Exceeding the standard for radiated emission (RE) in EMC tests is a common problem with Ethernet interfaces. In the past, dedicated connectors were usually used to solve this problem for Ethernet interfaces. However, there are many connectors in smart cockpit products. Adding dedicated Ethernet connectors not only takes up space on the printed circuit board (PCB), but also increases production costs.

[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1 The utility model provides a connector assembly that can be used in a smart cockpit product, which includes a shell 1, a main connector unit 2 and at least one Ethernet connector unit 3.

[0030] The housing 1 is provided with a receiving chamber 101, and the main connector unit 2 and at least one Ethernet connector unit 3 are both provided in the receiving chamber 101. The housing 1 may be a plastic housing, but is not limited thereto.

[0031] The main connector unit 2 includes a plurality of first pins 201, and the plurality of first pins 201 are arranged at intervals from each other. The number of the plurality of first pins 201 may be determined according to actual conditions. For example, the main connector unit 2 of this embodiment may include 40 first pins 201.

[0032] Each Ethernet connector unit 3 includes a signal shielding layer 301 and at least two second pins 302. The signal shielding layer 301 is arranged on the periphery of the at least two second pins 302, and the first pin 201 and the second pin 302 are isolated by the signal shielding layer 301. The signal shielding layer 301 is used to shield signals. Since the signal transmitted by Ethernet is a high-speed signal, the signal shielding layer 301 is used to isolate the first pin 201 and the second pin 302 to avoid the signal transmitted by Ethernet from interfering with the signal transmitted by the first pin 201.

[0033] Furthermore, in the length direction of the second pin 302 , the length of the signal shielding layer 301 is greater than or equal to the length of the second pin 302 , ensuring that the second pin 302 is within the effective shielding range of the signal shielding layer 301 , thereby ensuring the shielding effect of the signal shielding layer 301 .

[0034] The signal shielding layer 301 is made of metal material, such as copper or aluminum, but not limited thereto.

[0035] In this embodiment, the connector assembly includes a main connector unit 2 and an Ethernet connector unit 3, and the main connector unit 2 and the Ethernet connector unit 3 are arranged side by side in the housing 1, wherein the main connector unit 2 is located on one side of the accommodating cavity 101, and the Ethernet connector unit 3 is located on the other side of the accommodating cavity 101. In this embodiment, the Ethernet connector unit 3 is placed at the edge of the connector assembly, so that the main connector unit 2 and the Ethernet connector unit 3 are integrated into one body and maintain a certain degree of independence from each other, so as not to interfere with each other, thereby further reducing the influence of the high-speed signal transmitted by the Ethernet on the main connector unit 2.

[0036] See also Figure 2 In another embodiment of the utility model, the connector assembly includes a main connector unit 2 and at least two Ethernet connector units 3. The specific number of Ethernet connector units 3 can be set according to actual conditions. For example, the number of Ethernet connector units 3 can be two, three or four, which is not limited here. The main connector unit 2 is located in the middle of the accommodating cavity 101, and at least two Ethernet connector units 3 are respectively located on opposite sides of the main connector unit 2, so as to keep the main connector unit 2 and the Ethernet connector unit 3 from interfering with each other as much as possible.

[0037] Alternatively, at least two Ethernet connector units 3 are located on one side of the accommodating cavity 101, and the main connector unit 2 is located on the other side of the accommodating cavity 101. In this way, all Ethernet connector units 3 can be concentrated on the same side edge of the connector assembly, thereby reducing the impact of high-speed signals transmitted by Ethernet on the main connector unit 2.

[0038] When the connector assembly includes a plurality of Ethernet connector units 3, two adjacent Ethernet connector units 3 are spaced apart from each other, which can not only avoid mutual influence, but also facilitate the plugging of the external adapter device and the connector assembly.

[0039] See also Figure 3 The Ethernet connector unit 3 includes a signal shielding layer 301, two second pins 302 and a plastic part 303. The two second pins 302 and the plastic part 303 are both located in the signal shielding layer 301. The two second pins 302 are arranged opposite to each other. The signal shielding layer 301 and the two second pins 302 are separated by the plastic part 303 to prevent the signal shielding layer 301 from affecting the signal transmission of the second pins 302.

[0040] The cross-sectional shape of the signal shielding layer 301 is elliptical, circular or rectangular, and only needs to be able to surround the two second pins 302 .

[0041] The Ethernet connector unit 3 of this embodiment is formed by removing the plastic shell of the special connector used in the previous Ethernet interface and retaining the signal shielding layer and the Ethernet metal pin (i.e., the second pin). The main connector unit 2 and the Ethernet connector unit 3 are integrated into an integral structure, which can make the overall structure of the connector assembly simple and small in volume on the basis of meeting the EMC experimental radiation requirements, save the design space of the circuit board, and reduce the production cost.

[0042] Please continue reading Figure 1 In the connector assembly of the present invention, the main connector unit 2 may further include a plurality of positioning posts 202, and the plurality of positioning posts 202 are spaced apart from each other. When the connector assembly is plugged into an external adapter device, the plurality of positioning posts 202 may limit the external adapter device to prevent the connector assembly and the external adapter device from loosening or shifting in position to cause poor contact.

[0043] It is understandable that the external adapter device has grooves adapted to the positioning posts 202 at positions corresponding to the plurality of positioning posts 202. After the connector assembly is plugged into the external adapter device, the positioning posts 202 can be snapped into the grooves to fix the connector assembly and the external adapter device.

[0044] The present invention also provides a cockpit electronic device, which can be applied to a smart car, and includes a connector assembly as described in any of the above embodiments. Since the cockpit electronic device includes the connector assembly of the above embodiment, the cockpit electronic device of the present invention also has all the technical effects of the above connector assembly, which will not be described in detail here.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
