The connecting cable 800 may be an optical fiber, an optical cable, or an electrical cable.

[0044] The connecting cable 800 includes a redundant section, which is used to allow the connector 400 to slide in a direction away from the electronic device chip 200. Figure 2 As shown, when the tray 300 is completely in the accommodating cavity 01, the distance between the connector 400 and the socket 600 is the shortest, and the redundant section of the connecting cable 800 is in a contracted or folded state. Figure 3 As shown, when the tray 300 slides away from the electronic device chip 200, the distance between the connector 400 and the socket 600 increases, and the redundant section of the connecting cable 800 is extended or expanded. It is understood that the specific structure of the redundant section of the connecting cable 800 is not limited in this application; as long as it allows the connector 400 to move away from the socket 600 when driven by the tray 300, the connection between the connector 400 and the socket 600 can be maintained.

[0045] Optionally, when only two end plates 500 are provided on the tray 300, at least one end plate 500 includes a tail end plate 520, and the tail end plate 520 is located at the end of the tray 300 close to the electronic device chip 200.

It is understood that the specific structure of the cable organizer 50 is not limited in this application, and it is sufficient that it can mainly serve to organize the connecting cables 800.

[0049] Figure 6 This is a cross-sectional view of an electronic device according to another embodiment of the present application, referring to Figure 6 When a plurality of end plates 500 are provided on the tray 300 , at least one end plate 500 includes a rear end plate 520 and at least one intermediate end plate 530 , and the at least one intermediate end plate 530 is located between the first end plate 510 and the rear end plate 520 .

[0050] The number of intermediate end plates 530 may be one, two, or more. For example, assuming there is one intermediate end plate 530, a second gap 07 may be provided between the intermediate end plate 530 and the tray 300. The second gap 07 is used to allow the passage of the connection cable 800 connecting the electronic device chip 200 to the front row connector of the intermediate end plate 530, and / or the second gap 07 is used to allow the passage of the tail wire 20 of the electronic device 10 connected to the rear row connector of the intermediate end plate 530. The front row connector is any row of connectors 400 located on the side of the intermediate end plate 530 facing away from the electronic device chip 200, and the rear row connector is any row of connectors 400 located on the side of the intermediate end plate 530 close to the electronic device chip 200.

[0051] Optionally, a second gap 07 may be provided between the intermediate end plate 530 and the top plate 110. Alternatively, a second gap 07 may be provided between the intermediate end plate 530 and the tray 300, and between the intermediate end plate 530 and the top plate 110. The second gap 07 is used to allow the passage of a connecting cable 800 connecting the electronic device chip 200 to the front row connector of the intermediate end plate 530, and / or the passage of a tail cable 20 of the electronic device 10 connected to the rear row connector of the intermediate end plate 530.

[0052] You can continue to refer to Figure 6 The intermediate end plate 530 may be provided with a through hole 08, which is used to allow the connection cable 800 connected to the electronic device chip 200 and the front connector of the intermediate end plate 530 to pass through, and / or the second gap 07 is used to allow the tail line 20 of the electronic device 10 connected to the rear connector of the intermediate end plate 530 to pass through.

[0053] It is understandable that when there are at least two intermediate end plates 530, the wire passing method of any intermediate end plate 530 includes at least one of multiple wire passing methods, and the multiple wire passing methods include:

[0054] A second gap 07 may be defined between the middle end plate 530 and the top plate 110 , or a second gap 07 may be defined between the middle end plate 530 and the tray 300 , or a through hole 08 may be defined in the middle end plate 530 .

[0055] It is understandable that the wire passing modes of the at least two intermediate end plates 530 may be the same or different, and may be set according to actual needs.

[0056] In some optional embodiments, an indicator light is provided on the surface of the end plate 500 facing away from the electronic device chip 200, and the indicator light is used to indicate the connection status of the connector 400 and the module or the data transmission status, etc. In addition, the end plate 500 can also play the role of electromagnetic shielding.

[0057] Figure 7 This is a front view of an electronic device according to an embodiment of the present application. Figure 8 for Figure 7 Cross-sectional view at AA, refer to Figure 7 and Figure 8 The tray 300 is slidably connected to the housing 100, and a limit block 900 is provided on the inner wall of the housing 100. The limit block 900 is used to limit the maximum distance between the tray 300 and the installation area, or between the tray 300 and the electronic device chip 200. The limit distance refers to the minimum distance between the tray 300 and the installation area or the electronic device chip 200 along the sliding direction of the tray 300. When the tray 300 abuts the limit block 900, the tray 300 stops sliding toward the electronic device chip 200. At this time, the distance between the tray 300 and the electronic device chip 200 is the minimum distance between the two.

[0058] It is understandable that the present application does not limit the sliding manner of the tray 300 and the shell 100. For example, the inner wall of the shell 100 can be provided with a slide rail, and the tray 300 can be slidably connected to the slide rail.

[0059] In summary, the electronic device of the present application can significantly increase the number of ports 03 of the electronic device by providing multiple end plates 500 and multiple rows of connectors 400 without increasing the overall height of the device. Furthermore, by sliding the tray 300 so that the target end plate 500 on the tray 300 slides out of the accommodating cavity 01, sufficient space is provided for inserting and removing the electronic device 10 from the port 03 on the end plate 500. Furthermore, during the sliding process of the tray 300, the connection between the electronic device chip 200 and the connector 400 is not affected.

[0060] Obviously, those skilled in the art may make various changes and modifications to the embodiments of the present application without departing from the spirit and scope of the present application. Thus, if such modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is intended to include such modifications and variations.
