In Terminal Wire Harness Processing, especially in medical harness processing, quality inspection is crucial and directly related to the safe and reliable operation of medical equipment. The following are the main quality inspection points during processing.
The first is wire inspection. Check whether the specifications of the wire meet the requirements, including wire diameter, length, color, etc. At the same time, detect the insulation performance of the wire to ensure that it can effectively prevent leakage and short circuit. Use an insulation resistance tester to test the wire to see if the insulation resistance value is within the specified range. In addition, check the flexibility and bending resistance of the wire to adapt to different use environments and installation requirements.
Terminal inspection is one of the key links. Check the appearance of the terminal to see if there are defects such as deformation, oxidation, and scratches. Ensure that the size of the terminal is accurate and the connection with the wire is firm. Use a tensile tester to perform a tensile test on the connection between the terminal and the wire to determine whether its bonding strength meets the standard. At the same time, detect the conductive performance of the terminal to ensure that the current can pass smoothly and avoid poor contact.
During the assembly process, check the overall appearance of the harness. Ensure that the wiring harness is neatly arranged without twisting or entanglement. Check whether the protective measures of the wiring harness, such as sleeves, tapes, etc., are installed in place to protect the wires and terminals. For multi-core wiring harnesses, check whether the markings of each core wire are clear and accurate for easy installation and maintenance.
Electrical performance testing is also essential. Use tools such as a multimeter to detect the conductivity of the wiring harness to ensure that each wire can be powered normally. Perform a withstand voltage test to check whether the wiring harness can maintain insulation performance under a certain voltage to prevent high-voltage breakdown. For medical wiring harnesses with special requirements, signal transmission performance testing may also be required to ensure the accuracy and stability of the signal.
Finally, strict finished product inspection is required. Perform a comprehensive appearance inspection and electrical performance review of the entire wiring harness to ensure that there are no quality problems. At the same time, check whether the packaging meets the requirements to ensure that the wiring harness is not damaged during transportation and storage.
In short, the key points of quality inspection in the Terminal Wire Harness Processing process cover wire materials, terminals, assembly, electrical performance and finished product inspection. Only by strictly controlling each link can the quality and reliability of medical wire harnesses be ensured.
