Description

Technical Field

[0001] This invention relates to the technical field of motherboard testing, and in particular to a combined test module for server motherboards. Background Technology

[0002] In the consumer electronics industry, the USB Type-C interface has become widely adopted, and USB Type-C communication cables, as supporting accessories, have a vast market. They are widely used in common electronic products, serving as the carrier for charging and data exchange in terminal products such as mobile phones, laptops, desktop computers, digital cameras, headphones, external hard drives, projectors, and game consoles, creating a significant market demand. Testing Type-C devices requires a Type-C interface. Besides basic USB data transfer functions, the USB Type-C interface can also fully transmit DP signals and supports the USB PD 2.0 standard. Factory production testing of Type-C ports is cumbersome. It involves USB 2.0 and USB 3.0 interchangeability testing, DP function testing via an external adapter connected to a monitor, PD function testing by connecting to a device to check charging status, and reversible insertion testing requiring manual plugging and unplugging. The entire testing process is tedious and inefficient.

[0003] Currently, PCBA boards, Type-C, and USB test modules are simultaneously fixed using equal-height screws and springs, and are inserted and removed at the same time. For example, Chinese patent CN219625678U discloses an automotive wiring harness testing module for non-probe contact interfaces. The Type-C and USB test module interfaces cannot be quickly inserted and removed, resulting in low testing efficiency, inconvenient maintenance, high cost, and a tendency for overall floating during insertion and removal, making it difficult to individually compensate for travel distance and leading to unstable testing. Therefore, it is necessary to provide a combined test module for server motherboards that is compact, easy to maintain, and can solve the problem of not being able to individually compensate for travel distance during rapid insertion and removal, thereby improving testing stability and production efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a combined test module for server motherboards. It has a compact structure, is easy to maintain, and can solve the problem of not being able to compensate for the travel distance during rapid plugging and unplugging, which is conducive to improving test stability and production efficiency.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes an installation plate, a USB adapter card, and a Type-C adapter card.

A first compression spring is provided between the first floating block and the installation plate. The second floating block is connected to the installation plate by a spring column. The USB adapter card passes through the installation plate and is connected to a first connection port via the first floating block. The Type-C adapter card passes through the installation plate and is connected to a second connection port via the second floating block.

[0006] As can be seen from the above solution, both the USB adapter and the Type-C adapter adopt an independent floating method, which does not affect each other, is convenient to maintain, can solve the problem of not being able to compensate for the stroke during rapid insertion and removal, is conducive to improving test stability and production efficiency, is suitable for the environment of compact connectors, and can achieve independent floating in limited space.

Detailed Implementation

[0012] like Figures 1 to 5 As shown, in this embodiment, the present invention includes an installation plate 1, a USB adapter card 2, and a Type-C adapter card 3. The installation plate 1 is provided with a first floating block 4 and a second floating block 5. The first floating block 4 is connected to the installation plate 1 by a first equalizing screw 6. A first compression spring 7 is provided between the first floating block 4 and the installation plate 1. The second floating block 5 is connected to the installation plate 1 by a spring post 8. The USB adapter card 2 passes through the installation plate 1 and the first floating block 4 and is connected to a first connection port 9. The Type-C adapter card 3 passes through the installation plate 1 and the second floating block 5 and is connected to a second connection port 10.

[0013] The USB adapter 2 is used to connect a USB cable. During the connection process, the first equal-height screw 6 and the first compression spring 7 provide floating support. The Type-C adapter 3 is used to connect a Type-C cable. During the connection process, the elastic post 8 provides floating support, effectively improving the stability of the connection and avoiding forced insertion. Both the USB adapter 2 and the Type-C adapter 3 adopt an independent floating method, which does not affect each other, making maintenance convenient. It can solve the problem of not being able to compensate for the stroke independently during rapid insertion and removal, which is conducive to improving testing stability and production efficiency. It is suitable for compact connector environments and can achieve independent floating in limited space.

[0014] like Figures 1 to 3 As shown, in this embodiment, there are four sets of the first equal-height screws 6. The first floating block 4 is located below the mounting plate 1. The four sets of the first equal-height screws 6 are symmetrically distributed and pass through the mounting plate 1 to connect with the first floating block 4. There are two sets of the first compression springs 7, which are symmetrically distributed between the first floating block 4 and the mounting plate 1. This symmetrically distributed structure improves the stability of the connection.

[0015] like Figures 1 to 3As shown, in this embodiment, there are four sets of elastic columns 8. The second floating block 5 is located below the mounting plate 1. The four sets of elastic columns 8 are symmetrically distributed and pass through the mounting plate 1 to press against the second floating block 5. The second floating block 5 is connected to the bottom of the elastic columns 8 by a second equal-height screw 14. The use of multiple symmetrically distributed sets is beneficial to improving the stability of the connection.

[0016] like Figures 1 to 3 As shown, in this embodiment, the elastic column 8 includes a cylindrical body 11, inside which a plunger 12 is disposed. A second compression spring 13 is sleeved on the plunger 12, and the second compression spring 13 engages with the cylindrical body 11 in a pressing fit. The bottom of the plunger 12 is threadedly connected to the second equalizing screw 14. During the insertion process, the second compression spring 13 engages with the cylindrical body 11 in a pressing fit, providing a floating support function.

[0017] like Figures 1 to 3 As shown, in this embodiment, the USB adapter card 2 and the Type-C adapter card 3 are both arranged vertically, the first equalizing screw 6, the first compression spring 7, and the elastic column 8 are all arranged vertically, the first floating block 4 and the second floating block 5 are arranged side by side adjacent to each other, and the first connection port 9 and the second connection port 10 are both connected to an external testing machine.

[0018] When using the elastic post 8 and the second equalizing screw 14, the floating stroke can be compensated separately during insertion and removal, and the module is fixed in the center. During later maintenance and replacement, the second equalizing screw 14 can be removed and the Type-C adapter fixing block can be taken out to quickly replace the adapter, which has good compatibility.

[0019] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
