In this example, the board 1 is an integrated circuit board, which ensures that the board 1 has sufficient rigidity and circuit connection capability to support the installation and data transmission requirements of the CFP module 6.

[0042] The board 1 includes multiple CFP module connectors 2 disposed thereon, each CFP module connector 2 correspondingly connected to a CFP module 6. The CFP module connectors 2 are arranged in an array, totaling six. The board 1 includes an external connection portion 3 disposed thereon. In the illustrated example, a data interface 301 is disposed on a side edge of the board 1. The external connection portion 3 has at least one data interface 301. The data interface 301 is an interface that can be connected to any host computer or ECU, such as a SATA or USB interface.

[0043] Each of the data interfaces 301 is correspondingly provided with a plurality of pins 302 embedded in the board body 1, and the pins 302 are signal-connected to the data interfaces 301. In some cases, the pins 302 are circuit-connected to the data interfaces 301 to ensure reliability and stability of signal transmission.

[0044] In this example, the board 1 is an integrated board, including at least a signal layer (not shown) within the board 1. This signal layer includes wiring circuitry, through which each CFP module 6 is interconnected with a different pin 302. In this embodiment, the board 1 is provided with multiple CFP module connectors 2 connected to a single external interface, and the corresponding signal layer wiring circuitry is provided, enabling data collection and transmission from each CFP module 6 on a single test board.

[0045] In one example of this embodiment, reference may be made to Figure 2 It is understood that the CFP module connection portion 2 includes an operating status receiving terminal 201 for receiving and monitoring the operating status of the CFP module 6. The operating status receiving terminal 201 extends from the signal layer to the board body 1 and is connected to the CFP module 6 to be tested, ensuring its connection and data transmission with the CFP module 6 to be tested. The operating status receiving terminal 201 extends from the signal layer to the board body 1.

[0046] And an operating status output terminal, the operating status output terminal is connected to the external connection part 3 through the signal layer (not shown in the connection structure diagram). The connection between the operating status output terminal and the external connection part 3 can be any circuit. The specific method of achieving circuit connection can be designed by those skilled in the art according to actual needs and will not be described in detail here.

[0047] Second embodiment

[0048] Based on the above embodiment, in this example, Figure 1 The CFP module connection portion 2 shown also includes a voltage testing unit spaced between the operating status receiving terminal 201 and the operating status output terminal. The voltage testing unit can be embedded and integrated into the structure of the CFP module connection portion 2 to ensure a tight and stable connection with the CFP module 6 under test. The voltage testing unit can monitor voltage values ​​in real time through voltage-sensitive resistors or measurement chips within the voltage testing unit, collect various voltage values ​​required by the CFP module 6 under test, and is integrated with a data processing unit. The acquired voltage information is transmitted to the data processing unit on the test board for processing and analysis, and the voltage status of the CFP module 6 under test is monitored and recorded in real time, thereby evaluating the stability and performance of its power supply system.

[0049] In this example, the board 1 further includes a plurality of indicator lights 4 disposed thereon. Each indicator light 4 is connected to a voltage testing unit, which sends a corresponding instruction to the indicator light 4 according to the voltage status. When the voltage is normal, the indicator light 4 lights up, and when a fault occurs, the indicator light 4 goes out or changes color.

[0050] Based on the structure disclosed in this example, the voltage status of the CFP module 6 to be tested can be independently displayed, and personnel can be informed immediately when a voltage problem occurs.

[0051] Third embodiment

[0052] Based on the above embodiments, Figure 1-2As shown in the results, in this example, the board 1 further defines a plurality of through holes 5, each corresponding one-to-one with the CFP module connection portion 2. The through holes 5 are used to accommodate the optical fiber connectors of the CFP modules 6 to be tested. These through holes 5 allow external light to pass through to the CFP modules 6. Therefore, the board 1 in this embodiment can be placed in an information transfer station or other scenario requiring a large number of CFP modules 6. Different CFP modules 6 can be connected via the through holes 5, while a host computer can be connected via the external connection portion 3 to monitor the operating status of the multiple CFP modules 6 in real time.

[0053] Fourth embodiment

[0054] Based on the above embodiments, combined with Figure 3 In the structure shown, at least one pair of sliding engaging portions 7 is further provided at each edge of the plate body 1 in this example.

[0055] In this example, the sliding engaging portion 7 is a rectangular strip-shaped structure 701 disposed at the edge of the plate 1. A plurality of balls 702 are embedded in an array above and below the strip structure 701. The balls 702 are partially hidden within the strip structure 701 and partially protrude from the strip structure 701. Typically, the plate 1 needs to be inserted into a multi-layer box, which is typically provided with a plurality of ribs with grooves (not shown). The grooves in the ribs are used to slide and insert the plate 1. In some cases, due to the high friction between the grooves and the ribs, the plate 1 may be damaged during insertion. Therefore, the structure in this example can achieve the function of reducing friction through the balls 702, thereby preventing damage to the plate 1.

[0056] In some preferred examples, reference Figure 4 To understand, each of the sliding engaging portions 7 is provided with at least two sets of parallel balls 702, and the volume of each ball 702 hidden within the sliding engaging portion 7 is no less than half of its total volume. As shown in the figure, the main volume of the ball 702 is provided within the strip structure 701, thereby ensuring that it is fixed within the strip structure 701 and does not slip. This method has low manufacturing costs and does not require a separate fixing structure, but only requires the ball 702 to be embedded therein.

[0057] In some preferred examples, the sliding engaging portion 7 further includes an elastic material (not shown in the figure) provided between the cavity 703 in which the ball 702 is embedded and the embedded ball 702. Figure 4 As shown, a certain gap may be left between the cavity 703 of the ball 702 and the embedded ball 702, and the gap may be filled with elastic material so that the plate 1 can have a certain flexibility during the process of taking out and putting in the aforementioned ribs.

[0058] Fifth embodiment

[0059] Based on the above embodiment, the structure of this example is referenced Figure 5 For better understanding, the plate body 1 further includes a clip 8 provided on one side of the plate surface. The clip 8 includes a reference portion 801 fixedly connected to the plate body 1, a rotating rod 802 extending from the reference portion 801, and a rotating engaging portion 803. The rotating engaging portion 803 is a rectangular block with a protrusion at one end, and the protrusion is located at the end away from the plate body 1.

[0060] The middle section of the rotating fastening portion 803 is provided with a rotating hole 804, which cooperates with the rotating rod 802 to form a rotating connection structure. It is easy to understand that the rotating fastening portion rotates around the rotating rod 802, and then the CFP module 6 to be tested can be fastened and unlocked. Therefore, the height of the lower surface of the protrusion is consistent with the height of the CFP module 6 to be tested. Specifically, the protrusion will limit the movement of the CFP module 6 after the fastening is completed, which can be referred to Figure 5-6 Understand the snap-in process.

[0061] Although the present invention 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; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
