Description

Terminal bending processing tooling Technical Field

[0001] This utility model belongs to the field of terminal bending technology, and in particular relates to a terminal bending processing tool. Background Technology

[0002] Terminals generally refer to components that connect electrical or electronic equipment. They are used to connect wires, cables, or other conductors, enabling the transmission of current or the transfer of signals between different devices. Terminals are widely used and play a vital role in electronics, power, communications, and various devices, ensuring the reliability of signal and power transmission and the stability of connections. Terminal bending devices are equipment used in industrial production or electronics manufacturing to handle the connection terminals of electronic components or wires.

[0003] Chinese patent CN217512608U discloses a “bending device for insert terminals”, which can bend insert terminals by means of a pressing wheel, but requires manual pressure to be applied to the pressure rod to bend the terminals, which is relatively labor-intensive. Summary of the Invention
