[0012] There is a gap between the inner wall of the opening and the outer wall of the power connector;

[0013] There is a gap between the inner wall of the opening and the outer wall of the signal connector.

[0014] In some embodiments, two openings are provided, spaced apart along the height direction intersecting the shielding component;

[0015] The two openings are respectively set to correspond one-to-one with the power connector and the signal connector.

[0016] In some implementations, the shielding component includes:

[0017] The first shielding element is disposed on the insulating element, and a first notch is provided on the side wall of the first shielding element;

[0018] The second shielding component is fastened to the first shielding component, and a second notch is provided on the side wall of the second shielding component;

[0019] The domain controller is detachably mounted in at least one of the first shielding and / or the second shielding;

[0020] The first shielding element and the second shielding element together form a shielding cavity, and the first notch and the second notch together form an opening.

[0021] In some embodiments, two first notches are provided, spaced apart along the height direction intersecting the shielding component;

[0022] There are two second notches, spaced apart along the height direction intersecting the shielding component.

[0023] The two first gaps and the two second gaps are set to correspond one-to-one.

[0024] In some embodiments, the first shield has a groove and a slot communicating with the groove, the groove extending toward one end closer to the domain controller;

[0025] Along the height direction of the shielding component, the slots are spaced apart from the domain controller;

[0058] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0059] In the prior art, Ethernet conducted emission performance typically involves electromagnetic interference (EMI) and electromagnetic compatibility (EMC) issues generated by Ethernet devices when transmitting data.

[0060] Electromagnetic interference (EMI) refers to the electromagnetic radiation generated by Ethernet devices during operation, which may interfere with the normal operation of other electronic devices. Electromagnetic compatibility (EMC) means that Ethernet devices not only need to limit the interference they generate, but also need to be able to operate normally in environments where interference from other devices is present.

[0061] When designing a domain controller, it is necessary to consider switching power supply noise and digital signal harmonic interference. Therefore, it is necessary to verify the conducted interference generated by the domain controller through power lines (i.e., DC lines) and communication cables (i.e., signal lines).

[0062] To overcome the shortcomings of existing technologies, insulating components can be added to provide insulation support for the shielding assembly. The shielding assembly allows for the placement of the domain controller and forms a signal shielding field to electromagnetically shield the domain controller placed within the shielding cavity. The openings, and the gap between the inner wall of the opening and the outer wall of the power connector, allow noise or harmonics generated by the power components and connectors to be transmitted to the outside of the shielding assembly through the openings. Similarly, the gap between the inner wall of the opening and the outer wall of the signal connector allows noise or harmonics generated by the signal components and connectors to be transmitted to the outside of the shielding assembly through the openings. By capturing this noise or harmonics, it is convenient to obtain information about noise or harmonics present in the domain controller design, allowing designers to optimize the domain controller based on this information. Compared to testing at the finished product stage of the domain controller, the above testing method has the advantage of being simpler.

[0063] Therefore, the conducted emission simulation device provided in the embodiments of this application can solve the problem of high testing difficulty when testing domain controllers.

[0064] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

The shielding component 200 is disposed on the insulating component 100 and has a shielding cavity 201 and an opening 202 communicating with the shielding cavity 201. The shielding cavity 201 is used to accommodate a domain controller 10. The power connector 11 and the signal connector 12 of the domain controller 10 are respectively disposed through the opening 202. The power supply component 300 is conductively connected to the power connector 11 of the domain controller 10, and the signal component 400 is conductively connected to the signal connector 12 of the domain controller 10. There is a gap between the inner wall of the opening 202 and the outer wall of the power connector 11, and there is a gap between the inner wall of the opening 202 and the outer wall of the signal connector 12.
