[0042] The working principle of the automatic test mechanism of fuse braider of the utility model is as follows:

[0043] First, the fuse is sent to test wheel 1 (the fuse can be sent to test wheel 1 by the chain conveying device of fuse braider), so that the two pins of fuse are inserted into test groove 111 of two test discs 11 of test wheel 1 respectively, so that the fuse can be driven by test wheel 1, and the two pins of fuse are respectively rested on supporting outer arc surface 21 of two test tracks 2,

[0045] After the resistance testing instrument completes the test on the fuse, the test press mechanism 3 releases the pressing of the two pins of the fuse, and the test wheel 1 continues to drive the fuse to move into the next process.

[0046] As can be seen from the above, when testing the fuse, the two pins of the fuse are pressed by the test press mechanism 3 to stably abut against the test electrode 22 of the two test tracks 2, respectively, so that the two pins of the fuse form stable electrical conduction with the two test electrodes 22, thereby ensuring the stability and accuracy of the test on the fuse.
