Precautions for Crimping Terminal Wires in Wire Harnesses

Wiring harness crimp terminal wire precautions crimp terminal wire is the core technology of all terminal wire production process, terminal wire as a commonly used signal transmission harness, in the application of modern electrical equipment, almost ubiquitous. Today we will talk about a few precautions for crimping terminal wires. In the technical process of crimping terminal wires, Huicheng Yuan, with years of experience in cable and wire harness assembly, has been strictly demanding precision crimping wire techniques to ensure that all crimped terminal wires meet industry standards and customer requirements. The following are a few precautions when crimping terminal wires as well as bad problems explained.

Insulation has no cuts or breaks; 2. Insulation is completely in and extends beyond the insulation crimp tabs; 3. Insulation is melted into strands and wires are not secured by crimping; 4. Contact has visible cracks and splits and no wire separation; 5. Wires should not be flat, twisted, bent, kinked or deformed; 6. Broken insulation can cause safety problems with the wire as well as potential hazards. 7. Insulation should be free of any signs of pinching, pulling, fraying, discoloration, charring, and burning; 8. Prepared wires must also be in solid working condition, not scratched, cut, severed, or damaged; 9. Insulation crimps are also required to fully support and wrap around the insulation to ensure that no damage or destruction of the insulation is caused; 10. Wires are retained in the connector with crimp indentations centered, and the insulation crimp must also be provided with a 180 degree of minimum side report. Crimping terminal wire process if there is a poor crimp, easily lead to terminal damage and back pin and other bad, choose DynaTek pressure management device, in the production process directly reject defective products. Pressure management device introduction pressure management system (CFM) is a crimping machine in the crimping process of the crimping force of the whole process monitoring equipment, in order to ensure the stability of crimping quality. The principle is to collect a certain number of good pressure waveforms (good waveforms) by means of device learning, and set threshold parameters to form production cases (reference waveforms). In the production process, production waveforms and reference waveforms compared to analyze, such as the difference between the value over (or less than) the threshold, it will automatically output an alarm signal, as well as pause the manufacturing process; for the alarm waveform manually selected to confirm the quality of the product, the alarm device will be automatically reset to continue the manufacturing process. It is mainly composed of strain gauge pressure sensor and pressure management system.
