Abstract
The utility model relates to a mechanism used for testing magnetic cores. The mechanism comprises a test bench board, a vertical board fixedly arranged on the test bench board, and a probe fixing board which is hinged on the upper part of the vertical board in a pitching and rotating manner, wherein one end of the probe fixing board, which is far away from the vertical board, is provided with at least one testing probe; and the test bench board is provided with at least one contact which electrically contacts with corresponding testing probes when the corresponding testing probes move downwards to the test bench board. When the mechanism used for testing the magnetic cores is in use, the testing probes and the corresponding contacts are respectively connected with a testing instrument through leads, then nanocrystalline magnetic core is placed on the test bench board below the testing probes, and the probe fixing board is pressed downwards to enable the testing probes to be electrically connected with the corresponding contacts so as to form a loop which is linked with the nanocrystalline magnetic core, thus the test can be realized. The mechanism is very convenient and efficient, and can perform fast and batched on-line testing.
