Wire harness processing in the analysis of common failures judgment How to ensure the quality of wire harness processing?

Wiring harness processing-The law of wiring harness burning out is: in the circuit of the power supply system, wherever there is ground, the wiring harness will burn out. The junction of the burned-out and intact parts can be considered as the ground of the wiring harness. For example, when the wiring harness burns out to the wiring part of an electrical equipment, it indicates that the electrical equipment is faulty. 1. The battery wire is burned out ① If only part of the battery wire is burned out, check the parts that are in contact with the burned part of the cable, clean the burrs and replace the battery wire. ② If all the battery wires are burned out, it means that the starter is malfunctioning. Connect the test light to the + pole of the starter electromagnetic switch and the positive pole of the battery. If the test light is on, it means that the electromagnetic switch has failed; If the test light does not light up, it means that there is an internal fault of the starter. 2. The wiring harness between the generator + pole and the starter battery terminal burns out and stops the generator. Remove the lead of the generator + pole. Connect a power cord between the battery + pole, and the other end is in contact with the generator + pole. If there is a spark, it means that the generator is faulty. If there is no spark, it means that the wiring harness is faulty. 3. The wiring harness and relay leads are burned out ① Turn off the power switch, remove the relay, let it hang in the air, and connect the test light between the relay shell and the car body. If the light is on, it means that the relay is faulty; If the light is not on, perform the following steps. ② Turn on the power switch. If the test light does not light up, it means that there is no fault in the relay. Only replace the wiring harness. If the test light indicates that the relay is faulty, the relay should be replaced.

Wire harness processing Wire harness is used in many industries. It is of great help in various industries and has a better performance in our lives. No matter what kind of products are produced in wire harness processing, there should be a problem involved in product quality control, so the same is true for wire harness processing. How should wire harness processing manufacturers control product quality? 1): It is necessary to train employees in related occupations. Each workshop arranges corresponding technical personnel to provide on-site guidance and solve problems, and also takes reward and punishment measures for employees. 2): A quality department can be added, which needs to supervise all aspects of wire harness processing every day, take corresponding photos, and then provide rewards and penalties on a weekly basis. 3): Update the existing production technology at any time, constantly measure the man hours and processes of wire processing, and constantly improve and correct the existing technology. 4): The production department should formulate production plans in a timely manner, and inform the technical and quality departments to monitor new products. Main products: communication wiring harnesses, medical equipment wiring harnesses, office equipment wiring harnesses, electrical wiring harnesses, automotive wiring harnesses, electric vehicles, lighting facilities wiring harnesses, and various special connecting wires, etc. Products are widely used in computers, household appliances, instruments, automobiles, machine tools, medical equipment, electronics, industrial automation, and other high-tech electrical products.
