It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
The embodiment of the utility model provides a board testing arrangement is provided. Fig. 1 is a schematic structural diagram of a board testing device according to an embodiment of the present invention. As shown in fig. 1, the board card testing apparatus includes: the carrier 110, at least one board fixing module (two board fixing modules, i.e., a board fixing pressing block 121 and a board fixing stopper 122, are exemplarily shown in fig. 1, and the specific functions of the two are specifically described in the following embodiments), a socket (not shown), a socket fixing module 130, and a driving assembly 140.
The carrier 110 is used for carrying a board 210 to be tested; the board fixing module and the socket fixing module 130 are disposed on the carrier 110; the driving assembly 140 is respectively connected with the board card fixing module and the socket fixing module 130, and drives the board card fixing module and the socket fixing module 130 to move; the socket is disposed in the socket fixing module 130 and detachably connected to the socket fixing module 130.
At present, most railway products are mainly in the form of board cards, connectors are arranged at the tail ends of the board cards, and after the board cards are inserted into a cage, the board cards are connected with the connectors corresponding to a bottom plate inside the cage through the connectors, so that power supply to the board cards and connection of communication lines are achieved. Therefore, when the board card is tested, not only the performance of the board card needs to be tested, but also whether the connector fails or not needs to be tested. For the above reasons, when the board test apparatus is used for testing, the connector 220 at the end of the board 210 to be tested is not removed, but is placed on the carrier 110. The socket in the device is directly butted with the connector 220 so as to simultaneously complete the test of the board card 210 to be tested and the connector 220. In the testing process, the connector 220 is required to supply power to the board card 210 to be tested, and meanwhile, the connector 220 is required to lead out all external signals of the board card 210 to be tested, so that various signals are simulated to perform functional tests on the board card 210 to be tested.
