[0035] Working principle: the fixed assembly 7 can be driven by the driving motor 8, so that the fixed assembly 7 drives the clamping assembly 10 to clamp the wire 5, and moves on the positioning assembly 6 through the fixed assembly 7, and drives the clamping assembly 10 through the transmission assembly 9, so that the clamping assembly 10 pulls and twists the wire 5, and moves the clamping plate 1004, so that the pressing assembly 11 presses the wire silk on the left side of the wire 5 before the wire 5 is inserted into the terminal 4, and the wire 5 is sent into the terminal 4 through the extrusion of the clamping plate 1004 and the terminal 4, and after the terminal 4 is closed, the upper pressing plate 1001 and the lower pressing plate 1002 are opened and reset.
[0036] Specifically, the threaded rod 704 can be driven by the driving motor 8, and the upper pressing plate 1001 and the lower pressing plate 1002 are limited by the limiting rod 703, so that the threaded rod 704 drives the upper pressing plate 1001 and the lower pressing plate 1002 to clamp and fix the wire 5, at this time, the moving block 1007 is located at the starting point of the limiting groove 1010 close to the upper pressing plate 1001 and the lower pressing plate 1002, so that the clamping plate 1004 is not in close contact with the left side of the upper pressing plate 1001 and the lower pressing plate 1002, but a certain space is left between the clamping plate 1004 and the left side of the upper pressing plate 1001 and the lower pressing plate 1002, at this time, the clamping plate 1004 clamps the wire silk exposed by the wire 5, and the right side of the clamping plate 1004 is close to the wire sheath of the wire 5, then the fixed frame 701 moves to the right on the electric slide rail 602, and at the same time, the gear two 905 on the fixed assembly 7 rotates due to the meshing of the rack one 603, so that the gear two 905 drives the gear one 902 through the pawl 904 and the ratchet groove 903, the gear one 902 drives the rack two 901, so that the rack two 901 pushes the pushing frame 906 to the left, and the pushing frame 906 drives the limiting frame 1003 to move to the left.
[0037] When the limiting frame 1003 moves to the left, the clamping plates 1004 on the upper pressing plate 1001 and the lower pressing plate 1002 will move to the left, and the clamping plates 1004 are connected with the connecting plates 1006 on the right side, and the connecting plates 1006 are connected with the moving blocks 1007, so that the moving blocks 1007 on the connecting plates 1006 move in the limiting grooves 1010 during the movement of the clamping plates 1004 to the left, so that the upper clamping plate 1004 moves backward and the lower clamping plate 1004 moves forward, and in this process, the two clamping plates 1004 rub and twist the wires 5, and in the process of stable left movement of the clamping plates 1004, the wires 5 on the wires 5 are straightened.
[0038] When the clamping plates 1004 are about to be attached to the terminal 4, the grooves on the upper and lower clamping plates 1004 will be aligned at this time, and the connecting rod 1102 will be on top of the pressing block 1008 at this time, and the pressing block 1008 will press the connecting rod 1102 and the compression spring 1103 to make the compression plate 1101 move downward, and the front end of the wire is pressed and flattened by the compression plate 1101.
[0039] When the grooves on the upper and lower clamping plates 1004 are aligned, the connecting rod 1102 enters the limiting slot 1009, and no longer presses the wires 5, and at this time, the gear two 905 is in the gap of the rack one 603, and the left end of the clamping plate 1004 is attached to the terminal 4, and the fixed frame 701 continues to move to the left through the electric sliding rail 602, and the clamping plate 1004 is pressed while the clamping plate 1004 moves backward, and the moving block 1007 on the connecting plate 1006 connected to the rear of the clamping plate 1004 enters the vertical right moving channel, avoiding the dislocation of the clamping plate 1004 affecting the wires 5, until the moving block 1007 enters the limiting groove 1010 close to the triangular intersection position on the rear side, at this time, the wires 5 are completely inserted into the terminal 4, and the right side of the clamping plate 1004 is attached to the upper pressing plate 1001 and the lower pressing plate 1002, and the wire sheath on the wires 5 is on the outside of the wires 5, which can avoid the exposure of the wire on the wires 5 to the outside of the terminal 4.
