Because the electrical connection modes among the board 130 to be tested, the first adapter board 120 and the main board 110 are all plug-in connection modes, when the first adapter board 120 is assembled or replaced, only the corresponding first contact pin 150 and the first probe 160 need to be inserted or pulled out, so that the workload of wiring is effectively reduced, the assembling and disassembling operations of the circuit board testing adapter module 100 are faster, and the test efficiency of the test fixture system is favorably improved. In addition, because the first adapter plate 120 is connected with the main board 110 in a corresponding plug-in manner, when a new structure of the first adapter plate 120 is designed, only the hole positions of the test points on the first adapter plate 120 need to be changed or moved according to actual conditions, so that the design workload of the first adapter plate 120 is greatly reduced, and the board manufacturing efficiency is effectively improved. Meanwhile, the error probability and the failure rate of the jig manufactured by people are reduced, and the reliability of the test result is ensured.
