Description

Technical Field

[0001] The utility model relates to the technical field of crimping machines, in particular to a wire harness terminal crimping machine. Background Art

[0002] A wire harness terminal crimping machine is a device used to connect wires and terminals. Its main function is to firmly connect the wires and terminals together by applying pressure, ensuring that the circuit can conduct current normally. When using a wire harness terminal crimping machine, you first need to insert the end of the wire harness into the appropriate position of the crimping machine, ensuring that the insulation of the wire harness is stripped and a certain length of wire is exposed. Then, you need to adjust the crimping strength, which can usually be done with a knob or adjustment lever to ensure that the crimping strength is suitable for the insulation layer and wire diameter of the wire harness. Next, align the crimping head with the wire at the end of the wire harness, and press the operating button or foot switch to make the crimping head crimp the terminal to the wire. After the crimping is completed, you need to release the operating button or foot switch and remove the crimping head from the wire harness.

[0003] During normal crimping work, the position of the terminal is determined by manual visual inspection or simple limiters. Simple limiters have poor adjustability and cannot adapt to terminals of different specifications and lengths. Visual placement often results in deviations in the cutting size and the length of the product cannot be limited, which results in large deviations in the length of the crimped product and increases the workload of rework in the factory.
