Problems solved by technology
[0003] If the commonly used manual plug-in test is used, it will not only be time-consuming and laborious, but also difficult to achieve the purpose of tens of thousands of verifications
Similar linear reciprocating mechanisms have been used in the furniture industry, such as the device for opening and closing times of drawers or cabinet doors. This device cannot realize the reciprocating counting function and stop the action midway and perform functional testing on the board.
Moreover, the corresponding device can only verify the mechanical properties of the tested sample, but cannot automatically test the function and performance of the tested electronic product
If manual plugging and unplugging is used to perform aging tests on board slots and metal contacts, it is time-consuming and laborious, and it is difficult to achieve sufficient verification times; devices that use furniture such as drawers, doors, etc. for switch test verification cannot be tested during mechanical movement. Complete functional and performance testing of electronic products

The invention discloses a case backplane connector service life test device, which is connected with a tested board on a tested case, and comprises a control module, a test module, a motor, a motion module, a photoelectric counter and relays A and B. The invention also discloses a test method for the case backplane connector service life test device. Thus, multiple times (tens of thousands of times) automatic plug and pull on the board can be completed, no person is involved, and the plug-pull times can be counted; during the board plug-pull period (after a plurality of times of plug and pull), the function and the performance of the board can be tested automatically; and fully-automatic plug and pull and function and performance test on electronic features of a sample can be realized.
Description
technical field [0001] The invention relates to the technical field of nuclear power DCS testing in the nuclear power industry, in particular to a life testing device and testing method for chassis backplane connectors. Background technique [0002] In the reliability test of DCS system in nuclear power plant, it is necessary to verify the aging characteristics of some mechanical structures. After summarizing the feedback from engineering practice, it is a very important indicator for the aging characteristics of chassis card insertion and removal. This test can verify the reliability of the mechanical structure of the chassis, board and chassis backplane and the rationality of the PCB process. [0003] If the commonly used manual plug-in test is used, it will not only be time-consuming and laborious, but also difficult to achieve the purpose of tens of thousands of verifications. Similar linear reciprocating mechanisms have been used in the furniture industry, such as the...
