[0043] The terminal lug 2 is arranged below the wire clamping device 1 . The terminal lug 2 is a sheet-like structure extending in the height direction. The terminal lug 2 is adapted to the mounting groove 12 of the mounting portion 11 . The terminal lug 2 can slide up and down in the mounting groove 12 of the mounting portion 11 .

[0044] After the lug 2 is fixed, the clamping device 1 is aligned with the lug 2 in the horizontal direction, and then the clamping device 1 is driven to move from top to bottom. When the lug 2 contacts the clamping device 1, it is detected whether the lug 2 is aligned with the mounting groove 12. If not, the position of the clamping device 1 in the horizontal direction is adjusted so that the lug 2 is aligned with the mounting groove 12. After the lug 2 is aligned with the mounting groove 12, the clamping device 1 is driven to move downward so that the lug 2 is inserted into the mounting groove 12.

[0045] The limiter has a certain elasticity. When the terminal piece 2 is inserted into the mounting groove 12, the limiter is deformed. The deformed limiter abuts against the terminal piece 2, so that the limiter guides the insertion process of the terminal piece 2 and prevents the terminal piece 2 from moving forward and backward.

[0046] The limiting member and the bottom surface of the mounting portion 11 together form a mounting groove 12, the size of the mounting groove 12 is the same as the size of the terminal piece 2, or when the limiting member is elastic, the size of the mounting groove 12 is smaller than the size of the terminal piece 2. After the terminal piece 2 is inserted into the mounting groove 12, the limiting member is deformed so that the size of the mounting groove 12 is the same as the size of the terminal piece 2.

[0052] The first curved portion 131 and the second curved portion 132 are elastic, and when the terminal piece 2 contacts the mounting groove 12, the first curved portion 131 and the second curved portion 132 are deformed, so that the terminal piece 2 is inserted into the mounting groove 12. When the top of the terminal piece 2 moves to the top of the mounting groove 12, the wire clamping device 1 stops moving downward, and the first curved portion 131 and the second curved portion 132 rebound to their original shapes, and at this time, the first curved portion 131 and the second curved portion 132 press the terminal piece 2.
