Technical Field

[0001] The utility model relates to the field of terminal installation, in particular to a stripped wire core pressing device. Background Art

[0002] In the automotive wiring harness industry, articulated terminals are one of the most critical components used to connect wires and ensure the stable operation of electrical systems. Among them, barrel terminals are a common type, which are designed to allow wires to be inserted into their interior, ensuring that the wire connection is tight and reliable. However, sometimes after stripping the outer sheath of the wire, the inner copper wire may have a diameter larger than the inner diameter of the barrel terminal due to the lack of the outer sheath.

[0003] Manual assembly cannot bind the copper wire well, which may make it difficult to insert the copper wire into the barrel terminal, and sometimes even make it impossible to insert all the copper wires into the terminal, which may pose a serious safety hazard and may cause loose wire connections, leading to electrical failures or fire risks.
