[0025] In combination Figure 1 As shown in the drawings, the present application provides a copper bar assembly, which comprises a conductive copper bar 1, an insulating shell 2 and a magnetic ring structure 3. The conductive copper bar 1 is arranged through the insulating shell 2, and both ends of the conductive copper bar 1 extend out of the insulating shell 2. The insulating shell 2 is provided with a receiving groove 4 adapted to the magnetic ring structure 3 at the position of the end of the conductive copper bar 1, and the magnetic ring structure 3 is connected with the insulating shell 2 in the receiving groove 4.
[0026] In this embodiment, the conductive copper bar 1 of the copper bar assembly is made of a material with high conductivity (such as pure copper or copper alloy) for the transmission of current in the corresponding power system; the insulating shell 2 of the copper bar assembly is made of an insulating material resistant to high temperature and high voltage (such as polyamide, polycarbonate or epoxy resin, etc.), which not only protects the conductive copper bar 1, but also isolates the non-connected part of the conductive copper bar 1 from the outside world, ensures the corresponding insulation effect, and can be used to realize the connection of the copper bar assembly with other components (i.e. through the insulating shell 2 and other components). The conductive copper bar 1 penetrates the insulating shell 2 and its two ends extend from the inside of the insulating shell 2, which is convenient for connecting the power supply components and the power consumption components in the power system respectively.
[0027] In order to realize the multifunctional integration of the copper bar assembly, the copper bar assembly further comprises a magnetic ring structure 3, which can be used to suppress the high-frequency noise and common-mode interference of the conductive copper bar 1, and improve the electromagnetic compatibility performance; and / or, for detecting the current in the conductive copper bar 1 (such as through the cooperation of the Hall chip 6 to realize current detection). The end (at least one end) of the conductive copper bar 1 on the insulating shell 2 is provided with a accommodating groove 4 which is adapted to the shape, size, etc. of the magnetic ring structure 3, and the magnetic ring structure 3 is connected with the insulating shell 2 in the accommodating groove 4 (which can be realized by adhesive bonding, clamping and other connection methods), that is, the magnetic ring structure 3 is embedded in the insulating shell 2 at the position corresponding to the end of the conductive copper bar 1 through the accommodating groove 4. On the one hand, the design of the accommodating groove 4 increases the contact area of the magnetic ring structure 3 and the insulating shell 2, improves the stability of the connection of the magnetic ring structure 3 and the insulating shell 2, and can ensure that the magnetic ring structure 3 remains stable under the working conditions of vibration, impact, etc.; on the other hand, it ensures that the relative positional relationship between the magnetic ring structure 3 and the conductive copper bar 1 remains stable, thereby ensuring that the magnetic ring structure 3 can effectively play its corresponding role (such as current detection or electromagnetic compatibility function, etc.); on the other hand, the magnetic ring structure 3 does not need to be installed externally, avoiding the problems of complex external cable wiring and additional space occupied by wiring in traditional separate installation, improving the integration of the copper bar assembly, reducing the overall occupied space of the copper bar assembly, and being conducive to the miniaturization design of the copper bar assembly. In addition, when assembling the copper bar assembly, the conductive copper bar 1 with integrated magnetic ring structure 3 can be used directly, without the need for separate positioning and fixing operations of the magnetic ring structure 3 and the copper bar structure, thereby simplifying the assembly process, reducing the assembly difficulty of the multifunctional integrated copper bar assembly, avoiding the error risk caused by multiple assembly operations, and reducing the assembly cost of the multifunctional integrated copper bar assembly.
[0028] In summary, the copper bar assembly significantly improves the functionality and integration of the copper bar assembly by integrally arranging the conductive copper bar 1, the insulating shell 2 and the magnetic ring structure 3. Moreover, by arranging the accommodating groove 4 for accommodating the magnetic ring structure 3 at the position where the end of the conductive copper bar 1 is located on the insulating shell 2, the magnetic ring structure 3 is connected with the insulating shell 2 in the accommodating groove 4, which increases the connection stability between the magnetic ring structure 3 and the insulating shell 2, so that the magnetic ring structure 3 can maintain stable position under working conditions such as vibration and impact, ensuring the effective play of its function; and avoids the wiring complexity and space waste problems caused by traditional separate installation, reduces the overall occupied space of the multifunctional integrated copper bar assembly, facilitates the miniaturization of the copper bar assembly, at the same time simplifies the assembly process when the copper bar assembly is applied to the corresponding power system, reduces the operation difficulty and error risk when the copper bar assembly is assembled in the corresponding power system, and can meet the corresponding requirements of new energy vehicles for miniaturization, integration and high efficiency of corresponding components.

