This application claims the benefit of Chinese Application Serial No. 202010953122.8, filed Sep. 11, 2020, which is hereby incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a detection system, and more particularly to a detection system for non-standard connection interface through an adapter card.

2. Description of the Related Art

In the conventional motherboard test for a non-standard connection interface, a specific connection line corresponding to the non-standard connection interface is required to connect the non-standard connection interface to an adapter card of a standard BSI (Boundary Scan Inspection) development test fixture, so that the test can be performed on the non-standard connection interface through the standard BSI development test fixture.

In the above test conditions, it is necessary to customize specific connection lines for different non-standard connection interfaces; however, the non-standard connection interfaces are only used in specific order cases, so the customizations of the specific connection lines may cause high cost and be limited by patent rights of the non-standard connection interfaces. Therefore, it inconvenient to produce specific connection lines.

Furthermore, the specific connection line and the non-standard connection interface generally are electrically connected by metal engaging structures, and the repeated connection and removal operations during the test process may easily damage metal engaging structures of the non-standard connection interface and the specific connection line, to cause incorrect test results for non-standard connection interfaces.

Therefore, what is needed is to develop an improved technical solution to solve the conventional problem that the detection for the non-standard connection interface of the motherboard is inconvenient and the accuracy of the detection result is not good enough.

SUMMARY OF THE INVENTION

In order to solve the conventional technical problems that the detection for a non-standard connection interface of a motherboard is inconvenient and the accuracy of the detection result is not good enough, the present invention provides a detection system for non-standard connection interface through an adapter card.

The present invention provides a detection system for non-standard connection interface including a motherboard and an adapter card, a first assembly, a second assembly, a standard test adapter card, and a standard BSI development test fixture; the adapter card includes a non-standard connection interface, a first standard connection interface, and a plurality of fastening slots; the standard test adapter card includes a plurality of second standard connection interfaces and a plurality of first standard BSI development test fixture connection interfaces.

The motherboard includes a plurality of motherboard non-standard connection interfaces, and type ratios of circuits connected to the plurality of motherboard non-standard connection interfaces are different;

The non-standard connection interface of the adapter card is configured to electrically connect to one of the plurality of motherboard non-standard connection interfaces. The first standard connection interface of the adapter card is electrically connected to the non-standard connection interface. The plurality of fastening slots of the adapter card is disposed on the adapter card.

The first assembly includes a plurality of snaps corresponding in position to the plurality of fastening slots of the adapter card one by one, and the snaps of the first assembly are configured to insert through the fastening slots of the adapter card to make the first assembly and the adapter card fasten and engage with each other.

The second assembly includes a plurality of engaging slots and a standard connection interface through slot. The first assembly is engaged and fastened with the adapter card, the plurality of snaps of the first assembly are then inserted through the plurality of engaging slots of the second assembly, respectively, and the first standard connection interface is inserted through the standard connection interface through slot, to make the first assembly, the adapter card and the second assembly engage and fasten with each other.

Each of the plurality of second standard connection interfaces of the standard test adapter card has the different number of pins, and one of the second standard connection interfaces is selected to electrically connect to the first standard connection interface according to the number of pins of each of the plurality of second standard connection interfaces and the type ratio of the circuits connected to each of the plurality of motherboard non-standard connection interfaces. The plurality of first standard BSI development test fixture connection interfaces of the standard test adapter card are electrically connected to the plurality of second standard connection interfaces.

The standard BSI development test fixture includes a second standard BSI development test fixture connection interface configured to electrically connect to the plurality of first standard BSI development test fixture connection interfaces. The standard BSI development test fixture is electrically connected to the plurality of first standard BSI development test fixture connection interfaces through the second standard BSI development test fixture connection interface and performs test on the connected one of the motherboard non-standard connection interfaces of the motherboard.

According to the above-mentioned content, the difference between the present invention and conventional technology is that the snaps of the first assembly can be inserted through the fastening slots of the adapter card to make the first assembly and the adapter card fasten and engage with each other, and the snaps of the first assembly are further inserted through the engaging slots of the second assembly to make the first assembly, the adapter card and the second assembly engage and fasten with each other; the motherboard is electrically connected to the adapter card, the adapter card is electrically connected to the standard test adapter card, and the standard test adapter card is electrically connected to the standard BSI development test fixture, so as to provide restraining protection for the adapter card and improvement of stability in detection for the non-standard connection interface.

Therefore, the technical solution of the present invention can provide restraining protection for the adapter card and improvement of stability in detection for the non-standard connection interface.
