cap (2) and the end face of the intermediate partition wall (13a) of the insulator (13) to separate the end openings of the two fluid channels (10) from each other and to separate the two pipe joints (20) from each other; 32. The electrical connection product of claim 31.

33. The insulating cap (2) is inserted into the housing (5), and the pipe joint (20) of the insulating cap (2) is exposed from the housing (5) for connection to a connecting pipe of the cooling circuit; The insulating cap assembly (200) comprises: An external sealing ring (4) attached to the insulating cap (2) Furthermore, The outer sealing ring (4) is radially compressed between the insulating cap (2) and the housing (5) to provide a seal between the insulating cap (2) and the housing (5).

27. The electrical connection product of claim 26.
