[0002] Electronic wiring harness refers to a low-voltage electronic wire group. It establishes a connection between two or more isolated and different electronic circuits to realize the flow of current or signal and realize the various functions of each electronic component. Electronic wiring harness is widely used in household appliances, automobile lighting, digital communications and other fields. The terminals are punched at both ends of the wire, and then the terminals at both ends of the wire are inserted into the plug shell to form an electronic wiring harness with a double-ended plug shell. When in use, the electrical equipment is directly connected by plugging. The structure of the terminal machine currently on the market is complex, requiring manual cooperation, difficult to operate, time-consuming and labor-intensive, and the quality of the wire is uneven, affecting production efficiency. When the current terminal machine inserts the two ends of the wire into the plastic shell, when the position of the terminal and the plastic shell are not aligned, it is necessary to rotate the wire clamp to align the terminal with the plug hole of the plastic shell, and then insert the terminal crimped at the end of the wire into the plastic shell. The process is complicated and requires more actions for correction, which affects production efficiency. Utility Model Content

The translation block 64 moves with the nut seat 65, and after the wire transfer clamp 62 clamps the wire, it follows the movement of the translation block 64 to convey the wire to the crimping mechanism 4 to make terminal blocks at both ends of the wire.

[0077] The transfer motor 63 drives the horizontal screw rod 64 to rotate, and the nut seat 65 is threadedly connected to the horizontal screw rod 64 to drive the linear motion of the nut seat 65. The translation block 61 is arranged on the nut seat 65, and the line moving clamp 62 is arranged on the translation block 61. In this embodiment, the horizontal motion of the translation block 61 is driven by the transfer motor 63 to rotate the horizontal screw rod 64, and then drives the nut seat 65 to move linearly, and drives the translation block 61 to move linearly through the nut seat 65. In other embodiments, the horizontal motion of the translation block 61 can also be achieved by electric cylinder drive or cylinder telescopic action.