[0042] Optionally, as shown in Figure 2 、 Figure 3 , the magnetic ring structure 3 further comprises a second magnetic ring 32 for electromagnetic compatibility, and the accommodating groove 4 comprises a second accommodating groove 42; the conductive copper bar 1 has a first end and a second end, and the insulating shell 2 further comprises a second shell 24 arranged around the shell body 21, the second shell 24 and the shell body 21 enclose the second accommodating groove 42 at the second end of the conductive copper bar 1 to form a second accommodating groove 42 with the opening facing the second end of the conductive copper bar 1, and the second accommodating groove 42 is used to arrange the second magnetic ring 32; the second magnetic ring 32 is sleeved on the shell body 21 in the second accommodating groove 42.
[0043] In the embodiment, the two ends of the conductive copper bar 1 extending out of the shell body 21 are respectively marked as a first end and a second end, and the insulating shell 2 further comprises a second shell 24 arranged around the shell body 21. The second shell 24 is integrally formed with the shell body 21, and the second shell 24 and the shell body 21 enclose a second accommodating groove 42 at the second end of the conductive copper bar 1, for arranging the second magnetic ring 32, thereby improving the integration and functionality of the conductive copper bar 1 and improving the installation stability of the second magnetic ring 32 on the insulating shell 2.

The second magnetic ring 32 is used to effectively suppress the high-frequency electromagnetic interference (EMI) generated by the conductive copper bar 1 during current transmission, so as to enhance the electromagnetic compatibility (EMC) of the copper bar assembly. Specifically, when the conductive copper bar 1 is electrified, the rapidly changing current flowing through the copper bar may cause high-frequency electromagnetic radiation, which in turn may interfere with surrounding electronic devices. The second magnetic ring 32, by virtue of its high magnetic permeability, forms a closed magnetic circuit that can absorb and attenuate the energy of high-frequency interference signals, thereby effectively reducing the electromagnetic interference of the conductive copper bar 1 on the external environment. In addition, the second magnetic ring 32 is isolated from the conductive copper bar 1 by the shell body 21, thereby achieving electrical insulation between the conductive copper bar 1 and the second magnetic ring 32 and ensuring the stability and reliability of the long-term operation of the second magnetic ring 32.

[0047] Optionally, after the second magnetic ring 32 is arranged in the second accommodating groove 42, a point gluing process can be used to connect the second magnetic ring 32 and the insulating shell 2, thereby improving the stability of the connection between the second magnetic ring 32 and the insulating shell 2 in the second accommodating groove 42.

[0049] In the embodiment, the copper bar assembly includes a cover plate 7 matched with the opening of the second accommodating groove 42, and the cover plate 7 is used to close the opening of the second accommodating groove 42, so that the cover plate 7 can be combined with the shell body 21 and the second shell 24 to form a relatively closed second accommodating groove 42 for arranging the second magnetic ring 32, further protect the second magnetic ring 32 arranged in the accommodating groove 4 (such as protecting the second magnetic ring 32 from the external environment such as dust, moisture, etc., and reducing or preventing the influence of external impact or vibration on the second magnetic ring 32) and improve the stability of the overall structure of the copper bar assembly.
[0050] In order to ensure that the cover plate 7 is smoothly assembled to the insulating shell 2 at the opening of the second accommodating groove 42, the cover plate 7 is further provided with a second avoiding hole 71 for the shell body 21 to penetrate and extend out, and the second end of the conductive copper bar 1 and the corresponding end of the shell body 21 penetrate the cover plate 7 through the second avoiding hole 71, so as to realize the stable assembly of the cover plate 7 and the insulating shell 2, and at the same time ensure that the second end of the conductive copper bar 1 can be normally connected to the external component. Wherein, the shape of the second avoiding hole 71 of the cover plate 7 can be designed according to the cross-sectional shape of the shell body 21 and the conductive copper bar 1, and is usually designed as a shape matched with the shape of the shell body 21, so as to ensure accurate positioning and stable fixation during assembly.
[0051] Optionally, in combination with the description of Figure 1 , Figure 2 , the copper bar assembly further includes a sealing ring 8, and the sealing ring 8 is sleeved on one end of the shell body 21 penetrating and extending out of the second avoiding hole 71.
